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. Charles S. Peirce: The Essential Writings is a comprehensive collection of the philosopher's writings including: "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."
