Additionally, some theorists embrace global versions of fallibilism (claiming that no human beliefs have truth-guaranteeing justification), while others restrict fallibilism to particular areas of human inquiry, such as empirical science or morality.[7] The claim that all scientific claims are provisional and open to revision in the light of new evidence is widely taken for granted in the natural sciences.[8] Another proponent of fallibilism is Karl Popper, who builds his theory of knowledge, critical rationalism, on falsifiability. ./cache/en-wikipedia-org-6913.html ./txt/en-wikipedia-org-6913.txt
