DY – Based on what I wrote earlier, I’m not sure I agree. Depends what you mean by “believe”. I think RSG’s right, therefore my understanding tells me it doesn’t exist, fine. I don’t believe, i.e. I reject the possibility, not fine.
Same as in Halachah. I have twenty proofs against a rishon, I pasken against him – but do I say “its wrong” ? We even say a pshat in a Rambam, despite knowing that it was not even his intent!
Its just more difficult to deal with the idea when it comes to things we consider “fact” – true or false. I think that just means we approach halachic ideas as so abstract, so we’re ok with “anything goes”.
