I get the feeling that predetermination means, to you, that if I am
predetermined to choose to buy this house (say), then no matter what I
think, or even if I don't think at all, I will end up deciding to buy
that house. I could move to Tibet, scramble my brain with acid, and
spend all my conscious time playing Candy Crush, and still, in a day or
two, the though will come to me, "I need to buy that house."

That's not how predeterminism works. In a predetermined world, I find
myself in need or want of a house, contact a realtor who shows me
available listings; I visit those houses which are in good price range
and neighborhoods; probably I am influenced by external factors such as
the amount of traffic I had to fight through to get there or how hungry
I am at the time. The good and bad points of the different houses being
fed into my mind, I eliminate some obvious non-candidates, and let my
gut guide me to the best of the remaining.

That is predetermination at work.  Note that it appears, to all
observers, exactly the same as non-predetermination. That's why the Free
Will issue has never been resolved.

So, if I'm understanding that correctly, there is no
difference between determinism and non-determinism (or if
you prefer, determination and non-determination), and
therefore "free will" is a bugaboo which is not accepted
although its implications are?

>
No detectable difference between the two. And I should have added "free
will" is also wrapped up in religious, personal angst, and equivocation
issues, which also contribute to making it a bugaboo.

OK. I'd point out that the fact that the concept of free
will is "wrapped up in religious, personal angst, and
equivocation issues" doesn't make it false.

My position is not that it is false, but that it is effectively meaningless.

And that one
possible reason why there's no detectable difference is that
we have no way to detect the operation of free will in
itself.

I have given some thought to how, even in theory and with advanced
technology, one might detect free will, and I have come up empty. Some
Star-Trek-like parallel universe thought experiments could conceivably
determine whether the universe was deterministic or not, but even if
not, that only rules out determinism, not the lack of free will.

Yep. I've done the same, although not in any great depth,
and come to the same conclusion; the closest I've come is
something like, "Well, the probabilistic nature of base
reality *seems* to leave room for something resembling
choice, but as for testing it...".

>
Hmm, what could this "something resembling choice" be, other than
something 'outside' reality (ie supernatural) that somehow (magic?)
overrides the "probabilistic nature of base reality"?
>

You might want to re-read what I actually wrote, which was
not that anything is "outside reality". Reality, at base, is
probabilistic, not "clockwork".

It's sometimes amusing to
discuss such things as determinism vs. free will, or the
number of angels which can occupy a pin point, but it
becomes boring fairly quickly due to the lack of any way,
even conceptually, to determine the answer. Which, as I
noted below, brings it down to a matter of belief in the
validity of personal experience.

My, somewhat vague and evolving, view is that it feels like I experience
'qualia' and 'make choices' between alternatives and that I am not
special, so others who report the same are not philosophical zombies
deterministically lying to me. It is a 'real thing'. I see two
possibilities. There is some unknown, evidenced phenomenon unrelated to
known physics somehow related to some minimal level of complexity of
life (dualism/free will) or a, actual activity unknown, manifestation of
physical brain activity (determinism). What leads me to believe the
second is more likely is the indirect evidence. Alteration of brain
activity (physical damage, drugs,etc) causes changes in peoples'
reported qualia and changes in (historically expected) personality and
range of choices made. This is usually observable with major changes to
the brain producing major changes in personality and/or range of
choices.but I think it not an unreasonable extrapolation to minor
changes in the brain (caused by minor changes in the environment) to
cause minor changes in experience/choices due to the same mechanisms.

Your friend George is picking new wallpaper for his living room. Knowing
your friend and his living room, you think he will likely pick something
off white with a small floral motif in blue.
You visit and see he chose pale yellow with thin blue striping. You are
not surprised by this and on discussing it with him he states he was
considering something like what you were thinking but this one really
struck him when he saw it in the store.
Or
You visit him and see he chose a vibrant, primary coloured geometric
zig-zag pattern. You think 'was he on drugs? / dropped on his head?' not
'hmm, how unusual'.

So, what is the sourcr of the phenomena we often descibe as 'dualiy'
and/or 'free will? We may never know but my personal belief, based on
the evidence I have, is that it is almost certainly due to some kind of
phyical activity, most likely in the brain (in humans and our close
relatives).

Testimony, of course, is irrelevant, since it may
itself be deterministic. I do see the problem, which comes
down to whether to accept of the validity of personal
experience. I happen to choose (there's that word again...)
to do so.
