Of course given physics and materialism, sans metaphysics, free will is s myth. But the calculations are so difficult you may as well believe.

I think we have free agency within various external constraints. Which means we can try to find ways to circumvent external constraints, while also understanding that, as the fictional Ian Malcolm Smith put it, just because we can do a thing doesn't mean we should do it.
It is an impossible concept invented by humans. Free from what? Literally everything you do is because of things beyond your control. It isn't predestined, it just isn't up to you. The question is, at the end of the day, were you kind?
What explanation do people envision, after which they would both understand the mechanism of free will and are convinced it exists? That understanding just seems contradictory to me, so either it doesn't exist or we can't define it.
No I don't.
To add to this, I've noticed not only here but anywhere I ask this question there is a camp of people who immediately become defensive and say the question is pointless. In person it can lead to people getting very angry sometimes at the idea and that is odd to me. I don't really see how the question is pointless, and instead it seems to me like some people feel intimidated by it
Yes.
I observe free will directly. Watch: I will choose of my own free will to type a tilde at the end of this sentence instead of a period~ Behold free will.
Everything that says we don't have free will depends on indirect observations that blatantly make faulty assumptions. Do our senses accurately tell us about the state of the universe, and ourselves within it? Are our interpretations of this infallible?
Most egregious is the assumption that classical mechanics governs the mind, when we know that at a deep level, classical mechanics governs nothing. Quantum mechanics is the best guess we have at the moment about how objects work at a fundamental level. Many will say neurons are too big for the quantum level. But everything is at the quantum level. We just don't typically observe the effects because most things are too big to see quantum effects from the outside. But we don't only look at the brain from the outside.
Nor can we say that the brain is the seat of consciousness. Who can say what the nature of reality is? Does space even exist at a fundamental level? What does it mean for consciousness to be in a particular place? What's to say it can only affect and be affected by certain things in certain locations? Especially when we can't pinpoint what those things are?
So yeah I believe in free will. It's direct observation vs. blatantly faulty reasoning.
If there is an unbroken chain of causality, that means that history has been written start to finish already, and my consciousness is just along for the ride. The thing is, my consciousness is locked to right now, which is a single point in this 4-D space, as are all the consciousnesses that I interact with because thatβs exactly what right now is.
Until the day I interact with a consciousness that is experiencing a different point in 4-D space other than right now, it does not matter if free will truly exists because from my perspective and from all of my scientific testing so far (like deciding to pick my nose as I just did), evidence suggests that my consciousness is capable of making decisions. Even if those decisions are all a result of a deterministic path, my consciousness felt like it made them so it might as well have.
Yes but I need to define free will, I define it as the freedom to make a choice. We don't control who our parents are, we don't control what country we live in, we don't control how others interact with us but we can control what choices we make.
We can chose option A-B-C.....
I believe that we should treat most people as if they have free will but I don't exactly believe in the idealistic notion of free will. I believe we can make choices, but I believe our choices are limited and shaped by our experiences.
You have free will, but you also have chains that bound you.
Starting from the social order, you need money and other social relations (friends, family, bosses) to literally survive in the modern world - you're not omnipotent.
Then you have the cognitive chains - stuff you know and understand, as well stuff you can invent (or reinvent) from your current knowledge - you are not omnipresent.
Then, as a consequence, without these two, you cannot be (omni)benevolent - you'll always fuck something up (and even if you didn't, most actions positive towards something will have a negative impact towards something else).
All these are pretty much categorically impossible to exist - you're not some god-damn deity.
But does this mean free will doesn't exist?
Hardly. It's just not as ultimate a power or virtue as some may put it. Flies or pigs also have free will - they're free to roll in mud or lick a turd - except for when they're not because they do it to survive (cool themselves or eat respectively).
We humans similarily eat and shit, and we go to work so we have something to eat and someplace to shit. Otherwise you die without the former or get fined without the latter.
So that's what free will is - the ability of an organism to guide what it's doing, how, when (and, to some extent, even why) it's doing it, according to its senses and sensibilities. It's the process with which we put our own, unique spin on the things in our lives.
Being an omnipotent, omnipresent and (omni)benevolent would in fact remove the essence of what free will (with all its limits) is, because our actions wouldn't have any meaningful consequences. It'd all just be an effective (what I'll call negative) chaos - a mishmush of everything only understandable to the diety.
So in fact, the essence of "free" will is that it's free within some bounds - some we've set ourselves, some we're forced with (disabilities, cognitive abilities, physical limits, etc.). Percisely in the alternative scenario would "free" will cease to be free - because someone already knows it all - past, present future, local and global, from each atom on up. There's perfect causality - as perfect as a movie. You can't change it meaningfully - any changes become a remix or remaster - they lose their originality.
