Abstract

This is a review essay of Jeff McMahan's recent book The Ethics of Killing : Problems at the Margins of Life. In the first part, I lay out the central features of McMahan's account of the wrongness of killing and its implications for when it is permissible to kill. In the second part of the essay, I argue that we ought not to accept McMahan's rejection of species membership as having any bearing on whether it is permissible to kill a particular individual, as there are ways of understanding its relevance that are more plausible than McMahan allows
