In his new book, The Dimensions of Consequentialism, Martin Peterson proposes a version of multi-dimensional consequentialism according to which risk is one among several dimensions. We argue that Peterson’s treatment of risk is unsatisfactory. More precisely, we want to show that all problems of one-dimensional (objective or subjective) consequentialism are also problems for Peterson’s proposal, although it may fall prey to them less often. In ending our paper, we address the objection that our discussion overlooks the fact that Peterson’s proposal is not the best version of multi-dimensional consequentialism. Our reply is that the possibilities of improving multi-dimensional consequentialism are very limited as far as risk is concerned
