Abstract

Utilitarianism has frequently been criticized for lacking psychological realism, but what this means and why it is thought to matter varies. This article distinguishes and examines three main relevant kinds of appeals to psychological realism: (a) A minimalist, self-avowedly metaethically neutral and empirically based ‘ought implies can’ approach, exemplified by Owen Flanagan. (b) Arguments from psychological costs and flourishing, exemplified by Michael Stocker and Bernard Williams. (c) ‘Thick’ psychological realism, exemplified by Elizabeth Anscombe, where a conception of human nature does not simply provide constraints on value theory, but forms the substantive basis on which it builds. The main challenge raised for utilitarianism turns out to be metaethical, not a matter of empirical psychology. The question is not so much whether utilitarianism can accommodate (putative) descriptive facts of human psychology as such, but what normative weight these facts should be given and why.

Stocker (‘Schizophrenia’) arguably anticipates a great deal of the debate on indirect consequentialism and utilitarianism in his ‘schizophrenia’ argument – the coming apart of motivation and justification is in his view precisely the problem, and not a solution, to the gap between human nature and what certain moral theories, particularly impartialist ones, ask of agents. I will not try here to settle any of these issues with any definiteness – that would be a topic for a whole different article (at least), but note also that Stocker is arguing primarily against moral theories that imply pervasive disconnect between human motivating drives and moral justification, not against the need for correctives to our actual motivational structures. Stocker's view does however imply that, in principle at least, the reasons a theory provides for action should be suitable to become motives, or the theory is schizophrenic.

Self–other asymmetry as an issue for moral theory is also discussed, with significantly less emphatic conclusions than Stocker's, in Slote, Michael, ‘Morality and Self–Other Asymmetry’, The Journal of Philosophy 81 (1984), pp. 179–92CrossRefGoogle Scholar.

22 A commonly raised possibility, also considered by Stocker (‘Schizophrenia’, ‘Emotional Identification’), is that impartialist ethics that abstract from the ‘thicker’ psychology may be more suited to institutional contexts and decision-making for large populations, while more thickly psychologically realistic approaches might be suited to a level of personal interaction and individual life-choices. But this in turn raises a problem about how cleanly the levels can be kept distinct in practice.
