"Rawls’s analysis of fairness, justice, institutions and behaviour has illuminated our understanding of justice very profoundly and has played – and is still playing – a hugely constructive part in the development of the theory of justice. But we cannot make the Rawlsian mode of thinking on justice into an intellectual ‘stand-still’. We have to benefit from the richness of the ideas we have got from Rawls – and then move on, rather than taking a ‘vacation’. We do need ‘justitia’, not ‘justitium’."
