 However, many non-cognitivists want to vindicate as much of actual moral thought and practice as possible, particularly quasi-realists such as Simon Blackburn (1993) and Alan Gibbard (2003). While denying that there are, strictly speaking, moral propositions that are true or false (or moral beliefs, or moral arguments that are valid or invalid), they would at the same time maintain that in the moral realm there are things close enough to propositions, truth, belief, and validity that our practice of speaking of such things as moral beliefs and these beliefs being true or false makes sense. And such theorists would certainly want to allow that moral beliefs can be better or worse in a way that closely corresponds to beliefs being more or less epistemically justified, strictly understood. So there are interesting questions about whether there is something closely akin to a priori moral justification (and knowledge) on these views. But in this entry we will limit ourselves to cognitivist theories.
