It’s not referring to a book title. The original Constitution as written capitalizes various nouns because that was the style then. You are sadly mistaken if you think it is referring to a specific book title. Find one single reputable source that believes that. You cannot. Do your own research. Stop believing things you hear and verify what you read. Verify what *I* say.
I have read about Laws On Nation in multiple places over the last few days. All the Supreme Court decisions referred to this specific text.
You’re way in over your head, buddy!
