For centuries, philosophers have been puzzled by the fact that people often respect moral obligations as a matter of principle, setting aside considerations of self-interest. In more recent years, social scientists have been puzzled by the more general phenomenon of rule-following, the fact that people often abide by social norms even when doing so produces undesirable consequences. Experimental game theorists have demonstrated conclusively that the old-fashioned picture of "economic man," constantly reoptimizing in order to maximize utility in all circumstances, cannot provide adequate foundations for a general theory of rational action. The dominant response, however, has been a slide toward irrationalism. If people are ignoring the consequences of their actions, it is claimed, it must be because they are making some sort of a mistake.

In Following the Rules, Joseph Heath attempts to reverse this trend, by showing how rule-following can be understood as an essential element of rational action. The first step involves showing how rational choice theory can be modified to incorporate deontic constraint as a feature of rational deliberation. The second involves disarming the suspicion that there is something mysterious or irrational about the psychological states underlying rule-following. According to Heath, human rationality is a by-product of the so-called "language upgrade" that we receive as a consequence of the development of specific social practices. As a result, certain constitutive features of our social environment-such as the rule-governed structure of social life-migrate inwards, and become constitutive features of our psychological faculties. This in turn explains why there is an indissoluble bond between practical rationality and deontic constraint.
