Abstract

Normative nonrealism denies, first, that some things are good or bad independently of facts about the attitudes of moral agents and, second, that attitude-independent moral facts determine what is rational. This implies that facts about what is rational are logically prior to what is moral. Nonrealism commonly assumes (a) that moral realism is false or unjustifiable, (b) that there is a conceptual connection between morality and rationality and (c) that the particular theory of rationality is the correct account of rationality. Facing the threat of relativism when abandoning (c) it is argued that (c) is at least dubious. Semantic considerations concerning the meaning of "rationality" are sketched and the full-information approach of decision making, intemalism and extemalism are discussed in the light of "Why care?"-questions with the resuh that these questions do serious damage to nonrealist approaches to rationality and reason-based morality.
