"This is an important book. It sets a standard for discussions of early analytic philosophy, sets the problems for the emerging subject of the history of Positivism and it makes a strong claim for the place of the 'semantic' tradition as an equal to Kantianism and Positivism in 19th-century philosophy and as the direct ancestory of Analytic philosophy. Coffa demonstrates the richness of the views of the Vienna Circle, and a continuity with earlier neo-Kantian philosophy, that should put to rest the caricature of Positivists as attacking a tradition they did not understand. This is all done with carefully crafted and argued discussions of the relevant philosophers, and presented with a lively, if searing, wit." Canadian Philosophical Reviews

"Alberto Coffa is an intellectual pioneer. His book is the first comprehensive treatment of the development of logical positivism that is rigorous and sophisticated from both an historical and a technical point of view. It will constitute an indispensable basis for all future research in the area." Michael Friedman, University of Illinois at Chicago
"The late Alberto Coffa wrote a magnificent book. According to its title, it is a history of the semantic tradition from Kant to Carnap. but it is really much more. It is also a history of the ontological problems that shaped the analytic philosophy of the 20th century. It is a history of the attempts to refute Kant's claim that there are synthetic a priori judgments. And most of all it is a careful analysis of the philosophical background of the logical positivists of the Vienna Circle." International Studies in Philosophy
