Here is one of Hume's stock objections to reported miracles:
[T]here is not to be found, in all history, any miracle attested by a sufficient number of men, of such unquestioned good sense, education, and learning, as to secure us against all delusion in themselves; of such undoubted integrity, as to place them beyond all suspicion of any design to deceive others; of such credit and reputation in the eyes of mankind, as to have a great deal to lose in case of their being detected in any falsehood; and at the same time attesting facts, performed in such a public manner, and in so celebrated a part of the world, as to render the detection unavoidable: All which circumstances are requisite to give us a full assurance in the testimony of men.
However, Hume's objection easily reversible. Suppose the "educated and learned" move in social circles where belief in miracles is disdained as backward superstition–or worse? If they value their reputation, they have a powerful incentive to remain mum about a miracle even if they were to witness a miracle, or hear a credible report of a miracle from someone they trusted.
Indeed, this is more than hypothetical. We live in a time and place where peer pressure among the "educated and learned" deters the elites from admitting to belief in miracles.
