This is an excellent book for those who would like to know how can we continue to do politics in our present post-modern world. In this book, Laclau continues his elaboration on how do to politics in face of fragmented social struggles. Laclau's essays on universalism and particularism offers an important contribution to understand the various groups that struggle for identification of their rights. There is an introduction of linguistic term of `empty signifier', that plays an important role to the world of politics. He also includes a critical assessment of Rorty's notion of Liberalism and comments on Derrida's work. Although the book is rather a short, its topic makes it quite dense that can take some time to go through.
