The article explores Charles S. Peirce's early view of the relation between cognition and being by examining his essays from 1868 to 1869. Published in the "Journal of Speculative Philosophy," these essays explain Peirce's objections to the strong classical version of foundationalism as well as his criticism of Descartes' method and epistemological individualism. It is the author's opinion that Peirce's essays present an isomorphic relation between cognition and being that is consistent with weak semiotic foundationalism. The author proposes a form of realism through a transcendental approach.
