Evidence for Believing

[GrandizerII]

Going back to Marion Carroll's experience, even if we were to put aside experimentation and repeatability of observations as a means for evidence for the supernatural and just accept singular cases as evidence for a miracle, the problem is that personal experiences aren't objective assessments of what happened. When we're talking about experiences such as Marion's case, we're talking about how she perceives, interprets, recalls the event, and Marion (like any other human being) is prone to errors in memory and attention regarding some important details pertaining to what happened. So she may have misinterpreted, misattributed, misremembered, and all in light of what she already believes and biased by her already existent worldview. And unless we have a sufficient number of very similar cases that confirm her interpretation (which you reckon can never be so), we shouldn't jump the gun and conclude it was a miracle.
