Mohammed Arkoun was one of the most prominent and influential Arab intellectuals of his day. During a career spanning more than thirty years, he was revered as an outstanding research scholar, a bold critic of the theoretical tensions embedded within Islamic Studies and an outspoken public figure, upholding political, social and cultural modernism. This Festschrift honours Arkoun AZs scholarship, bringing together the contributions of eleven distinguished scholars of history, religious studies and philosophy. It offers a comprehensive selection of critical engagements with Arkoun AZs work, reflecting on his considerable influence on contemporary thinking about Islam and its ideological, philosophical and theological dimensions. Published in association with the Aga Khan University Institute for the study of Muslim Civilisations.
