Charles Sanders Peirce

Charles Sanders Peirce was an American philosopher, logician, mathematician, and scientist whose work helped establish pragmatism and modern semiotic theory. He also pursued scientific research for 32 years with the U.S. Coast and Geodetic Survey, bringing empirical methods to his studies of logic, inquiry, and belief. His writings ranged across mathematics, the physical sciences, language, psychology, and metaphysics, making him one of the most wide-ranging thinkers in American intellectual history.
