This paper deals with three themes from David Hume and discusses their consequences for contemporary meta-ethics: The Slavery of Reason Thesis; The Motivation Argument; Hume’s No-Ought-From-Is thesis.
This is a paper straddling metaethics (the nature and justification of moral judgements), the history of philosophy and the philosophy of logic. It deals with three themes from the work of David Hume (1711-1776) together with "matters arising" from the Humean agenda:
- The Slavery of Reason Thesis ("reason is and ought only to be the slave of the passions"). What does this mean? Is the Slavery of Reason Thesis (or something like it) correct? And what (if anything) does this suggest about the nature of ethics?
- The Motivation (or Influence) Argument:
- Morals have an influence on the actions and affections. [Premise]
- Reason alone, as we have already proved, can never have any such influence. [Premise]
- Morals...cannot be derived from reason
- Hume's No-Ought-From-Is thesis: "[It] seems altogether inconceivable", says David Hume, "that this new relation or affirmation [ought] can be a deduction from others, which are entirely different from it". What did Hume mean by this? Can you deduce an ought from an is? If not, why not? And what (if anything) does this suggest about the status of moral judgements? We focus on the idea, common in the 18th century, that logic is conservative - that in a valid inference you cannot get out what you haven't put in. In a famous paper the great New Zealand logician Arthur Prior challenged No-Ought-From-Is, along with the concept of conservativeness. We discuss the responses of Pigden, Schurz, Greg Restall and Gillian Russell, who all try to vindicate different versions of No-Ought-From-Is in the face of Prior's counterexamples.
