This book is both shorter and more comprehensive than any of Quine's other six since Word and Object. But let this description raise no fears that it must stretch itself too thin, at least for veteran students of his major philosophical project, “to examine the evidential support of science” (p. 2). For with less detail in focus, the structural elements of that project stand revealed as never before. Improvements in presentation, as Quine sees them, help here. And veterans can learn of certain changes, notable if not huge, in various Quinean views. For besides summing up and explaining, Pursuit of Truth moves on.
