  The fact that moral realists are cognitivists enables them to construe moral disagreements as conflicts of belief, but some cognitivists may also, just like non-cognitivists, need a conception which is different from the realist one. Moral realism is associated with the absolutist view that the truth conditions or contents of moral sentences and moral convictions remain constant across speakers. For example, the realist Richard Boyd insists that there is “a single objective property which we’re all talking about when we use the term ‘good’ in moral contexts” (1988, 312). However, there are also cognitivists who are relativists and think that the truth conditions of moral sentences vary, depending for example on the cultural or social groups which the speakers or believers belong to (see, e.g., Harman 1978 and Wong 1984).
