Born out of the political turmoil of the English Civil War, Leviathan stands out as one of the most in influential political and philosophical texts of the 17th century. It argues for the restoration of the monarchy in light of the republic and calls for a commonwealth ruled by an authoritative, autocratic figure with absolute sovereignty. This would put an end to all controversy, war, and fear and establish peace via social contract.

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.

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.

Von einem Moment zum anderen verändert sich das Leben des Einzelgängers Antoine Roquentin radikal: Nichts ist mehr selbstverständlich, alles wird ihm zur Qual. Sämtliche Menschen und Gegenstände um ihn herum lösen einen unbestimmten Ekel in ihm aus. Um eine Erklärung dafür zu finden, beginnt er, sich minutiös zu beobachten. Und schließlich wird ihm klar: Es ist die Existenz an sich und die Zufälligkeit des Seins, die seinen Ekel verursachen.

Friedrich Nietzsche, 1844-1900, gilt als einer der bedeutendsten Philosophen des ausgehenden 19. Jahrhunderts. "Also sprach Zarathustra", das philosophische Werk über die Suche nach dem Übermenschen, ist zweifellos Nietzsches persönlichstes Werk...

Bertrand Russell's A History of Western Philosophy serves as the perfect introduction to its subject; it remains unchallenged as the greatest account of the history of Western thought. Charting philosophy's course from the pre-Socratics up to the early twentieth century, Russell relates each philosopher and school to their respective historical and cultural contexts, providing erudite commentary throughout his invaluable survey.

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 Critique of Pure Reason is a work that examines the faculty of reason and the qualities inherent in human thought. Before this time the influence of the knower on that which was sought to be known was not considered in a thorough and developed manner. Kant attempted with this critique to establish a limit to the knowable based on the nature of human cognition. His work was an attempt to address the failings in philosophy and metaphysics and provide a solid foundation for the proper use of reason to expand knowledge.

"Denn das Christentum ist eine Idee und als solche unzerstörbar und unsterblich wie jede Idee. Was ist aber diese Idee? Eben weil man diese Idee noch nicht klar begriffen und Äußerlichkeiten für die Hauptsache gehalten hat, gibt es noch keine Geschichte des Christentums." (Heinrich Heine: Geschichte der Religion und Philosophie in Deutschland)

What is life? What is my place in it? What choices do these questions obligate me to make? More than a half-century after it burst upon the intellectual scene - with roots that extend to the mid-19th century - Existentialism's quest to answer these most fundamental questions of individual responsibility, morality, and personal freedom, life has continued to exert a profound attraction.

A Treatise of Human Nature is the first work ever published by David Hume, a man who revolutionized our understanding of philosophy. Hume was an advocate of the skeptical school of philosophy and a key figure in the Scottish Enlightenment. He looks at the nature of human experience and cognition, showing that philosophy and reason can only be reflections of our nature.

In The Righteous Mind, social psychologist Jonathan Haidt explores the origins of our divisions and points the way forward to mutual understanding. His starting point is moral intuition - the nearly instantaneous perceptions we all have about other people and the things they do. These intuitions feel like self-evident truths, making us righteously certain that those who see things differently are wrong. Haidt shows us how these intuitions differ across cultures, including the cultures of the political left and right.

The Age of Reason is a work by English and American activist Thomas Paine, arguing for the philosophical position of deism. It follows in the tradition of 18th-century British deism, and challenges institutionalized religion and the legitimacy of the Bible.

Published anonymously on January 10, 1776, Thomas Paine's legendary work made the case for American independence. An immediate sensation across the thirteen colonies, Common Sense extolled Paine's belief that government should be simple and represent the will of the people, acting not as an oppressor but as a body to protect society. His clear and persuasive argument appealed to the common people, impressing on them the importance of secession from Great Britain.
