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 alternative to Kantian philosophy, and ending with the first sustained and systematic presentation of his evolutionary metaphysics in the Monist Metaphysical Series of 1891-1893.
