My problem with classifications is, that they don't last; as soon as I have finished a certain order, it is already lapsed. Like everyone else I sometimes have a mania of ordering things. But because of the abundance of things to be ordered and the near impossibility of ordering them into a satisfying classification, I never come to an end. I have to stop with provisory and vague order, which seldom is more effective than the previous disorder.
