Stephen Sears and this blogger agree that "today's dominant consensus about the war" is "exemplified" by James McPherson. Sears said so himself.
McPherson, exemplifying the ACW history consensus, believes that there is no new talent in Civil War publishing under the age of 40. He said so himself. Since he cannot see non-conforming history, or if he sees it he discounts it, the statement means that he cannot see any historians under 40 of his own ilk.
Perhaps the two statements (Sears' + McPherson's) together point to the end of consensus ACW history.
