human-capabilities

"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."
