 If Cohen is right, then wide reflective equilibrium is not relevant to choosing between Rawls's account of justice and some other theory (such as luck egalitarianism), because we must restrict ourselves to a different, much narrower, version of reflective equilibrium to justify principles of justice. It would be odd to make such a substantive issue depend on a metaethical claim that Cohen himself says is not a substantive claim about which principles of justice are to be believed or accepted.
