I'd like the discussion to occur in the context of a specific question, namely, "Is the Book of Mormon an actual record of and by inhabitants of the Americas ." (I'm not wedded to that wording at all, but I suspect you get the basic idea)
I'm going to suggest two different ways we could think about evidence in this context:
1. For any proposed fact, we engage in a two-step analysis. First, using some definition or test, we determine whether that fact constitutes evidence at all. If it doesn't, we don't consider it at all. If it does, we try and determine how much weight to put on that evidence (i.e., figure out how relatively strong or weak it is).
2. Skip the part about deciding whether the fact is evidence and talk only about the weight.
Finally, i'm going to propose borrowing from legal concepts to define evidence. This is from the Federal Rules of Evidence 401:
Evidence is relevant if:
(a) it has any tendency to make a fact more or less probable than it would be without the evidence; and
(b) the fact is of consequence in determining the action.
The rules distinguish between "relevant evidence" and "irrelevant evidence," which I think is functionally the same as the distinction I raise between "evidence" and "not evidence" I'd be happy to use either terminology.
So my initial question: option 1, option 2 or something else. And why?
