Justified True Belief

(●) 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.
