“The verdict to be passed on the third planet around Sol was never in doubt.”

“There is a misconception, geocentric and anthropomorphic, common to the large majority the the earthbound, which causes them to visualize a planetary system stereoscopically. The mind's eye sees a sun, remote from a backdrop of stars, and surrounded by spinning apples -- the planets. Step out on your balcony and look. Can you tell the planets from the stars? Venus you may pick out with ease, but could you tell it from Canopus, if you had not previously been introduced? That little red speck -- is it Mars, or is it Antares? Blast for Antares, believing it to be a planet, and you will never live to have grandchildren.”

“Nor would anybody suspect. If was one thing all people took for granted, was conviction that if you feed honest figures into a computer, honest figures come out. Never doubted it myself till I met a computer with a sense of humor.”

“I believe that this hairless embryo with the aching, oversize brain case and the opposable thumb, this animal barely up from the apes, will endure --will endure longer than his home planet, will spread out to the other planets, to the stars, and beyond, carrying with him his honesty, his insatiable curiosity, his unlimited courage --and his noble essential decency.This I believe with all my heart.”

“I want to spit back at a camel and ask him what he's so sour about. Maybe camels are the real 'Old Ones' on this planet ... and that what is wrong with the place.”

“Jill... had explained homosexuality, after Mike had read about it and failed to grok--and had given him rules for avoiding passes; she knew that Mike, pretty as he was, would attract such. He had followed her advice and had made his face more masculine, instead of the androgynous beauty he had had. But Jill was not sure that Mike would refuse a pass, say, from Duke--fortunately Mike's male water brothers were decidedly masculine, just as his others were very female women. Jill suspected that Mike would grok a 'wrongness' in the poor in-betweeners anyhow--they would never be offered water.”

“There are a dozen different ways of delivering destruction in impersonal wholesale, via ships and missiles of one sort or another, catastrophes so widespread, so unselective, that the war is over because that nation or planet has ceased to exist. What we do is entirely different. We make war as personal as a punch in the nose. We can be selective, applying precisely the required amount of pressure at the specified point at a designated time - we've never been told to go down and kill or capture all left-handed redheads in a particular area, but if they tell us to, we can. We will.”
