Gilbert Keith Chesterton,
The New Jerusalem — Chapter XII: The Fall of Chivalry
(1920)
“ It was perhaps the one real age of progress in all history. Men have seldom moved with such rapidity and such unity from barbarism to civilisation as they did from the end of the Dark Ages to the times of the universities and the parliaments, the cathedrals and the guilds. Up to a certain point we may say that everything, at whatever stage of improvement, was full of the promise of improvement. Then something began to go wrong, almost equally rapidly, and the glory of this great culture is not so much in what it did as in what it might have done. ”
