Robert A. Heinlein on Human Nature

"There is solemn satisfaction in doing the best you can for eight billion people. Perhaps their lives have no cosmic significance, but they have feelings. They can hurt."

"The United States had become a place where entertainers and professional athletes were mistaken for people of importance."

"As for population, every major shortcoming of our native planet could be traced to one cause: too many people, not enough planet."

"To be sure, some humans were always doing silly things—but at what point had prime damfoolishness become commonplace? When for example, had the zombie-like professional models become accepted ideals of American womanhood?"

"At least once every human should have to run for his life, to teach him that milk does not come from supermarkets, that safety does not come from policemen, that “news” is not something that happens to other people. He might learn how his ancestors lived and that he himself is no different—in the crunch his life depends on his agility, alertness, and personal resourcefulness."

"Must be a yearning deep in human heart to stop other people from doing as they please. Rules, laws — always for other fellow. A murky part of us, something we had before we came down out of trees, and failed to shuck when we stood up. Because not one of those people said: Please pass this so that I won't be able to do something I know I should stop. Nyet, tovarishchee, was always something they hated to see neighbors doing. Stop them for their own good."
