  Aesthetic definitions have been criticized for being both too narrow and too broad. They are held to be too narrow because they are unable to cover influential modern works like Duchamp’s ready-mades and conceptual works like Robert Barry’s All the things I know but of which I am not at the moment thinking – 1:36 PM; June 15, 1969, which appear to lack aesthetic properties. (Duchamp famously asserted that his urinal, Fountain, was selected for its lack of aesthetic features.) Aesthetic definitions are held to be too broad because beautifully designed automobiles, neatly manicured lawns, and products of commercial design are often created with the intention of being objects of aesthetic appreciation, but are not artworks. Moreover, aesthetic views have been held to have trouble making sense of bad art (see Dickie 2001; Davies 2006, p. 37). Finally, more radical doubts about aesthetic definitions center on the intelligibility and usefulness of the aesthetic. Beardsley’s view, for example, has been criticized by Dickie, who has also offered influential criticisms of the idea of an aesthetic attitude (Dickie 1965, Cohen 1973, Kivy 1975).
