what one calls an earlier time is the period of which one has oneself known only the end: things that we see on the horizon assume a mysterious grandeur and seem to us to be closing over a world which we shall not behold again; but meanwhile we are advancing, and very soon it is we ourselves who are on the horizon for the generations that come after us; all the while the horizon retreats into the distance, and the world, which seemed to be finished, begins again.
