I agree Penny. One can take a fact and see it more than one way. 1 + 1 = 2. If I'm selling candy at the price of 2 cents a piece, it's right. If I'm a buyer, I may want to check out the stores in the area to see if they are selling at the same price. One textbook does not mean the true story is being told.
'Trained Historian', no disrespect meant to anyone but that sounds like a trained seal, or dog. Trained, as in learn by rote.
'Learned Historian', that is one who can read facts and place them into the larger scope of the era, subject, whatever. One who thinks, not repeats.
