'The unique selling point of this thoughtful and well-written book is the range of material covered - Browning writes with authority on Kant, Hegel and Marx, on modern cosmopolitans such as Held, Giddens and Sassen, on radical theorists such as Hardt and Negri and public intellectuals such as Monbiot and Klein. His central thesis, that the first group of thinkers, the giants of modernity, have more to offer to their modern successors than the latter are often prepared to acknowledge, is entirely convincing.' - Professor Chris Brown, Professor of International Relations, London School of Economics and Politics, UK
