A Critique Of Ibn-sina And Mulla Sadra's Ideas Of The Four-fold Accidental Motions
Abstract
In this Paper, the Writer has analyzed the ideas of these two great philosophers of motion in the four accidental categories of 'quantity, quality, place, and position, and derived the following conclusions:- Mulla Sadra's definition of motion is more convincing than that of Ibn-Sina.- The reason given by these two philosophers for preferring one of the possibilities concerning the meaning of motion in the category of existence is not error-free.- None of the referents proposed for quantitative motion have thenecessary characteristics for being such in reality.- The most certain referent for qualitative motion is motion in essential qualities.- The reason adduced for proving rotational motion is not error - free.- Although motion in place is certain, there is some doubt concerning whether place and position are categories in the real sense of the word.
