Arguments for Theism

Cosmological

Arguments from Causation

Kalam

(P1) Everything that begins to exist has a cause. Something cannot come into being from nothing.

(P2) The universe began to exist.

(C1) Therefore, the universe has a cause.

(P3) If the universe has a cause, then an uncaused, personal Creator of the universe exists who sans the universe is beginningless, changeless, immaterial, timeless, spaceless, and enormously powerful. Personal: The first state of the universe cannot have a scientific explanation, since there is nothing before it, and therefore, it cannot be accounted for in terms of laws operating on initial conditions. It can only be accounted for in terms of an unembodied mind and his free volitions, a personal explanation.

(P4) The universe has a cause.

(C2) Therefore, an uncaused, personal Creator of the universe exists who sans the universe is beginningless, changeless, immaterial, timeless, spaceless, and enormously powerful.

+ Quantum physics claims that on the subatomic level, so-called “virtual particles” come into being from nothing.
1. Indeterministic particles do not come into being out of nothing. They arise as spontaneous fluctuations of energy in a rich structure subject to physical laws within a subatomic vacuum. A vacuum is not nothing. Nothingness is the absence of anything whatsoever. As such, nothingness can have no properties, since there literally is not anything to have any properties. 2. A great many physicists today are quite dissatisfied with the traditional Copenhagen interpretation of quantum physics. Most of the available interpretations of the mathematical formalism of Quantum Mechanics are fully casually deterministic.
+ The universe itself is eternal. It's always existed.
1. Philosophical Support -If the universe has always existed, the past events that occurred in history would be infinite. This would mean that for today to occur, every previous event would have had to happen. But if there is no starting point, it would be impossible to reach today, yet today clearly exists. This conclusion leads to absurdity. 2. Scientific Support -2nd Law of Thermodynamics: The universe is slowly running out of usable energy. If the universe had been here forever, it would have run out of usable energy by now. -The largely accepted BGV theorem, in modern cosmology, concludes there are no viable models of an eternal universe: "With the proof now in place, cosmologists can no longer hide behind the possibility of a past-eternal universe. There is no escape; they have to face the problem of a cosmic beginning." (Vilenkin, Many Worlds in One, p.176) "Almost everyone now believes that the universe, and time itself, had a beginning at the big bang." (Hawking and Penrose, The Nature of Space and Time, p.20)
+ What then caused God?
God is eternal, uncaused, self existent, who has no cause. God did not begin to exist.
+ This argument does not prove it is the God of the bible.
This is true. While it does show most of the attributes of the biblical God, it does not prove them all, and is not intended to. That said, if KCA is true it does rule out Atheism & Naturalism.

Contingency

(P1) Everything that exists has an explanation of its existence, either in the necessity of its own nature or in an external cause. (modest PSR) 17th century Leibniz original Principle of Sufficient Reason (PSR): "no fact can be real or existent, no statement true, unless there be a sufficient reason why it is so and not otherwise."

(P2) If the universe has an explanation of its existence, that explanation is grounded in a necessary being.

(P3) The universe exists.

(C1) Therefore, the universe has an explanation of its existence (from P1, P3).

(C2) Therefore, the explanation of the existence of the universe is grounded in a necessary being (from P2, C1).

(C3) Therefore, a necessary being exists (God).

+ The universe is a brute fact. It just exists inexplicably and there is no explanation of it's existence.
The scale of an existing thing does not excuse it from needing an explanation. Whether its a rock or an entire universe, it's very existence requires an explanation. From (P2), if the universe did have an explanation it could only be from something spaceless, timeless, immaterial, and metaphysically necessary in it's existence. This could be one of two options with the features above: 1. Abstract objects like numbers. 2. Unembodied mind. Abstract objects like numbers by definition stand in no causal relation. The number 2 cannot causally effect anything. So it is impossible for a number or an abstract object to be the cause of the universe, from which it therefore follows that the cause of the universe is plausibly an unembodied mind or consciousness, which is what the theist means by God.

Teleological

Arguments from Design

Cosmic Fine-Tuning

(P1) The fine-tuning of the universe is due to either physical necessity, chance, or design. By "fine-tuning" we mean that the fundamental constants and quantities of nature (e.g., the strength of gravity, the cosmological constant, the distribution of mass-energy in the early universe) fall within an extraordinarily narrow range that permits the existence of physical, interactive life. If these values were even slightly different, no life-permitting universe would exist.

(P2) It is not due to physical necessity or chance. Physical necessity would mean that the constants could not have been otherwise; chance would mean that they just happened to fall in the life-permitting range with no purpose or guiding intelligence. The probabilities involved, and the independence of the constants from the laws of nature themselves, strongly undermine both of these explanations.

(C1) Therefore, it is due to design.

Collins, Robin. “The Teleological Argument.” Pages 202–81 in The Blackwell Companion to Natural Theology. Edited by William Lane Craig and J. P. Moreland. Oxford: Wiley-Blackwell, 2009. Craig, William Lane. Reasonable Faith. 3rd ed. Wheaton: Crossway, 2008. [ch. 4]
+ The universe had to be life-permitting. The laws of nature make these constants and quantities necessary, so there is no real “fine-tuning” to explain.
1. Life-prohibiting universes are entirely possible. - Our best physics does not require the constants and quantities to have their present life-permitting values. The equations of nature are compatible with many different possible values, and the overwhelming majority of those values would result in a universe where no stars, planets, or chemistry could form, and therefore no complex life could exist. So a life-prohibiting universe is not only possible...it is far more likely than a life-permitting one. 2. The constants are not determined by deeper laws (as far as we know). - The fundamental constants (such as the gravitational constant and cosmological constant) appear as free parameters in our current theories. They are not fixed by the known laws themselves. There is no widely accepted physical theory that logically forces them to take the precise values required for life. 3. Fine-tuning is therefore real, not illusory. - Since many other sets of values are both physically possible and life-prohibiting, it is not true that the universe “had to” be life-permitting. The physical-necessity option fails, leaving the remarkable life-permitting fine-tuning still in need of explanation.
+ The fine-tuning is just a fluke. Yes, the odds are small, but someone has to win the cosmic lottery, and we are simply that lucky.
1. The probabilities are astronomically small. - The life-permitting range for several key constants is incredibly narrow. For example, if the strength of gravity were altered by just 1 part in 1060, or the cosmological constant by 1 part in 10120, the universe would not be life-permitting. When you consider multiple such parameters together, the probability of them all falling within the tiny life-permitting ranges by blind chance is unimaginably small. 2. Appealing to “brute luck” is not a satisfying explanation. - In ordinary reasoning, we do not treat extreme coincidences as adequately explained by saying “it just happened.” If you shuffled a deck and drew a perfectly ordered sequence (e.g., all cards in exact suit and rank order), you would not reasonably say, “Well, that’s improbable, but chance can produce any sequence.” Instead, you would rightly suspect that the deck was arranged on purpose. Likewise, the fine-tuning is so extreme that invoking sheer luck does not provide a serious explanatory alternative to design. 3. Fine-tuning cries out for a deeper cause. - The more extreme and systematic the appearance of ordering, the more rational it is to infer intention rather than accident. The cosmic fine-tuning is not a single isolated coincidence but a highly coordinated pattern across multiple independent parameters. This is exactly the sort of situation where design is a better explanation than chance.
+ A multiverse explains fine-tuning. If there are countless universes with different constants, it’s not surprising that at least one of them allows life, and we just happen to be in that one.
1. The multiverse is highly speculative and currently lacks direct evidence. - Some versions of inflationary cosmology or certain interpretations of quantum mechanics suggest the possibility of multiple universes, but we have no way to observe, test, or measure these supposed other universes. By definition, they lie beyond our observational horizon. In that sense, a “multiverse” is a philosophical or theoretical postulate, not an empirically established fact. 2. The "universe generator" itself would need to be fine-tuned. - To produce a wide range of universes, including life-permitting ones, the multiverse-generating mechanism must have very specific properties and laws. In other words, the “machine” that generates universes would itself require an enormous amount of fine-tuning. Thus, the multiverse does not remove the fine-tuning problem; it simply moves it up one level. 3. Small islands of order are more probable than a vast, ordered cosmos like ours. - In a multiverse where anything that can happen does happen, the most likely kind of “observer” is not one living in a large, lawful, life-permitting universe, but a minimal, short-lived fluctuation of order (sometimes called a “Boltzmann brain”). Statistically, tiny patches of order are far more probable than an entire universe filled with galaxies, stars, and billions of embodied observers. Yet what we actually observe is precisely the latter: a vast, stable, highly ordered cosmos filled with many observers. Even on multiverse assumptions, that is not what we would most expect to see. 4. Design remains the better explanation. - Even if some form of multiverse exists, it does not undercut the design hypothesis. At best, it would describe a larger context in which fine-tuning occurs. But we would still have to ask why there is a finely-tuned multiverse generator at all, and why it yields a universe like ours, which is rich in stable, law-governed order and observers. Design gives a simple, unified explanation of both the existence of a life-permitting universe and the deep order we see within it.
+ Even if the universe is designed, this argument doesn’t prove it’s the God of the Bible.
This is correct, and it is not what the argument is intended to do. The fine-tuning argument, like other arguments in natural theology, is a cumulative-case piece of evidence. It supports the existence of an intelligent, powerful, and transcendent designer of the universe, but it does not, by itself, establish every attribute of the God of Christian theism. Still, if the argument is sound, it does carry significant implications: • It rules out strict atheism and naturalism, which claim that the universe and its fundamental structure are ultimately unguided and purposeless. • It fits naturally with the biblical claim that “the heavens declare the glory of God” (Psalm 19:1–2), by showing that the basic structure of the cosmos points beyond itself to a rational Mind.

Applicability of Mathematics

(P1) If God does not exist, the applicability of mathematics to the physical world is just a happy coincidence. On naturalism, mathematical entities (numbers, sets, functions, equations) are non-physical and causally inert. They cannot cause anything in the physical world. So if there is no divine mind ordering reality, the fact that the physical universe behaves in precise accordance with abstract mathematics is, at best, an unexplained coincidence.

(P2) The applicability of mathematics to the physical world is not just a happy coincidence. Mathematics does not merely organize data after the fact; it successfully predicts new phenomena (e.g., planets, radio waves, the Higgs boson) using highly abstract structures (imaginary numbers, higher-dimensional spaces, etc.). As Eugene Wigner put it, the “unreasonable effectiveness of mathematics” is so striking that he called it a “miracle which we neither understand nor deserve.”

(C1) Therefore, God exists.

Eugene Wigner, “The Unreasonable Effectiveness of Mathematics in the Natural Sciences,” Communications on Pure and Applied Mathematics 13 (1960): 1–14. William Lane Craig, “God and the Unreasonable Effectiveness of Mathematics,” ReasonableFaith.org. https://www.reasonablefaith.org/writings/question-answer/god-and-the-unreasonable-effectiveness-of-mathematics/
+ It is not surprising that mathematics applies. The physical world just happens to have a mathematical structure, so of course mathematics describes it. No God needed.
1. This assumes, rather than explains, the mathematical structure of the world. - Saying “the world just has a mathematical structure” simply restates the phenomenon to be explained. It does not tell us why the universe, down to its fundamental laws, is so deeply and elegantly structured in a way that can be captured by human mathematics. 2. Much of the mathematics used in physics goes beyond what is physically realizable. - Modern physics relies on highly abstract mathematics such as imaginary numbers, complex-valued wave functions, and infinite-dimensional Hilbert spaces. Physical reality cannot literally have the structure described by many of these mathematical objects, yet they are indispensable for accurately describing and predicting physical phenomena. 3. The depth and elegance of the fit still cries out for an explanation. - Not only is the world describable mathematically; it is describable by remarkably simple, elegant equations (e.g., Maxwell’s equations, Einstein’s field equations). On theism, this is expected: a rational God chooses to create an ordered universe according to a rational, mathematical plan. On bare naturalism, this striking fit remains a brute, unexplained fact.
+ Mathematics is a human invention or useful fiction. We created mathematical systems that fit the world, so it is no surprise they “work.”
1. Our best scientific practice treats mathematics as discovered, not merely invented. - Scientists routinely speak as if they are discovering mathematical structures already “out there,” not arbitrarily making them up. For example, Einstein used mathematical theories developed decades earlier and found that they unexpectedly described the structure of space-time. That looks more like discovery than free invention. 2. Abstract mathematics often proves effective in ways no one anticipated. - Many mathematical theories were developed with no application in mind (e.g., non-Euclidean geometry, group theory, complex analysis). Yet later they turned out to be essential for physics (relativity, particle physics, quantum theory). This surprising, long-delayed applicability is hard to explain if math is just a convenient human fiction tailored to fit the data. 3. Fictional entities do not usually make precise, novel predictions. - Pure inventions or fictions do not typically yield highly precise, testable predictions about the physical world, like the existence and location of a new planet or particle (e.g., Neptune, the Higgs boson). The uncanny success of abstract mathematics in predicting new physical realities is much more naturally explained if there is a deep, mind-based harmony between the mathematical order in God’s mind and the created world.
+ We can explain applicability through mathematical Platonism. Mathematical objects exist in an abstract realm, and the physical world simply instantiates that structure. No need to bring God into it.
1. Platonism still leaves the key connection unexplained. - On Platonism, mathematical entities (numbers, sets, functions) exist in a timeless, non-physical realm. But why should a contingent, physical universe line up so precisely with that realm? Why should the laws of nature mirror specific parts of the Platonic realm rather than countless others? Platonism affirms the existence of mathematics; it does not by itself explain its tight fit with the physical world. 2. Platonism cannot explain why we can know and use this abstract realm. - If mathematical objects exist in a separate, non-empirical realm, why should finite, embodied creatures like us have reliable access to that realm and be able to apply it so effectively to physical reality? On theism, both our minds and the mathematical order of the universe come from the same divine mind, which naturally explains the match. 3. Theism unifies what Platonism leaves disconnected. - Theism can affirm the reality and necessity of mathematical truths (as ideas in the mind of God) while also explaining why the physical universe is structured according to them: God freely chooses to create a world that reflects His rational nature. Thus, the applicability of mathematics is not a cosmic coincidence, but the outworking of a single, personal source.
+ Even if the argument works, it does not prove that the designer is the God of the Bible.
This is correct, and it is not what the argument is intended to do. The applicability-of-mathematics argument is part of natural theology: it aims to show that there is a rational, transcendent mind behind the mathematical order of the universe, not to establish every detail of Christian doctrine. Still, if the argument is sound, it has important implications: - It rules out strict atheism and naturalism, according to which the deep harmony between abstract mathematics, the human mind, and the physical world is ultimately groundless and accidental. - It fits naturally with the biblical picture of a God who creates “by wisdom” and orders the cosmos in a way that can be understood (at least in part) by creatures made in His image.

Moral & Rational

Arguments from Morality & Reason

Moral Argument

(P1) If God does not exist, objective moral values and duties do not exist. Without God, there is no objective reference point for right and wrong beyond individual or cultural opinion. On atheistic naturalism, humans are accidental products of blind processes; moral judgments then reduce to subjective preferences or social conventions, not binding truths that hold regardless of what anyone thinks.

(P2) Objective moral values and duties do exist. Our moral experience strongly testifies that some things are really good or evil, right or wrong (e.g., love vs. cruelty, justice vs. child abuse). As surely as we trust our sense experience of the physical world, we trust our moral experience that certain acts are objectively wrong for everyone, always, regardless of opinions or cultures.

(C1) Therefore, God exists.

William Lane Craig, Reasonable Faith: Christian Truth and Apologetics, 3rd ed. Wheaton, IL: Crossway, 2008. Reasonablefaith.org. “Can We Be Good Without God?” and other moral argument resources. https://www.reasonablefaith.org/writings/popular-writings/existence-nature-of-god/can-we-be-good-without-god/
+ People can be good without believing in God, so God is not needed for morality.
1. The argument is about the foundation of morality, not belief in it. - The moral argument does not claim that you must believe in God in order to live a decent life or recognize right and wrong. Many atheists and agnostics live morally admirable lives and make sharp moral judgments. 2. Distinguish moral epistemology from moral ontology. - Moral epistemology: how we come to know moral truths. - Moral ontology: what makes those truths objectively valid in the first place. - The argument concerns ontology: what ultimately grounds the truth of moral claims like “torturing children for fun is wrong” or “all humans have equal moral worth.” It says that if there is no God, nothing makes such claims objectively and universally binding. 3. Non-believers can know and live moral truths grounded in God. - On Christian theism, all people are created in God’s image and have a God-given moral conscience (Romans 2:14–15). So even those who reject belief in God can still recognize and act on objective moral truths that, on this view, are ultimately grounded in God’s nature.
+ Morality can be explained by evolution and social conditioning. We don’t need God; we just evolved moral feelings because they helped our ancestors survive.
1. Evolution can explain how we come to have moral beliefs, not whether they are true. - Describing a process (e.g., “we evolved to think cooperation is good”) is not the same as providing a justification. Evolutionary accounts might explain why we believe certain things, but they do not show that those beliefs correspond to any objective moral reality. 2. On naturalism, evolution tends toward survival, not moral truth. - If humans are the result of unguided evolutionary processes, then our moral feelings are aimed at reproductive fitness, not at tracking objective moral facts. This undercuts confidence that our moral judgments are true in any deep sense; they are just useful survival instincts. 3. Evolutionary history cannot turn mere preferences into objective obligations. - Even if evolution explains why we dislike murder or value fairness, it does not by itself make murder really wrong or fairness really good. It only shows that we happen to have those feelings. Objective “oughts” (“you should not torture,” “you ought to treat people as equals”) require a transcendent standard that is independent of our biological programming and cultural upbringing.
+ Objective morality can exist without God, grounded in things like human flourishing, reason, or intrinsic properties of persons.
1. On naturalism, it is hard to see why humans have objective, intrinsic moral worth. - If humans are ultimately arrangements of matter produced by blind processes, why should they have more objective value than other animals or than rocks? Calling human flourishing “good” on atheism often turns out to be a re-description of what we happen to prefer, not a truly binding, mind-independent moral standard. 2. Reason alone cannot generate moral obligation. - Reason can tell you how to achieve a goal (“If you want X, you should do Y”), but it cannot by itself tell you what you ought to value in the first place. Without a personal, authoritative moral lawgiver, it is difficult to explain why we are objectively obligated to be rational, fair, or compassionate, as opposed to selfish or indifferent. 3. Theism provides a natural foundation for both value and duty. - On Christian theism: - Objective moral values are grounded in God’s perfect, unchanging nature (God is good). - Objective moral duties are grounded in God’s commands, which express His nature (e.g., “love your neighbor as yourself”). - This accounts for why persons have intrinsic worth (they bear the image of God), and why we are truly obligated to act in certain ways (we stand under the authority of a perfectly good moral Lawgiver).
+ Euthyphro Dilemma: If morality depends on God, then either right and wrong are arbitrary (whatever God wills), or there is a standard of good independent of God.
1. Classical theism offers a third option. - The moral argument does not say “things are good just because God commands them” (which would be arbitrary), nor does it say “God commands them because they are good by a standard outside Himself.” Instead, it says God commands what He does because He is good. God’s own perfectly good nature is the standard. 2. God’s nature is essentially and unchangeably good. - God is, by nature, loving, just, and holy. He does not arbitrarily decide that cruelty is good one day and evil the next. His commands flow necessarily and consistently from who He is. Thus, goodness is neither independent of God nor a matter of sheer divine whim; it is rooted in God’s very being. 3. This preserves both God’s sovereignty and the objectivity of morality. - Because moral values are grounded in God’s nature, they are objective and independent of human opinion. Because moral duties are grounded in God’s commands, they are authoritative and binding. The Euthyphro dilemma assumes a false either/or that classical theism does not accept.
+ History is full of moral disagreements and even religiously motivated atrocities. Doesn’t this show that there are no objective moral truths?
1. Disagreement does not imply non-existence. - People disagree about philosophical questions and scientific theories, but we do not conclude there is no truth about those matters. Likewise, moral disagreement does not show there is no objective moral truth; it may simply show that some people are mistaken. 2. Our moral outrage presupposes objective standards. - When we condemn genocide, racism, or abuse (even when done in the name of religion), we are not merely saying “we dislike that.” We are saying that such acts are really wrong and should not be done. That very judgment presupposes an objective moral standard by which we evaluate such behavior. 3. Abuse of a standard does not invalidate the standard. - That some people misuse moral or religious language to justify evil does not mean there is no genuine moral law. It shows, instead, that people can twist what is good for evil ends. The reality of evil and moral failure is precisely what you would expect if there is an objective moral law and humans often rebel against it.

Free-Thinking Argument

(P1) If robust naturalism is true, then God or things like God do not exist. Robust naturalism is the view that only physical things exist...no God, no immaterial souls, no abstract minds. Reality is exhausted by space-time, matter/energy, and the laws of nature.

(P2) If God or things like God do not exist, then humanity does not freely think in the libertarian sense. On a purely naturalistic picture, all human thoughts are the result of prior physical causes (e.g., brain chemistry, genetics, environment). This yields at best determinism (or indeterministic randomness), not genuine libertarian freedom to choose between alternatives in our thinking.

(P3) If humanity does not freely think in the libertarian sense, then humanity is never epistemically responsible. To be epistemically responsible...to be genuinely praiseworthy or blameworthy for what we believe...we must have some control over our thinking: we must be able to assess reasons, weigh evidence, and choose between competing beliefs. If our beliefs are entirely fixed by non-rational, prior physical causes, we are not truly responsible for holding them.

(P4) Humanity is occasionally epistemically responsible. In ordinary life we routinely treat people (including ourselves) as genuinely responsible for at least some of their beliefs...e.g., for ignoring evidence, being intellectually dishonest, or carefully weighing arguments. Our practices of rational praise and blame presuppose that people sometimes can freely choose how to respond to reasons.

