 As we saw in section 3.2, contractualism allows for the reasonable rejection of principles on grounds other than their direct impact on the individual’s well-being. However, this appeal to reasons beyond well-being brings out a common objection to contractualism—that the whole apparatus of reasonable rejection is redundant. The objection is as follows. Contractualism says x is wrong if and only if x is forbidden by principles no-one can reasonably reject. Anyone can reasonably reject a principle on the grounds that it permits actions that are wrong. So a principle that no-one can reasonably reject is a principle that permits no actions that are wrong. If we don’t already know which actions are wrong, then we cannot use the contractualist apparatus. But if we do already know which actions are wrong, then we don’t need to use it.
