For Rawls, in order to have a stable and just society whose free and equal citizens are deeply divided by conflicting and even incommensurable doctrines, there is a need to posit a political conception of justice which will be a freestanding view and therefore independent but not conflicting with these comprehensive doctrines. This is the liberal political conception of justice as fairness. This political conception tries to seek social unity through political stability. It is seen in the idea of overlapping consensus. Discussions to critique, defend, and construct overlapping consensus are imperative. To substantiate, this discourse is to test the preconditions for justice as fairness and the main ideas of political liberalism. To pose: How are we to construct overlapping consensus given the fact of reasonable pluralism, that is, what could be the procedural mechanisms and substantive principles such Overlapping Consensus must have to articulate justice as fairness?
