Scott added he would say to historians questioning the accuracy of his storytelling:
“Were you there? Oh you weren’t there. Then how do you know?”
Because the people who were there wrote it down, and now we can read it. Scott's line of reasoning is inherently inconsistent because if followed it would mean we have to evidence of Napoleon Bonaparte existing in the first place. Boy is Ridley Scott going to feel dumb when he realizes he made a biopic of a mythical character combined from the real stories of several French generals after the revolution—if there even was a French Revolution, I mean, we weren't there.
Is there anything more embarrassing than people who think they know better than historians and reject the entire discipline of historiography? It's like being anti-vax but extended to everything you don't personally see.
