From Really Being to Being Represented

This essay attempts an overview of Peirce’s pragmaticist doctrine of the truth of propositions. Relying on his writings, I try to characterize his conception of the real and discuss the ways in which his peculiar scholastic metaphysics, opposing that of nominalists, is a central tenet of the pragmaticist view of truth which he strived to develop. Peirce conceived indeed real possibilities and real necessities to be just as real as actualities, those realities corresponding in nature to qualities (“firsts”), laws (“thirds”), and existents (“seconds”), respectively. More specifically, I detail the peculiar mode of being of each kind of real elements and show that all three categories must be recognized at once in true propositions. This led Peirce to conclude that if propositions are general signs indeed and, as such, along with terms and arguments, are necessarily dependent on mind, it does not in the least preclude those propositions to be about, nor true of, a real world – a position which actually constitutes a necessary prerequisite for any meaningful conception of scientific inquiry. I believe that a focus on such interrelations between Peirce’s categorial account of the real and Peirce’s pragmaticist conception of truth constitutes an ideal testament to the systematic nature of his thought, which is an aspect often deflated in unspecialized literatures
