 Instructed in the Avicennan Peripatetic tradition, Suhrawardi studied the views of Aristotle, Plato, the Neoplatonists, and later philosophers (falasifa) who wrote in Arabic, notably Avicenna’s (d.1037) whose major works remained central. Work is still needed to assess the nature of the influence exerted on him by Avicenna’s other works, for instance, his Discussions (1992) and Notes on Aristotle’s De anima (1984), and by post-Avicennan philosophers, particularly Abu al-Barakat al-Baghdadi (d.ca.1165), the original yet eclectic critic of Avicenna’s logic, psychology and metaphysics, Fakhr al-Din al-Razi (d.1210), and the the innovative Ibn Sahlan al-Sawi (the logician) (d.ca. 1158).
