When making moral judgments, people are typically guided by a plurality of moral rules. These rules owe their existence to human emotions but are not simply equivalent to those emotions. And people’s moral judgments ought to be guided by a plurality of emotion-based rules. The view just stated combines three positions on moral judgment: [1] moral sentimentalism, which holds that sentiments play an essential role in moral judgment,1 [2] descriptive moral pluralism, which holds that commonsense moral judgment is guided by a plurality of moral rules2, and [3] prescriptive moral pluralism, which holds that moral judgment ought to be guided by a plurality of moral rules. In what follows, we will argue for all three positions. We will not present a comprehensive case for these positions nor address many of the arguments philosophers have developed against them. What we will try to show is that recent psychological work supports sentimentalist pluralism in both its descriptive and prescriptive forms.

What is the significance of empirical work on moral judgement for moral philosophy? Although the more radical conclusions that some writers have attempted to draw from this work are overstated, few areas of moral philosophy can remain unaffected by it. The most important question it raises is in moral epistemology. Given the explanation of our moral experience, how far can we trust it? Responding to this, the view defended here emphasizes the interrelatedness of moral psychology and moral epistemology. On this view, the empirical study of moral judgement does have important implications for moral philosophy. But moral philosophy also has important implications for the empirical study of moral judgement.

The recent, influential Social Intuitionist Model of moral judgment (Haidt, Psychological Review 108, 814-834, 2001) proposes a primary role for fast, automatic and affectively charged moral intuitions in the formation of moral judgments. Haidt's research challenges our normative conception of ourselves as agents capable of grasping and responding to reasons. We argue that there can be no 'real' moral judgments in the absence of a capacity for reflective shaping and endorsement of moral judgments. However, we suggest that the empirical literature indicates a complex interplay between automatic and deliberative mental processes in moral judgment formation, with the latter constraining the expression and influence of moral intuitions. We therefore conclude that the psychological literature supports a normative conception of agency.

Questions regarding the nature of moral judgment loom large in moral philosophy. Perhaps the most basic of these questions asks how, exactly, moral judgments and moral rules are to be defined; what features distinguish them from other sorts of rules and judgments? A related question concerns the extent to which emotion and reason guide moral judgment. Are moral judgments made mainly on the basis of reason, or are they primarily the products of emotion? As an example of the former view, Kant held all moral requirements to be derived from a principle of rationality (the categorical imperative). As an example of the latter, Hume famously claimed that reason is “the slave of the passions” and that moral judgments stem from the moral emotions.

For moral realists moral judgments will be a kind of factual judgment that involves the basically reliable apprehension of an objective moral reality. I argue that factual judgments display at least some degree of conceptual sensitivity to error, while moral judgments do not. Therefore moral judgments are not a kind of factual judgment.

Sunstein's review of research on moral heuristics is rich and informative – even without his central claim that individuals often commit moral errors. We question the value of positing such a normative moral framework for the study of moral judgment. We also propose an alternative standard for evaluating moral judgments – that of subjective rationality.

Marc Hauser, Liane Young, and Fiery Cushman’s paper is an excellent contribution to a now resurgent attempt (Dwyer, 1999; Harman, 1999; Mikhail, 2000) to explore and understand moral psychology by way of an analogy with Noam Chomsky’s pathbreaking work in linguistics, famously suggested by John Rawls (1971). And anyone who reads their paper ought to be convinced that research into our innate moral endowment is a plausible and worthwhile research program. I thus begin by agreeing that even if the linguistic analogy turns out to be weak, it can do titanic work in serving, "as an important guide to empirical research, opening doors to theoretically distinctive questions that, to date, have few answers" (p. XXX). Granting the importance of the empirical investigation of moral judgment generally, and of research designed to probe the linguistic analogy specifically, I will nonetheless argue that there is simply no evidence that there is a specialized moral faculty, no evidence that the stronger version of the linguistic analogy is correct (p. XXX).

Is the science of moral cognition usefully modeled on aspects of Universal Grammar? Are human beings born with an innate "moral grammar" that causes them to analyze human action in terms of its moral structure, with just as little awareness as they analyze human speech in terms of its grammatical structure? Questions like these have been at the forefront of moral psychology ever since John Mikhail revived them in his influential work on the linguistic analogy and its implications for jurisprudence and moral theory. In this seminal book, Mikhail offers a careful and sustained analysis of the moral grammar hypothesis, showing how some of John Rawls' original ideas about the linguistic analogy, together with famous thought experiments like the trolley problem, can be used to improve our understanding of moral and legal judgment. The book will be of interest to philosophers, cognitive scientists, legal scholars, and other researchers in the interdisciplinary field of moral psychology.

Inspired by the success of generative linguistics and transformational grammar, proponents of the linguistic analogy (LA) in moral psychology hypothesize that careful attention to folk-moral judgments is likely to reveal a small set of implicit rules and structures responsible for the ubiquitous and apparently unbounded capacity for making moral judgments. As a theoretical hypothesis, LA thus requires a rich description of the computational structures that underlie mature moral judgments, an account of the acquisition and development of these structures, and an analysis of those components of the moral system that are uniquely human and uniquely moral. In this paper we present the theoretical motivations for adopting LA in the study of moral cognition: (a) the distinction between competence and performance, (b) poverty of stimulus considerations, and (c) adopting the computational level as the proper level of analysis for the empirical study of moral judgment. With these motivations in hand, we review recent empirical findings that have been inspired by LA and which provide evidence for at least two predictions of LA: (a) the computational processes responsible for folk-moral judgment operate over structured representations of actions and events, as well as coding for features of agency and outcomes; and (b) folk-moral judgments are the output of a dedicated moral faculty and are largely immune to the effects of context. In addition, we highlight the complexity of the interfaces between the moral faculty and other cognitive systems external to it (e.g., number systems). We conclude by reviewing the potential utility of the theoretical and empirical tools of LA for future research in moral psychology.

Moral psychologists have recently turned their attention to a phenomenon they call 'moral dumbfounding'. Moral dumbfounding occurs when someone confidently pronounces a moral judgment, then finds that he or she has little or nothing to say in defense of it. This paper addresses recent attempts by Jonathan Haidt and Marc Hauser to make sense of moral dumbfounding in terms of their respective theories of moral judgment; Haidt in terms of a 'social intuitionist' model of moral judgment, and Hauser in terms of his 'Rawlsian creature' model of moral judgment. I show that Haidt and Hauser assume that moral dumbfounding is to be explained in terms of features of a.) moral judgment that are b.) construed in terms of the intrinsic features of individuals. By contrast, I hypothesize that moral dumbfounding is to be explained in terms of moral reasoning, more specifically in terms of the social dynamics of such reasoning. Finally, I argue that this hypothesis points towards an externalistic account of both moral reasoning and moral judgment.
