In The moral problem (1994), Michael Smith tries to link three conflicting theories that alone are intuitively plausible, nevertheless, they do not seem to work well together. The first proposes that moral judgments are in fact beliefs about objective matters. The second states the concept of “practicality requirement”. The third is a humean belief-desire psychology, i.e. if a moral judgment is sufficient to explain actions, then it must involve a desire. If that is the case, it cannot be simply a (...) belief. For Smith, any attempt to solve the moral problem must find a way to hold all three doctrines. I will argue that his solution rests on two false assumptions. The first, a rationalist one which supports that what we have reason to do is what we would desire to do if we were fully rational. The second is the internalist thesis about moral motivation according to which a person who believes she is morally required to do something is either necessarily motivated to do it or she is practically irrational. I will base my critics on four objections raised by Copp, Miller, Shafer-Landau, Brink and Sayre-McCord. (shrink)

Metaethical relativists sometimes use an interesting analogy with relativism in physics to defend their view. In this article I comment on Erler’s discussion of this analogy and take the discussion further into methodological matters that it raises. I argue that Erler misplaces the analogy in the dialectic between relativists and absolutists: the analogy cannot be dismissed by simply pointing to the fact that we have absolutist intuitions – this is exactly the kind of objection the analogy is supposed to be (...) a defence against. To decide if the analogy works we need to answer the following two questions: (i) Why does it work to say that people refer to relative physical properties (like simultaneity, mass and motion) even though they intend to speak about absolute physical properties? And (ii) does the answer carry over to the moral case? I argue for a specific answer to (i), and argue that it gives us reason to answer (ii) in the negative – so the analogy does not hold. However, looking at the issue more closely also raises questions about a fundamental assumption in metaethical discussion: perhaps we cannot assume that one single analysis holds for everyone’s moral judgments.
