My aim in this paper is to propose a new categorization of a specific set of aesthetic concepts, using Sibley’s theory of the aesthetic concepts as a starting point. I discuss the status of aesthetic concepts connected with pleasure and the role of aesthetic pleasure. I examine Sibley’s theory and the importance of its results for the conceptual art. Then, I compare Sibley’s theory and Kant’s theory specifically on the theme of judgment, universal agreement and pleasure. I finally propose to (...) look at these theories as complementary (they deal with the same problems but Sibley takes an objective position, since his main focus is the object and its properties, while in Kant’s theory the focus is on the subject) since they achieve important results for the theory of aesthetic concepts, both from the perspective of the subject and from the perspective of the object.
