B. F. Skinner is perhaps even more widely known for his views on science than for his experimental work. His comments on the role of theory in science have been labeled “anti-theoretical,” “ultra-empirical”, “non-theoretical,” “radical,” and worse. His position appears to be both extreme and untenable. Scriven [1] has given us a critique of Skinner that goes beyond mere labeling; it is an examination of the assumptions and implications of such a position.
