Take sex away from people. Make it forbidden, evil. Limit it to ritualistic breeding. Force it to back up into suppressed sadism. Then hand the people a scapegoat to hate. Let them kill a scapegoat occasionally for cathartic release. The mechanism is ages old. Tyrants used it centuries before the word "psychology" was ever invented. It works, too.
Robert A. HeinleinA human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects.
Robert A. HeinleinTo be matter-of-fact about the world is to blunder into fantasy - and dull fantasy at that, as the real world is strange and wonderful.
Robert A. HeinleinIn ascending order the qualities of Patriotism are: 1. To work, fight, or die for your own survival. 2. To work, fight, or die for your immediate family. 3. To work, fight, or die for a group, extended family, tribe, or clan. 4. To work, fight, or die for a group too large for all the individuals to know each other. 5. To work, fight, or die for a way of life.
