This paper critically examines moral contractarianism, a moral theory centred on rational agreements among self-interested individuals to establish moral rules and social norms. It explores the challenges faced by moral contractarianism while also highlighting its strengths. Major issues, such as accommodating justice and fairness within the contractarian framework, are discussed, along with other challenges. Additionally, the paper provides a brief discussion of moral contractualism (a theory similar to moral contractarianism in certain aspects), highlighting its strengths in addressing some of the (...) challenges faced by moral contractarianism while also discussing its limitations. The paper concludes by offering a revised framework of moral contractarianism that provides solutions to the major problems of injustice and partiality that the theory faces. (shrink)
