“The [years 1900-1910] were nothing if not dynamic. Everything appeared bigger today than it had yesterday: cities, industrial production, railway networks, streets with automobiles hurtling along, high-rise buildings with stern facades, populations, media and entertainment, mass culture, speed records. Gripped between the steely jaws of industry and the emerging global market, millions were uprooted and forced to invent new identities in an unfamiliar world.

Despite this dynamism, the spectre of degeneracy and decline was a haunting, constant presence in European minds. Eugenicists warned about the decline of the race; conservative publicists foretold the end of civilization; empires anxiously eyed one another’s military might. Never before had there been so much reason to be optimistic, and never before had people looked towards the future with stronger misgivings.”

Philipp Blom, historian, The Vertigo Years: Europe, 1900–1914, published in 2008
