 The problem of moral luck is deeply unsettling. Naturally, there is a wide variety of responses to it. On the one extreme are those who deny that there is any sort of moral luck, and on the other are those who accept every sort of moral luck. Most writers who have responded to the problem fall somewhere in between; either they explicitly take a mixed approach or they confine their arguments to a carefully delineated subset of types of moral luck while remaining uncommitted with respect to the others. The extreme positions are vulnerable to the objection that they have left some consideration or other completely unaccounted for. But those who occupy the middle also face a formidable challenge: where can one draw a principled line between acceptable and unacceptable forms of luck? As we have seen, one apparently natural place to draw a line is between resultant luck and all of the other sorts. On this view, there is no resultant moral luck, despite initial appearances, although there is moral luck of all the other kinds. Thus, occupiers of this position face the challenge of setting out a plausible rationale for drawing the line where they do. But they also face the challenge of where precisely to draw another line, namely, the line around what counts as “results.” For we can ask on which side of this line do intentions, willings, bodily movements, and so on, fall. Do results include everything that happens after the formation of an intention or the exertion of the will, for example? Or everything that follows the beginning of the formation of an intention or the beginning of the exertion of the will? Or everything that follows the “affection of the heart” of which Adam Smith wrote so eloquently? These are difficult questions for those who would draw a line at resultant luck. But difficult questions await every other proposal, too. Fortunately, there is a rich and growing literature providing a full spectrum of responses to explore.
