You are falling victim to fallacious ad populum argumentation, GE. Because internet philoophers love to rail on about fallacies, you accept that near universal belief in some fact is "not evidence that it is true".
That is correct. It is not evidence. I suggested previously that you don't understand what constitutes evidence. I gave you a link discussing that subject. Apparently you've ignored or dismissed that explanation. I doubt that I can say anything more convincing than the example given concerning Mercury's orbit providing evidence for the theory of relativity. The evidence for that theory is not Einstein's beliefs, or the beliefs of the astronomers who computed Mercury's orbit, but the facts they reported.
Are you perhaps confusing a reported observation that
P with someone's belief that
P? Those are quite different things. We do, of course, routinely, even constantly, accept facts reported by others --- if my co-worker, looking out a window, says, "It's raining outside," I take his word for it. Exchanging information is, after all, the primary purpose of language. The evidence for his claim, however, is not his belief that it is raining, but the phenomenon he is reporting. I'll take his word for it until/unless I have some reason to doubt it (perhaps I'd looked out 5 minutes ago and it was not raining).
Nonetheless, neither you nor I know what "historical records support that claim (that Napoleon's troops fought the Battle of Borodino)." Instead, we accept the universal verdict of propfessional historians (possibly because we believe they have dilligently perused the historical records).
Well, there are very few "universal verdicts" among historians. But your paranthetical clause there answers the question. We accept what they say,
not because they say it or believe it, but because we assume they can produce some evidence for that claim. When that assumption is not warranted their beliefs count for nothing.
This discussion began, you may recall, with your denial of my claim that persons have no
a priori duties, such as a duty to meet others' needs. You claimed there is such a duty, deriving from the Golden Rule, which must be sound because "It's been the foundation of Western morality for 2000 years."
That is an
ad populum argument. It hasn't, but even if it had been, that fact supplies no evidence or argument for its soundness. Until its adherents can supply those, belief in neither the GR nor that duty is warranted. Nor does the Golden Rule entail that duty (many people would not force others to meet their medical needs, and hence, per the GR, have no duty to meet others' similar needs).
