@Society Destroyer being taught how to think is fundamentally how education works. You don’t want to teach information because we do not retain it well; you want to teach algorithms or constructs that allow you to think in ways that you would have never thought had you not learned that skill. For instance, Machining. All the information for any machine job can be calculated by a calculator and ran independently of a person. The issue where machinists come in is when abstract concepts that adhere to multiple possible substrates of logic that could reasonably determine the correct result and how to make it. In machine class they teach you how to think like a machinist so you can machine. Just because you’re a competent person who can read manuals and apply math doesn’t mean you can just decide to be a machinist; however conversely, it is possible for someone to develop these skills on their own, as how else would we derive the systems? But to say that we should not allow another to influence how we think is the same as saying we should have the same lives we did as cavemen. We build on the foundation left by our predecessors.

Food for thought: If a cosmic gamma ray from a hawking pair nearby an event horizon activated a neuronal pathway when your muscles were launching the coin, causing it to spin at a slightly different speed and to a larger height, would that not be considered sufficiently of random origin to constitute free will? If an apparently random quantum decay damaged a neuron, causing you to spontaneously choose a coin toss versus having a passive statistical distribution laid out in your neural network, could that be considered free will? Does the existence of ionizing neutrino radiation, being hitherto unshieldable in any feasibility, rule out the concept of controllable determinism in any advanced intelligence system? Should we build a simulation where naturally occurring intelligent agents have all the characteristic properties which we enjoy, including free will?

Probably the strangest situation is when you preform an action, seemingly by free will, and then you think back on your own history to find the events in your life that would've led up to such an action. With or without free will, we are ultimately products of our environment, and had I grown up in a different environment, even if I had the same genetics, I would've made very different choices due to experiencing different situations. Sometimes a chance happening somewhere can change your fate in a way far beyond what mere choice alone could do without that luck.

[@gabrote42]

I think about how I came to like the game Omori, with a simplified causal chain of 60 elements from the first "thoughtless curiosity of a 2 year old" about a computer, in the shower. The trick is that the only downside of acting like you have free will (and not spreading that knowledge unprompted) is that mass media can manipulate you a little easier, and it comes with good benefits like morale in the face of a bad situation and encouraging critical thought. I don't know what definition of free will I am in possession of, but I pretend that I have one if I don't, and exercise it if I do. Easy.

[@tomc.5704]

One of the most fascinating things to me is that despite all we have learned about the world, we are still no closer to settling the debate on free will. For a while, it looked like determinism was going to be the clear winner. But now quantum physics and the nature of consciousness have shaken things up. Maybe we'll never know. Maybe it's ambiguous. Maybe there's always another layer, and sometimes it will look deterministic, sometimes it won't. Maybe it's turtles all the way down.

Put everything to the test and hold fast to that which is good. People need to read the Bible for themselves and let the Bible interpret the Bible. It's the ONLY book EVER written that stated that everything detectable is MADE FROM THAT WHICH IS UNDETECTABLE. Scientists have discovered this recently. So using their own limited intelligents they surmise that the universe came from NOTHING. How Stupid is that? The Bible is the ONLY book EVER WRITTEN that stated that the universe had a beginning, has FIXED laws of physics, is expanding, and has a CAUSAL AGENT OUTSIDE OF ENERGY MATTER SPACE AND TIME. The latest spacetime theorems state that ANY UNIVERSE LIKE OURS MUST HAVE A CAUSAL AGENT OUTSIDE OF ENERGY MATTER SPACE AND TIME because all have a beginning just as the Bible stated VERY CLEARLY. The Bible also gets all the conditions and sequence of Creation events 100% correct. No OTHER book COMES close. The Old Testament PROPHECISED the birth life ministry and death of Jesus Christ and the New Testament fulfilled those PROPHECIES exactly as PROPHECISED! Only God knows the end from the beginning. Time to wake UP to the truth before it's too late. Jesus Christ FORETOLD many events that came to pass exactly as PROPHECISED. He said he is coming back and all the signs that He TOLD US to watch for, are happening right now. He said when we 'SEE' THESE SIGNS, know that He is at the door. The generation that SEES THESE SIGNS WILL NOT PASS AWAY BEFORE HE RETURNS. If all the other Prophecies have come to pass and they have, surely This Prophecy will also. MARANATHA.

