In his Tanner Lecture of 1979 called ‘Equality of What?’ Amartya Sen asked what metric egalitarians should use to establish the extent to which their ideal is realized in a given society. What aspect of a person’s condition should count in a fundamental way for egalitarians, and not merely as cause of or evidence of or proxy for what they regard as fundamental?

Though the revised edition of A Theory of Justice, published in 1999, is the definitive statement of Rawls's view, so much of the extensive literature on Rawls's theory refers to the first edition. This reissue makes the first edition once again available for scholars and serious students of Rawls's work.

I apply an agent-based virtue ethics to issues in environmental philosophy regarding our treatment of complex inorganic systems. I consider the ethics of terraforming: hypothetical planetary engineering on a vast scale which is aimed at producing habitable environments on otherwise “hostile” planets. I argue that the undertaking of such a project demonstrates at least two serious defects of moral character: an aesthetic insensitivity and the sin of hubris. Trying to change whole planets to suit our ends is arrogant vandalism. I (...) maintain that these descriptions of character are coherent and important ethical concepts. Finally, I demonstrate how the arguments developed in opposition to terraforming, a somewhat farfetched example, can be used in cases closer to home to provide arguments against our use of recombinantDNA technologies and against the construction of tourist developments in wilderness areas.

David Miller explores and develops Michael Walzer's notion of complex equality as a way of bringing together the potentially conflicting ideas of distributive justice and social equality. He examines the empirical plausibility of the notion of complex equality and argues that Walzer's theory of the spheres of justice allows the construction of an understanding of distributive justice and social equality that is different from, and superior to, mainstream political philosophy.
