The last decades have seen major reformations in the philosophy and
history of science. What has been called 'post-positivist' philosophy of
science has introduced radically new concerns with historical, social,
and valuative components of scientific thought in the natural sciences,
and has raised up the demons of relativism, subjectivism and sociologism
to haunt the once- calm precincts of objectivity and realism. Though
these disturbances intruded upon what had seemed to be the logically
well-ordered domain of the philoso- phy of the natural sciences, they
were no news to the social sciences. There, the messy business of human
action, volition, decision, the considerations of practical purposes and
social values, the role of ideology and the problem of rationality, had
long conspired to defeat logical-reconstructionist programs. The attempt
to tarne the social sciences to the harness of a strict hypothetico-
deductive model of explanation failed. Within the social sciences,
phenome- nological, Marxist, hermeneuticist, action-theoretical
approaches vied in attempting to capture the distinctiveness of human
phenomena. In fact, the philosophy of the natural sciences, even in its
'hard' forms, has itself become infected with the increasing reflection
upon the role of such social-scientific categories, in the attempt to
understand the nature of the scientific enterprise.
