  Two observations should be made about this way of understanding practical reason. First, the contrast just drawn might suggest that there is a categorial difference in the consequences of theoretical and practical reason, insofar as the former produces changes in our mental states, whereas the latter gives rise to bodily movements. But it would be misleading to contrast the two kinds of rational capacity in these terms. Practical reasoning gives rise not to bodily movements per se, but to intentional actions, and these are intelligible as such only to the extent they reflect our mental states. It would thus be more accurate to characterize the issue of both theoretical and practical reason as attitudes; the difference is that theoretical reasoning leads to modifications of our beliefs, whereas practical reasoning leads to modifications of our intentions (Harman 1986, Bratman 1987).
