Impartiality and Liberal Neutrality

It is a commonplace that in many societies people adhere to profoundly different conceptions of the good. Given this we need to know what political principles are appropriate. How can we treat people who are committed to different accounts of the good with fairness? One recent answer to this pressing question is given by Brian Barry in his important work Justice as Impartiality. This book, of course, contains much more than this. It includes a powerful and incisive discussion of several accounts of distributive justice (‘justice as mutual advantage’ and ‘justice as reciprocity’), a critique of other attempts to defend liberal neutrality and a rebuttal of those who are critical of the ideal of impartiality. In this paper I wish, however, to focus on Barry's defence of liberal neutrality. The paper falls into three parts. Section I outlines the thesis that Barry wants to defend and gives a brief sketch of the argument he employs to defend it. Barry's argument makes two claims – what I have termed the Sceptical Thesis and the Agreement Thesis. Section II therefore critically assesses Barry's defence of the sceptical thesis and Section III examines the agreement thesis.
