Three possibilities come to mind:

Is there an evolutionary purpose?

Does it arise as a consequence of our mental activities, a sort of side effect of our thinking?

Is it given a priori (something we have to think in order to think at all)?

EDIT: Thanks for all the responses! Just one thing I saw come up a few times I’d like to address: a lot of people are asking ‘Why assume this?’ The answer is: it’s purely rhetorical! That said, I’m happy with a well thought-out ‘I dispute the premiss’ answer.

    Confabulation.

    Look at split-brain patients: divide the corpus callosum down the middle, and you effectively have two separate brains that don’t communicate. Tell the half without the speech centre to perform some random task, then ask the other one why they did that - and they will flat-out make up some plausible sounding reason.

    And the thing is, they haven’t the slightest idea that it isn’t true. To them, it feels exactly like freely choosing to do it, for those made up reasons.

    Bits of our brains make us do stuff for their own reasons, and we just make shit up to explain it after the fact. We invent the memory of choosing, about a quarter of a second after we’ve primed our muscles to carry out the choice.

    I think a chunk of this comes down to our need to model the thoughts of others (incredibly useful for social animals) - we make everyone out to be these monolithic executive units so that we can predict their actions, and we make ourselves out to be the same so we can slot ourselves into that same reasoning.

    Also it would be a bit fucking terrifying to just constantly get surprised by your own actions, blown around like a leaf on the wind without a clue what’s going on, so I think another chunk of it is just larping this “I” person who has a coherent narrative behind it all, to protect your own sanity.

    There was a relevant post on Lemmy the other day:

    The origin and nature of existence is an epistemological black hole that some people like to plug with “a wizard god did it”.

    The sensation of free will is an emergent property of a lack of awareness of the big stuff, the small stuff, the long stuff, and the short stuff.

      I like to look at the illusion of free will as if you’re falling down a pit. You can try to flap your arms or swim, and maybe move yourself a little bit, but at the end, you’re still falling down.

      Warning, I came up with this while very high one time, lol, but it’s kind of stuck with me:

      Consciousness is a 4-dimensional construct living in a 3-dimensional world. What we experience as the passage of time is just our consciousness traveling/falling along the surface of the 4-dimensional plane/shape that defines our existence.

      Feel free to poke all the holes you want in that. lol

        There is an old Taoist story about two people floating down a river. One has already decided where he wants the river to take him and is constantly swimming against the current to try to get there, the other just floats along taking in the sights.

        They both end up wherever the river takes them, and they both went through the same obstacles and rapids, but when asked how the trip was, one of them is complaining about the whole trip being frustrating and exhausting, while the other had a pleasant time and tells you all about the amazing things they saw on the way.

    Here’s my take: the answer is emergent phenomena. We live in a very complex system and in complex systems there are interactions that can only be predicted using systems of equal or higher complexity. So even in case everything is predetermined, it would still be unpredictable and therefore your decisions are basically still up to you and the complex interactions in your brain.

      I think this is probably it. I think this argument is strongly related to the idea of consciousness as an emergent property of sensory experience. I find it simple to imagine the idea of a body with no will or no consciousness (i.e., a philosophical zombie). But I find it very difficult, almost impossible, in fact, to imagine a consciousness with no will, even if it’s only the will to think a given thought.

            My thoughts would be presented based the fact that you’ve asked me to calculate something. At that point, past experiences would guide my path forward. If I felt like doing math, I may do it, if I had poor childhood experiences in math class, I probably wouldn’t. At the end of the day, it’s all based on history or current questions/feelings. In every scenario my thoughts are presented to me. To prove it, ask yourself what your next thought will be. If you’re honest with yourself, you’ll see you can’t answer that question and when you try and force a thought direction, that direction itself is based on your knowledge from the past and that thought was also presented to you.

