Artworld Metaphysics turns a critical eye upon aspects of the artworld, and articulates some of the problems, principles, and norms implicit in the actual practices of artistic creation, interpretation, evaluation, and commodification. Aesthetic theory is treated as descriptive and explanatory, rather than normative: a theory that relates to artworld realities as a semantic theory relates to the fragments of natural language it seeks to describe. Robert
Kraut examines emotional expression, correct interpretation and objectivity in the context of artworld practice, the relevance of jazz to aesthetic theory, and the goals of ontology (artworld and otherwise). He also considers the relation between art and language, the confusions of postmodern relativism, and
the relation between artistic/critical practice and aesthetic theory.
