Postpositivism. Science is the servant of power. Conventionalism
This term is commonly used to designate the works of several philosophers of the mid-20th century, thematically united around questions of scientific methodology and subjecting the concepts of classical rationality to rethinking. Among the most famous representatives of postpositivism are K. Popper, T. Kuhn, I. Lakatos, P. Feyerabend, M. Polanyi, K. Hübner. In fact, M. Foucault is not far from this movement of thought. Late postpositivism gave rise to the sociology of science.
