  Luck is a pervasive feature of human life (Williams 1981, 21). It appears to arise in four main ways (Nagel 1979; Statman 1993, 11). First, the outcomes of our actions are affected by luck (resultant luck). In the mid-1990es it may have seemed prudent to take a degree in computer science; someone who did so and completed a course just before the IT bubble burst unforeseeably in 2000 may rightly see her ensuing unemployment as bad resultant luck. Second, the circumstances in which one acts introduce luck (circumstantial luck). A person who is offered proper incentives and plenty of time to deliberate may make a wiser decision than she would under less favorable conditions; it may be by accident that she finds herself in the favorable conditions and hence makes the wiser decision (but see Pritchard 2005, 254–261). Third, luck affects the kind of person you are (constitutive luck). Genetically, some people are at greater risk of cancer through smoking than others, and because of this it makes sense to say that some smokers are lucky to avoid cancer. Finally, there is luck in the way one’s actions are determined by antecedent circumstances (antecedent causal luck). Children who grow up in a stimulating environment perhaps become more motivated than they would in a duller setting; yet children rarely determine the time and place in which they are raised. When we add up resultant, circumstantial, constitutive, and antecedent causal luck, the area of life that is free of luck seems to shrink “to an extensionless point” (Nagel 1979, 35; compare Parfit 1995, 10–12; Levy 2014).
