Ray Bradbury

“ Man against man, ship against ship—a ceaseless and useless orgy of slaughter. Men, at their battle stations in the ships, pressed buttons, releasing radio bombs that blistered space and lifted whole cities up in shattered pieces and flung them down, grim ruins, reminders of man's ignorant hatreds and suspicions.
And gas—thick black clouds of it—billowing over the cities, seeking every possible egress, pushed forward by colossal Wind machines. ”

“ It is doubtless but what the entire human race would have vanished, leaving the world to the more competent, though half-ignorant, hands of the beasts, who fought and killed one another for self-preservation and for food—not because of madness... ”

“ Through the ages people have hungered after luxury and leisure—but when he finds his food, a lot of it, MAN finds suddenly that it no longer appeals to him. In fact, too much is bound to make him sick and often disagreeable. ”

“ There was physics, biology, anthropology, zoology, geology, bacteriology, botany—and 'ologies' and 'otonies' and 'onomies' such as ran into figures which only machines could calculate.
A book could indeed have been written of the accomplishments of super race. But this is of the WAR itself, and how it came about, and how it all ended.
Stated simply, in 2150 the point of DIMINISHING UTILITY had been reached. To the hungry man, the first course of dinner is wonderfully delicious, the second good, the third satisfying. ”

“ The ancestor of the Eohippus, the little four-toed Dawn Horse, was discovered; the direct line between man and ape established in skeletal remains; the seat of life itself definitely proved Holarctica. ”

“ In the regulated climates of long dead ages, fish, amphibians, reptiles, birds and mammals lived again for the edification of those interested in the very ancient—or who were amused with queer animals. ”
