A view of Islam as a religion of political extremism, containing the seeds of its own politicization in a manner inherently incompatible with much of the Western world, has gradually become well entrenched in Western policy circles… In this erudite and powerful book, Olivier Roy persuasively challenges such ahistoricism. Roy…uses his wide-ranging and detailed knowledge of the Muslim world to present a reading of contemporary Islamic movements that provides an important corrective to such gross simplifications. The argument is all the more pertinent at a time when well-known American political scientists see global politics reduced to a ‘clash of civilizations.’ …[This] is a forceful work—an eloquent contribution to an important current debate by a scholar with long experience in the world of political Islam.

Olivier Roy’s examination of ‘political Islam’ has already had an important impact on the study of Islamism. His analysis is carefully defined and clearly presented… Roy’s conclusions are…sophisticated and nuanced. He argues that a particular type of Islamist program has failed and been replaced, not by a non-Islamic mode of thought, but by a different Islamic approach… This book is essential reading for all interested in the late 20th century evolution of movements of religious activism and revival… The issues that [Roy] raises—regarding the nature of Islamist movements and their relationships with modern institutions and concepts—must be dealt with.

- John O. Voll, Middle East Journal

Roy perceptively argues that the attempt to create a universal Islamist state is doomed to failure because of the conflicts between Sunni and Shia forms and other ethnic differences in the Islamic world. His is a keen, timely study; highly recommended.
