Hey Vox Humana, it is nice to discuss this with you. You post arguments, and don't appeal to emotions, commit strawmans or babble at all. I appreciate that.
It can be, just not nearly so succinctly. The idea of material substance is a useful abstraction that:
- Accurately models the reality we perceive.
- Allows us to communicate efficiently.
I have issues against 1, "models reality" it works as a map, but only at a perceptual level (as you point out) when we dig beyond what our senses can see or touch or smell, we have to deal with different "things". I believe it is naive to call such "things" as material. As I have said:
For convenience we can say that reality is physical, made of quarks, quantum states, strong and weak forces, and so on. But we must never forget that such concepts are oversimplifications that serve a purpose (they are like anchors that let us to make predictions) but arguably they are not “real entities in themselves”. Particles and waves are ways of describing reality, nothing else, and nothing more.
Yes, it is useful, I agree with your point 2. I have said that it makes us feel comfortable. Still, I believe its utility should be limited to the everyday life. IMO, both science and philosophy certainly don't need it for anything.
In my prior quote, I noted that the two statements:
- X is Y
- X exhibits a set of properties and behaviors
are equivalent if we define Y as the set of properties and behaviors. That's all we're doing here.
They are not equivalent, you are stating this (on the second one) "X exhibits S of P and B", there is not a relation of identity anymore but a description.
I don't think that this is what's happening, though - at least not for me, and I would posit not for most people in general. You've presented two ideas of the nature of substance:
- Immaterial, or spiritual substance
- Material, or physical substance
For grins, I'll add a third:
- Simulated substance
(Please enlighten me if these ideas have proper names, I'd like to know.)
I'm not indicated to state it, my example was merely to understand why some materialists claim what they claim. I have clearly stated that I have no intentions whatsoever of proposing an "alternate theory" much less any kind of substance.
All three ideas fit the models we've developed and tested for our reality, it's just that the last is the simplest, makes the fewest assumptions and leaves out the extraneous details.
Agreed. Now, it is even simpler to leave out ANY assumption regarding "the ultimate component or nature or whatever" about reality. Uttering the words "it is material" is not valuable, unless it is used for the everyday life, like when we state that "the sun rises every morning".
I argue that the only one adding another element is the one who claims "substance is spiritual". The one who says "substance is physical" is really saying "substance is", nothing more.
I have followed your argument, it might be good, but I don't think it resolves it, we get back to the "X
is Y" formula that I claim is not needed. Now, your depition of it SURE WORKS, but the statements naive materialists bring all the time to the discussions, DO NOT.
Is your objection to the material "final substance" that it excludes the possibility of a supernatural reality?
NOT AT ALL!!
