As I completed that manuscript, it became clear that the sciences of human behavior I was using to exemplify scientifi c plurality required far more space than I could allot to them. My observations needed to be articulated in the context of more pressing questions raised by the very aim of understanding human behavior. At the time those included the conceptualization of behavior and the complicated relationships among the sciences, culture, and policy. Th ese matt ers demanded treatment on their own merits. As I have worked my way through this investigation, I have used a social epis- temological methodology to understand the diff erences and similarities among the several approaches, focused on characterizing what the diff erent approaches are dedicated to explaining, and followed the circulation of assumptions and val- ues through multiple technical and cultural contexts. Th e sciences of behavior have recently been advanced by rapid changes in genetics and neurobiology, as well as in the psychological and social sciences. Nevertheless, the persistence of certain themes across the decades invites philosophical inquiry into the kind of knowledge these sciences provide about human behavior and how it matt ers. • I’ve been fortunate in being given opportunities to present parts of this work at national and international conferences and universities.
