This chapter examines circumstantial luck, or the luck of being in circumstances where a moral response or course of action is called for. The anti-anti-luckist programme is maintained for circumstantial luck as well as resultant luck. The argument proceeds, first, through an examination of Good Cases, calling for praiseworthiness. The fact that a well-intentioned agent is not in a position to collect praise for performing a meritorious act does not generate any serious moral concern. We can still praise this inactive agent for her dispositions if we wish to, and morality does not insist, in any case, upon equal opportunities for collecting praise. These lessons are then transferred to Bad Cases, calling for blameworthiness. The chapter also engages in detail with Michael Zimmerman’s argument involving situational luck, which combines circumstantial luck with constitutive luck. Zimmerman’s radical argument suggests that one agent should be no more blameworthy than another agent if they are separated only by luck, whether of the resultant, circumstantial, or constitutive variety. It is suggested here that Zimmerman’s argument misfires, due to an inconsistency between two principles he relies upon: the ‘Control Principle’ and the ‘No-Difference Claim’.