            It’s wild because it absolutely feels like we have free will, but it sure doesn’t look like it. 🤷‍♂️

              This is the problem of original intentionality. There are studies on it, for instance they found that with an mri they can detect when you have come to a decision before your conscious mind realizes you have. Some processes in our brain are outside of our control, because the brain is not just the neocortex but also includes tens of other structures that evolved separately with specific hard-coded purposes, but that doesn’t mean they are not working as a team. I think in any case you are still reaponsible for the decisions you take.

    Our brains cannot store all the experiences we ever make. It rather only stores ‘hunches’ (via many weightings of neurons). In particular, it also mixes multiple experiences together to reinforce such hunches.

    This means that despite there being causal reasons why you might e.g. feel uneasy around big dogs, your brain will likely only reproduce a hunch, a gut feeling of fear.

    And then because you don’t remember the concrete causal reasons, it feels like a decision to follow your hunch to get the hell out of there.
    This feeling of making a decision is made even stronger, because there isn’t just the big-dog-bad-hunch, but also the don’t-show-fear-to-big-dog-hunch and the I’m-in-a-social-situation-and-it-would-be-rude-to-leave-hunch and many others.

    There is just an insane amount of past experiences and present sensory input, which makes it impossible to trace back why you would decide a certain way. This gives the illusion of there being no reasons, of free will.

    Roger Penrose is pretty much the only dude looking into consciousness from the perspective of a physicist

    He thinks consciousness has to do with “quantum bubble collapse” happening inside our brains at a very very tiny level.

    That’s the only way free will could exist.

    If consciousness is anything else, then everything is predetermined.

    Like, imagine dropping a million bouncy balls off the hoover dam. You’ll never get the same results twice.

    However, that’s because you’ll never get the same conditions twice.

    If the conditions are exactly the same down to an atomic level… You’ll get the same results every time

    What would give humans free will would be the inherent randomness if the whole “quantum bubble collapse” was a fundamental part of consciousness.

    That still wouldn’t guarantee free will, but it would make it possible.

    There’s also the whole thing where what we think of as our consciousness isn’t actually running the show. It’s just a narrator that’s summarizing everything up immediately after it happened. What’s actually calling the shot is other parts of our brains, neurons in our gut, and what controls our hormones.

    We don’t know if that’s not true either. But if it was, each person as a thing would have free will, it’s just what we think of as that person does not have free will.

    Sounds batshit crazy and impossible, until you read up on the studies on people who had their brains split in half at different stages of mental development.

    There’s a scary amount of shit we don’t know about “us”. And an even scarier amount we don’t know about how much variation there is with all that

      Roger Penrose is pretty much the only dude looking into consciousness from the perspective of a physicist

      I would recommend reading the philosophers Jocelyn Benoist and Francois-Igor Pris who argue very convincingly that both the “hard problem of consciousness” and the “measurement problem” stem from the same logical fallacies of conflating subjectivity (or sometimes called phenomenality) with contextuality, and that both disappear when you make this distinction, and so neither are actually problems for physics to solve but are caused by fallacious reasoning in some of our a priori assumptions about the properties of reality.

      Benoist’s book Toward a Contextual Realism and Pris’ book Contextual Realism and Quantum Mechanics both cover this really well. They are based in late Wittgensteinian philosophy, so maybe reading Saul Kripke’s Wittgenstein on Rules and Private Language is a good primer.

      That’s the only way free will could exist…What would give humans free will would be the inherent randomness if the whole “quantum bubble collapse” was a fundamental part of consciousness.

      Even if they discover quantum phenomena in the brain, all that would show is our brain is like a quantum computer. But nobody would argue quantum computers have free will, do they? People often like to conflate the determinism/free will debate with the debate over Laplacian determinism specifically, which should not be conflated, as randomness clearly has nothing to do with the question of free will.

      If the state forced everyone into a job for life the moment they turned 18, but they chose that job using a quantum random number generator, would it be “free”? Obviously not. But we can also look at it in the reverse sense. If there was a God that knew every decision you were going to make, would that negate free will? Not necessarily. Just because something knows your decision ahead of time doesn’t necessarily mean you did not make that decision yourself.

