All art is infested by other art.
...it is in the nature of original contemporary art to present itself as a bad risk. And we the public...should be proud of being in this predicament, because nothing else would seem to us quite true to life; and art, after all, is supposed to be a mirror of life.
Whatever else art is good for, its chief effectiveness lies in propagating more art.
If a work of art or a new style disturbs you, then it is probably good work. If you hate it, it is probably great.
