Author Maurice Genevoix, who was a military officer during that war, said of it: “Everyone agrees in recognizing that in the whole history of mankind, few dates have had the importance of August 2, 1914. First Europe and soon after almost all humanity found themselves plunged into a dreadful event. Conventions, agreements, moral laws, all the foundations shook; from one day to the next, everything was called into question. The event was to exceed both instinctive forebodings and reasonable anticipations. Enormous, chaotic, monstrous, it still drags us in its wake.”​—Maurice Genevoix, member of the Académie Française, quoted in the book Promise of Greatness (1968).

On August 4, 1979, just 65 years after the outbreak of World War I, The Economist, of London, England, commented: “In 1914 the world lost a coherence which it has not managed to recapture since.”