(C1) Therefore, humanity freely thinks in the libertarian sense. (from P3 and P4, modus tollens)

(C2) Therefore, God or things like God exist. (from P1 and P2 and C1)

(C3) Therefore, robust naturalism is false. (from P1 and C2, modus tollens)

(P5) The biblical account of reality is one possible explanation for the existence of God, things like God, and the libertarian freedom of humanity.

(P6) If the biblical account provides a better explanation of these facts than alternative accounts, then it is reasonable to accept it as the best explanation.

(C4) Therefore, if the biblical account provides the best explanation, it is reasonable to accept it. (from P5 and P6, abduction to the best explanation)

Stratton, Timothy A., and J. P. Moreland. “An Explanation and Defense of the Free-Thinking Argument.” Religions 13, no. 10 (2022): 988. https://doi.org/10.3390/rel13100988
+ We don’t need libertarian free will for rational responsibility; compatibilist freedom under natural laws is enough.
1. Compatibilism redefines freedom in a weaker sense. - On compatibilism, you are “free” as long as you act according to your strongest desires, even if those desires are fully determined by prior causes. But this is not the robust, “could have done otherwise” freedom the argument is about. Libertarian freedom says that, given exactly the same past and laws of nature, you still genuinely could have chosen a different belief or response to reasons. 2. If all your beliefs are fully determined by non-rational causes, rational control is an illusion. - If naturalism is true and every belief you hold is the unavoidable result of prior physical states, then you never truly choose beliefs because of what you judge to be the best reasons. You only feel like you are reasoning freely, while in reality your mental life is fixed by factors beyond your control. 3. Epistemic praise and blame presuppose libertarian-like control. - We hold people epistemically responsible when we think they could have investigated more carefully, examined their biases, or changed their mind in light of evidence. This fits libertarian freedom naturally, but undercuts itself on a strictly deterministic, compatibilist naturalism.
+ Neuroscience shows our thoughts are just brain events. There’s no immaterial soul or libertarian freedom needed.
1. Correlation is not identity. - The fact that certain brain states correlate with certain thoughts does not show that thoughts are nothing but brain states. It only shows a close connection between mind and brain...a connection perfectly compatible with a soul or immaterial aspect of the person working through the brain. 2. Physical descriptions leave out the normative, rational aspect of thought. - Brain science can describe spikes, voltages, and chemical releases, but it does not capture the aboutness and rightness/wrongness of beliefs (e.g., “2+2=4 is true,” “torturing innocents is wrong”). These are normative, semantic features that go beyond mere physics. 3. If our thoughts are fully determined by non-rational physical causes, their reliability is undermined. - On strict physicalism, your belief in physicalism itself is produced by the same blind processes as any other belief. That undercuts your confidence that the belief is true rather than just a useful byproduct of survival. A theistic view with libertarian freedom allows that we can genuinely align our beliefs with reasons and truth, not just neurochemistry.
+ Even if our thinking is caused by the brain, we can still talk about epistemic responsibility in terms of social practices and internal coherence.
1. Redefining responsibility in pragmatic terms dodges the core issue. - Saying “we call people responsible when they respond in certain ways” only describes our social practice; it doesn’t show that people really could have done otherwise in their thinking. The argument is about genuine responsibility, not just useful labels. 2. Without libertarian control, ‘ought’ collapses into ‘is’. - If every belief you form is completely fixed by prior physical conditions, then strictly speaking you never ought to have believed differently...because you could not have. Terms like “should have checked the evidence” lose their literal meaning and become mere expressions of preference or social disapproval. 3. Naturalism’s own defense presupposes the kind of responsibility it denies. - When a naturalist argues for naturalism and against theism, they expect you to weigh reasons and choose the better view. But if their worldview is true and no one ever has libertarian control over beliefs, then even their own belief in naturalism is just the inevitable outcome of physical processes, not a rationally chosen conclusion.
+ Even if the argument shows robust naturalism is false, it doesn’t prove that Christianity...or the biblical God...is true.
This is correct, and it is not what the argument is designed to do. The Free-Thinking Argument aims to show: - That libertarian free thought exists. - That this is incompatible with robust naturalism. - That therefore some kind of God or God-like reality exists. It does not, by itself, identify which theistic worldview is true. However, it does have important implications: - It undermines strict naturalism as a complete account of reality. - It opens the door to worldviews that include an immaterial, rational source of our freedom and reason. From there, further arguments and evidence (historical, moral, cosmological, biblical) can be brought in to compare different theistic options. The biblical account is one such candidate, and if it offers the best overall explanation of: - God’s existence, - the existence of souls or immaterial minds, - and genuine libertarian freedom, then, as P5–P6 state, it is reasonable to accept it as the best explanation.

Evolutionary Argument Against Naturalism (EAAN)

(P1) If naturalism and unguided evolution are both true, then the probability that our cognitive faculties are reliable is low or inscrutable. On naturalism, humans are the result of unguided evolutionary processes aimed at survival and reproduction, not at producing true beliefs as such. Evolution selects for behavior that enhances fitness, whether or not the underlying beliefs are true.

(P2) If the probability that our cognitive faculties are reliable is low or inscrutable, then we have a defeater for trusting the deliverances of those faculties. If you have good reason to doubt that your thinking is generally truth-tracking, then you also have good reason to doubt the beliefs produced by that thinking...including your belief in naturalism and evolution themselves.

(P3) If we have a defeater for trusting our cognitive faculties, then we have a defeater for any belief produced by those faculties, including belief in naturalism and unguided evolution. Belief in naturalism and in the truth of evolutionary theory is itself formed by our cognitive faculties. So if those faculties are undercut, these beliefs are undercut as well.

(P4) Therefore, if naturalism and unguided evolution are both true, we have a defeater for believing that naturalism and unguided evolution are true. (from P1–P3)

(C1) Therefore, naturalism is self-defeating and cannot be rationally affirmed together with unguided evolution.

(P5) Theism offers a better explanation of the reliability of our cognitive faculties than naturalism with unguided evolution. On theism, a rational God creates humans in His image with cognitive faculties designed for truth, not merely for survival. This gives us a positive reason to trust our minds as generally reliable.

(C2) Therefore, the reliability of our cognitive faculties provides evidence in favor of theism over naturalism.

+ Evolution selects for reliable cognitive faculties because having true beliefs usually helps an organism survive and reproduce.
1. Behavior, not belief content, is what evolution ‘sees’. - Natural selection operates on behavior and physiology, not directly on the truth of beliefs. What matters for survival is how an organism acts, not whether its inner representations of the world are true. 2. Many false-belief systems can still produce adaptive behavior. - Plantinga’s point is that there are countless possible combinations of false beliefs and desires that would yield the same survival-enhancing behavior. For example, a hominid who runs from tigers because he believes “I must always be moving fast to earn the sun god’s approval” will behave in a survival-promoting way, even though his beliefs are mostly false. 3. Evolution alone does not make high reliability probable. - Because adaptive behavior can be generated by many wildly false belief-desire pairs, we cannot simply assume that unguided evolution strongly favors truth over falsehood. At best, evolution might favor systems that are locally useful for survival in certain environments, not globally truth-tracking across abstract domains (metaphysics, mathematics, theology, long-range science, etc.).
+ Even if evolution doesn’t guarantee perfect reliability, it could still make it likely that our faculties are mostly reliable, and that’s enough.
1. The EAAN targets the probability of ‘sufficient reliability’ under naturalism. - Plantinga’s argument does not require our faculties to be perfect. It asks whether, given naturalism and unguided evolution, it is probable enough that our cognitive faculties are reliable in the sense needed for science, philosophy, and ordinary reasoning. 2. Under naturalism, this probability is hard to justify. - If evolution is blind to truth as such and only tracks fitness, then there is no strong reason to think that the resulting cognitive systems will be broadly reliable beyond the narrow tasks of staying alive and reproducing. Our sophisticated theoretical reasoning (about quantum physics, abstract logic, metaphysics, ethics, etc.) goes far beyond what is strictly needed for survival. 3. A low or inscrutable probability still generates a defeater. - If, given naturalism and evolution, you should regard the reliability of your cognitive faculties as low or at best inscrutable, then you have a reason to withhold trust from the deliverances of those faculties...including your belief that naturalism and evolution are true. That is enough for the argument’s self-defeat conclusion.
+ If evolution undercuts trust in our cognitive faculties, then theists who accept evolution are also undermining their own beliefs.
1. The key problem is the combination of naturalism with unguided evolution. - The EAAN specifically targets the conjunction: naturalism and unguided evolution. On theism, evolution can be understood as a tool that God uses providentially. In that case, our cognitive faculties can be both shaped by evolutionary processes and also aimed at truth by a rational Designer. 2. Theism provides a positive reason to expect reliability. - If God is good and rational, and He intends creatures to know Him and the world, then it is expected that He would create beings with cognitive faculties generally aimed at truth. Evolutionary mechanisms can be part of this design plan. 3. Naturalism lacks this truth-aiming intention. - On robust naturalism, there is no personal mind planning for truth-tracking faculties...only blind processes that care about survival outcomes. That is why the naturalist, not the theist, faces the special problem of an undercutting defeater for trusting reason.
+ At best the EAAN pushes us toward global skepticism, not toward God. Why think theism is the solution?
1. The EAAN is primarily an internal critique of naturalism. - The main conclusion is that naturalism combined with unguided evolution is self-defeating: it undercuts any rational ground for believing itself. That is an important result, even before we compare alternative worldviews. 2. Our deep commitment to trusting reason points beyond naturalism. - In practice, we cannot live as if our cognitive faculties are radically unreliable. We rely on memory, perception, logic, and inference in every domain of life. If naturalism makes such trust irrational, that is a powerful reason to look for a worldview that better supports reason. 3. Theism offers a natural fit between God, mind, and world. - On theism, a rational God creates: - a rationally ordered world, - finite minds in His image, - and a fit between those minds and the world, so that truth is knowable. - This provides a positive explanatory framework in which our trust in reason makes sense, rather than being a lucky cosmic accident. The EAAN, therefore, clears the ground by undermining naturalism and simultaneously highlights the explanatory power of a theistic picture of reality.

Modal Ontological (Maximal Greatness)

(P1) It is possible that a maximally great being exists. A "maximally great being" is one that has maximal excellence (omnipotence, omniscience, moral perfection, etc.) in every possible world. In other words, if such a being exists, it exists necessarily and cannot fail to exist.

(P2) If it is possible that a maximally great being exists, then a maximally great being exists in some possible world. In modal logic, "possibly exists" means "exists in at least one possible world" (a complete way reality could have been).

(P3) If a maximally great being exists in some possible world, then it exists in every possible world. By definition, a maximally great being has necessary existence. If such a being exists in any possible world, it must exist in all possible worlds (it cannot be "contingent").

(P4) If a maximally great being exists in every possible world, then it exists in the actual world. The actual world is one of the possible worlds. If a being exists in every possible world, it exists in this one too.

(P5) If a maximally great being exists in the actual world, then a maximally great being exists. If such a being exists in our world, then it simply exists...God is real.

(C1) Therefore, a maximally great being exists.

Alvin Plantinga (ed.), The Ontological Argument. Garden City, NY: Doubleday, 1965. Anselm of Canterbury. Proslogion. Translated by Clement C. J. Webb. In The Devotions of St. Anselm. 1903.
+ The argument just defines God into existence by using fancy modal logic.
1. Not every definition yields a real thing. - Simply defining something does not make it real. The ontological argument does not say, "By definition God exists," and stop there. Rather, it asks whether the existence of a certain kind of being (a maximally great, necessarily existent being) is possible. 2. The key issue is whether God's existence is possible, not actual. - If the idea of a maximally great being is coherent (not contradictory), then it is possible such a being exists. But on standard modal principles, once you grant that such a necessarily existent being is possible, it follows that it is actual. The argument trades on the special nature of necessary existence, not on a mere definition trick. 3. Parody "arguments" (islands, pizzas, unicorns) fail because their concepts don't support maximal greatness. - Consider a "maximally great island": you could always add more palm trees, more waterfalls, more beaches. There is no obvious intrinsic maximum of island-greatness. The same goes for a "maximally great pizza" (you can always add more toppings, more cheese, etc.) or a "maximally great unicorn" (you can always imagine a slightly faster, more beautiful, more powerful unicorn). These are all contingent, finite objects whose properties admit of open-ended improvement. - By contrast, the properties attributed to a maximally great being...omniscience, omnipotence, and moral perfection...are by their nature absolute and non-gradual. There is no "one notch greater" than knowing all truths, having all power logically possible, or being morally perfect. These are true maxima. 4. Only the theistic concept is suited to necessary existence. - Islands, pizzas, and unicorns, even in parody form, are the kinds of things that could exist in some worlds and not in others. It is part of our understanding of them that they are contingent and dependent. A "necessarily existent island" or "necessarily existent pizza" is a category mistake, not a serious philosophical concept. - The concept of a maximally great being, however, includes necessary existence as part of its greatness. If such a being is even possible, it cannot exist in just one world by accident; it must exist in all possible worlds. That is why the modal ontological argument targets God specifically, and why the parody objects fail as true parallels.
+ If you can argue for a maximally great good being, you could just as easily argue for a maximally great evil being.
1. Maximal greatness includes moral perfection, not moral evil. - By definition, a maximally great being has maximal excellence in every possible world, which includes maximal moral goodness. A "maximally evil" being would lack the moral perfection that is part of maximal greatness and thus would not be maximally great. 2. Moral evil is a privation, not a greatness-making property. - Traditionally, evil is understood as a corruption or lack of good, not as a positive excellence. Traits like justice, love, wisdom, and holiness are perfections; cruelty, malice, and injustice are defects. So you cannot construct a parallel argument by simply switching out goodness for evil without changing the very idea of "greatness." 3. The concept of a necessarily and maximally evil being is incoherent. - A necessarily evil being would be one that is evil in every possible world. But if such a being is also omniscient and omnipotent, it could recognize the good and have the power to choose it. A will that is necessarily and maximally opposed to all good is not a coherent perfection in the way that maximal goodness is.
+ P1 assumes that it is possible a maximally great being exists. But maybe God is impossible due to hidden contradictions.
1. The question becomes: is the concept of God coherent? - The argument forces the debate onto whether the very idea of a maximally great being (omnipotent, omniscient, morally perfect, necessarily existent) is internally consistent. If critics claim it is impossible, they need to show an actual contradiction, not just say "I don't like it." 2. Many alleged contradictions have been carefully answered in the literature. - Philosophers have proposed various challenges (e.g., paradoxes about omnipotence, foreknowledge, or freedom), but Christian philosophers have developed detailed responses showing these are not genuine contradictions. Unless an actual inconsistency is demonstrated, it is reasonable to treat God's existence as at least possible. 3. The argument is a powerful "if-then" tool. - Even if someone is unsure about P1, the ontological argument still shows: if God's existence is even possible, then God exists necessarily. That is a striking result, and it means that those who think God's existence is even possibly true are logically committed to His actual existence.
+ At best this argument shows some "maximally great being" exists, not that it is the God of the Bible.
This is correct, and it is not what the ontological argument is meant to do by itself. Properly understood, it aims to establish that: - There exists a necessarily existent, personal being with maximal greatness (omnipotence, omniscience, and moral perfection) in every possible world. This already rules out: - Atheism and robust naturalism. - Finite or morally imperfect "gods." From there, further arguments (cosmological, moral, historical) and evidence from revelation can be used to identify this maximally great being more specifically with the God revealed in Scripture. The ontological argument is one important piece of a larger cumulative case.

Five Ways

Arguments from Thomas Aquinas (1225-1274)

First Way – From Motion/Change

(P1) Things in the world are in motion (undergoing change). By “motion,” Aquinas means change in a broad sense (e.g., from potential to actual): local motion, growth, decay, heating, cooling, etc. Our everyday experience and all of natural science presuppose that real change occurs.

(P2) Whatever is moved (changed) is moved by another. A thing cannot be actually changing in respect of some feature while remaining purely potential in that same respect, all by itself. For example, a piece of wood does not go from cold to hot by itself; it is heated by something already hot. Change from potentiality to actuality requires something already actual as its cause.

(P3) There cannot be an infinite regress of essentially ordered movers (causes of motion). In a here-and-now (essential) causal series...like a hand moving a stick moving a stone...the intermediate movers have causal power only by being moved/actualized by something prior in the series. If there were no first actualizer in such a series, there would be no motion at all, just as a train of cars cannot move without some engine.

(C1) Therefore, there exists a first unmoved mover: something that causes motion (change) in others without itself being moved (changed) by another in the same way.

(C2) This first unmoved mover is what we call God.

Thomas Aquinas, Summa Theologiae, I, q. 2, a. 3 (“Whether God exists?”) – First Way. Edward Feser, Aquinas. Oxford: Oneworld, 2009.
+ Modern physics already explains motion and change (e.g., with laws of motion and energy). Aquinas’ argument is outdated.
1. Aquinas is giving a metaphysical explanation, not a competing physical theory. - Physics describes how motion and change occur in terms of laws, forces, and fields. Aquinas is asking a deeper question: why is there any actualization of potentials at all, here and now, rather than everything remaining merely potential? 2. Laws of nature are not self-explanatory. - Saying “things move according to the laws of physics” does not explain why there are such laws, why they hold now, or why the underlying powers and potentials are being actualized rather than remaining dormant. Aquinas is looking for a first actualizer that makes all ongoing change possible. 3. The First Way is compatible with whatever physics discovers. - Whether reality is described in terms of Newtonian mechanics, relativity, or quantum field theory, there is still a real distinction between potential and actual, and still chains of dependent, here-and-now actualizations. The argument does not depend on medieval science; it depends on the metaphysical structure of change itself.
+ Maybe there is just an infinite chain of things moving other things. Why must there be a first unmoved mover?
1. Aquinas targets ‘essential’ (here-and-now) dependence, not merely a past series. - Aquinas is not primarily arguing that the universe must have had a temporal beginning. Rather, he is focusing on present, simultaneous dependence: here and now, many things are being actualized by others in an ordered series. 2. An essentially ordered series cannot regress infinitely in dependence. - In a series like hand–stick–stone, the stick moves the stone only because the hand is moving the stick. If you remove the hand, the stick has no independent power to move the stone. If every member of the series were only a “borrowed” mover, with no first source, nothing would move at all. 3. A first mover is needed as the source of actual causal power. - The first unmoved mover is not just the temporally first cause long ago; it is the present, sustaining source of motion and change. An infinite regress of borrowed movers, with no ultimate source, would be like an endless series of extension cords plugged into one another with no appliance ever plugged into the wall...no real power would ever flow.
+ At most, this gives some abstract ‘first mover,’ not the personal God of Christianity.
1. Aquinas himself goes on to derive divine attributes from the First Way’s conclusion. - In the Summa, Aquinas does not stop at “there is an unmoved mover.” He argues that this being must be purely actual (with no unrealized potentials), immutable, eternal, immaterial, absolutely simple, and the cause of all other beings. From there, he argues it must also be intelligent, good, and ultimately personal. 2. A purely actual first mover already excludes many non-theistic options. - A being that is the first unmoved mover and purely actual cannot be a finite, composite, changeable, or morally imperfect “god” alongside others. It is the unique, ultimate source of all actuality in everything else. 3. The Five Ways together are part of a larger, cumulative case. - The First Way on its own is not meant to prove every detail of Christian doctrine. Rather, it contributes one powerful strand: from change to a purely actual source of all motion. Other arguments (from contingency, degrees of perfection, finality, revelation, and history) fill out the picture and connect this first mover to the God revealed in Scripture.

Second Way – From Efficient Cause

(P1) In the world of sense, we find an order of efficient causes. By an “efficient cause,” Aquinas means that which brings something into being or sustains it (e.g., a builder causing a house, fire causing heat, parents causing a child). Our experience and all of science presuppose that things have causes.

(P2) Nothing can be the efficient cause of itself. If something caused itself to exist, it would have to exist before it existed, which is impossible. A cause must be distinct from its effect at least in the order of explanation: the effect depends on the cause, not vice versa.

(P3) There cannot be an infinite regress of essentially ordered efficient causes. In an essentially ordered series of causes (here-and-now dependence), intermediate causes have causal power only because they receive it from prior causes. If there were no first cause in such a series, there would be no causal activity at all, like a series of gears with no primary driving gear.

(C1) Therefore, there must be a first efficient cause that is not itself caused by anything else.

(C2) This first uncaused cause is what we call God.

