Cohon, Rachel. Hume’s Moral Philosophy
Introduction: Hume’s position in ethics, which is based on his empiricist theory of the mind, is best known for asserting four theses: (1) Reason alone cannot be a motive to the will, but rather is the “slave of the passions” (see Section 3) (2) Moral distinctions are not derived from reason (see Section 4). (3) Moral distinctions are derived from the moral sentiments: feelings of approval (esteem, praise) and disapproval (blame) felt by spectators who contemplate a character trait or action (see Section 7). (4) While some virtues and vices are natural (see Section 13), others, including justice, are artificial (see Section 9). There is heated debate about what Hume intends by each of these theses and how he argues for them. He articulates and defends them within the broader context of his metaethics and his ethic of virtue and vice.
Hume’s main ethical writings are Book 3 of his Treatise of Human Nature, “Of Morals” (which builds on Book 2, “Of the Passions”), his Enquiry concerning the Principles of Morals, and some of his Essays. In part the moral Enquiry simply recasts central ideas from the moral part of the Treatise in a more accessible style; but there are important differences. The ethical positions and arguments of the Treatise are set out below, noting where the moral Enquiry agrees; differences between the Enquiry and the Treatise are discussed afterwards.
Tiberius, Valerie. Humean Heroism: Value Commitments and the Source of Normativity
Abstract: This paper addresses the question “In virtue of what do practical reasons have normative force or justificatory power?” There seems to be good reason to doubt that desires are the source of normativity. However, I argue that the reasons to be suspicious of desire-based accounts of normativity can be overcome by a sufficiently sophisticated account. The position I defend in this paper is one according to which desires, or more generally, proattitudes, do constitute values and provide rational justifications of actions when they are organized in the right way.
Comment: A good defence of desire-based accounts of value, tackling some of the most intuitive objections (such as being "too subjective" and having no foundation in reason).
