Gilbert Keith Chesterton,
The Barbarism of Berlin
(1914)
“ The promise, like the wheel, is unknown in Nature: and is the first mark of man. Referring only to human civilisation, it may be said with seriousness that in the beginning was the Word. The vow is to the man what the song is to the bird, or the bark to the dog; his voice, whereby he is known. Just as a man who cannot keep an appointment is not fit even to fight a duel, so the man who cannot keep an appointment with himself is not sane enough even for suicide. It is not easy to mention anything on which the enormous apparatus of human life can be said to depend. ”
