Dynamic Gravity theory to explain dark matter, cosmic ray energy, etc.
Nope. I have no idea of why he referred to Aristotle. Given that he talks about vacuum, I suppose he refers to Aristotle's ideas about it: namely, that a real vacuum does not exist. According to A, objects move with a velocity, proportional to the 'impetus' divided by the density of the medium it moves through. As the density of the vacuum is zero, the velocity would go to infinity. That was absurd according to A, so the vacuum does not exist. But I think physics has made a little progress since A's days...

What are the benefits of understanding our free will?
Why this denigration of philosophy, even after I repeatedly corrected you? You cited Plato (the ancient Greek philosopher...), you cited Einstein, giving the impression that he thought philosophy is useless, which is not the case, etc. I discovered no change in your position, or arguments against mine. Therefore my 'snipiness'. Well, that is really confusing, calling SEP 'Plato'. So I am sorry if I misunderstood you, but only if I really misunderstood you.

He said a lot about a lot of things so not until you tell us more specifically, no. It is of vital importance to know what Aristotle said, if you want to understand modern physics... No?

What are the benefits of understanding our free will?
I think they are. No. You believe they are. For the record, not from me. But somebody else already compensated you . +1 is too much, for somebody who doesn't want to engage in a philosophical discussion about a philosophical topic in the philosophy forum. I think making the same step again and again is the better metaphor. In my opinion, the problem is that people stick to some out-of-date ideological meaning of 'free will', that is not rooted in our daily use of the concept of free will. Of course, I fully accept your experience of free will. But obviously, instead of trying to reflect on this experience, people take, unreflected, some metaphysical, or theological meaning of the idea of free will. In your case, it leads to a (partial) denial of determinism (you say the future is essentially open, don't you?). In @iNow's case it leads to a complete denial of free will. The idea you have in common is that determinism and free will are contradictory, so one of them has to go.

Current state of the debate between free will and determinism in philosophy and neuroscience
A concept of "freedom" that does not apply: in your conception of "freedom" nothing is free, and so it is a useless category. So when somebody praises your wood works (I do), you react "Nothing to praise, I blindly followed the commands of my body. And if my body commands me to kill you, I would do it, I could not do otherwise, I have no say in what I do. Do not blame me, it was my body". Don't you see that such a concept of free will is useless? That it has nothing to do with the daily use of the idea of free will? I did not realise that earth's climate has intentions and knowledge, and acts according them. I do not understand why you would like to stick to an old-fashioned and useless metaphysical conception, deny its existence (this is at least the part I can agree with), and then think you have denied every (including more useful!) other possible conceptions of what we mean when we say that we did something of our own free will.

Is the Aristotle method of the four elements any use in sending space probes to Mars? @studiot: why are you still asking such stupid questions? Did you pick up anything I wrote about philosophy in this (and other) threads?
-
What are the benefits of understanding our free will?
False dichotomy. When you know that there are many philosophers who are compatibilists, then you should know that determinism and freedom of the will are not a priori contradictory. But one should not take a useless definition, that in the questions in which free will or not play an important role, does not help at all: things like blaming, praising, guilt, punishment etc. Sticking to an old-fashioned definition, based on metaphysical assumptions, coming forth from a Christian background, and is not coherent, just makes no sense.

what is current in capacitor
Ohm's law for a capacitor??? Are you really designing microprocessors? Not my topic, but capacitors build up voltage until it is the same as the voltage in the circuit. Then it behaves just like a insulator, so the current stops (unless you overload it...) As the capacities you mention, the 4.7 μF is slightly bigger, so it would take a tiny bit longer before the current ceases.

Current state of the debate between free will and determinism in philosophy and neuroscience
I found your reaction in this thread: I agree, but I am wondering why you do not apply the same way of thinking in how you see free will. If I would use the same argumentation scheme as you do with free will, you should have said "Neurons cannot do analysis. the brain is made of neurons. Conclusion we cannot do analysis". 'Free will' only makes sense when they form mental phenomena like intentions, believes, decisions, and actions. As we are able to do analysis, we have these mental phenomena, arising from the complex connections between neurons. Defining 'free will' in terms of these mental phenomena makes sense. Defining in terms of neurons doesn't.

The Observer Effect
Is a wave function a physical object, that can collapse? I like your description, except this 'split photon'. Photons can't be split. And just imagine how the two half photons find together after the split, carefully avoiding the 'dark zones' on the detection screen...

