In line with the emerging field of philosophy of mathematical practice, this book pushes the philosophy of mathematics away from questions about the reality and truth of mathematical entities and statements and toward a focus on what mathematicians actually do—and how that evolves and changes over time. How do new mathematical entities come to be? What internal, natural, cognitive, and social constraints shape mathematical cultures? How do mathematical signs form and reform their meanings? How can we model the cognitive processes at play in mathematical evolution? And how does mathematics tie together ideas, reality, and applications?
Roi Wagner uniquely combines philosophical, historical, and cognitive studies to paint a fully rounded image of mathematics not as an absolute ideal but as a human endeavor that takes shape in specific social and institutional contexts. The book builds on ancient, medieval, and modern case studies to confront philosophical reconstructions and cutting-edge cognitive theories. It focuses on the contingent semiotic and interpretive dimensions of mathematical practice, rather than on mathematics' claim to universal or fundamental truths, in order to explore not only what mathematics is, but also what it could be. Along the way, Wagner challenges conventional views that mathematical signs represent fixed, ideal entities; that mathematical cognition is a rigid transfer of inferences between formal domains; and that mathematics’ exceptional consensus is due to the subject’s underlying reality.
The result is a revisionist account of mathematical philosophy that will interest mathematicians, philosophers, and historians of science alike.

"[Making and Breaking Mathematical Sense] offers a substantial and interesting treatment of issues in the philosophy of mathematical practice."--Calvin Jongsma, MAA Reviews
"Mathematicians and philosophers should find this excellent book accessible and stimulating. As a mathematician, I was pleasantly surprised that some of Deleuze's philosophy could be made not just comprehensible but compelling. Among the new mathematical material, the book's account of Bombelli and the cubic equation was particularly impressive. And the story of the emergence of negative and imaginary numbers has never been told with such subtlety and clarity."--John Stillwell, University of San Francisco
"Most contemporary analytic theories give pat characterizations of the nature of mathematics. But Wagner argues that the complexity and richness of the subject resist such formulas. Accessible to philosophers and philosophically curious mathematicians, this is a fresh, interesting, and thought-provoking book."--Jeremy Avigad, Carnegie Mellon University
