It's all material? Made up of what? Atoms? Particles? Quarks? Some further abstracted cleverly-constructed construct of abstraction?!

I digress.

So, it's all material, you say? Then tell me:

What is it that is currently declaring the materiality of existence? What is it that is facilitating that experience of existence, right now?

You're onto something. It's definitely something beyond the material.

My brain, of course. Just a grey meaty blob of neurons firing away.
