A couple of quotes I liked - cited in a book I'm reading about the Quay Brothers' films. The book is a little too theoretical for my liking, but the sources are interesting.
"...theorizing is what one does in the barren intervals between good films: once one's enthusiasm for the last work has died down, one finds oneself stranded in an imageless wilderness, and, left with nothing to think about, one begins to think abstractly."
- Paul Coates
"The writer is not tied to the physical concreteness of a given setting; therefore, he is free to connect one object with another even though in actuality the two may not be neighbours either in time or in space. And since he uses as his material not the actual percept but its conceptual name, he can compose his images of elements that are taken from disparate sensory sources. He does not have to worry whether the combinations he creates are possible or even imaginable in the physical world. . . . The writer operates on what I called the second or higher level, at which the visual and auditory arts also discover their kinship. We understand now why the writer can fuse the rustling of the wind, the sailing of the clouds, the odour of rotting leaves, and the touch of raindrops on the skin into one genuine unity."
