Working from Within is an impressive scholarly and philosophical achievement. Its exemplary use of archival sources to construct a richer, deeper account of the nature and development of Quine's naturalism sets a new standard in Quine scholarship. Everyone who wants to understand Quine's naturalism should read it.

Gary Ebbs, Notre Dame Philosophical Reviews

Verhaegh masterly combines a deeply informative and clear presentation of Quine's views with a detailed and revealing reconstruction of numerous archive materials [...] a real masterpiece of historical scholarship

Adam Tamas Tuboly, Metascience

Using the wealth of materials and letters found in the Quine archives at Houghton Library in Harvard, Sander Verhaegh has constructed a masterful account of Quine's philosophical development, one which is especially focused on the emergence of Quine's naturalism. He highlights the main problems Quine faced as his constructive view fell into place, some of these seemingly lost to history, while further defending novel interpretations of this development that challenge standard readings [...] Verhaegh has provided an authoritative guide to Quine's philosophical development, one which all students of Quine's naturalism will need to study

Robert Sinclair, British Journal for the History of Philosophy

This outstanding book combines a splendid overview of Quine's naturalism with a mastery of his archive. We get to see the ideas of Word and Object emerge and learn what mattered most to Quine in writing it. ... Verhaegh's book is indispensable.

Richard Creath, President's Professor of Philosophy, Arizona State University

A deeply informative and historically grounded guide to Quine's naturalism. By reconstructing the evolution of Quine's writing of Word and Object over a period of nearly twenty years (and providing a scholarly guide to the Quine archives), Verhaegh shows how Quine's numerous manuscripts and correspondence reveal the most important and difficult philosophical juncture points Quine had to face in writing his first major philosophical book. In the twists and turns of Quine's own struggles with articulating his philosophical thoughts, Verhaegh shows us much of the true depth, dynamism, and sophistication of Quine's thought.

Juliet Floyd, Professor of Philosophy, Boston University

This is an outstanding work. I agree with the main points, am grateful for them, and heartily applaud the sheer amount of work that has gone into it, philosophical as well as scholarly. I learned. Every Quine-scholar will have to read it and many students would be well-advised to read it also.
