An Athenian philosopher and student of Socrates whose dialogues, nearly all of which survive, are the founding texts of the Western philosophical tradition. Plato wrote almost nothing in his own voice, instead staging Socrates in conversation with other Athenians on questions of justice, knowledge, love, and the soul. His theory of Forms holds that the changing things we perceive with the senses are imperfect copies of unchanging, non-physical Forms grasped by reason alone, so that a particular just act is just only by participating in the Form of Justice itself. Around 387 BCE he founded the Academy in Athens, an institution devoted to philosophical and mathematical inquiry that continued, with interruptions, for centuries, and that produced his most famous student, Aristotle. His Republic remains the most widely read work of political philosophy in the tradition he began.

Cross-Tradition Connections

Associated With

Al-Farabi, Philosophers

Al-Madina al-Fadila directly reworks the political philosophy of Plato's Republic for an Islamic context.

Critiqued Here

Aristotle, Philosophers

Aristotle, Plato's own student at the Academy, rejected the theory of Forms as an unnecessary duplication of the world, arguing that the form of a thing is realized within the thing itself rather than existing separately in an abstract realm.

In Branch

Influenced

Devotes a chapter of Representative Men (1850), "Plato; or, the Philosopher," to him.

Influenced By

Socrates, Philosophers

Plato was Socrates' student and cast him as the central speaker of nearly all his dialogues; this closes the gap of Plato carrying no teacher on record.

Quote
Few other authors in the history of Western philosophy approximate him in depth and range: perhaps only Aristotle (who studied with him), Aquinas, and Kant would be generally agreed to be of the same rank.

Quote, In Branch: Philosophy of Action, entry: Action, Introduction
There is a long-standing tradition in philosophy going back at least as far as Plato and Aristotle that recognizes an important distinction between the acts that (non-human) animals in general are capable of, and the special sorts of actions that human beings do intentionally, such as going to the store, making phone calls, protesting an injustice, or knitting a sweater.

In saying this, Plato regarded habituation as a mode of education and identified true beliefs about what is good and reasonable as important educational content.
