Is free will possible in a deterministic universe?

"In science, most specifically quantum theory in physics, indeterminism is the belief that no event is certain and the entire outcome of anything is probabilistic." - link

re-read your quote carefully...
  • belief
  • uncertain
  • entire
  • speculative probability...
Perhaps if you look deeper into Heisenberg's Uncertainty (imprecision) Principle and apply a little Zeno logic you will find some enlightenment.

Is this intended as a rebuttal?
I only ask as you have suggested looking at an indeterministic principle that results in probability... in order to rebut the notion that probability is indeterministic?
To be clear: QM, by almost everybody's understanding (except those who still adhere to "hidden variables", is inherently probabilisting.
Or, to put it another way: indeterministic.
Go look it up yourself, and you may find actual enlightenment on the matter rather than the gumph you are trying to peddle.
No.
It is a suggestion that the issue runs deeper than you might think.
Indeterminism can only be reconciled using probability.

In other words, our incapacity to precisely determine outcomes, ( as per Heisenberg's imprecision principle) forces us to make use of probability to ascertain likely hood of those outcomes. ( is my understanding)
Am I wrong? If so how?
I would be seriously interested in what JamesR would say to the above....

And yet all describable physical phenomena - including everything describable as a cause or an effect - emerge (eventually) from a substrate of quantum interactions.
And the 2nd Law of Thermodynamics is held to be inviolable - deterministic.
And nothing in a universe that rests on quantum level interactions can do other than it must - thereby being defined as "deterministic", by the posted definitions in these threads.
And human decisions, including those leading to willful action, are macroscopic events bound by cause/effect - unable to do other than they must.

So that we have assumed a deterministic universe, for the sake of the argument, throughout, without losing anything of relevance.

You don't have a girlfriend, do you?
 
Quantum physics is deterministic, by the agreed definition posted and used here by Sarkus and Baldeee and so forth. "Cannot do other than it must". Nothing that obeys the laws of quantum physics can do other than it must.
That is not the definition of deterministic in the argument; that is the definition of what it means to be free. Determinism means determinism. A property of a deterministic system, when one understands what it means, is that there is no room to do otherwise. It doesn’t mean that if you have something with the property of not being able to do otherwise then it is deterministic.
You are only confusing the issue, and others, if you continue to push indeterministic processes (such as probabilistic ones) as being deterministic.
Everyone agreed to that months ago - myself explicitly.
Yet you are not abiding by it.
I think maybe you have overlooked some stuff - such as what a "specific outcome" is, or what you mean by a "given cause". Why not consider the example of the driver approaching a traffic light? It will help clarify matters for you.
Specific outcome as in the one observed. And what is the cause of that specific outcome from a probabilistic process rather than any other specific outcome. A probability function won’t be it, as that is just a description of the frequency of outcomes over an infinite number of replays. What actually causes one specific outcome rather than another? In a probabilistic process there is no cause, otherwise known as random, even if the outcomes adhere to some probability function.
If that is really how quantum theorists have boxed themselves in philosophically, it's a good thing we aren't doing quantum physics here - that makes no sense in this context. The "entire outcome of anything", for example, appears to be meaningless here.
Please drop this semantic nonsense. Your efforts to try to paper over your misunderstanding of what determinism is are now boring.
There are no more certain "entire outcomes" in the universe than those produced by the laws of probability - the central mechanisms of determination in our deterministic universe are described by the laws of chance. They are inescapable.
You need to distinguish between laws of chance due to subjective lack of information, and inherent probabilistic nature of the universe. The former is quite acceptable in a deterministic universe, the latter is mutually exclusive with a deterministic universe. You shouldn’t really need to be informed of this. It shouldn’t be news to you.
Yep. We all agreed to that, except maybe QQ.
He did, but is backtracking in his own inimitable way. Yet your understanding of what was agreed to is flawed.
And my deterministic universe - the one I agreed with you to assume for this entire discussion - not only "grants" that word (language erosion, again - a symptom), it features a mechanism.
Not if it relies on probabilistic nature of your “deterministic universe” (and I put it in quotes as I no longer believe you are talking about an actual deterministic universe).
Maybe you have overlooked some issues with these things you call "states".
Nope, nothing overlooked.
At several points I recall you insisting that some of them were illusions, for example - have you got past that yet?
States aren’t illusion, and I have never said they are. Your straw man. What could be illusory is how they appear to us. If they appear differently to us than they are, and specifically if they appear to offer the opposite of what they can offer, I would classify those interpretations as illusory. As already explained. Multiple times.
Pay especially careful attention to the word "prior" - you guys tend to lose track of that concept when dealing with real world examples.
There’s no losing track, but thanks for your concern. If you think we have been then it may be that you haven’t quite been keeping up. Might explain a few things.
Not at all.
When it's labeled a "premise", when it is argued from in a syllogism to reach a conclusion, and so forth, it's an assumption. (Doesn't matter what the conclusion is - could even, as so often with you guys, be a repetition of the assumption).
And all you have done so far is subsume conclusions into assumptions, or maybe taken subsequent arguments that build on the initial conclusion, seen it now stated as a premise, and cried foul, ignoring, as you tend to do, why your claim is fallacious.
That's not hard to distinguish. That's why I quoted all those examples from Sarkus and Baldeee and so forth, and pointed to the exact locations of the assumptions - so you guys could distinguish the assumptions for yourselves, with a little help.
You mean the occasions when you’ve had to reformulate arguments to make your point? Or reworded quotes to do so? Or simply taken subsequent arguments that do use them as premises, you thereby ignoring that they are themselves already conclusions.
Here, take another whack at it: See that thing labeled "P1"? It's an assumption.
And that’s a different argument, starting from the nature of a deterministic interaction. It doesn’t start with the assumption that there is no freedom in a deterministic universe, as you accuse. There is scope in that argument, specifically by questioning premise 2, to argue that a system built from deterministic interactions can be free, even if a specific interaction is not.
But instead, rather than actually seize on this to examine the question of complexity, and whether that gives rise to freedom, you once again try to use it, fallaciously, to claim an assumption of supernatural freedom. You’re obsessed with it, and can’t seem to help yourself. Every example you raise is either dishonestly altered or simply doesn’t do what you think it does.
 
