 Second, conceptual art poses philosophical problems from a wider perspective, in so far as one might expect philosophy to provide us with unitary accounts of the nature of art, the role of the artist, and artistic experience. In many important respects, conceptual art sits very uncomfortably with other, often more traditional artforms and artworks, and this tension highlights a pressing issue for anyone interested in the possibility of a universal theory of art. For if there is to be one rule for conceptual art and another for all other kinds of art, are there still good grounds for thinking of conceptual art as a kind of art? Moreover, could not every particular kind of artform or artwork demand a separate theory of art, artist and artistic experience?
