A compact and lucid introduction to the work of Plato by an outstanding French scholar. Without attempting either an exposition or a full interpretation of Plato's philosophy, the author draws on four of the great dialogues (Theaetetus, Meno, Protagoras, Republic) for illustrative material. Emphasizing the union of politics and philosophy in Plato, Koyre shows how the reader must find his own solutions to the philosophical problems raised in the dialogues.