Thomas Aquinas, Summa Theologiae, I, q. 2, a. 3 (“Whether God exists?”) – Second Way. Edward Feser, Aquinas. Oxford: Oneworld, 2009. Norman Kretzmann and Eleonore Stump, “Being and Goodness,” in The Cambridge Companion to Aquinas, ed. Kretzmann and Stump. Cambridge: Cambridge University Press, 1993.
+ Maybe there is just an infinite chain of causes. Why must there be a first, uncaused cause?
1. Aquinas distinguishes between accidental and essential causal series. - An accidental series is like father–son–grandson: once the son exists, the father can die and the son can still beget children. The earlier cause need not still be acting. - An essential series is like hand–stick–stone: the stick moves the stone only because the hand is currently moving the stick. Remove the hand, and the stick has no power to move anything. 2. The Second Way focuses on essential, here-and-now dependence. - Aquinas argues that with respect to the existence and activity of things right now, there is an essentially ordered series of causes. Each finite cause has its causal power only in a derivative, received way. 3. An infinite regress of essentially ordered causes would leave nothing actually causing. - If every member of the series only had causal power on loan from a prior member, and there were no first source, then no member would truly have causal power, and no effects would occur. A first uncaused cause is needed as the ultimate source of causal efficacy.
+ Quantum physics suggests that some events (like particle decays) happen without causes. Doesn’t that undermine the Second Way?
1. ‘Uncaused’ in quantum mechanics is a technical, not absolute, claim. - When physicists say an event is “uncaused,” they usually mean it is not determined by prior states in a classical, predictable way, not that it has literally no cause or explanation whatsoever. 2. Quantum events still presuppose an underlying causal structure. - Quantum processes occur within a framework of quantum fields, laws, boundary conditions, and conserved quantities. They do not occur in an absolute void. Aquinas’ principle concerns the more basic metaphysical idea that potentialities become actual only through some actual cause. 3. The Second Way is compatible with indeterministic physical models. - Even if some events are probabilistic rather than strictly determined, the existence of the fields, laws, and powers that give rise to such events still calls for a sustaining cause. The argument does not depend on a strictly deterministic physics.
+ Suppose there is a first uncaused cause. Why identify it with the God of classical theism rather than some impersonal force?
1. An uncaused cause of all finite beings must be necessary and non-dependent. - The first cause cannot itself be contingent or dependent on anything else, or it would not be truly first. It must exist of itself (be a necessary being), and this already sets it apart from all finite, changeable things. 2. Aquinas argues that the first cause must also be simple, immaterial, and intelligent. - A first cause of all finite beings cannot be composed of parts (which would require causes to combine them), cannot be material in the usual sense (since matter is characterized by potentiality and limitation), and must be the source of all order and intelligibility in the world. From this, Aquinas concludes that the first cause is an intelligent, willing agent, not a blind “thing.” 3. The Second Way is a step in identifying the God of classical theism. - On its own, the Second Way does not prove every divine attribute or the truth of Christianity, but it points us toward a unique, uncaused, necessary source of all finite reality. In Aquinas’ larger project, the Five Ways together, plus further analysis, build toward the God of classical theism.
+ The Second Way relies on outdated Aristotelian metaphysics (causes, substances, etc.). Modern science has moved beyond that.
1. Aquinas’ causal principles are philosophical, not scientific hypotheses. - The claim that nothing can cause itself, and that essentially ordered causal chains require a first cause, is a metaphysical claim about dependence and explanation. It is not a law of physics competing with scientific theories. 2. Modern science still presupposes causal notions. - Even when speaking in terms of fields, interactions, and laws, science assumes that certain states of affairs bring about others. You do not escape metaphysics by doing physics; you simply rely on it implicitly. 3. The question “why is there any caused reality at all?” remains. - Regardless of which physical model we adopt (classical, relativistic, quantum), we can still ask: why do any contingent, caused beings exist and continue to exist at all? The Second Way argues that the best explanation is a first, uncaused cause that sustains everything else.

Third Way – From Contingency

(P1) There are contingent beings in the world...things that can exist and can fail to exist. A contingent being is one that does not have to exist; it begins to exist and can cease to exist (e.g., people, animals, stars, planets). We observe that such things come into being and pass away, and so their existence is not necessary.

(P2) If everything were contingent, then at some time nothing would have existed. If every being could fail to exist, then there is no guarantee that something or other would always exist. Given enough “time” or possibilities, there would be a state of affairs in which nothing at all existed.

(P3) If at some time nothing existed, then nothing would exist now. From absolute nothingness, nothing comes. If there were ever a total absence of being, nothing could begin to exist, because there would be nothing with the power to bring anything into existence.

(P4) But something does exist now (including ourselves and the world around us). Our present existence is undeniable. It follows that it cannot be the case that only contingent beings have ever existed.

(C1) Therefore, not all beings are contingent; there must exist at least one necessary being that cannot fail to exist.

(P5) A necessary being either has the cause of its necessity in itself or from another. Either the necessary being’s existence is explained by its own nature (it exists “of itself”), or it is necessary because something else makes it so.

(P6) There cannot be an infinite regress of necessary beings whose necessity is caused by another. An endless chain of beings whose necessary existence is borrowed from earlier beings would never explain why there is any necessary existence at all. There must be a necessary being that has the cause of its necessity in itself and does not derive it from another.

(C2) Therefore, there exists a necessary being that has its necessity in itself and is the cause of the existence of all contingent beings.

(C3) This necessary being is what we call God.

Thomas Aquinas, Summa Theologiae, I, q. 2, a. 3 (“Whether God exists?”) – Third Way. Edward Feser, Five Proofs of the Existence of God. San Francisco: Ignatius Press, 2017.
+ Why can’t the universe itself be the necessary being? Maybe the cosmos just exists necessarily.
1. The observable universe looks contingent, not necessary. - The universe begins, changes, and could have been otherwise (different laws, constants, contents). These are marks of contingency. A necessary being, by contrast, cannot begin, end, or exist in a radically different way. 2. Necessary existence is not just “existing for a long time.” - To be necessary is to exist in all possible circumstances, with no dependence on anything else. Our universe appears finely tuned and law-bound in specific ways that could have failed to obtain. That strongly suggests dependence, not self-explanatory necessity. 3. Aquinas’ argument targets being as such, not just the visible cosmos. - The Third Way is not merely asking why this universe exists, but why any contingent reality exists at all. Saying “the universe just is” does not explain why contingent being exists rather than nothing; it simply pushes the question back a step without answering it.
+ The argument assumes a time when nothing existed. But maybe matter or energy has always existed, so the scenario of ‘nothing’ never happened.
1. The Third Way is not mainly about time, but about dependence. - Aquinas’ point is not “long ago there was nothing,” but that if everything that exists could have failed to exist, then there is no sufficient reason why anything exists at all, now or ever. The issue is metaphysical contingency, not just temporal beginnings. 2. An eternal series of contingent beings is still contingent as a whole. - Even if there were an infinite past with no first moment, an eternal succession of things that each might not have existed would still call for an explanation: why does such a contingent series exist at all, rather than nothing? 3. A necessary being explains why there is always something rather than nothing. - If a necessary being exists, its existence is not conditional or temporary. It is, by nature, “always there” (in whatever sense of “always” applies to a necessary being) and can sustain the existence of contingent beings, whether or not the universe has a beginning in time.
+ The argument seems to assume that every fact must have an explanation (a Principle of Sufficient Reason). But maybe some things, like the existence of the universe, are just brute facts.
1. Denying explanation at the deepest level is a high price to pay. - To say “there just are contingent things, with no reason at all” abandons the very drive toward explanation that undergirds science and rational inquiry. It treats the most fundamental question (“Why anything rather than nothing?”) as uniquely exempt from explanation. 2. The contingency intuition is extremely strong and widely shared. - When we encounter things that begin, change, or could have been otherwise, we naturally seek a cause or reason. The Third Way systematizes this basic intuition. Rejecting it at the foundational level looks ad hoc: we use explanatory principles everywhere else, but suspend them precisely where they challenge naturalism. 3. A necessary being offers a deep and unifying explanation. - Postulating a necessary being that explains the existence of all contingent beings gives us a coherent stopping point in our search for reasons. It does not multiply unexplained brute facts; it reduces them by rooting contingent reality in something self-explanatory.
+ Even if there is a necessary being, that doesn’t prove it is the God of Christianity.
This is correct, and it is not what the Third Way is intended to show on its own. The argument aims to establish the existence of: - At least one necessary being - That exists of itself (not by another) - And causes or explains the existence of all contingent beings From there, Aquinas and other classical theists argue that such a being must be: - Simple (without parts), immutable, eternal, immaterial - The source of all perfections found in creatures - Intellective and volitional (having intellect and will) Those further steps, combined with other arguments (from morality, consciousness, revelation, and history), help identify this necessary being more specifically with the God of the Bible. The Third Way supplies one crucial piece of that cumulative case: that contingent reality depends ultimately on a necessary, self-existent source.

Fourth Way – From Degrees of Perfection

(P1) Among things, we find degrees of perfection (more or less good, true, noble, etc.). We naturally compare things in terms of value and excellence: some actions are better than others; some people are wiser, more just, or more loving than others; some beings have fuller reality or goodness than others (e.g., a rational person vs. a rock).

(P2) Degrees of a quality (like goodness or truth) are understood by comparison to a maximum or standard of that quality. When we say one thing is “hotter” or “colder,” “truer” or “better,” we implicitly measure it against some maximum or fullest instance. Aquinas (drawing on Aristotle) holds that gradations in a transcendental property (goodness, truth, nobility) imply a reference to something that possesses that property fully or maximally.

(P3) Therefore, if there are degrees of goodness, truth, and nobility in things, there must be something that is maximally good, maximally true, and maximally noble. This “maximum” is not just a useful fiction or idealization, but a real standard in terms of which all lesser participations in goodness and truth are measured and made intelligible.

(P4) What is maximally true and good is the cause of all that is true and good in other things. Aquinas argues that in any genus, the maximum is the cause of the others in that genus (e.g., the hottest thing is the cause of heat in other things). By analogy, the supreme source of goodness and truth causes and sustains all finite instances of goodness and truth.

(C1) Therefore, there exists something that is the maximum and source of all perfections such as goodness, truth, and nobility in things.

(C2) This maximally perfect being is what we call God.

Thomas Aquinas, Summa Theologiae, I, q. 2, a. 3 (“Whether God exists?”) – Fourth Way. Edward Feser, Aquinas. Oxford: Oneworld, 2009.
+ We can talk about “more” or “less” good, true, or noble without there being a real, existing maximum. It’s just a way of speaking.
1. Comparisons presuppose some standard, even if implicit. - Saying “A is better than B” is not like saying “I prefer A to B.” It implies that A more fully realizes some standard of goodness than B does. Aquinas takes seriously that when we talk about degrees of transcendental properties (goodness, truth, nobility), we are implicitly referencing something like a standard or measure. 2. The question is whether that standard is merely conceptual or also real. - We might treat “perfect goodness” as a mere idealization in our minds, but Aquinas argues that finite, imperfect instances of a perfection are best explained as participating in or imitating a most perfect source in reality, not merely in thought. 3. A purely subjective standard does not fit how we treat value judgments. - Our moral and value judgments typically aim at something objective (e.g., that justice and love are really better than cruelty and hatred). If all standards are just subjective constructs, then the language of “more perfect” loses its deeper, objective force.
+ Just because you can have a maximum in some cases (like temperature) doesn’t mean there is a maximum for every quality, especially something abstract like goodness.
1. Aquinas uses physical examples as analogies, not strict models. - When Aquinas mentions things like heat having a “hottest,” he is illustrating a general metaphysical pattern: degrees of a perfection point to a source in which that perfection is found in the highest way. The core idea is not tied to chemistry or thermodynamics. 2. Some properties are by nature gradable toward an intrinsic maximum. - For many perfections (e.g., knowledge, power, moral goodness), we can meaningfully talk about “more” or “less” in a way that suggests a conceivable completion or fullness of that quality. Infinite wisdom or perfect goodness are natural limiting cases of the scales we already use. 3. The argument concerns transcendental perfections, not arbitrary predicates. - Aquinas is not claiming there is a “maximum number of leaves” or “maximum height” in the same sense. He is focusing on perfections that are convertible with being itself...goodness, truth, nobility of being...which are naturally linked to the very nature of reality and thus to a highest instance.
+ This looks like a sneaky ontological argument: moving from a concept of maximal goodness to the existence of a maximally good being.
1. The starting point is empirical, not purely conceptual. - Unlike a pure ontological argument, the Fourth Way begins with observed facts about the world: we actually encounter things that are more or less good, true, and noble. It is an argument from experience, not merely from a definition. 2. The move is from finite instances to a real explanatory source. - Aquinas is reasoning: given that such perfections are instantiated to varying degrees, the best explanation is that there is a supreme source in which they exist fully and from which they flow, rather than that they are brute, scattered features of an ultimately value-neutral reality. 3. It fits within Aquinas’ broader metaphysical framework. - In Aquinas’ thought, goodness and being are closely related (to be is to be good in some way). Degrees of goodness thus reflect degrees of participation in being itself. A most perfect being, then, is also the most fully real and the source of all other beings...a conclusion that overlaps with, but is not identical to, an ontological-style argument.
+ Even if there is a maximally perfect being, this doesn’t show that it is the God of the Bible.
This is correct, and it is not what the Fourth Way is meant to establish on its own. The argument aims to show that: - There is a supreme source of all perfections found in creatures (goodness, truth, nobility). - This source exists in a wholly maximal way...without defect or limitation. From there, Aquinas and other classical theists argue that such a being must: - Be identical with its own goodness and being (absolutely simple). - Be immutable, eternal, and immaterial. - Possess intellect and will (since goodness and truth are intimately tied to knowledge and love). Those further steps, together with other arguments (cosmological, moral, teleological, historical), help identify this maximally perfect source with the God revealed in Scripture. The Fourth Way contributes the specific insight that the value-structure of reality...its gradations of goodness and truth...points to a supreme, perfect foundation in God.

Fifth Way – From Finality / Teleology

(P1) Non-rational things in nature regularly act for an end (toward goals or purposes). Aquinas notes that natural objects and processes...like acorns becoming oak trees, hearts pumping blood, planets following stable paths, and physical laws yielding orderly outcomes...consistently behave in ways that tend toward certain effects rather than others. They exhibit regular, goal-directed behavior.

(P2) Whatever lacks knowledge cannot direct itself to an end unless it is directed by something with knowledge and intelligence. An arrow does not fly toward a target by itself; it is aimed by an archer. Likewise, entities that have no awareness or understanding (e.g., physical particles, plants, organs) cannot by themselves “aim” at ends. Their consistent tendency toward certain outcomes calls for explanation in terms of an ordering intelligence.

(C1) Therefore, natural things that lack knowledge and yet act for an end must be directed by some being endowed with knowledge and intelligence.

(C2) This intelligent director of nature is what we call God.

Thomas Aquinas, Summa Theologiae, I, q. 2, a. 3 (“Whether God exists?”) – Fifth Way. Edward Feser, Aquinas. Oxford: Oneworld, 2009. Edward Feser, Five Proofs of the Existence of God. San Francisco: Ignatius Press, 2017.
+ This sounds like William Paley’s watchmaker argument. Modern evolutionary biology has already answered that kind of design argument.
1. Aquinas’ Fifth Way is not the same as Paley’s argument from complex organs. - Paley focused on the intricate structure of particular biological systems (like the eye) and argued by analogy to human artifacts. Aquinas is instead interested in the universal fact that non-rational things act in regular, goal-directed ways according to stable laws. 2. The Fifth Way is about final causes built into nature itself. - Aquinas is not merely pointing to complex “designs” and saying “this looks designed.” He is arguing that the very fact that things reliably behave “for an end” (acorns reliably become oaks, electrons reliably behave in lawlike ways, etc.) presupposes an ordering intellect behind the system as a whole. 3. Evolution presupposes, rather than removes, the relevant teleology. - Evolutionary processes themselves rely on deeply structured biological and physical regularities (genetic replication, natural selection, environmental constraints). These regularities are part of the teleological order Aquinas is highlighting. Explaining some biological patterns by evolution does not explain why the larger natural order exhibits the directedness that makes evolution possible.
+ We don’t need God to explain why things behave in regular ways; that’s just what the laws of nature say. They do the explaining.
1. Laws describe regularities; they don’t explain why they exist or hold. - Saying “objects fall because of gravity” or “electrons behave this way because of quantum laws” tells us how things behave, not why there are such lawlike tendencies at all, or why they are ordered toward specific ends rather than chaos. 2. The very existence of stable, mathematically expressible laws is part of what needs explanation. - The fact that the universe is not a random chaos of events, but a deeply ordered system where entities consistently “aim” at certain effects (e.g., stable orbits, reliable chemical reactions), fits naturally with Aquinas’ claim that an intelligent cause orders things to their ends. 3. The Fifth Way is compatible with and deeper than scientific laws. - Aquinas is not proposing a rival to physics or chemistry. He is offering a metaphysical explanation of why there is a teleological order that physics can successfully describe in the first place. Laws are the “how”; the Fifth Way addresses the “why” of that lawful, end-directed structure.
+ Nature includes randomness, chaos, and failures (e.g., genetic defects, natural disasters). Doesn’t that undercut the idea that everything is ordered toward an end by an intelligent designer?
1. The existence of chance events presupposes an ordered background. - “Random” or “chaotic” in science typically means “unpredictable within a given model,” not “lawless at the deepest level.” Chance events still occur within a larger framework of stable laws and tendencies...the very framework the Fifth Way is about. 2. Teleology is about general tendencies, not perfection in every case. - Saying an acorn is directed toward becoming an oak does not mean every acorn succeeds (some are eaten, rot, or fail). Likewise, organs can malfunction, and natural processes can misfire, without negating the general, goal-directed pattern they usually display. 3. The problem of natural evil is a separate question. - The Fifth Way aims to show that there is an ordering intelligence behind the teleological structure of nature. Questions about why God allows defects, suffering, or natural disasters belong to the problem of evil, which must be addressed by additional theological and philosophical considerations, not by denying the underlying order the argument focuses on.
+ Even if there is some intelligence behind nature, that doesn’t mean it is the personal God of Christianity.
This is correct, and Aquinas would agree that the Fifth Way by itself does not establish every attribute of the Christian God. What it does aim to show is that: - There is an intelligent cause that orders non-rational nature to its ends. - This intelligence operates at the most fundamental level of reality, not as a tinkering “god of the gaps.” From there, Aquinas and other classical theists argue further that: - The intelligent director of all natural ends must be simple, necessary, eternal, and immaterial. - Such a being must have intellect and will in the highest, most perfect way. - Combined with other arguments (from motion, causation, contingency, moral law, and revelation), this intelligent source is best identified with the God revealed in Scripture. Thus the Fifth Way contributes a specific insight: the pervasive goal-directedness of nature is not an accident, but points beyond the cosmos to a supreme ordering Mind.

Christian Evidences

Evidence & Arguments for Christian Theism

Resurrection of Jesus

Evidence for the Resurrection of Christ

Three Facts Argument

(P1) Fact 1: Jesus’ tomb was discovered empty shortly after His crucifixion. Multiple early, independent sources report that Jesus’ tomb was found empty. The earliest Christian preaching in Jerusalem presupposes that the body was no longer in the grave. Women are presented as the first discoverers of the empty tomb, which is an unlikely fabrication in a first-century Jewish context where female testimony carried low legal weight. In addition, the earliest Jewish polemic (“the disciples stole the body”) presupposes that the tomb was, in fact, empty, rather than still containing Jesus’ corpse.

(P2) Fact 2: Various individuals and groups experienced appearances of Jesus alive after His death. The early creed cited by Paul in 1 Corinthians 15:3–7 (usually dated within a few years of the crucifixion) lists appearances to Peter, the Twelve, more than 500 at one time, James, “all the apostles,” and Paul himself. The Gospels independently attest to appearances in different locations and settings (e.g., in Jerusalem, on the road to Emmaus, by the Sea of Galilee). Critical scholars across the spectrum generally agree that these individuals and groups had real experiences which they took to be encounters with the risen Jesus.

(P3) Fact 3: The original disciples came to be firmly and sincerely convinced that God had raised Jesus bodily from the dead. After Jesus’ crucifixion, the disciples were discouraged, fearful, and in hiding. As first-century Jews, they did not expect a crucified Messiah, nor did they expect an isolated resurrection within history. Yet very soon they began boldly proclaiming that God had raised Jesus from the dead and had exalted Him as Lord. Many of them willingly endured persecution, suffering, and for some, martyrdom, without historical evidence of recanting. In addition, skeptics and opponents such as James (Jesus’ brother) and Paul (a persecutor of Christians) were transformed into convinced proclaimers of the risen Christ.

(P4) No naturalistic hypothesis (conspiracy, apparent death, hallucination, displaced body, or legend) adequately explains these three facts taken together. Through the history of scholarship, a range of naturalistic explanations have been proposed: that the disciples stole the body, that Jesus only appeared to die, that the appearances were hallucinations or visions, that the body was moved or misplaced, or that resurrection stories arose as legend. Each of these theories faces serious difficulties when judged against the empty tomb, the broad pattern of appearances, and the radical, early, resurrection-centered conviction of the disciples. Contemporary specialists rarely defend these hypotheses as fully adequate explanations of the core historical data.

(C) Therefore, the best explanation of the empty tomb, the post-mortem appearances, and the disciples’ sincere, early belief is that God raised Jesus bodily from the dead.

Craig, William Lane. Assessing the New Testament Evidence for the Historicity of the Resurrection of Jesus. Revised edition. Eugene, OR: Wipf & Stock, 2024.
+ Maybe the disciples stole Jesus’ body and knowingly lied about the resurrection.
See argument: Contra Conspiracy Hypothesis. In brief, this view conflicts with first-century Jewish expectations, fails to account for the disciples’ willingness to suffer and die for their message, and does not fit the psychologically realistic and often embarrassing nature of the early testimonies.
+ Maybe Jesus never truly died but merely swooned and later revived in the tomb.
See argument: Contra Apparent Death Hypothesis. Historically and medically, Roman crucifixion procedures, Jesus’ severe scourging and spear wound, and the conditions of burial make survival extremely implausible. Even if He had survived, a half-dead, badly injured man would not plausibly generate belief in a glorious, victorious resurrection.
+ Maybe the disciples and others simply hallucinated or had visionary experiences of Jesus.
See argument: Contra Hallucination Hypothesis. The resurrection appearances are multiple, involve groups and skeptics, occur in various places and times, and are tightly linked with the claim that the tomb was empty. This pattern does not match what we know of hallucinations, which are typically private, individual, and do not explain a missing body.
+ Maybe Jesus’ body was moved to another location, and the empty tomb was a misunderstanding.
See argument: Contra Displaced Body Hypothesis. Jewish burial customs, Joseph of Arimathea’s role, and the location of alternative burial sites make this unlikely. If the body had simply been relocated, the authorities or Joseph himself could have corrected the disciples once resurrection was preached, by producing or identifying the corpse.
+ Maybe the resurrection accounts slowly developed as legends over time.
See argument: Contra Legend Hypothesis. The core resurrection proclamation appears in very early traditions (such as the 1 Corinthians 15 creed), within a short time after the events and while many eyewitnesses were still alive. The Gospels show restraint compared to later apocryphal writings and preserve embarrassing, non-idealized features, which do not fit well with a late, purely legendary development.

