In this article, I argue that the fact of reasonable pluralism (FRP) – a famous Rawlsian assumption about the intellectual demographics of liberal democracies – is not as self-evident as is sometimes thought. The problem with the FRP is that in Political Liberalism Rawls is treating the freedoms and burdens story as being sufficient – in itself – to explain the demographics of reasonable pluralism. The inadequacy of the freedoms and burdens story is an indication that the FRP is empirically underdetermined as a way of glossing the belief demographics of liberal democracies. And it is a reason to wonder whether pluralism is as permanent as Rawls thinks. But worldview disagreements are not necessarily so incorrigible. In response to the FRP, it can be asserted that there is nothing that is inherent in the idea of a liberal democracy to preclude the choice by the citizens of a common worldview.