      The determinism/free will debate is ultimately about whether or not human decisions are reducible to the laws of physics or not. Even if there is quantum phenomena in the brain that plays a real role in decision making, our decisions would still be reducible to the laws of physics and thus determined by them. Quantum mechanics is still deterministic in the nomological sense of the word, meaning, determinism according to the laws of physics. It is just not deterministic in the absolute Laplacian sense of the word that says you can predict the future with certainty if you knew all properties of all systems in the present.

      If the conditions are exactly the same down to an atomic level… You’ll get the same results every time

      I think a distinction should be made between Laplacian determinism and fatalism (not sure if there’s a better word for the latter category). The difference here is that both claim there is only one future, but only the former claims the future is perfectly predictable from the states of things at present. So fatalism is less strict: even in quantum mechanics that is random, there is a single outcome that is “fated to be,” but you could never predict it ahead of time.

      Unless you ascribe to the Many Worlds Interpretation, I think you kind of have to accept a fatalistic position in regards to quantum mechanics, mainly due not to quantum mechanics itself but special relativity. In special relativity, different observers see time passing at different rates. You can thus build a time machine that can take you into the future just by traveling really fast, near the speed of light, then turning around and coming back home.

      The only way for this to even be possible for there to be different reference frames that see time pass differently is if the future already, in some sense, pre-exists. This is sometimes known as the “block universe” which suggests that the future, present, and past are all equally “real” in some sense. For the future to be real, then, there has to be an outcome of each of the quantum random events already “decided” so to speak. Quantum mechanics is nomologically deterministic in the sense that it does describe nature as reducible to the laws of physics, but not deterministic in the Laplacian sense that you can predict the future with certainty knowing even in principle. It is more comparable to fatalism, that there is a single outcome fated to be (that is, again, unless you ascribe to MWI), but it’s impossible to know ahead of time.

        Even if they discover quantum phenomena in the brain

        There 100% are…

        Penrose thinks they’re responsible for consciousness.

        Because we also don’t know what makes anesthesia stop consciousness. And anesthesia stops consciousness and stops the quantum process.

        Now, the math isn’t clean. I forget which way it leans, but I think it’s that consciousness kicks out a little before the quantum action is fully inhibited?

        It’s been a minute, and this shit isn’t simple.

        Unless you ascribe to the Many Worlds Interpretation

        This is incompatible with that.

        It’s the quantum wave function collapse that’s important. There’s no spinning out where multiple things happen, there is only one thing. After wave collapse, is when you look in the box and see if the cats dead.

        In a sense it’s the literal “observer effect” happening our head.

        And that is probably what consciousness is.

        It’ll just take a while till we can prove it. And Penrose will probably be dead by then. But so was Einstein before Penrose proved most of his shit was true

          I don’t think it’s incompatible with many worlds, unless I’m misunderstanding something. The many worlds interpretation means that the observer doesn’t collapse the wave function, but rather becomes entangled with it. It only apparently collapses because we only perceive a “slice” of the wave function. (For whatever reason).

          I think this is still compatible with Penrose’s ideas, just not in the way he presents it. Anyway, I think he’s not really explaining consciousness, but rather a piece of how it could be facilitated in the brain.

          If you choose to believe so, like I said I don’t really care. Is a quantum computer conscious? I think it’s a bit irrelevant whether or not they exist. I will concede they do for the sake of discussion.

          Penrose thinks they’re responsible for consciousness.

          Yeah, and as I said, Penrose was wrong, not because the measurement problem isn’t the cause for consciousness, but that there is no measurement problem nor a “hard problem.” Penrose plays on the same logical fallacies I pointed out to come to believe there are two problems where none actually exist and then, because both problems originate from the same logical fallacies. He then notices they are similar and thinks “solving” one is necessary for “solving” the other, when neither problems actually existed in the first place.

          Because we also don’t know what makes anesthesia stop consciousness. And anesthesia stops consciousness and stops the quantum process.

          You’d need to define what you mean more specifically about “consciousness” and “quantum process.” We don’t remember things that occur when we’re under anesthesia, so are we saying memory is consciousness?

