Ignoring a crucial nuance in using the concept of metaphysics is "Does physics come first or metaphysics?" It makes it difficult to answer the question. The nuance under consideration is related to the "two-sided" structure of metaphysics. Metaphysics as a science refers to two types of phenomena with the existence of metaphysical principles - things that cannot be entered into concepts, closed to interpretation, and things that are realized through experience. From this point of view, it can be said that every society, regardless of the level of civilization, has some metaphysical principles. However, it is also observed that societies with metaphysical principles fail to develop metaphysics as a science. To develop metaphysics as a science, it is necessary to engage in natural sciences and use the results of natural sciences. In our research, we will try to show the connection between the areas that feed metaphysical teachings and these areas and metaphysical teachings with examples from the history of philosophy.
