Charles Sanders Peirce


Before Charles Sanders Peirce, only a few thinkers combined scientific and philosophical expertise, and not coincidentally they count among the most important philosophers of all time: Thomas Hobbes, René Descartes, and Immanuel Kant. Peirce belongs with this exclusive company. He inspired generations of pragmatists from William James and John Dewey to W.V. Quine and Hilary Putnam, and his work was developed into new areas of thought, including algebraic logic, process philosophy, process theology, semiotics, and symbolic interactionism. Read about Peirce's impact.