          Now, the math isn’t clean. I forget which way it leans, but I think it’s that consciousness kicks out a little before the quantum action is fully inhibited? It’s been a minute, and this shit isn’t simple.

          Sure, it’s not simple, because the notion of “consciousness” as used in philosophy is a very vague and slippery word with hundreds of different meanings depending on the context, and this makes it seem “mysterious” as its meaning is slippery and can change from context to context, making it difficult to pin down what is even being talked about.

          Yet, if you pin it down, if you are actually specific about what you mean, then you don’t run into any confusion. The “hard problem of consciousness” is not even a “problem” as a “problem” implies you want to solve it, and most philosophers who advocate for it like David Chalmers, well, advocate for it. They spend their whole career arguing in favor of its existence and then using it as a basis for their own dualistic philosophy. It is thus a hard axiom of consciousness and not a hard problem. I simply disagree with the axioms.

          Penrose is an odd case because he accepts the axioms and then carries that same thinking into QM where the same contradiction re-emerges but actually thinks it is somehow solvable. What is a “measurement” if not an “observation,” and what is an “observation” if not an “experience”? The same “measurement problem” is just a reflection of the very same “hard problem” about the supposed “phenomenality” of experience and the explanatory gap between what we actually experience and what supposedly exists beyond it.

          It’s the quantum wave function collapse that’s important.

          Why should I believe there is a physical collapse? This requires you to, again, posit that there physically exists something that lies beyond all possibilities of us ever observing it (paralleling Kant’s “noumenon”) which suddenly transforms itself into something we can actually observe the moment we try to look at it (paralleling Kant’s “phenomenon”). This clearly introduces an explanatory gap as to how this process occurs, which is the basis of the measurement problem in the first place.

          There is no reason to posit a physical “collapse” or even that there exists at all a realm of waves floating about in Hilbert space. These are unnecessary metaphysical assumptions that are purely philosophical and contribute nothing but confusion to an understanding of the mathematics of the theory. Again, just like Chalmers’ so-called “hard problem,” Penrose is inventing a problem to solve which we have no reason to believe is even a problem in the first place: nothing about quantum theory demands that you believe particles really turn into invisible waves in Hilbert space when you aren’t looking at them and suddenly turn back into visible particles in spacetime when you do look at them.

          That’s entirely metaphysical and arbitrary to believe in.

          There’s no spinning out where multiple things happen, there is only one thing. After wave collapse, is when you look in the box and see if the cats dead. In a sense it’s the literal “observer effect” happening our head. And that is probably what consciousness is.

          There is only an “observer effect” if you believe the cat literally did turn into a wave and you perturbed that wave by looking at it and caused it to “collapse” like a house of cards. What did the cat see in its perspective? How did it feel for the cat to turn into a wave? The whole point of Schrodinger’s cat thought experiment was that Schrodinger was trying to argue against believing particles really turn into waves because then you’d have to believe unreasonable things like cats turning into waves.

          All of this is entirely metaphysical, there is no observations that can confirm this interpretation. You can only justify the claim that cats literally turn into waves when you don’t look at them and there is a physical collapse of that wave when you do look at them on purely philosophical grounds. It is not demanded by the theory at all. You choose to believe it purely on philosophical grounds which then leads you to think there is some “problem” with the theory that needs to be “solved,” but it is purely metaphysical.

          There is no actual contradiction between theory and evidence/observation, only contradiction between people’s metaphysical assumptions that they refuse to question for some reason and what they a priori think the theory should be, rather than just rethinking their assumptions.

          That’s how science works. Most won’t know who Penrose is till he’s dead.

          I’d hardly consider what Penrose is doing to be “science” at all. All these physical “theories of consciousness” that purport not to just be explaining intelligence or self-awareness or things like that, but more specifically claim to be solving Chalmers’ hard axiom of consciousness (that humans possess some immaterial invisible substance that is somehow attached to the brain but is not the brain itself), are all pseudoscience, because they are beginning with an unreasonable axiom which we have no scientific reason at all to take seriously and then trying to use science to “solve” it.

