The late Susan Moller Okin was a leading political theorist whose scholarship integrated political philosophy and issues of gender, the family, and culture. Okin argued that liberalism, properly understood as a theory opposed to social hierarchies and supportive of individual freedom andequality, provided the tools for criticizing the substantial and systematic inequalities between men and women. Her thought was deeply informed by a feminist view that theories of justice must apply equally to women as men, and she was deeply engaged in showing how many past and present politicaltheories failed to do this. She sought to rehabilitate political theories--particularly that of liberal egalitarianism, in such a way as to accommodate the equality of the sexes, and with an eye toward improving the condition of women and families in a world of massive gender inequalities. In herlifetime Okin was widely respected as a scholar whose engagement went well beyond the world of theory, and her premature death in 2004 was considered by many a major blow to progressive political thought and women's interests around the world.This volume stems from a conference on Okin, and contains articles by some of the top feminist and political philosophers working today. They are organized around a set of themes central to Okin's work, namely liberal theory, gender and the family, feminist and cultural differences, and globaljustice. Included are major figures such as Joshua Cohen, David Miller, Cass Sunstein, Alison Jaggar, and Iris Marion Young, among others. Their aim is not to celebrate Okin's work, but to constructively engage with it and further its goals.
