Now something that you formerly loved as a truth or probability strikes you as an error; you shed it and fancy that this represents a victory for your reason. But perhaps this error was as necessary for you then, when you were still a different person —you are always a different person —as are all your present 'truths,' being a skin, as it were, that concealed and covered a great deal that you were not yet permitted to see. What killed that opinion for you was your new life and not your reason: you no longer need it, and now it collapses and unreason crawls out of it into the light like a worm. When we criticize something , this is no arbitrary and impersonal event; it is, at least very often, evidence of vital energies in us that are growing and shedding a skin. We negate and must negate because something in us wants to live and affirm— something that we perhaps do not know or see as yet.
