While Peirce is a seminal figure for contemporary semiotic philosophers, it is axiomatic of a fully semiotic perspective that no philosopher or philosophy (semiotics included) can provide any final answer, as signs are always interpreted and the context of interpretation always varies. Semiosis is evolutionary: it may or may not be construed as progressive but it cannot be static. While Peirce offers a way out of the mind‐body divide that both permeates and separates classical rationalism and empiricism, he himself is read in this article as closer to the rationalist tradition exemplified by Kant and Hegel that he critiques than to either thoroughgoing empiricism or post‐Nietzschean relativism. From a contemporary perspective, Peirce thus falls short of qualifying as a fully semiotic thinker, notwithstanding his key role in the development of semiotic philosophy.
