The Immateriality of Soul from Suhrawardi's Viewpoint

The immateriality of soul, as the most important subject in the knowledge of soul, was noticed by the great philosophers, including Plato, Plotinus and Ibn- sina (Avicenna). They separately propounded the new discussions and had innovations about the subject. Now, there is a question whether Suhrawardi, who is founder of Hekmat – al-Ishraq (a school of Islamic philosophy) and discussed about the Immateriality of soul, have a new innovation about it (especially because he propounded a theory named “The presence knowledge” that connected whit the nature of soul).We show in this paper that Suhrawardi had a new approach to this subject based on the "presence knowledge" theory as well as the previous philosopher's methods. In his mystical treatises, he uses a symbolic language to represent new approaches to this subject. In this relation, we can call him a hero of the philosophy of soul.