And yet all describable physical phenomena - including everything describable as a cause or an effect - emerge (eventually) from a substrate of quantum interactions.
Quantum interactions are inherently indeterministic (unless one goes for the “hidden variable” interpretation) and as such their nature is excluded from the universe we are considering.
And nothing in a universe that rests on quantum level interactions can do other than it must - thereby being defined as "deterministic", by the posted definitions in these threads.
You are mixing definitions. Again, no wonder you are accusing left right and centre of “supernatural freedom” if you do that. The definition of deterministic is not “can not do other than it must”.
The conclusion reached was that in a deterministic universe one can not do other than one must, but that does not mean the definition of determinism is that. Just because a beach ball is spherical does not mean that everything spherical is a beach ball. You are simply affirming the consequent here.
Simply put: your understanding of determinism is wrong, and you are not using any definition of determinism posited here, by anyone.
And human decisions, including those leading to willful action, are macroscopic events bound by cause/effect - unable to do other than they must.
That is the conclusion, yes.
So that we have assumed a deterministic universe, for the sake of the argument, throughout, without losing anything of relevance.
Yet your understanding of the deterministic universe is wrong, you are using a definition no one has posited, and in as much as you example and rely on inherently probabilistic matters in any rebuttal, such rebuttals are irrelevant. Because we are not talking about our universe, or any universe in which there is inherent probability, but a deterministic universe. Which you accepted as a premise.
 
Not quite, but close...
Try,
A human being learns to co-determine his future actions within the determinstic universe. Therefore he becomes another determiner, the efficacy of which is determined by how well he learns to do so.
Example: There are over 7 billion determiners learning to determine better, on this planet alone. Other wise referred to as self determination.
The better he learns to co-determine the more genuine and numerous his choices become.
Freewill is not an all or nothing issue.
I pick this choice as my preferred universe. lol :)

Really, I think this makes the most sense.

This is puzzling...
You use the words "inherent probability"... in a strange way...
The universe doesn't have inherent probability.
 
