In fact, we are arguing in a circle. So Hume s argument has some serious problems. But let s cut him a little slack. Theologian Norman Geisler has noted that Hume s arguments can be given a softer interpretation than the one above. A miracle is by definition a rare occurrence.
Natural law is by definition a description of regular occurrence.
The evidence for the regular is always greater than the evidence for the rare. A wise man always bases his beliefs on the greater evidence. Therefore, a wise man should never believe in miracles. At first glance, this appears a bit more reasonable. Hume is not saying that miracles can t occur, only that they re rare.
