 Scanlon’s method of construction is the contractualist formula according to which an act is wrong if its performance under the circumstances would be prohibited by any set of principles that no one could reasonably reject as a basis for informed, unforced, general agreement. This test of rejectability specifies the content of moral principles, and tells us why it is rational for us to adopt them. The correctness of moral principles is explained in terms of a hypothetical agreement among the relevant set of individuals specified in terms of their motivation and the process of reasoning they employ. There are no correct moral principles independently of the rational agreement that the criterion of rejectability specifies. The property of being right is constituted by what a group of reasonable agents, under certain specified conditions, would find non-rejectable (Scanlon 1998: 380 n 48).
