Abstract

How are we to understand the claim that, morally speaking, one ought to do the best one can? We must, of course, refer at some point to a substantive moral theory to flesh out the evaluative term “best,” and much of moral philosophy is devoted to defending one or another such theory. But Michael Zimmerman proposes that moral theorizing may be usefully served by a prior and separate metaethical enterprise—viz., a formal analysis of the concept of moral obligation. This analysis is undertaken in Zimmerman’s recent book.
