It is for this reason that some Skeptics assert that revelation from God is necessary. Ordinary skeptics may be atheists and be completely unaware of the arguments of theological Skepticism. The ordinary skeptic may be an atheist simply because he or she perceives little, if any, evidence for the belief in God. In addition to providing philosophical doubts about metaphysics, some Skeptics aimed their arguments at specific types of claims. Basically, Hume argues that for the same reason it is reasonable to avoid the vicious dog trying to bite us, it is reasonable to reject miraculous claims.
Miraculous claims assert that a violation of the laws of nature has occurred.
Laws of nature are based on experience. Experience is our guide in avoiding the vicious dog and must be our guide in judging the miraculous event. To accept an event as miraculous is to accept that experience is not a reliable guide, but it is our only guide in such matters, unless we abandon reason and believe on pure faith. It seems that it would apply to things such as homeopathy , channeling , astral projection , levitation , past life regression , psychic surgery , map dowsing , and other things which require us to abandon experience as a guide. Claims about ESP , however, would not be covered by the argument, unless advocates maintain that ESP occurs outside the realm of the laws of nature.
