From In the Shadow of Tomorrow (1935) by Johan Huizinga:

We are living in a demented world. And we know it. It would not come as a surprise to anyone if tomorrow the madness gave way to a frenzy which would leave our poor Europe in a state of distracted stupor, with engines still turning and flags streaming in the breeze, but with the spirit gone. Everywhere there are doubts as to the solidity of our social structure, vague fears of the imminent future, a feeling that our civilization is on the way to ruin. They are not merely the shapeless anxieties which beset us in the small hours of the night when the flame of life burns low. They are considered expectations founded on observation and judgment of an overwhelming multitude of facts. How to avoid the recognition that almost all things which once seemed sacred and immutable have now become unsettled, truth and humanity, justice and reason? We see forms of government no longer capable of functioning, production systems on the verge of collapse, social forces gone wild with power. The roaring engine of this tremendous time seems to be heading for a breakdown.
