عنوان مقاله [English]
In the book The Principles of Philosophy and the Method of Realism, Tabataba'i investigate the Newton's First Law from a philosophical point of view. Also, in the book of Nahayat al-Hikmah, he has focused on the issue of energy and the law of the conservation of matter and energy. Motahari has also addressed these two physical problems in his works and studied them from philosophical point of view. Since it seems that the Newton's first law contradicts this philosophical principle, which every movement required an initiator, these two contemporary philosophers have tried to answer these problem and interpret them consistently with the philosophical rules. They also, by designing the energy issue and studying the law on the conservation of matter and energy, have attempted to determine the place of energy among Aristotle categories. The conversion of matter and energy also raises this question of whether the substance, when converted to energy, abandons its face, and in contradiction with this philosophical rule, which the substance never separates from the face? In this article, the philosophical attitude of Allameh Tabataba'i and Motahari regarding these two physical laws has been examined.
