Abstract

In this paper I expose the hermeneutic turn in Popperian philosophy of science. It is a milestone in the search of scientific rationality because permit us explain and understand both the method of deductive test of theories and the growth of knowledge. Especially, incorporating hermeneutics parameters, build up from Popper’s point of view, like situational logic, supported on the third world theory and the scientific tradition theory, open a door to another form of understand the scientific rationality. It expands the ingenuous model of falsification towards the question of increase of knowledge, which consists on pose problems, putforwards tentative theories, evaluate error elimination, and generate new problems. One of the outcomes leads us to replant our conception of Popper’s philosophy of science close from an hermeneutic point of view.
