  As to the over-inclusiveness of aesthetic definitions, a distinction might be drawn between primary and secondary functions. Or it may be maintained that some cars, lawns, and products of industrial design are on the art/non-art borderline, and so don’t constitute clear and decisive counter-examples. Or, if the claim that aesthetic theories fail to account for bad art depends on holding that some works have absolutely no aesthetic value whatsoever, as opposed to some non-zero amount, however infinitesimal, it may be wondered what justifies that assumption.
