Abstract
"Prophecy by magic is a myth. But prophecy by science is a fact." With these words, Lenin begins his article "Prophetic Words" [Prorocheskie slova], in Poln. sobr. soch. [Complete Works], Vol. 36, p. 472. Written in the middle of 1918, a very difficult time for the young Soviet republic, it is devoted entirely to Engels' forecast three decades earlier of the possible outcomes of a world war. With amazing forecasting ability, Engels described the destruction and upheavals that war would cause, the downfall of capitalist empires and the inevitable triumph of the proletariat. Engels warned the kings and statesmen of the capitalist class: "If you unleash forces with which you will not subsequently be able to contend, then, no matter how things develop, at the end of the tragedy you will be a ruin, and the triumph of the proletariat will either already have been won or in any case be inevitable."