Artificial Consciousness Is Impossible
No philosophy here. Neither science. Just a list of crackpot ideas, completely detached from reality and the discussion in this thread.
-
What are the benefits of understanding our free will?
Can be: I am not a native English speaker. But in philosophical discussions, 'coercion' is the most used word. Do not use rhetorical questions in philosophical discussions, except when it is perfectly clear that it was meant as such. Some are definitely better than others. Reread my definition: Often we cannot. And as my intentions can be inconsistent (see my reaction to Giordief), and I may not be sure about what I really believe in, so no, it often will not be the case that I can act in such a way that all of my intention and believes are fulfilled. But once I made decision, then it can becomes quite clear: can I act according my decision, or does somebody intentionally block my action?
-
What are the benefits of understanding our free will?
No. It has no will. It's behaviour is not formed by personal taste, intention, values, etc etc. Why do you start from the beginning? I use a clear definition of free will: We are said to have free will if we can act according our intentions and believes. You may shoot holes in this definition, but I find it useless to start the whole discussion from the beginning. Coercion. The question if somebody acted out of free will or was coerced is a meaningful question. The same question about a falling stone is useless. A stone has no will, because it has no intentions and believes.
-
What are the benefits of understanding our free will?
Well, if you think only libertarian free will is the correct concept of free will, and we do not have it, sure. But the concept of libertarian free will is incoherent from the outset. Well, if everything is determined, then of course '(actions) are woven in the web of causality'. I never denied that, and even stated it: determinism is a necessary condition for free will to exist. As I said just above what you cited: Sure we can. What our motivations (values, intentions) are, are part of my identity. That question is not quite clear to me. Can you give (counter-) examples?
-
What are the benefits of understanding our free will?
That would definitely lead to a Gödel-like situation. If I know this listing in advance, I can adapt my behaviour so that I will not do some of the actions on the list. The only way to avoid that, seems to be to account for me knowing the list. But that would change the list, and therefore my actions, and therefore the list... An easier way would be to keep the list secret, and read it the day after. Then I could be astonished about how well Laplace's Demon did his work. But it would have no impact on my actions. And neither on my evaluation of how well my actions were in accordance with my knowledge and intentions. No. It applies to everyone who is able to predict my actions, as long as I am not manipulated by somebody else. Where I do agree that a logical deduction was involved, to do so, and act according to my logical conclusion makes my action free, it is not the logic itself that makes me free. How many people have come to the conclusion that they should stop smoking, on perfectly logical grounds, but do not succeed? That is a good question. And it would take some precise definitions to answer the question. But my short answer is: yes, we are one person, but we have conflicting motivations, and maybe also doubt about facts. That means a person is not a rigorous unity. Oh yes! But nobody promised you a rose garden, is it? And that is exactly why I made my remark. When you pose something, shortly after I posted an opposing view, it would be interesting to know what your arguments against my position are. Exchange of arguments is one of the corner stones of philosophy, and this is the philosophy forum. And also SFN is a discussion platform. It would be a pity when threads are just independent opinions without arguments. Having an opinion is easy, especially in philosophy. To have a well argued opinion is definitively more work.

What are the benefits of understanding our free will?
No, you cannot just say that your taste, as something you acquired because of your biology and upraising, is determined, but your will to be on a diet is not. This would still be libertarian free will. In my view everything is determined, so for me it makes no sense. In compatibilist free will, all we do is determined: but possibly in different ways. There lies the crux: the question of free will is not if we are determined (we are), but along which causal pathways our will was determined. However, you touch an interesting point: is it possible to be more or less free? I think the question is how you formed your will, what you decided, and how well you can keep to your decision. Do you identify with you being on a diet, or does somebody threaten you (e.g. you spouse wanting you to lose weight, threatening to divorce from you if don't do it)?

OK, it seems you are determined (intentional ambiguity) not to soften your tone.
-
What are the benefits of understanding our free will?
Your argument is valid only against the concept of libertarian free will, not against the concept of compatibilist free will. It would be nice if in the philosophy forum, arguments are exchanged, not just viewpoints. I gave an argument against the idea that unpredictability is an element of free will. So now I expect an argument for your viewpoint from you. Or an argument why mine is wrong: So why don't you share your thoughts? What are the experiences that convince you we have free will? And what kind of free will? As said above, having an opinion about a philosophical topic is not philosophy. Having well-reasoned arguments, and present them, so others can understand your trains of thought, and evaluate them, that is what makes exchanges of ideas philosophy.

Current state of the debate between free will and determinism in philosophy and neuroscience
Or for a more objective approach: Peter Millican on free will and responsibility: 7.1. There are three more, alltogether about as long as iNow's podcast. @studiot: may also something for you? Might give a better impression about the progress made in philosophy then giving Plato as an example of modern philosophy... It doesn't need a megaphone to see different concepts of free will, and then choose for the best definition that fits the use daily life best...

