Randall Garrett, The price of eggs (1959)
“ Any civilization which appeared to be capable of lifting itself by its own bootstraps should do so; at this stage of the game, Man should not interfere. Of course, their very presence on the planet had already changed, somewhat, the course of Oassi's history, but that couldn't be helped; nothing can be observed without affecting it.The Shanni of Oassi appeared to be pleasantly impressed with Captain Smith, just as Newhouse had figured. She had certainly not been impressed by human males, which was perfectly understandable. ”
