AbstractThis essay seeks to demonstrate that there are no compelling reasons to exclude non-Western artefacts from the domain of art. Any theory of art must therefore account for the universality of the concept of art. It cannot simply start from ‘our’ art traditions and extend these conceptions to other cultures, since this would imply cultural appropriation, nor can it resolve the matter simply by formulating separate criteria for non-Western art, since this would imply that there is no unity in the concept of art. At first sight, cluster theories of art seem capable of accounting for the universality of art since they (can) start from a broad cross-cultural range of artworks and nowhere seem to extend one conception of art to other conceptions. Yet cluster theories remain unsatisfactory, because they can neither avoid misapplication of the proposed criteria, nor clarify the unity in the concept of art.
