A solid and relatively brief review of moral psychology and the conscience. A little more philosophical and abstract than I prefer, but informative and provocative.

The aptly named Churchland has written a thoughtful and well-researched tome on the idea of "conscience," a term we know without having a precise definition. She delves into brain science that has hardwired us to feel moral obligation for certain things, talks about societal influence, and points out that we may observe the same happening or read the same text as another person, but our consciences will tell us to react differently from each other--or we may even feel conflicted within ourselves. Will appeal to readers who enjoy books about religion, philosophy, and science.
