From the final scene of 'Things to Come', 1936, based a story by H. G. Wells
Passworthy: "I feel what we've done is monstrous!"
Cabal: "What we've done is magnificent."
Passworthy: "If they don't come back--my son and your daughter--what of that, Cabal?"
Cabal: "Then, presently, others will go."
Passworthy: "Oh, god, is there ever to be any age of happiness? Is there never to be any rest?"
Cabal: "Rest enough for the individual man--too much, and too soon--and we call it death. But for Man, no rest and no ending. He must go on, conquest beyond conquest. First this little planet with its winds and ways, and then all the laws of mind and matter that restrain him. Then the planets about him and at last out across immensity to the stars. And when he has conquered all the deeps of space and all the mysteries of time, still he will be beginning."
Passworthy: "But...we're such little creatures. Poor humanity's so fragile, so weak. Little...little animals."
Cabal: "Little animals. If we're no more than animals, we must snatch each little scrap of happiness and live and suffer and pass, mattering no more than all the other animals do or have done. Is it this--or that: all the universe or nothingness. Which shall it be, Passworthy? Which shall it be?"
