I read this as a comment using "enlightenment" in a way we sometimes hear from preachers where the word is defined as "the state of being enlightened: to live in spiritual enlightenment."Where do you suppose that enlightenment came from?
This is the sort of thing that happens when children are not taught their heritage in schools.
The Enlightenment was a philosophical school of thought which for the most part rejected theological thinking as too restrictive. It combined the new knowledge that was being gained thru scientific experimentation with different ways of looking at human governance, ways other than the divine right of monarchs to rule over their subjects. Philosophy in the 18th C had a very different meaning than it does at this time.
"How did those values differ from the founders of the United States?" They didn't and that is the point, Enlightenment thinking provided an alternative to the traditional Judeo-Christian pattern of the years since the Roman Empire.
