This is a thought-provoking book, and is a useful addition to the textbook literature on this subject. --MAA Reviews Linnebo's slender volume is an admirable addition to the many existing books on the philosophy of mathematics. It is clear, concise, and well written. . . . All in all, this is an excellent introduction to the philosophy of mathematics and should be seriously considered by any individual interested in the subject. --Choice This book provides a nice lay of the land for anyone interested in contemporary philosophy of mathematics. ---Gregory Lavers, Philosophy Mathematica [This book] is very, very good. Superbly clear, concise, well organised, it gives not only a very accessible introduction but also takes the reader all the way to the cutting edge of what philosophers are doing in the philosophy of mathematics. Above all, Linnebo writes as a fully engaged philosopher and makes his preferred choice of philosophical position clear. But this is no mere polemic: I felt he clearly and forcefully presents the strengths and weaknesses of all the philosophical positions he discusses. ---Henri Laurie, Mathemafrica This is an excellent introduction to the philosophy of mathematics, with clear and careful coverage of both traditional topics and cutting-edge contemporary debates. --Roy T. Cook, University of Minnesota This is a good introduction to the philosophy of mathematics--clear and concise, and with original observations and a coherent point of view. --John P. Burgess, Princeton University
