Analytical Study of traversal and cutting movement in the View of Ibn Sina and Mulla Sadra

Ibn Sina's and Mulla Sadra's use of traversal & cutting movement led to ambiguity in the movement existance. In this research, in order to eliminate this ambiguity, we have addressed the following: One, Ibn Sina's arguments for introducing two definite meanings of motion, which are the responses to the bugs inflicted on the existence of motion and the reason for the very nature of motion; His arrangements have been explained in that they are the separation of the first perfection from the second, as well as the separation of the connection from the movement. After answering the problems raised by Ibn Sina's point of view it is clear that Mulla Sadra has succeeded in completing Ibn Sina's method by bringing forward the discussion of the Transcendent Philosophy, but Mulla Sadra has not explicitly proved the existence of a definite existence by justifying it on the basis of the principiality of existence
