SOME THINK THAT MORAL REALISTS CANNOT RECOGNIZE THE PRACTICAL OR ACTION-GUIDING CHARACTER OF MORALITY AND SO REJECT MORAL REALISM. THIS FORM OF ANTI-REALISM DEPENDS UPON AN INTERNALIST MORAL PSYCHOLOGY. BUT AN EXTERNALIST MORAL PSYCHOLOGY IS MORE PLAUSIBLE AND ALLOWS THE REALIST A SENSIBLE EXPLANATION OF THE ACTION-GUIDING CHARACTER OF MORALITY. CONSIDERATION OF THE PRACTICAL CHARACTER OF MORALITY, THEREFORE, DOES NOT UNDERMINE AND, INDEED, SUPPORTS MORAL REALISM.

Believers in the objectivity of morals are required some time or another to reply to their opponents’ objections, to supply an acceptable account of the evidence deployed by their opponents consistent with their own view, and to bring to light reasons for rejecting their opponents’ case. This paper is intended to go some of the way towards carrying out these objectives. Moral objectivists must also, of course, furnish a positive and defensible account of the status of moral judgments; and, as (...) Kai Nielsen has suggested, they should also ideally construct an acceptable theory of normative ethics, if only to put flesh on the skeleton of their metaethical analysis: though this latter task is not an obligatory one, for their metaethical claims will entail that there are true moral judgments, but need not settle which these are or even how to decide which these are. The present paper contains no more than hints on how in my view these further projects may be accomplished. (shrink)

My thesis is that morality arises when a group of people reach an implicit agreement or come to a tacit understanding about their relations with one another. Part of what I mean by this is that moral judgments - or, rather, an important class of them - make sense only in relation to and with reference to one or another such agreement or understanding. This is vague, and I shall try to make it more precise in what follows. But it (...) should be clear that I intend to argue for a version of what has been called moral relativism. (shrink)
