Abstract

In this paper I will address the specifics of Peirce’s concept of qualia. Peirce is the first philosopher to ever use the term qualia as philosophical, but his understanding of it differs considerably from the contemporary philosophy of mind. There are certain tendencies to present Peirce in this regard as a forerunner of contemporary debates. Although such an interpretation is not unfounded, I believe that it does not do full justice to the significance of the concept for Peirce’s thought. I will try to elucidate its importance with an adequate web of synonyms, that is, the other important concepts in Peirce’s philosophy. The main idea of the paper is that Peirce’s concept of qualia is not a technical term meant to tackle a finite group of problems within an already accepted ontology, but one of the concepts that Peirce uses to build his ontology.
