Problem of Union of Intelligent and Intelligible in Avicenna's Transcendental Thought

Unity of intelligent and intelligible has been one of the significant and controversial issues during history of philosophical thought, some have denied it and some has admitted. Two approaches can be found in Avicenna’s works, one is against and another is proponent. The big question is” has Avicenna’s thought been bewildered and contradicted?” There are many responses to this question. According to the authors, we need to distinguish his outline into two vertical approaches and then the formal contradiction will be perished. We must make a distinction between his peripatetic and transcendental viewpoint. Accordingly, his thought has developed from peripatetic to transcendental philosophy and his approach to this subject has completely changed. In this research, many evidences have been presented to show that Avicenna has been proponent of identity of intelligent and intelligible.
