So let me ask you...
If quantum physics is a thing that evades our everyday intuitions and for which we've had to develop special tools & math to gingerly describe...how exactly is 'ultimate reality' being studied?
English is not made out of math, to the best of my knowledge. Can we actually talk about the world using words instead of numbers?
You see, the problem with words is that you kind of have to assume that they work as intended before you start using them, and any attempt to use words to investigate the world will therefore have this confirmation bias built into it. Notice how you're talking about reality as if you can actually
talk about reality.
This assumption is kind of important when you stop to consider that civilisation basically boils down to a massive attemtpt to have everybody
live according to the word. In this respect, the architecture of the word (i.e. grammar) will have an unavoidably profound effect on the way a civilisation expresses itself. In the case of Christianity, the myth has God speaking the world into creation with the word(logos), and Jesus conveniently happens to be the incarnation of this word that was used to speak creation into being, and every living person is an image bearer of the divine thus deserving of dignity no matter how low their station might be.
That creates a different kind of civilisation to a civilisation that holds words to be meaningless air vibrations, to be measured only in terms of their utility, and what's the big deal with expunging a couple of humans for the sake of the greater good because consciousness is only a damn epiphenomenon anyways.
Have you considered the price you have to pay for admitting that we all just make it up as we go along, each of us starting locally and reaching outward?
Does the metaphysician believe ultimate reality is more available to intuition and description than quantum theory?
That would depend on the metaphysician, I suppose.
Do they believe knowledge of ultimate reality is arrived at by just thinking about it?
Clasically speaking, yup. It gets a bit less clear after Kant and his Prolegomena to Any Future Metaphysics.
