This paper puts forward mainly F. Bonsack's and Gonseth's conception of epistemological realism. In their opinion theory is characterized by schematic correspondence with the reality. It regards actually lasting controversy between the realists and unrealists and conditions of cognitive world view. The cognitive objectivism may increase through exploring and elimination subjective's determinants. It considers the criterion of physics reality object of cognition which was set up by F. Bonsack. This criterion is connected with invariable cognitive contents. In this article it shows this criterion and its hypothetic character.