          It is no different then claiming to use science to try and answer the question as to why humans have souls. Any “scientific” approach you use to try and answer that question is inherently pseudoscience because the axiomatic premise itself is flawed: it would be trying to solve a problem it never established is even a problem to be solved in the first place.

              No, we don’t know the brain is making use of any quantum phenomena. At best if there is any quantum phenomena in the brain it would just contribute noise. The idea that interference phenomena is actually made use of in the brain for computation is just not backed by anything.

            I agree with some of what you’re saying, but can you explain (in simple terms please) how the hard problem doesn’t exist? I’m not quite following. The subjective experience of consciousness is directly observable, and definitely real, no?

            (I don’t think adding some metaphysical element does much of anything, and Penrose still doesn’t really explain it, just provides a potential mechanism for it in the brain. It’s still a real “thing”, unexplained by current physics though.)

            Also, to your other point, my I believe everything is just an evolving wave function. All waves all the time, and we only perceive a slice of it. (Which has something to do with consciousness, but nobody really knows exactly how). The Copenhagen interpretation is just how the many worlds universe appears to behave to a conscious observer.

              The subjective experience of consciousness is directly observable, and definitely real, no?

              Experience is definitely real, but there is no such thing as “subjective experience.” It is not logically possible to say there is “subjective experience” without inherently entailing that there is some sort of “objective experience,” in the same way that saying something is “inside of” something makes no sense unless there is an “outside of” it. Without implicitly entailing some sort of “objective experience” then the qualifier “subjective” would become meaningless.

              If you associate “experience” with “minds,” then you’d be implying there is some sort of objective mind, i.e. a cosmic consciousness of some sorts. Which, you can believe that, but at that point you’ve just embraced objective idealism. The very usage of the term “subjective experience” that is supposedly inherently irreducible to non-minds inherently entails objective idealism, there is no way out of it once you’ve accepted that premise.

              The conflation between experience with “subjectivity” is largely done because we all experience the world in a way unique to us, so we conclude experience is “subjective.” But a lot of things can be experienced differently between different observers. Two observers, for example, can measure the same object to be different velocities, not because velocity is subjective, but because they occupy different frames of reference. In other words, the notion that something being unique to us proves it is “subjective” is a non sequitur, there can be other reasons for it to be unique to us, which is just that nature is context-dependent.

              Reality itself depends upon where you are standing in it, how you are looking at it, everything in your surroundings, etc, how everything relates to everything else from a particular reference frame. So, naturally, two observers occupying different contexts will perceive the world differently, not because their perception is “subjective,” but in spite of it. We experience the world as it exists independent of our observation of it, but not independent of the context of our observation. Experience itself is not subjective, although what we take experience to be might be subjective.

              We can misinterpret things for example, we can come to falsely believe we experienced some particular thing and later it turns out we actually perceived something else, and thus were mistaken in our initial interpretation which we later replaced with a new interpretation. However, at no point did it become false that there was experience. Reality can never be true or false, it always just is what it is. The notion that there is some sort of “explanatory gap” between what humans experience and some sort of cosmic experience is just an invented problem. There is no gap because what we experience is indeed reality independent of conscious observers being there to interpret it, but absolutely dependent upon the context under which it is observed.

              Again, I’d recommend reading Jocelyn Benoist’s Toward a Contextual Realism. All this is explained in detail and any possible rebuttal you’re thinking of has already been addressed. People are often afraid of treating experience as real because they operate on this Kantian “phenomenal-noumenal” paradigm (inherently implied by the usage of “subjective experience”) and then think if they admit that this unobservable “noumenon” is a meaningless construct then they have to default to only accepting the “phenomenon,” i.e. that there’s only “subjective experience” and we’re all “trapped in our minds” so to speak. But the whole point of contextual realism is to point out this fear is unfounded because both the phenomenal and noumenal categories are problematic and both have to be discarded: experience is not “phenomenal” as a “phenomenal” means “appearance of reality” but it is not the appearance of reality but is reality.

