Professor Khosrupanah believes that we need Islamic humanities to create Islamic civilization. He considers the relationship between Islamic civilization and Western civilization as a "choice" and seeks help from religion to refine the anti-religious metaphysics of existing sciences and turns to Sadra'i philosophy to provide the philosophical metaphysics of sciences and finally, after pathologizing Islamic philosophy with the innovative method of "observation" (historical-logical), he discovers "self-wisdom". In the founding philosophy of Professor Khosrupanah, each of the concrete or abstract and inferred complications and rulings of the concrete existence of man becomes a big issue, whose complications and rulings give birth to philosophies that add to the facts. He revises the philosophies of sciences and the sciences themselves with the method of observation, and applies the generated metaphysics first to the philosophy of each science and then to the sciences themselves, so that religious science is obtained. But the result of such a scientific and philosophical thought will be, not a civilization based on the revelation and teachings of the prophets. Other criticisms have also been raised about this theory of Professor Khosrupanah, including "its basis on the assumption of the capacity of Sadra's philosophical system to enter the arena of science management and discussion of the philosophies of truths". In this article, after stating the necessity of searching for religious science, we will discuss the two fields of "what is modern science" and "what is religion" in order to get closer to the understanding of the theory of religious science of this expert.
