Human vs bug
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.
This is apparently said by Robert Heinlein’s character Lazarus Long in Time Enough for Love. The book focuses on the adventures and musings of Lazarus Long, the oldest living human, who has grown weary and has decided that life is no longer worth living. It takes the form of several novellas tied together in the form of Lazarus’s retrospective narrative. There is a reverse Arabian Nights theme to the novel, in that Lazarus will consent not to end his life as long as his companions will listen to his stories.
