What is also interesting is the silence--it means that the established panjandrums can't articulate an objection. I'm sure you've heard of Simon Schama from his fine arts work, and he is also an historian of high repute in areas other than art. He wrote a small book several years ago in which he advanced the hypothesis that James Wolfe committed suicide by combat before Québec in 1759. His reputation is too well established to be challenged, and the only challenge which could have been offered would have been "no he didn't." He makes his case quite well, and it is interesting that among Canadian historians, not only is that not challenged, it was articulated in Canadian historical circles before Schama's book. Wolfe's personal papers and effects are in Canada.
People of lesser reputation can be ruined. In 1968, the mummy of Ramses II arrived in Paris where the body and the cerements were to be studied by French scientists using what was then the leading techniques for such research. One young woman, a recently passed doctoral candidate, found vegetable matter in the cerements which she identified as tobacco. Egyptologists are some of the worst of the lot when it comes to defending established positions, and she wasn't met by silence, but by derision. Her career was ruined, she couldn't find a place in the academic world. Nobody challenged her assertion, and it was impossible for them to allege contamination without queering their own pitch--so she was attacked on the "everybody knows" basis--in that case, that everybody knows that there was no commerce between the new world and the old that long ago. Poor woman.
