Alan Jacobs quoting Stella (Thelma Ritter) in Hitchcock’s Rear Window (1954):
Nothing has caused the human race so much trouble as intelligence.
its preservation was owing merely to the fact that their gardener was blessed with a wholesome stupidity rendering him incapable of unlearning what his father, who had been gardener there before him, had had marvellous difficulty in teaching him. We do not half appreciate the benefits to the race that spring from honest dullness. The clever people are the ruin of everything.
The more cleverness, the more strange events
Simpletons! Yes, yes! I’m a simpleton! Are you a simpleton? We’ll build a town and we’ll name it Simple Town, because by then all the smart bastards that caused all this, they’ll be dead! Simpletons! Let’s go! This ought to show ‘em! Anybody here not a simpleton? Get the bastard, if there is!
