Suhrawardi`s Criticism of The Philosophy of Ibn Sina

Ibn Suhrawardi’s Criticism of the Philosophy of Ibn Sina, Tahir Uluç conducts an epistemological discussion on the relation between philosophy and mysticism. In this context, he aims to go beyond the common opinion, which assumes that in Islamic thought, philosophy depends mostly on rational means in its quest for truth, theology rests primarily on revelation and Sufism on mystical experience and vision. Throughout his study, he investigates the following question: Are the legitimate domains of operation of philosophy and mysticism as clearly distinguished from each other as this assumption suggests, or do they share a common domain?
In answering this question, he suggests that Suhrawardi’s intention by this criticism is not to eradicate speculative philosophy in general and Peripateticism in particular, unlike the case in Ghazali, but to transform it into a theoretical basis upon which to build his own Illuminative (Ishraqi) system. In fact, Suhrawardi clarifies that one cannot understand the ?ikmat al-Ishraq, in which he provides a full exposition of his overall philosophical project unless one is well versed in the Peripatetic philosophy. 
In this perspective, Uluç demonstrates how the criticism of Peripateticism is an essential and integral part of Suhrawardi`s endeavor to build a theoretical basis for his Illuminative philosophy, which depends primarily on mystical experience and vision. Accordingly, this book has a twofold purpose. First, it examines from what epistemological point of view Suhrawardi finds the Peripatetic philosophy inadequate and on which principles he criticizes it. Secondly, it presents an in-depth analysis of how Suhrawardi, who regards himself as a philosopher and his endeavor as philosophical, transforms the Peripatetic philosophy into an instrument and prelude that would serve the Illuminative philosophy.
