The article proposes a hypothesis that despite of the ideological opposition of the scientist and hermeneutic methodology of social science and human studies, these two theoretical approaches, in spite of their ideological irreconcilability are methodologically interconnected. These paradigms interact in cognition according to the principle of complementarity and thus compensate mutual constructive disadvantages on the macro- theoretical level. The dualism on macro-theoretical level explains both the methodological rigidity of the structure of dominating positivist language of sciences and the anti- scientist methodology of hermeneutics, which attempts to fill the gaps in cognition created by scientism. Thus, any social fact is dual and can be approached from both positions. Together hermeneutics and scientism generate meta-paradigmatic unity and form the basic methodological opposition inside the social knowledge.
Keywords: truth, cognition, paradigm, hermeneutics, scientism, dualism, methodology, complementarity.
