There’s a volubility about Rauschenberg’s visual imagination that is irreconcilable with the discipline art demands. However monumental or panoramic a work of art may be, there must always be some acknowledgment of the limits of the artist’s vision. Rauschenberg didn’t know the meaning of the word “limits.” There was something of the outrageousness of a Ponzi scheme in the way he took this or that avant-garde idea and inflated it—over and over again.
