The reality and validity of the moral sense ? which ordinary people take for granted ? took a battering in the last century. Materialist trends in philosophy, decline in religious faith, and a loosening of traditional moral constraints contributed to a shift in public attitudes, with many decent honest folk both aware of a questioning of moral claims and uneasy with a world that has no place for the moral dimension. Haslam shows how important the moral sense is to the human personality and exposes the weakness in much current thinking that suggests otherwise. His goal is to help the reader to a mature and confident understanding of the moral mind, which constitutes an essential part of what it is to be human.