With the limits on our thinking which cause us to be less-than-perfect, they cause a kind of positive chaos, one where one tries to do their best with what they have on their disposal - as they say, you get to know people best at their lowest. Similarily, everyone gets corrupted at a high enough power level - some just do it sooner than others. So surely, at an infinite power level, not even someone omnipotent, omnipresent and (omni)benevolent all at once would be able to curb this flaw.
honestly, i've never seen or heard a single coherent definition of what we even mean by 'free will'. until the question makes sense, i can't really answer it, and don't see any point in discussing it.
anyways, who here believes in blabblesnork? that is a word that refers to something, i promise, but no, i won't tell you what it means.
Every decision you make and everything that happens is based on conditions, and nothing exists outside of conditions.
In the ultimate sense there's no such thing as free will, because everything has a conditioned existence.
Get in the car and go until the scenery looks different. Be somewhere you don't belong and you'll feel more in charge of your choices and decisions. Every single person has the ability to be a wild card and go off script if they choose it. That's free will. Embrace the wild.
If it looks like free will and quacks like free will, then it probably is free will.
There is only one choice: feeling or rationality.
When you feel, you do what feels best.
When you think, you do what is the most valuable.
So no free will but that choice.
The circumstances that led you to any particular decision are pre-determined at the time you're making that decision, simply through the fact that those circumstances have already happened prior to the current decision at hand; but that doesn't mean you don't have the free will to make that decision in the moment.
To extend on that a little: if you were able to make the same person face the same decision multiple times under identical circumstances, I don't believe you'd get identical results every time. It may not be an even distribution between the possible choices; but it wouldn't be a consistent answer either. The Human element introduces too much chaos for that kind of uniformity.
No. We make choices, we think, but those choices come frome somewhere. And all of the roots are beyond our control. There is no room for free will, it is a magical reduction of why we do things. We don't say a ball has free will when it is kicked down a hill. I can't separate myself from the ball in any meaningful way.
it all depends on how you define a person. Most likely, you think that a person's consciousness is something inside the brain, and in this case, the "external" body really influences your decisions. But that's not how it really works. The body is also a part of you, so everything that happens inside it, including "the hormone levels", is a part of you. And your experience is a part of you too. It's just that you can't control it, but that doesn't mean it's not your decisions. Otherwise, we will come to the conclusion that muscle memory is also not a part of you, but some kind of external factor. In general, if you are interested in my answer: yes, we always make decisions on our own.
Muscle memory is stored in the brain, if you didn't know that already.
Fun thought exercise but functionally irrelevant. It still feels like I'm making decisions, so that's close enough.
Yes I do, because my own experience of existence suggests I have it. Could that all be an illusion? Sure. But believing I don't have free will would pretty much deny the existence of my self, which, being myself, I'm not really capable of, nor would I want to do that.
You could define self differently. Buddhism has some fun takes on it.
I think there may be a paradox hiding in your question. You cannot believe in free will. You have it or you don't - I would postulate you need a neutral third-party observer to tell you. For us humans, a Martian might do. Believing is an act of faith. Faith tends to bend will to its dogmas. I would go so far as to say belief is the natural enemy of a free will.
We are distracted animals. All things being equal, the Martian observer will after years of careful study come to the conclusion that humans have free will. But it's constantly battered by short attention spans, a tendency to go with the herd, presupposituons in our heads that we don't often or never question, etc. We are a smartphone full of bloatware running on too little RAM. It takes skill to operate. Some are more skillful than others.
You could of course counter that by saying that's what you believe. It's paradoxes all the way down.
Thoughts and muscle movements come about through the opening and closing of ion channels that allow information to travel through neurons and for muscle fibers to contract and relax. 'Free will' in the sense that our mind is separate from our body and that it can somehow open those ion channels is a combination of dualism and molecular telekinesis, so I do not believe that, no.
But I do believe that consciousness is an essential emergent property of our brain. What we experience might be the output of a causal prediction engine in our brain that is making a prediction about the immediate sensory experience in a way that we can respond to stimuli before they happen. In that sense, yes, I do believe in free will because that conscious output that I experience is me! This prediction machine is me making predictions and choices.
I think that a materialist framing of free will requires accepting some model of consciousness in which consciousness is not just a weird accident but is a physical phenomenon that is part of us. An essential feature of how our brain works. This is not yet demonstrated (very difficult if not impossible to do so), but I think it is. Then 'free will' and 'a material system following the laws of physics' is no longer a contradiction.
Is the emergent phenomena, consciousness, weak or strong? I think the former, which I think you support, posits a panpsychism and the latter is indistinguishable from magic.
I'm a little confused about the relationship between the causal prediction machine (CPM) and the self. to reiterate, the brain has a causal prediction engine. It's inputs are immediate sensory experience. I assume the causal prediction engines' output is predictions. These predictions are limited to the what the next sensory stimuli might be in response to the recent sensory input. These predictions lead to choices. Or maybe the same as choices.
So these outputs are experienced. And that experience of making predictions is me. Am I the one experiencing the predictions as well?
So this sentence confuses me: "This prediction machine is me making predictions and choices." Am I making the predictions or is it the CPM?
