Sestina of the Space Rocket (1953) 
Context: The way is open, comrades, free as Space
Alone is free. The only gold is love,
A coin that we have minted from the light
Of others who have cared for us on Earth
And who have deposited in us the power
That nerves our nerves to seize the burning stars.

Context: The truth is that you can be immortal, relatively so, anyway. You won't last beyond the death of the universe and probably not nearly as long as the universe does. But you have the potentiality for living a million years, two, perhaps three or more. As long as you can find a Terrestrial-type planet with a hot core and have resurrection machinery available.
Unfortunately, not all can be permitted to possess immortality. Too many would make immortality miserable or hellish for the rest, and they would try to control others through their control of the resurrection machinery. Even so, everybody, without exception, is given a hundred years after his Earthly death to prove that he or she can live peacefully and in harmony with himself and the others, within the tolerable limits of human imperfections. Those who can do this will be immortal after the two projects are completed.

Context: Burton, though an infidel, made it his business to investigate thoroughly every religion. Know a man’s faith, and you knew at least half the man. Know his wife, and you knew the other half.

Context: How strange and unforeseeable! The world had been saved, not by great rulers and statesmen, not by mystics and saints and prophets and messiahs, not by any of the holy scriptures, but by an introverted eccentric writer of mathematical texts and children's books and by the child who'd inspired him.
The little girl become a woman, dream-ridden Alice, had inspired the nonsense not really nonsense, and this in circuitous and spiralling fashion had inspired her to do what all others had failed to do, to save eighteen billion souls and the world.

Context: The visitor said that his kind called themselves the Ethicals, though they had other names for themselves. They were on a higher plane of ethical development than most Earthlings. Notice that he said most. This indicates that there have been some of us who have achieved the same level as the Ethicals.
