In this book, Nahum Brown not only offers a focused, thorough and unique explication of one of the most notoriously difficult chapters of Hegel's Greater Logic, but along the way develops provocative connections between Hegel's account of modality and the work of thinkers as diverse as Leibniz, Saussure and Agamben. The results will be as interesting to scholars who have long debated the intricacies of these pages, as they will be helpful to those working through Hegel's masterpiece for the first time.
