I teach business ethics at the college level, and have found Ethical Theory and Business to be very helpful. Basically, B and B attempt to do three things, or so it seems to me. First, they offer an introductory essay, covering some of the main distinctions in both meta-ethics (e. g. whether morality is objective or subjective) and normative ethics. This essay is the weakest part of the book, I think, because they seem to offer caracatures of most relativist leaning views (e. g. egoism), and do not adequately criticize Kantian moral philosophy. But even so, the essay does explain many useful distinctions in philosophical ethical thought. Second, B and B offer both classic readings in Business Ethics (e. g. Milton Friedman), as well as really up to date readings, by many of the leaders in the field (e. g. R. Edward Freeman). This is quite a good selection of readings, although they have omitted a few classic essays (like Galbraith's 'The Dependence Effect'), and a few subjects which might have been useful, such as the question of whether one can attribute moral agency to corporations at all. Even so, B and B include more than any course in Business Ethics could cover. Third, B and B provide a Web site with excersizes and instructor aids. Depending on how much one uses the Web, this may be helpful too. So generally speaking, although no anthology is perfect, Beauchamp and Bowie have put together an admirable collection. There is a seventh edition coming out soon. Perhaps that one will be as good as this one.
