This paper argues against the false dichotomy between reductionism and
holism in the social sciences. I make the points that reductionism is
the mark of a mature science, that the social sciences will never pro
gress until they drop their opposition to reductionism, that higher-le
vel explanations, even when more appropriate and coherent than reducti
onist explanations, must not violate principles established at lower l
evels of explanation, and that reductionist explanations almost always
absorb the explanatory efficiency of broad social categorizations and
add incremental validity to them. I demonstrate the validity of these
points by exploring them in the context of the four most frequently u
sed variables in social science (gender, race, age, and social class).
In each case it is demonstrated that such categories fail to capture
the causes of the phenomena social scientists explore, and that by fai
ling to consider more elemental explanations lead to reliance on hypot
hetical ''social facts'' which are at best incomplete, and are often d
emonstrably wrong. The history of science reveals that all disciplines
at one time or another have resisted the incursions of the more funda
mental sciences, then showed a grudging acceptance of them, and finall
y became fully integrated with them. The social sciences must do the s
ame with regard to integration with the relevant biological sciences.
