"Yale was founded by finicky Protestants who worried that the Puritans at Harvard weren't puritanical enough. But the Revolutionary War brought the Age of Reason to New Haven, and (Timothy) Dwight (Jonathan Edwards' grandson) inherited a student body full of deist beatniks on the Enlightenment highway to hell, which is to say, France. This generation did not just read Voltaire - they literally addressed each other as 'Voltaire' the way kids today call one another dude. Like, 'Voltaire, I'm so high right now.'"