Another killer episode! SpaceTime's been cranking out some bangers. When Matt was talking about "emergent phenomenon, conscious free-will can recursively influence the machine itself", that was some powerful stuff and reminds me of those people who say "Computers can only do what we tell them" and little do those people realize that self-modifying programs are pretty much Artificial Intelligence 101. I also like how, on a previous episode about determinism, you essentially related the relativistic block-universe to the quantum many-worlds and that's cool because I had a serious misunderstanding that the many-world somehow meant, every future and that's not true, it's "every _possible_ future" and that's a much different landscape of reality.

When I was very little I could enter sometimes in some very peculiar state of mind. It feels like a deja vu but isn't. It started with the question "what happened if I chose another action?" that popped in my mind every time I did something, anything, even moving a part of my body. "What happened if I chose differently? Would the future be the same? Do my actions have a domino effect going indeffinitely?" I knew nothing then about physics or quantum mechanics but it bugged me so bad. It got so intense that I felt tired when it was over. It's safe to say that now, 20 years later I still can't answer those questions satisfyingly

[@gabrote42]

Standing policy for me is that wether or not I COULD have chosen differently, I would not want to gamble with my whole life. I mean, if a single choice a decade back can just leave me in a similar world but with half my friends and an addiction, then it's no deal.

Excellent discussion. I love the example of an apple's atoms not having redness or "appleness". Emergence in Systems Thinking/Systems Theory, the idea that a system can have properties that it's parts do not have, is key to this debate. The brain is not randomly processing information in a random way. It evolved to solve problems and make decisions that increased the chances of surviving long enough to pass genes onto the next generation. Each individual calculation by the brain is driven by deterministic laws of physics, but they all align to the state or memory of the system. Your brain has a mental model of yourself, the world around you and your place in it. A cosmic ray might might hit one of your neurons and cause a cascade of effects that pops a strange idea into your head. But if that idea doesn't conform to your values, beliefs and world view it will be dismissed. Our behaviour isn't random and it is justifiable to say we make decisions of our own volition without denying the deterministic nature of the parts that generated that outcome.

​@@antares-the-one ​ Why such angry response? Perhaps you misunderstood what I mean by "freedom". I mean it in the way Matt presented it in the beginning of this video: being the author of your choices (as opposed to your choices being predefined, or being determined by a random coin flip). If no deterministic process and no indeterministic process leaves room for such freedom, it doesn't matter how much randomness you have. And Matt agrees. And the reason I said that randomness decreases reliability of choices is because I'd rather know for certain that I won't randomly choose to punch myself in the face, a more deterministic decision making process is more trustworthy. Later in his video Matt plays with a different way to define free will, but - as Sabine Hossenfelder put it - this is just verbal acrobatics. I'd rather call deterministic unpredictability by it's name, rather than attaching the label "free will" to it just to have something I can call "free will". This definition of "free will" has no value. I recommend you watch Sabine Hossenfelder's video on free will, I agree with her entirely and she explains it much better than me.

Absolutely brilliant, the uncertainty principle blows my mind.

Budhists dont really say that. (With respect) They say that by observing the mind and by using awareness you escape samsara and enter nirvana. Samsara is cycle of life and death. So using those things you get no body, no brain, no mind etc whatsoever. The only reason why they dont promote suicide is because they beleive it makes things worse in the next life, otherwise without that trigger it would be perfect.

@@Aquillyne Yeah, it's been driving me nuts for years now as I've not had the physics skills to really answer it. But this Space Time episode seems to do it, or at least come really close. The physics (as explained in this episode) seems to point to conversation being possible because of the random qualities of quantum mechanics (regardless of Copenhagen vs many worlds). That randomness would eventually manifest itself into consciousness and cause a "split" in what each copy would want to say. Eventually (or maybe instantly) each copy would have made different "choices" as to what to say and a conversation could be had. And that seems to point to free will being real.

