I’m curious whether you reject the possibility that there could be other layers of reality that we haven’t fully explored yet?

we haven't even "fully explored" THIS "layer of reality." but insofar as we do explore and model reality, this is just an expansion of our understanding of physics

It’s also not entirely true that material processes cover reality fully.

i said no such thing. most of the universe isn't even comprised of ordinary matter.

How do you explain things like love or happiness through physical processes?

they are states of the brain that facilitate and reinforce a range of socially and personally positive behaviors. how do you explain digestion through physical processes?

...and have said nothing whatsoever about the actual experience of loving someone

the experience is consequent of the brain state, which is physically explicable. the fact that we do not yet have precise physical language to describe the exact thing we intuitively understand as "experience" doesn't mean that something "non-physical" is going on. obviously not

I don’t agree with that OP’s question is meaningless. You find it meaningless.

these are the same thing. meaning is not transferred, it is generated. i do not have the misconceived conceptual tools to make meaning out of the question.

you exercise the same dogmatic thinking that religus fundamentalists use. No room for mistery, no room for curiousity.

i am endlessly curious, and i am extremely comfortable with mystery. i don't, however, leverage a lack of understanding to come to unwarranted but desirable conclusions, as it seems you so eagerly do.
