All the livid steeds of the Apocalypse have stormed through my life — revolution and famine, inflation and terror, epidemics and emigration. I have seen the great mass ideologies grow and spread before my eyes — Fascism in Italy, National Socialism in Germany, Bolshevism in Russia, and above all else that arch-plague nationalism which has poisoned the flower of our European culture.

Stefan Zweig (1881-1942) Austrian novelist, playwright, journalist, biographer

Alternate translation [Sonnenfeld]:

All the pale horses of the apocalypse have stormed through my life, revolution, starvation, devaluation of currency and terror, epidemics, emigration; I have seen the great ideologies of the masses grow and spread out before my eyes. Fascism in Italy, National Socialism in Germany, Bolshevism in Russia, and, above all, that arch-pestilence, nationalism, which poisoned our flourishing European culture.
