Abstract

In The Poverty of Historicism, Karl Popper attacked a number of anti?naturalistic doctrines while advocating a program of piecemeal social reform. However, recent work in social science, and especially in the evaluation of social programs and social reforms, has exposed difficulties that have led many scientists to fall back on one or other of these same anti?naturalistic positions. It is suggested that Popper's strategy for dealing with anti?naturalism is no longer efficacious, although the difficulties in contemporary social science do not warrant the abandonment of naturalism
