Nope, that doesn't fly, by your own cited definition:...
The Schrodinger equation is one " in which no
randomness is involved in the development of future states of the system" (as it's a deterministic evolution of future states), and I've already stipulated that indeterministic results have no impact...like stars beyond the cosmological horizon.
It's a deterministic evolution of a wave function - an inherently probabilistic and thus indeterministic output.
From the same starting conditions you can end with different realised outputs - thus indeterministic.
Period.
No need to consider it further.
And that equation describes the process of how the state function evolves. Since the question is if free will is possible, like said stars, its impact has no bearing on its existence/possibility.
While we can see stars that have not slipped beyond the observable universe, i.e. we know their existence beyond our observation is a theoretical possibility, you have yet to show how freewill is even theoretically possible in the deterministic universe.
You have yet to even offer a notion of freewill, for that matter.
If you want to show how it is possible in a deterministic universe you need to do two things: 1. stipulate what you think freewill is (it is a key dispute in such threads) and 2. show how it might be possible to exist, or why it isn't possible.
Impact, meaningfulness, etc. are all questions beyond what you have stipulated.
As stated previously, I accept that there was a hidden implied assumption, that everyone other than you has accepted, that any notion of freewill under consideration would at least, if it exists, be meaningful, and have an impact, even theoretically.
You don't even seem to able to remain consistent on your stance on probabilities, since you want to allow them for the relationship between war/smoking and death but arbitrarily deny them for anything unfavorable to your foregone conclusion (begging the question).
The issue of probability is with regard the nature of the output for a given input.
War/smoking is not a specific input to a system, but a label for a range of inputs to that system.
So, to be clear: allowable probability - out of 100 different inputs, 40 cause death, 60 don't, thus the probability from an unknown input is 40% death.
Not allowable - taking 1 specific known input, there is a 40% chance of death, 60% chance of living.
The latter is contrary to a deterministic system.
But here's more reason that your own stipulations allow for the Schrodinger equation:...
If one can use the equation without probabilistic outcomes, and use it such that the same input will always output the same specific non-probabilistic output - no issue.
Nope, just playing by your rules. The Schrodinger equation describes a completely deterministic evolution. So it's only your question begging that arbitrarily denies things that YOUR OWN stipulation clearly allow.
Not at all.
If the evolution is of an inherently indeterministic output (e.g. wave function), it is irrelevant whether the equation is deterministic or not, as the relationship between input and output of specific states of the system is not deterministic.
And if "probability has no place", then you must agree that war and smoking never cause death. That's the silliness your stipulations lead to, and you must accept them all or none at all. Otherwise you are arbitrarily begging the question.
Probability has a place if it is of the former example I gave above.
Not the latter.
Do you at least recognise that there is a difference?
But if you take the right limit, you can use the Schrodinger equation to construct classical orbits.
As shown above, the Schrodinger equation can be applied to classical physics. THAT should really be the end of the matter.
It is not the equation that is the issue, as I tried to explain previously, and again above, but the subject of the equation: if it is inherently probabilistic such as a QM wavefunction then it simply doesn't matter that the equation is deterministic.
Try answering the question asked. Existence/possibility does not determine whether a thing has an impact, such as stars beyond the cosmological horizon. The question here, according to you, is whether free will is possible, NOT whether it has an impact. Stick to your own stipulations already.
I haven't said that existence or possibility do determine such things.
I have accepted that there was a hidden implied assumption that any freewill being considered would, if it existed, be meaningful and have an impact.
Apologies if this has confused you.
A deterministic universe allows ANY deterministic system, not just the ones that make your conclusion foregone.
My conclusion is simply based on what it means for a system to be deterministic.
And that does not include any whose outputs are probabilistic.
Quit asking questions you've demanded we cannot talk about in this thread, including what free will is, which necessitates how it operates.
Where have I said that you can't talk about what free will is???
How can one answer the question without doing so?
Again, the question is "is free will possible", not is it meaningful or can it have an impact. Quit making arguments you've already demanded are irrelevant to this thread.
I haven't said that they are irrelevant to this thread.
If anything I am saying that your analogy suggest you are making freewill irrelevant to everything else.
I'm not suggesting free will has no impact on your stipulated universe, only that "impact" is clearly beyond the scope of this thread.
That freewill is something that has an impact is a hidden and implied assumption, one that everyone else has accepted.
Are you ever going to even answer the question the thread asks?
If you were smart, you'd be intellectually honest, consistent, and agree that:
your completely deterministic universe allows ANY deterministic system or process, so long as no indeterministic outputs can be therein observed
I admit to ignorance of the schrodinger equation being used for deterministic outputs, and even reading the article I'm not convinced even then it is but rather still offering a probabilistic model to a classical issue.
But it is not just a matter of whether they can be observed, but whether they exist, or are possible.
As I'm sure you would agree if you were being intellectually honest and consistent.
A deterministic system is one where indeterministic outputs are not possible, not just where they are not observed.
probable causes either exist or they don't, period, even if that means that war/smoking can never cause death
Anything and everything either exists or it doesn't, period.
"impact" has no bearing on existence
I have never said otherwise.
I've already explained to you that war and smoking can only ever appear to cause death in such a universe. Neither can actually cause death therein. So the only appearance is the seeming determinism, where the actuality is probable. Otherwise, smoking would ALWAYS cause death and war would ALWAYS cause death. IWO, one puff...dead. One war, everyone on both sides...dead. That's how deterministic systems work. If A caused B, A always causes B, no exceptions.
...
Nope, you clearly don't understand that basics of what you've been demanding to stipulate. Again, in a deterministic system, if A causes B, A ALWAYS causes B.
Let me clarify:
War/smoking is not a
single input but a vast set of possible inputs, any one of which we might refer to as "smoking" or "war".
Not all such inputs will result in death but some will, and so it is quite correct to say that smoking/war
can cause death.
This is quite consistent with a deterministic system.
It is the same way that if you have a deterministic system that always adds one to the input integer, then there is a 50/50 chance of an odd number being output when all possible inputs are considered, but there is no such probability when a single input is considered.
E.g. if I input 2 then the output will be 3, and there is no probability of anything else.
But just because you can say that "smoking has a probability of death" also does not mean that it is not a deterministic system - because "smoking" in this context is not a single input by which the determinism can be judged.
In the deterministic system as complex as one that allows for labels such as "smoking" and "death", no two inputs will ever be the same.
We can only ever group inputs into sets that have similar properties judged (usually) at the macro level.
But when we do get inputs that are the same, we will always get the same result.
In a deterministic universe, the determinism isn't the appearance, it is the actuality.
The probability that macro-cause X will result in macro-result Y is the appearance, and it
appears that the same cause ("smoking") can end in different results - and thus appear to be indeterministic if treated as a system in and of itself.
But the macro-cause X of "smoking" will never actually be identical from example to example, and the deterministic system requires identical inputs to be able to be observed as deterministic.
As such, the observation, the appearance, isn't the deterministic nature of such a complex system.
Again, "impact" is clearly beyond the scope of this thread. So quit arguing irrelevancies.
Other than the hidden assumption mentioned before, consider it me being curious as to what you think free will actually is, so that I might be able to eventually agree or disagree with you when you deign to actually give an answer to the thread question.
