Discussion of knowledge and cognition in the Qur'an According to the pillars of knowledge, the following four topics related to it, namely science, scholar, known and teacher, and issues such as conditions, causes, factors, etc. are discussed. In Islamic sciences, especially in Islamic philosophy and mysticism, in topics such as perception, mental existence, abstract existence, soul, etc., issues related to knowledge are dealt with, which have characteristics, conditions and obstacles. Hazrat Allameh Javadi Ameli has a special explanation in this field by mixing philosophy and interpretation and combining Islamic wisdom with the word of revelation. And hi have different opinions about the perception and consistency of it, despite its existential view of it in different levels of existence and the order of its effects in this field. Allameh Javadi Amoli's approach to issues related to perception is completely based on and in accordance with her interpretive theories of Quranic verses. According to the verses that express the abstraction of the soul, they prove the abstraction of science and, as they consider the abstract matter doubtful, they prove the skepticism in perception. In this way, they raise issues such as the levels of perception and types of perception and how perception is realized. In this article, after the semantics of perception and its ontology, what is perception and then the factors and conditions affecting the realization of perception among the philosophical and interpretive views of Allameh Javadi Amoli are discussed.
