This is a review essay about Russ Shafer-Landau's Moral Realism. In Moral Realism, Russ Shafer-Landau divides cognitivist moral theories between realist and constructivist versions, where constructivists characterize morality as necessarily connected to the responses of agents under some conditions. This division is misleading; some constructivist or response-invoking characterizations of ethics are fully realist. We need not deny that reasons must be able to motivate rational agents in order to vindicate realism. Rationalists such as Shafer-Landau are committed to the truth of response invoking necessary biconditionals connecting morality and reasons. Furthermore, reasons must be capable of governing the choices of rational agents. Thus moral judgements must be capable of motivating agents.

Robust moral rationalism has long been regarded as incompatible with the Humean Theory of Motivation which requires desires to ground motives. Recently this orthodoxy has been challenged on the ground that rationality itself might require certain desires. This strategy does not remove the tension between rationalism and the Humean Theory. If rationalism is correct, new normative beliefs should engender new motives - motives not grounded in a means-ends fashion in rationally required existing desires. Thus the motivational responses we should expect would be ruled out by the Humean Theory, even when supplemented by rationally required desires. Anti-Humeans about rationality should not be Humeans about motivation.

Most contemporary moral philosophy is concerned with issues of rationality, universality, impartiality, and principle. By contrast Laurence Blum is concerned with the psychology of moral agency. The essays in this collection examine the moral import of emotion, motivation, judgment, perception, and group identifications, and explore how all these psychic capacities contribute to a morally good life. Blum takes up the challenge of Iris Murdoch to articulate a vision of moral excellence that provides a worthy aspiration for human beings. Drawing on accounts of non-Jewish rescuers of Jews during the Holocaust Blum argues that impartial principle can mislead us about the variety of forms of moral excellence.

Expressivist analyses of evaluative discourse characterize unembedded moral claims as functioning primarily to express noncognitive attitudes. The most thorny problem for this project has been explaining the logical relations between such evaluative judgements and other judgements expressed using evaluative terms in unasserted contexts, such as when moral judgements are embedded in conditionals. One strategy for solving the problem derives logical relations among moral judgements from relations of "consistency" and "inconsistency" which hold between the attitudes they express. This approach has been accused of conflating inconsistency with mere pragmatic incoherence. In reaction such criticisms several recent theorists have attempted to use alternative resources. The most sophisticated noncognitivists have often propounded theories with secondary descriptive components in addition to their primary expressive meanings. Recent independent suggestions by Frank Jackson and Stephen Barker attempt to solve the embedding problem by utilizing such descriptive components of moral utterances. Unfortunately, this strategy fails to handle a certain sort of example using just the descriptive resources available to noncognitivists. For it must rule valid arguments invalid in virtue of equivocation in the secondary descriptive meanings. The present paper explains the problem and suggests a moral for expressivist theories.
