This does not follow. The universe could be completely deterministic, and we would still have free will and be making choices. Interesting that in a completely deterministic universe our choices would be simply a illusion. But those choices would be an illusion...

I guess we understand different things by the phrase "completely deterministic"...
Well, no, it didn't. It could be predicted with total knowledge, but that's not quite the same thing. And that ability to predict has no baring on whether or not we have free will. It makes it an illusion! You're not really really making any choice at all. In Message 17 you wrote:
We have free will if our actions cannot be predicted without knowledge of our internal state. We choose because our nervous systems are responsible for our actions. It matters not a jot whether those nervous systems are deterministic or not. Predictive ability doesn't really matter. If the outcome of the action of your nervous system is pre-determined by the condtions leading up to it, then you're not really making any choices, even if there's an illusion set-up that makes it look and feel like you are.

Have you seen the experiment with the green dot that changes red as it flys across the screen and the people seeing the red dot before it even gets there and before its even red... or somethign like that?
I can't seem to google it up because I can't remember enough about it. You know what I'm talking about?

Of course you're still making choices, why wouldn't you be? You are not really making the choice if its pre-determnined, its just an illusion that you're actually making a choice.
I can write a computer program that makes choices. If its "completely determined", then you the programmer will decide what choice the computer makes, not the computer itself.

No, I decide what choices it can make not what choices it will make. That's not "completely deterministic".
In fact, I could go further and write a completely deterministic program that makes choices I don't know what are but that's by the by. I call shenanigans.

Yes, it is. The response depends on the inputs. That's only partially deterministic.
Consider a chess playing AI, I would determine how it chooses it moves but not how it would respond to a particular move from its opponent. That's not completely deterministic.
Any learning algorithm will do this. That's not completely deterministic.

Given that it seems blindingly obvious that a system that works by obeying a set of unwavering rules is wholly deterministic, you can't just say "it's not" without explaining why. Well, he's just saying it is without explaining why, and you're just saying its blindingly obvious without saying why. If the decision are not determined in the programming of how it chooses, then its not completely deterministic. If it is completely deterministic, then its going to make the same move for each input and therefore its isn't really making the decision itself.

'Programming' and 'inputs' are basically the same thing.
The programming is the determination of how it chooses its moves, the input is the move that the opponent made.
They both affect future decisions. Indeed.
If you reset the AI and give it the same programming and inputs: you will get the same decisions. Time after time. Then its not actually making a decision.

I see the attraction to the idea that if evolution has an objective then there must be some entity with the ability to hold an objective. Evolution does not have an objective any more than gravity has an objective. Shit just happens.
Am I conflating ‘objective’ with ‘direction’? Regarding a direction, I'd say that evolution sort of does have a direction... I guess I'd call that direction "outwards". It seems to me that every niche that life can fill, it does. Its always, inadvertantly, trying to expand as far and wide as it can.
The process of evolution or process of the universe is rolling along and making stars and mud puddles and eventually people. We are just another product of the process that also makes mud puddles. What is it about our sentience or consciousness that is suddenly worthy of distinction from the rest of the process? Its pretty sweet that an aspect of the universe is recognizing itself as an aspect of the universe... We're the only thing I'm aware of that can do that.
It appears that many consider our perceived ability to make choices to be the distinguishing element. But not just humans, right? Other animals too, no?
But why does that ability merit considering ourselves to be separate or unique in the universe? Doesn’t our awareness actually belong to the universe? Is it wrong to say that the universe itself is aware? Not the universe, itself as a whole, no. But if you want to call our consciousness a part of the universe, then yes. As they say:
quote: It seems odd to me that the question immediately goes to the differences between idealism and realism, a deterministic universe or not. I do see why it goes there but why is the distinction made? I am content to talk about free-will as it seems somehow fundamental and I am not convinced that I actually have it. If the universe is completely deterministic, then there's definately nothing special about our consciousnesses and ability to make choices that can in turn affect the universe and "change the path", so to speak, because none of that is really actually happening its just that it seems like it is to us.
I guess in the end I am questioning why the Eastern philosophy of oneness should not be taken as the one that is most reasonable. I have, for a long time, considered myself to be a distinct entity but is that a supportable position? I, as in me, am not just the some of my parts. There's something else there. The universe is not completely deterministic, and we are special entities.

I was thinking that the direction (objective?) of evolution might be to evolve an entity that is ultimately fit. Immune to death. If such an entity were to evolve would it's evolution then cease? Maybe, if it's evolution had become self controlled. An immortal species could still evolve via pressure from sexual selection.
Yeah, I see that. Does this lend credence to the idea that 'The devil made me do it'? No judge that I ever talked to would buy that. It does, but too, the devil made us throw your ass in jail
I think that this is at the root of religion and the search for GOD. Why would we be scratching if it doesn't itch? I suppose there could be an evolutionary advantage to having itches that aren't really there *shrugs*
The universe is not completely deterministic, and we are special entities. I don't see how you get to that conclusion. Some things aren't deterministic, like Brownian Motion or radioactive decay. So if we really are making choices then that makes us special (imo).

If the outcome is independent of our "choice", then we're not really choosing and we don't have free will, but if the outcome does depend on our choice then we do.
This isn't a very complicated concept. Brownian motion is deterministic Oh, I get it:

I agree. Why do you imagine that determinism interferes with this concept? It makes the outcome independent of our "choice".
so the overall motion of the visible particle is deterministic If you rewind and replay, will the particles follow the same paths?

Huh? How would it do that? It makes the outcome independent of our "choice". Your "choice" cannot change the outcome.
I'm not aware that you can rewind and replay reality, From Message 72:
quote: Quit playin'... Don't you realize that you are using the word "choice", and possibly even the word "determinism", differently than everyone who is arguing with you in this thread?
but given the same initial conditions you'd get the same outcome, just as you would with billiard balls. How do you know?

Maybe this is just a semantic argument, but I think we're looking at this in different ways. No shit!
The outcome isn't independent of your choice if your choice is predetermined. The outcome is the result of your choice, the point is just that your choice is the result of other factors. I get it, but that's not what people are talking about here when they are using the word "choice", and that the above is what is the illusion of choice.
If the choice is not predetermined, how is this in any way more simialr to what we mean when we say 'choice'. Something not dependent on its causes is essentially random, isn't it? No, its free will. Its up to us what the outcome is, that's what poeple mean by "choice". Its not random, but you can't predict the choice from the condition. That's what makes it an actual choice instead of an illusion.
I don't know if quantum mechanics change our understanding of this, but in classical physics - yes, that's exactly what would happen. Chaotic systems will behave in exactly the same way from identical starting conditions. Brownian Motion is a stoichastic process and that means that they will *not* behave in exactly the same way from identical starting condition.
