This book defends morality against the critiques of egoims, subjectivism, and relativism. It argues that we can and should construe some moral standards as objective and that justice and self-development are the cornerstones of healthy morality. Opening with a dialogue meant to tease and provoke the reader, the book's subsequent chapters treat misconceptions about morality, the possibility of unselfish action, the nature of free will and moral responsibility, and the identity of moral right and wrong.
