A 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, analyse a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects. - Robert Heinlein 一个人应该能够换尿布，策划战争，杀猪，开船，设计房子，写十四行诗，结算账户，砌墙，接脱臼的骨头，安慰濒死的人，服从命令，发布命令，携手合作，独立行动，解数学方程，分析新问题，铲粪，电脑编程，做出可口的饭，善打架，勇敢地死去。只有昆虫才专业化。 罗伯特·海因莱茵
