A convenient two-volume reader's edition makes accessible to students and scholars the most important philosophical papers of the brilliant American thinker Charles Sanders Peirce. Volume 1 presents twenty-five key texts, chronologically arranged, beginning with Peirce's On a New List of Categories of 1867, a highly regarded alternative to Kantian philosophy, and ending with the first sustained and systematic presentation of his evolutionary metaphysics in the Monist Metaphysical Series of 1891ETH1893. The book features a clear introduction and informative headnotes to help readers grasp the nature and significance of Peirce's thought system. Bringing together all the writings needed for the study of Peirce's systematic philosophy and its development, Volume 1 is ideal for classroom use. Volume 2, covering the period from 1894 until Peirce's death in 1914, will highlight the development of his system of signs and his mature pragmatism.
