I don't believe that you can possibly separate expression from thought in an imaginative work. The better a thing is expressed, the more completely it is thought.
Virginia WoolfFor some time she observed a great yellow butterfly, which was opening and closing its wings very slowly on a little flat stone. "What is it to be in love?" she demanded, after a long silence; each word as it came into being seemed to shove itself out into an unknown sea. Hypnotized by the wings of the butterfly, and awed by the discovery of a terrible possibility in life, she sat for some time longer. When the butterfly flew away, she rose, and within, her two books beneath her arm returned again, much as a soldier prepares for battle.
Virginia WoolfShe came into a room; she stood, as he had often seen her, in a doorway with lots of people round her. But it was Clarissa one remembered. Not that she was striking; not beautiful at all; there was nothing picturesque about her; she never said anything specially clever; there she was however; there she was.
