The theory of obligation addresses the central ethical question of what we ought to do. The theory of moral creditworthiness concerns motivation appropriate to fulfilling obligation. The theory of manners of actions concerns how they are performed. The triple-barreled theory of moral conduct the book develops integrates these dimensions of behavior. The theory covers obligatory deeds – the types of things we ought to do – the vehicles of conduct: concrete doings that are right or wrong in virtue of their type, morally or non-morally motivated by intentions that explain them, and morally appropriate or inappropriate in manner in virtue of how they are performed. Among the central moral principles examined are those of justice and harm-avoidance, veracity and fidelity, beneficence and self-improvement, and reparation and gratitude. How are these to be understood? Are some reducible to others? This chapter clarifies these principles through both narrative examples and conceptual exploration.
