I've been working on a paper about problems with believing the evidence for the miracles of Jesus. I have put a draft of the paper here and would gladly get input from interested parties.
Problems for the Miracles of Jesus
The central idea is that in order for a person to accept some conclusion p on the basis of evidence E, then he or she needs to be confident that if p wasn't true, some indications of that could show up in E. What that means is that I shouldn't believe sources that indicate p is true unless there's a reasonable expectation that they would have informed me that p was false if that had been the case. Here's the principle:
Counter Evidence Principle (CEP): S would be reasonable in concluding that p is true on the basis of the evidence E only if it is reasonable for S to believe that the evidence E would indicate ~ p if ~p had been the case.
On the basis of cognized situation s, human H is entitled to claim "It appears that p" only if it is reasonable for H to believe that, given her cognitive faculties and the use she has made of them, if p were not the case, s would likely be different than it is in some way discernible by her.
