For what is life but greed in action? - Fritz Leiber

“Life’s always been a business of working hard and fighting the cold,” Pa was saying. “The earth’s always been a lonely place, millions of miles from the next planet. And no matter how long the human race might have lived, the end would have come some night. Those things don’t matter. What matters is that life is good. It has a lovely texture, like some thick fur or the petals of flowers—you’ve never seen those, but you know our ice-flowers—or like the texture of flames, never twice the same. It makes everything else worth while. And that’s as true for the last man as for the first.”

“Conscience is only social pressure,” he told her, tense without quite knowing why, “the impulse to submerge your ego in that of the herd, and do what other people want you to because you’re afraid of their censure. Realistic self-interest frees a person from the childish restrictions of conscience.”
“Are you sure of that, Jarles? What about your dreams? Conscience may be partly what you say it is, but it’s more than that. It’s hearkening to the wisest thoughts that have occurred to the minds of the human race.”

Things are different from what I thought. They’re much worse.
