Farewell to the modal theory of luck

The modal theory of luck, according to one influential version of it, holds that an event is lucky if and only if it actually obtains but fails to obtain in some close possible worlds, holding fixed certain initial conditions for the event. There have been some notable critiques of the theory. But they are not fully satisfactory, for they succumb to two typical and compelling strategies of defending the modal theory. By invoking a special fair lottery case, adapted from the well‐known Frankfurt cases on free will, this article presents a novel attack on the modal theory. As to be shown, there are cases where someone wins a fair lottery as a matter of good luck, yet there are no close possible worlds where he fails to win it. I also argue that the two typical and compelling strategies of defending the modal theory do not meet our challenge.
