Reducing Illation to Sign Relation: The Roots of Peirce’s General Theory of Signs

This article builds on Bellucci’s and Murphey’s accounts of Peirce’s early logic of signs by making a pair of contributions to the literature on Peirce’s reduction of illation to the sign relation. First, I reinvesti-gate the connection between the structure of inference and the representative relation, relying here on Peirce’s early accounts of sign inference from 1865 and 1866. Second, with the development of Peirce’s theory of inquiry in mind, I elucidate the implications of Peirce’s early view of sign inference. These contributions deepen our understanding of Fisch’s claim that the Illustrations series “is thought out within the framework of the doctrine of signs.”
