Hare, Catherine Mackinnon, David Miller, Philippe Van Parijs, Susan Okin, Robert Nozick, John Rawls, John Roemer, Michael Sandel, Charles Taylor, Michael Walzer and Iris Young. Extended guides to further reading have been added at the end of each chapter, listing the most important books and articles on each school of thought, as well as relevant journals and websites. Covering some of the most advanced contemporary thinking, Will Kymlicka writes in an engaging, accessible and non-technical way to ensure the book is suitable for readers approaching these concepts for the first time.
