A person who sees that she morally ought to do something might wonder whether it would make sense for her to do it. Perhaps Aurelia is on a crowded bus, standing next to an old man whose wallet is almost falling out of his pocket. She says, “I see that the morally right thing would be to warn this man to take care of his wallet. But why should I do the right thing? In fact, why shouldn't I steal his wallet? It would be wrong of me to do this, but so what? No one is looking. I won't get caught. What's to fear?“We can imagine different scenarios of this kind. In one scenario, Aurelia is on the verge of deciding to steal the old man's wallet. She believes it would be wrong to do this, and she is asking whether there is any reason not to go ahead.

'Internalism’ in ethics is a cluster of views according to which there is an ‘internal’ connection between moral obligations and either motivations or reasons to act morally; ‘externalism’ says that such connections are contingent. So described, the dispute between internalism and externalism may seem a technical debate of minor interest. However, the issues that motivate it include deep problems about moral truth, realism, normativity, and objectivity. Indeed, I think that some philosophers view externalism as undermining the ‘dignity’ of morality. They might say that if morality needs an ‘external sanction’ - if the belief that one has an obligation is not sufficient motive or reason to do the right thing- then morality is debased in status. Even an arbitrary system of etiquette could attract an external sanction under appropriate conditions.Although I believe that the more interesting internalist theses are false, there are important truths that internalism is attempting to capture. The most important of these is the fact that moral judgments are intrinsically ‘normative’ or ‘choice-guiding,’ that they are, very roughly, relevant to action or choice because of their content.

The Oxford Handbook of Ethical Theory is a major new reference work in ethical theory consisting of commissioned essays by leading moral philosophers. Ethical theories have always been of central importance to philosophy, and remain so; ethical theory is one of the most active areas of philosophical research and teaching today. Courses in ethics are taught in colleges and universities at all levels, and ethical theory is the organizing principle for all of them. The Handbook is divided into two parts, mirroring the field. The first part treats meta-ethical theory, which deals with theoretical questions about morality and moral judgment, including questions about moral language, the epistemology of moral belief, the truth aptness of moral claims, and so forth. The second part addresses normative theory, which deals with general moral issues, including the plausibility of various ethical theories and abstract principles of behavior. Examples of such theories are consequentialism and virtue theory. As with other Oxford Handbooks, the twenty-five contributors cover the field in a comprehensive and highly accessible way, while achieving three goals: exposition of central ideas, criticism of other approaches, and putting forth a distinct viewpoint.

This chapter begins by explaining the distinction between meta-ethics and normative ethics. It then introduces the main issues in the two fields and provides a critical overview of the chapters in the volume. In meta-ethics, it focuses on explaining the different kinds of moral realism and anti-realism, including the divine command theory, naturalism, non-naturalism, relativism, nihilism, and non-cognitivism. Quasi-realism illustrates how the distinction between anti-realism and realism can become blurred. A variety of views about the relation between morality and practical reason, including contractarianism, are discussed. In normative ethics, the chapter focuses on the distinction, among theories of right action, between consequentialism and non-consequentialism, as well as the distinction between theories of right action and other kinds of normative theory, such as rights theory, virtue theory, and the ethics of care. There is an overview of the debate between consequentialism and deontology regarding moral constraints, as well as a discussion of indirect consequentialist responses to deontological objections.
