Book excerpt: Based on a series of lectures delivered at the University of Chicago 1945, Modern Trends in Islam analyzes the evolving religious beliefs of practicing Muslims during the author’s own time. It was one of the first texts in English to treat Islam not as an unchanging set of beliefs and practices but as a dynamic religion whose meaning is continually redefined by its adherents. In six chapters, this concise book covers Islam’s confrontation with Western Modernism in the first half of the twentieth century in realms of law, society, and religious thought. In doing so, these essays anticipate many of the tensions between progressivism and fundamentalism that have characterized Islamic life, thought, and politics over the last seventy years.
