We do not take moonlight for granted. It is like snow, or like the dew on a July morning. It does not reveal but changes what it covers. And its low intensity—so much lower than that of daylight—makes us conscious that it is something added to the down, to give it, for only a little time, a singular and marvelous quality that we should admire while we can, for soon it will be gone again.
