@Krumple,
Back on air (gasp !).
I think JLN is correct in identifying levels of discourse, one of which (the transcendental level) is "nothing to say".
From Maturna's point of view, what we are doing here equates to a form of "social dancing".
At a slightly less dismissive level, Wittgenstein might argue that what we are doing is "therapeutic". By investigating instances of
usage of a word like "reality" or "existence", we are dissipating so-called "problems" about their meaning.
And from a scientific point of view, "reality" becomes synonymous with results of experiments based on theories which predict/retrodict public/agreed observations. Insofar as a particular theory is successful in its predictions
may be thought to reflect an aspect of "reality". (I use theory in its loosest sense to include directed observation). But note that scientists are pretty cautious about their use of a word like "reality" (
famous Einstein quote skipped). They generally use terms like "standard model", or more speculatively "theory of everything" if they are alluding to the disputed "fundamental level".
My general position in all this (having engaged in scientific research) is to place myself in the Wittgenstein camp, with a certain amount of straying towards Maturana and transcendentalism as admirable attempts to think "out of the box".
