Rational choice, on a means-end conception, involves seeking effective means to one’s ends. From this basic idea, the social sciences have developed an instrumental model of rationality. The instrumental model goes beyond a means-end conception by inferring from it not only that rational choice involves seeking effective means to one’s ends but also that rational choice involves nothing beyond this. Ends must be taken as given, as outside the purview of rational choice. All chains of justification eventually terminate in something unjustified. This essay is for those who want to go beyond that.
