Axiomatics : mathematical thought and high modernism The first history of postwar mathematics offering a new interpretation of the rise of abstraction and axiomatics in the twentieth century. Why did abstraction dominate American art social science and natural science in the mid twentieth century Why despite opposition did abstraction and theoretical knowledge flourish across a diverse set of intellectual pursuits during the Cold War In recovering the centrality of abstraction across a range of modernist projects in the United States Alma Steingart brings mathematics back into the conversation about midcentury American intellectual thought. The expansion of mathematics in the aftermath of World War II she demonstrates was characterized by two opposing tendencies: research in pure mathematics became increasingly abstract and rarified while research in applied mathematics and mathematical applications grew in prominence as new fields like operations research and game theory brought mathematical knowledge to bear on more domains of knowledge. Both were predicated on the same abstractionist conception of mathematics and were rooted in the same approach: modern axiomatics. For American mathematicians the humanities and the sciences did not compete with one another but instead were two complementary sides of the same epistemological commitment. Steingart further reveals how this mathematical epistemology influenced the sciences and humanities particularly the postwar social sciences. As mathematics changed so did the meaning of mathematization. Axiomatics focuses on American mathematicians during a transformative time following a series of controversies among mathematicians about the nature of mathematics as a field of study and as a body of knowledge. The ensuing debates offer a window onto the postwar development of mathematics band Cold War epistemology writ large. As Steingart’s history ably demonstrates mathematics is the social activity in which styles of truth—here abstraction—become synonymous with ways of knowing
