The Ethical Brain
In The Ethical Brain, neurologist Michael Gazzaniga, who served on the President's Council on Bioethics, tries to apply his knowledge of neurology to tackle various ethical problems. While he brings up some important questions, his answers are disappointing. Though I agree with him more often than not, he generally states his conclusions without providing a solid justification. Since I've read better books on the nature of the mind, I can't recommend this one.
