Taking up three urgent problems of social justice neglected by current theories and thus harder to tackle in practical terms and everyday life, Martha Nussbaum seeks a theory of social justice that can guide us to a richer, more responsive approach to social cooperation. ,How can we extend the equal rights of citizenship--education, health care, political rights and liberties--to those with physical and mental disabilities? How can we extend justice and dignified life conditions to all citizens of the world? And how, finally, can we bring our treatment of nonhuman animals into our notions of social justice? Exploring the limitations of the social contract in these three areas, Nussbaum devises an alternative theory based on the idea of "capabilities." She helps us to think more clearly about the purposes of political cooperation and the nature of political principles--and to look to a future of greater justice for all. ,
