Abstract

Preference-based theories of prudential value seem to generate an absurd result when combined with commonplace platitudes about prudential rationality: it would seem that if the satisfaction of our preferences is the source (or even a source) of prudential value, then prudential rationality must be neutral (in, at least, a troubling range of cases) between taking steps to achieve the objects of one's preferences and merely engineering one's preferences to take as their object(s) that which obtains. Either way, one seems to conform to the prudential demand to promote one's well-being. But this is widely held to be counterintuitive. In this article, I argue that this verdict arises only given eminently controvertible interpretations of a preference-based axiology and of the constitution of prudential reasons.
