Although Karl Popper's falsificationism has been widely criticized by philosophers,[19] Popper has been the only philosopher of science often praised by many scientists.[12] Verificationists, in contrast, have been likened to economists of the 19th century who took circuitous, protracted measures to refuse refutation of their preconceived principles.[20] Still, logical positivists practiced Popper's principles—conjecturing and refuting—until they ran their course, catapulting Popper, initially a contentious misfit, to carry the richest philosophy out of interwar Vienna.[11] And his falsificationism, as did verificationism, poses a criterion, falsifiability, to ensure that empiricism anchors scientific theory.[2] ./cache/en-wikipedia-org-5226.html ./txt/en-wikipedia-org-5226.txt
