I argue that moral judgement is a natural kind on the grounds that it plays a causal/explanatory role in psychological generalizations. I then develop an empirically grounded theory of its identity as a natural kind. I argue that moral judgement is a hybrid state of moral belief and moral emotion. This hybrid theory supports the role of moral judgement in explanations of reasoning and action and also supports its role in a dual process model of moral cognition. Although it is (...) composed of moral belief and moral emotion, moral judgement is unified, like other natural kinds, in virtue of underlying mechanisms that generate homeostasis among its components. Finally, this theory about the unity of moral judgement resolves a longstanding puzzle about moral motivation. The view explains how it is that moral judgements motivate all on their own but not all the time. (shrink)

It is more than a half-century since Nelson Goodman [1955] applied what we call the Reflective Equilibrium model of justification to the problem of justifying induction, and more than three decades since Rawls [1971] and Daniels [1979] applied celebrated extensions of this model to the problem of justifying principles of social justice. The resulting Wide Reflective Equilibrium model (WRE) is generally thought to capture an acceptable way to reconcile inconsistency between an intuitively plausible general principle and an intuitively plausible judgment (...) about a particular case. Recently a different model for reconciling moral inconsistency has emerged: Moral Consistency Reasoning [Campbell and Kumar 2012, 2013a; Kumar and Campbell 2012; Campbell 2009: 86?7; Campbell and Woodrow 2003; Wong 2002]. MCR applies when two moral judgments give opposing assessments of (what appear to be) relevantly similar particular cases. Though WRE and MCR are strikingly different, each arguably captures a rationally acceptable method for reconciling moral inconsistency. Moreover, as will be shown, they function in complementary ways. Are they parts of a more comprehensive model of moral reasoning in the face of inconsistency that would explain the attractions of each? This essay first spells out the relevant differences between the models and then formulates a more general model of moral reasoning in the face of inconsistency. ?1 reviews the emergence of Goodman's model that he offers in the spirit of epistemology naturalized, almost a decade before Quine coined the term [1969a]. ?2 analyses six salient features of WRE to be compared with six contrasting features of MCR in ?3. ?4 presents the general model.
