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.

Despite recent efforts to improve on counterfactual theories of causation, failures to explain how effects depend on their causes are still manifest in a variety of cases. In particular, theories that do a decent job explaining cases of causal preemption have problems accounting for cases of causal intransitivity. Moreover, the increasing complexity of the counterfactual accounts makes it difficult to see why the concept of causation would be such a central part of our cognition. In this paper, I propose an account of our causal thinking that not only explains the hitherto puzzling variety of causal judgments, but also makes it intelligible why we would employ such an elusive concept.

Skeptical worries about moral responsibility seem to be widely appreciated and deeply felt. To address these worries—if nothing else to show that they are mistaken—theories of moral responsibility need to relate to whatever concept of responsibility underlies the worries. Unfortunately, the nature of that concept has proved hard to pin down. Not only do philosophers have conflicting intuitions; numerous recent empirical studies have suggested that both prosaic responsibility judgments and incompatibilist intuitions among the folk are influenced by a number of surprising factors, sometimes prompting apparently contradictory judgments. In this paper, we show how an independently motivated hypothesis about responsibility judgments provides a unified explanation of the more important results from these studies. According to this ‘Explanation Hypothesis’, to take an agent to be morally responsible for an event is to take a relevant motivational structure of the agent to be part of a significant explanation of the event. We argue that because of how explanatory interests and perspectives affect what we take as significant explanations, this analysis accounts for the puzzling variety of empirical results. If this is correct, the Explanation Hypothesis also provides a new way of understanding debates about moral responsibility.
