Never true,' Old Ben would say. 'Useful- now, there's something. Your mind might make a connection that is useful. But true is another matter. True implies that you have found a connection that exists independent of your apprehension of it, that would exist whether you noticed it or not. And I must say that I have never seen such a connection in my life. There are times when I suspect there are no such connections, that all links, bonds, ties, and similarities are creations of thought and have no substance.
