"There is, it seems to us, At best, only a limited value In the knowledge derived from experience. The knowledge imposes a pattern, and falsifies, For the pattern is new in every moment And every moment is a new and shocking Valuation of all we have been. We are only undeceived Of that which, deceiving, could no longer harm."
