The political culture of a democratic society is always marked by a diversity of opposing and irreconcilable religious, philosophical, and moral doctrines. Some of these are perfectly reasonable, and this diversity among reasonable-doctrines political liberalism sees as the inevitable long-run result of the powers of human reason at work within the background of enduring free institutions. Thus, political liberalism looks for a political conception of justice that we hope can gain the support of an overlapping consensus of reasonable religious, philosophical, and moral doctrines in a society regulated by it. Political liberalism, then, aims for a political conception of justice as a freestanding view. It offers no specific metaphysical or epistemological doctrine beyond what is implied by the political conception itself.
