Contradiction epistemology in the context of the law of unity and struggle of opposites

The problem of divergence of dialectical materialism from the materialist worldview, which causes the necessity of epistemological and ontological comprehension of the known laws of dialectics, is considered. Since the law of transition of quantitative changes into qualitative ones and the law of negation of negation have been considered by the author in previous works, the subject of the study becomes the law of unity and struggle of opposites. The unity and contradictions of the object of cognition are placed in the focus of the research. The unity of the object of cognition is qualified within the framework of the system approach as its integrity, in turn defined through stability and localization. Consideration of contradictions of the object of cognition revealed their division into real and imaginary. Real contradictions are associated with the processes of creation and destruction, underlying the existence of all objects in the world. Imaginary contradictions arise in the process of cognition and include contradictions of unreliability of knowledge, methodological contradictions and terminological contradictions. Among the imaginary contradictions also includes the contradiction of identity and difference of the object of cognition.