What are the benefits of understanding our free will?
Yes, and a mass that is twice another mass falls twice as fast. Aristotle said so, and he was (also) a physicist! No. It is just as irrelevant. Should be clear. Referring, and citing some ancient philosopher, even when it is Plato, has nothing to do with what present day academic philosophy is doing. Your citation comes from Plato's Timaeus, and it is a difficult to understand explanation about proportionality. Why should you give a text of more than 2000 years old, as an example why philosophy is BS, useless or ununderstandable? So I gave an example from physics, showing that it is BS. But doing this with a view of a physicist from 2000 years ago is just as irrelevant as your citation of Timaeus. And why citing Einstein, when at other places he suggests that physicists should also study philosophy, as he himself did, e.g. Spinoza, Ernst Mach or Kant. From wikipedia. I'm sorry, I don't know Kane's ideas, but I know Dennett refers to him a few times. I am inclined to think that entropy and non-linearity are not that relevant. Of course it makes predicting what somebody would do extremely difficult, and there are people who think unpredictability is an essential element of free will. The 'evolutionary' advantage would be that e.g. a predator cannot know in advance what his prey will do, and therefore not able to catch it. But I think predictability has nothing to do with free will. I do not feel that my free will is constrained because my wife knows me pretty well, and can predict (better than others, at least) what I will do. So why would I be disturbed by a neurologist predicting my decisions, choices and/or actions even better, as long as I am able to act according my intentions? Somebody who believes in libertarian free will would definitively be disturbed by it, compatibilists not so much. As you probably know, Dennett has a kind of Darwinian view on what happens in the brain. Several strands of thoughts or feelings develop in parallel, and one of them in the end 'wins', meaning it catches access to motoric neurons, and leads to an action, be it a real bodily movement, or something spoken out. (Therefore he names his model the 'multiple draughts' model of the mind.) Ah, well, I am not in favour of the concept of 'ultimate personal responsibility'. For me that is a chimera piggybacking on libertarian free will (one could describe it as 'absolute' free will, the conceptual companion of 'ultimate personal responsibility'). In compatibilism 'personal responsibility', without the 'ultimate' is more than enough.

Current state of the debate between free will and determinism in philosophy and neuroscience
Hmmm. That would mean that neurologists would encounter what I called a 'causal hole'? Or would they not be able to map brain states with mental phenomena? Or would they not be able to explain how 'C-fiber translating data packets through superior medial cortical stacks 9 and 43' cause a certain intention? If you mean the latter I agree: the relationship is not causal, but one of supervenience. Just as a book (i.e. a pile of pages with ink blobs on it) does not cause a story.
-
What are the benefits of understanding our free will?
To add to this: Spinoza said that, if a stone falling to the ground would be conscious, it would think it acted freely. Schopenhauer later added that the stone would be right. In the end, 'free will' is not to be able to want what you want, but to be able to do what you want. Sounds familiar?
-
What are the benefits of understanding our free will?
No. It is just as irrelevant. I would suggest you read my exposé again. If you still wonder what philosophy is, then just ask. The short reaction is: philosophy does not have the same subject as the sciences, so it definitely is not an alternative method to reach empirical truths. Then please point to passage where you agree with. I know who Rudolf Steiner was, and I agree with your second bullet point. Just as an aside: Steiner is not taught in academia philosophae... Justified. You mean: if no usable definition of free will can be found... Well, yes, philosophers still discuss this again and again. I my my eyes, because there are still too many people (and there are even such kind of philosophers) who still stick to the logically absurd idea of libertarian free will. Where I think we cannot exactly quantify free will ("Sir, he has only a free will of 37 Scoville!"), in our daily life we definitively can recognise how some people are freeer than others. And it is an essential factor in assessing how guilty somebody is in a criminal case. So this is the place to look for, at least trying to, investigate if we can design some scale of 'coerced - completely voluntary' where we can all more or less agree with. Neurology and even worse physics, have nothing to say about free will in daily life. A speculation of mine is that neurology might once be able to: but not because they discover some indetermined process in the brain, but because they are able to map the different states of the brain of people who make free decisions on one side, and people who are coerced to do an action. That is nearly correct. Spinoza defines 'free' as (definition 7): But 'God' as ±'nature', is the only thing not constrained by 'something external to itself', God is the only one from who (what) can be said that it is free.

