1 Thanks are due to the Social Sciences and Humanities Research Council of Canada for their financial support during the time in which this paper was written, and to Shelly Kagan for his extensive comments on earlier versions of this work when it took the form of the fifth chapter of my doctoral dissertation at the University of Illinois at Chicago, ‘Thresholds for Rights.’

2 I will help myself to some of Judith Thomson’s terminology. In The Realm of Rights she refers to any failure to accord a rights claim as an infringement of that right, and refers to unjustified infringements as violations. This distinction is introduced in the course of her rejection of the claim that all rights are absolute or that every infringement is also a violation. See Judith Thomson, The Realm of Rights (Cambridge, MA: Harvard University Press 1990), 122. To these two terms I add my own ‘overriding,’ which is a justified infringement when the justification is on the basis of what is at stake for those will benefit from the rights infringement.

3 For example, I think that the threshold of a right has at least two components in addition to the total requirement. In my dissertation ‘Thresholds for Rights’ I argue that there is an existential constraint (which says that among those who will benefit from the infringement there must be at least one person who has [roughly] as much at stake as the right bearer, and a universal constraint (which says that for all beneficiaries of the infringement if what they have at stake is to count towards meeting the total, it must exceed a certain minimum amount-proportional to what the right bearer has at stake).

6 I phrase this in terms of B’s ‘proceeding’ since I do not mean to take a stand on whether some action, when performed by B, would count as an infringement of B’ s right. At the very least it seems to me that there are many cases where it would not count as an infringement of his right.

7 Shelly Kagan calls the feature of common sense morality which allows people to give up utility for themselves for the sake of others when there is a net loss in overall utility an ‘option of generosity.’ See Shelly, Kagan The Limits of Morality (Oxford: Clarendon Press 1989), 246-9Google Scholar.

8 For example, Michael Slote calls such features of common sense morality ‘self/ other asymmetries’ (’Morality and Self-Other Asymmetry,’ The Journal of Philosophy 81 [1984]179-92).

10 I am not endorsing the strong claim that we are in complete control of all of our rights. Such a position would entail the denial of there being any inalienable rights, and this is a controversy I do not wish to engage with here. I am only endorsing the weaker claim that we are in control of most of our rights and that this group includes the right not to be harmed, the right I most commonly talk about in my examples.
