I think you are being purposefully disingenuous here. Didn't we just have a discussion on thinking critically? We can and should make a distinction between the objective reality that constitutes the grouping of atoms labeled "Billie Eilish" and any fiction that may be imagined regarding her.
Why, the group of atoms called Billie Eilish mean nothing at all to me. They house and generate the metaphysical being that has then generated the creative myth that does matter to me (but that's as much because of me, as it is because of her). But the atoms themselves mean nothing in and of themselves. So why should I care in the least about them?
No, that is not what is being asserted. It is a matter of asserting what they are, and consequently what they then are not.
I couldn't care less what they are. And on a quantum level none of us even knows what they are. I don't understand this weird obsession with a materiality that has no significant meaning and no one really knows, anyway.
An atom of the element carbon exists, but in that configuration of mass/energy it is not an atom of the element boron or lead. It is appropriate and reasonable to make such distinctions.
To a biochemist, sure, but to the rest of us, no; it's not reasonable. Each of us is far, far more than the biochemistry that's involved in our happening. And in fact, without that "more" part, the biochemistry is of no consequence at all. Without the amazing thoughts produced, the human brain is just a pile of biological waste.
In the same way, it is more than appropriate to distinguish between the manner in which I exist in the real world and the manner in which Harry Potter, the fictional storybook character, exists in the real world.
But that's just is. No one around here ever bothers to distinguish between "the manners of existing". Most won't even acknowledge that there is such a thing. It's why the discussions/debates never go anywhere but spiral into the abyss of 'tit-for-tat' personal attacks.
You are fighting against anyone's attempt to make such distinctions. Why might that be? What purpose does it serve?
I'm the one trying to get people to make distinctions. But their bias is based on their ignorance of those distinctions, and so they don't want to make distinctions. I try to point out the difference between any one person's concept of God, and the idea of God as a collective universal concept. But nothing doing! They want to fight about THAT God. Or whine about too many different gods. Because that serves their bias.
Here it is then. The source of your fear and why you vehemently oppose demarcation.
I am not afraid and I do not oppose "demarcation".
I am not convinced that self-deception on the nature of pure abstraction is required for pure abstractions to be useful.
At some point "self-deception" becomes an irrelevant factor. Everything going on inside our heads is a form of self-deception. Yet it's still going on, there, so it's still "real". Therefor, reality is a deception. And since it's all going on inside of 'us', it's all self-deception.
But it's all we've got. So even though it is a deception, we struggle to try and keep it as 'real' as we can (whatever that even means in this instance). And this is where everyone is getting confused, and their bias is developing, and then working hard to maintain itself. Causing even more confusion.
I think the only way through it is to stop believing stuff. Let it all just become information and then focus on what applies in the moment, leaving the rest aside for another day. But that's not how most people think. They want to nail everything down, and label it true or false, and then walk away with the comforting pretense of certainty and righteousness.
You will have to prove to me that there are conditions that necessarily require the self-deception of treating an abstraction pointing to a fiction as to instead be pointing to a non-fictional phenomena or event.
IT'S ALL FICTION to us. AND it's all real. What you want isn't there. The black-white, right-wrong, real-unreal, abstract-obective, dualist existence; isn't available. Existence is all one huge complex event, happening. Those dualities are only in our heads.
Not sure how that would be done as it obviously acknowledges the self-deception. Seems like we would be wading deep into "Double Think" territory as described in George Orwell's book "1984".
"Double-think" could be another word for taoism. "When you feel the early spring sunshine on your face, and you smell the wet earth bursting with new life beneath your feet, remember the fall, and that dry and crusty sound of death and decay. And then the winter, with it's biting cold and frozen ground. Because it's within and among all of these that the Tao sings it's eternal song."
Doesn't mean we can't recognize and acknowledge that they are purely abstract constructs, and not abstractions referencing phenomena or events independent of or from abstraction.
All thought is an abstraction of experience.
Perception is conception. Let's acknowledge that, first. Then we can try to understand the degrees or levels of abstraction, and the ways we can use these to better understand ourselves in our experience of the world. Let's stop pretending that the world is a "thing", and start recognizing that it's an event, happening. And for us, it's all cognitive.
NOT MATERIAL.
