““Ethics is [...] the philosophic branch of inquiry which talks about right and wrong, which talks about our moral obligations, which inquires into our certainty of what we ought and ought not to do. Ethics asks, "What is it to be a human being, and to engage in actions that are appropriate to a human being? [...] investigates the part of human beings that are not animals, that are not specifically, completely, part of nature.It investigates the element in human beings which make choices, which are free, which, in the ancient intellectual tradition, "have souls.””