Quantum interactions are inherently indeterministic
Not according to your definition of deterministic. (The probabilities, your source of confusion, determine them).
Nothing at the quantum level can do other than the equations say it must.
Specific outcome as in the one observed.
Which is determined by the interactions.
A probability function won’t be it, as that is just a description of the frequency of outcomes over an infinite number of replays.
That's not how probability works in quantum theory. That's how it is introduced, heuristically, in an introductory class in probability and statistics.
In a probabilistic process there is no cause,
In quantum theory the cause(s) is described by the mathematical equations, and determines the outcome - it's true that from our macroscopic perspective we have no adequate metaphor or analogy to bring to bear, so comprehension is both difficult and limited, but that is not relevant here.
You are only confusing the issue, and others, if you continue to push indeterministic processes (such as probabilistic ones) as being deterministic.
Certainly confusing you. Ok - I'll drop it. As I noted long ago, when warning it off, the muddles of quantum theory make no difference to the thread topic.

This does - we can restart here: " P1: deterministic interactions are not free" That's an assumption. It's not granted.

States aren’t illusion, and I have never said they are.
Bizarre. You're not joking.
Ok, square one: a driver approaches a traffic light. They have the capability of stopping, the capability of going, and the capability of choosing according to the color of the light when they reach it. That's the state of the driver, as they approach the light. None of that is "illusion", right?
What could be illusory is how they appear to us
They don't appear to me, the researchers who investigate them, the instruments that record them, and the entities that react to them, as anything other than observed states.
And all you have done so far is subsume conclusions into assumptions,
I quoted your assumptions, and pointed at them.
And that’s a different argument, starting from the nature of a deterministic interaction. It doesn’t start with the assumption that there is no freedom in a deterministic universe, as you accuse.
There is one argument under discussion here, just one, and it's not different from itself.
Meanwhile: Yes, it does. Right there in front of you. It's labeled "P1", by the poster. The P stands for "Premise", and a premise is an assumption.
James has gone into great detail on that topic, apparently thinking you are able to follow reasoning etc - me, I'm just going to repeat the plain fact of the matter whenever it seems appropriate to remind you.
or maybe taken subsequent arguments that build on the initial conclusion, seen it now stated as a premise,
It is a premise of that argument - that one argument, the only one at issue.
You mean the occasions when you’ve had to reformulate arguments to make your point
Never did that. You lost track of your own argument, and didn't recognize it, is all.
But instead, rather than actually seize on this to examine the question of complexity, and whether that gives rise to freedom, you once again try to use it, fallaciously, to claim an assumption of supernatural freedom.
Your language has gone slippery, as before when you went haywire - you seem to be trying again to have me claim that someone has assumed the existence of supernatural freedom.
What I claimed - and backed with multiple direct quotes - is that you guys are assuming only the supernatural can have freedom in a deterministic system - that to be free in such a system requires doing other than one (deterministically) must. You are thereby excluding, by assumption, all nonsupernatural freedom.

As far as "examining complexity" and whether that gives rise to "freedom", the many opportunities for that - all provided by me, alluded to by James - have been dismissed by you guys as "handwaving" and compared with thermostats and declared (without evidence or argument) to be nonexistent and trivial (both, by turns, even within one post).

But it isn't too late. The months I predicted months ago have passed - intellectual growth and insight are possible.
 
