Volumes I-VIII of the Collected Papers of Charles Sanders Peirce are being reissued in response to a growing interest in Peirce's thought--a development that was prophesied by John Dewey when he reviewed the first volume of these papers on their appearance in 1931. Writing in "The New Republic," Mr. Dewey said, "Nothing much will happen in philosophy as long as a main object among philosophers is defense of some formulated historical position. I do not know of any other thinker more calculated than Peirce to give emanipation from the intellectual fortifications of the past and to arouse a fresh imagination." Originally published as eight separate volumes, the Peirce papers appear in the new Belknap Press edition in four handsome books of two volumes each. The content is identical with that of the original edition: Volume I, "Principals of Philosophy"; Volume II, "Elements of Logic"; Volumes III, "Exact Logic"; Volumes IV, "The Simplest Mathematics"; Volumes V, "Pragmatism and Pragmaticism"; Volume VI, "Scientific Metaphysics"; Volume VII, "Science and Philosophy"; Volume VIII, "Reviews, Correspondence, and Bibliography."
