"There was a time... when no political idea of the 20th century was comparable to communism (or the October Revolution as its symbol), a time when nothing attracted Western intellectuals and people all around the world more powerfully or emotionally. Raymond Aron called the Russian Revolution the “opium of intellectuals.” But the idea of communism is at least two thousand years old. We can find it in Plato’s teachings about an ideal, correct state; in Aristophanes’ dreams about a time when “everything will belong to everyone.” … In Thomas More and Tommaso Campanella … Later in Saint-Simon, Fourier and Robert Owen. There is something in the Russian spirit that compels it to try to turn these dreams into reality."
