The Place of Psychology according to Aristotle and Avicenna

A problem concerning Aristotle’s psychology asks where its right place of study is. Should it be studied in physics or in metaphysics or some part of it in physics and some other part in metaphysics? There are two views concerning the place of psychology according to Aristotle’s philosophy of science and both find evidences in Aristotle’s own books, but this article criticizes them and shows that in spite of the Aristotelian texts, one cannot consider psychology as a physical science. This paper tries to show that according to Aristotelian principles, psychology is a metaphysical science and Aristotle’s texts show nothing but the close relationship between psychology and physics. Likewise, although Avicenna himself puts the discussion of soul in his Physics but we try to show that according to him the right place of psychology is in another science.
