Analysis and Explanation of External Realization of Quiddity

There are two main interpretations of the “fundamental reality of existence”. Some philosophers take the view that the real world is loaded with existence, but as quiddity is nothing more than the instantiation of existence, the two are identical. In contrast, there are other philosophers who argue that the world of reality is loaded by existence and quiddity is just an image of existence in the mind of human beings. According to the first theory, the unity of existence and quiddity is not but the real identity of the two. On the other hand, according to the second theory, the unity of these two means just the application of the concept of quiddity on reality. Although some statements of Sadrolmotalehin are in accord with the second theory, a comprehensive look on his philosophical principles and propositions leads us to the first theory. There are two significant types of evidence which confirm the claim: (1) similarity of the relationship which can be found between existence and quiddity with the relationship which exists between essence and qualities of the divine essence, and (2) Sadrolmalehin’s claim in his discussion of “mental existence” about the coincidence of mental quiddity with the quiddity which exists in the real world.
