Abstract

This thesis is a critique of the prominent strand of contemporary liberal political theory which maintains that liberal political authority must, in some sense, rest on the free consent of those subjected to it, and that such a consensus is achieved if a polity’s basic structure can be publicly justified to its citizenry, or to a relevant subset of it. Call that the liberal legitimacy view. I argue that the liberal legitimacy view cannot provide viable normative foundations for political authority, for the hypothetical consensus it envisages cannot be achieved and sustained without either arbitrarily excluding conspicuous sectors of the citizenry or commanding a consent that is less than free. That is because the liberal legitimacy view’s structure is one that requires a form of consent that carries free-standing normative force, yet the particular form of hypothetical consent through public justification envisaged by the view does not possess such force, because of its built-in bias in favour of liberalism. I also argue that the liberal legitimacy view is the most recent instantiation of one of two main strands of liberal theory, namely the nowadays dominant contract-based liberalism, which seeks to ground liberal political authority in a hypothetical agreement between the citizens. My case against the liberal legitimacy view, then, contributes to the revitalisation of the other main approach to the normative foundations of liberalism, namely the substantivist one, which legitimates liberal political authority through an appeal to the substantive values and virtues safeguarded and promoted by liberal polities.
