SEP — Plato (Kraut)

Richard Kraut’s survey entry in the Stanford Encyclopedia of Philosophy; first published 2004, substantively revised 24 April 2026. T1, on the same footing as sep-epistemology: a peer-reviewed reference entry by a specialist, with a dated revision history.

What it establishes

• The man. plato (429?–347 BCE), an Athenian of high status who “transformed the intellectual currents with which he grappled.” Kraut’s framing is strong: philosophy as a systematic examination of ethical, political and metaphysical questions is largely his invention.
• The forms. Observable reality is defective; a “more real and perfect realm” holds eternal, unchanging entities — Beauty, Goodness, Justice — outside space and time, serving as paradigms for the sensible world.
• The dialogues, and their traditional grouping. Nearly everything survives as dialogue, with Socrates as principal speaker (absent only in the Laws). Early or “Socratic” works (Euthyphro, Laches, Protagoras) are short and refutative; the middle period carries the theory (Phaedo, Republic, Symposium); the late group is linked stylometrically (Sophist, Statesman, Timaeus, Laws).
• Socrates as a moving target. He was a real person, and Plato’s portrayal changes: the early dialogues sit closer to the historical figure, the later ones use “Socrates” to carry Plato’s own positions.

The methodological claim

Kraut rejects the minimalist reading — the idea that a dialogue’s author asserts nothing and the reader should only report what characters say. His formulation: “penetrating the mind of Plato and comprehending what his interlocutors mean by what they say are not two separate tasks but one.”

That bears directly on how this spoke reads its own sources. A dialogue is an argument staged between positions, and refusing to attribute a view to its author is a decision about interpretation, not an abstention from one.
