The eighteenth-century Enlightenment was one of the most exciting and significant currents of European culture. Battling against tyranny, ignorance and superstition, it formulated the ideals which still inform our society today: a belief in reason, criticism, freedom of thought, religion and expression, the value of science, the pursuit of progress. Enlightenment thinkers undermined the _ancien regime_ and provided the ideas for the French Revolution. Modern scholarship, however, has shown it was a more complex and ambiguous movement than commonly recognized. This book, now in a fully updated second edition, sympathetically explores the complexities of the Enlightenment. Synthesizing and evaluating the latest scholarship, it offers a new and comprehensive vision of this many-faceted movement.
