The French Counter-Enlightenment and the Making of Modernity

Critics have long treated the most important intellectual movement of modern history–the Enlightenment–as if it took shape in the absence of opposition. In this groundbreaking new study, Darrin Mc Mahon demonstrates that, on the contrary, contemporary resistance to the Enlightenment was a major cultural force, shaping and defining the Enlightenment itself from the moment of inception, while giving rise to an entirely new ideological phenomenon-what we have come to think of as the "Right." Mc Mahon skillfully examines the Counter-Enlightenment, showing that it was an extensive, international, and thoroughly modern affair.
