Charles Sanders Peirce: 55 Selected Philosophical Writings is a comprehensive collection of essential essays, lectures, and philosophical reflections by Charles Sanders Peirce, one of the most innovative and influential thinkers in modern philosophy. Bringing together fifty-five significant writings, this volume offers readers a broad introduction to Peirce’s groundbreaking ideas on pragmatism, logic, scientific inquiry, metaphysics, semiotics, and the philosophy of knowledge.Widely recognized as the founder of pragmatism, Peirce developed a philosophical method that evaluates ideas through their practical consequences and observable effects. His famous pragmatic maxim transformed modern philosophy by emphasizing the relationship between thought, experience, and action. Throughout these writings, Peirce investigates the nature of truth, belief, doubt, reasoning, and the scientific method, arguing that knowledge emerges through continuous inquiry and communal investigation rather than absolute certainty.The collection also highlights Peirce’s pioneering contributions to the theory of signs and symbols, establishing the foundations of modern semiotics. His reflections on language, meaning, perception, and interpretation profoundly influenced later developments in philosophy, linguistics, psychology, and communication theory. Combining rigorous analytical thought with intellectual imagination, Peirce’s work bridges science, logic, mathematics, and metaphysical speculation in a uniquely original way.Rich in philosophical depth and intellectual range, Charles Sanders Peirce: 55 Selected Philosophical Writings serves as both an accessible introduction and an invaluable reference for students, scholars, and general readers interested in the evolution of modern thought. This collection preserves the enduring legacy of a philosopher whose ideas continue to shape contemporary discussions of knowledge, meaning, truth, and scientific reasoning.
