Abstract

The de nition of qualia — a contribution to logical philosophy In my article, I propose an abstract de nition of a quale, which (generally speaking) identi es qualia with sets belonging to certain relational structures. I maintain that my de nition, by not taking advantage of psychological terms, makes the notion of a quale more understandable and the existence of qualia themselves less disputable than is commonly supposed. In addition, I brie y discuss the traditional concept of a quale.