Maximal Facts Argument

(P1) The New Testament documents are multiple, early, independent, and generally reliable historical sources about Jesus and the earliest Christian movement. On a “maximal data” approach, we do not artificially restrict ourselves to a handful of widely conceded facts; rather, we assess the New Testament writings as we would other ancient historical sources. The Gospels and Acts show: (1) multiple authors drawing on distinct sources and traditions, (2) early composition within living memory of the events, (3) familiarity with first-century Palestinian geography, customs, and politics, and (4) undesigned coincidences between different books that mutually confirm their historical character. This justifies treating them as broadly trustworthy witnesses, not as late, legendary compilations whose details must be discarded in advance. See also: • NT Criticism: Undesigned Coincidences as Evidence of Gospel Reliability • NT Criticism: External Corroboration – Archaeology and Non-Christian Sources • NT Criticism: Early Dating and Eyewitness Proximity of the New Testament

(P2) Taken as generally reliable, these sources support a rich cluster of historical facts about Jesus’ death, burial, empty tomb, and post-mortem appearances. Among the facts supported by the Gospels, Acts, and Paul’s letters are: (a) Jesus’ public ministry, arrest, and condemnation under Pontius Pilate; (b) His brutal scourging and crucifixion, leading to His death; (c) His burial in a specific rock-hewn tomb belonging to Joseph of Arimathea; (d) the discovery of His tomb empty early on the first day of the week by a group of His female followers; (e) multiple, extended, sensory encounters with Jesus alive again, at different times and places, involving different individuals and groups (including meals, conversations, and physical contact); (f) the transformation of the disciples from fearful and despondent to bold public witnesses; and (g) the conversions of prominent skeptics and opponents such as James and Paul, grounded in what they took to be encounters with the risen Christ. See also: • NT Criticism: Internal Marks of Eyewitness Testimony and Verisimilitude • NT Criticism: Convergence of Independent New Testament Traditions • NT Criticism: Transformation and Conduct of the Key Witnesses

(P3) These facts are supported not only by Christian testimony but also by undesigned coincidences, external corroboration, and hostile or neutral sources that confirm key points. Undesigned coincidences...subtle interlocking details between different New Testament documents...show that the authors are independently reporting a shared underlying reality rather than colluding in fiction. For example, incidental details in one Gospel explain obscure statements in another without apparent design. In addition, non-Christian sources (such as Tacitus, Josephus in at least some textual layers, and early hostile traditions) affirm that Jesus was crucified under Pilate, that His followers quickly proclaimed His resurrection, and that the movement spread despite persecution. Jewish polemic presupposes that the tomb was empty, accusing the disciples of stealing the body rather than simply pointing to a known, occupied grave. See also: • NT Criticism: Undesigned Coincidences as Evidence of Gospel Reliability • NT Criticism: External Corroboration – Archaeology and Non-Christian Sources

(P4) No naturalistic explanation (fraud, apparent death, hallucination, displaced body, legend, or any combination thereof) adequately accounts for this broad, interconnected body of evidence when the New Testament is treated with ordinary historical seriousness. When the full range of data is considered...Jesus’ known death by crucifixion, specific tomb burial, empty tomb discovered by named individuals, numerous multi-sensory appearances over forty days, the radical and immediate transformation of the disciples, the conversions of James and Paul, the detailed and realistic character of the narratives, and the deep internal coherence across independent documents...naturalistic theories repeatedly fail. Each tends to explain at best one or two elements while contradicting others or requiring ad hoc additions. A conspiracy cannot plausibly sustain decades of suffering and martyrdom; a swoon does not fit Roman execution practices or inspire worship of a glorified, death-conquering Lord; hallucinations do not produce an empty tomb, coordinated group appearances, and conversions of enemies; displaced body and legend theories conflict with early, structured tradition and eyewitness-rooted testimony. Combining them only multiplies speculative assumptions without yielding a simple, unified account. See also: • Resurrection: Contra Conspiracy Hypothesis (Stolen-Body Theory) • Resurrection: Contra Apparent Death Hypothesis (Swoon Theory) • Resurrection: Contra Hallucination Hypothesis • Resurrection: Contra Displaced Body Hypothesis • Resurrection: Contra Legend Hypothesis

(P5) If God exists and has reason to vindicate Jesus’ claims and mission, then a bodily resurrection fits naturally as a divine action in history and provides a powerful, unified explanation of all the maximal facts. Philosophical arguments for the existence of God (cosmological, teleological, moral, and more) make divine action a live explanatory option. On that background, the hypothesis that God raised Jesus from the dead is not an arbitrary miracle claim but a theologically fitting act: it vindicates Jesus’ messianic claims, confirms His teaching, and inaugurates the new covenant and the hope of final resurrection. This single hypothesis straightforwardly explains the empty tomb, the varied and persistent appearances, the transformation of frightened disciples into bold witnesses, the conversions of skeptics and opponents, and the rise and spread of the early Christian movement centered on the proclamation that “God has Him from the dead.” See also: • Natural Theology Arguments

(C) Therefore, when we consider the maximal range of well-supported historical data and treat the New Testament documents as generally reliable sources, the best explanation is that God raised Jesus bodily from the dead.

+ The maximal facts argument simply grants that the New Testament is generally reliable, which is exactly what skeptics dispute. This stacks the deck in favor of resurrection.
1. The reliability claim is argued for, not merely assumed. Defenders of the maximal facts approach (such as Lydia and Tim McGrew) present detailed positive arguments for the historical trustworthiness of the New Testament: undesigned coincidences, accurate incidental details, correct geographical and cultural references, and coherence with external evidence. The argument invites us to treat these documents by the same standards we use for other ancient sources. 2. General reliability does not mean inerrancy or perfection. The maximal approach does not require that every verse be error-free to use the documents historically. Historians routinely regard ancient works as generally reliable while allowing for minor mistakes or uncertainties. The question is whether the New Testament, overall, has the marks of honest reporting about real events...and the McGrews argue that it does. 3. Skeptics are free to challenge particular details, but must then offer an alternative explanation of the cumulative pattern. Even if someone disputes one or two elements, the larger body of interlocking facts, supported by multiple lines of evidence, still stands in need of explanation. The maximal facts approach is powerful precisely because it does not rest on a single verse or isolated claim but on a broad, interconnected network of data. See also: • NT Criticism: Undesigned Coincidences as Evidence of Gospel Reliability • NT Criticism: External Corroboration – Archaeology and Non-Christian Sources • NT Criticism: Early Dating and Eyewitness Proximity of the New Testament
+ People in the ancient world were generally superstitious and uncritical. We should not put much stock in their miracle reports, including resurrection claims.
1. The New Testament authors often show critical awareness of alternative explanations. The Gospels and Acts mention attempts to explain away miracles (e.g., accusations of demonic power, claims that the disciples stole the body, doubts within the ranks of the disciples themselves). They record skepticism and verification behaviors (touching, eating, extended conversations) rather than blind acceptance. 2. Intellectual ability and critical reasoning are not modern inventions. Ancient historians, philosophers, and legal writers display sophisticated reasoning and awareness of human error. First-century Jews and Greeks knew that dead people stay dead; that is why resurrection, when claimed, was so controversial. The very scandal of the resurrection message argues against a background of uncritical gullibility. 3. Credulity in some areas does not invalidate all testimony. Modern people can be gullible too, yet we still rely on eyewitness reports in courts, journalism, and everyday life. The question is not whether ancient people ever believed foolish things, but whether specific witnesses in specific contexts give us good reason to trust them about specific events...especially when multiple, independent, mutually reinforcing testimonies are available. See also: • NT Criticism: Internal Marks of Eyewitness Testimony and Verisimilitude • NT Criticism: Transformation and Conduct of the Key Witnesses
+ The Gospel accounts of the resurrection contain apparent contradictions. If they cannot even agree on basic details, we should not build a maximal argument on them.
1. Many alleged contradictions dissolve on closer examination. Differences in emphasis, compression, or selection of details can look like contradictions at first glance but can often be plausibly harmonized. Defenders of the McGrews’ approach offer specific case studies showing how various accounts fit together like different camera angles on the same events. 2. Variation in secondary details is exactly what we expect from independent witnesses. In ordinary historical and legal contexts, slight divergences in detail are a mark of genuine, independent testimony, not collusion. A perfectly uniform set of stories would raise suspicion of fabrication. The Gospels’ differences, set against their deep underlying agreement, look more like authentic multiple attestation than like sloppy legend. 3. The core claims remain stable and mutually reinforcing. All four Gospels attest to Jesus’ crucifixion under Pilate, His burial, the empty tomb discovered on the first day of the week, and subsequent appearances to followers. The maximal facts argument focuses on this robust center of agreement, supported by multiple authors and traditions, not on every disputed peripheral detail. See also: • NT Criticism: Convergence of Independent New Testament Traditions • NT Criticism: Early Dating and Eyewitness Proximity of the New Testament
+ Appealing to a miracle to explain a large collection of facts is still a ‘God of the gaps’ move, just with more gaps described in detail.
1. The maximal facts argument appeals to explanatory power, not to ignorance. “God of the gaps” arguments say, “We do not know how this happened, therefore God did it.” By contrast, the maximal facts approach compares specific naturalistic hypotheses with the resurrection hypothesis and asks which best explains the positive evidence we have. It is a competition of explanations, not a retreat into mystery. 2. The resurrection hypothesis makes positive, testable predictions about the kind of evidence we should expect. If God raised Jesus, we would anticipate an empty tomb, persistent and transformative appearances, early and bold proclamation centered on resurrection, and documents that bear marks of honest testimony. That is exactly the pattern we find. This is not plugging God into a gap but recognizing a theistic explanation that fits the evidence better than its rivals. 3. The argument is framed within a broader theistic context. If we already have independent reasons to believe that God exists, then divine action is not an ad hoc way to patch holes, but a live explanatory option. The resurrection is then assessed as a particular historical claim about what this God has done, rather than as a last-ditch resort when natural causes fail. See also: • Natural Theology Arguments
+ Because the maximal facts argument is cumulative, a skeptic can always resist it by denying enough individual premises or casting doubt on enough details.
1. Logical possibility of resistance is different from rational plausibility. In principle, anyone can deny any premise. The important question is whether such denials are well-motivated and supported by evidence, or whether they are ad hoc moves to avoid an unwelcome conclusion. A cumulative case gains force when each individual premise is independently credible and the overall pattern is hard to dismiss without special pleading. 2. The facts used in the maximal case are diverse and mutually reinforcing. The argument does not lean on a single fragile point. Archaeological realism, undesigned coincidences, early creedal material, external references, internal coherence, and psychological transformation all converge. To dismantle the case, one must undermine many different kinds of evidence, which is far more difficult than raising doubts about a single datum. 3. Cumulative reasoning is standard and appropriate in historical and legal contexts. Courts, historians, and everyday reasoning often rely on the convergence of many small indicators rather than on a single overwhelming proof. The maximal facts argument applies this ordinary pattern of reasoning to the question of Jesus’ resurrection, inviting fair-minded evaluation rather than demanding blind acceptance.

Contra Conspiracy Hypothesis (Stolen-Body Theory)

(P1) The conspiracy hypothesis claims that the disciples knowingly lied by stealing Jesus’ body and fabricating resurrection appearances. According to this view, the core witnesses to the resurrection did not sincerely believe that God had raised Jesus. Instead, they deliberately removed His corpse from the tomb and then proclaimed that He had risen, inventing stories of appearances they knew were false. The hypothesis thus rests on intentional deception by the earliest Christian leaders about the central claim of their faith.

(P2) First-century Jewish expectations and the disciples’ post-crucifixion condition make such a deliberate resurrection hoax highly implausible. As first-century Jews, the disciples did not expect a crucified and cursed Messiah to be vindicated by resurrection within history. A shameful Roman execution signaled divine rejection, not victory. Their belief in resurrection concerned a general raising of the dead at the end of the age, not an isolated event involving the Messiah. After Jesus’ death, they were discouraged, fearful, and in hiding. Under these conditions, the intentional creation of a radical, theologically novel resurrection hoax is historically and psychologically unlikely.

(P3) The disciples’ sustained willingness to suffer and die for the resurrection message strongly supports their sincerity rather than a conscious lie. From the earliest centuries, Christian sources and external testimony converge in depicting the apostles as facing persecution, imprisonment, hardship, and, in several cases, martyrdom for proclaiming the risen Christ. People will sometimes die for beliefs that are false but sincerely held; it is far more difficult to explain a group of conspirators enduring severe suffering for a claim they themselves invented and knew to be false, especially over many years and across diverse regions, without evidence of recantation that exposes the plot.

(P4) The character of the early resurrection testimony fits honest, sometimes embarrassing witness, not a carefully crafted piece of propaganda. The Gospels and early preaching include numerous features that are awkward or counterproductive if the aim were to promote a calculated hoax: women as the first discoverers of the empty tomb; the cowardice, doubts, and failures of leading disciples (including Peter’s denial); and the slowness of the apostles themselves to believe the resurrection reports. Such elements are more naturally explained as the candid memory of a community preserving what actually happened, rather than as the polished product of a conspiracy seeking power or prestige.

(C) Therefore, the conspiracy / stolen-body hypothesis is not a credible explanation of the empty tomb, the resurrection appearances, or the rise of the disciples’ resurrection-centered faith.

+ Religious leaders sometimes lie for power, wealth, or influence. The apostles could have done the same.
1. The apostles’ historical pattern is one of sacrifice and loss, not worldly gain. The earliest Christian witnesses face hostility and hardship: imprisonment, beatings, exile, and often death. They do not acquire palaces, armies, or political office. Their ministry involves physical danger, poverty, and service, which is the opposite of what religious frauds typically seek if their goal is power or luxury. 2. The message they preached is not tailored for easy popularity. The proclamation of a crucified Messiah was a “stumbling block” to Jews and “foolishness” to many Gentiles. The call to repentance, self-denial, sexual purity, and love of enemies is demanding and costly. If they were inventing a religion for self-advantage, they chose an unusually offensive and sacrificial message. 3. Dying for a known lie across an entire core group is psychologically implausible. Individuals sometimes persist in lies when they benefit, but a whole inner circle continuing to affirm what they know is false, over many years and under persecution, without credible evidence of any leader exposing the fraud to save himself, is extremely difficult to explain. The pattern of their lives fits sincerity far better than calculated deception.
+ Perhaps the disciples, in grief and panic, stole the body first, and only later rationalized and solidified a resurrection story around what they had done.
1. Their theological expectations do not naturally lead to inventing a bodily resurrection. As Jews, the disciples expected a powerful, triumphant Messiah and a general resurrection at the end of history. After a shameful crucifixion, the more natural response would have been to admit they were mistaken about Jesus or to honor Him as a martyred prophet, not to claim that He had already been bodily raised in the middle of history. 2. The narrative of the disciples after the crucifixion is one of fear and retreat, not bold planning. The earliest accounts depict the disciples as scattered, hiding, and afraid. Organizing a tomb robbery under the watch of hostile religious authorities and, possibly, Roman guards would require courage and coordination these same sources say they lacked at that point. 3. A rash act does not explain decades of unified, costly proclamation. Even if some impulsive theft had occurred, it does not explain why, over time, none of the core participants confessed the original deed, even under pressure. The long-term, consistent, and public preaching of the resurrection across different regions is better accounted for by genuine conviction rather than a story invented after an ill-considered theft.
+ Other religious movements may have originated in deception or fraud. Christianity could simply be another example.
1. Pointing to possible fraud elsewhere does not establish fraud here. The fact that some leaders in history have lied does not show that the apostles did. One must examine the specific historical context, evidence, and character of the early Christian movement, rather than assuming guilt by analogy. 2. The apostolic pattern differs from classic cases of exploitative founders. Known charlatans often accumulate wealth, control, and moral exceptions for themselves. By contrast, the apostles preach humility, personal holiness, and sacrificial love, and they live under these demands themselves, even at great personal cost. Their own conduct argues against a cynical, self-serving plot. 3. The resurrection claim is anchored in public events in a hostile environment. The disciples proclaim the resurrection in Jerusalem, where Jesus had been publicly executed and where authorities were strongly motivated to suppress the movement. Fraudulent claims about a missing body and public appearances would have been easier to expose there than in some distant, inaccessible place. The survival and growth of the movement in that setting favors sincerity, not invention.
+ Instead of a calculated plot, the disciples might have gradually convinced themselves of a story they originally knew was doubtful, blurring the line between lie and belief.
1. This shifts the explanation away from true conspiracy to something like legend or psychological error. If the disciples no longer knowingly lie but sincerely misremember or reinterpret events, that is no longer the conspiracy hypothesis. It becomes closer to the legend hypothesis or a kind of psychological theory of self-deception, which must be evaluated on its own merits. 2. The time frame for such drift is too short given the early, fixed core of the resurrection proclamation. Key resurrection traditions, such as the creed in 1 Corinthians 15:3–7, arise within a few years of the events, already listing a structured set of appearances and proclaiming bodily resurrection. This does not look like a slow, hazy evolution of memory decades later; it looks like a quick, confident, and widely shared claim. 3. Group self-deception does not explain the empty tomb and the convergence of independent witnesses. To maintain that all core witnesses gradually talked themselves into believing a resurrection that never happened, while also explaining away the empty tomb and the variety of appearance traditions, requires a complex and speculative psychological story. A straightforward reading...that they testified to what they took to be real encounters with the risen Jesus...is simpler and fits better with the data.
+ Perhaps a small subgroup faked the empty tomb while others, not part of the deception, had real visions or experiences they took as confirmation.
1. This multiplies ad hoc elements and splits the explanation without textual support. Now we must posit at least two kinds of actors: deliberate deceivers who manipulate the tomb and sincere experiencers who are unaware of the deception, plus a process by which all of this coheres into a unified proclamation. The historical sources, however, present the apostolic group as united in testimony, not divided into liars and dupes. 2. Early proclamation tightly interweaves the empty tomb and bodily appearances. The New Testament preaching and narratives link the empty tomb and the appearances into a single theological claim: “He is not here; He has risen.” They do not suggest that some leaders focused solely on a missing body while others independently had unrelated visionary experiences. The story is woven together from the start. 3. Combining partial fraud with partial hallucination or error is less plausible than a single, coherent explanation. A hybrid theory that invokes some conspirators, some hallucinations, and some misunderstandings quickly becomes complex and speculative. The unifying explanation that the disciples encountered the risen Jesus and reported what they believed they had experienced is historically simpler and more satisfying than a patchwork of partial frauds and partial psychological phenomena.

Contra Apparent Death Hypothesis (Swoon Theory)

(P1) Given Roman execution practices and Jesus’ recorded condition, survival of crucifixion and burial is historically and medically implausible. Roman soldiers were professional executioners whose duty was to ensure that crucified victims were dead before removal from the cross. Jesus was severely scourged, nailed to the cross, left to asphyxiate, and then pierced in the side, which the Gospel of John reports as producing a flow of blood and water. Even many critical scholars concede that, in light of these factors, Jesus truly died on the cross rather than merely appearing to die.

(P2) Even if Jesus had somehow survived crucifixion, His post-crucifixion condition would not have generated belief in a glorious, victorious resurrection. A man who had barely escaped death by crucifixion would have been gravely wounded, weak, and in need of urgent medical care. Limping out of a tomb, bleeding and traumatized, He would have elicited pity and the hope of recovery, not the conviction that He had conquered death in a transformed, immortal state. The disciples’ proclamation that Jesus was the risen Lord and conqueror of death does not match what a half-dead survivor would reasonably inspire.

(P3) Logistical and environmental factors surrounding Jesus’ burial further undermine the survival scenario. The burial accounts describe Jesus being wrapped in linen, laid in a rock-hewn tomb, and the entrance being closed with a heavy stone. In at least some accounts, guards are posted. A man in Jesus’ condition would have had to regain consciousness unaided, free Himself from grave clothes, move the stone from the inside, possibly evade or overpower guards, and then travel to meet His followers...all without medical treatment, food, or water in a short span of time. This combination of feats strains plausibility given His prior torture and execution.

(P4) Because of these difficulties, the apparent death hypothesis is almost universally rejected by contemporary New Testament historians and medical commentators on crucifixion. While the swoon theory enjoyed some popularity in earlier centuries, modern discussions of Roman crucifixion procedures, combined with historical-critical studies of the passion narratives, have led most scholars...across a broad spectrum of views on the resurrection...to dismiss it as a viable explanation. It is seen as ad hoc, medically implausible, and out of step with what we know about Roman executions and burial practices.

(C) Therefore, the apparent death / swoon hypothesis is not a credible explanation of the empty tomb, the resurrection appearances, or the disciples’ robust belief that Jesus had been bodily raised from the dead.

