Plato's Socrates, in prison and being urged to flee execution, raises in acute form, and for the first time in European thought, a central question: is it right to disobey the state? Socrates' controversial answer in Crito has generated much contemporary literature, but no English commentary of the Greek text for seventy-five years. This new edition aims to provide an up-to-date literary and philosophical analysis suitable for a wide range of readers, including those with post-beginners Greek. It represents an ideal introduction, not only to the social and philosophical world of Classical Greece, but also to the personality of one of its greatest thinkers.
