It is often natural to compare two events by describing one as ‘more of a cause’ of some effect than the other. But what do such comparisons amount to, exactly? This paper aims to provide a guided tour of the recent literature on ‘degrees of causation’. Section 2 looks at what I call ‘dependence measures’, which arise from thinking of causes as difference‐makers. Section 3 looks at what I call ‘production measures’, which arise from thinking of causes as jointly sufficient (...) for their effects. Finally, section 4 examines the important question of whether there is any sense in which an agent is more responsible for an outcome in virtue of her action being more of a cause of it. I describe a puzzle that emerges from this question, and explore various strategies for resolving it. (shrink)

According to an influential view, ‘the amount of blame people deserve varies with the extent of their indifference’. That is, the more wrongdoers act from a lack of moral concern, the more they would be blameworthy. This paper argues for the exact opposite claim: the more wrongdoers act from indifference, the less they are blameworthy – that is, in a properly interpersonal way.
