 It might seem, however, that giving each person a veto would lead straightforwardly to deadlock, since anyone might reject a principle under which he fared badly relative to some alternative. Here the idea of reasonable rejection becomes important. It would not, Scanlon thinks, be reasonable to reject a principle under which one does badly if the alternatives all involve someone else faring worse still. One needs to take account of other people’s reasons for rejecting these alternatives. It might then appear that Scanlon’s contractualism yields the difference principle, which requires the worst-off group in society to be as well of as they can be. But this is not the conclusion that Scanlon draws (though he acknowledges that there might be special reasons to follow Rawls in requiring basic social institutions to follow the difference principle). The claims of other groups must be considered too. If a policy greatly benefits many others, while slightly worsening the position of a few, though without leaving them very badly off, it may well not be rejectable. Scanlon’s position leaves some room for aggregation – it makes a difference how many people will be benefitted if a principle is followed – though not the simple form of aggregation that utilitarians defend.
