Do you have evidence that history research is universally consciously methodological naturalistic?
Surely history would be identical to science and therefore able to eliminate itself since it is by definition the study of unrepeatable events.
No, it would not be identical. In part your problem is you have become confused between a definition of science, and one that is wrong to start with, and methodological naturalism. They are not one and the same thing.
Let's first deal with your misunderstanding of the question of unrepeatable events here. In an absolute sense all events are unrepeatable and indeed unique. Were one to use your specious idea that unique events were supernatural then every event is by that definition. The use of repetition in science refers to experimentation and not about whether the actual event is repeated.
To move onto history, methodological naturalism simply assumes that we can investigate using probabilistic techniques (something impossible in a supernatural claim since it breaks the normal assumption of cause and effect in methodological naturalistic disciplines). In order to evaluate claims of the supernatural it would need some form of method to do that. You know like the one you have been asked for so many tines but gave never supplied.
As to do I have evidence that history is universally naturalistic in method,note I have no idea what your addituon of 'consciously' means in the context, the answer is no but since that's a strawman irrelevant. As already noted BA talked about using historical studies to establish the truth of supernatural claims in the NT. In the number if universities in the UK that I have been involved with on the study of history they have been entirely naturalistic in method. In terms of the number of people I know currently teaching history at university, they all teach it in a naturalistic manner. So what I was asking BA was to back up his claim of having studied history in a way that is not methodologically naturalistic. Despite asking, nothing so far.
So now that I've clarified the matter, do you know of any such teaching in a recognised UK university course that does this?
