Reflections on Four Case Studies in Ethics Ethics, or moral philosophy, investigates concepts of right and wrong conduct; it is not limited to the acts of a single person but seeks also reasoned, principled, positions vis-Ă -vis the practices of corporations, governments, and many other groups. Using the case method, a teaching approach that uses decisionforcing role-play, this prĂŠcis explores four dramatically different ethical dilemmas at individual, group, corporate, and global levels.
