In this book Robert Audi presents an original ethics of conduct, spanning moral theory, practical ethics, and theories of obligation and value. Conduct is determined not just by what we do, but also by why and how we do it. To integrate these dimensions of conduct, Audi clarifies the relation between intention and obligation, explains the difference between moral rightness and moral worth, and describes myriad manners of human actions. He also clarifies major moral standards such as justice, fidelity, beneficence, and liberty, and explores ethics from the perspectives of the theory of action, the epistemology of moral principles, the metaphysics of normative properties, and the value of human experiences. His concluding chapters offer a theory of reasons and values and propose an original theory of value.
