Hume on miracles

“no testimony is sufficient to establish a miracle, unless the testimony be of such a kind, that its falsehood would be more miraculous than the fact which it endeavors to establish.” This should make it clear that Hume is not saying that testimony could never establish the truth of a miracle, only that the standard of acceptance should be exceedingly high; as Sagan put it, given that we are trying to establish the truth of a very extraordinary claim, it stands to reason that we need an extraordinary degree of evidence to back up such a claim.
