The article deals with the theoretical problems of the historical scholarship which has a crisis of epistemological foundations to share with other social sciences. The multiplicity of the description languages is so potentially vast that historians are impeded to find a theoretical basis for their research. Most often they are satisfied with the language of "natural reasoning", traditional for the social sciences and everyday life, and their methodological choice is justified by only mentioning prominent theorists of humanitarian knowledge. At the same time, most of the theoretical reasoning about history are devoted to criticizing its narrative nature and are not aimed at finding unifying criteria that could strengthen the scientific validity of academic studies treating the past. Thus, modern historiographical and philosophical reflection on the theoretical foundations of history exists in the form of disjointed and contradictory manifestations. It does not offer ready-made recipes on the basis of which an "epistemological consensus" could emerge. For all that, the tendency of the last few years reflects the notable drift of social theory towards the search for some kind of "integral paradigm", localized within the framework of the "new ontological turn". The basis of this reasoning is the recognition of the objective and independent (intransitive) nature of the social world, which exists despite any intercurrent (transitive) interpretations created by researchers. Supporters of this ideological mainstream suggest the conceptualization of ontology and the implementation, with a view to research, of most (if not all) of the diverse experience approved itself in social sciences, advocating for the broad utility of the "methodological bracketing" technology designed back by A. Giddens in his theory of structuration. The focus of the research here is constructed in such a way as to pre-create a hybrid ontological conceptualization, "putting in brackets" categories and internal, peculiar to the research, that are best according to the object under study. The researcher can create in such a manner hybrid mixtures of abstract and distinctive ontological concepts that come from various scientific traditions that were identified as most relevant to the fragment of reality under consideration, practicing a "widely informed" realism. The humanities already have extensive experience in the classification and practical application of methodological bracketing, the technology of which, as far as we know, has not been applied in the historical research. The prolific development of this initiative will be the creation of interdisciplinary collaborations, within which historians, with the assistance of related research spheres partners could enter the path of methodological search, combined with their traditional research practices.