Current state of the debate between free will and determinism in philosophy and neuroscience
I hope you also read the rest of my posting...: And, yes, I have put quotes around 'elsewhere'. I wanted to express that from the view of the physicist or neurologist there is no reason to suspect that there is still a causal component missing, i.e. they do not have the full picture: in their view the system is 'physically causally closed'. I do not have time now to fully explain my ideas, but even then, these do not lead me to a definite position if 'downward causation' is the correct concept to describe what happens. So here is just one thought: a system can express free will only when a higher level description in terms of intentionality and actions is valid. To give a negative example (much used in the metaphorical sense, but still leads to confusion sometimes): Objects want to move with constant speed in a straight line, but planets are forced to move in ellipses around the sun by its gravity. Assigning free/forced speech just makes no sense here. But for humans it does. BTW, same holds for 'laws of nature': they do not force objects to behave like they do; they are descriptions of regularities we discover in nature. I might have a problem in this 'irreducible value'. Can you explain? - - - @AIkonoklazt: To be honest, I have no lust discussing with you. For me, you speak too often in a denigrating tone to, and about others. Maybe you should reflect a bit more on yourself, when you have the experience that people react hostile at you, and are even thrown out from other fora, as you wrote yourself: I love exchange of arguments, but not when the question is "who is right". Seeing what the better arguments are, that is interesting. I only have a simple question, but I will only ask it, if you are prepared to down your voice a bit. Maybe you have deeper insight in this stuff then I do. But nobody wants to be treated as if he or she is dumb, or an asshole, or both.

Current state of the debate between free will and determinism in philosophy and neuroscience
Nah, it slowly gets time to think about the 'downward causation', you mentioned it already several times, and (nearly?) nobody reacted on that. My first assumption is that the universe is physically causally closed. That means that no momentum or energy somehow just leaks away, or arises from nowhere. E.g. the neutrino was proposed as a solution for missing energy in beta-decay. Only after 30 years (or so) it was confirmed that the neutrino really existed. My next assumption is that the brain is also physical, so we will never find physically causal holes in brain processes. That means that we will never find that a soul interacts with the brain: not as input (which would have been a nice gateway for proposing that we have libertarian free will), nor as output (which would have been a nice gateway for epiphenomalism). (And both together for interactionism.) Neither the neurologist, nor the physicist, studying the brain on their respective levels, will ever have to refer to some none-physical causes. So a 'cause' coming from 'elsewhere', (and wouldn't a downward causation be such a cause from 'elsewhere?) does not fit in this picture. So case closed. But to speak with PBS Spacetime's Matt O'Dowd: "not so fast". Take the following computer program: wait 10 minutes; shutdown computer; Such a kind of program can be written for every kind of computer system I know: Linux, Windows; and I am pretty sure Mac too, in short, all kinds of computer systems. Now imagine we give a computer running such a program to a physicist, and ask him to explain why this Linux computer stops after 10 minutes, but we allow him only to explain it on physical level. Theoretically, he can succeed (maybe 10 minutes is a bit short...). Using the physical architecture of the computer, and the laws of quantum mechanics he can causally explain why the computer shuts down. That means also, that his explanation is 'physically causally closed'. But now we give him another computer, running with Windows, and ask him again to explain why the computer turns off after 10 minutes. Now he must start all over again, because the hardware is different, and so are the changes because of the different operating systems. Assume he will just as well succeed. But let a programmer look, and she can tell in one glance why the computer stops. Would that count as 'downward causation'? Personally, I am inclined to say 'yes', because at least I have a better feeling of understanding why the computer stops by the programmer's explanation. Let's take a more complicated example: we organise a virtual tournament between two chess computer programs, A and B. A and B both have a red light, which signifies who has won the match. In about 70% of the cases, the light at A burns after a match. So we see the red light mostly flashing up on the A-side, but sometimes on the B-side. We ask the physicist for an explanation why sometimes the light at the A-side burns, and sometimes at the B-side, same conditions as above. Well, assume again he is able to understand what is happening, in a similar way as the simple program above. But did we learn something from his explanation? And do we now have a full understanding why in 70% of the cases the light at A-side flashes up? In the first place, we would understand much more if we knew, at a higher level, the lights depend on games of chess, and signify which program won the match. But in the second place, how correct the explanations of the physicist might be, can we say that he really understands why in 70% of the A wins? Let's ask the system administrator: "no, they are the same programs, both X-Chess". Are you sure? So she looks better, and suddenly she says "Wait! B is version 1.0, A is version 1.1. One moment, I'll look up the release notes". And there it is: Now we understand why the light on the A-side turns on more often! B just can't do certain moves, because they are not implemented in it. What would you say, @TheVat? Is this also an example of downward causation? At least, we need the knowledge that the hardware has implemented two chess programs, and by understanding chess, we understand what physically is happening: A's light burns, or B's. I'll make the arc to my compatibilist understanding of free will. Only on the level of persons mental phenomena, intentions, believes, observations, aesthetical and ethical values, and actions exist. So only on that level, free will can be meaningfully defined: as acting according my intentions, believes, observations, aesthetical and ethical values. Nevertheless, all the mental phenomena 'run on the physical wetware of the brain'. And therefore the physicist and the neurologist will simply not be able to find these on their respective level of explanation. Imprisoned on one side by their detailed view on reality, and mostly by using a meaningless, useless and theological concept of free will, they do not see the wood for the trees.
