This chapter has two sections, each focusing on a distinct way in which ethical disagreement and variations in ethical judgment matter for theories of ethical thought and talk. In the first section, we look at how the variation poses problems for both cognitivist and non-cognitivist ways of specifying the nature of ethical judgments. In the second, we look at how disagreement phenomena have been taken to undermine cognitivist accounts, but also at how the seeming variation in cognitive and non-cognitive contents between parties of deep ethical disagreement challenges both cognitivist and non-cognitivist accounts of disagreement itself.

Emotivists hold that moral opinions are wishes and desires, and that the function of moral language is to “express” such states. But if moral opinions were but wishes or desires, why would we see certain opinions as inconsistent with, or following from other opinions? And why should our reasoning include complex opinions such as the opinion that a person ought to be blamed only if he has done something wrong? Indeed, why would we think that anything is conditional on his doing something wrong unless “doing something wrong” signifies a real kind of action? Many have believed, and seemingly on good grounds, that these questions lack good answers, and that emotivism is doomed for that very reason. What I will argue, however, is that once emotivism is recognized for what it is, namely an empirical theory about the psychological nature of moral opinions, and once we relate it to a general theory of human reasoning, moral reasoning and intuitions of inconsistency and consequence are only to be expected. Recent objections to earlier emotivist or “expressivist” accounts can thus be met, and the phenomena of inconsistency and consequence fully embraced by emotivists.

An ancient but central divide in moral philosophy concerns the nature of opinions about what is morally wrong or what our moralduties are. Some philosophers argue that moral motivation is internal to moral opinions: that moral opinions consist of motivationalstates such as desires or emotions. This has often been seen as athreat to the possibility of rational argument and justification inmorals. Other philosophers argue that moral motivation is external to moral opinion: moral opinions should be seen as beliefs about moral reality, beliefs which may or may not motivate depending onwhether the person holding them cares about moral matters. In this essay it is argued that although the traditional case forthe internalist position fails, the total available evidence andmethodological considerations support an internalist theory formu-lated in terms of a relatively rich psychological model. It is shown how such a theory can explain not only the practical character of moral opinions and their connection to moral emotions but alsophenomena that have been taken to suggest an externalist picture,such as the role of inference, inconsistency, argument and explanations in moral discussion, as well as cases of amoralism and psychological disturbance. In the end, it is concluded that externalistexplanations of the same phenomena are methodologically inferiorfor postulating a more complicated psychology.
