Written in Greek by an intellectual Roman emperor without any intention of publication, the Meditations of Marcus Aurelius offer a wide range of fascinating spiritual reflections and exercises developed as the leader struggled to understand himself and make sense of the universe. Spanning from doubt and despair to conviction and exaltation, they cover such diverse topics as the question of virtue, human rationality, the nature of the gods and Aurelius's own emotions.

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.

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.

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.

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.

‘It was a sweet finish after the bitter pills of floggings and bullets with which these same governments, just at that time, dosed the German working-class risings’. The Communist Manifesto is, perhaps surprisingly, a most engaging and accessible work, containing even the odd shaft of humour in this translation by Samuel Moore for the 1888 English edition.

On Liberty is a book by John Stuart Mill, one of the most celebrated philosophers on the subject of leadership and governing ideals. The book focuses on Mill's philosophy on utilitarianism which is one of his defining principles. The principles of the book are focused on developing a relationship between the ruling authority and liberty.

Continuing where Thus Spoke Zarathustra left off, Nietzsche's controversial work Beyond Good and Evil is one of the most influential philosophical texts of the 19th century and one of the most controversial works of ideology ever written. Attacking the notion of morality as nothing more than institutionalised weakness, Nietzsche criticises past philosophers for their unquestioning acceptance of moral precepts. Nietzsche tried to formulate what he called "the philosophy of the future".

The Theory of Moral Sentiments (1759) was the first major text by Adam Smith who, seven years later, was to publish what was to become one of the major economic classics, The Wealth of Nations (1776). However, Smith regarded The Theory of Moral Sentiments as his most important work because in it he identified the profound human instinct to act not necessarily in self-interest but through, as he phrased it, a ‘mutual sympathy of sentiments’.

In the first volume in the Penguin History of the United States series, edited by Eric Foner, Alan Taylor challenges the traditional story of colonial history by examining the many cultures that helped make America, from the native inhabitants from millennia past through the decades of Western colonization and conquest and across the entire continent, all the way to the Pacific coast.

In the early 1800s, three young men strode onto the national stage, elected to Congress at a moment when the Founding Fathers were beginning to retire to their farms. Daniel Webster of Massachusetts, a champion orator known for his eloquence, spoke for the North and its business class. Henry Clay of Kentucky, as dashing as he was ambitious, embodied the hopes of the rising West. South Carolina's John Calhoun, with piercing eyes and an even more piercing intellect, defended the South and slavery.

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 Athenian court has found Socrates guilty and sentenced him to death. While he is waiting to be executed, his friend, Crito, comes to the prison to persuade him to escape and go into exile. Socrates responds by examining the essence of law and community, probing the various kinds of law and making distinctions that go far beyond the particular issue of whether or not Socrates should escape.

The Gettysburg Address, delivered by Lincoln on November 19, 1863, in the aftermath of a narrow, bloody Union victory at the Battle of Gettysburg, is considered one of the greatest speeches in American history.

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.

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.

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.

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.

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.

Read by award-winning narrator Mike Vendetti, Common Sense is a pamphlet written by Thomas Paine in 1775-76 that inspired people in the Thirteen Colonies to declare and fight for independence from Great Britain in the summer of 1776. The pamphlet explained the advantages of and the need for immediate independence in clear, simple language. It was published anonymously on January 10, 1776, at the beginning of the American Revolution and became an immediate sensation.

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.

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.

Published in 1651, Leviathan is considered to be one of the most important works of political philosophy and a major contribution to the modern idea of central government. In the mid-17th century, England was going through a turbulent time of change and unrest, which likely shaped Hobbes' ideas on strong government. Thomas Hobbes established the social contract theory. He believed that self-government did not create the ideal state due to the human tendency to be self-serving, something he believed would eventually lead to chaos.

Lysander Spooner was one of slavery’s fiercest enemies. As a lawyer, he offered free legal services to escaped slaves, defending them in court. He advocated smuggling guns to slaves, with which to overthrow their masters, and take possession of their property. “Give the Slave-holders, then, a taste of their own whips.”

Utopia is the name given by Sir Thomas More to an imaginary island in this political work written in 1516. Book I of Utopia, a dialogue, presents a perceptive analysis of contemporary social, economic, and moral ills in England. Book II is a narrative describing a country run according to the ideals of the English humanists, where poverty, crime, injustice, and other ills do not exist.
