 Suhrawardi provides an original Platonic critique of the dominant Avicennan Peripateticism of the time in the fields of logic, physics, epistemology, psychology, and metaphysics. In so doing, he elaborates his own epistemological (logic and psychology) and metaphysical (ontology and cosmology) ishraqi notions, concepts and theories. He divided logic into three-parts, rejecting Avicenna’s Peripatetic essentialist definition, and reducing the number of forms of the syllogism. In physics, he rejected Avicenna’s hylomorphism, while bodies became magnitude with accidents.
