Abstract

Since one of the explicit differences between Avicenna and Mulla Sadra’s philosophical thought based on the important issue of ‘Motion’ specially ‘Substantial Motion’, and there’s complete difference in the debate, the author has tried to response the questions about the origins and theoretical basis of this difference and to find out which position and principle have been involved in this contrast. First part of the essay studies the difference between Avicenna and Mulla Sadra‘s essential position through analytical comparison of ‘Motion Premise’ in the thought of these two well-known philosophers. 1- Sadra’s perception of motion against Avicenna’s quiddity and category centered attitude. 2- Expanding of ‘Motion’ discussion from concretes to abstracts especially human soul. 3- Change in the position of’ Motion’ from the section of natural issues to the section of common affairs. By analytical studying of the mentioned points specially with meditating in Avicenna’s objections on ‘Substantial Motion’, we conclude that the difference of these two well-known philosophers in the premise of ‘Substantial Motion’ originates from the most important philosophical position that is called ‘Principal of Existence’ or ‘Priority of quiddity. On this basis of these facts and despite of all denials and doubts of some other thinkers in Avicennas’s ‘Principle of priority of quiddity’ thought, based on this  philosophical analysis , it can be explicitly seen the consideration of ‘priority of quiddity, which at least can end  the doubts about ‘ Motion Premise’.
