Abstract

Richard Arneson and Alison McIntyre have done me a great honor by reading my book Ideal Code, Real World so carefully.1 In addition, they have done me a great kindness by reading it sympathetically. Nevertheless, they each find the book ultimately unconvincing, though in very different ways. But the cause of their dissatisfaction with the book is not mistaken interpretation. They have interpreted the book accurately, and they have advanced penetrating criticisms of it. One group of their criticisms definitely draw blood. To treat the wound, my formulation of rule-consequentialism will have to be revised. A second group their criticisms seems to me fatal only if certain considerations are ignored. I will highlight the considerations that I think inoculate rule-consequentialism against these criticisms. In reaction to a third group of their criticisms, however, I have to accept that Arneson and McIntyre simply have quite different intuitions from mine, such that the prospects of agreement between the three of us are dim.
