I actually don't mind labels much. As in, you can be a total idealist and say that we create the world with our minds. Or you can be a metaphysical dualist. If the arguments are interesting and persuasive, that's what matters. I only dismiss "eliminitative materalism", because it's just very poor philosophy.
Hmmm, I can see that argument. I think we agree that we have to consider sensations and intellect as different but closely inter-related "modalities" or "faculties", for lack of a better term. It could be that brains evolve prior to sense, it's possible.
Perhaps at some point "down the system" these things actually converge, in very primitive organisms but then they develop differently. The one thing that keeps coming to mind is that sense alone, is poor when compared to the intellect alone, in as much as we can separate them in actuality.
Oofff. Gets really complex here. I don't know how to express "here" mathematically. I guess if you add something in relation to you, say a Capital or mountain, then yes. But with nothing else to go on, over here is hard.
"There" can be expressed mathematically in so far as you have an object in mind which you can express in measurable units, as in, the Moon is 384,000 kilometers away from the Earth. But we remove here all phenomenal properties by saying this as a fact about the world.
Yeah. That's the elephant in the room. Didn't want to say this because then I'm put in a position of having to defend the existence of an external world, which I think should be taken for granted. But, it turns out, it needs a minimum of justification too.
While what you say is true, I assume that for reasons we don't know, these mathematical relations do hold to the extra mental world, such that it is true that there was a world 6 billion years ago and a "Big Bang" 13.8 billion years ago, not
completely dependent on human beings.
