“The erudition and scope of Redding’s new book are staggering. This is a very fine book on the history of ancient logic and mathematics and its modern German reception, and it is also a major contribution to Hegel studies and philosophy. We finally have a clear and compelling answer to the question, What did Hegel actually think logic was? Redding has shown us the deep philosophical importance of that answer.”

“Conceptual Harmonies powerfully challenges a long-standing barrier to a full appreciation of Hegel’s logic: the assumption that, given his trenchant critique of all ‘formalisms,’ Hegel’s logic is in no way mathematical. With his characteristic erudition and insight, Redding guides readers through a history of logic and mathematics from Plato to the twentieth century, toward an entirely new understanding of Hegelian logic. Redding’s latest is a must-read for anyone interested in Hegel and the history of logic, proving once again that Redding is one of the most original, rigorous, and historically sensitive interpreters of Hegel writing in any language.”

“In Conceptual Harmonies, Redding makes a breathtakingly original case for a new understanding of Hegel’s Logic. Expanding the examination of Hegel’s sources well beyond the standard Aristotelian and Kantian texts, Redding rewrites the history of logic to show that Hegel anticipated many developments in the mid-nineteenth century and beyond. This is a major achievement that opens up a new line of research into Hegel’s though
