While contractualism only provides an account of that central part of morality which deals with what we owe to each other, Scanlon writes that this part of morality is related to the broader realm of morality in complex ways. There is pressure for the morality of what we owe to each other to acknowledge the values included in the broader realm of morality insofar as principles which don't make room for these values could be reasonably rejected. In turn, these values must accommodate the dictates of what we owe to each other to the extent that they involve relations with others, who have separate moral standing.
