The fundamental unit of assessment in the sociobiology debate is neither a field nor a theory, but a framework of group commitments. Recourse to the framework concept is motivated, in general, by post-Kuhnian philosophy of scientific change and, in particular, by the dispute between E. O. Wilson and R. C. Lewontin. The framework concept is explicated in terms of commitments about problems, domain, disciplinary relations, exemplars, and performance evaluations. One upshot is that debate over such charges as genetic determinism, reductionism, (...) adaptationism, and the biologization of human nature has been vexed. It has lost sight of human sociobiology's central problem, namely to help show that the modern synthesis is complete. (shrink)

The purpose of this essay is to investigate the properties of singular causal systems and their population manifestations, with special concern for the thesis of methodological individualism, which claims that there are no properties of social groups that cannot be adequately explained exclusively by reference to properties of individual members of those groups, i.e., at the level of individuals. Individuals, however, may be viewed as singular causal systems, i.e., as instantiations of (arrangements of) dispositional properties. From this perspective, methodological individualism (...) appears to be an ambiguous thesis: some properties of collections of (independent) systems of the same kind are reducible, but other properties of collections of (dependent) systems of the same kind are not. In cases of the first kind, therefore, methodological individualism is true, but trivial; while in cases of the second kind, it is significant, but false. Hence, if the arguments that follow are correct, at least some of the properties of social groups should qualify as emergent. (shrink)