Craig, William Lane. Assessing the New Testament Evidence for the Historicity of the Resurrection of Jesus. Revised edition. Eugene, OR: Wipf & Stock, 2024. Gary Habermas and Michael Licona, The Case for the Resurrection of Jesus. Grand Rapids: Kregel, 2004.
+ Roman soldiers sometimes made mistakes. It is possible they thought Jesus was dead when in fact He was only unconscious.
1. Professional executioners had strong practical incentives to ensure death. Roman soldiers tasked with crucifixion had extensive experience and were subject to severe penalties if a condemned criminal survived. Their job was not to guess but to make certain the execution was complete. It is historically unlikely that they would remove a victim they merely suspected to be dead. 2. The reported spear thrust provides an additional check on Jesus’ death. The Gospel of John describes a soldier piercing Jesus’ side with a spear, producing a flow of blood and water...a detail often interpreted as consistent with a fatal wound to the chest cavity. Even if one questions John’s theological motives, the inclusion of such a specific, bodily detail is aimed at underlining that Jesus was truly dead, not merely unconscious. 3. A rare theoretical possibility does not outweigh the combined force of the historical and medical evidence. While absolute logical impossibility is not claimed, the historical question is what is most probable given Roman practice, the nature of crucifixion, and the specific narrative details. On that level, survival is extremely unlikely and not a reasonable basis for explaining the origin of the Easter faith.
+ People have been known to survive extreme injuries and recover unexpectedly. Jesus could have been one such extraordinary case.
1. Extraordinary modern recoveries typically involve medical care and supportive conditions. Survivors of severe trauma today usually benefit from surgery, transfusions, sterile environments, and intensive aftercare. Jesus, by contrast, would have been left in a cold, dark tomb, wrapped in linen, without food, water, or medical attention. 2. The scenario requires not just survival but extraordinary physical capability soon afterward. The apparent death hypothesis asks us to believe that Jesus, after surviving scourging, crucifixion, and a spear wound, not only revived but had enough strength to free Himself from grave clothes, move a heavy stone, potentially evade guards, and then travel to meet and speak with His followers. This is far more demanding than merely “hanging on” in a hospital bed. 3. Even an astonishing survival would not produce the specific resurrection belief we see. At most, such a recovery would support the conclusion that Jesus, though gravely injured, was still mortal and had narrowly escaped death. It would not naturally lead monotheistic Jews to proclaim that He had been raised in glory, conquered death, and inaugurated the general resurrection ahead of time.
+ The cool air and quiet of the tomb could have functioned like a primitive intensive care setting, helping Jesus slowly revive rather than die.
1. The tomb environment lacks the essentials needed for recovery. A rock-hewn tomb provides no medical equipment, no antiseptics, no attendants, and no ready access to food or water. For a man with deep lacerations, nailed extremities, and a spear wound, such an environment would more likely hasten death through shock, blood loss, and infection than facilitate recovery. 2. The physical obstacles remain formidable even if revival occurred. Jesus would still face the problem of moving the blocking stone from inside, managing His grave clothes, and exiting without assistance. If guards were present, He would also need to escape without being apprehended. The tomb’s “quiet” does not remove these concrete difficulties. 3. The theory still does not account for the nature of the disciples’ testimony. The disciples do not simply report seeing a weak, recuperating Jesus; they testify to a risen Lord who appears and disappears, is no longer subject to death, and is exalted by God. A scenario of gradual revival in a tomb cannot naturally be stretched to fit these robust resurrection claims without becoming highly speculative.
+ If Jesus had survived and appeared to His followers in any condition, their emotional attachment could have led them to interpret this as proof that He had risen.
1. The disciples were not expecting a resurrection of this kind. First-century Jewish disciples did not anticipate that their Messiah would be crucified and then individually raised from the dead before the end of the world. After the crucifixion, they are portrayed as demoralized, not as eagerly waiting for Jesus to reappear any way He could. 2. The resurrection claim goes far beyond “He’s alive after all.” The early Christian message is not simply that Jesus somehow survived; it is that God raised Him from the dead, vindicated Him as Lord, and inaugurated the eschatological resurrection in His person. This is a bold theological claim that outstrips mere survival and reflects a conviction that death itself has been decisively overcome. 3. Emotional attachment cannot generate the objective signs claimed, such as the empty tomb and multiple, transformative appearances. Even if strong attachment made the disciples more open to positive interpretations, it does not in itself create an empty tomb, nor does it explain the breadth and character of the appearance traditions, including appearances to skeptics like James and an enemy like Paul.
+ Even if the swoon theory is unlikely, it is still a natural explanation and should be preferred over a miraculous resurrection.
1. An explanation’s mere “naturalness” does not automatically make it the best explanation. Historians aim for explanations that are not only natural but also coherent, simple, and well-supported by the data. A highly contrived natural hypothesis that stretches or ignores the evidence is not automatically superior to a simpler, better-fitting theistic explanation, especially if the existence of God is already supported by independent arguments. 2. The swoon theory is both ad hoc and in tension with multiple lines of evidence. To sustain it, one must posit a long chain of unlikely events: mistaken death pronouncement, survival of extreme trauma without care, escape from a sealed tomb, evasion of guards, rapid physical recovery, and then successful persuasion of followers that He is the conqueror of death. This complexity and improbability work against its being the best-fit explanation. 3. If God exists, a resurrection is not inherently less reasonable than an extremely improbable natural accident. If it is even possible that God exists, then a miracle such as the resurrection is also possible. In that context, historians are justified in considering whether God’s raising Jesus from the dead provides a more unified and less ad hoc explanation of the empty tomb, the appearances, and the disciples’ transformed conviction than the swoon theory does.

Contra Displaced Body Hypothesis

(P1) The displaced body hypothesis claims that Jesus’ body was moved from the original tomb to another location, leading to an honestly mistaken belief in resurrection. On this view, Jesus was initially placed in a convenient, temporary tomb (such as Joseph of Arimathea’s) and later transferred to a different burial place...perhaps a common grave. When some of Jesus’ followers found the first tomb empty and did not know about the transfer, they concluded that God had raised Him from the dead. The hypothesis thus seeks to explain the empty tomb without fraud or miracle, by appeal to an unpublicized relocation of the corpse.

(P2) Jewish burial customs and the specific details of Jesus’ burial make such a quiet, unofficial relocation unlikely. Jewish burial practice in the first century generally discouraged moving a body after interment, except for transferring remains to a family tomb. The Gospels emphasize that Jesus was buried in a new rock-hewn tomb owned by Joseph of Arimathea, which suggests a deliberate and honorable burial, not an improvised, temporary arrangement. If the intention had been to place Jesus in a common grave for criminals, such a grave was likely already available near the execution site, making a detour through Joseph’s tomb unnecessary and implausible as a mere stopgap.

(P3) If Jesus’ body had been relocated, those responsible (especially Joseph or the authorities) could have easily corrected the disciples’ supposed mistake once resurrection was publicly proclaimed. The early Christian message that “God has raised Jesus” was first preached in Jerusalem, the very city where Jesus had been buried. If the body had simply been moved to another known location, Joseph of Arimathea, Jesus’ family, or the Jewish and Roman authorities could, in principle, have identified the new burial site or produced the body. This would have decisively refuted the resurrection proclamation and undercut the nascent Christian movement. The absence of any such counter-demonstration is difficult to reconcile with a simple, known relocation theory.

(P4) The displaced body hypothesis does not account for the breadth and character of the resurrection appearances and the disciples’ transformed conviction. Even if the body had been moved and the first disciples mistakenly assumed resurrection, this would not explain why multiple individuals and groups...some of them initially skeptical...came to have powerful experiences they took to be encounters with the risen Jesus. Nor does it explain why these experiences led to a stable, bold proclamation of bodily resurrection, rather than to confusion and eventual correction once the true location of the body became known or remained discoverable in the surrounding community.

(P5) Because it is speculative, weakly attested, and fails to explain the core data, the displaced body hypothesis has little support among contemporary resurrection scholars. Modern historical and theological discussions of the resurrection rarely rely on the displaced body theory. It lacks direct textual or archaeological support, conflicts with known burial customs, and leaves the appearance traditions and the disciples’ transformed worldview largely untouched. As a result, it is generally regarded as an ad hoc attempt to preserve a purely natural explanation of the empty tomb rather than as a well-grounded historical hypothesis.

(C) Therefore, the displaced body hypothesis is not a plausible or comprehensive explanation of the empty tomb, the resurrection appearances, or the origin of the early Christian resurrection faith.

+ Because of time pressure before the Sabbath, Joseph could have used his tomb only temporarily, intending to move Jesus’ body later.
1. The burial narratives emphasize deliberate honor, not a casual stopgap. The Gospels portray Joseph of Arimathea as intentionally giving Jesus a dignified burial in his own new tomb, with care taken in wrapping the body and sealing the entrance. This suggests a settled arrangement rather than a hurried, makeshift solution that was always meant to be reversed. 2. A common grave for criminals would have been immediately available if desired. If the goal was simply to dispose of the body quickly in view of the Sabbath, burial in a nearby common grave would have been sufficient from the start. Diverting the body into a private, honorific tomb, only to move it again later, introduces an unnecessary and unexplained extra step. 3. The hypothesis requires significant actions by Joseph that the sources neither mention nor imply. The texts never hint that Joseph later planned to remove the body. Introducing this intention is speculative and not grounded in explicit evidence, weakening the displaced body scenario as a historical explanation.
+ Perhaps Jewish law allowed enough flexibility that moving Jesus’ body later would not have been unusual or problematic.
1. The general presumption in Jewish practice was to respect the finality of burial. While there were circumstances under which remains could be transferred (for example, to a family tomb after the flesh had decayed), Jewish tradition did not treat post-burial movement of bodies as a trivial matter. It was typically regulated and tied to family or ritual considerations. 2. The displaced body hypothesis requires a casual, unannounced move rather than a customary, family-based transfer. The theory envisions Joseph or others secretly relocating Jesus’ body in a way that left the disciples completely ignorant. This is different from known, regulated practices and would be at odds with the public significance of Jesus’ execution and burial. 3. Even if movement were theoretically permitted, that does not show it actually happened in this case. Appealing to legal possibility is not the same as providing historical evidence. The question is not whether it could have been allowed in principle, but whether there are good reasons to think it actually occurred. The sources are silent on such a move, and the overall context does not make it likely.
+ The Jewish or Roman authorities might have removed Jesus’ body from Joseph’s tomb to prevent it from becoming a shrine and simply not informed His followers.
1. Such an action would likely have created records or at least strong, consistent counter-traditions. If the authorities had taken the unusual step of relocating a high-profile crucifixion victim’s body, there would have been an obvious interest in appealing to this fact once the resurrection was publicly preached. Yet we do not find a trace of a clear, alternative burial story from official sources in the early record. 2. The simplest way to suppress the resurrection claim would have been to produce the body. When the disciples proclaimed that God raised Jesus and that His tomb was empty, authorities could have countered by publicizing the new burial location or producing the remains, especially if they themselves had ordered the transfer. The absence of such a response argues against the idea that they had control of a relocated corpse. 3. The earliest Jewish explanation assumes the body is missing, not safely relocated. According to the Gospel of Matthew, the Jewish response was to claim that the disciples stole the body. While this source is Christian, the polemic it records presupposes that Jesus’ body was not available to be displayed. A simple, official relocation would have provided a more powerful counter than alleging theft.
+ The followers of Jesus might have gone to the wrong tomb, found it empty, and mistakenly believed it was His.
1. The burial accounts suggest clear, specific knowledge of the tomb’s location. The Gospels describe some of Jesus’ followers, including women who had witnessed the burial, later returning to the same tomb. Joseph of Arimathea’s involvement and the reference to a particular new tomb cut in rock indicate that this was an identifiable place, not a vague or anonymous grave among many. 2. The “wrong tomb” idea does not fit the ongoing controversy in Jerusalem. If the early Christians were simply mistaken about the tomb, the authorities or local residents could have indicated the correct location and shown that Jesus’ body was still there. Instead, the polemic assumes an empty tomb problem, not a “you have the wrong address” misunderstanding. 3. Misidentification does not explain the structured appearance traditions and conversions of skeptics. Even if a wrong-tomb error occurred, it would not by itself generate the multiple, coordinated reports of post-mortem appearances to named individuals and groups, including former opponents like Paul. The hypothesis thus fails to account for major parts of the data and functions more as a partial excuse than a full explanation.
+ Although the displaced body theory is speculative, it keeps the explanation natural. A speculative natural explanation is still better than invoking a miracle.
1. Historical explanations are evaluated by fit with the evidence, not by “naturalness” alone. While historians typically look for natural causes, an explanation that is weakly supported, highly conjectural, and leaves major facts unexplained is not automatically superior just because it avoids the supernatural. Explanatory power, coherence, and plausibility all matter. 2. The displaced body theory is both ad hoc and incomplete. It relies on an unrecorded body transfer for which we have no direct evidence, clashes with burial customs, and fails to address the appearance traditions and radical transformation of the disciples. As such, it does not offer a comprehensive account of the resurrection data. 3. If independent reasons make belief in God reasonable, a miraculous explanation can be the best overall account. If arguments from cosmology, morality, fine-tuning, and so on render theism plausible, then God’s raising Jesus from the dead is not an arbitrary add-on but a theologically meaningful act. In that context, a resurrection may provide a simpler and more unifying explanation of the empty tomb and appearances than a highly speculative natural scenario like the displaced body hypothesis.

Contra Hallucination Hypothesis

(P1) The resurrection appearances exhibit a pattern (multiple, varied, group, and to skeptics) that does not fit what is known about hallucinations or private visions. The earliest sources report that Jesus appeared on multiple occasions, in different locations, to a range of people: individual disciples, small groups, and “more than five hundred” at one time. Some of these were former skeptics or opponents (James, the brother of Jesus, and Paul). Hallucinations and similar visionary experiences are typically private, individual, and idiosyncratic; there is no established psychological parallel to large, coordinated, multi-person experiences of the same figure across diverse contexts.

(P2) Hallucinations or visions by themselves would not naturally lead first-century Jews to proclaim a bodily resurrection with an empty tomb. In the ancient Jewish worldview, visions of the deceased were generally taken as evidence that the person was dead and in the afterlife, not as proof that the person had been bodily raised. At most, private experiences of Jesus after His death could have been interpreted as confirming His vindication in heaven. They would not by themselves explain the strong claim that His grave was empty and that God had already raised Him bodily from the dead within history.

(P3) The hallucination hypothesis fails to explain the empty tomb and the early, unified proclamation of physical resurrection in the very city of Jesus’ execution. Even if one granted that some disciples had subjective experiences of Jesus, this would not remove His body from the grave. The empty tomb tradition is early, multiple, and implied even by Jewish polemic that accuses the disciples of theft. Moreover, the earliest Christian preaching in Jerusalem centrally proclaims that God raised Jesus and that His tomb was empty. A theory limited to hallucinations or visions leaves this physical side of the evidence unexplained or treats it as a later, ad hoc addition.

(P4) Because of these problems, many scholars (including critical ones) acknowledge that simple hallucination theories cannot by themselves account for the core resurrection data. Even some non-Christian or skeptical New Testament scholars admit that the disciples and others had powerful experiences they took to be encounters with the risen Christ, and that the hallucination hypothesis faces serious difficulties in explaining the full pattern. The combination of group appearances, transformation of former skeptics, the role of the empty tomb, and the early, concrete resurrection proclamation makes a pure hallucination theory inadequate for explaining the historical origins of the Easter faith.

(C) Therefore, the hallucination hypothesis is not a satisfactory explanation of the resurrection appearances, the empty tomb, or the disciples’ robust belief that Jesus had been bodily raised from the dead.

+ The disciples loved Jesus and were emotionally devastated by His death. Intense grief and religious expectation can lead to hallucinations or visionary experiences.
1. The disciples were not expecting an individual resurrection of this kind. First-century Jews anticipated a general resurrection at the end of the age, not the isolated resurrection of the Messiah in the middle of history, especially after a shameful crucifixion. Far from expecting Jesus to rise, they are depicted as confused and unbelieving when confronted with early reports of the empty tomb and appearances. 2. Emotional grief does not explain group experiences and appearances to skeptics. Grief-related hallucinations are typically private and limited to those who loved the deceased. Yet the early tradition includes group appearances and appearances to individuals like James and Paul, who were not in a state of bereaved devotion to Jesus at the time. This pattern goes beyond what grief alone would predict. 3. Intense feelings do not by themselves remove a body from a tomb or create a durable, public proclamation. Even if some disciples had visionary experiences under emotional strain, that would not empty the tomb or explain why, very soon afterward, they confidently preached the bodily resurrection of Jesus in Jerusalem, appealing to public facts rather than purely private experiences.
+ Psychological phenomena like group hysteria or suggestion can lead multiple people to report similar visionary experiences. The group appearances could be explained this way.
1. Clinical hallucinations remain essentially individual events. In psychological case studies, hallucinations are inner experiences in one person’s mind. “Shared” experiences of this sort usually reduce to individuals influencing each other’s interpretations, not literally seeing the same external figure in a coordinated way. There is no well-documented case of hundreds of people hallucinating the same detailed, physical figure at the same time and place. 2. The resurrection appearances are diverse in time, place, audience, and mood. The sources present appearances in different locations (Jerusalem, Galilee, the road to Damascus), to different groups and individuals, and in a range of emotional situations (fear, doubt, disbelief, persecution). This variety makes it difficult to cast the whole pattern as one instance of group hysteria or a single contagious event. 3. The hypothesis of mass, coordinated hallucinations lacks independent support. To invoke rare, large-scale group hallucinations across multiple contexts without strong analogies in the psychological literature is highly speculative. A theory that multiplies unprecedented phenomena in order to avoid a resurrection is not clearly simpler or better supported than the claim that the disciples experienced something objectively real.
+ People in many cultures report seeing or sensing deceased loved ones. The resurrection appearances could just be ordinary grief-visions interpreted through a religious lens.
1. Ordinary “visions of the dead” are usually taken as signs that the person is still dead. Across cultures, when someone reports seeing a deceased friend or relative, this is commonly understood as evidence that the person has passed on to another realm, not that the person is bodily alive again. Ancient Jews would not have taken a mere vision of Jesus as proof of a physical resurrection. 2. The early Christian claim goes far beyond typical after-death experiences. The disciples preached that Jesus’ tomb was empty, that He had been raised bodily, and that He was the firstfruits of the eschatological resurrection. This is a precise, bold theological claim, not just a generic sense that “His spirit lives on.” Simple grief-visions do not naturally generate this kind of robust resurrection theology. 3. Explaining away the appearances as generic visions still leaves multiple other facts untouched. Even if some experiences were visionary, the hypothesis does not explain the empty tomb, the early and structured resurrection creed in 1 Corinthians 15, or the conversions of figures like James and Paul under hostile or skeptical starting conditions. Reducing all the appearances to ordinary “visions of the deceased” underestimates the scope and specificity of the historical data.
+ If the empty tomb narrative developed later, then hallucinations or visions alone might be enough to explain the earliest resurrection belief.
1. There are strong reasons to regard the empty tomb as an early tradition. The empty tomb account is embedded in multiple, independent strands of tradition and presupposed by early preaching in Jerusalem. The Jewish accusation that the disciples stole the body assumes that the tomb was known to be empty. These factors point to the emptiness of the tomb being part of the historical core, not a late legend tacked on. 2. Early resurrection proclamation already reflects a bodily and historical emphasis. From the beginning, Christian preaching centers on what God did in history to Jesus’ body, not merely on inward experiences. Paul’s language in 1 Corinthians 15, for example, stresses that Jesus “was buried” and “was raised” and that the risen Christ appeared to many witnesses, implying continuity between the buried body and the raised one. 3. A theory that removes a major piece of evidence to save a hypothesis is methodologically suspect. To preserve the hallucination theory, this defeater must downplay or discard the empty tomb data rather than integrate it. A more balanced historical approach considers all the main lines of evidence together and asks what best explains them as a whole, not what hypothesis can be made to work if important data are set aside.
+ Perhaps no single hallucination theory fits perfectly, but a mix of visions, misremembered events, and gradual story development is still more reasonable than a supernatural resurrection.
1. Multiplying speculative elements does not necessarily increase explanatory power. A hybrid theory that combines hallucinations, memory distortions, and legendary embellishment may sound flexible, but it quickly becomes complex and difficult to test. By contrast, the claim that Jesus truly rose and appeared to many provides a single, coherent explanation for the empty tomb, the variety of appearances, and the rapid, unified resurrection proclamation. 2. The time frame and structure of early tradition limit room for slow legendary growth. The creed in 1 Corinthians 15 and other early texts show that, within a few years, the church already had a definite list of resurrection appearances and a strong bodily-resurrection message. This compresses the window for a gradual, uncontrolled evolution of stories into something approaching what we actually see. 3. If God exists, a resurrection can be a more reasonable explanation than an elaborate, low-probability natural mosaic. If one already has good reason to believe in God’s existence, then a miraculous act at a pivotal moment in salvation history is not arbitrary. In that context, positing that God raised Jesus may be more rational than postulating a complex set of rare psychological and sociological events that happen to mimic all the marks of a real resurrection without one actually occurring.

Contra Legend Hypothesis

(P1) The legend hypothesis claims that resurrection stories gradually developed over time as pious fiction rather than stemming from early eyewitness testimony. According to this view, the earliest followers of Jesus may have had some kind of vague conviction that He was vindicated by God, but detailed accounts of an empty tomb and bodily appearances to many people arose much later as stories were retold and embellished. On this account, the resurrection narratives represent a long process of legendary development rather than reliable early memory of what actually happened.

(P2) Key resurrection traditions (especially the 1 Corinthians 15 creed) are extremely early and rooted in the eyewitness generation, leaving little time for a purely legendary process to create the core claims. Most scholars date the creed Paul quotes in 1 Corinthians 15:3–7 to within a few years of Jesus’ death, drawing on testimony from figures like Peter, James, and the Jerusalem apostles. This early formula already includes the claims that Christ died, was buried, was raised, and appeared to named individuals and groups, including more than five hundred people at once. Such a structured, resurrection-centered tradition so close to the events is difficult to explain if the core resurrection belief were a much later legendary invention.

