"Agreed. Remember I'm the one that keeps saying it's the changing configuration of what is, that turns future into past. Potential into residual."
Does it, though, John? If a brain-mind process linearly orders events into memories, how does one actually know "what is"? All the nonlinear events both within and outside a brain-mind still exist in a continuous state of chaos. Is "what is" only what one's brain-mind configures, or is it the aggregate of events both within and without, with no objective distinction between past and future?
That's the central question of realism. Beyond the naive version of realism, where brain-mind perception is identical to "what is", an objective realism in terms of quantum mechanics (the Bell's theorem version) is localized by a measurement event; events cannot be "real" until measured and are otherwise in a linear superposition of states and nonlocal. This is what creates the distinction between past and future events.
Such a distinction in classical physics is arbitrary; all the laws, all the equations, of classical physics work just as well backward or forward. The future is just as real as the past -- it isn't "somewhere else out there," because the determinism of nonlinearly evolving states is indifferent to the arrow of time. George Ellis' comment, that " ... without an arrow of time, there is no life" is poignant, because it acknowledges the role of consciousness in the linear order of events. By the conventional interpretations of quantum theory, we take this to be foundational.
One of the several things that makes Joy Christian's research revolutionary and important, is that it recognizes linear order is *not* foundational -- that the objective world is independent of the consciousness that orders it into past memories distinct from future events -- *yet* -- external nature *and* our brain-minds possess an identical degree of randomness. Nonlinear evolution explains why artificial computer programs remain inferior to any brain-mind process. A computer cannot calculate backward in time; a brain-mind can.
(me, previously)'A true realist perspective, I think, would recognize that what makes the world objective actually *necessitates* the determinism of random nonlinear input.'
"Is it determined prior, or post input? If prior, how? As I see it, the lightcone of input is only completed by the event and it is what happens then that determines the result. Potential into residual."
That is the conventional view of quantum theory that assumes an observer-created reality. I consider that anti-realist -- Anton Zeilinger is a main proponent of anti-realism.
"Doesn't the process of input and output qualify as a somewhat linear process?"
Not necessarily.
"It should be noted that the sequential process of input and output applies to our physical interaction with our context and it is quite difficult to think and act non-linearly."
In fact, it may be impossible. ("Without an arrow of time, there is no life.")
"We don't do super-position, without it getting a bit schizophrenic. It's context, the environment, that is non-linear, because it is just a lot of counter-balancing actions."
Superposition and nonlocality are illusions in a fully deterministic environment.
All best,
