You can’t escape metaphysics.
Behind every well proven truth there are unproven truths.
Things that are just taken as given.
If you successfully break the givens down and prove them well you’ve just broken them down into a new set of givens.
This process could in theory go on forever.
In practise though they are quite stubborn.
Logic is a system of connections but logic itself does not give the bits to be connected.
Science has progressed by a faith.
The faith that reality is rational.
That there will be no elements in reality incapable of a rational explanation.
This faith is unfounded until it is proven true.
It hasn’t yet been proven true because everything hasn’t been rationally explained.
This faith in the rationality of the universe is itself a metaphysical belief.
It says something universal.
If it is true there will be nothing outside of it which can be used as a comparision.
There would be no process of falsification for it.
The faith in the rationality is actually falsified by its own internal logic.
There will always be basic bits used as given data points to explain stuff.
A basic bedrock of stuff that is given.
Narratives can always be extended either further back down the narrative chain or further on up the narrative chain.
This happened then that.
That made this happen which made that happen which made this happen etc
