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 dramatic nature of Plato's dialogues is delightfully evident in Symposium. The marriage between character and thought bursts forth as the guests gather at Agathon's house to celebrate the success of his first tragedy. With wit and insight, they all present their ideas about love - from Erixymachus' scientific naturalism to Aristophanes' comic fantasy. The unexpected arrival of Alcibiades breaks the spell cast by Diotima's ethereal climb up the staircase of love to beauty itself.

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.

Gorgias of Leontini, a famous teacher of rhetoric, has come to Athens to recruit students, promising to teach them how to become leaders in politics and business. A group has gathered at Callicles' house to hear Gorgias demonstrate the power of his art. This dialogue blends comic and serious discussion of the best life, providing a penetrating examination of ethics.

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?

In Euthyphro, Socrates is on his way to the court, where he must defend himself against serious charges brought by religious and political authorities. On the way he meets Euthyphro, an expert on religious matters who has come to prosecute his own father. Socrates questions Euthyphro's claim that religion serves as the basis for ethics. Euthyphro is not able to provide satisfactory answers to Socrates' questions, but their dialogue leaves us with the challenge of making a reasonable connection between ethics and religion.

Socrates questions Ion, an actor who just won a major prize, about his ability to interpret the epic poetry of Homer. How does an actor, a poet, or any other artist create? Is it by knowing? Is it by inspiration? As the dialogue proceeds, the nature of human creativity emerges as a mysterious process and an unsolved puzzle.

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.

Aristotle's Poetics is best known for its definitions and analyses of tragedy and comedy, but it also applies to truth and beauty as they are manifested in the other arts. In our age, when the natural and social sciences have dominated the quest for truth, it is helpful to consider why Aristotle claimed poetry is more philosophical and more significant than history. Like so many other works by Aristotle, the Poetics has dominated the way we have thought about all forms of dramatic performance in Europe and America ever since.

Hippias of Elis travels throughout the Greek world practicing and teaching the art of making beautiful speeches. On a rare visit to Athens, he meets Socrates, who questions him about the nature of his art. Socrates is especially curious about how Hippias would define beauty. They agree that beauty makes all beautiful things beautiful, but when Socrates presses him to say precisely what he means, Hippias is unable to deliver such a definition.
