Burke cited great its economic progress and more. At that time, of course, there had been no Declaration of Independence, with its "encapsulation" Lincoln of abstract principles, etc. There were just the astounding numbers he could document in order to show his admiration and awe at what was happening in America.
On the other hand Frothingham's 1886 "Rise of the Republic..." was a backward look across the two centuries since the settlers had come to America, and he, too, with the advantage of having read other historians, could view the consequences of the ideas which had motivated those who had come here and accomplished such great things on behalf of individuals all over the globe.
Sadly, we have neglected such histories in favor of rewritten versions of our history, written by persons whose agenda controlled their writings, and we are, today, reaping the consequences of our neglect of the heritage of liberty left to us by those generations.
