One of the foremost constitutional theorists of the founding generation, John Adams, observed, “Our Constitution was made only for a moral and religious People. It is wholly inadequate to the government of any other.”1
He wasn’t the only Founding Father to hold this view. Indeed, James Madison wrote that our Constitution requires “sufficient virtue among men for self-government,” otherwise, “nothing less than the chains of despotism can restrain them from destroying and devouring one another.”2
