Philosophical ideas have always been shaped and evolved within specific historical and cultural contexts. The history of philosophy testifies that Muslim philosophers, especially Mulla Sadra, were not merely inheritors of Greek philosophical traditions, but through a creative reinterpretation and reconstruction of these traditions in light of Islamic philosophical and theological heritage, they produced novel ideas. Mulla Sadra considers wisdom to be exclusive to sciences that originate from the religion of the Divine Prophets and refers to certain Greek philosophers (the Eight Wise Men) who, through asceticism and piety, transcended the sensible world and adopted the ethics of the Divine. They reached ultimate truth and, regarding the issue of the origination (huduth) and eternality (qadim) of the world, are in harmony with the Prophets. In his works, Mulla Sadra, with reference to the history of Greek philosophy and particularly relying on Plato’s teachings, examined topics such as the theory of forms, substantial motion, and the origination and eternality of the world. This study, employing a combination of historical, comparative, phenomenological, and analytical methods, seeks to explore the reflection of Greek ideas- especially those of Plato- in Mulla Sadra’s works. To this end, it analyzes Mulla Sadra’s writings and the doctrinal commonalities between him and Plato in the realms of ontology and epistemology, aiming to clarify the influence of Plato on Mulla Sadra’s philosophical system.
