It is your invention as a straw man to be defeated by computationalism. Some physicists and some philosophers may suppose that the stuff described by physics is enough to explain the world we observe; but most also suppose that it is not "primary". They look for a deeper more unified ur-stuff and many physicists have followed Wheeler and Tegmark in thinking of the equations of mathematical physics as simply defining the ur-stuff. Brent This and other old philosophical ideas are of no utility in physics. There is no physical meaning to terms such as primary matter. Primary matter is a metaphysical idea about the reality... so of course it is of no utility in physics... but physics don't tell us anything about what is reality.Yet it tells us about how the world works and what we can and can't do. So what exactly would it add know "what is reality". This is exactly like my point about consciousness. When we can predict, construct, manipulate, consciousness the way we do the physical world, then the "hard problem" of consciousness will be as irrelevant as elan vitale is to biology and "primary matter" is to physics.Everythingism are metaphysical idea about what is reality... so if your concern is only in utility, philosophy doesn't concern you... Materialism, physicalim, computationalism, deism etc are metaphysical, philosophical and about what reality is... physics is about prediction on the reality, not about what ultimately reality is... it answers how, not what and why... The problem is with people equating physics whith physicalism... they're not the same, one is a metaphysical idea about the nature of reality.But I'm suggesting to you that this metaphysical idea is empty if it has no consequences, but if it does have consequences then it's physics and not metaphysics.That is your point of view which I do not share... You're like people who don't like arts and find that empty... As long as you're not imposing your view, I'm fine with it.
As I am fine with those seeking the elan vitale and primary matter. Just so they don't use my tax money.
