 Until now history has been contrary to reason. In Greece the two terms “reason” and “history” were opposed. And until now, in effect, hardly anyone has been concerned to search in history for its rational substance…. Hence the expression “historical reason” must be understood in all the rigor of the term. Not an extrahistorical reason which appears to fulfill itself in history but, literally, a substantive reason constituted by what has happened to man, the revelation of reality transcending man’s theories and which is himself, the self underlying his theories (Obras, VI: 49–50).
