This is the slyest, and therefore smartest, assessment of Islamic fundamentalism currently available. The author, a prolific Lebanese political theorist, has offered in this, his fourth monograph on the subject, a well-argued, highly original thesis. Moussalli asks one basic question: does Islamic fundamentalism have a philosophical basis? “Yes, it does,” he replies, “but it is not the same basis for all Islamic fundamentalists.” He then proceeds to demonstrate how particular Islamic fundamentalist theorists have addressed issues such as ideology and knowledge, society and politics, from their own philosophical perspective. The argument is markedly tilted toward politics, as each of the six chapters examines either a facet of political philosophy or the discourse of a particular theorist on the Islamic state. The first three chapters are framed as general overviews, first of the fundamentalism–modernism dyad, then of the epistemological divide between divine revelation and human reason, and finally of the discursive dichotomy between the Islamic state and democratic pluralism. The next three chapters shift to dominant theorists, the three “heroes” of Islamist ideology. Chapter 4 examines Hasan al-Banna on the Islamic state; Chapter 5, Sayyid Qutb. Chapter 6 takes up the most prominent current Islamist: Hasan al-Turabi. Not since Hamid Enayat's Modern Islamic Political Thought (Texas, 1982) has any scholar made such a comprehensive effort to trace the patterns of similarity—and the evidence of conflict and disagreement—among the major ideologues of Islamic fundamentalism.
