  The Ishraqi philosophy of which Shihab al-Din al-Suhrawardī (d. 1191) is considered the founder, has intuition as the basis of its epistemology, at least in  theory.[2] Illumination (ishraq in Arabic), in a word, describes the event, which many speakers of English would also call intuition, which yields knowledge swiftly and certainly. Intuition plays a major role in al-Talwīḥāt, which is considered to be one of Suhrawardi’s more peripatetic writings. It is not surprising, then, that Ibn Kammuna frequently mentions intuition in his commentary to al-Talwīḥāt. It should be borne in mind, though, that true to his role as commentator, Ibn Kammuna will as a rule try to flesh out and expand upon Suhrawardi’s intentions, rather than expressly developing his own ideas.
