“Art is anything you can get away with” …. for Canadian philosopher Marshall McLuhan During the peak of contemporary art, art became something to go “against art” or “show society”. It was probably sparked by cubism beforehand. Look up Dada art or performance art, probably the most prominent in that period which was basically a school of artists who decided that they’d take ordinary objects and put it in a gallery to make it art purposely to show that it was art.
Though the statement might’ve been somewhat of a mock on art, but it was true and Warhol definitely embraced it.