[@anon2497]

First, love that you did this episode - can be a risky subject, but should be addressed, and you addressed it pretty well, so kudos. Having said that, I have some quibbles, because... of course I do. ;) 1) I don't think the creation of NEW information is a requirement for agency, simply influencing the DIRECTION of information could represent a choice - or even just the ability to affect a probability distribution in a non-deterministic manner could demonstrate free will. If encountering a "Free Agent" (brain, or whatever) ALTERS the course of events in a manner that is not normally observed where no agent is involved, then that agent has made a free choice. They have taken a set of inputs and caused an atypical result. IE: They have acted on the information in a manner that demonstrates the ability to control, rather than be controlled by, the information. I don't think it's necessary to completely disconnect from a system to demonstrate free will, freedom to move WITHIN a constrained system is still freedom - and more importantly is the only presumption that makes any sense. The ability to create something from nothing is Godhood, not free agency... and a bit of an unreasonable ask in my opinion. ;) 2) On free will and randomness. I think this comparison is something of a problem. Since we generally define "random" as "unpredictable", free will MUST, to any outside observer, appear random. If an outside observer could perfectly predict the outcome from an encounter with the agent, then it can only be presumed that no CHOICES are being made by that agent, which doesn't necessarily mean the agent doesn't have free will, but only indicates they did not exercise it, or have already used it previously to "lock in" their future behavior, and aren't any longer exerting it) and thus free will in that encounter isn't even something that can be discussed. The observed outcome would be indistinguishable whether free will is present or not. The agent/event in question is simply acting as a transformation function and could be represented as a natural law (or perhaps a complex combination of laws, but same basic principle). Therefore, the question of free will can only ever even be ASKED when a non-predicted (ie random to the outside observer) outcome/event is observed. My personal postulate at this time is that the inherent non-deterministic nature of the micro universe demonstrates that free will is not only possible, but inherently present. The "apparent" deterministic "laws" we observe in the macro world (and the fact that they ONLY seem to apply at macro scales) are simply the results of emergent statistical principles like the "law of large numbers". That is to say, that the predictability of the macro world is not proof of a deterministic universe, only evidence that when you get enough free agents together that their GROUP BEHAVIOR becomes statistically VERY RELIABLY predictable. Basically, what I'm saying is that if I took a few billion people and handed them an egg crate and 12 colored eggs (each egg of a different color, but each person receiving the same 12 colors) and instruct each to put the eggs in the crate, the fact that the outcome is deterministic on the macro scale (I have 12 eggs in each crate) at the end doesn't demonstrate a lack of free will, only a set of restrictions on the range of choices available. Each person will likely fill their crate with a different color arrangement (micro scale). Again, from the final perspective the micro-world arrangements will appear random to an outside observer (the final result state no longer contains the information on how decisions were made, and therefore appears "random") and I can even make very reliably predictions about the overall arrangement patterns using the principles of statistics (like how many crates of a given color arrangement I can expect to see). Nevertheless, neither the predictability (or lack of randomness) of the end state, nor the failure to create a new/unpredictable outcome (like a crate with only 11 eggs in it) demonstrates a lack of free will. It only shows that we have lost the information involved in making those free choices by the time we see the results. In other words, I don't believe the existence of a deterministic macro universe precludes free choice, it only shows that those choices are constrained and reliably predictable on a macro scale, or that the information used in making the decision was lost or hidden... (not that I particularly subscribe to the idea of a perfectly deterministic universe as that has never been remotely proven except on HUGELY macro scales where individual "choices" would be so overwhelmed by statistical forces as to be no longer discernible from error margins anyways...)

I think people are very confused about what "free will" means, switching definitions of free will mid-argument sometimes. For example, someone might argue that you are only responsible for your actions if you have "free will". Then they will say that if the universe is deterministic, you do not have "free will". So in a deterministic universe, nobody is responsible for their actions, legally & morally speaking. However, the "free will" of a discussion around personal legal and moral responsibility is more about saying that you were not forced to do it, it wasn't an accident, and you were not suffering from some kind of mental issue that prevents you from making decisions as a human normally would. These are not really relevant to a discussion of a deterministic universe.

So it is all pre-determined (not that some other consciousness pre-determined it for us humans; it is just pre-determined by the nature of the laws of physics.) It is this way in our perspectives i.e. human brains cannot and will never ever evolve in a way to surpass this. Assuming there are higher dimensions (very high probability there is) we will always be limited to the 3 physical and 1 time dimensions because our brains and bodies are made in such a way it will not allow us to be aware or conscious of other dimensions.

I don't think such an assumptions is made. The intention is to highlight that we either "choose" the instance we are in, or that we are just randomly in the instance we're in. One indicates a level of free-will, the other indicates pre-determinism. Both are possible, and currently untestable, so we cannot determine that one is true and the other false.

