One of the more interesting posts in recent months at Left2Right, courtesy of historian James Oakes.  His conclusion (for which his post provides the support):

The wave of evangelicalism that swept the United States beginning in the 1790s was not really a "second" Great Awaking at all.  It was not a continuation of the earlier failure.  It was something else.  What, precisely?  Well, nothing "precisely," but a lot of things.  And one of the things that evangelicalism was in the "New Nation," I suggest, was a reactionary assault on the secular humanism of the Revolution. 

It still is.
