Muhammad ibn Ahmad (Mohaghegh) Khafri's Views on the Principality of Existence

The well-known idea spread in philosophical assemblies is that transcendental philosophy has a large role on topic of existence, especially, on the principality of existence. The present essay aims at addressing the question whether the Principality of Existence has its roots in doctrines proposed by philosophers before Mulla Sadra or not? If yes, then what is their contribution to the subject?
Proposing eight arguments (drawn on Khfri’s views (9th-10th centuries H), including the impossibility of changing the state of possibility of quiddity without existence, the actualization of common technical predictions, the impossibility of concepts without tokens, the impossibility of deducing the concept of existence from quiddity, the impossibility of correspondence of the commonality of existence concept with quiddity, the existential gradation, the origin of quiddity being predicated by existence, and the cause of actualization of particular things, we come to the conclusion that he had arguably introduced the subject of Principality of existence in his works a long time before Mulla Sadra.
