I'm simply asking you if you believe that a major portion of the subject matter of physics is something that's not physical. And the answer is?Skepdick wrote: ↑Mon Jan 18, 2021 12:58 pmWhatever physics deals with it would be the same kind of stuff irrespective of the label you put on it.Terrapin Station wrote: ↑Mon Jan 18, 2021 12:26 pm I should have brought this up when you first mentioned it, by the way, but were you thinking that insofar as physics deals with energy, it's dealing with something that's not physical?
I didn't bring that up at first because I find the notion of energy occurring on its own incoherent, and that's more interesting to me.
The nature of things doesn't change in any way just because we re-describe them. It would be stupid if it did.
Physics deals with symmetries and structures, so the Mathematical equations used to describe physics would be exactly the same even if energy was non-physical.
Underneath molecules are atoms.
Underneath atoms are quarks, leptons and gluons.
Underneath quarks, leptons and gluons there's nothing.
Those things can only be understood in terms of Mathematics.
(By the way, not that I agree with this, but a common characterization of physicalism is that it posits that ontology is (or at least will be or theoretically could be) exhausted by physics.)
