First published in 1859, John Stuart Mill's On Liberty is an exhaustive exploration of social and civic liberty, its limits, and its consequences. Mill's work is a classic of political liberalism that contains a rational justification of the freedom of the individual in opposition to the claims of the state.

This expanded edition of John Stuart Mill's Utilitarianism includes the text of his 1868 speech to the British House of Commons defending the use of capital punishment in cases of aggravated murder. The speech is significant both because its topic remains timely and because its arguments illustrate the applicability of the principle of utility to questions of large-scale social policy.

John Stuart Mill (1808-1873) was a torchbearer for liberal thought in the 19th century, including liberty of the individual and freedom of speech, and he championed women's suffrage in Parliament. A remarkable man - he learned Greek aged three and at eight had read Herodotus, Xenophon and Plato - he campaigned all his life for a just society. These two essays are his key works.

The foundation for all modern economic thought and political economy, The Wealth of Nations is the magnum opus of Scottish economist Adam Smith, who introduces the world to the very idea of economics and capitalism in the modern sense of the words.

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?

The leviathan is the vast unity of the State. But how are unity, peace, and security to be attained? Hobbes’ answer is sovereignty, but the resurgence of interest today in Leviathan is due less to its answers than its methods: Hobbes sees politics as a science capable of the same axiomatic approach as geometry.

The culture of “safety” and its intolerance of opposing viewpoints has left many young people anxious and unprepared for adult life. Lukianoff and Haidt offer a comprehensive set of reforms that will strengthen young people and institutions, allowing us all to reap the benefits of diversity, including viewpoint diversity. This is a book for anyone who is confused by what’s happening on college campuses today, or has children, or is concerned about the growing inability of Americans to live and work and cooperate across party lines.

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.

David Hume's Dialogues Concerning Natural Religion had not yet been published when he died in 1776. Even though the manuscript was mostly written during the 1750s, it did not appear until 1779. The subject itself was too delicate and controversial, and Hume's dialectical examination of religious knowledge was especially provocative. What should we teach young people about religion? The characters Demea, Cleanthes, and Philo passionately present and defend three sharply different answers to that question.

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, and which ones should be fostered and which ones should be discouraged? How does knowing differ from believing?

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.

Kant published this work in 1795, during the aftermath of the American Revolution and the French Revolution. The high hopes of the European Enlightenment had been dampened by the Reign of Terror in which tens of thousands of people died, and the perpetual cycle of war and temporary armistice seemed to be inescapable. Kant's essay is best known as an early articulation of the idea of a league of nations that could bring an end to all hostilities. Today, the United Nations continues to pursue that dream, but lasting peace still seems to be wishful thinking.

Thomas Paine published Common Sense in 1776, a time when America was a hotbed of revolution. The pamphlet, which called for America's political freedom, sold more than 150,000 copies in three months. Paine not only spurred his fellow Americans to action but soon came to symbolize the spirit of the Revolution itself. His persuasive pieces, written so elegantly, spoke to the hearts and minds of all those fighting for freedom from England.

“The problem of the twentieth century is the problem of the color line,” writes Du Bois, in one of the most prophetic works in all of American literature. First published in 1903, this collection of 15 essays dared to describe the racism that prevailed at that time in America—and to demand an end to it. Du Bois’ writing draws on his early experiences, from teaching in the hills of Tennessee, to the death of his infant son, to his historic break with the conciliatory position of Booker T. Washington.

The Vision of the Anointed is a devastating critique of the mindset behind the failed social policies of the past thirty years. Thomas Sowell sees what has happened not as a series of isolated mistakes, but as a logical consequence of a vision whose defects have led to disasters in education, crime, family disintegration, and other social pathology. In this book, "politically correct" theory is repeatedly confronted with facts-and sharp contradictions between the two are explained in terms of a whole set of self-congratulatory assumptions held by political and intellectual elites.
