The death of Henry Corbin shortly before the Islamic Revolution in Iran prompted speculation about how he might have viewed the Revolution and the subsequent establishment of a Shiʿite government. His followers have varied widely in their responses to radical Islamism: some have distanced themselves from political discussions, others have explicitly dissociated Corbin’s teachings from Islamism, while a few attempted to align his interpretations with support for the Islamic government. This study delves into the tension between Corbin’s envisioning of Iranian Islam and the emergence of radical Islamism in postrevolutionary Iran, with a particular focus on Daryush Shayegan, a prominent Iranian philosopher. It also examines the perspectives of influential figures such as Michel Foucault and Christian Jambet on this topic. The chapter further explores Shayegan’s profound engagement with Corbin’s ideas, including the imaginal world, a critique of the historicization of spirituality, and a call for a revival of authentic Iranian traditions. In his writings after the Revolution, Shayegan critiqued the “ideologization of religion,” which he considered a consequence of the historicization and secularization of tradition. Through an analysis of Shayegan’s works, this chapter assesses the influence of Corbin’s interpretation of Iranian Islam on postrevolutionary discourse surrounding political Islam.
