 The topic of moral reasoning lies in between two other commonly addressed topics in moral philosophy. On the one side, there is the first-order question of what moral truths there are, if any. For instance, are there any true general principles of morality, and if so, what are they? At this level utilitarianism competes with Kantianism, for instance, and both compete with anti-theorists of various stripes, who recognize only particular truths about morality (Clarke &amp; Simpson 1989). On the other side, a quite different sort of question arises from seeking to give a metaphysical grounding for moral truths or for the claim that there are none. Supposing there are some moral truths, what makes them true? What account can be given of the truth-conditions of moral statements? Here arise familiar questions of  moral skepticism  and  moral relativism;  here, the idea of “a reason” is wielded by many hoping to defend a non-skeptical moral metaphysics (e.g., Smith 2013). The topic of moral reasoning lies in between these two other familiar topics in the following simple sense: moral reasoners operate with what they take to be morally true but, instead of asking what makes their moral beliefs true, they proceed responsibly to attempt to figure out what to do in light of those considerations. The philosophical study of moral reasoning concerns itself with the nature of these attempts.
