 Popper’s hostility to psychologistic approaches to epistemology is evident from his earliest works. Questions relating to the origins of convictions, feelings of certainty and the like, he argues, are properly considered the province of psychology; their attempted use in epistemology, which has been characteristic in particular of some schools of empiricism, can lead only to confusion and ultimately to scepticism. Against it, he repeatedly insists on the objectivity of scientific knowledge and sees it as the principal task of epistemology to engage with the questions of justification and validity in that connection (2002: 7).
