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. –Robert A. Heinlein
Civilians are like beans;
you buy ’em as needed for any job which merely requires skill and savvy.
But you can’t buy fighting spirit.
–Robert A. Heinlein
