He is considered to be the founder of pragmatism and the father of modern semiotics. In recent decades, his thought has enjoyed renewed appreciation. At present, he is widely regarded as an innovator in many fields, especially the methodology of research and the philosophy of science.

Charles Sanders Peirce was born in Cambridge, Massachusetts, the son of Sarah and Benjamin Peirce. His father was a professor of astronomy and mathematics at Harvard University. Though the young Peirce received a graduate degree in chemistry from Harvard, he never succeeded in obtaining a tenured academic position. Peirce's academic ambitions were frustrated by his difficult (perhaps manic-depressive) personality and by the scandal surrounding his divorce from Harriet Melusina Fay and his marriage to Juliette Froissy which immediately followed. He made a career as a scientist for the United States Coast Survey (1859–1891), working especially in geodesy and in gravimetry, refining the practice of pendulum determinations. From 1879 until 1884, he was also a part-time lecturer in Logic at Johns Hopkins University. In 1887, Peirce moved with his second wife to Milford, Pennsylvania, where, after 26 years of prolific writing, he died of cancer. He had no children.
Peirce published two books, Photometric Researches (1878) and Studies in Logic (1883), and a large number of papers in journals in widely differing areas. His manuscripts, a great many of which remain unpublished, run to some 10,000 pages. In the years 1931 to 1958, a selection of his writings was arranged thematically and published in eight volumes as the Collected Papers of Charles Sanders Peirce. Since 1982, a number of volumes have been published as part of a Chronological Edition, which will eventually consist of thirty volumes.
Founder of pragmatism (according to William James), and unlike some later pragmatists such as James and John Dewey, Peirce conceived of pragmatism primarily as a method for the clarification of ideas, which involved applying the methods of science to philosophical issues. Pragmatism has been regarded as a distinctively American philosophy.
Also considered to be the father of modern semiotics (the science of signs), Peirce defines semiosis as "an action, or influence, which is, or involves, a cooperation of three subjects, such as a sign, its object, and its interpretant ..." ('Pragmatism', Essential Peirce 2:413, 2:411, 1907). Peirce revised his view of semiosis throughout his career, beginning with this triadic relationship and ending with a system consisting of 59,049 possible elements and relationships. One reason for this high figure is that Peirce allowed each interpretant to act as a sign, creating a new signifying relationship.
Moreover, his often pioneering work is relevant to many disciplines, such as astronomy, metrology, geodesy, mathematics, logic, philosophy, the theory and history of science, linguistics, econometrics, and psychology. His work and his views on these subjects have become the subject of renewed interest and lavish praise. This revival is inspired not only by Peirce's intelligent anticipations of recent scientific developments but also, and especially, by his demonstration of how philosophy can be applied responsibly to human problems. Bertrand Russell opined, "Beyond doubt...he was one of the most original minds of the later nineteenth century, and certainly the greatest American thinker ever." Karl Popper viewed him as "one of the greatest philosophers of all times."
Abductive reasoning (abduction)
In some ways, Peirce was a systematic philosopher in the traditional sense of the word. But his work also deals with modern problems of science, truth, and knowledge, starting from his own personal experience as a logician and experimental researcher who labored within an international community of scientists and thinkers. Peirce made relevant contributions to deductive logic, but he was primarily interested in the logic of science and specifically in what he called abduction (as opposed to deduction and induction). Abduction is the process whereby a hypothesis is generated, so that surprising facts may be explained. "There is a more familiar name for it than abduction," Peirce wrote, "for it is neither more nor less than guessing." Indeed, Peirce considered abduction to be at the heart not only of scientific research but of all ordinary human activities as well. His pragmatism may be understood as a method of sorting out conceptual confusions by relating the meaning of concepts to practical consequences. Emphatically, this theory bears no resemblance to the vulgar notion of pragmatism, which connotes such things as the ruthless search for profit or political convenience.
Peirce also established various other facets of modern logic:
- proved the operation called logical nand and the operation called logical nor are each individually sufficient to derive all other Boolean operations. (See also De Morgan's Laws)
- defined the standard functional notation for first-order predicate logic.
- developed the existential graph, a visual notation for predicate calculus and the basis of the conceptual graph of John F. Sowa.
- described the use of electrical switches as logic gates more than 60 years before Claude Shannon.
