Stephen Stich takes us on a journey through recent moral philosophy, meta-ethics, numerous studies in moral psychology, a discussion of the moral/conventional task, and some interesting moral dilemmas, in an attempt to define morality.
Lots of interesting things to consider.

Stich is primarily known in philosophy for his work in the philosophy of mind, cognitive science, epistemology, and moral psychology. In philosophy of mind and cognitive science, Stich (1983) has argued for a form of eliminative materialism—the view that talk of the mental should be replaced with talk of its physical substrate. Since then, however, he has changed some of his views on the mind. See Deconstructing the Mind (1996) for his more recent views. In epistemology, he has explored (with several of his colleagues) the nature of intuitions using the techniques of experimental philosophy, especially epistemic intuitions that vary among cultures. This work reflects a general skepticism about conceptual analysis and the traditional methods of analytic philosophy. In The Fragmentation of Reason he briefly sketched a form of epistemic relativism "in the spirit of pragmatism."