              You only enter into subjectivity, again, when you take reality to be something, when you begin assigning labels to it, when you begin to invent abstract categories and names to try and categorize what you are experiencing. (Although the overwhelming majority of abstract categories you use were not created by you but are social constructs, part of what Wittgenstein called the “language game.”)

              (I don’t think adding some metaphysical element does much of anything, and Penrose still doesn’t really explain it, just provides a potential mechanism for it in the brain. It’s still a real “thing”, unexplained by current physics though.)

              We don’t need more metaphysical elements, we need less. We need to stop presuming things that have no reason to be presumed, then presuming other things to fix contradictions created by those false presumptions. We need to discard those bad assumptions that led to the contradiction in the first place (discard then phenomenal-noumenal distinction entirely, not just one or the other).

              Also, to your other point, my I believe everything is just an evolving wave function.

              This is basically the Many Worlds Interpretation. I don’t really buy it because we can’t observe wave functions, so if the entire universe is made of wave functions… how does that explain what we observe? You end up with an explanatory gap between what we observe and the mathematical description.

              The whole point of science is to explain the reality which we observe, which is synonymous with experience, which again experience just is reality. That’s what science is supposed to do: explain experiential reality, so we have to tie it back to experience, what Bell called “local beables,” things we can actually point to identify in our observations.

              The biggest issue with MWI is that there is simply no way to tie it back to what we actually observe because it contains nothing observable. There is an explanatory gap between the world of waves in Hilbert space and what we actually observe in reality.

              The Copenhagen interpretation is just how the many worlds universe appears to behave to a conscious observer.

              What you’ve basically done is just wrapped up the difficult question of how the invisible world of waves in Hilbert space converts itself to the visible world of particles in spacetime by just saying “oh it has something to do with our consciousness.” I mean, sure, if you find that to be satisfactory, I personally don’t.

          There are quantum phenomenon in a piece of bread. That doesn’t mean bread is conscious.

          Penrose has never proved that the quantum effects affect neurons macroscopically.

          Quantum computers run at near absolute zero temperature and isolated from all vibrations in order to maintain superposition. The brain is a horrible environment for a quantum computer.

          Anesthesia is a chemical signal blocker. If consciousness was quantum, it couldn’t affect it.

          Penrose’s work is “God in the gaps” or in his case “quantum in the gaps” explanation of consciousness. His claims were made before we had functional quantum computers and precise categorization of neurotransmitters that anesthesia chemicals bind to to block your natural neurotransmitters.

    You’re conscious of the decisions you make. Sure they’re the result of a million different variables, chemicles, memories, and predetermined traits, but some of that is active. You are making the choice. Whether you could have made a different one or not doesn’t affect what the choice feels like

    Because it’s not an illusion.

    Determinism seems reasonable only because people have an inaccurately simplistic conception of causation, such that they believe that consciousness and choice violate it, rather than being a part of it.

    Causation isn’t a simple linear thing - it’s an enormously complex web in which any number of things can be causes and/or effects of any number of things.

    Free will (properly understood) is just one part of that enormously complex web.

          Even in that scenario, the “conscious choice” happened via some particular arrangement of neurons/chemical messengers/etc. Your argument is a “god of the gaps” argument- science doesn’t know everything about how the brain works, therefore some supernatural process called “free will” is the cause of the stuff science can’t explain yet.

            god of the gaps

            supernatural

            Without those obvious pejoratives, that would’ve been a pretty good summation of at least that aspect of my position.

            With those obvious pejoratives, it was reduced to an unfortunate expression of bias.

            I believe that it’s not simply that science doesn’t yet fully understand how the brain works, but that it’s not even really equipped to deal with consciousness, which while clearly a manifestation of physical processes, is not itself physical.

            That and we’re in an era in which “science” (scare quotes because part of the problem IMO is a misunderstanding of what science can do and does) has largely moved to the forefront of the pursuit of understanding, but humanity is still to some significant degree stuck in a quasi-religious mindset, so all too many have merely shifted from a devout faith that their religion provides every answer to everything ever to a devout faith that “science” provides every answer to everything ever.

