(The Art of Art. Meta-aesthetics). Stuttgart: Belser Verlag, 1990. xxxvii + 274 pp.

Based on research in aesthetics, art history and theory, semiotics, and logic, the book discusses the self-referential quality of artworks. In order to understand if the verbal language humans use to describe art is appropriate to the condition of artworks, and what role this language has in the world of art, the interpreter of art must operate on categories defined at a meta-level in respect to the object level of art production as such.