(P3) The character of the Gospel resurrection narratives shows restraint and proximity to eyewitnesses, not the extravagance typical of late legends and apocryphal stories. Compared to later apocryphal gospels, the canonical resurrection accounts are relatively sober. They lack the outlandish, highly embellished details found in some second-century writings (such as talking crosses or wildly fantastical scenes). The Gospels also preserve numerous “embarrassing” features, like women as the first witnesses, the disciples’ fear and doubt, and the initial unbelief of some followers...features that legendary story-tellers aiming to glorify their heroes would be unlikely to invent. These marks support the claim that the narratives are anchored in genuine early memory rather than free-floating legend.

(P4) The legend hypothesis cannot easily account for the rapid, widespread, and unified proclamation of bodily resurrection in the very first Christian communities. From the earliest documents we possess (such as Paul’s letters), Christians across different cities are already proclaiming the bodily resurrection of Jesus as the central message of the faith. Paul assumes that his audiences have already been taught this and treats it as non-negotiable. This rapid, geographically broad agreement is implausible if the resurrection stories were slowly evolving legends that only emerged after a long period of theological reflection and story growth removed from the eyewitness generation.

(P5) Because the legend hypothesis fits poorly with the early dating and nature of the sources, many scholars...even critical ones...accept the core facts (empty tomb, appearances, early belief) while rejecting a purely legendary origin. A number of non-Christian or skeptical scholars are willing to grant, as historical facts, that the tomb was found empty (by someone), that various individuals and groups had experiences they interpreted as appearances of the risen Jesus, and that the earliest disciples came quickly to believe in His resurrection. They may explain these facts differently, but they generally do not dismiss them as mere legend. This broad acknowledgment reflects the inadequacy of a simple “it’s all legend” approach to the historical data.

(C) Therefore, the legend hypothesis is not an adequate explanation of the origin and content of the early Christian resurrection proclamation.

+ In some cultures, legends and miracle stories can arise very quickly. The resurrection narratives might be early and still largely legendary.
1. Rapid legendary growth is possible, but it still requires space between the events and firm, stable tradition. For a legend to take hold, there typically needs to be a period of retelling in which eyewitness checks fade, details become flexible, and communities accept embellishments without effective correction. In the case of Jesus’ resurrection, however, the key claims are already fixed in creeds and preaching within a few years, while many witnesses are still alive and active. 2. The central resurrection claim is not a minor embellishment but the heart of the earliest message. Delivering Jesus from death and exalting Him as risen Lord is not an optional flourish added to an otherwise complete religion; it is the foundation of Christian preaching from the very beginning. This central role is difficult to reconcile with the idea that it emerged only as an early legend, rather than as the core conviction of the first believers. 3. The early presence of named witnesses suggests ongoing accountability, not free legendary invention. Traditions like 1 Corinthians 15 explicitly name Peter, James, the Twelve, and the five hundred, many of whom Paul implies are still alive. Inviting appeal to living witnesses is inconsistent with an unconstrained legendary process in which no one can check or correct what is being claimed.
+ The written Gospels come from decades after the events. That is plenty of time for resurrection legends to form and be written down as if they were history.
1. Decades are not necessarily enough for core, publicly contested facts to become pure legend. The Gospels were written roughly 30–60 years after Jesus’ death, within living memory. In that time frame, eyewitnesses and their close associates were still around to confirm or dispute major claims, especially about a public execution and subsequent appearances. 2. The Gospel writers are drawing on earlier, already fixed traditions. Luke explicitly states that he is compiling accounts from earlier witnesses and written sources. The resurrection narratives he records are thus not being invented for the first time around AD 70–90; they reflect longstanding beliefs and stories that predate the written texts, anchored in the earliest church. 3. The canonical Gospels compare favorably to known examples of later legendary writings. When we contrast them with clearly legendary apocryphal gospels from the second century, we see a marked difference in tone and style. The canonical texts are more restrained and historically situated, which is what we would expect if they rest on genuine early testimony rather than on fully developed legend cycles.
+ Differences among the Gospel accounts (number of women, angels, specific details) indicate that the stories became legendary as they were retold.
1. Minor variations are what we expect from multiple witnesses to real events. When independent accounts describe the same event, especially in ancient historiography, they often differ in secondary details (such as order of mention, number of people highlighted, or circumstantial specifics) while agreeing on the main points. This pattern is consistent with independent testimony, not necessarily with fabrication. 2. The core facts remain consistent across the Gospels. All four canonical Gospels affirm that Jesus was crucified, buried, that the tomb was discovered empty on the first day of the week by followers (including women), and that Jesus appeared alive afterward. The alleged discrepancies concern peripheral matters, not the central resurrection claim. 3. Full legendary fabrication often produces harmonized, not divergent, accounts. Where stories are consciously crafted as fiction or theological allegory, authors can and do smooth over difficult details. The presence of unresolved tensions and minor differences may actually signal that the evangelists were preserving traditions they received, rather than inventing or harmonizing them to create a seamless legend.
+ Ancient religions featured myths of dying and rising gods. The resurrection stories about Jesus could be one more version of this widespread legendary pattern.
1. The supposed parallels are often superficial or based on questionable reconstructions. Many “dying and rising god” figures differ significantly from Jesus: their stories are cyclical nature myths, symbolic dramas, or non-historical mythologies tied to fertility and seasons, not claims about a specific historical individual executed under a known Roman governor and raised within a particular cultural context. 2. First-century Jews were resistant to pagan mythological categories. The early Christian movement emerged from a strict monotheistic Jewish environment that rejected pagan gods and myths. It is historically implausible that these Jews would straightforwardly adopt a pagan “dying and rising god” pattern and overlay it on their Messiah, especially when they were highly sensitive to idolatry and doctrinal purity. 3. The earliest sources insist on a concrete, historical resurrection in space and time. The New Testament writers locate Jesus’ death and resurrection in specific places, under specific rulers, and tie them to Israel’s Scriptures and history. This historical framing is a poor fit with generic myth cycles and speaks instead to claims about real events God has brought about in the world.
+ Perhaps there were some initial visionary or spiritual experiences, and then legendary development filled in the rest. That combination might be more plausible than a literal resurrection.
1. A mixed theory must still explain the early, strong, bodily-resurrection language. Even if some experiences were visionary, the earliest Christian proclamation insists that Jesus was raised from the dead in a way that involved His body, not merely His ongoing spiritual presence. This physical emphasis appears too early and too centrally to be a late legendary overlay. 2. Combining partial visions, partial legend, and partial misremembering quickly becomes complex and speculative. A hybrid theory often attempts to account for each piece of data with a different ad hoc explanation...some hallucinations here, some legend there, some confusion elsewhere. This mosaic lacks the simplicity and coherence of the hypothesis that Jesus truly rose and appeared to many, which straightforwardly unites the empty tomb and appearances. 3. If God’s existence is already reasonably supported, the resurrection is not less rational than a layered, low-probability natural story. Given independent arguments for theism, a divine act at the heart of salvation history fits naturally within a theistic worldview. In this light, the claim that God raised Jesus from the dead can be more reasonable than a complicated scenario in which partial experiences and rapid legend-formation combine to mimic all the features of a genuine resurrection without one having actually taken place.

Evidence for the Reliability of the NT Bible

Early Dating and Eyewitness Proximity of the New Testament

(P1) Historical documents written within living memory of the events they describe, and drawing on eyewitness testimony, are generally more reliable than late, anonymous legends. In ordinary historical practice, sources that are: (1) Close in time to the events, (2) Connected to identifiable eyewitnesses or close associates, and (3) Embedded in a community that cares about those events, are given greater weight than sources that arise much later, far from the original setting, and with no clear link to witnesses. The shorter the gap between event and record, the less opportunity there is for wholesale legend to displace core historical memory, especially when other knowledgeable parties are still alive to correct falsehoods. See also: • CE / NT Criticism: Convergence of Independent New Testament Traditions • CE / NT Criticism: Internal Marks of Eyewitness Testimony and Verisimilitude

(P2) Key New Testament writings (especially Paul’s letters, the Gospels, and Acts) are best dated to within a few decades of Jesus’ death, squarely within the lifetime of eyewitnesses and contemporaries. Multiple lines of mainstream scholarship...across a wide spectrum of views...support relatively early dates for major New Testament documents: (1) Paul’s undisputed letters (c. AD 48–60). 1 Corinthians, Galatians, 1 Thessalonians, Romans, and others are widely dated to the 50s AD, roughly 20–30 years after Jesus’ crucifixion (c. AD 30). In 1 Corinthians 15:3–7, Paul quotes a pre-existing creed about Jesus’ death, burial, resurrection, and appearances that most scholars date to within a few years of the events it describes. (2) Acts likely before the mid-60s AD. Acts ends with Paul alive and under house arrest in Rome, with no mention of his trial or death (c. mid-60s), the deaths of Peter and James, or the destruction of the Jerusalem Temple in AD 70. The most natural explanation is that Acts was written before these major events, placing it in the early-to-mid 60s. (3) Luke before Acts, Mark and Matthew earlier still. Since Acts is the sequel to Luke (Acts 1:1–2), Luke must be earlier than Acts. Many scholars date Luke to the 60s, with Mark and Matthew in the 50s–60s. This puts at least one and probably multiple Gospels within 30–40 years of the crucifixion, when many eyewitnesses and contemporaries were still alive. (4) John within living memory as well. Even relatively later datings for John (e.g., 80s–90s AD) still place it within the lifetime of at least some eyewitnesses and second-generation disciples. And there are good reasons, argued by some scholars, for considering an earlier date for John as well. These timeframes are well within what historians normally consider compatible with serious, historically grounded biography...especially in an oral culture that valued memorization and communal transmission.

(P3) The New Testament writings explicitly and implicitly claim close contact with eyewitnesses and early participants in the events they narrate. (1) Luke’s explicit method statement. Luke begins by noting that he has followed all things “closely for some time past” and that his account is based on “those who from the beginning were eyewitnesses and ministers of the word” (Luke 1:1–4). This is exactly the kind of historian’s preface we find in other ancient historical works. (2) John’s claim to eyewitness testimony. The Fourth Gospel grounds its narrative in the testimony of the “disciple whom Jesus loved” (John 21:24), indicating that the author is either this eyewitness or closely dependent on him: “This is the disciple who is bearing witness about these things, and who has written these things, and we know that his testimony is true.” (3) Acts’ “we” sections and proximity to Paul. Acts shifts into first-person plural (“we”) in several travel narratives (e.g., Acts 16:10–17; 20:5–15; 21:1–18; 27:1–28:16), strongly suggesting that the author was a traveling companion of Paul for parts of his ministry. This gives Acts direct access to an apostolic eyewitness and his circle. (4) Paul’s personal acquaintance with other eyewitnesses. In Galatians 1–2 and 1 Corinthians 15, Paul notes that he met Peter (Cephas), James, and other apostles, and that he received and passed on tradition that was already established in the Jerusalem church. He emphasizes that he is not preaching a message invented in isolation, but one consistent with those “who were apostles before me” (Galatians 1:17). (5) Early external testimony (e.g., Papias, Irenaeus). Early Christian writers like Papias and Irenaeus report that Mark wrote down Peter’s preaching and that Matthew compiled sayings or a Gospel in the “Hebrew dialect.” While details are debated, this tradition supports a close connection between the canonical Gospels and the apostolic eyewitness circle. Taken together, these internal and external indications present the New Testament authors not as distant, anonymous compilers, but as individuals personally connected to eyewitnesses or being eyewitnesses themselves. See also: • CE / NT Criticism: Literary/Historical Character of the Gospels • CE / NT Criticism: Convergence of Independent New Testament Traditions

(P4) Late, anonymous, and legendary gospels stand in sharp contrast to the canonical Gospels, both in date and in historical character, and therefore do not undermine the early and eyewitness-based nature of the New Testament accounts. (1) Apocryphal gospels generally arise in the 2nd century or later. Documents such as the Gospel of Thomas, Gospel of Peter, Gospel of Judas, and others typically date to well after the first century...often 100–200 years after Jesus. They emerge from later theological movements (e.g., Gnosticism) rather than from the original Palestinian context. (2) Their style and content are markedly different. These later writings tend to lack the dense geographical, political, and cultural specificity found in the canonical Gospels. They often present Jesus delivering abstract, esoteric sayings or performing fantastical, unhistorical miracles, with little concern for realistic narrative setting. (3) Early Christians did not “suppress” equal competitors. The earliest church fathers, when they discuss the four canonical Gospels, treat them as long-established and widely used. The later apocryphal writings are often explicitly rejected or ignored. The pattern is not of powerful bishops excluding rival early accounts, but of the church recognizing, and continuing to use, the earliest texts connected to apostles and their close associates. Thus, appeals to “other gospels” do not weaken the case for early, eyewitness-connected canonical Gospels; they actually highlight how different the canonical four are from the genuinely late and legendary material. See also: • CE / NT Criticism: Canonical Gospels vs. Apocryphal Gospels • CE / NT Criticism: Undesigned Coincidences as Evidence of Gospel Reliability

(P5) Given their early dates and close connection to eyewitnesses, the New Testament documents deserve a presumption of historical reliability, especially regarding central events like Jesus’ ministry, crucifixion, burial, and post-mortem appearances. When the major New Testament writings are: (1) Written within living memory of the events, (2) Produced by or in close contact with eyewitnesses, (3) Internally coherent and realistic, and (4) Supported by undesigned coincidences and external corroboration, the burden of proof shifts. Skeptics cannot simply dismiss them as “late legends” or “anonymous myths.” Instead, they must offer careful, evidence-based reasons to override the strong initial presumption that such sources are at least broadly reliable historical witnesses. This presumption does not require believing that every minor detail is beyond question. It does, however, justify trusting their main lines of testimony...particularly about Jesus’ public ministry, His crucifixion under Pontius Pilate, and the experiences that His earliest followers interpreted as encounters with the risen Christ. See also: • CE / Resurrection: Minimal Facts Argument • CE / Resurrection: Maximal Facts Argument

(C) Therefore, the early dating and eyewitness proximity of the New Testament writings strongly support their general historical reliability and undercut skeptical claims that they are late, legendary, or detached from the real Jesus of history.

+ Isn’t early dating just an apologetic move? Critical scholars usually date the Gospels late, so your early dates are biased and unreliable.
1. Even many critical scholars place the Gospels within 40–60 years of the events. A common critical dating scheme (Mark ~70, Matthew and Luke ~80s, John ~90s) still puts all four Gospels within roughly a generation or two of Jesus’ life...far earlier than the “centuries-later legend” caricature. That is already close enough for serious historical work, especially in an oral culture. 2. There are strong positive arguments for somewhat earlier dates. The abrupt ending of Acts, the portrayal of the Temple as still standing in the Synoptics, the lack of clear awareness of post-70 church controversies in some texts, and other considerations give good reason to consider dates in the 50s–60s for Mark, Matthew, Luke-Acts, and not too long after for John. These are not arbitrary apologetic assertions but arguments that can be evaluated on historical grounds. 3. “Critical consensus” is not static or unanimous. Scholarly opinion has shifted over time and is often divided. There are well-qualified scholars (not just conservative apologists) who defend earlier datings and strong connections to eyewitness testimony. The key question is not how many hold a view, but what the evidence supports. See also: • CE / NT Criticism: External Corroboration – Archaeology and Non-Christian Sources • CE / NT Criticism: Convergence of Independent New Testament Traditions
+ Even if the texts are from the first century, oral tradition can change stories rapidly. So early dating doesn’t guarantee historical reliability.
1. Early Christian communities were not casual about the content they preached. The New Testament portrays the apostles and early teachers as deliberately “delivering” and “receiving” specific traditions (1 Corinthians 11:23; 15:3). Repetition in liturgy, catechesis, and preaching would naturally stabilize key narratives and sayings. 2. The presence of living eyewitnesses restrains wild distortion. When people who were actually present at the events are still alive and active in the community, there is a natural check on extreme alterations. This is especially true for public events like Jesus’ crucifixion and the early proclamation of His resurrection. 3. The pattern of undesigned coincidences suggests preservation, not radical reshaping. The many interlocking details across Gospels, Acts, and Paul’s letters indicate a consistent core being transmitted, not stories being freely invented and re-invented. Oral transmission can preserve information with remarkable fidelity, particularly when the community values that information and has mechanisms for guarding it. See also: • CE / NT Criticism: Undesigned Coincidences as Evidence of Gospel Reliability • CE / NT Criticism: Internal Marks of Eyewitness Testimony and Verisimilitude
+ Since the Gospels are technically anonymous in the text and modern scholars dispute traditional authorship, we cannot treat them as eyewitness-related documents.
1. Ancient biography often omitted explicit author names within the text. It was common in antiquity for titles and author attributions to be carried by the book’s opening page, cover, or accompanying tradition rather than by a signature in the main text. The absence of “by Matthew” inside the Gospel does not mean the early church had no idea who wrote it. 2. The uniform early tradition about Gospel authorship is significant. From the second century onward, sources like Papias, Irenaeus, and the Muratorian Fragment consistently attribute the Gospels to Matthew, Mark, Luke, and John, with no competing names offered. This stability is unusual if these attributions were late inventions, especially for figures like Mark and Luke who were not apostles and would not be obvious “marketing choices.” 3. Eyewitness proximity does not require direct authorship by an apostle. Even if one adopts more cautious views about authorship, the evidence still points to the Gospels being written within communities closely linked to the apostolic eyewitnesses, drawing on their testimony. That is enough for strong historical value, just as modern historians rely on documents produced by associates of key figures. See also: • CE / NT Criticism: Canonical Gospels vs. Apocryphal Gospels • CE / NT Criticism: Literary/Historical Character of the Gospels
+ Being early and close to the events doesn’t guarantee truth. Other religions have early texts too, but we don’t automatically trust all of their miracle stories.
1. Early dating is one component in a cumulative case, not the whole argument. Christians do not claim that “early = true” by itself. Rather, early dating combined with eyewitness proximity, internal realism, undesigned coincidences, and external corroboration together create a strong case for reliability. 2. The New Testament’s evidential pattern is unusually rich. Compared to many other religious texts, the New Testament offers multiple independent sources, specific historical and geographical anchors, cross-checked incidental details, and strong integration with external history (Roman officials, Jewish leadership, major events like the Temple’s destruction). 3. The same historical standards apply across traditions. If other ancient religious texts meet similar criteria (early, multiple, independent, realistic, corroborated), that counts as evidence for the historical claims they make as well. Historical method is not selectively altered for Christianity. The point is that, by those fair standards, the New Testament does very well. See also: • CE / NT Criticism: External Corroboration – Archaeology and Non-Christian Sources • CE / NT Criticism: Undesigned Coincidences as Evidence of Gospel Reliability
+ Legends don’t need centuries to form. They could have developed in the first few decades, so early dating doesn’t rule out heavy legendary embellishment of Jesus’ story.
1. Rapid legendary growth on a massive scale is historically implausible in a hostile environment. The early Christian message was proclaimed publicly in the very city where Jesus was crucified, in the presence of opponents who had every motive to refute false claims. The notion that a wholly unhistorical picture of Jesus’ miracles and resurrection could take over in a few short decades, without pushback from those who knew otherwise, stretches credulity. 2. The New Testament shows continuity between earliest creedal material and later narrative detail. The resurrection creed in 1 Corinthians 15, which most scholars date to within a few years of the crucifixion, already includes death, burial, resurrection “on the third day,” and appearances to named individuals and groups. The Gospels flesh out these same core claims, rather than presenting a radically different story that would suggest uncontrolled legendary explosion. 3. The internal texture of the Gospels looks like remembered history, not wild legend. The realistic dialogue, naming of minor characters, specific times and places, embarrassment of the disciples, and the presence of undesigned coincidences all point to controlled transmission of real events rather than free, mythic invention.

