Disjunctive duties and supererogatory sets of actions

  • Matthias Brinkmann (a1)

Extract

James Urmson famously claimed that all ethical theories which only operate with the three deontic categories of the required, the optional, and the forbidden were ‘totally inadequate to the facts of morality’ because they fail to recognise a fourth category of actions, which we can call the supererogatory. Supererogatory actions should be seen as ‘meritorious non-duty’, as something which is good but in no sense required. A number of examples can be provided to make the existence of such a realm outside duty plausible: the soldier throwing herself on a live hand grenade to save her companions, the torture victim who forgives her tormentors even though they do not regret, or the doctor who voluntarily travels to a war zone to treat the wounded.

11 I will explain these last caveats in subsections 6.3 and 6.4.

15 One action can be disjunctively required as a member of different sets.

17 For similar definitions, see ibid., 508–9, and Statman, Daniel, ‘Who Needs Imperfect Duties?’, American Philosophical Quarterly 33 (1996): 211–24, at 213.

LaFollette (ed.), International Encyclopedia of Ethics (Chichester: Blackwell, 2013), vol. 8, 5070–78; Gregory Trianosky, ‘Supererogation’ in E. Craig (ed.), Routledge Encyclopedia of Philosophy (London: Routledge, 1998), vol. 9, 232–5.

19 Omissions can also be supererogatory. Assume that a homeless person starts living in Sindhu's garage. Sindhu has not invited or encouraged that person to stay, but she also does nothing to expel the homeless from her garage. This, plausibly, is a supererogatory omission. But for simplicity's sake I will only talk of ‘actions’ rather than ‘actions and omissions’ in the main text. (Thanks to an audience member at the Dublin conference for pointing this out.)

20 Derek Parfit calls it a ‘mistake in moral mathematics’ to ignore the effects of ‘sets of acts’, but he has inter-personal, not intra-personal cases, in mind (Reasons and Persons (Oxford: Clarendon Press, 1984), sec. 26).

21 I thank an anonymous reviewer for pressing me on these issues.

22 I will return to this case in sec. 6.

23 This reply has been suggested to me by David Heyd.

24 For the objection that it isn't, see below.

25 This might be Urmson's response. See discussion below, and Burchill, Lorenne, ‘In Defence of Saints and Heroes’, Philosophy 40 (1965), 152–7, at 152–3.

26 I thank an anonymous reviewer for raising this point.

27 Op. cit. note 1, 205.

28 See also the examples in subsection 5.1.

29 Op. cit. note 3, 63.

30 This is inspired by Parfit-style cases; see op. cit. note 20.

31 Op. cit. note 2, 280.

32 Heyd, op. cit. note 3, 125. Emphasis in original.

33 Guevara thinks that for this reason we should not define supererogation in terms of acts which do not fulfill any duties (op. cit. note 7, 595–7).

34 This is a modification of an argument in Gregory Mellema, Beyond the Call of Duty: Supererogation, Obligation, and Offence (Albany: State University of New York Press, 1991), 34–6. Cf. Mellema, Gregory, ‘Supererogation and the fulfillment of duty’, Journal of Value Inquiry 25 (1991), 167–75, at 171–3.

37 Marcia Baron's term.

38 Statman, op. cit. note 17, 212–3; Baron, op. cit. note 7, 250–2.

39 I thank Johannes Himmelreich, Jessica Laimann, and Maxime Lepoutre for comments, the audience at the Dublin ‘Supererogation’ conference, and an anonymous reviewer. I also received helpful feedback on an early version of this paper from Hasko von Kriegstein, Marco Meyer, and Andreas Schmidt. Lastly, I thank Matthew Braham without whose encouragement this paper would not exist.
