As commonly understood, professional ethics consists of shared duties and episodic dilemmas--the responsibilities incumbent on all members of specific professions joined together with the dilemmas that arise when these responsibilities conflict. Martin challenges this consensus paradigm as he rethinks professional ethics to include personal commitments and ideals, of which many are not mandatory. Using specific examples from a wide range of professions, including medicine, law, high school teaching, journalism, engineering, and ministry, he explores how personal commitments motivate, guide, and give meaning to work.
