Abstract:
Might practical reason be a species of theoretical reason? Can we make sense of practical deliberation as a special kind of theoretical cogitation over what you will do? The prospects of such a reduction may appear dim: it seems like it is one thing to be weighing up what you should (intend to) do, in light of your various reasons for action, and quite another thing altogether to be figuring out what you should believe you will do, in light of your evidence.
Here I aim to show how this reduction of our powers of practical reason to a branch of theoretical reason might be defensibly pulled off. On the view to be defended, your intentions to act are really beliefs about what you are will do, practical reasoning is nothing over and above the enterprise of predicting what you are going to do in light of evidence alone, and the constitutive aim of action turns out to be the same as the constitutive object of theoretical reason – namely, to believe the truth.
