A miracle is a violation of the laws of nature; and because firm and unalterable experience has established these laws, the case against a miracle is—just because it is a miracle—as complete as any argument from experience can possibly be imagined to be. Why is it more than merely probable that all men must die, that lead cannot when not supported remain suspended in the air, that fire consumes wood and is extinguished by water, unless it is that these events are found agreeable to the laws of nature, and for things to go differently there would have to be a violation of those laws, or in other words a miracle? Nothing is counted as amiracle if it ever happens in the common course of nature. When a man who seems to be in good health suddenly dies, this isn't a miracle; because such a kind of death, though more unusual than any other, has yet often been observedto happen. But a dead man’s coming to life would be a miracle, because that has never been observed in any age or country. So there must be a uniform experience against every miraculous event, because otherwise the event wouldn't count as a ‘miracle’. And as a uniform experience amounts to a proof, we have here a direct and full proof against the existence of any miracle, just because it’s a miracle; andsuch a proof can’t be destroyed or the miracle made credible except by an opposite proof that is even stronger.This clearly leads us to a general maxim that deserves ofour attention:No testimony is sufficient to establish a miracle unless it is of such a kind that its falsehood would be more miraculous than the fact that it tries to establish. And even in that case there is a mutual destruction ofarguments, and the stronger one only gives us an assurance suitable to the force that remains to it after the force needed to cancel the other has beensubtracted.
