“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 – Time Enough for Love
What separates humans from the insects in a nutshell. Robert A. Heinlein is recognised as one of the leading lights of the Golden Age of science fiction along with Arthur C Clarke and Isaac Asimov. He is responsible for some of the seminal works of science fiction which have influenced popular culture and modern thought. He obviously didn’t think much of the man who couldn’t change a car tyre.
