"Class of 2015, you should not leave Stone Ridge High School thinking that you face challenges that are at all, in any important sense, unprecedented," he said. "Humanity has been around for at least some 5,000 years or so, and I doubt that the basic challenges as confronted are any worse now, or alas even much different, from what they ever were."
So why that specific number, 5,000? It just so happens to be right around what those who take a literal view of the creation story in Genesis believe the age of the earth to be. (Current year in the Hebrew calendar: a nicely palindromic 5775.) Surely a coincidence, yes? Well, Scalia's right: We're still facing the same old challenges as we always have—in this case, rank ignorance.
