 The only reasons for and against a principle that count when we are judging whether or not it can be reasonably rejected are “various individuals’ reasons for objecting to that principle and alternatives to it” (Scanlon 1998, p. 229). The acceptability of a principle depends on a one-by-one assessment of the strength of the reasons that individuals would have for rejecting the principle, compared to the alternatives to it. Since individuals must be objecting on their own behalf and not on behalf of a group, this restriction to single individuals’ reasons bars the interpersonal aggregation of complaints; it does not allow a number of lesser complaints to outweigh one person’s weightier complaint.
