Contractualism is a constructivist attempt at providing a unified account of the subject matter of a central part of morality which Scanlon calls "what we owe to each other". The normative domain of what we owe to each other is meant to encompass those duties to other people which we bear in virtue of their standing as rational creatures. A broader conception of morality includes whatever else we may owe to specific people, such as the special obligations we bear in relations with friends and family, or whatever else morality may require of us, such as the way in which we treat ourselves or nature. Scanlon believes that what we owe to each other, or what we could loosely call "the morality of right and wrong", is distinct from this broader conception of morality in that contractualism provides a unified account of its content.
