Public reason liberalism holds that laws and policies must be justifiable to all reasonable citizens. Recently, David Enoch has offered an impressive and influential argument against the epistemological commitments of public reason liberalism on the grounds that they are ‘highly controversial’. After setting out this argument (Sections I and II), I show how its central claim is ambiguous between two senses of ‘controversial’. This gives rise to a dilemma: either Enoch's claim is that the relevant epistemological commitments are controversial in (...) the sense of being subject to controversy amongst actual people, in which case this is true but not troubling for public reason theorists; or the claim is that the relevant commitments are controversial in the sense of being subject to controversy amongst reasonable people, in which case this simply begs the question against public reason theorists (Section III). I then defend each horn of the dilemma against objections (Sections IV and V). I conclude by generalizing this dilemma, showing how it defuses not just Enoch's argument but also a number of other arguments frequently made in the literature on public reason liberalism (Section VI).

A common objection to political liberalism is that since reasonable citizens agree that some ways of life are worse than others – for instance that the life of a drug addict is less worthwhile than the life of a person who spends her time with family and philosophy – political liberals must concede that the state can sometimes permissibly use perfectionist reasons. I argue in this paper that this challenge is mistaken, because the comparison only tells us something about relative, (...) not absolute, value. And because the real question concerns what the right justificatory constituency looks like, not what counts as reasonable in some other sense, the implication is that perfectionists and political liberals could construct equally plausible idealised constituencies. This stalemate gives us reason to develop arguments in favour of our preferred justificatory constituency. We cannot view local comparative judgements in isolation. (shrink)
