Argumentum ad populum fallacy of course, sherlock used this one, combining it with an appeal to authority fallacy as well, appealing to the intelligent philosophers who have held subjective theistic belief.
Ah one of my favourites, and how do we know there is any risk to either choice? Well well, a false dichotomy fallacy look. I think apologists and religious philosophers might do well to have “I don’t know” laminated on a card…the entire necessity of scientific endeavour is predicated on those three simple words…
It’s also begging the question, and a circular reasoning fallacy.
Argument from personal incredulity…
Begging the question…we don’t know it required a cause, this would need to be demonstrated, odd how theists seem fine and dandy that a deity needs no cause…
Argument from personal incredulity, and a false dichotomy.
By far and away the most commonly used of course are argumentum ad ignorantiam fallacies, we don’t know X, therefore god, Sherlock started with this fallacy, and used it relentlessly, even after it was explained he refused even once to address it with anything but handwaving.
For example from his first day on this forum:
It is irrational to claim anything is true, because one cannot replace it with an alternative. This is also of course a false dichotomy fallacy.
