The poet's discourse can be compared to the track of a charged particle through a cloud-chamber. An energised field of association and connotation, of overtones and undertones, of rebus and homophone, surround its motion, and break from it in the context of collision. . in Western poetry so much of the charged substance is previous poetry.
Painting is. . . a richer language than words. . . Painting operates through signs which are not abstract and incorporeal like words. The signs of painting are much closer to the objects themselves.
