The position of True Existence in the thoughts of Plato and Mullah Sadra

Plato in his philosophy school offers a special system for universe based on relationship between shadow or photograph and the true being. In this way, he talks about a transcendental being that is the origin of Good (God in his philosophical system) and is beyond existence. By paying attention to position of the origin of the Good in the universe and analyzing the quality of "benefitting" it becomes clear that true existence is confined to it and the other beings are only reflections and shadows of it so that we cannot consider any independence for other beings even "the ideas" and therefore, Plato's ontology circles around a single truth. Mullah Sadra also by offering his final theory "personal pantheism" confines beings to one single being (God) and considers the other beings as His manifestations, since multiplicity of the appearances does not contradict unity of the truth. The present paper tries to discover the similarities and differences of Plato and Mullah Sadra's approach to the true existence based on their different anthological ideas.
