A Comparative Study of the Transmission from Plurality to Oneness in Plato and MullaSadra's Ontology

Plato on the basis of his unifier viewpoint offered the theory of Idea and other cosmological related to creation and the chain and arrangement of beings. He also placed the principal of Goodness in the climax of the pyramid of his ontology، and by which tried to refer the plurality of beings to oneness. On the other hand، Mulla Sadra by his philosophical and religious principals and on the basis on his unifier viewpoint offered his first ontological theory (i. e. Tashkiki unity of being) and the ultimate one (i. e. personal unity of being). As a result، he also tried to explain the quality of manifold beings by reference to oneness. Despite the thought differences of the two philosophers in the field which based is based on their philosophical foundations، both return manifold beings to unity، so that they regard manifold beings as shadows of a transcendent unity. Ontology in Plato''s thought corresponds with Mulla Sadra''s first theory (i. e. Tashkiki unity of being).
