Promotional Information

A first-rate contribution to the history and philosophy of logic, this is scholarship at its best. It is, to my knowledge, the first book in the history of logic that focuses completely on a single result. Very original in approach and conception, it goes against the grain of much recent scholarship. Given the complexity of the subject, Badesa could not have done a better job of being clear and making the presentation accessible. -- Paolo Mancosu, University of California, Berkeley The Birth of Model Theory represents a long overdue, in-depth analysis and exposition of one of the most important results in mathematical logic. There are hardly any informed, sustained treatments of Lowenheim's work to be found in the literature. This well-written book should fill this gap. -- Richard Zach, University of Calgary This book will be extremely useful to those seeking to make sense of Lowenheim's work and those seeking to put it into its historical context. Calixto Badesa draws well-supported conclusions that contradict the entire modern body of scholarship on the topic. -- Shaughan Lavine, University of Arizona
