“It’s a wonder to be alive. If you don’t understand that, how can you search for anything deeper?”
“First: Survival is the primary need of civilization. Second: Civilization continuously grows and expands, but the total matter in the universe remains constant.”
We were afraid of you. “Is it because our thoughts aren’t transparent? That doesn’t matter, you know. All of the skills that you lack—deceit, trickery, disguise, and misdirection—we use in your service.” We don’t know if that’s true. Even supposing it is true, the fear remains. Your Bible mentions an animal called the snake. If a snake crawled up to you and said it would serve you, would your fear and disgust cease?
They imagined the shape and size of space battleships, debated the weaponry of space warfare, and even whether Mahan’s theory of sea power applied to space battles.…
“In my experience, any thinking is liable to go off the rails. You should just go to sleep.”
What he wanted wasn’t a fireplace, but the glow of the fire, for it is in firelight that a woman is most beautiful. He recalled how she had looked just then against the glow of the fire.…
For the majority of people, what they love exists only in the imagination. The object of their love is not the man or woman of reality, but what he or she is like in their imagination. The person in reality is just a template used for the creation of this dream lover. Eventually, they find out the differences between their dream lover and the template. If they can get used to those differences, then they can be together. If not, they split up. It’s as simple as that. You differ from the majority in one respect: You didn’t need a template.”
“In the face of this crisis, we are all ordinary people. But we all have our own responsibilities.”
Yan Yan, do you know what the greatest expression of regard for a race or civilization is?” “No, what?” “Annihilation. That’s the highest respect a civilization can receive. They would only feel threatened by a civilization they truly respect.”
The only constant in a world of tremendous change is the swift passage of time. Five years passed like a blur.
Winter was a season for thinking.
Don’t dismiss simplicity. Simple means solid.
“As I remember it, the serial numbers are set like this: the prefix digits represent the order of discovery; the letters J, E, and X stand for Jupiter-type planets, Earth-type planets, and other planets, respectively; and the digits following the letter indicate the number of that type of planet in the system.” “That’s right. 244J2E1 is a star with three planets, two of them Jupiter-type and one Earth-type.”
The French representative left his seat in his excitement. “Which is more tragic for humanity: the loss of the ability and right to think freely, or defeat in this war?”
“Why is it that everyone gets so sensitive at the mention of thought control? From commercial advertising to Hollywood culture, thought control is everywhere in modern society. You are, to use a Chinese phrase, mocking people for retreating a hundred paces when you’ve retreated fifty yourselves.”
Make time for civilization, for civilization won’t make time,’”
‘Make time for life, or life won’t make time.’
Genghis Khan’s cavalry attacked with the speed of twentieth-century armored units. The mounted crossbow of the Song Dynasty had a range of up to fifteen hundred meters, comparable to twentieth-century assault rifles. But it’s impossible for ancient cavalry and crossbows to compete with modern forces. Fundamental theory determines everything. The Future Historians clearly saw this point. You, on the other hand, have been blinded by the dying radiance of low-level technology and are luxuriating in the nursery of modern civilization, without any mental preparation whatsoever for the coming

“There are no permanent enemies or comrades, only permanent duty.”
“I wouldn’t usually bother the girls I liked. I believed in what Goethe said: ‘If I love you, what business is it of yours?’”
Dark. It’s so fucking dark.
‘If I don’t go to hell, who will?’
The universe had once been bright, too. For a short time after the big bang, all matter existed in the form of light, and only after the universe turned to burnt ash did heavier elements precipitate out of the darkness and form planets and life. Darkness was the mother of life and of civilization.
The past was like a handful of sand you thought you were squeezing tightly, but which had already run out through the cracks between your fingers. Memory was a river that had run dry long ago, leaving only scattered gravel in a lifeless riverbed. He had lived life always looking out for the next thing, and whenever he had gained, he had also lost, leaving him with little in the end.
In this forest, hell is other people. An eternal threat that any life that exposes its own existence will be swiftly wiped out. This is the picture of cosmic civilization. It’s the explanation for the Fermi Paradox.”
“Hiding the self through a faithful mapping of the universe is the only path into eternity.”
“I have a dream that one day brilliant sunlight will illuminate the dark forest.”
