Then we need something ontologically richer than physics
to explain experience, not something onotologically
stripped-down (physics without substance).

Substance is mass-energy, and it still exists
as such in current physics.

Huh ? They have non-zero mass-energy. That's all
physicists need. Was that a solipsist's "proved" ?

Looks like it was

IOW, having assumed solipsism, you can find no way out of it.

Well, you can: you can assume the Platonic existence of numbers,
even though numbers as such don't feature in your experience.

But if you are entitled to do that to find a way out
of solipsism, the materialist is entitled to assume matter.

(Or even posit substance as necessary to explain the phenomenal flow
of time, as Kant did).

Some kinds of non-mathematical stuff are needed to resolve
the HP problem, to explain time, to explain phenomenality
and so on. The point is to posit enough to explain the universe
as we experience it and then stop.

I'm not one of them.

There is no basis for saying that whatosever.
Only living organisms feel pains, and organisms
are material.

So can you give the mathematical formula for the colour
purple, or the taste of honey ? Of course not!

The mind-body problem boils down to reconciling phenomenality with
mathematical* descriptions, not with matter pre se!

Consciousness is a problem for all forms of materialism and physicalism
to some extent, but it is possible to discern where the problem is
particularly acute. There is no great problem with the idea that matter
considered as a bare substrate can have mental properities. Any
inability to have mental proeprties would itslef be a property and
therefore be inconsistent with the bareness of a bare substrate. The
"subjectity" of consciouss states, often treated as "inherent" boils
down to a problem of communicating one's qualia -- how one feesl, how
things seem. Thus it is not truly inherent but depends on the means of
communication being used. Feelings and seemings can be more readily
communicated in artistic, poetice language, and least readily in
scientifi technical language. Since the harder, more technical a
science is, the more mathematical it is, the communication problem is
at its most acute in a purely mathematical langauge. Thus the problem
with physicalism is not its posit of matter (as a bare substrate) but
its other posit, that all properties are phycial. Since physics is
mathematical, that amounts to the claim that all properties are
mathematical (or at least mathematically describable). In making the
transition from a physicalist world-view to a mathematical one, the
concept of a material substrate is abandoned (although it was never a
problem for consciousness) and the posit of mathematical properties
becomes, which is a problem for consciousness becomes extreme.

It means the substrate of properties, contingent existence, endurance
through time, and hence real change, unactualised potential and causal
interaction.
