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, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects.

一个人应该能够更换尿布,策划战争,杀一头猪,开船掌舵,设计建筑,写十四行诗,会计结算,粉刷砌墙,治疗脱臼,安慰临终的人,执行命令,发布命令,携手合作,独立行动,解数学方程,分析问题,施肥铲粪,电脑编程,做可口的饭菜,高效地战斗,勇敢地死去。只有昆虫才专业化。
