Anti-perfectionism and Rawlsian Liberalism

This article examines the justifications of anti-perfectionism given by John Rawls in his recent work Political Liberalism. Rawls, I argue, gives one major argument in defence of anti-perfectionism (what I shall call the 'reasonableness among free and equal persons' argument) and two subsidiary arguments (what I shall call the 'social unity' argument and the 'stability' argument). None of these arguments, I claim, are persuasive. Rawls's most recent justification of anti-perfectionism is therefore unsuccessful.
