"Above all, its comparative investigation is what makes Contesting the Global Order a distinctive contribution to Radical Political Economy. Not only is this a relatively uncommon undertaking in the field, it is also a challenging one. Comparative intellectual biographies require their authors to master the intellectual trajectories and outputs of their subjects, and then make the critical decision of choosing the right axes of comparison. Even more crucially, the actual substance of comparison has to be parsimoniously presented in order to be effective. Williams does a great job on all these scores." — E-International Relations"This is a thoroughly impressive first book by a young scholar … Highly recommended." — CHOICE"Williams's book offers a sustained analysis of two of the most significant contributors to twentieth-century radical political economy. In addition to learning about the specific features of their thought and getting a feel for the arc of their lives' work, one also encounters useful debates among radical anticapitalist thinkers over central political concepts." — Jane Anna Gordon, author of Statelessness and Contemporary Enslavement