I think that its emergence is weak but I see no resolution to the hard problem of consciousness any time soon, so for the time my opinions about it are ideas that I find compelling and intuitive and not grounded in facts and evidence. Weak emergence does posit some form of pansychism in the sense that sentient-like behavior can emerge in other brains and even that characteristics that we might associate with sentience might emerge from other phenomena present through the universe. But, because of the same reasons that the hard problem is hard, it is also hard to study and learn about these phenomena.
I can try to explain a little better what I meant.
I don't believe we have "free will" in the sense that the mind is separate from the body (dualism) and that it is able to break the laws of physics by altering our physiological processes. I don't think that the non-determinism of quantum mechanics in itself gives us agency, and our mind does not have a mechanism to select how a particular wavev function collapses (not a fan of the Orch OR model).
So, in this traditional sense my answer is "no, we do not have free will"
But I think that the existential crisis and feeling of a lack of agency stems from the model of sentience that one believes. If one rejects dualism, posits that consciousness is an emergent property of the brain, but then ascribes only very loosely a mechanism to consciousness such as 'complex information processing gives rise to consciousness', then sentience appears to be just some unexplained quirk that is not essential and just happens to be there. Combining a lack of dualism and free will with consciousness being a useless quirk is what (I think) creates the existential crisis associated with a lack of free will. I used to fall into this camp of thought and resolved the crisis through a logic such as: "Yeah, there is no free will, living is nice though so I am happy that I can accidentally experience the world".
What pushed me to re-assess this way of thinking originally was reading through a paper about teaching a dish of neurons how to play pong](https://www.cell.com/neuron/fulltext/S0896-6273(22)00806-6). At first it did not make sense to me how one can possibly provide feedback to a group of isolated neurons such that it could learn to play a game. What 'reward' can you give a group of neurons to push them to do what you want?!
I looked into Karl Friston, the last author of that paper, which led me down a path of study. I discovered Judea Pearl, who formalized causal reasoning in a way that lets us build statistical models to move from correlations to counterfactual causes. This makes it possible to teach causal inference even to machines.
Karl Friston's work and other researchers in the field argue that the brain is a computer built for causal computing. This idea underpins the Bayesian brain, Predictive Coding Theory, Active Inference.
In Karl Friston's Active Inference book, sentience is proposed to emerge as a result of the prediction engine. What we experience is not actually what our senses already experienced, but instead it is what our brain expects that we will sense in the next instant. This model of reality that is built by our brain in its attempt to perform its basic function (link causes to effects in order to predict the next stimulus).
One idea is that consciousness emerges because the predictive brain is creating a 'model' that does not exist in physical space and so it needs imagination to explore it. The imagination of things that do not exist is essential to the process of generating counterfactuals, and counterfactuals are at the core of the causality machine. To show that A causes B, you need to imagine a situation in which A is not present and estimate the likelyhood of B. One idea is that it is precisely in the creation of a world without A that sentience emerges.
A lot of these ideas are not falsifiable, so it is difficult to say that this is indeed the mechanism of consciousness. But some of the ideas are falsifiable, and those ideas have helped these researchers teach neurons how to play pong, so I think they might have a point.
So, then, I find it plausible that consciousness is not a quirk but an essential feature of our brain. To me this resolves the free will crisis because my consciousness is not an accidental outcome of physical processes just chaotically whizzing by but an actual feature of the machinery that is me.
So these outputs are experienced. And that experience of making predictions is me. Am I the one experiencing the predictions as well?
So this sentence confuses me: βThis prediction machine is me making predictions and choices.β Am I making the predictions or is it the CPM?
I am this machine and I follow the laws of physics. I am part of physical reality, and my sentience is a feature of who I am. If I do something it is because I chose to do so, and the fact that I chose to do so in accordance to the law of physics does not remove my agency.
"Free will" usually refers to the belief that your decisions cannot be reduced to the laws of physics (e.g. people who say "do you really think your thoughts are just a bunch of chemical reactions in the brain???"), either because they can't be reduced at all or that they operate according to their own independent logic. I see no reason to believe that and no evidence for it.
Some people try to bring up randomness but even if the universe is random that doesn't get you to free will. Imagine if the state forced you to accept a job for life they choose when you turn 18, and they pick it with a random number generator. Is that free will? Of course not. Randomness is not relevant to free will. I think the confusion comes from the fact that we have two parallel debates of "free will vs determinism" and "randomness vs determinism" and people think they're related, but in reality the term "determinism" means something different in both contexts.
In the "free will vs determinism" debate we are talking about nomological determinism, which is the idea that reality is reducible to the laws of physics and nothing more. Even if those laws may be random, it would still be incompatible with the philosophical notion of "free will" because it would still be ultimately the probabilistic mathematical laws that govern the chemical reactions in your brain that cause you to make decisions.
In the "randomness vs determinism" debate we are instead talking about absolute determinism, sometimes also called Laplacian determinism, which is the idea that if you fully know the initial state of the universe you could predict the future with absolute certainty.
These are two separate discussions and shouldn't be confused with one another.
