Physicist, mathematician, and logician Charles S. Peirce (1839-1914) was America's first internationally recognized philosopher, the man who created the concept of "pragmatism," popularized by William James. This comprehensive collection of the philosopher's writings includes "Questions Concerning Certain Faculties Claimed for Man" (1868), which outlines his theory of knowledge; a review of the works of George Berkeley; papers from between 1877 and 1905 developing the ground of pragmatism and Peirce's theory of scientific inquiry; his basic concept of metaphysics (1891-93); and the important 1902 articles in Baldwin's dictionary on his later pragmatism (or pragmaticism), uniformity, and synechism. Also included are Peirce's well-known essays: "The Fixation of Belief," and "How to Make Our Ideas Clear."
