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, Science Fiction author, in “Time Enough for Love”
If Heinlein is right, then the modern world is largely maintained by “insects”. While religious institutions and scientific researches were all things to all people, answering the overarching questions about the meaning of life and how everything fit and work together, the proliferation of specialties is a characteristic of a world with complex operational requirements. Though the priest may understand how something will affect your eternal life, and scientists may speculate on the origins of the universe, it is unlikely that they can advise you on your tax payments as well as a university degree.
