Abstract

In this paper I synthesize a unified system out of Peirce's life work, and name it Peirce's Evolutionary Pragmatic Idealism. Peirce developed this philosophy in four stages: His 1868–69 theory that cognition is a continuous and infinite social semiotic process, in which Man is a sign. His Popular Science Monthly pragmatism and frequency theory of probabilistic induction. His 1891–93 cosmic evolutionism of Tychism, Synechism, and Agapism. Pragmaticism: The doctrine of real potentialities, and Peirce's pragmatic program for developing concrete reasonableness. Peirce's evolutionary conception of the cosmos is pantheistic, and he constructed it to reconcile religion with Darwinian evolution
