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. Plato lived in Athens, Greece. He wrote approximately two-dozen dialogues that explore core topics that are essential to all human beings.

Socrates is in prison, sentenced to die when the sun sets. In this final conversation, he asks what will become of him once he drinks the poison prescribed for his execution. Socrates and his friends examine several arguments designed to prove that the soul is immortal. This quest leads him to the broader topic of the nature of mind and its connection not only to human existence but also to the cosmos itself. What could be a better way to pass the time between now and the sunset? Plato lived in Athens, Greece.

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. Socrates and Meno are unable to identify teachers of ethics, and we are left wondering how such knowledge could be acquired. To answer that puzzle, Socrates questions one of Meno’s servants in an attempt to show that we know fundamental ideas by recollecting them.

Plato’s dialogues frequently cover several topics and show their connection to each other. The "Phaedrus" is a model of that skill because of its seamless progression from examples of speeches about the nature of love to mythical visions of human nature and destiny to the essence of beauty and, finally, to a penetrating discussion of speaking and writing. It ends with an examination of the love of wisdom as a dialectical activity in the human mind.

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. Is it better to suffer evil or to do evil? Is it better to do something wrong and avoid being caught or to be caught and punished? Is pleasure the same as goodness?

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. The more Socrates probes, the more absurd the responses from Hippias become.

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.

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. Plato lived in Athens, Greece. He wrote approximately two-dozen dialogues that explore core topics that are essential to all human beings.

Perception, memory, truth, and knowledge all play major roles in this dialogue. What is remarkable about Plato's treatment of those ideas is how contemporary are both the questions and the answers he puts in the mouths of his characters. Socrates is adamant in asserting that he does not know the answers but that his function is simply to help formulate and critically examine the doctrines presented by others.

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.
