Kevin Vallier has recently argued that the ideals of public justification and public deliberation should be separated. The link between the two, Vallier suggests, has been assumed without being properly defended. Once examined, the connection falls apart. In this paper, I argue that there is, in fact, a clear and convincing story available for why the two ideals should be treated as mutually reinforcing. Drawing on recent empirical evidence, I argue that the deliberative behaviour of citizens can have a clear (...) and positive impact on the behaviour and policy choices of public officials. (shrink)
