In his chapter, Steve Sapontzis presents a discussion of morality focusing on its origin and purpose in human psychology. Contrary to what might be expected, a humanistic idea of morality need not limit moral concern to inter-human relations. This is because, he argues, the purpose of morality is to reinforce our other-centered feelings in their struggle with human selfishness, and the class of others whose well-being motivates us is not limited to human beings. The chapter concludes with some practical inferences for nonhuman animal liberation from this idea of morality.
