Abstract

Mulla Sadra has referred to his specific argument concerning the demonstration of the Oneness of Almighty Necessary as the celestial argument. He has also emphasized its superiority to the other arguments propounded by early philosophers, such as Ibn Sina, in this regard. While scrutinizing them to a great extent, he does not consider any of them as a perfect argument free from any kind of defect. He believes that if we wish to view them as perfect arguments, we should try to remove their defects. Therefore, he suggests certain reasons in order to improve and complete them and argues that even Ibn Sina's argument needs some correction. In this paper, the writer has tried his best in order to show that, unlike the arguments of other philosophers, that of Ibn Sina, along with its various interpretations, is needless of Mulla Sadra's correction and modification. In fact, he intends to demonstrate that Ibn Sina's argument enjoys the necessary efficiency for demonstrating the Oneness of Almighty Necessary.
