Man is born free, and everywhere he is in chains. In The Social Contract, Rousseau explores the concept of freedom and the political structures that may enable people to acquire it. He argues that the sovereign power of a state lies not in any one ruler but in the will of the general population. Rousseau argues that the ideal state would be a direct democracy where executive decision making is carried out by citizens who meet in assembly, as they would in the ancient city-state of Athens.

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.

Discourse on the Origin and Basis of Inequality Among Men by the philosopher Jean-Jacques Rousseau was originally written for an essay competition run by the Dijon Academy of Arts and Sciences in 1754. The question was, "What is the origin of inequality among men, and is it authorized by the natural law?" Rousseau's text is divided into four main parts: a dedication, preface, an extended inquiry into the nature of the individual, and another inquiry into the evolution of the human species within society.

Published four years after Rousseau's death, Confessions is a remarkably frank and honest self-portrait, described by Rousseau as "the history of my soul". From his idyllic youth in the Swiss mountains, to his career as a composer in Paris and his abandonment of his children, Rousseau lays bare his entire life with preternatural honesty.

On the Social Contract's appeal and influence has been wide-ranging and continuous. It has been called an encomium to democracy and, at the same time, a blueprint for totalitarianism. Individualists, collectivists, anarchists, and socialists have all taken courage from Rousseau's controversial masterpiece.

From the moment of its publication in 1748, The Spirit of the Laws proved to be a controversial work provoking widespread interest. Within three years it had been translated into various European languages - and was swiftly added to the List of Prohibited Books by the Roman Catholic Church. It is a remarkable book, a potpourri of observations and comments ranging far and wide over the social activities of mankind and it exerted a great influence on political leaders in the following decades.

In On the Genealogy of Morals, subtitled "A Polemic", Nietzsche furthers his pursuit of a clarity that is less tainted by imposed prejudices. He looks at the way attitudes towards 'morality' evolved and the way congenital ideas of morality were heavily colored by the Judaic and Christian traditions.

"Call me Ishmael." Thus starts the greatest American novel. Melville said himself that he wanted to write "a mighty book about a mighty theme" and so he did. It is a story of one man's obsessive revenge-journey against the white whale, Moby-Dick, who injured him in an earlier meeting. Woven into the story of the last journey of The Pequod is a mesh of philosophy, rumination, religion, history, and a mass of information about whaling through the ages.

Originally published anonymously, The Federalist Papers first appeared in 1787 as a series of letters to New York newspapers exhorting voters to ratify the proposed Constitution of the United States. Still hotly debated and open to often controversial interpretations, the arguments first presented here by three of America's greatest patriots and political theorists were created during a critical moment in our nation's history.

Immanuel Kant’s Critique of Pure Reason is a core text of modern philosophy. Presenting an examination of the nature of human reason, its central argument is that the way in which man perceives his environment is a direct consequence of the mind’s ability to act on this environment and convert it into something meaningful. The work brings together two opposing schools of philosophy—rationalism and empiricism—and proposes a third way, which came to be known as transcendental idealism. The work proved to be hugely influential, not least on Marx, Heidegger and Nietzsche.

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.

As intriguing today as when it was first published, Hume's An Enquiry Concerning Human Understanding is a fascinating exploration into the nature of human knowledge. Using billiard balls, candles, and other colorful examples, Hume conveys the core of his empiricism - that true knowledge can be gained only through sensory experience.

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.

On Anarchism provides the reasoning behind Noam Chomsky's fearless lifelong questioning of the legitimacy of entrenched power. In these essays, Chomsky redeems one of the most maligned ideologies, anarchism, and places it at the foundation of his political thinking. Chomsky's anarchism is distinctly optimistic and egalitarian. Moreover, it is a living, evolving tradition that is situated in a historical lineage; Chomsky's anarchism emphasizes the power of collective, rather than individualist, action.

Written in the form of a letter to a Frenchman, Edmund Burke's Reflections on the Revolution in France is an impassioned attack on the French Revolution and its hasty destruction of the Church, the old elites, and the Crown. Burke tackles the new republic and its allegiance to principles such as liberty and equality, as well as its failure to recognize the complexities of human nature, society, and wisdom accumulated over time, contending that gradual change and adjustment is far better than immediate upheaval.

Alexis de Tocqueville's renowned analysis of American democracy still has relevance today. In 1831 de Tocqueville was sent to America by the French government to study the U.S. penal system, but his real aim was to observe a democratic republic firsthand to see if such an entity could function with dignity and humanity. His travels, which took him to the cities of the Northeast, to the frontier and the Great Lakes, down the Mississippi and through the South, showed him a great deal about the United States. In 1834, he wrote Democracy in America, in which he examines the advantages and pitfalls of democracy, the conditions and conflicts among the races, and the movements that grip the country.

In 1831, Alexis de Tocqueville, a young French aristocrat and civil servant, made a nine-month journey through the eastern United States. The result was Democracy in America, a monumental study of the strengths and weaknesses of the nation’s evolving politics. His insightful work has become one of the most influential political texts ever written on America.

'The two foes of human happiness are pain and boredom.' Arthur Schopenhauer (1788-1860) was one of the most influential philosophers of the 19th century because his humanistic, atheistic, if pessimistic views chimed with a new secularism that was emerging from a Western society dominated by religion. Despite his rather forbidding image (and a few outdated views), he is one of the most approachable German philosophers, and this is certainly evident in these two key works, The Wisdom of Life and Counsels and Maxims.

