Tianyi Zhang offers in this study an innovative philosophical reconstruction of Shihāb al-Dīn al-Suhrawardī's (d. 1191) Illuminationism. Commonly portrayed as either a theosophist or an Avicennian in disguise, Suhrawardī appears here as an original and hardheaded philosopher who adopts mysticism as a tool for philosophical investigation.
Zhang makes use of Plato's cave allegory to explain Suhrawardī's Illuminationist project. Focusing on three areas--the theory of presential knowledge, the ontological discussion of mental considerations, and Light Metaphysics--Zhang convincingly reveals the Nominalist and Existential nature of Illuminationism and thereby proposes a new way of understanding how Suhrawardī's central philosophical ideas cohere.
