 Under political liberalism, autonomy of persons is postulated, not as a metaphysically grounded “fact” about moral personality or practical reason as such, but rather as one of several “device[s] of representation” under which diverse citizens can focus on the methods of derivation (such as the original position) for substantive principles of justice (Rawls 1999, 303–58). Justice is achieved only when an overlapping consensus among people moved by deeply divergent but reasonable comprehensive moral views can be attained, a consensus in which such citizens can affirm principles of justice from within those comprehensive views.
