I was trawling through some old notes looking for a specific quote and came across this one from Kurt Vonnegut’s Slaughterhouse 5. I’m yet to find what I was looking for, but this was pretty good.
Kilgore Trout became Billy’s favorite living author, and science fiction became the only sort of tales he could read.
Rosewater was twice as smart as Billy, but he and Billy were dealing with similar crisis in similar ways. They had both found life meaningless, partly because of what they had seen in war. Rosewater, for instance, had shot a fourteen-year-old fireman, mistaking him for a German soldier. So it goes. And Billy had seen the greatest massacre in European history, which was the fire -bombing at Dresden. So it goes.
So they were trying to re-invent themselves and their universe. Science fiction was a big help.
