Sandefur: "John Adams insists the American constitutions were not divinely inspired"

We've seen this quotation before; but it's always worth a revisit. A taste:

It will never be pretended that any persons employed in that service had interviews with the gods, or were in any degree under the inspiration of Heaven, more than those at work upon ships or houses, or laboring in merchandise or agriculture; it will forever be acknowledged that these governments were contrived merely by the use of reason and the senses.... Neither the people, nor their conventions, committees, or sub-committees, considered legislation in any other light than as ordinary arts and sciences, only more important.
