Abstract

Following Aristotle, Islamic logicians and scientists believe that the subject of science is one of its pillars and maintain that each science has a subject matter and discusses its essential accidents. However, when clarifying the necessity of the existence of subject and determining the nature of its essential accidents and their relationship with the subject, they face great problems. These problems, which are basically rooted in ambiguity and common nomination in the meaning of essential accidents, have resulted in the rise of great disagreements among scholars when trying to bring them in conformity with scientific issues. In this paper, the writer has tried to study and analyze of the essence of the problem and the ideas of various scientists in this regard following a critical approach.
