The Peirce family in philosophy

The Peirce family in philosophy primarily refers to Charles Sanders Peirce (1839–1914), a pioneering American logician and thinker. He developed pragmatism, emphasizing that the meaning of ideas lies in their practical effects. Peirce also contributed to semiotics—the study of signs and symbols—and logic, shaping modern scientific reasoning. His work influenced various philosophical fields, including epistemology and metaphysics. While often called the “Peirce family,” the focus is mainly on Charles's groundbreaking ideas that continue to impact philosophy, science, and logic today.
