Interpersonal aggregation involves the combining and weighing of benefits and losses to multiple individuals in the course of determining what ought to be done. Most consequentialists embrace thoroughgoing interpersonal aggregation, the view that any large benefit to each of a few people can be morally outweighed by allocating any smaller benefit to each of many others, so long as this second group is sufficiently large. This would permit letting one person die in order to cure some number of mild headaches instead. Most non-consequentialists reject thoroughgoing interpersonal aggregation despite also believing it is permissible to let one person die in order to prevent many cases of paraplegia instead. Non-consequentialists defend this asymmetry largely on the basis of intuition, and some rely on the notion of relevance to formalize the grounding intuitions. This article seeks to clarify and strengthen the non-consequentialist notion of relevance by engaging with three objections to it.

7 Derek Parfit thinks this is a serious problem for a view which invokes the notion of relevance (what Parfit calls ‘The Close Enough View’). Whether this is in fact a serious problem turns in part on whether there can be moral dilemmas and whether this might be one. I lack the space to discuss this adequately here.

14 It is worth noting that what Norcross calls deontic ‘intransitivity’ is arguably not really a form of intransitivity at all. As Daniel M. Hausman explains, ‘[T]ransitivity concerns preferences over a single set of alternatives. Transitivity says nothing about how preferences over one set of alternatives {apple pie, blueberry pie} should be related to preferences over a different set of alternatives {apple pie, blueberry pie, cherry pie}.’ See Hausman, D. M., Preference, Value, Choice and Welfare (Cambridge, 2012), pp. 15–16Google Scholar.

21 This case was inspired by a case presented by Daniels, Norman in ‘Reasonable Disagreement about Identified vs. Statistical Victims’, Hastings Center Report 42 (2012), pp. 35–45, at 41CrossRefGoogle Scholar.

Statistical Lives: Ethical, Legal, and Medical Perspectives, ed. Cohen, I. Glenn, Daniels, Norman and Eyal, Nir (Oxford, in press)Google Scholar. Unaware of Frick's work at the time, I discussed the ex post view in ‘Prevention, Rescue, and Tiny Risks’, Public Health Ethics 6 (2013), pp. 252–61, under the name of ‘Brock and Wikler's view’ of how to assess the strength of claims.
23 A notable exception is Taurek, J., ‘Should the Numbers Count’, Philosophy and Public Affairs 6 (1977), pp. 293–316Google ScholarPubMed.
24 I deploy this case to make similar point in ‘Prevention’.
25 Of course, both defenders and opponents of the ex post view can agree that Alice's antecedent risks gave us good epistemic reason to believe that Alice had a strong claim. But that is the only role that proponents of the ex post view give to antecedent risks, and this is what makes that view so implausible.
26 See again Kelleher, ‘Prevention’, and Frick, ‘Treatment vs Prevention’.
27 The argument from tiny risks therefore provides reasons to join Kamm in talking about (ir)relevant goods, rather than (ir)relevant claims. See Kamm, Intricate Ethics: Rights, Responsibilities, and Permissible Harm (Oxford, 2007), p. 34.
