Now of course we must agree with Hume that, if there is absolutely "uniform experience" against miracles, if, in other words, they have never happened, why then they never have. Unfortunately, we know the experience against them to be uniform only if we know that all the reports of them are false. And we can know all the reports of them to be false only if we know already that miracles have never occurred. In fact, we are arguing in a circle.
