Processes of empiricizing folklore and political science as well as enlarging and anthropologizing the culture concepts of both sciences are the subjects of this essay. According to a long-standing tradition of thought, cultural science and political science are defined as products of modern knowledge systems (as referring to Weber and Durckheim). Still, and much in the same way as cultural policy, it increasingly engages in the communication between culture and societal systems. Practical orientation is a characteristics of empirical cultural science, thus distinguishing it from political science that devotes itself to analytical pure research. Due to that practical orientation, cultural science (and, similarly, cultural policy) gets involved in current political debates and, in part, in popular trends.
