Off Her Trolley? Frances Kamm and the Metaphysics of Morality

Frances Kamm's aptly titled Intricate Ethics is a tour de force of what Peter Unger calls the ‘preservationist’ approach to ethical theory. Here is some of what she says about her methodology: Consider as many case-based judgments of yours as prove necessary. Do not ignore some case-based judgments, assuming they are errors, just because they conflict with simple or intuitively plausible principles that account for some subset of your case-based judgments. Work on the assumption that a different principle can account for all of the judgments. Be prepared to be surprised at what this principle is . . . . I say, consider your case-based judgments, rather than a survey of everyone's judgments. This is because I believe that much more is accomplished when one person considers her judgments and then tries to analyze and justify their grounds than if we do mere surveys. (5)
