From this point, Scanlon's account of the value of rational life provides a focus around which his account of the reason-giving force of moral judgements dovetails quite neatly with a characterization of the method of reasoning which we use to arrive at judgements of right and wrong, a method, moreover, which seems to be phenomenologically plausible. The reason-giving force of moral judgements is grounded in an ideal of mutual recognition which requires treating others in accordance with principles that they could not reasonably reject. Because mutual recognition requires that these other people are also appropriately motivated, this entails Scanlon's formulation of wrongness: "An act is wrong if and only if any principle that permitted it would be one that could reasonably be rejected by people moved to find principles for the general regulation of behaviour that others, similarly motivated, could not reasonably reject". An act is right, quite simply, if a principle permitting it could not reasonably be rejected in terms of this contractualist formulation.
