Justice and Culture: Rawls, Sen, Nussbaum and O'Neill

Is it possible, in a multicultural world, to hold all societies to a common standard of decency that is both high enough to protect basic human interests, and yet not biased in the direction of particular cultural values? We examine the recent work of four liberals – John Rawls, Amartya Sen, Martha Nussbaum and Onora O'Neill – to see whether any of them has given a successful answer to this question. For Rawls, the decency standard is set by reference to an idea of basic human rights that we argue offers too little protection to members of non-liberal societies. Sen and Nussbaum both employ the idea of human capabilities, but in interestingly different ways: for Sen the problems are how to weight different capabilities, and how to decide which are basic, whereas for Nussbaum the difficulty is that her favoured list of capabilities depends on an appeal to autonomy that is unlikely to be acceptable to non-liberal cultures. O'Neill rejects a rights-based approach in favour of a neo-Kantian position that asks which principles of action people everywhere could consent to, but this also may be too weak in the face of cultural diversity. We conclude that liberals need to argue both for a minimum decency standard and for the full set of liberal rights as the best guarantors of that standard over time.
