This volume collects the principal works of the late Warren Quinn. The papers cover a broad range of topics and may, for present purposes, be divided three ways, as variously concerning problems of metaethics, of the rationality of morality, and of substantive or practical ethics. I will not discuss Quinn’s great papers on abortion, punishment, double effect, and the distinction between killing and letting die—except to remark that they are united by an underlying anticonsequentialist program. They are, I think, his (...) best-known works. (shrink)
