Ontological Evaluation of the Theory of Eexplaining Plurality in Mulla Sadra's Unificationist System

Mulla Sadra has based his philosophical system on a number of principles, which will have important implications for each of them; the most important of which is the "Originality of Being", whose belief will lead to the adoption of the well-known theory of "unity of existence"; A view that is based on the denial of the full difference. On the other hand, the basis of "Hierarchy of existence" is one of the pillars of Mulla Sadra's philosophy, which plays a major role in explaining the plural theory of the beings of the universe. Sadra has attempted to explain two of the aforementioned foundations that do not fall into the paradox of the unity and plurality; what has made him successful for the first time in providing a rational explanation of the theory of “Multiplicity While Unity” is his particular reading of the theory of unity of existence using the viewpoint of Hierarchy of existence that is formed in the context of the two bases of the Originality of Being and the existence of a disabled interface.