Undesigned Coincidences as Evidence of Gospel Reliability

(P1) Undesigned coincidences are subtle, interlocking details between independent accounts that fit together in a natural way, best explained if the authors are reporting real events. An “undesigned coincidence” occurs when one document mentions a detail that raises a natural question, and another document...without apparent design to answer it...provides just the right incidental information that makes sense of the first. The fit is too casual and unforced to look like copying or collusion. Such patterns are exactly what we expect if multiple witnesses (or those drawing on witnesses) are independently describing the same real events from different angles. Examples include: (1) One Gospel mentioning an event or saying without explanation, while another quietly supplies the background that makes it intelligible. (2) Acts explaining personal details about a character that clarify brief remarks in Paul’s letters, and vice versa. See also: • CE / NT Criticism: Internal Marks of Eyewitness Testimony and Verisimilitude • CE / NT Criticism: Convergence of Independent New Testament Traditions

(P2) The Gospels and Acts contain numerous and varied undesigned coincidences, both among themselves and with Paul’s letters, which strongly indicate independent access to a shared historical reality. Across the New Testament, we find many instances where one book casually illuminates another: (1) John mentions Jesus asking Philip where to buy bread (John 6:5), but gives no reason. Luke earlier notes that Philip is from Bethsaida (John 1:44), the very region where the feeding of the five thousand takes place (Luke 9:10), explaining why Jesus would ask Philip in particular. (2) Mark notes that many were “coming and going” so that the disciples had no leisure even to eat (Mark 6:31), but does not say why Galilee would be unusually crowded. John explains that “the Passover, the feast of the Jews, was at hand” (John 6:4), naturally accounting for the influx of people. (3) Acts mentions that the proconsul Sergius Paulus believed after Paul’s miracle on Cyprus (Acts 13:7–12). Inscriptions and other evidence independently confirm the historical existence of a Lucius Sergius Paulus as a Roman official, matching the sort of incidental realism we find in undesigned coincidences. (4) Multiple examples link the Gospels with Acts and with Paul’s letters: personal names, travel plans, local customs, and offhand remarks in one text that are neatly clarified in another, without any sign of deliberate harmonization. These patterns are cumulative and cross-cut different authors (e.g., John with the Synoptics, Acts with Paul), reinforcing the conclusion that we are dealing with overlapping, historically grounded testimony, not a single late literary construction. See also: • CE / NT Criticism: External Corroboration – Archaeology and Non-Christian Sources • CE / NT Criticism: Early Dating and Eyewitness Proximity of the New Testament

(P3) Fiction, collusion, or late legendary development are unlikely to produce this pattern of casual, cross-document fit, especially when the details often appear minor or even theologically irrelevant. If the Gospel writers and other New Testament authors were inventing stories or freely reshaping traditions, we would expect: (1) Either obvious literary artistry that draws attention to the connections, or (2) Contrived harmonization where one author clearly borrows another’s distinctive details in a heavy-handed way. Instead, many coincidences are: (1) Quiet and easily overlooked, suggesting the authors were not trying to engineer them. (2) Involving incidental details (geography, names, offhand motives) that serve no clear theological agenda but fit like pieces of a puzzle when texts are compared. (3) Spread across works traditionally linked to different lines of transmission (e.g., Johannine vs. Synoptic; Pauline letters vs. Acts), making coordinated fabrication increasingly implausible. A forger or late legendary redactor would have little reason to plant dozens of subtle, easily-missed interlocks that only emerge when texts are read side by side with historical attention. See also: • CE / NT Criticism: Canonical Gospels vs. Apocryphal Gospels • CE / NT Criticism: Literary/Historical Character of the Gospels

(P4) Therefore, the presence of many undesigned coincidences across the New Testament provides strong, positive evidence that the Gospel and Acts narratives are rooted in truthful, historically reliable testimony rather than in late legend or theological fiction. Undesigned coincidences function like independent lines of cross-examination in a courtroom: separate witnesses, with different emphases and memories, nonetheless “fit” together in ways best explained if they are each in contact with the same set of real events. This pattern: (1) Undermines skeptical claims that the Gospels are late, derivative, and largely legendary. (2) Supports treating the New Testament as broadly trustworthy when it reports events, settings, and persons. (3) Lends particular credibility to the central claims...such as the crucifixion, burial, empty tomb, and post-resurrection appearances...for which we see similar interlocking patterns. Thus, undesigned coincidences undergird a maximal-data approach to the resurrection by strengthening the case that the New Testament writers are sober, informed witnesses rather than theological novelists. See also: • CE / Resurrection: Maximal Facts Argument • CE / Resurrection: Three Facts Argument

(C) Therefore, undesigned coincidences across the New Testament are best explained if the Gospels and Acts are generally reliable historical documents grounded in real events and genuine eyewitness (or close-up) testimony.

+ Apologists are simply seeing patterns where none exist. The supposed ‘undesigned coincidences’ are cherry-picked and based on reading too much into small details.
1. Many coincidences involve precise, content-rich interlocks, not vague similarities. In a typical undesigned coincidence, one text contains an unexplained or slightly puzzling feature, and another text...often in a different genre or by a different author...gives a specific detail that neatly answers the puzzle. These are not mere thematic parallels but tightly keyed fits (for example, explaining why a particular person is addressed, why a location is crowded, or why a particular term is used). 2. The pattern is cumulative across dozens of examples. Any single coincidence might be dismissed as chance. But when we have many such interlocking cases across multiple documents (Gospels and Acts with Paul’s letters), the probability of random pattern-spotting becomes small. A cumulative, structured pattern is more naturally explained by a shared historical reality. 3. The explanatory power of the coincidences is testable and concrete. Skeptics can examine specific proposed examples and ask: Does the second text really provide a natural explanation for the first? Are there clear cases where one text fills in a specific gap in another? This is not a purely subjective impression but something that can be critically evaluated case by case. See also: • CE / NT Criticism: Convergence of Independent New Testament Traditions
+ The Gospel writers were using each other’s material or drawing on common traditions. Apparent coincidences just reflect dependence, not independence or historicity.
1. Many coincidences occur precisely where dependence theories predict sameness, not complementary detail. If one Evangelist were simply copying another in a straightforward way, we would expect close verbal overlap, not subtle filling-in of unexplained details. Instead, we often find one Gospel mentioning a fact without comment and another independently including a different detail that incidentally explains the first, in a way not easily reducible to simple copying. 2. Some of the strongest cases link different literary strata (e.g., Paul and Acts, John and the Synoptics). Undesigned coincidences do not only occur among the Synoptics. They also appear between Acts and Paul’s letters, and between John and the Synoptics...texts with different styles, purposes, and probable sources. This cross-genre, cross-author interlocking is harder to explain by a single line of literary dependence. 3. Shared tradition itself is more likely to preserve real events than pure legend. Even if some dependence or shared oral tradition is granted, undesigned coincidences still show that these traditions preserve consistent, interlocking factual content. That is evidence for the reliability of the underlying historical core, not against it. See also: • CE / NT Criticism: Early Dating and Eyewitness Proximity of the New Testament
+ Skilled authors may have intentionally woven these interlocking details into their narratives to give an impression of realism, even if the stories are not historically true.
1. The coincidences are typically obscure and not highlighted for the reader. If the authors wanted to impress readers with clever interconnections, they would likely draw attention to them or structure them more obviously. Instead, many undesigned coincidences are only noticed when comparing texts carefully, often across centuries of scholarship. This subtlety points away from deliberate literary artistry aimed at persuasion. 2. The details involved are often theologically neutral or even awkward. Some coincidences revolve around geographically or biographical minutiae that do little to support a doctrinal point: hometowns, travel routes, side comments about crowds or minor characters. Investing effort to fabricate such details purely to create hidden connections is implausible, especially when many early readers would never detect them. 3. Coordinated fabrication across multiple authors and decades would require an implausible level of planning. To engineer a network of interlocking details across different books, with different authors, styles, and audiences, would demand extraordinary coordination and foresight. The more modest and historically grounded explanation is that the authors are drawing on overlapping knowledge of real events. See also: • CE / NT Criticism: Literary/Historical Character of the Gospels
+ At best, undesigned coincidences show that some non-miraculous details are accurate. That does not mean we should trust the miraculous claims like the resurrection.
1. Establishing general reliability is exactly how historical arguments proceed. In legal and historical reasoning, a source that repeatedly proves trustworthy on ordinary matters earns a presumption of credibility on more significant matters, unless there is strong reason to think otherwise. Undesigned coincidences contribute to that presumption for the New Testament writers. 2. The same narrative texture that supports mundane details also surrounds the miracle claims. The Gospels do not switch styles between non-miraculous and miraculous episodes. The same realism, geographical specificity, and interlocking with other accounts continue when they describe Jesus’ miracles and resurrection appearances. If the authors are careful and well-informed about crucifixion, people, and places, it is less plausible that they become careless fabricators only at the miracle points. 3. Miracles can be historically supported if a theistic background is independently plausible. If God exists (as argued by cosmological, teleological, and moral arguments), then miracles are not ruled out in principle. In that context, showing that we have strong, reliable testimony for a purported miracle (such as the resurrection) becomes highly relevant and evidentially weighty. See also: • CE / Resurrection: Maximal Facts Argument • Natural Theology Arguments
+ You could probably find similar interlocking details in other religious writings. Undesigned coincidences are not unique to the New Testament, so they do not prove anything special.
1. If undesigned coincidences appear in other texts, they also count as evidence for reliability there. The argument form is general: where multiple sources exhibit genuine undesigned coincidences, that raises the probability that they are connected to real events. This is not special pleading for Christianity; it is a general historical principle. 2. The question is comparative strength and density of the pattern. The New Testament (especially Gospels and Acts with Paul’s letters) shows a rich network of such coincidences across multiple books, genres, and authors. To undercut their force, one would need to show a comparable, carefully-documented network in rival religious texts, not just assert that such a thing “could” exist. 3. In Christianity’s case, undesigned coincidences feed into a larger cumulative case. These coincidences do not stand alone. They join archaeological confirmation, early dating, external references, and the transformation of witnesses to support the reliability of the New Testament at precisely the points where the resurrection claim is anchored. The strength of the case lies in the convergence of all these lines of evidence.

Logic

Study of Reasoning and Argumentation

First Principles

(●) First principles in logic are the most basic foundational rules or assumptions upon which logical reasoning is built. These principles are considered self-evident and do not require proof within the system...they are the starting points for all logical arguments and deductions. The most commonly recognized first principles in classical logic are:

(●) The Law of Identity: Everything is identical to itself. Any object or statement is the same as itself. A=A "For the same thing to belong and not belong simultaneously to the same thing and in the same respect is impossible..." -Aristotle

(●) The Law of Non-Contradiction: A statement cannot be both true and false at the same time and in the same respect. This means that "A and not A" cannot both be true. ¬(A ∧ ¬A) "It is impossible for the same thing at the same time to belong and not to belong to the same thing and in the same respect." -Aristotle

(●) The Law of Excluded Middle: For any proposition, either that proposition is true, or its negation is true. This means that there is no third (middle) option between a statement being true or false. A ∨ ¬A "But on the other hand, there cannot be an intermediate between contradictories, but of one subject we must either affirm or deny any one predicate." -Aristotle

Aristotle, Metaphysics, Book IV

Deductive Arguments

(●) What Are Deductive Arguments?
Deductive arguments are a fundamental part of logical reasoning. In a deductive argument, the conclusion is intended to follow necessarily from the premises. This means that if the premises are true and the reasoning is valid, the conclusion must also be true.

(●) Key Features of Deductive Arguments

- Certainty: Deductive arguments aim for certainty, not just probability. If the logic is valid and the premises are true, the conclusion cannot be false.
- Validity: An argument is valid if the conclusion logically follows from the premises, regardless of whether the premises are actually true.
- Soundness: An argument is sound if it is valid and all its premises are actually true.

(●) Multiple Premises in Deductive Arguments
Unlike syllogisms, which always have exactly two premises, deductive arguments can have any number of premises. For example, a mathematical proof might use several established facts (premises) to reach a conclusion. The key is that the conclusion must logically follow from all the premises taken together.

Example with Multiple Premises:

(P1) All mammals are warm-blooded.
(P2) All whales are mammals.
(P3) All warm-blooded animals need oxygen.
(C) Therefore, all whales need oxygen.
Here, three premises are used to reach the conclusion.

So how are Syllogisms different?
What Is a Syllogism?
A syllogism is a special kind of deductive argument with a very specific structure. First formalized by Aristotle, syllogisms have been a foundation of logical thinking for centuries. They are designed to show how a conclusion necessarily follows from two premises.

The Structure of a Syllogism
A standard (categorical) syllogism consists of:

-Major premise: A general statement about a group or category.
-Minor premise: A statement about a specific member or subset of that group.
-Conclusion: A statement that follows from the two premises.

Each statement contains two of three terms:

-Major term: The predicate of the conclusion.
-Minor term: The subject of the conclusion.
-Middle term: The term that links the major and minor terms, appearing in both premises but not in the conclusion.

Example (Categorical Syllogism):
-All mammals are warm-blooded. (major premise)
-All whales are mammals. (minor premise)
-Therefore, all whales are warm-blooded. (conclusion)

-Major term: warm-blooded
-Minor term: whales
-Middle term: mammals

Rules of Syllogisms
To be valid, a syllogism must follow certain rules:
-It must have exactly three terms, each used consistently.
-The middle term must be distributed (refer to all members of its class) at least once.
-No term can be distributed in the conclusion unless it was distributed in the premises.
-It cannot have two negative premises.
-If a premise is negative, the conclusion must also be negative.
-No conclusion can be drawn from two particular premises.

(●) Types of Deductive Arguments
Deductive arguments come in several forms, each with its own rules and applications. Here are the main types:

1. Categorical Deductive Arguments
These use statements about categories or classes, such as "All A are B." Syllogisms are the classic example of categorical arguments, focusing on relationships between groups or sets.

Example:
All birds have feathers.
All robins are birds.
Therefore, all robins have feathers.

2. Propositional Deductive Arguments
These use logical connectives to relate whole statements (propositions), such as "and," "or," and "if...then." Common forms within propositional logic include:

- Modus Ponens:
If P, then Q.
P.
Therefore, Q.

- Modus Tollens:
If P, then Q.
Not Q.
Therefore, not P.

- Disjunctive Syllogism:
P or Q.
Not P.
Therefore, Q.
(Disjunctive arguments use "either...or" statements and are a subtype of propositional logic.)

- Hypothetical Syllogism:
If P, then Q.
If Q, then R.
Therefore, if P, then R.
(Hypothetical arguments use conditional "if...then" statements and are also a subtype of propositional logic.)

3. Modal Deductive Arguments
These involve concepts of necessity and possibility, using modal operators like "necessarily" and "possibly."

Example:
Necessarily, if it is a square, then it is a rectangle.
It is a square.
Therefore, it is necessarily a rectangle.

4. Mathematical Deductive Arguments
These use axioms, definitions, and theorems to reach conclusions. Mathematical arguments often employ both categorical and propositional logic, but are structured around mathematical principles.

Example:
A triangle has three sides.
Figure X is a triangle.
Therefore, Figure X has three sides.

(●) Why Are Deductive Arguments Important?
Deductive arguments are used in mathematics, science, law, computer science, and everyday reasoning. They help us build strong, reliable conclusions from established facts or principles. Understanding deductive arguments helps you think more clearly, spot errors in reasoning, and communicate your ideas more effectively.

Inductive Arguments

(●) What is Inductive Reasoning?
In an inductive argument, it's possible for the premises to be true and the conclusion still be false. The premises don't guarantee the conclusion, but instead make it more probable than its competitors. The evidence used "underdetermines" the conclusion, meaning it makes it likely or plausible, but not certain. A good inductive argument must have true premises that are more plausible than their contradictories, and be informally valid (avoiding fallacies). However, they are not assessed for formal validity because the premises don't necessitate the conclusion's truth.

Here's a key example:
- 1. Groups A, B, and C were similar people with the same disease.
- 2. Group A got a new drug, B got a placebo, C got no treatment.
- 3. Death rate was 75% lower in Group A than B and C.
- 4. Therefore, the new drug is effective.

The conclusion is likely true based on the evidence, but it's not guaranteed – perhaps luck or another factor caused the difference.

(●) How Do We Understand Inductive Reasoning?
Philosophers approach understanding inductive reasoning in different ways. Two prominent methods are:

1. Bayes's Theorem:
This approach uses the rules of probability calculus. Bayes's theorem provides formulas to calculate the probability of a hypothesis (H) given certain evidence (E), symbolized as Pr(H|E). Probabilities range from 0 (lowest) to 1 (highest), with values above 0.5 suggesting positive probability. The probability of a hypothesis given evidence depends on its intrinsic probability (its likelihood based on general background knowledge) and its explanatory power (how likely the evidence would be if the hypothesis were true). A challenge in philosophy is assigning precise numerical values to these probabilities, often relying on vague approximations. An "odds form" of the theorem can compare the probability of two competing hypotheses given the evidence.

2. Inference to the Best Explanation (IBE)
A perhaps more practically useful approach in philosophy is inference to the best explanation (Also sometimes called Abduction). This method involves starting with data that needs explaining, identifying a set of possible explanations ("a pool of live options"), and then selecting the explanation that, if true, would best explain the data. Several criteria are commonly used to determine which explanation is "best":

• Explanatory scope: Does it explain a wider range of data than rivals?
• Explanatory power: Does it make the observable data more likely than rivals?
• Plausibility: Is it implied by a greater variety of accepted truths and its negation by fewer?
• Less ad hoc: Does it involve fewer new, unsupported assumptions than rivals?
• Accord with accepted beliefs: When combined with accepted truths, does it imply fewer falsehoods than rivals?
• Comparative superiority: Does it significantly outperform its rivals across these criteria?

The neo-Darwinian theory of biological evolution is presented as a good example of IBE. Supporters argue that even though the evidence (like micro-evolutionary change) doesn't prove macro-evolutionary development, the theory is the best explanation for the data due to its scope, power, and other factors. Critics, however, argue that the perceived superiority of Darwinism only holds if the pool of possible explanations is artificially limited (e.g., to only naturalistic ones). If other hypotheses, such as intelligent design, are allowed, the picture changes. This debate itself illustrates how IBE works and how disagreements about the criteria or the pool of options can arise.

Symbolic Logic

(●) Symbolic logic is a subdiscipline of philosophy akin to mathematics that deals with the rules of reasoning. In symbolic logic, letters and symbols are used to stand for sentences and the words that connect them. This approach helps to make the logical form of a sentence clear without being distracted by its grammatical form, as sentences with different grammatical structures may still have the same logical form.

Here is a legend of some common symbols:

Letters (P, Q, R, S, etc.)
Meaning: These capital letters stand for any arbitrary sentences.
Example: In the argument "If today is Sunday, the library is closed. Today is Sunday. Therefore, the library is closed," we can let P = "Today is Sunday" and Q = "the library is closed".

Arrow (→)
Meaning: The arrow stands for the connecting words, "if . . . , then . . ." or it can be read as "implies". In a sentence of the form P → Q, P is the antecedent clause and states a sufficient condition of the consequent clause Q. Q is the consequent clause and states a necessary condition of the antecedent clause P. The clause that follows a simple "if" is symbolized P (sufficient condition), and the clause that follows "only if" is symbolized Q (necessary condition).
Example: The sentence "If John studies hard, then he will get a good grade in logic" can be symbolized as P → Q, where P = "John studies hard" and Q = "he will get a good grade in logic". The sentence "Extra credit will be permitted only if you have completed all the required work" can be symbolized as P → Q, where P = "You may do extra credit work" and Q = "You have completed the required work".

Negation (¬)
Meaning: This symbol stands for "not" and is the sign of negation.
Example: ¬Q is read as "Not-Q". If Q is the sentence "My roommate is sleeping in," then ¬Q is "My roommate is not sleeping in". ¬¬Q is logically equivalent to Q.

Conjunction (&)
Meaning: This symbol is read as "and". It symbolizes any conjunction, including words like but, while, although, whereas, and many other words when they function as conjunctions. For a conjunction P & Q to be true, both P and Q must be true.
Example: The sentence "Charity is playing the piano, and Jimmy is trying to play the piano" can be symbolized as P & Q, where P = "Charity is playing the piano" and Q = "Jimmy is trying to play the piano". The sentence "They ate their spinach, even though they didn’t like it" would be symbolized P & Q, where P symbolizes "They ate their spinach" and Q symbolizes "they didn’t like it".

Disjunction (v)
Meaning: This symbol is read as "or". A sentence composed of two sentences connected by "or" is called a disjunction. In order for a disjunction to be true, only one part has to be true (or both).
Example: The sentence "Either Mallory will carefully work on decorating their new apartment, or she will allow it to degenerate into a pigsty" can be symbolized as P v Q, where P = "Mallory will carefully work on decorating their new apartment" and Q = "she will allow it to degenerate into a pigsty". Note that in logic, both parts of a disjunction can be true.

Universal Quantification ((x))
Meaning: This symbol is used in first-order predicate logic to deal with quantified sentences, specifically those about all or none of a group. It can be read as "For any x, . . .". Universally quantified statements turn out to be disguised "if . . . , then . . ." statements. The variable 'x' can be replaced by any individual thing.
Example: The statement "All bears are mammals" can be symbolized as (x) (Bx → Mx), where Bx = "x is a bear" and Mx = "x is a mammal". This is read as "For any x, if x is a bear, then x is a mammal". A negative universal statement like "No goose is hairy" is symbolized by negating the consequent: (x) (Gx → ¬Hx), read as "For any x, if x is a goose, then x is not hairy".

Existential Quantification (∃x)
Meaning: This symbol is used in first-order predicate logic for statements about only some members of a group. It tells us that there really exists at least one thing that has the property in question. It may be read as "There is at least one ___ such that . . .". Existentially quantified statements are typically symbolized using & (conjunction), not → (conditional).
Example: The statement "Some bears are white" can be symbolized as (∃x) (Bx & Wx), where Bx = "x is a bear" and Wx = "x is white". This is read as "There is at least one x such that x is a bear and x is white". The statement "Some bears are not white" is symbolized as (∃x) (Bx & ¬Wx).

Necessity (□)
Meaning: This symbol is used in modal logic to stand for the mode of necessity. □P is read as "Necessarily, P" and indicates that the statement P is necessarily true (true in every possible world). □¬P indicates that P is necessarily false (false in every possible world).
Example: □P is read as "Necessarily, P". □¬P is read as "Necessarily, not-P".

Possibility (◊)
Meaning: This symbol is used in modal logic to stand for the mode of possibility. ◊P is read as "Possibly, P" and indicates that the statement P is possible (true in at least one possible world). ¬◊P is read as "Not-possibly, P," meaning it is impossible for P to be true.
Example: ◊P is read as "Possibly, P".

"Would" Counterfactual (□→)
Meaning: This symbol is used in counterfactual logic for conditional statements in the subjunctive mood that state what would happen if the antecedent were true. P □→ Q is read as "If it were the case that P, then it would be the case that Q".
Example: The conditional "If Oswald hadn’t shot Kennedy, then somebody else would have" is a "would" counterfactual. It would be symbolized using □→.

"Might" Counterfactual (◊→)
Meaning: This symbol is used in counterfactual logic for conditional statements in the subjunctive mood that state what might happen if the antecedent were true. P ◊→ Q is read as "If it were the case that P, then it might be the case that Q". It is defined as the contradictory of P □→ ¬Q. "Might" indicates a genuine, live option under the circumstances.

