Description: This study is an intellectual biography of Muhammad al-Ghazali (1917-1996), one of most influential, yet understudied, Sunni Muslim thinkers of the twentieth century. Through an analysis of a range of never before utilized writings by al-Ghazali and his colleagues, this study charts his rise as a leading thinker in the Muslim Brotherhood during the 1940s, his subsequent clash and expulsion from the group in 1953, and his extensive post-Brotherhood career during the Nasser years.
