According to T. M. Scanlon's contractualist view thinking about right and wrong is thinking
about what we do in terms that could be justified to others and that they could not reasonably
reject. He shows how the special authority of conclusions about right and wrong arises from the
value of being related to others in this way and he demonstrates how familiar moral ideas such
as fairness and responsibility can be understood through their role in this process of mutual
justification and criticism.
