 From this it follows that if the future holds any new discoveries or any new developments in the growth of our knowledge, then it is impossible for us to predict them now, and it is therefore impossible for us to predict the future development of human history now, given that the latter will, at least in part, be determined by the future growth of our knowledge. Thus, once again historicism collapses—the dream of a theoretical, predictive science of history is unrealisable, because it is an impossible dream.