[@eliomonaco147]

Exactly. There is also other thing that I think should be addressed. At 5:10 he gives the criteria by which he argues a brain could be reasonably considered free. Any combination of the first three criteria that he wants to use can be applied to simple computers. Just take a true random number generator (like hardware random generator using quantum events as a source) and boom you have a computer card with free will. In fact such computer takes in quantum information, processes it and spits out an answer that it is not predictable, neither in principle nor in practice. At the the host adds that the brain can also recursively influence itself via consciousness, but a recursive influence could be programmed into a machine easily as well. It certainly will not be an influence as complex as consciousness, but the end result would be the same: a machine that makes decisions which are unpredictable (both in principle and in practice) by incorporating both outside and inside information. Even though this is perfectly consistent with the parameters he laid out, I don't think most people would agree that true random number generators have free will. In other words, sure, the laws of physics leave room for free will for humans, but such free will is something that many other not living objects could posses. Connecting this to his statement at about 12:05: one can assign whatever meaning they "feel" to assign to something, but that does not make it objectively meaningful. I, as a human being, can assign a lot of meaning to the complex chemical reaction that I call love, while also accepting that it is no different from any chemical reaction I can make in a lab to which I do not assign meaning. In the same way, I can also assign importance and meaning to my complex decision making process while also accepting that it is essentially no different from that of a complex random number generator. My whole point here is that, the "free will" that meets the criteria laid out in the video may not be an illusion. The illusion would be the belief that such free will sets us apart from complex machines (none of which was stated in the video, but which is normally implied when discussing free will).

Personally, I like the idea of the many worlds interpretation meaning that either the future is undeterminable, or every possible future is determined, since it means that you do actually have choice. The latter option, I feel, is also ideal for religeous individuals who believe in an omniscient entity, as it allows for that, whilst also not destroying the notion of free will. Also, I think it doesn't entirely matter whether or not free will exists. If it does, then great! If it doesn't, then there's nothing we can really do about it, so there's no point in worrying about it - as far as we need to be concerned on a day to day basis, we make our own choices that have an impact on the world around us, and the only way believing that there is no free will can truly impact you is if you let it stop you from living your life.

"your" future doesn't seem determined only because you cannot know it.

According to Penrose, the human brain functions as a quantum computer, and since quantum information is eternal and cannot be destroyed, it must exist somewhere. Since we know the human body will eventually decay into dirt, (at least when not tampered with filled with chemicals, and sealed in an armored metal box), and we know that dirt does not contain all the quantum information of every computation our quantum computer brain ever made, then it must exist elsewhere. Process of elimination seems to leave one answer that doesnt take playing mental twister to justify, which is that we have some other, non physical, consciousness, where all those computations continue to exist, eternally, as we know quantum information must.

Great presentation, Matt. I personally find it very frustrating that so many of the people in recent times to attack the notion of free will either ignore quantum mechanics altogether (and just assume, unjustifiably, that physics is deterministic), or make some cavalier statements that attack your item 4 but leave the central question unaddressed. One thing where I think we can go further is the question of 'where' the information comes from. It's not obvious that the information has to come from the brain (or else the brain didn't meaningfully 'choose'). For all I know, all the fundamental uncertainty that I associate with my freedom to make choices is actually already embedded in the universe since its beginning, and my brain only makes use of it, its information processing shaping the distribution of possible outcomes. Our experience of our minds being localized to within our brains could just be an artifact of all our information processing happening in it -- but if all you want is something to make meaningful choices with, you don't need it to be localized, only to be able to access it in that localized space. Scott Aaronson lays out this idea in his essay "The Ghost in the Quantum Turing Machine", which everyone interested in this debate should read. Another intriguing possibility SA describes in the above is an earlier idea by Hoefer that we may not have the right boundary conditions for thinking about ourselves in the universe. He argues, sure, if you have a 'block universe' picture, free will doesn't seem to make sense, but neither does causation -- if everything just 'exists' it makes little sense to say A causes B, at most we can say B following A is consistent with whatever dynamical laws are in play. So, in that sense, you can just as well imagine that B caused A! The idea then is that these degrees of freedom in the beginning of the universe, which in the previous paragraph you could think were just a 'random number generator' for the brain, here are generated by your choices and carried back to the beginning of the universe by the usual Schrödinger equation. What we normally think of as 'causality' is emergent in this picture, but what's interesting is that, as long as you only think of your brain as effecting causation backwards when interacting with quantum bits that were undisturbed since the beginning of the universe, the usual thermodynamic arrow of time is respected and no backwards in time signaling is allowed. I'm not sure that's a fantastic solution (certainly seems arbitrary) but it's interesting to me that it seems consistent. All in all, I think it's great to see a more balanced debate on this. The 'science disproves free will' claim is as omnipresent as it is unjustified.

