Linguist: One group of art critics claims that postimpressionist paintings are not really art and so should be neither studied nor displayed  Another group of critics disagrees, insisting that these paintings are works of art
But since the second group grants that there are paintings that are not works of art and should ttherefore be ignored in the manner suggested by the first group, their disagreement is not over the meaning of the word art
It is a claim whose acceptance by critics who differ on other issues is cited by the argument as evidence of its truth.
