In 1748, Scottish philosopher wrote an essay called Of 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.”
And:
”When anyone tells me, that he saw a dead man restored to life, I immediately consider with myself, whether it be more probable, that this person should either deceive or be deceived, or that the fact, which he relates, should really have happened.... If the falsehood of his testimony would be more miraculous, than the event which he relates; then, and not till then, can he pretend to command my belief or opinion.”
Hume hoped that this argument ”will, with the wise and learned, be an everlasting check to all kinds of superstitious delusion”.
In that, he was unfortunately incorrect, as we can tell almost 300 years later.
Now, we know a lot more about the universe, about history (especially the history of how religious texts were produced), about psychology, and so many other things, than we knew in the 18th century. But the beauty of Hume’s argument is that it doesn’t require any deep knowledge about science and history to understand it, or at least not deeper knowledge than humanity had in Hume’s days.
It is a simple, beautiful, and sound argument, and it is very easy to grasp. Certainly noteworthy in the history of skepticism.
