By the way, your argument seems to be, at an extreme, that even verbs can't exist in a materialist world. That since there is no matter that is called "running" that we can't define "running".
This is an interesting point because I've run into the strawman summary of the materialist approach to "mind" as saying "mind is equal to brain". That's no more true than claiming that a materialist says that "running is equal to legs". Of course we can define "running" (and "beauty" and "truth" and "suffering" and "feeling") in a materialist world.
I agree.
In a strictly materialist world, verbs indeed cannot exist. If you admit abstract properties, you admit something that is a property of matter, but isn't matter itself.
Logically speaking, a thing cannot be a property of itself, right? Matter has properties (weight, size, velocity), and since a thing cannot be a property of itself, those properties are cannot be matter.
(I have realized the point above only now. )
So I have to change my position. I used to think of materialism as a worldview that says only matter exists. But according to this interpretation, size, velocity, running cannot exist. Nobody would really hold this view, so it is a ridiculous interpretation.
I thought so because of the common phrase "materialism is the idea that there is only matter". According to this phrase, running indeed doesn't exist, since strictly speaking, running isn't matter. Perhaps it is "something that happens to matter"?
I will try to adress materialism as the view that matter is the only
substance. (Indeed, the materialist <-> spiritualist debate is whether there is a immaterial substance. ) Since numbers, and abstract ideas are not "substances", their existence is not negated by this definition of materialism, so it seems.
I understand your position better now, thanks. According to the interpretation of materialism as "only matter exists", feelings can indeed have no meaning. But such interpretation is absurd. Though look, here

he treats materialism similarily to the way I did.
Still seems to me that emotions are not just "concepts" and not abstract ideas but a different substance.
You don't think when those words come up people need to believe in something beyond the material (i.e. the supernatural) in order to understand them?
Gosh, immaterial doesn't equal supernatural. Zero logical link.
