"The book is an impressive achievement, and it will be an important contribution to the literature on Frege, Russell, Wittgenstein, Ramsey, and the history of early analytic philosophy. I thoroughly enjoyed reading it and learned a lot from it. It is not only a state-of-the-art contribution to scholarship but will also be a valuable textbook for courses on the history of early analytic philosophy, or on the work of one or more of the four philosophers discussed."--David G. Stern, University of Iowa, USA"This book is a significant contribution to studies in the history of analytic philosophy and will benefit upper-level undergraduates studying this material for the first time, as well as active researchers in the area."--James Levine, Trinity College Dublin, Ireland
