Charles Sanders Peirce is usually introduced through fragments: a slogan about pragmatism, a diagram of signs, a footnote in someone else’s system. This book does the opposite. It reconstructs Peirce as a working philosopher whose ideas about inquiry, meaning, truth, logic, science, and reality form a coherent—if deliberately unfinished—intellectual project. The book begins with Peirce’s life: a prodigy raised on mathematics, a brilliant logician sidelined by institutions, a scientist whose experience with measurement and error shaped everything he thought about knowledge. From there, it explains his core ideas in direct language: why certainty is a mistake, why skepticism is lazy, why inquiry is social and historical, and why reality matters even when all access to it is mediated. Peirce’s pragmatism is treated carefully—not as a philosophy of “what works,” but as a method for clarifying meaning without moralizing it. His logic is explained as a theory of reasoning in practice, including deduction, induction, and his most original contribution: abduction, or disciplined hypothesis-formation. His semiotics is unpacked without mysticism, showing why signs are unavoidable, why meaning is triadic, and why language is only one sign system among many. The book also tackles Peirce’s metaphysics head-on: continuity, chance, habit, and the infamous doctrine of “evolutionary love.” Nothing is protected from criticism. Where Peirce overreaches, it is said plainly. Where later thinkers misunderstood or diluted his ideas, the damage is traced carefully. Throughout, Peirce is placed in conversation with other major figures—Kant, positivists, postmodernists, philosophers of science, semioticians, and contemporary thinkers in cognitive science, AI, and complexity theory—showing both what he anticipated and where he stubbornly refuses to fit. This is not a simplified Peirce. It is Peirce without unnecessary obscurity.
