Abstract

According to the theory of Molla Sadra, primacy of existence constitutes reality. Existence is one but graded in intensity. These two principles namely reality of existence and analogical gradation hold a definite role in the foundation of accepted concept in this paper. Non-acceptance of the two mentioned principles leads one to various results particularly in this case the consequent non-acceptance of substantial movement to understand reality of existence and analogical gradation. One must not fail to compare Molla Sadra’s theory with philosophy of peripatetic. The assumption of this paper claims that substantial movement both in representation and judgment is based on reality of existence and analogical gradation.
