“ The librarian was explaining the benefits of the Dewey decimal system to her junior—benefits that extended to every area of life. It was orderly, like the universe. It had logic. It was dependable. Using it allowed a kind of moral uplift, as one's own chaos was also brought under control.'Whenever I am troubled,' said the librarian, 'I think about the Dewey decimal system.''Then what happens?' asked the junior, rather overawed.'Then I understand that trouble is just something that has been filed in the wrong place. That is what Jung was explaining of course—as the chaos of our unconscious contents strive to find their rightful place in the index of consciousness. ”