This famous treatise began as a letter to a young French friend who asked Edmund Burke’s opinion on whether France’s new ruling class would succeed in creating a better order. Doubtless the friend expected a favorable reply, but Burke was suspicious of certain tendencies of the Revolution from the start and perceived that the revolutionaries were actually subverting the true "social order". Blending history with principle and graceful imagery with profound practical maxims, this book is one of the most influential political treatises in the history of the world.

Aristotle's Politics is a work of political philosophy. The end of Aristotle’s Nicomachean Ethics declared that the inquiry into ethics necessarily follows into politics, and the two works are frequently considered to be parts of a larger treatise, or perhaps connected lectures, dealing with the philosophy of human affairs. Aristotle is generally regarded as one of the most influential ancient thinkers in a number of philosophical fields, including political theory.

The Dialogues of Plato rank with the writings of Aristotle as the most important and influential philosophical works in Western thought. In them Plato cast his teacher Socrates as the central disputant in colloquies that brilliantly probe a vast spectrum of philosophical ideas and issues.

Xenophon was a Greek who admired and studied with Socrates. He marched with the Spartans and later was exiled from Athens. He wrote about the history of his times, the sayings of Socrates and about life in Greece. Edward Bysshe translated Xenophone's work in 1702. This translation has continued to have an excellent reputation. In this work Xenophon discusses the views of life taught by Socrates.

"Anarchy" (1907) is a political classic written by famous anarchist Errico Malatesta. "Anarchy is a word which comes from the Greek, and signifies, strictly speaking, without government: the state of a people without any constituted authority. Before such an organization had begun to be considered possible and desirable by a whole class of thinkers, so as to be taken as the aim of a party (which party has now become one of the most important factors in modern social warfare)."

How is it that the law enforcer itself does not have to keep the law? How is it that the law permits the state to lawfully engage in actions which, if undertaken by individuals, would land them in jail? These are among the most intriguing issues in political and economic philosophy. More specifically, the problem of law that itself violates law is an insurmountable conundrum of all statist philosophies. The problem has never been discussed so profoundly and passionately as in this essay by Frederic Bastiat from 1850. This essay might have been written today. It applies to our own time.

This pamphlet, first published in 1776, set in print the word every American was thinking about, but none dared say: independence! It was published anonymously in New York, selling 120,000 copies in the first 3 months and half a million in that same year. Its author, Thomas Paine, wrote in a language that could be understood by any reasonably literate colonist. But more important than it being so well received, is that it captured the American colonists' imaginations and was a primary catalyst to the independence movement in the United States. Noted American historian Bernard Bailyn called it "the most brilliant pamphlet written during the American Revolution, and one of the most brilliant ever written in the English language."

Dr. Arnn, president of Hillsdale College, reveals this integral unity of the Declaration and the Constitution. Together, they form the pillars upon which the liberties and rights of the American people stand. United, they have guided history's first self-governing nation, forming our government under certain universal and eternal principles. Unfortunately, the effort to redefine government to reflect "the changing and growing social order" has gone very far toward success.

Meditations is former U.S. President Bill Clinton's favorite book. This audio consists of a series of personal writings by Marcus Aurelius, Roman Emperor 161-180 AD, setting forth his ideas on Stoic philosophy.

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?

John Locke and his works - particularly An Essay Concerning Human Understanding - are regularly and rightly presented as foundations for the Age of Enlightenment. His primary epistemological message - that the mind at birth is a blank sheet waiting to be filled by the experiences of the senses - complemented his primary political message: that human beings are free and equal and have the right to envision, create and direct the governments that rule them and the societies within which they live.

Thomas Paine's The Age of Reason; Being an Investigation of True and Fabulous Theology, published in three parts from 1794, was a best seller in America, where it caused a short-lived deistic revival. Promoting a creator-God while advocating reason in the place of revelation, Paine’s controversial pamphlet caused his native British audience, fearing the results of the French Revolution, to receive it with more hostility than their American counterparts.

Discourse on the Origin and Basis of Inequality Among Men by the philosopher Jean-Jacques Rousseau was originally written for an essay competition run by the Dijon Academy of Arts and Sciences in 1754. The question was, "What is the origin of inequality among men, and is it authorized by the natural law?" Rousseau's text is divided into four main parts: a dedication, preface, an extended inquiry into the nature of the individual, and another inquiry into the evolution of the human species within society.

The Reveries of the Solitary Walker was one of the last works written by the French philosopher Jean-Jacques Rousseau (1712-1778) and was, in fact, not quite complete. It was published four years after his death and came quickly to be regarded as one of his most poetic works. It consists of 10 Walks (only the final ‘Walk’ was unfinished) during which he muses on a variety of topics including thoughts on issues which featured strongly in his notable life as a philosopher and commentator, including education and political philosophy.

Published four years after Rousseau's death, Confessions is a remarkably frank and honest self-portrait, described by Rousseau as "the history of my soul". From his idyllic youth in the Swiss mountains, to his career as a composer in Paris and his abandonment of his children, Rousseau lays bare his entire life with preternatural honesty.

For a world that over the past century has witnessed horrors the like of which could not have been imagined by earlier generations, Job’s cries of despair and incomprehension are all too recognisable. The visionary psychotherapist Carl Gustav Jung understood this and responded with this remarkable book, in which he set himself face to face with 'the unvarnished spectacle of divine savagery and ruthlessness'.

Immanuel Kant’s Critique of Pure Reason can lay claim to being the most important single work of modern philosophy, a work whose methodology, if not necessarily always its conclusions, has had a profound influence on almost all subsequent philosophical discourse. In this work Kant addresses, in a groundbreaking elucidation of the nature of reason, the age-old question of philosophy: “How do we know what we know?” and the limits of what it is that we can know with certainty.
