'Through a suddenly lit arch in the cave of the mind, images of salt-dusted plains open up; winding paths along cliffs torn high above acidic tides; desire-lines scrawling away through serrated uplands and beyond to a tar horizon. The cave of the mind we leave, so dense with bats and thoughts, a subterrain of the senses, has offered us this: our two legs, scissors cutting away the dross; our feet, padded sensors returned tot he earth's slow philology; our heart, cradled in its basketry of ribs, sending a receiving prey and game from the brain.'
