In any science, obstacles to its progress can have an objective or subjective origin. It may be that the object studied by science is distinguished by such properties that prevent the researcher from coming close to the phenomenon, distinguishing it from other phenomena, etc. The totality of such unfavorable circumstances for science that lie in the subject of study can be called objective obstacles to the development of this science. On the other hand, it may very well be that in the position of the researcher himself, when studying this series of phenomena, there is something unfavorable for the true idea of ​ ​ the phenomena. Such circumstances can be called subjective obstacles to the development of science.
