Whilst we have agreed that every methodological system necessarily starts from axioms, I must have missed it when you demonstrated that this fact renders the system "self-refuting".
From a pragmatic pov, scientism can be seen as the attempt of a reductio ad absurdum: whereever applying the scientific method leaves something unexplained or unexplainable, this is the place where proponents of the "supernatural" can use and offer whatever methodology (which inevitably will suffer from the same problem every methodology suffers from, though) they may have developed. So far I haven´t seen any such method.
IOW: Without scientism (the idea that everything must be explainable by application of the scientific method) "supernaturalists" wouldn´t even know where there´s still space left for the "supernatural".
Whilst you "supernaturalists" are methodologically empty-handed, scientism does your homework for you, as well. Thus, a little bit of appreciation would be in order.
Well, so far it´s been you who made the claims, and I was the one checking whether there´s substance to them.
