The article compares the philosophical views of Heidegger and Mulla Sadra on ontology, which is the study of existence. Both philosophers explore important questions about human beings, the world, God, movement, time, and the Word of God. Heidegger focuses on understanding human existence through existential analysis, while Mulla Sadra aims to reach objective truth beyond concepts. Their work suggests that understanding the nature of reality involves looking beyond mere ideas.
