Critical study on Ahsá'í's critics to the substantial motion in the transcendental philosophy

Substantial motion is one the basic foundation of the transcendental philosophy which MullaSadra proves it by the motion of accidents which denote to the transmission of the cause. According to Shaykh Ahmad Ahsá'í because of the God's causality to all creations, substance is not the cause of accident and its motion, in this regard Ahsá'í believes that MullaSadra' theory of substantial motion is a kind of Materialism neglecting God's existence. Ahsá'í believes that all things including stone and wood have free will and on the basis of this, MullaSadra's division of the motion is not correct. In criticizing these critics, it must be said that God's causality to the creations is direct and immediate, because of the need of all creation for the God, MullaSadra' theory does not lead to the Materialism.
