Evidence on the Presence of the Principiality of Existence in Ibn Sina s Thoughts in the Viewpoint of the Transcendent Philosophy

The principiality of existence is the basis of the Transcendent Philosophy. Mulla Sadra has demonstrated this principle based on solid arguments and used it as the foundation of his other philosophical principles. Although this issue was not raised in the time of Ibn Sina, one could ask if it could be traced in his words. Another related question here is whether any sound evidence demonstrating the existence of this principle could be found in Ibn Sina’s thoughts so that there would remain no excuse for interpreting his philosophy based on the principiality of quiddity. This study is intended to provide a number of strong proofs in favor of the considerable influence of the principiality of existence on Sinan philosophy through resorting to the statements made by Mulla Sadra and Ibn Sina. In order to confirm his intended principiality of existence, Mulla Sadra refers to Ibn Sina’s words. In fact, many of his views reveal his belief in the principiality of existence, and there are some direct references to this point in his works. Here, the author will try to present and explain the proofs testifying to the truth of this claim within the borderlines of the conducted study.
