" The much lauded objective evidence is never triumphantly there; it is a mere aspiration or Grenzbegriff [limit or ideal notion] marking the infinitely remote ideal of our thinking life … [But] when as empiricists we give up the doctrine of objective certitude, we do not thereby give up the quest or hope of truth itself. We still pin our faith on its existence, and still believe that we gain an ever better position towards it by systematically continuing to roll up experiences and think. Our great difference from the scholastic lies in the way we face. The strength of his system lies in the principles, the origin, the terminus a quo of his thought; for us the strength is in the outcome, the upshot, the terminus ad quem. Not where it comes from but what it leads to is to decide. "
