Atheism

[LadyForCamus]

A mistake of category, is a semantic or ontological error in which things belonging to a particular category are presented as if they belong to a different category,[1] or, alternatively, a property is ascribed to a thing that could not possibly have that property

As I said above, if you are defining the ‘supernatural’ as the inverse of ‘natural’, ascribing it the property of ‘able to be evidenced’ is an error.  You cannot have evidence of a thing that is not able to be in evidence. The natural world is evident to us, which is why we are able to collect evidence about it.  If the supernatural is “not-natural” then it can’t be evident.

OTOH, as I said above:

If you’re saying that the “supernatural” is really just an extension of the natural world, then we’re talking about a single category of things. Naturally caused things.

So, that wouldn’t be a category mistake. 

In that case, we can expect some physical evidence for these extra-natural...(?) causes, and correctly apply our evidentiary hierarchy to draw reasonable conclusions about those claims.  Unfortunately though, you’re still faced with the problem that an alleged “extra-natural” event like the virgin birth is a claim that contradicts an overwhelming body of high-quality, scientific evidence to the contrary. All available evidence indicates that human semen is necessary for conception. Heresy, at the very bottom of that hierarchy, certainly wouldn’t even come close to overcoming or overriding that fact.

Whether or not a category mistake is being made is going to come down to how you’re defining “supernatural”.
