This volume explores the later life and thought of Charles S. Peirce, a fifteen-year period that spans from 1900 until his death in 1914. It is the first volume devoted to this period of Peirce’s philosophical work.

Peirce moved to the house he named Arisbe in Milford, Pennsylvania in 1898. Here he lived in relative isolation and continued to work on his scientific and semiotic philosophy. Peirce developed a modern logic that was influenced by changes he saw in the interdisciplinary study of science and technology, transforming his Pragmatism into his Pragmaticism. This action regarding Pragmaticism was a reaction against the downfall of deductive logic, and led Peirce to believe in the vagueness (“would-be”) of logical realism in deduction and later abduction. In Peirce’s later phase, he situated the “new” mathematics as a labyrinth of semiotic signs through which the quasi-mind of the logician could find a specialized sense to intuit the evolutionary semiosis of reality. The chapters in this volume examine all major dimensions of his thought during this period.

Late Peirce will appeal to scholars and graduate students interested in Peirce, American philosophy, pragmatism, logic, and semiotics.
