" Since , hoever, most words are no more than increasigly abstract generalizations, they can never convey the full singular essence of any particular object, feeling or happening - logic is to real thought as corned beef and canned beef are to natural products. Geniuses when at work think largely in pictorial images, and the consequent exactness of their thought tempts logicians to dismiss them as liars, guessers or madmen. " Robert Graves ( Lectures )
