Hamann agreed with Mendelssohn that there are “no eternal truths save as incessant temporality,” and in this he locates the difference between Judaism and Christianity: “it is solely a matter of temporal truths of history, which occurred once and never come again – of facts which have become true at one point in time and place through a coherence of causes and effects, and which, therefore, can only be conceived as true in respect to that point in time and space, and must be confirmed by authority.” Authority, he recognizes, can suppress reason, but he adds, again following Mendelssohn, that “without authority the truth of history vanishes along with the event itself.”
