I wish I knew how to quote everything so I could answer more succinctly, but I don't (and these buttons are too small on my phone.)
By linear progression of consciousness I meant what becomes of consciousness after what we call death.
I won't explain how, but I have seen evidence of a living past, so let's just say I firmly believe in that, though it's a pretty well-established theory among physicists anyway, so I don't see why it so seldom pertains to discussions such as these.
I personally believe in a cosmic feedback loop where brains do produce a non-local field of consciousness that in turn creates things like brains. Outside of linear time it's all self-sufficient.
If we're always going to think in terms of our experience, there's no way we're going to cut to the truth.
But even as simply a theory of Einstein's, there should be more thought given in such discussion to the idea that all time exists at once.
This is certainly akin to what I believe, though I readily admit I have no idea what happens to consciousness after death, but I think the two are related.
As I say, I've witnessed things that cause me to believe that the past is alive and well, and I don't know...maybe better minds can wrap theirs around what consciousness is really like in relation to a block universe.
I really do think thinking in a framework of non-linear time, despite all the inherent difficulty thereof, is the path forward. And I can vaguely see how it would be self-sufficient and incorporate both physicalism and spiritualism.
I mean, it probably is true that brains generate consciousness, but that doesn't speak to how consciousness interacts with all perceived dimensions of reality, if we're to be honest. I think they are truly timeless and generate a non-local field.
But it has been too much for me to wrap my mind around. Doesn't mean it's not the way forward, though.
