Public reason and the normativity of the reasonable

Abstract

The main purpose of the paper is to contribute to reconstructing the kind of normativity underlying Rawls’s notion of public reason and of the reasonable. The implicit target is the somewhat popular view according to which the transition from the framework of A Theory of Justice to that of Political Liberalism would entail a loss of normativity. On the contrary, the related ideas of public reason and the reasonable are argued to presuppose a notion of normativity – linked with judgment – far more consistent with the premise of the fact of pluralism. After reconstructing Rawls’s notion of public reason, the two following problems are addressed: the problem of determining when allegedly shared truths, the building stones of public reason, are really such and, second, the problem of what it means for one reason to follow or proceed from a shared basis. In the context of such discussion three distinct meanings of the term ‘reasonable’ are identified, and the normatively more demanding one – the notion of some thesis or proposal being not just reasonable, but comparatively ‘more reasonable’ than another – is found to require that the reasonable be understood as the exemplary and, consequently, that we find ways to translate the Kantian doctrine of the exemplary yet universalist validity of aesthetic judgments into a non-aesthetic vocabulary.
