Very difficult to have conversations at the limits of fundamental physics.
Physicists are obviously very attached to which parts of fundamental physics – and deep understanding thereof – are considered “fixed” in their firmament. And that’s true even if they appear open-minded on philosophical discussions. It’s impossible for all of us to have the same depth of understanding – or even the same kind of understanding – of all the sub-topics as conversations dot all over this map – of life, the universe and everything – for me that’s a given, the reason for the dialogue.
All too often however, you get to the “turtles all the way down” lower limit to whatever we choose to name “physics” and when you are prepared to admit you’re really talking metaphysics – and more to the point being comfortable doing it. However, when the caricature becomes
Physics= real, whereas
Metaphysics = anything goes, flights of fancy, etc.
The dialogue has ended, at least temporarily.
In metaphysics, and at the lower reaches of the physics that interface with it, the idea that objective, empirical falsifiability is the sole test of an idea is an obvious flaw. It’s about what indirect predictions, including empirically falsifiable ones higher-up in the observable stack, can create the best, most consistent stack with the least reasons to doubt, the best reasons to take as true. The best chances of fixing existing problems, the least chances of introducing new ones. I mentioned this in the previous post – Whitehead and Wittgenstein at the very least. Even within the canon of accepted physical science, there are many methods and processes for assessing truth and validity other than direct falsification: Bayes, Occam, etc.
Choosing a single test is fine as a boundary condition – a working definition – for any given discourse, but is ideology if it is seen to set a fundamental limit on what things exist in reality.
