Content skepticism about practical reason is doubt about the bearing of rational considerations on the activities of deliberation and choice. Motivational skepticism is doubt about the scope of reason as a motive. Some people think that motivational considerations alone provide grounds for skepticism about the project of founding ethics on practical reason. I will argue, against this view, that motivational skepticism must always be based on content skepticism. I will not address the question of whether or not content skepticism is (...) justified. I want only to establish the fact that motivational skepticism has no independent force. (shrink)
