"This book presents the results of a genuine breakthrough in our understanding of the development of analytic philosophy in the twentieth century: the discovery by Greg Frost-Arnold of Carnap's notes recording extensive discussions with Tarski and Quine in 1940-41. Frost-Arnold's very careful and illuminating analysis of these discussions will be of great interest to all students of the analytic tradition." -MICHAEL FRIEDMAN, Stanford university "In 1940-41 Carnap, Tarski, and Quine met at Harvard to discuss fundamental issues. Thanks to this book we can now attend those discussions as well. Frost-Arnold goes beyond the recorded word to reconstruct in vivid terms the nuanced ideas of these three philosophic giants and, in addition, to tie those ideas to philosophic discussions that are still going on today. The book is a major achievement." -RICHARD CREATH, Arizona State University "In the 1980s a generation of eminent scholars pioneered the study of the history of analytic philosophy. In the last two decades, a younger generation of scholars has pushed the project forward by tapping the archives of the key thinkers in the analytic tradition. Of the many findings that have resulted from these efforts, the most exciting is arguably the discovery of the Carnap notes, amounting to more than eighty typescript pages, describing the conversations that took place at Harvard, in 1940-1941, between Carnap, Quine, and Tarski. During that year, these three giants of analytic philosophy had regular meetings discussing, among other things, the problem of the analytic/synthetic distinction and the prospects for a nominalist foundation of mathematics and science. In this superb book, Greg Frost-Arnold provides a rich and subtle discussion of these notes. In addition, he has put us in his debt by accurately editing and translating the notes. As in the case of the best people working in the history of analytic philosophy, the engagement with history is for Frost-Arnold, at the same time, an engagement with our own situation. And he is successful in bringing the material contained in the Carnap notes to life by showing their relevance to contemporary discussions in philosophy of mathematics and logic." -PAOLO MANCOSU, UC Berkeley "Carnap, Tarski and Quine met together in 1940-1941 at Harvard to discuss their views on the nature of language and the differences between logic, mathematics and science. In this remarkable book Greg Frost-Arnold presents Carnap's extensive notes on these meetings. Frost-Arnold also includes an elegant translation and a detailed commentary that sets the notes in their philosophical context and demonstrates their importance for many central debates about the history of analytic philosophy. This book marks a decisive advance in our understanding of the philosophical views of Carnap, Tarski and Quine, and is essential reading for all who work on these topics." -CHRISTOPHER PINCOCK, The Ohio State University "Some of the most influential positions in analytical philosophy resulted from debates that found only partial reflection in the publications of their protagonists. On the basis of archival sources Greg Frost-Arnold reconstructs and analyzes, in unprecedented detail and with good judgment, one of these seminal debates, providing many valuable insights into the development of ontology and philosophy of language at mid-century and into the long-lasting debate about analyticity." -THOMAS UEBEL, University of Manchester
