Plato's Phaedo

Socrates is on trial for his life. He is charged with impiety and corrupting young people. He presents his own defense, explaining why he has devoted his life to challenging the most powerful and important people in the Greek world. The reason is that rich and famous politicians, priests, poets, and a host of others pretend to know what is good, true, holy, and beautiful, but when Socrates questions them, they are shown to be foolish rather than wise.

A dialogue between Socrates and Meno probes the subject of ethics. Can goodness be taught? If it can, then we should be able to find teachers capable of instructing others about what is good and bad, right and wrong, or just and unjust.

Phaedrus lures Socrates outside the walls of Athens, where he seldom goes, by promising to share a new work by his friend and mentor, Lysias, a famous writer of speeches. This dialogue provides a powerful example of the dialectical writing that Plato uses to manifest ideas that are essential to human existence and to living a good life. Phaedrus shows how oral and written forms of language relate to each other and to philosophy.

The Athenian court has found Socrates guilty and sentenced him to death. While he is waiting to be executed, his friend, Crito, comes to the prison to persuade him to escape and go into exile. Socrates responds by examining the essence of law and community, probing the various kinds of law and making distinctions that go far beyond the particular issue of whether or not Socrates should escape.

Laches, a general in the Athenian army, saw Socrates fight bravely in the battle of Delium. When he and Nicias, another general, are asked to explain the idea of courage, they are at a loss, and words fail them. How does courage differ from thoughtless and reckless audacity? Can a lion be said to be courageous? What about small children who have little idea of the dangers they face? Should we call people courageous who do not know whether their bravery will produce good or bad consequences?
