Abstract

The debate on the possibility of attaining metaphysical knowledge by the method of reasoning began with the ancient Greek philosophers and continues to this day. This article aims to examine how Râzî argues for the possibility of attaining metaphysical knowledge through the method of reasoning. He first argues that existence has two parts, the sensed and the thought, in order to demonstrate that metaphysical knowledge can be obtained through the method of reasoning. Then he tries to prove that existence is not limited to the material. After presenting evidence for the existence of things other than the sensible in existence that can be perceived with the intellect, he tries to discuss our devices to relate to this sphere of existence in a comparative manner. In this comparison, two possible devices for attaining metaphysical knowledge emerge: the theoretical intellect and the purified soul. After revealing the positive and negative aspects of both in this comparison, he argues that the most reliable device is the theoretical intellect and the technique is the method of reasoning Râzî gives various answers to those who object to the possibility of obtaining metaphysical knowledge through the method of reasoning. Râzî tries to put forward the grounds on which the groups who object to the method of reasoning are based. He then evaluates their justifications in terms of accuracy and consistency. Thus, he tests both the relevance of each group's objection to the subject and its consistency with the group's other beliefs. He then presents the justifications for his own opinion on the method of reasoning and the consistency of this method with his other beliefs. Following this method, Râzî first divides those who object to the method of reasoning into two categories according to whether or not they accept a metaphysical sphere of existence. According to this division, those who object to the method because they do not accept a metaphysical sphere of existence are the Sophists, Sumeniyya, Mujasimah, Dhahriyya, and Hashawiyya. Although this group does not accept a metaphysical sphere of existence, they are divided into two classes: those who believe in God and those who do not. According to Râzî, the group that accepts the metaphysical sphere of existence but objects to the method of reasoning is the Talimiyya. They claim that metaphysical knowledge can only be attained through the teaching of an innocent instructor, not by the method of reasoning. The different approaches of these groups are the reason why Râzî sometimes emphasizes accuracy, sometimes consistency, and sometimes proving the metaphysical domain of existence in his answers to those who object to the method of reasoning.
