The Enlightenment shaped modernity. Western values of representative democracy and basic human rights and freedoms form an interlocking system that derives directly from the Enlightenment's philosophical revolution. This is uncontested--yet remarkably few historians or philosophers have attempted to trace the process of ideas from the political and social turmoil of the late eighteenth century to the present day. This is precisely what Jonathan Israel does in the third part of his revisionist series. He demonstrates that the Enlightenment was an essentially revolutionary process, driven by philosophical debate. From 1789, its impetus came from a small group of philosophe-revolutionnaires. Not aligned to any of the social groups represented in the French National Assembly, they nonetheless forged "la philosophie moderne"--in effect Radical Enlightenment ideas--into a world-transforming ideology that had a lasting impact in Latin America, Canada and eastern Europe as well as the countries from which it sprang. --

A leading historian reveals the radical origins of humanity's most cherished secular values Democracy, free thought and expression, religious tolerance, individual liberty, political self-determination of peoples, sexual and racial equality—these values have firmly entered the mainstream in the decades since they were enshrined in the 1948 U.N. Declaration of Human Rights. But if these ideals no longer seem radical today, their origin was very radical indeed—far more so than most historians have been willing to recognize. In A Revolution of the Mind , Jonathan Israel, one of the world's leading historians of the Enlightenment, traces the philosophical roots of these ideas to what were the least respectable strata of Enlightenment thought—what he calls the Radical Enlightenment. Originating as a clandestine movement of ideas that was almost entirely hidden from public view during its earliest phase, the Radical Enlightenment matured in opposition to the moderate mainstream Enlightenment dominant in Europe and America in the eighteenth century. During the revolutionary decades of the 1770s, 1780s, and 1790s, the Radical Enlightenment burst into the open, only to provoke a long and bitter backlash. A Revolution of the Mind shows that this vigorous opposition was mainly due to the powerful impulses in society to defend the principles of monarchy, aristocracy, empire, and racial hierarchy—principles linked to the upholding of censorship, church authority, social inequality, racial segregation, religious discrimination, and far-reaching privilege for ruling groups. In telling this fascinating history, A Revolution of the Mind reveals the surprising origin of our most cherished values—and helps explain why in certain circles they are frequently disapproved of and attacked even today.
