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 and die gallently.
Specialization is for insects.
-- Robert Heinlein