Study of Knowledge

Three Types of Knowledge

(●) Acquaintance Knowledge (Knowing-by-acquaintance): Knowing something because the object of knowledge is directly present to one’s consciousness. For example, Dan knows the ball in front of him because he sees it and is directly aware of it...he knows it by sensory intuition. In this context, intuition does not mean a guess or irrational hunch, but rather a direct awareness of something present to consciousness. People know many things by acquaintance or intuition, such as their own mental states (thoughts, feelings, sensations), physical objects they perceive through the five senses, and, according to some, even basic principles of mathematics. When asked how people know that 2 + 2 = 4 or that if it is raining outside then it must be wet outside, the answer seems to be that people can simply “see” these truths. This kind of “seeing” is often thought to involve an intuitional form of awareness or perception of abstract, immaterial objects and the relationships among them...such as numbers, mathematical relations, propositions, and the laws of logic. Thus, all these examples are arguably cases of knowledge by acquaintance.

(●) Procedural Knowledge (Knowing-how): The ability or skill to behave in a certain way and perform some task or set of behaviors. One can know how to speak Greek, play golf, ride a bicycle, or perform a number of other skills. Know-how does not always involve conscious awareness of what one is doing. Someone can learn how to do something by repeated practice without being consciously aware that one is doing the activity in question or without having any idea of the theory behind the practice. For example, one can know how to adjust one’s swing for a curve ball without consciously being aware that one’s stride is changing or without knowing any background theory of hitting technique.

(●) Propositional Knowledge (Knowing-by-description): This is knowledge of facts or truths, expressed in declarative sentences. For example, "I know that water boils at 100 degrees Celsius." It is the most discussed type in philosophy and is often analyzed as "justified true belief."

Moreland, James Porter. Philosophical Foundations for a Christian Worldview. 2nd ed. Downers Grove, IL: Inter-Varsity Press, 2017.

Justified True Belief (JTB)

(●) The Quest to Define Knowledge
Since the time of Plato, philosophers have debated the nature of propositional knowledge...what it means to truly "know" something. In his dialogue Theaetetus, Plato explored the idea that knowledge might be "true belief with an account," a view that later evolved into the well-known "justified true belief" (JTB) analysis.
"true judgment with an account"...is the closest to what later philosophers called "justified true belief." However, Plato ultimately finds problems with each definition and does not endorse any as a final answer in the dialogue.

(●) The Standard Definition: Justified True Belief (JTB)
The standard definition states that knowledge consists of three essential components: justification, truth, and belief. To say someone knows a proposition (for example, "milk is in the refrigerator") means that three conditions must be met: the proposition must be true, the person must believe it, and the belief must be justified.

(●) Truth as a Necessary Condition
For someone to know something, it must be true. It would be nonsensical to claim that someone knows a falsehood. However, truth alone is not enough for knowledge. There are countless truths that no one knows or has even considered.

(●) Belief as a Necessary Condition
In addition to truth, belief is required. If a person does not believe a proposition, it cannot be said that they know it. However, simply believing something does not make it knowledge, since people can believe many things that are not true.

(●) The Insufficiency of True Belief
Even when a belief is true, that alone does not guarantee knowledge. A person might believe something that happens to be true purely by chance, without any justification. For example, if someone randomly thinks, "It is raining in Moscow right now," and it happens to be true, this is not knowledge...just a lucky guess.

(●) The Role of Justification
What distinguishes knowledge from mere true belief is justification or warrant. Justification means having sufficient evidence, forming beliefs in a reliable way (such as through the senses or expert testimony), and having properly functioning intellectual faculties in a suitable environment. The difference between a true belief and knowledge is that knowledge requires this additional element of justification or warrant.

(●) The Tripartite Analysis
The traditional or standard definition of propositional knowledge can be summarized as follows:
A person S knows that P if and only if:
1. S believes that P.
2. P is true.
3. S is justified in believing that P at the time S believes it.
This tripartite analysis remains a foundational concept in the philosophical study of knowledge.

Plato, Theaetetus, in Plato: Complete Works, ed. John M. Cooper (Hackett, 1997). Moreland, James Porter. Philosophical Foundations for a Christian Worldview. 2nd ed. Downers Grove, IL: Inter-Varsity Press, 2017. Plantinga, Alvin. "Warrant and Accidentally True Belief." Analysis 57, no. 2 (1997): 140–145.
+ The Gettier Problem: You walk into your living room, look at the wall clock, see “3:43,” and form the belief “It’s 3:43.” Under normal circumstances, that’s a reliable way to tell the time, and in this case the belief is in fact true: it *is* 3:43. However, you don’t know that the clock actually stopped exactly 24 hours ago at 3:43 and has been frozen ever since. Had it stopped at 3:17 or 8:02, your “method” (glancing at the clock) would have delivered a false belief. So you have a "justified true belief" that still seems wrong to call “knowledge,” because the truth of your belief is heavily dependent on coincidence.
Alvin Plantinga’s diagnosis: proper function, maxi‑ vs mini‑environment, and warrant. Plantinga agrees that luck is the problem, but he gives a more fine‑grained account of where the luck enters. He says our cognitive faculties (vision, memory, basic reasoning, etc.) have a design plan: when they are functioning properly in the broad kind of world they were made for (call this the "maxi‑environment," our normal Earth‑like world), they tend to produce true beliefs. When those conditions are met, a belief has "warrant": the special positive status that, when present in enough degree, turns true belief into knowledge. However, each particular act of forming a belief also occurs in a much more specific "mini‑environment": not just "on Earth," but “looking at this particular clock, in this particular condition, at this particular moment.” Even inside a good maxi‑environment, some mini‑environments are "epistemically misleading": they are such that, given that very specific setup, your properly functioning faculties cannot be relied on to produce a true belief. Now compare two mini‑environments that share the same maxi‑environment and the same cognitive functioning: (1) the clock is working normally, and (2) the clock is stopped at 3:43. In both, you use the same cognitive process by glancing at the clock and reading the time. In (1), that process is 'reliably truth‑producing' in that mini‑environment: in nearby situations just like it (if you looked again, if you came in a minute earlier or later, etc.), the same method would very likely yield a true belief. So here your belief is not only justified and true; it also has a 'degree of warrant high enough' to qualify as knowledge. In (2), by contrast, the mini‑environment is misleading: in nearby situations where you use the same method on that same stopped clock, you mostly get false beliefs about the time. Plantinga’s added "Resolution Condition" says that in such a misleading mini‑environment your belief cannot have warrant in the degree required for knowledge, even if it happens to turn out true once. Thus, on his revised view, the same everyday method (checking a clock) yields 'knowledge' when the local environment supports its reliability, and yields only 'lucky true belief' when the local environment is epistemically hostile...even though your inner mental life may look the same in both cases. See also: • Philosophy / Epistemology: Warrant

Warrant

(●) From Justification to Warrant
Twentieth century epistemology was dominated by the “justified true belief” (JTB) model of knowledge. But after Gettier style counterexamples showed that justified true belief can still fall short of knowledge, many philosophers argued that something crucial was missing from the analysis. Alvin Plantinga’s notion of warrant is one influential attempt to supply that missing ingredient and to explain what, in addition to truth and belief, turns a mere true belief into knowledge.
Plantinga reserves the term “justification” for deontological or duty related notions (being blameless or responsible in believing), and uses “warrant” for the quality that actually makes a true belief into knowledge. On his view, a person can be justified yet still lack warrant if their faculties are not functioning in the right way or the environment is misleading.

(●) What Is Warrant?
Plantinga uses “warrant” for that special positive quality which, when added to truth and belief in sufficient degree, yields knowledge. True belief without warrant might be lucky, accidental, or unsupported. True belief with enough warrant is not just accidentally right; it is produced in the right way, by the right kinds of cognitive processes, in the right sort of situation.

(●) Proper Function and the Design Plan
On Plantinga’s account, a belief has warrant when it is produced by cognitive faculties (such as memory, perception, and reason) that are functioning properly, that is, according to a design plan, under conditions for which those faculties were designed. Proper function rules out malfunction (as in hallucination, severe cognitive damage, or pathological bias) and anchors knowledge in the normal operation of our intellectual equipment.

(●) The Right Environment
Proper function alone is not enough. Our faculties must also be operating in an environment similar to the one for which they were designed. Human vision, for example, is made for a world with normal lighting, ordinary distances, and reliable objects, not for distorted fun house mirrors or systematically deceptive laboratory setups. When the environment is too different from the one anticipated by the design plan, even properly functioning faculties may no longer reliably yield true beliefs.

(●) Aim at Truth and Sufficient Success
The design plan of our cognitive faculties is also aimed at truth. Under the right conditions, these faculties are successfully truth orientated. Warrant comes in degrees, depending on how well the faculties are functioning, how appropriate the environment is, and how truth conducive the processes are in that setting. When a belief is formed by properly functioning, truth aimed faculties in an appropriate environment and enjoys enough of this positive status, that belief is warranted.

(●) Maxi Environment and Mini Environment
Plantinga distinguishes between a broad “maxi environment” (the general kind of world in which our faculties are meant to operate) and the more specific “mini environments” in which particular beliefs are formed (for example, this specific room, this particular test, that specific instrument). A belief can be formed in the right kind of world overall yet still arise in a misleading local setup, a mini environment in which the usual methods are no longer reliably truth producing.

(●) Resolving Gettier Style Luck
Gettier examples show that justified true belief can occur in situations where the truth of the belief depends heavily on coincidence. Plantinga diagnoses these as cases where proper function and the broad environment may be fine, but the specific mini environment is epistemically hostile or deceptive. In such cases, the belief does not achieve the degree of warrant required for knowledge, even if it happens to be true and justified by the subject’s lights.

(●) Warrant and Knowledge
On Plantinga’s proposal, we can summarize knowledge as follows:
A person S knows that P if and only if:
1. S believes that P.
2. P is true.
3. S’s belief that P has enough warrant (is formed by properly functioning, truth aimed faculties, operating according to a good design plan, in an appropriate environment).
Warrant thus replaces bare “justification” as the crucial fourth factor that explains why some true beliefs are merely lucky while others rise to the level of genuine knowledge.

Socrates of Athens 470 – 399 BC

(●) Socrates was an Athenian philosopher who is widely regarded as one of the founders of Western philosophy. He wrote no philosophical texts himself; instead, his ideas and methods are known through the works of his students, especially Plato and Xenophon, as well as the playwright Aristophanes. Socrates is famous for his method of questioning (the Socratic method or elenchus), which sought to expose contradictions in his interlocutors’ beliefs and to stimulate critical thinking and self-examination. He focused on ethical questions and the pursuit of virtue, famously claiming that he knew nothing except his own ignorance. Socrates was tried and executed by the city of Athens on charges of impiety and corrupting the youth, choosing to die rather than renounce his philosophical mission.

(Q) "The unexamined life is not worth living." Source: Plato, Apology 38a

(Q) "I know that I know nothing." Source: Plato, Apology 21d (paraphrased; the exact phrase is "I am wiser than this man; it is likely that neither of us knows anything worthwhile, but he thinks he knows something when he does not, whereas when I do not know, neither do I think I know.")

Plato, Apology – Socrates’ defense speech at his trial, as recorded by Plato. Plato, Crito – A dialogue about justice and Socrates’ reasons for refusing to escape from prison. Xenophon, Memorabilia – A collection of recollections about Socrates’ conversations and character.

Plato of Athens 427 – 347 BC

(●) Plato was an Athenian philosopher, a student of Socrates and teacher of Aristotle, whose dialogues shaped the entire subsequent tradition of Western philosophy. Through dramatic conversations, he argued that beyond the changing world of sense experience there exists an intelligible, eternal order of Forms (or Ideas), culminating in the Form of the Good, which grounds truth, beauty, and moral value. He defended the immortality and accountability of the soul, the objectivity of moral norms, and the idea that a well‑ordered society must be governed by wisdom rather than mere power. Plato’s vision of a transcendent Good, his distinction between the visible and invisible realms, and his insistence that the soul is ordered to truth and righteousness provided powerful conceptual scaffolding later used by Christian thinkers (especially Augustine) to articulate doctrines of God as the supreme Good, the created/uncreated distinction, the immortality of the soul, and the moral structure of reality.

(Q) "This, then, which gives to the objects of knowledge their truth, and to the knower his power of knowing, you must say is the idea of the Good." Source: Plato, Republic VI, 508e–509a.

(Q) "When the soul inquires alone and by itself, it departs to that which is pure, ever existing, immortal and unchanging, and being akin to it, it always stays with it whenever it is by itself and can do so; then it ceases from its wandering and remains always the same with that which is the same." Source: Plato, Phaedo 79d–e.

(Q) "Evil cannot be done away with, for there must always remain something opposite to good; but it never has a place among the gods, only among mortal nature and this world of ours." Source: Plato, Timaeus 29e–30a (on the goodness of the divine craftsman and the disorder of the material world).

(Q) "The just man does not allow the diverse elements in his soul to meddle with one another, but he sets his own house in order and rules himself; he becomes his own friend and harmonizes the three parts of himself like three terms in a musical scale, the lowest and the highest and the middle, and all together he binds them into a unity." Source: Plato, Republic IV, 443d–e.

Plato, Republic – Especially Books VI–VII on the Form of the Good and the allegory of the cave, and Book IV on the just soul. Plato, Phaedo – Arguments for the immortality and purity of the soul and its orientation to the invisible, unchanging realm. Plato, Timaeus – A theologically suggestive account of a good divine craftsman ordering the cosmos. Plato, Symposium – Reflections on the ascent of love from bodily desire to contemplation of eternal Beauty.

Aristotle of Stagira 384 – 322 BC

(●) Aristotle, a student of Plato from the city of Stagira, became one of the most comprehensive and systematic thinkers in history. He developed formal logic, a detailed account of causality and change, and an ethics centered on virtue and human flourishing (eudaimonia). In metaphysics he distinguished between act and potency, substance and accidents, and argued for the existence of an unmoved mover: a necessary, eternal, immaterial source of all motion and order in the universe. In ethics and politics, he taught that human beings have a natural end and that moral and civic life should be ordered toward the cultivation of virtue. Aristotelian ideas about being, causality, teleology, and the highest good became foundational for classical Christian theism and natural law theory; theologians such as Thomas Aquinas drew extensively on Aristotle’s concepts of first cause, final causality, and virtue to articulate philosophical arguments for God’s existence, providence, and the objective moral law.

(Q) "There is something which moves without being moved, being eternal, substance and actuality; and this is what we call God." Source: Aristotle, Metaphysics XII.7 (1072a24–26).

(Q) "The good for man is an activity of the soul in accordance with virtue, and if there are more kinds of virtue than one, in accordance with the best and most complete." Source: Aristotle, Nicomachean Ethics I.7 (1098a16–18).

(Q) "Nature does nothing in vain." Source: Aristotle, Politics I.2 (1253a8–9) and throughout his works, expressing his teleological view that natural beings act for ends.

(Q) "One must begin by observing that the law is a rule of reason, and the function of the law is to prescribe the right education that makes us good." Source: Paraphrase of Aristotle’s teaching in Nicomachean Ethics II.1–2 and X.9, where he describes law as a rational guide ordered to virtue and the common good.

Epicurus of Samos 341 – 270 BC

(●) Epicurus was a Greek philosopher who founded one of the most influential schools of Hellenistic philosophy, Epicureanism. He taught that the highest good is pleasure, understood not as indulgence but as the absence of pain (aponia) and mental disturbance (ataraxia). To achieve this tranquility, Epicurus advocated a materialist metaphysics: the universe consists only of atoms and void, the soul is material and mortal, and the gods (if they exist) are distant and uninvolved in human affairs. He denied divine providence, final causality, and life after death, arguing that fear of the gods and death are the chief sources of human anxiety and should be dispelled through reason. Epicureanism represents a direct challenge to core Christian doctrines: it denies creation by a personal God, divine providence and judgment, the immortality of the soul, and the resurrection of the body. The Apostle Paul encountered Epicurean philosophers in Athens (Acts 17:18), and early Christian apologists consistently refuted Epicurean materialism, arguing instead for a rational Creator, moral accountability, and the hope of eternal life.

(Q) "Death is nothing to us. When we exist, death is not yet present, and when death is present, then we do not exist." Source: Epicurus, Letter to Menoeceus 125.

(Q) "Is God willing to prevent evil, but not able? Then he is not omnipotent. Is he able, but not willing? Then he is malevolent. Is he both able and willing? Then whence cometh evil? Is he neither able nor willing? Then why call him God?" Source: Attributed to Epicurus in later tradition (especially by Lactantius, On the Anger of God 13.20–21); the formulation is not found verbatim in Epicurus' surviving writings but reflects his argument that divine providence is incompatible with the existence of evil.

(Q) "The blessed and indestructible being of the divine has no troubles itself, nor does it cause trouble for anyone else, so that it is not affected by feelings of anger or gratitude. All such things are found only in what is weak." Source: Epicurus, Principal Doctrines 1 (from Diogenes Laertius, Lives of Eminent Philosophers X.139).

(Q) "We must free ourselves from the prison of everyday affairs and politics." Source: Epicurus, Vatican Sayings 58; reflects his teaching to "live hidden" (lathe biōsas) and withdraw from public life to cultivate tranquility.

Philo of Alexandria 20 BC – 50 AD

(●) Philo of Alexandria was a Hellenistic Jewish philosopher who lived in the city of Alexandria, Egypt. Born into a wealthy diaspora family and educated in both Jewish Scripture and Greek paideia, he developed a distinctive synthesis of Jewish scriptural exegesis with Greek philosophical traditions, especially Platonism and Stoicism, chiefly through allegorical interpretation of the Pentateuch. Philo treated the narratives of the Torah as veils for universal truths about God, the soul, and virtue, insisting that Moses is the “summit of philosophy” and that Greek philosophers only glimpsed what the Law reveals more fully. Central to his thought is the doctrine of the divine Logos: the Logos is God’s Word, Wisdom, and mediating power, the intelligible pattern of creation and the bridge between the utterly transcendent God and the created order. His use of Logos language, his account of an utterly transcendent yet provident God, and his attempt to show the rationality of biblical faith later provided early Christian theologians with categories for articulating the doctrine of the Logos.

(Q) "For God, being one, has many powers; and the chief of them all is the Logos, by whom the whole world was fashioned." Source: Philo, On the Confusion of Tongues 146–147 (summarizing his description of the Logos as God’s chief power and instrument of creation).

(Q) "Let us learn that there is one world, one God, one providence, and one law, the common reason of all intellectual and rational beings." Source: Philo, On the Creation of the World 3–4 and related passages, where he stresses the unity of God, world, and rational law (logos) imprinted on creation.

(Q) "The Logos is the image of God, by whom the whole universe was formed." Source: Philo, On the Creation of the World 25–27 (paraphrasing his teaching that the visible cosmos is made after the intelligible pattern in the divine Logos, the image of God).

(Q) "The soul that loves God desires to flee from the body and the senses, and to dwell with Him alone who is incorporeal and invisible, apprehended only by the pure mind." Source: Philo, On the Migration of Abraham 10–12 and related allegorical passages on the soul’s journey from sense to contemplation of God through the Logos.

Jesus of Nazareth 6–4 BC – 30 AD

(●) According to the disciples and eye-witness biblical authors of the New Testament gospels, Jesus of Nazareth is the eternal Son of God who entered history as the long‑promised Messiah of Israel. Born in Bethlehem to the virgin Mary during the reign of Herod the Great, He grew up in Nazareth, worked as a carpenter, and began His public ministry around age thirty after being baptized by John the Baptist and affirmed by the Father and the Holy Spirit. Proclaiming the kingdom of God, Jesus taught with unique authority, performed miracles, healings, exorcisms, and gathered disciples, especially the twelve apostles, while calling people to repentance and faith in Him. He fulfilled Old Testament prophecy in His life, death, and resurrection, and confronted both legalistic religion and spiritual hypocrisy of the Jewish religious leaders. Under the Roman governor Pontius Pilate, Jesus was crucified outside Jerusalem as a substitutionary sacrifice for human sin, foretold in Scripture and grounded in real space‑time history as true historical event. On the third day, He physically rose bodily from the dead, appeared to many witnesses, and commissioned His followers to proclaim the gospel to all nations, then ascended into heaven, where He reigns as Lord and will visibly return to judge the living and the dead and fully establish His kingdom.

Paul the Apostle 5 – 64/67 AD

(●) Saul of Tarsus, later known as the apostle Paul, was a first‑century Jew from the city of Tarsus in Cilicia, a Roman citizen and a Pharisee trained under the respected rabbi Gamaliel. Zealous for the traditions of his ancestors, he initially viewed the early Christian movement as a dangerous heresy and actively persecuted followers of Jesus, approving of the stoning of Stephen and seeking to imprison believers. While traveling to Damascus to arrest Christians, he experienced a dramatic encounter with the risen Jesus, who appeared to him in blinding light, confronted his persecution, and commissioned him as a chosen instrument to carry the gospel to Gentiles, kings, and the people of Israel. After his conversion and baptism, Paul began preaching that Jesus is the Messiah and Son of God, eventually undertaking multiple missionary journeys throughout the Roman Empire, planting churches, training leaders, and enduring intense opposition, suffering, and imprisonment. He articulated key doctrines of the faith such as justification by grace through faith, union with Christ, and the inclusion of Gentiles in God’s people in letters to various churches and individuals. Many of these letters, including Romans, Corinthians, Galatians, and others, are preserved in the New Testament and have profoundly shaped Christian theology and practice. According to early tradition, Paul was eventually martyred in Rome during the reign of Nero, having fought the good fight, finished his course, and kept the faith.
