"Smith is not a man.  He is an intelligent creature with the genes and ancestry of a man, but he is not a man.  He's more a Martian than a man.  Until we came along he had never laid eyes on a human being.  He thinks like a Martian, he feels like a Martian.  He's been brought up by a race which has nothing in common with us.  Why, they don't even have sex.  Smith has never laid eyes on a woman - still hasn't if my orders have been carried out.  He's a man by ancestry, a Martian by environment.  Now, if you want to drive him crazy and waste that 'treasure trove of scientific information,' call in your fat-headed professors and let them badger him.  Don't give him a chance to get well and strong and used to this madhouse planet.  Just go ahead and squeeze him like an orange.  It's no skin off me; I've done my job!"
