The thing about historians is that you don't have to turn over many rocks to discover one, and they all have opinions on any and every side. The trick is not to believe any one of them, but to take their opinions, look at the evidence, and come to your own conclusions, because you have as much right to yours as they have to theirs. It's a peculiarly French trick to dissuade you from looking at the original data and have to rely on the experts, forgetting the definition of an expert. This is particularly important in History at the moment, given that the discrepancies which riddle the different National versions would amount in a scientific subject to a summary dismissal of the entire thing as a fabulation.
And if you can't manage that, then the stopping point is at the end of the last paragraph.
