Abstract

Some people consider Ibn-Sina a Peripatetic philosopher and merely a comentator of Aristotle's works.However even a facile study of the works of this eminent philosopher reveals that this is absolutely wrong.In fact, the differences between Ibn-Sina's theories and those of Aristotle are so great in number that we cannot even enumerate them in this paper.Nevertheless, it seems that towards the end of his short life, Ibn-Sina intended to found a new philosophical system, called "Oriental Wisdom", but he couldn't achieve this purpose due to his untimely death. Today the only available part of the book of "Oriental Wisdom" is the chapter on oriental logic.Therefore, the purpose of the wirter in this paper is to explore those issues which play a central role in Ibn-Sina's oriental thought and stand in opposition to the views of the Peripatetic philosophers, particularly Aristotle. Such issues include:1. Ibn-Sina and Aristotle's disagreement concerming the relationship between the soul and the body.2. Ibn-Sina and Aristotle's disagreement concerning the active intellect.3. The conjectural intellect and the sacred intellect, which are among Ibn-Sina's innovations.4. Ibn-Sina's gnostic disposition which is based on emananation and illumination from the outside and is in contradiction Aristotle's intellectual and senseless paganism.
