The Effect of Believing in Existential Fluidity on Logical Limits in Transcendental Philosophy

One major discussion in Mulla Sadra’s transcendental philosophy is the division of existence into fixed and changeable. Belief in fluid existence is a consequence of substantial motion principle which next to issues like principality of existence, gradation of existence and poverty possibility, has transformed many of philosophical problems of transcendental philosophy.This latter has provided a new notion of body and matter by raising the theory of substantial motion. According to Mulla Sadra, the fluidity of change and movement is the mode of existence of unfixed beings. Here, motion is not an accidental matter but their essence and substance are in motion. By substantial motion and fluid existence, the once fixed picture of the world is shattered. Contrary to pre-sadraian theories in which substances had fixed forms and differentia and logical limit was defined on that basis, in transcendental philosophy, every fluid being has a fluid identity which possesses a series of forms and differentia and therefore logical limits are transformed on this basis. This article first analyzes the forms, differentia and essence of material being in peripatetic philosophy and then deals with the developments of the same notions in transcendental philosophy.
