I never disputed that. There is no such "dispute" of mine. I have stipulated to predetermination from the beginning - finding your insistence on extra typing bemusing, but no issue for anything I post. As you were warned, it seems to confuse you, but you insist, so - - - -
Um. Okay. So none of this rings a bell....?
Post #520: Iceaura: “
Determinism does not establish predictability, even in theory, because full knowledge does not always enable calculation, even in theory.”
Post #531: me: “Yes it does. If the state is known, and the laws that govern how one state translates into the next are known, then one can predict the next state.”
Post #534: iceaura: “
Not necessarily. You have to be able to do the calculations - and that is not always possible.”
Post #541: me: “In a fully deterministic universe it is.Only when you intorduce indeterminism (e.g. probabilistic events) does it start to become impossible.”
Post #568: iceaura: “
No, it isn't. You are now arguing with mathematical proof.”
Post #587: me: “You'll excuse me if I don't take you word for that. What proof shows that in a deterministic universe it is not possible to "do the calculations"? Remember, I am not referring to simple practical capability, but what is inherent within the universe. Stump up this proof, please.”
Post #588: iceaura: “
You have claimed that with perfect knowledge of the present the future state of any deterministic physical system can be - in theory - exactly predicted, without running the entire system and recording the outcome. That involves doing the calculations and arriving at exact numbers - exact solutions of the equations employed. Your claim requires, in part, that such exact solutions be always possible, in theory. That is what you want to check.”
Post #600: me: “There is nothing to check here, as it is the logical conclusion of causal determination. The universe is a perfect calculator of the system. It has perfect knowledge of the system. The rest is simply a logical implication of what it means to be causally deterministic.”
Post #651: iceaura: “
It isn't.
That's the problem. That's why I quoted your argument, and pointed to the invalid step.
You can't conclude an absence of freedom from causal determinism alone.Itdoes not follow.”
And in the same post in response to the last line of mine above: “
That is false.
You can't get from causal determination alone to absence of nonsupernatural freedom by logical implication.”
And you think that I am the one confused? You have jumped from your inability/unwilling to provide support that it goes against mathematical proof to conclude that theoretical predictability logically follows from causal determinism, to thinking my responses were to do with the absence of what you term “nonsupernatural freedom”. I have never claimed an absence of “no supernatural freedom”, otherwise I wouldn’t be referring to it as “trivial”, would I, but rather “non-existent”.
I have said that your claim of exact prediction necessarily following from perfect knowledge of a deterministic system goes against mathematical proof.
A proof you have yet to provide. And given that the universe has perfect knowledge, its predictability is otherwise known as predetermination. You don’t dispute the latter yet you bemusingly dispute the former. But I’m sure the proof you’ll inevitably fail to provide will clear everything up, right?
I advised you to check that claim - knowing what you will find, if you ever do.
If you make the claim, as you have done, that it goes against mathematical proof, the onus is on you to support it. It is not for me to do your legwork for you. You are simply making rebuttals on the strength of your confidence, and while that may work for some, you’re going to have to do better here. My claim (that predictability is theoretically possible) has been argued and supported with the logic of it. Your rebuttal? Well, we have your confidence... and...?
I also pointed out that the entire matter was irrelevant here, except as an illustration of the damage the supernatural assumption can do.
Assuming you are referring to the conclusion, and not the assumption, you have illustrated nothing but damage to agreement with you. What other damage do you think it can do? Please provide examples, as I’m curious.
And as for relevance, not irrelevant at all, as it still speaks to resolving the nature of freedom that QQ is referring to within his theory.
btw: Since that is the only thing here I have ever claimed goes against mathematical proof -
Where do you suppose you got your errant post from?
From you. And it’s not errant, as the above demonstrates.
Not by anyone interested in making sense.
Deflecting from your inability to grasp the meaning does you no favours.
You have it backwards:
As with almost all naive materialists, your underestimation of the physical universe has a direct, obvious, and critical bearing on your assessment of nonsupernatural freedoms in that physical universe. It prevents you from considering them carefully - or at all, even.
Utter codswallop. You really are full of it, seriously. If it helps to put yourself upon a pedestal, by all means find the highest one you can find, it won’t stop you spewing the drivel you do. I’m sure you’ll claim it stops me from considering studying the French language, or Geography as well? Sheesh. First unsupported claims and now just utter inane nonsense.
That is the case with almost all naive materialists in discussions of this topic. Bricks, thermostats, sleeping vs dead dogs, human decisions, a pile of sand - all the same "nature" of freedom, all dismissed with the same wave of the hand and some label like "trivial".
When you want to stump up something other than an appeal to complexity, or simple quantitative differences, by all means feel free to discuss it with those that want to. At the moment you’re just acting like a baby crying because you can’t get your way, you want the attention of your parent but they’re not giving you the attention. You have spent about three whole threads focussed on someone who from the outset has stated no interest in what you want to discuss... and yet here you remain, like a limpet. And I’m the one to blame, apparently, right?
And then: Somebody posts a simple example to clarify and focus - driver approaching a light, say - and they can't even register the key circumstances when paraphrasing. It's all sand. They screw up the timeline, change the subject, lose track of what is input and what is output, make a damn mess.
If you can’t grasp what they’re saying, and you really haven’t been able to, that much is clear, then ask them to clarify. Others have been able to follow, and understand. But no, you simply repeat ad infinitum that your example evidences your point, when it doesn’t.
But hey, that’s the issue with naive compatibilists, I guess.
And these are not reductio ad absurdum arguments, not ludicrous meanderings designed to mock some especially incoherent "incompatibilist" approach - they mean them, sincerely.
Oh, I have no doubt they mean them, but it doesn’t change what they are. You can’t make an argument interesting through force of sincerity, you can’t make it any more correct through confidence, through unsupported claims.
Look, do us both a favour: don’t respond to me, okay. I’m putting you on ignore, ‘cos frankly, no matter how high your self-constructed pedestal may be, it won’t alter your dishonesty, nor make me want to discuss the trivial notion of freedom that you clearly want to, even if you have nothing but appeals to complexity to support it.
