William Olaf Stapledon

IS IT credible that our world should have two futures? I have seen them. Two entirely distinct futures lie before mankind, one dark, one bright; one the defeat of all man's hopes, the betrayal of all his ideals, the other their hard-won triumph.At some date within the age that we call modern, some date not precisely known to me, for I looked back towards it from the distant futures as though searching in my remote past, the single torrent of terrestrial events is split, as though by a projecting promontory, so that it becomes thenceforth two wholly distinct and mutually exclusive surging floods of intricate existence, each one a coherent and actual history, in which the lives of countless generations succeed one another along separate ravines of time.
