عنوان مقاله [English]
Since Mullā Ṣadrā in a discussion like the relationship between the constant and the changing insists on constancy of the change, this important problem appears that how much the paradoxical expression of “constancy of the change” is acceptable. The main purpose of the essay is to critically study the very Ṣadrian version of constancy of the change in the constant–changing relation and similar discussions. We will see that Ṣadrian commentators have had different reactions to such expressions as constancy of the change: Some, like ʻAllāmah Ṭabāṭabāyī, have accepted it and some, like Muṭahharī and Miṣbāḥ Yazdī, have not. The criticism of Muṭahharī and Miṣbāḥ Yazdī, shortly speaking, is the claim that constancy of the change is abstract and mental property not external one and that it is conceptual not extensional. We will continue to criticize the evaluations of Muṭahharī and Miṣbāḥ Yazdī: if there is not some kind of constancy in the external world as the truthmaker, our mind cannot apply the concept of constancy about the external changings. Finally, we will focus on the logical structure of the discussion in our special critique of constancy of the change to show that Ṣadrian version of constancy of the change is not merely a paradox but seemingly a real contradiction. But, if, on the contrary of Ṣadrian Philosophy, we consider constancy of the change merely as an external time permanence, there will not emerge the non-material constancy contradictorily from this intensity of the change.
