"The notion of invasions by aliens was a projection of the aggressive traits of the predatory, barely civilized ape-man. If he himself willingly did unto others as he would rather not be done by, then he pictured the Advanced Civilization on much the same principle. Flotillas of galactic battleships were supposed to fall upon unsuspecting little planets, to lay hands on the local dollars, diamonds, chocolates, and, of course, beautiful women — for whom aliens had about as
much use as we did for female crocodiles."
