against these plain facts is always argument in a circle. If I say, "Mediaeval documents attest certain miracles as much as they attest certain battles," they answer, "But mediaevals were superstitious"; if I want to know in what they were superstitious, the only ultimate answer is that they believed in the miracles. If I say "a peasant saw a ghost," I am told, "But peasants are so credulous." If I ask, "Why credulous?" the only answer is--that they see ghosts. Iceland is impossible because only stupid sailors have seen it; and the sailors are only stupid because they say they have seen Iceland. It is only fair to add that there is another argument that the unbeliever may rationally use against miracles, though he himself generally forgets to use it. He may say that there has been in many miraculous stories a notion of spiritual preparation and acceptance: in short, that the miracle could only come to him who believed in it. It may be so, and if it is so how are we to test it? If we are inquiring whether certain results follow faith, it is useless to repeat wearily that (if they happen) they do follow faith. If faith is one of the conditions, those without faith have a most healthy right to laugh. But they have no right to judge. Being a believer may be, if you like, as bad as being drunk; still if we were extracting psychological facts from drunkards, it would be absurd to be always taunting them with having been drunk. Suppose we were investigating whether angry men really saw a red mist before their eyes. Suppose sixty excellent householders swore that when angry they had seen this crimson cloud: surely it would be absurd to answer "Oh, but you admit you were angry at the time." They might reasonably rejoin (in a stentorian chorus), "How the blazes could we discover, without being angry, whether angry people see red?" So the saints and ascetics might rationally reply, "Suppose that the question is whether believers can see visions--even then, if you are interested in visions it is no point to object to believers." You are still arguing in a circle--in that old mad circle with which this book began.
