> eighteenth-century guys couldnt have possibly foreseen the culture and technology of today <
Judge Posner is right about that! The Founding Fathers stupidly did not include an amendment process in the Constitution. So there is no way to update it. Oh, wait...there is an amendment process in the Constitution.
Maybe Posner was absent the day they covered that in law school.
If the Founders couldn’t have foreseen today’s culture, its because they were sane men.
