Mulla Sadra s of Substantial Motion

One of the most important philosophical theories of Mulla Sadra is substantial motion, which has greatly influenced other philosophical discussions. In this article, first we refer to the historical background of the theory before Mulla Sadra, namely in Peripatetic Philosophy, and then deal with Mulla Sadraʹs innovations, such as transferring the discussion of motion from natural philosophy to metaphysics, explaining clearly substantial motion, stating the five important arguments for the theory, and finally showing its main philosophical results like the explanation of Godʹs creation, the reality of time, origination of the material world, the relation of the originated to preeternal being, the unity of the world, and proving Godʹs existence and the Resurrection.
