 Proponents of both the broader and the narrower accounts of reasoning should agree, however, that there are rational constraints on intentions. The akratic agent, for instance, is a paradigm of irrationality, and this means that there is some kind of requirement to intend to do what one believes one ought to do (just as there are rational norms that are violated when one is afraid of something that one knows to pose no real danger at all). Our capacity for practical reason must involve some capacity to modify our intentions in accordance with this requirement, otherwise practical reason will be practical only in its subject matter, but not in its issue.
