Epistemología, ética y política según Karl Popper

this paper looks to examine popper’s view of the critical discussion which, ultimately, is responsible for the creation of daring speculations both in epistemology and in the political and social fields. the author introduces the fallibilist presupposition of our assertions regarding truth. this popperian concern, according to the testability of our hypotheses, moved him to suggest a method which includes the natural and social sciences. for popper, the fundamental principle of unity in science was that the testing of hypotheses in social sciences had to be applied using the same method than in natural science. it is out of these popperian assertions supporting a methodological unity, the principle of fallibility, a sensible discussion and the search for truth-considered by popper both epistemological and ethical principles-that we suggest an analysis of these principles, thus linking epistemology and ethics in popper’s thought.
