On a standard interpretation, Hume argued that reason is not practical, because its operations are limited to “demonstration” and “probability.” But recent critics claim that by limiting reason’s operations to only these two, his argument begs the question. Despite this, a better argument for motivational skepticism can be found in Hume’s text, one that emphasizes reason’s inability to generate motive force against contrary desires or passions. Nothing can oppose an impulse but a contrary impulse, Hume believed, and reason cannot generate (...) an impulse. This better argument is here developed and defended. Two lines of objection to it can be anticipated: that reason actually can generate impulsive force, based on contents of its normative judgments and that reason neither can nor needs to generate an impulse, since the actions of rational agents are not determined by forceful impulses of desire, as Hume supposed. These objections are answered by pointing out their unsatisfying consequences. (shrink)

This paper considers and argues against old and recent readings of Hume according to which his account of moral judgement is non-cognitivist. In previous discussions of this topic, crucial metaethical distinctions-between sentimentalism and non-cognitivism and between psychological and semantic non-cognitivism-are often blurred. The paper aims to remedy this and argues that making the appropriate metaethical distinctions undermines alleged support for non-cognitivist interpretations of Hume. The paper focuses in particular on Hume's so-called 'motivation argument' and argues that it is a poor (...) basis for non-cognitivist interpretations. While there is textual support for attributing to Hume what may be called 'modally weak' motivational internalism, there is no solid textual support for attributing to him either psychological or semantic non-cognitivism. The paper also challenges briefly some further alleged support for non-cognitivist interpretations. It concludes by offering some positive evidence against such interpretations, namely that Hume appears to hold that there are moral beliefs and moral knowledge. (shrink)
