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?

After more than 2,300 years, the Greek philosopher Aristotle still remains one of the most influential thinkers who has ever lived. There was hardly any field of human knowledge in existence during his day in which he did not make a major contribution. Additionally, he probed areas which were never before examined. Indeed, one could make the claim that no individual person has ever known as much about this world as Aristotle. His analyses of zoology and logic paved the way for modern forensic techniques, and for which every scientist down to this day owes him a debt of gratitude.

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.

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.

Plagued with doubt and uncertainty in sensory knowledge, Descartes is struck with the idea that everything he knows is false. He considers the possibility that he has been deceived by an 'evil demon' and is left with nothing to lean on, until he arrives at the phrase 'cogito ergo sum' ('I think, therefore I am'). Among the most quoted philosophical works in history, Meditations on First Philosophy and Discourse on the Method together display the full workings of Descartes' skeptical method and the formation of his famous phrase.

Aristotle's Nicomachean Ethics, said to be dedicated to Aristotle's son, Nicomachus, is widely regarded as one of the most important works in the history of Western philosophy. Addressing the question of how men should best live, Aristotle's treatise is not a mere philosophical meditation on the subject, but a practical examination that aims to provide a guide for living out its recommendations.

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.

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.

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.

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.

The Prince is a treatise that systematically charts the best strategies for successful governing. It unapologetically places realism above idealism, showing would-be kings how to get what they want while appearing to be generous and honourable, and advocates that the means — cruelty, duplicity and horror —justify the ends of secure monarchical rule. But it can also be read as the work of a secret republican subtly undermining the despotism of the ruling Medici family.

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.

Benedict de Spinoza's Ethics, first published in 1677, constitutes a major systematic critique of the traditional and religious foundations of philosophical thought. In it, Spinoza follows a logical step-by-step format consisting of definitions, axioms, propositions, proofs, and corollaries to create a comprehensive inquiry into the truth about God, nature, and humans' place within the universe. From these broad metaphysical themes, Spinoza derives what he considered to be the highest principles of religion and society and lays out an ethical system in which reason is the supreme value.

Written after the capture of Rome in 410 by Alaric, King of the Visigoths, St Augustine's City of God was intended as a response to pagan critics who blamed Christianity for this brutal defeat. Augustine attacks ancient pagan beliefs and relates the corruption and immorality that led to Rome's downfall, which began before Christ, before reaching his main argument: that the City of Man is perishing and only the Heavenly City of God will endure.

In The WEIRDest People in the World, Joseph Henrich draws on cutting-edge research in anthropology, psychology, economics, and evolutionary biology to explore these questions and more. He illuminates the origins and evolution of family structures, marriage, and religion, and the profound impact these cultural transformations had on human psychology. Mapping these shifts through ancient history and late antiquity, Henrich reveals that the most fundamental institutions of kinship and marriage changed dramatically under pressure from the Roman Catholic Church.

Rousseau's Social Contract remains, after a quarter of a millennium, one of the most controversial texts in the history of political philosophy, variously seen as a model for participatory democracy, a blueprint for totalitarianism, and several points in between. In addition to Rousseau’s magnum opus, this production includes an introduction by George Douglas Howard Cole, an English political theorist, economist, writer and historian. Also included are three discourses that Rousseau composed apart from The Social Contract.

最大多数の最大幸福をめざす功利主義は目先の快楽追求に満足しないソクラテスの有徳な生き方と両立する。人間生活全般の根本原理として個人や社会が正義とともに個性や人類愛を尊重するよう後押しする功利主義
