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.

First published in 1859, John Stuart Mill's On Liberty is an exhaustive exploration of social and civic liberty, its limits, and its consequences.

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.

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.

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.

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.

Hayek gives the main arguments for the free-market case and presents his manifesto on the "errors of socialism." Hayek argues that socialism has, from its origins, been mistaken on factual, and even on logical, grounds and that its repeated failures in the many different practical applications of socialist ideas that this century has witnessed were the direct outcome of these errors. He labels as the "fatal conceit" the idea that "man is able to shape the world around him according to his wishes."

"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)
