Rereading of the Reasons for Negation of Quiddity in God from the Islamic Philosophers’ Viewpoint

God’s quiddity is among the most important issues in Islamic philosophy. In discussions of theology in its particular sense, after proving the existence of the Necessary Being, philosophers discuss His affirmative and negative attributes. One of the negative attributes is God’s lack of quiddity, which is closely related to His simplicity. Philosophers believe that unlike possible beings that have quiddity, God has no quiddity (in particular sense), and present arguments for God’s lack of quiddity, among them one can refer to the followings ones: non-existence of action and acceptance simultaneously, essentiality or accidental existence of necessary being, causing the existence of God, accompaniment of quiddity and causation, succession in necessary beings, composition or need in necessary being, essential origination of God, …. The most important of these is the non-existence of composition in God the Exalted, whether the internal composition (simplicity of essence) or external composition (essential unity). In this article, while stating the reasons for negation of quiddity in particular sense in God, we investigate the reasons and some objections put forward by the opponents. Finally, we refer to the inability of some arguments in negation of quiddity in God to conclude that some arguments for negating quiddity in God are ultimate and perfect, and one may resort to them.
