The trial of Socrates is one of the most famous of history. He was adjudged to be guilty, and sentenced to death. Though he could easily have escaped from Athens with the help of friends eager to help, he explains in The Crito that it would be opposed to everything he stood for to run away, that he would abide by the decision.
This dialogue of Plato, who wrote from the position of an observer at the trial, is the most revealing of the innermost mind of one of the greatest thinkers in human history. His technique during the trial, if representative of his teaching, remains with us today as "the socratic method." On the other hand, we may have Plato to thank for that. Since Socrates himself never wrote anything, or nothing has come down in history as his own writing, we must take Plato's word for it.
The Crito is another good example of the Socratic dialogue, leading from one point to another in the pursuit of truth.

Plato was a follower of Socrates, and later developed his own philosophy of Idealism, which then inspired the Neo-Platonists. Alfred North Whitehead has remarked that all of philosophy since then has been as footnotes to Plato. Plato's series of dialogues featuring Socrates may reflect more Plato's thinking than Socrates', but that is an ongoing discussion among philosophers.
