"And your private language is not relevant to this discussion."

Since you've been trying to claim the right to define matter for all of us, and then philosophically force conclusions based on those definitions down our throats over our objections about how those aren't our definitions, it rather is.

Tu quoque. Your post is its own refutation. You can't insist on being the only person allowed to play definition games, and that everyone else is doing it wrong if they try because you know the definitions they are secretly using... or, rather, you can, but don't expect me to take you seriously as a result. Your thinking here is so solipsistic you appear to be just barely aware that there are other opinions, but you are not capable of engaging with them, only shouting at them to "shut up!" and then get back to the point you're trying to make regardless.

I'm not solipsistic at all... I'm using the socially established definition. I'm engaging in the 2500 year old tradition and usage of the word. I'm using the word in the same way it was used by Thales, Democritus, Bacon, Galileo, Newton, Descartes, Locke, and all scientists before the Copenhagen interpretation of quantum mechanics, and most scientists still today.

I'm using the word in the same way that most non-physicists still use it--where for instance biologists in crafting their theories assume that lifeforms obey classical materialist principles despite the findings of quantum physics that those principles are wrong.

You can't claim that I invented the definition of materialism anymore than you can claim that I invented 1+1=2.
