The Role of Celestial Factors in Knowledge Based on Estimative Faculty from Molla Sadra's Perspective

Non epistemic agents which influence human knowledge have been discussed by thinkers and philosophers among the history of rational thoughts in west and east. Nowadays this problem is alive and posed by many. This Idea is based on the assumption that existence of knowledge is not confined on humans will alone but follows many factors one of which is immaterial and celestial realities. Moslem philosophers such as Mollasadra, Ibn Sina and Sohravardi, believe that not only the human knowledge but all the errors originate in immaterials too. According to MollaSadra, some agents above which is Satan, thorough a certain process, affect the estimative faculty of human being. This paper shows analytically and descriptively the very process in Sadras view and emphasizes Satans impression (non-physical existence) on human soul which leads to errors.