Not according to your definition of deterministic. (The probabilities, your source of confusion, determine them).
Yes, according to the definition of deterministic. If it is not completely determined it is not deterministic. And probabilistic outcomes are not completely determined.
Nothing at the quantum level can do other than the equations say it must.
Then they are not free, per the definition, but they are also not deterministic. You are confusing the definitions of free and deterministic, presumably in your obsession with the "supernatural assumption".
Which is determined by the interactions.
Not completely, hence not deterministic.
That's not how probability works in quantum theory. That's how it is introduced, heuristically, in an introductory class in probability and statistics.
That is the definition of probability, whether in quantum theory or anywhere else.
In quantum theory the cause(s) is described by the mathematical equations, and determines the outcome - it's true that from our macroscopic perspective we have no adequate metaphor or analogy to bring to bear, so comprehension is both difficult and limited, but that is not relevant here.
And the specific outcome is not fully determined by that cause. It could be any number of outcomes from within the probability function. Hence not deterministic.
Certainly confusing you. Ok - I'll drop it. As I noted long ago, when warning it off, the muddles of quantum theory make no difference to the thread topic.
:rolleyes: Why do you think the argument posted by baldeee et al start with the assumption of deterministic universe? So no, you didn't warn it off, and you don't get any moral high-ground from it. Rather pathetic attempt, to be honest.
This does - we can restart here: " P1: deterministic interactions are not free" That's an assumption. It's not granted.
So you continue to be dishonest, by not starting with the original argument but one that quite obviously starts with the conclusion of the previous. You can't help yourself, can you.
Bizarre. You're not joking.
No, I'm not.
Ok, square one: a driver approaches a traffic light. They have the capability of stopping, the capability of going, and the capability of choosing according to the color of the light when they reach it. That's the state of the driver, as they approach the light. None of that is "illusion", right?
That's not the state of the driver. They only have the capability of one of those things. The others are counterfactual assessments of what could be possible if the inputs to the system were different than what they actually are. But this has been explained to you, and I no longer have any intention of rehashing.
They don't appear to me, the researchers who investigate them, the instruments that record them, and the entities that react to them, as anything other than observed states.
Because they are not examining things from a philosophical point of view.
I quoted your assumptions, and pointed at them.
Already dealt with.
It is a premise of that argument - that one argument, the only one at issue.
That's an argument that was posted here, one subsequent to the conclusions already reached. But you know this.
Never did that. You lost track of your own argument, and didn't recognize it, is all.
Convince yourself of that if you must. The dishonesty of what you did is on record.
Your language has gone slippery, as before when you went haywire - you seem to be trying again to have me claim that someone has assumed the existence of supernatural freedom.
No slipperiness, and I never went haywire. And I don't seem to be trying anything of the sort. Your comprehension is letting you down. Yet again.
What I claimed - and backed with multiple direct quotes - is that you guys are assuming only the supernatural can have freedom in a deterministic system - that to be free in such a system requires doing other than one (deterministically) must. You are thereby excluding, by assumption, all nonsupernatural freedom.
I know what you claimed, and I know what you think you have supported it with, and each time your claim has been shown to be fallacious.
As far as "examining complexity" and whether that gives rise to "freedom", the many opportunities for that - all provided by me, alluded to by James - have been dismissed by you guys as "handwaving" and compared with thermostats and declared (without evidence or argument) to be nonexistent and trivial (both, by turns, even within one post).
You have offered nothing to support it. Nothing to support the nature of the freedom being any different than that found in a thermostat. Which to me, and others, is a trivial nature of freedom. You have suggested it. You have appealed to complexity. And... nope, that's it. In fact you've used every opportunity to simply not examine it further. Instead of heading down the route you want you spin round and return to where you don't want to be.
But it isn't too late. The months I predicted months ago have passed - intellectual growth and insight are possible.
And yet still here you are, trying to beat down a door with fallacious claims that we're assuming "supernatural freedom". You haven't grown, and you have offered no insight, just more of the same tiresome nonsense from you.

Offer something new and I may rejoin the conversation, but until then I have some paint to watch dry.
 
Yes it does. Read up on it.
sounds like it's akin to saying that the universe is inherantly mathematics.
You do realize that the mass/energy of the universe is not encoded with probability mathematics don't you?
But then again perhaps you don't...hence this nonsensical endless debate.
I am still waiting for you to support your non-caused events statement....

Perhaps you know of some uncaused events that Sarkus is rerrerring to?
Potentially everything since the quantum world ultimately rules everything. Quantum fluctuations, radioactive decay.

No one can "know" that something caused an uncaused event or it wouldn't be "unknown".

So we assume that the event is uncaused because we don't know the cause?

Actually I was reading up on spontaneous virtual particles emerging from the vacuum and how they appear to be un-caused. Appearances can be deceiving though. All the same I shall rest my case as I have found what I am looking for...and discussing causation for these virtual particles would go no where here.
 
So we assume that the event is uncaused because we don't know the cause?
Assuming a cause is a religious argument, then comes God as a first cause and then what caused God? If nothing caused God, the everything doesn't require a cause and you can take God out of the conversation.

This is similar to the watch in the forest argument. It's silly.
