HOW IS POST-NORMAL SCIENCE POSSIBLE?

The author starts from the contemporary image of "post-normal sci-ence", which implies the openness of science to policy (S. Funtovicz and J. Ravetz). She considers the idea of post-normal science as a normative basis for the scientists' demand for the politicization of science, as a conceptual condition for grasping crises and the role of scientific expertise in their resolution, and as a designation of a spe-cial phenomenon of contemporary science with the ambiguous sta-tus of a scientist-expert. Based on the analysis of the concept, the author emphasizes the problem of combining scientific validity and political relevance, inherent in post-normal science. The ele-ments of this problem are the danger of including science in politics, the violation of objectivity and the lack of demarcating scientific and non-scientific knowledge. The author argues that the solution of the problem becomes possible if the political relevance of science is in-terpreted as interaction, and scientific validity as objectivity are re-vealed through attention to the concept of "knowing-how".
