The slogan “The Five Year Plan in Four Years” was advanced, and the magic symbols “5-in-4” and “2 + 2 = 5” were posted and shouted throughout the land. The formula 2 + 2 = 5 instantly riveted my attention. It seemed to me at once bold and preposterous—the daring and the paradox and the tragic absurdity of the Soviet scene . . . 2 + 2 = 5: in electric lights on Moscow housefronts, in foot-high letters on billboards, spelled planned error, hyperbole, perverse optimism . . . a slogan born in premature success tobogganing toward horror.
