Most philosophers of art assume that there are three categories with regard to arthood, namely ‘art’, ‘artful’ and ‘non-art’ and that, therefore, a definition must be able to account for ‘artful items’, also called ‘borderline cases of art’. This article, however, defends the thesis that, since there is no agreement over which items fall under the category ‘artful’, the ability to account for borderline cases of art should not be used as a criterion for evaluating definitions of art. The defended (...) thesis is important, not merely because it reveals that virtually all alleged descriptive definitions of art have strong recommendatory consequences, but also because the thesis has implications for the artefacts that are considered to be borderline cases of art.
