Hume on Practical Reason: Against the Normative Authority of Reason
Abstract
In broad outlines, the first of these claims that beliefs and other cognitive states, on their own, can never motivate a new desire, intention, or action. Rather, on this view, what motivates us to desire, intend, or act is always the cooperation of some desire (or other conative state) with such cognitive states. Thus, on HTM, practical motivation is always the product of two fundamentally distinct categories of mental states operating in conjunction with one another.
