‘Folk psychology’ designates our commonsense knowledge about the mental causes of the behavior of agents who are rational in much the way that we ourselves are. We use this knowledge to predict and (especially) to explain the behavior of both ourselves and others by attributing beliefs and desires to such agents. Jane went to the refrigerator because she wanted a golden throat charmer and believed that the refrigerator was a conveniently close repository for such a drink. Peter doesn't drive when it snows because he thinks that under those conditions the roads are dangerous, and he wants to avoid harm both to himself and to others. In this chapter I focus on the place that folk psychology has in explaining human behavior, with three questions signifying the parameters of my discussion.

THREE QUESTIONS

First, how is folk psychology related to computationalism in psychology? Part of the motivation for discussing this first question comes from an interest in a more general question: What is the relationship between folk psychology and the cognitive sciences? The computational paradigm dominates much contemporary psychology and has served as an impetus for the cognitive sciences more generally. As a guide to the relationship between folk psychology and the cognitive sciences, I focus on the question about computationalism; such a focus has served as a surrogate for discussion of the more general question in much of the philosophical literature.
