Every theory of justice requires a first-order theory specifying principles of justice, and a second-order view explaining why those principles constitute the correct principles of justice. According to John Rawls, political liberalism is committed to the two principles of justice specified in its first-order theory, “justice as fairness.” Justice as fairness, according to Rawls, in turn presupposes the second-order view that justice is a political conception. A political conception of justice treats the principles derived from the fundamental ideas in the public political culture as the correct principles of justice. Political liberalism, however, nowhere offers a defense of the view that justice is a political conception. Indeed, it even strives to avoid the admission that it presupposes that justice is a political conception by stating only that it uses a political conception of justice, while allowing that justice might not actually be a political conception. As to the truth of its second-order presupposition, political liberalism chooses to remain agnostic. Rawls claims that political liberalism has no choice at all. To do otherwise, he argues, would lead to an internal contradiction.
