"Well, one of the problems about being psychoanalyzed is, as Nietzsche said, "Be careful lest in casting out your devils that you cast out the best thing that's in you." So many people who are really in deep analysis look as though and act as though they have been filleted. There's no bone there, there's no stuff! How to get rid of ego as dictator and turn it into messenger and servant and scout, to be in your service, is the trick."

In the final analysis the hierarchic pattern is nothing like the straightforward witness for organic evolution that is commonly assumed. There are facets of the hierarchy which do not flow naturally from any sort of random undirected evolutionary process. If the hierarchy suggests any model of nature it is typology and not evolution. How much easier it would be to argue the case for evolution if all nature's divisions were blurred and indistinct, if the systema naturalae was largely made up of overlapping classes indicative of sequence and continuity.
