Renowned as the chief challenger of traditional views of morality, man's freedom, and religion from 1650-1750, Benedict de Spinoza (1632-77) spread alarm and confusion throughout Europe through his writings. Theologians and rulers desperately sought to ban the spread of Spinozist ideas, and, in the post-Spinozist climate, eighteenth- century thinkers, often exasperated and perplexed, attempted to cope with the fallout from this intellectual explosion. The philosophical radicalism of Denis Diderot (1713-84), a French philosophe, and Gotthold Ephraim Lessing (1729-81), a German philosopher, well exemplifies the post-Spinozist mentality that permeated eighteenth-century thinking. As they grapple with the loss of intellectual, moral, and theological certainties, Diderot and Lessing re-work post-Spinozist ideas and in many instances elucidate even more radical ideas than Spinoza himself had envisaged.

This volume investigates the impact of the Radical Enlightenment on German culture during the eighteenth century, taking recent work by Jonathan Israel as its point of departure. The collection documents the cultural dimension of the debate on the Radical Enlightenment. In a series of readings of known and lesser-known fictional and essayistic texts, individual contributors show that these can be read not only as articulating a conflict between Enlightenment and Counter-Enlightenment, but also as documents of a debate about the precise nature of Enlightenment. At stake is the question whether the Enlightenment should aim to be an atheist, materialist, and political movement that wants to change society, or, in spite of its belief in rationality, should respect monarchy, aristocracy, and established religion. Contributors are: Mary Helen Dupree, Sean Franzel, Peter Höyng, John A. McCarthy, Monika Nenon, Carl Niekerk, Daniel Purdy, William Rasch, Ann Schmiesing, Paul S. Spalding, Gabriela Stoicea, Birgit Tautz, Andrew Weeks, Chunjie Zhang

Enlightenment Cosmopolitanism brings together ten innovative contributions by outstanding scholars working across a wide array of disciplines in the humanities and social sciences. Interdisciplinary in its methodology and compass, with a strong comparative European dimension, the volume examines discourses ranging from literature, historiography, music and opera to anthropology and political philosophy. It makes an original contribution to the study of 18th-century ideas of universal peace, progress and wealth as the foundation of future debates on cosmopolitanism. At the same time, it analyses examples of counter-reaction to these ideas and discusses the relevance of the Enlightenment for subsequent polemics on cosmopolitanism, including 21st-century debates in sociology, politics and legal theory.