            The problem then comes when they run up against something for which science can’t provide an answer. And the common response then is to blithely insist that that thing must not and cannot exist at all, since the alternative is to face the fact that science potentially cannot provide every answer to everything ever. And that’s generally accompanied by an immediate assignment of whatever it is that’s in question to the other half of their wholly binaristic worldview - if it’s not amenable to science, it must and can only be religion/magic.

            Reality, IMO, is vaster than that.

          I agree that it “seems to be the case” that we consciously choose, but I don’t understand where you found justification to state that there really are such points. How do you dismiss the idea that our conscious choice is not simply an application of the myriad parameters?

            I don’t understand where you found justification to state that there really are such points.

            Because I experience them, and not just at times, but moment-to-moment, every waking day. And so do you. And so does essentially every single human in existence.

            That indicates two possibilities - either it’s a universal illusion, and in both senses of the term - one experienced by everyone and one experienced without exception by each individual, or it’s a real experience.

            And I just find the former to be so ridiculously unlikely that the latter can be safely said to be near certainly true.

            How do you dismiss the idea that our conscious choice is not simply an application of the myriad parameters?

            I don’t. I simply include consciousness, and all it entails - reason, value, self-interest, preference, mood, etc. - among those parameters.

              Or, as you acknowledged before, it seems like you experience them. That experience of weighing up all the inputs, applying your mood and whatever else you bring, feels like making a decision freely.

              I simply include consciousness, and all it entails - reason, value, self-interest, preference, mood, etc. - among those parameters.

              These parameters are all examples of the complex inputs that precede a decision. And each of these inputs could be understood as the inevitable result of a causal chain.

              It’s super complex and likely involves technology that we don’t yet possess, but if I could perfectly simulate a brain identical to yours, with the same neural states, and the same concentrations of relevant chemicals in its simulated blood at the moment of the decision, that simulated brain would have to produce the same output as as your meaty one.

                Yes.

                If I’m to be precise, it seems that I exist on what seems to be a planet in what seems to be a universe. On that seeming planet it seems as if I am surrounded by what seem to be things - some of which seem to be alive and others of which seem not to be. And among the ones that seem to be alive, there are some that seem to share the classification I seem to possess, as a human being.

                In my seeming experience as what seems to be accurately desgnated a human being, I seem to experience some things, among them the process of seeming to make choices. And that process of seeming to make choices is a thing that I seemingly perceive the other seeming humans who seem to exist seemingly relate to be a part of their seeming lives as well.

                And so on. Since I, as seems to be the case with all other beings that seem to exist, live behind the veil of perception, I cannot know for certain that any part of what I experience represents an objective reality. So every single aspect of my experience of life, most accurately, can only be said to seem to be as I perceive it to be.

                And each of these inputs could be understood as the inevitable result of a causal chain.

                I simply don’t believe that to be the case, if for no other reason than that that would appear to make creative reasoning impossible. If reason was merely the manifestation of a rigid causal chain, then all reason would follow the same paths to the same destinations. The fact that human history is, viewed one way, a record of new chains being followed to new destinations, means that there must be some mechanism by which consciousness can and does effectively “switch tracks.” Or even introduce entirely new ones.

                It’s super complex and likely involves technology that we don’t yet possess, but if I could perfectly simulate a brain identical to yours, with the same neural states, and the same concentrations of relevant chemicals in its simulated blood at the moment of the decision, that simulated brain would have to produce the same output as as your meaty one.

                Nor do I believe that to be true, since while consciousness appears to be a manifestation of the mechanical workings of the brain, it is not itself merely those mechanical workings - it is a “thing” unto itself. And I believe, quite simply, that the relationship between consciousness and the brain is not unidirectional, but bidirectional - that just as the physical state of a brain can be a proximate cause of a chain of thought, a chain of thought can be a proximate cause of a physical state of a brain.

