Do you think quarks cause blood to clot - does that make sense to you?
Ultimately, yes.
If quarks didn't operate the way the do, atoms would not form. No atoms no blood.
A cause doesn't have to be a
direct link.
Like erosion. River valleys are
ultimately caused by oceanic evaporation. There's a lot of steps in between, sure, but no evaporation = no air moisture = no rain.
Or the biochemical states they created - that would make more sense.
Sure, but those patterns that created the-biochemical-states-that-we-created were
created by the biochemical states.
The states are, as you say, the substrate. No biochemical states
in the first place = no patterns = no states created
by patterns.
Another analogy: Conway's Game of Life. It could, in theory, create some fabulously complex, inter-functionally-looping structures - replete with constructs that detect states and storage units. But nothing can come from it - no patterns can be made - that the rules of the game board do not permit. Those fabulously complex inter-functionally looping structures cannot attain any kind of decision-making that
transcends the deterministic nature of the states of all the cells.
It may
look like it can, because it's so complex - but ultimately, one could erase the whole board, set it back to its initial conditions - and the exact same structure will be created - and it will repeat the exact same "decisions".
Even if you throw in a randomizing monkey-wrench - one that occasionally mis-copies the state of a cell or two - that's
still not the Game having a will. That's just the same determined structure-and-flow with some uncontrolled elements thrown in.
So you are positing an illusion without an observer.
No.
You said:
"...clearly the observer and the illusion would have to be separate entities, no?"
Why would they have to be separate? We do not have access to the processes that shape our thoughts and perceptions. We only observe the end result.
This is why, for example, we can't fully trust our vision, or our memories.
