I got tired of waiting for a response from Malerin in
this thread to the question, so thought I'd open it up.
Well, I consider myself as being a phenomenologist rather than an "idealist" but my response to this would be that it's not really up to non-materialists/non-physicalists to define the terms that materialists/physicalists use.
However since I see you have provided your own answer in the following that point may be moot.
Historically speaking, materialists might well have only regarded existence in terms of particles and their interactions. As the nature of particle interactions, fields, energy, information etc. has become better understood, we've adjusted that understanding to define the universe less as an interaction of particles, and more as an expression of information according to deeper laws or rules. Thus 'physical' refers to the interaction of information that gives rise to properties which can be observed. Unfortunately the limit lies with the question of 'what is the fundamental property of information?', which is akin to asking 'what is reality made of?'.
Yes.... and very good!
But, of course, the devil is in the details.
The word 'physical' (or physicalism) is and outgrowth of 'material' (or materialism) - and these are, I strongly suspect, every bit as loaded concepts for many people as words such as "Soul" or "God".
(This is part of the reason why I just refer to
things, in more neutral terms as "objective phenomena" or "subjective phenomena" - or, on occasion, phenomena and neumena.)
Historically, when the theory of matter was constructed in ancient Greece by such individuals as Leucippus and Democritus it was taken to mean some “substance” or other that is ultimately underlying all of objective reality.
This idea of some, ultimate, fundamental "substance" or other underlying all of objective reality was
extremely important to the theory as it contrasted it sharply with the standard forms of vitalism and animism that held sway in the ancient world.
Several thousand years later and, to scientists at least, the idea of substance has been replaced with the word 'information' in the exact same sense that you apply it yourself.
The problem as I see it is that this neutral term "information" only serves to smother the blow by only describing the situation rather than explaining the situation - the profoundity of which is hard to fully appreciate:
We live in a universe in which only two things actually exist - consciousness and information. Yet -
and here's the real kicker objects do indeed continue to exist even when we're not looking at them or thinking about them.
However, I am beginning to stray from your original question.
My issue with the words "physical" and "material" is that they come with a past. They come loaded with the concept of a neat mechanical, orderly Universe with some type of fundamental
prima materia substance underlying it.
One doesn't have to look very hard online or offline to find a definition of “matter” that includes the word “substance” and I very much doubt the average man on the street would think it means anything other than this.
Consider, if I were to say that all I meant by "God" was:
that which underlies objective reality and is ultimately responsible for our counsciousness (and, by extension, ultimately subjective reality also), the laws of the Universe, the information therein and all the properties said information gives rise to would you be happy to have this very fair, and frankly untheistic, use of the term replace all instances of matter and physical in any given science text book?
I very much doubt it. And is it not obvious that the reason for this would be the connotations that the word "God" brings with it?
I think we would all be better off replacing physical/material (laws, objects, etc.,) with phenomenal/neumenal (laws, objects, etc.,).
Idealists seem to allude to there being the possibility of something other than that which is 'physical' (as a philosophy distinct from physicalism). I'm wanting to know how they define the word 'physical' if it does not relate to an interaction of information according to a set of rules or laws.

I don't know what idealists do but that's not the case for me. My only question is what is the most parsimonious solution to the situation as we find it?
To that end I see two possible candidates with the ability to store information - some self-generating/sustaining substance or other (prima materia) or some kind of overmind (God).
We have no objective proof of either - yet, clearly, evidence for one would instantly falsify the other.
So just
what is the most parsimonious solution to the situation as we find it?
Well, to my mind, even though both (prima materia versus God) are both valid and testable (in principle if not in practice) theories, the God theory clearly has the edge for the very simple reason that we already know that consciousness and/or mind exists while we have no evidence for any substance of any kind.
That certainly doesn't prove God exists but it definitely does make it more parsiminous. Theists are only theorising the existence of another (bigger) consciousness (one step) while adherents to the alternative theory have to imagine that there is some secret hidden substance underlying reality based on....
absolutely nothing (two steps).
In short, there is no multiplications of unknowns in theism since consciousness/mind is known to exist.
All the best,
