 Nagel seems inclined to think that the solution is to “set some limits on how possible a possibility must be for its nonrealization to be a misfortune,” but also mentions that we might not regard, as a misfortune, “any limitation, like mortality, that is normal to the species.” Draper suggests that harmless preclusion involves cases in which the events or states of affairs that would be good for us if they held are highly improbable (Draper 1999). Another explanation might focus on the relative importance of having some goods rather than others. In some moods, we may consider it harmful to be deprived of a good just when it is important for us to have it. The troublesome lacks we have been discussing might be lacks of goods it is unimportant to have; such lacks would not be harmful even though we would be better off without them. (But if, against all odds, a person is a genius, or rich, or beautiful, would taking these away be harmless to her?)
