The main questions addressed in the present article are: How the divine knowledge of the essence and the creatures is perceived by Avicenna and Mulla Sadra? What are possible similarities and differences in the viewpoints of the two philosophers? And which view is more complete and less defective? According to the findings of the study, Avicenna and Mulla Sadra interpret God's knowledge of the essence through the union of the knower and the known, but the divine knowledge of the creatures is addressed by Avicenna through the imprinted forms while Mulla Sadra deals with the issue through the principality of existence and its degrees of gradation. It was also shown that the explanation of Avicenna about God's knowledge of the creatures faces problems such as the emptiness of the God’s essence from the cognitive perfection. But Mulla Sadra's explanation can account for this issue more effectively.
