 For each of the theses, Williams has something (at least one thing) of deep interest to say about why we should reject it. The first and second—about the practicality of morality and the impossibility of real conflict—are his target in his well-known early paper “Ethical Consistency” (PS: 166–186). In real life, Williams argues, there surely are cases where we find ourselves under ethical demands which conflict. These conflicts are not always eliminable in the way that the morality system requires them always to be—by arguments leading to the conclusion that one of the oughts was only prima facie (in Ross’s terminology: see Williams 1985: 176–177), or pro tanto (in a more recent terminology: see Kagan 1989), or in some other way eliminable from our moral accounting. But, Williams argues, “it is surely falsifying of moral  thought[13]  to represent its logic as demanding that in a conflict… one of the conflicting oughts must be totally rejected [on the grounds that] it did not actually apply” (PS:  183–4).[14]  For the fact that it did actually apply is registered by all sorts of facts in our moral experience, including the very important phenomenon of ineliminable agent-regret, regret not just that something happened, but that it was me who made it happen (1981: 27–30).
