Political philosophers have recently begun to take seriously methodological questions concerning what a theoretical examination of political ideals is suppose to accomplish and how effective theorising in ideal theory is in securing those aims. Andrew Mason and G.A. Cohen, for example, believe that the fundamental principles of justice are logically independent of issues of feasibility and questions about human nature. Their position contrasts sharply with political theorists like John Dunn and Joseph Carens who believe that normative theorising must be integrated (...) with an appreciation of the empirical realities of one’s society. Rather than bracket questions of feasibility and human nature, empirically-oriented political theorists believe that real, non- ideal considerations must be taken seriously when deriving normative theories of justice.1 And some justice-theorists, most notably John Rawls, attempt to.

This paper contrasts universalist approaches to justice with contextualist approaches. Universalists hold that basic principles of justice are invariant — they apply in every circumstance in which questions of justice arise. Contextualists hold that different principles apply in different contexts, and that there is no underlying master principle that applies in all. The paper argues that universalists cannot explain why so many different theories of justice have been put forward, nor why there is so much diversity in the judgements that (...) ordinary people make. Several strategies open to universalists are considered and found to be wanting. Contextualism is defended against the charge that it cannot explain why contextually specific principles are all principles of justice, the charge that it can offer no practical guidance when principles conflict, and the charge that it inevitably collapses into a form of conventionalism. Key Words: justice • universalism • contextualism • conventionalism • Rawls • Walzer. (shrink)
