Peirce, Charles Sanders

Charles Sanders Peirce (1839–1914) was an American philosopher, logician, and scientist known for developing foundational ideas in logic and semiotics—the study of signs and symbols. He pioneered the concept of pragmatism, emphasizing that the meaning of ideas is rooted in their practical effects. Peirce also made significant contributions to how we understand reasoning, scientific methods, and the way signs communicate meaning. His work influences philosophy, mathematics, linguistics, and cognitive science, making him a key figure in shaping modern thought about knowledge, language, and logic.
