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? What kind of education and training promotes both courage and goodness in people, whether they are young or old? Plato constantly presents courage as an essential quality for all who seek to live a good life, so what does it mean when even the bravest leaders of Athens cannot tell us what courage really is?
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?
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? As the characters in the dialogue pursue these questions, the foundations of ethics and the nature of the good life come to light.
The 'Republic' poses questions that endure: What is justice? What form of community fosters the best possible life for human beings? What is the nature and destiny of the soul? What form of education provides the best leaders for a good republic? What are the various forms of poetry and the other arts, which ones should be fostered, and which ones should be discouraged? How does knowing differ from believing? Several characters in the dialogue present a variety of tempting answers to those questions. Cephalus, Polemarchus, Thrasymachus, and Glaucon all offer definitions of justice. Socrates, Glaucon, and Adeimantus explore five different forms of republic and evaluate the merit of each from the standpoint of goodness. Two contrasting models of education are proposed and examined. Three different forms of poetry are identified and analyzed. The difference between knowing and believing is discussed in relation to the objects of each kind of thinking.
