If the decisions made by a sentient being are
1) not random (in the quantum-mechanical sense), and
2) not a result of external influences, ie. not predictable
because the decisions are being made in a closed system rather than as a
consequence of the entire universe, then one could consider that sentient
being as having a will of its own, with choices which are not just a direct
consequence of external events, and this without necessarily having to
ascend above physics. (But, as I said, I'm not sure if this would break
some laws of physics regarding closed systems and what they can do.)
Of course if we examine the decisions from *inside* this closed system,
then we might find out that it is still completely bound to deterministic
and random consequences. However, from the *outside* it may be exactly as
if it was a being having true unbounded free will. (In other words, from
the outside it's impossible say whether the decisions are being done by
supernatural or natural means.)
This would make the sentient being different from a rock, which does
not have such an internal closed decision-making system.
This might be somewhat similar to what you already wrote in some of your
replies, and maybe this is just your point sinking in.

I didn't really require for free choice to be supernatural. I only required
that it must not be bound to previous events nor randomness (else it wouldn't
really be free choice at all).
If a closed system I described is physically possible, then (I think) it
would perfectly *emulate* supernatural free will, even if it isn't really.

Wouldn't it be a closed system if the internal decision process is
impossible to observe from the outside, no matter what kind of stimulus
is being applied? In other words, the responses are completely unpredictable,
without necessarily being random (in the quantum-mechanical sense).
