 Scanlon (1998) does not attempt to deliver a theory of justice in the same sense as Rawls, but his contractarian account of that part of morality that specifies ‘what we owe to each other’ covers much of the same terrain (for an explicit attempt to analyse justice in Scanlonian terms, see Barry 1995). Like Rawls, Scanlon is concerned to develop an alternative to utilitarianism, and he does so by developing a test that any candidate moral principle must pass: it must be such that no-one could reasonably reject it as the basis for informed, unforced general agreement (see the entry on  contractualism).  Scanlon’s contractors are not positioned behind a veil of ignorance. They are able to see what effect adopting any proposed principle would have on them personally. If that effect is unacceptable to them, they are permitted to reject it. Each person has, so to speak, a veto on any general principle for regulating conduct. Those that survive this test are defensible as principles of justice – Scanlon concedes that there might be alternative sets of such principles appropriate to different social conditions.
