Moral Development & Reality: Beyond the Theories of Kohlberg and Hoffman Book

This wide survey of literature on personal identity is simultaneously a basic survey of literature on selfhood and soul but with disciplined exploration and development of topics. It must be a textbook but it seems much more to me in clearly written descriptions and interdisciplinary depth. I struggled with it a few years ago because I did not consider its actual intention which is to review the field from ancient times to the present. It combines psychology and philosophy, which at my university the two departments tried to keep students under each domaine isolated from the other though faculty members did engage each other. I am not quite certain how to weigh this work because I think the authors intentionally avoid "solving" or "resolving" issues encountered.
