المعاني المتعددة لانواع الجوهر في فلسفة ارسطو

Substance is one of the principal concepts in the philosophy of Aristotle. In dealing with this problem, we will have considered an important part on which is built most of his philosophy, particularly ontology and epistemology. The paper for this purpose is divided into two sections. The first section looks into the meanings of substance, its essence and qualities. The second section deals with the different types of substance and its meanings in different areas of Aristotle's philosophy. Respectively, these include the metaphysical, the natural and the logical areas. In the metaphysical subsection the paper focuses on the meaning of substance as a self-sufficient abstract concept. In the natural subsection, we have outlined the types of substance and their relation to the mental substance. The logical subsection centers on the importance of substance with regard to the statements, since it is the first existent, not to be found in any subject, while secondary substances are restricted to one subject, which is the substance.
