Abstract
In this book, Michael Davis, one of the most insightful writers on professional ethics, substantially revises and integrates fifteen of his previously published articles, making them available to a wider audience. Several professions are emphasized: law, engineering, and police work (including international law enforcement). Yet the topics discussed have relevance to all areas of professional ethics: defining professions, the moral authority of professional codes, intelligently interpreting codes, professional autonomy and discretion, dirty hands, and goals in teaching professional ethics.