                And in fact, I would say that that’s easily demonstrated by the fact that one can trigger a response - fight or flight for instance - merely by imagining a threat. There’s no need for any physical manifestation of the threat - a wholly conscious, wholly non-physical imagining of it is sufficient. That says to me, rather clearly, that consciousness can serve as a cause - not merely as an effect.

                And on a side note, thanks for the responses - this subject particularly fascinates me, but I find intellectually honest debate on it to be vanishingly rare.

                  You’re welcome. I too find it very interesting, though my expertise in it is below amater level.

                  I am a little confused about your model of continuous and the brain: you speak of consciousness appearing to be a manifestation of the brain’s processing, but talk about what seems to be a communicative relationship between the two. My understanding is that consciousness is entirely an emergent property of the brain, impossible to distinguish from the squishy mechanics. If yours is significantly different to this, then it is no wonder that our beliefs diverge.

  • I forget which philosopher said this but he said something along the lines of if you have the desire and the capacity for an action you do, then deterministic or not, you chose that action. If the tide pulls me where I was already swimming, I still chose to swim there, even if some other force took me half of the way.

    I personally think the debate over the existence of Free Will is simply an extraordinary debate over semantics.

    If you look at a human being from its basic biological and cellular makeup, a human being is a walking bundle of competing desires that appears to present itself as a single cohesive corporate entity.

    The people who are against the concept of free will say that because you have innate desires for food sex and entertainment, that you have no choice to not act upon those in a desires and therefore any delusion that you carry about the choices that you make being done of an entirely unencumbered and Free Will are false.

    Then there are people who say that Free Will doesn’t exist for religious purposes, that God is an all-knowing creature who knows the beginning and the end and everything in between and so you cannot make a choice that he or she or it does not already know that you will make and therefore your choices are not free.

    The people who say Free Will does exist on a biological level will point to people who choose to self-immolate or to starve themselves to death in protest of a spiritual or psychological issue, valuing the ideals that life has imprinted upon them over the biological necessities of continuing to live.

    The people who say Free Will does exist on a spiritual level say many things, such as we carry a spark of the Divine in us and therefore we are as little gods ourselves, capable of creating and destroying in roughly the same proportional magnitude as the greater gods above are, or they say that since we have the ability to make choices and we are judged by those choices than our choices must be free otherwise judgment is meaningless.

    I personally tend to lean into the Free Will side, while understanding simultaneously that sometimes there are exigencies that induce us to choose one option over another on a more likely than not basis, or to phrase it another way, our will is as free as we choose it to be.

      That’s not the argument against free will. The argument is just that there’s a physical process to every thought in your head. When you think of a tree, inside your brain a specific pattern of neurons and chemical messengers activate which is what creates the thought of a tree.

      When you’re consciously deciding whether to eat a donut or a salad, a specific pattern of neurons and chemical messengers are the mechanism by which that decision process is occurring. The pattern of neurons and chemical messengers happening in your brain is the physical mechanism that is performing the decision making process.

      There are no thoughts outside of the ones generated by your neurons and chemical messengers. The pattern of neurons and chemical messengers IS the thought that you’re thinking. Your brain (and the thoughts that occur within it) is a physical object that obeys the laws of nature, the same as all physical objects do.

    Just going to throw out a really good read: Determined by Robert Sapolky. (Behave is also really good.)

    He doesn’t really convince me of the core thesis that free will doesn’t exist, or that some of his proposed changes to the legal system to “recognize the absence of free will” in the second half are good courses of action, but he does do a great job of demonstrating what makes us tick from a variety of lenses, how much environmental factors play a role in behavior, and generally arguing to approach people with more empathy and recognition that we might be more like them in a similar situation than we think.

    (It is heavy. It’s long and goes into some depth on different fields. But he lays out the main ideas you need to know and doesn’t assume that much knowledge, just a will to learn.)

      • I read a fucking lot of books about what makes us tick. Behave is (tied for) my favorite. He does actually hint down the determinism path a little in behave, but he goes all in on Determined.

        I would still probably generally recommend Behave over Determined, but Determined is directly relevant to the OP.
