"Hayek's political philosophy either invokes a number of different, and incompatible, moral theories to defend different claims, or lacks any normative moral theory at all. [...] Hayek presents three kinds of argument to defend his liberal social order and the conception of justice he sees at its heart. The first is a contractarian argument which invokes Kantian considerations to deny that patterning principles of social justice can be morally justified. The second is a conservative argument which not only points to the value of established traditions but also repudiates the claim that reason can present complete justifications for the rules governing any social order. The liberal order is preferred as that order which makes the fewest demands upon individual reason, for its principles of justice aim primarily at maintaining the abstract order of rules rather than at the rational reconstruction of society according to principles of distributive justice. The third is a utilitarian argument drawing attention to the beneficial consequences of a stable regime of liberal justice: progress and material prosperity. While each of these arguments appears in Hayek's work, none, as we have seen, can clearly be held to be fundamental."
