This 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 2 presents twenty-nine pivotal texts, beginning with "Immortality in the Light of Synechism", in which Peirce proposes synechism, the tendency to regard everything as continuous, as a key advance over the three popular 'isms' materialism, idealism, and dualism, and ending with Peirce's late and unfinished investigations of the relative merits of different kinds of reasoning.Included are selections from Peirce's Harvard lectures on pragmatism, Lowell lectures on logic, and 'Syllabus of Certain Topics of Logic,' all of 1903. During his later years Peirce worked unremittingly to integrate new insights and discoveries into his general system of philosophy, and to make his major doctrines fully coherent within that system. This volume gives the first comprehensive presentation of Peirce's mature philosophy and is required reading for students who want to appreciate the breadth of learning and wisdom of America's greatest pragmatist.