To my knowledge, nobody has been able to come up with a theory that produces clear predictions without this ingredient. The Everettian "many worlds" picture tries to dispense with it and explain observations as a consequence of decoherence, but decoherence alone often fails to cleanly identify a branching structure because a density matrix may be diagonal (or almost diagonal) in more than one basis. Proponents have been trying to square that particular circle for decades, without success. Some, such as Lev Vaidman, have managed to come up with a version of many worlds that works (at least as far as I can tell), but it took reintroducing free choices into the theory by explicitly introducing agents and their choices as an axiom (perhaps this pushes it closer to a "many minds" theory rather than merely "many worlds"). Could it be that what looks like a free choice in every working interpretation of quantum mechanics be merely an emergent consequence of an underlying 'mechanistic' substrate? Maybe, but the fact that nobody has been able to find one in the >100 years the theory has existed suggests that it's important not to be dismissive.

The uncertainty principle does not state that things are actually uncertain, just that we change the outcome of something by making the observation, said another way, by interacting with the thing we are observing.

[@toriknorth3324]

The Heisenberg uncertainty principle is actually just a statement about the observable properties of waves, and only applies to quantum mechanics because of its formulation in terms of probability waves. Quantum information is information about the probability waves and so it conserves the wave uncertainty as well. I think the uncertainty principle should be called the indeterminacy principle or something, because we are precisely certain about the limit to which we can determine paired properties of waves.

In other words, the fact that we experience life with a sort of lacuna toward the underlying physical processes that may be deterministic tautologically implies that there is a gap between this base physical reality and the way in which we experience reality, which is what I believe the term "free will" is supposed to evoke in its essence.

I think when most people talk about free will they're referring to their higher-order decisions, not "anything their brain decides". Most people would not call their heart beating an act of free will even though their brain is deciding to cause it to beat. Therefore, in order to prove free will it's not enough to show that any old brain region is doing things on purpose, but instead that your conscious decisions or thoughts are non-deterministic. From my understanding of physics, I don't see how it's *not* all deterministic. That is, even if we find that quantum processes are actually random, free will would require that we would be able to consciously and deliberately influence those quantum processes which is not possible. Bottom-up non-determinism is not free will, only top-down non-determinism is. And influencing quantum outcomes with the power of my thoughts is way too pseudosciency for me. I also disagree with #2 on your list. If a "choice" is deterministic (an oxymoron) it's not a choice, regardless of whether or not it can be predicted.

[@thstroyur]

"From my understanding of physics, I don't see how it's not all deterministic" That's simple: the consciousness that grounds said free-will isn't ultimately material, and therefore physics has nothing meaningful to say about it; but if this sounds "too pseudosciency" for you, note how you only presume the converse because of NCCs and untested assumptions...

[@the42nddragon]

First of all, determinism isn't about answering all possible questions, just the very specific question "what will the state be at time T"; Second, if I remember correctly, the halting problem requires a Turing machine with an infinite tape, which itself is physically impossible.

[@andemil3567]

@@the42nddragon I couldn't agree more: the Halting Problem is a special case of "what will the state be at time T", namely when the state is "the Turing machine has haltet". Since even this is not computable (under the Church-Turing thesis), there is no chance to determine all future events either. To your second point: if it is physically impossible to determine the future with an infinite tape (i.e., with an infinite amount of memory), then it is also impossible with a finite amount of memory. So again it means that a Laplacian demon cannot exist. I think this only supports my original statement that the strong Church-Turing thesis makes a Laplacian demon physically impossible even in principle.

[@cohomological46]

Yet another reason why Laplacian demon can't exist is because of chaotic nature of even classical systems (e. g. double pendulum).

[@jasonpatterson8091]

Three points countering much of your argument in this episode: 1. It doesn't matter in the slightest if we're actually able, even in principle, to predict a person's future choices. We can't precisely predict the outcome of virtually any sufficiently complicated system, including those with internal feedback loops (ex: the weather on Earth beyond the near future). That doesn't in any way make those systems nondeterministic, it just means they're complicated. 2. It doesn't matter if a person believes that they have free will or that they have that experience. Surely you wouldn't argue that simply because a person has had the personal experience of having connected to or spoken with God internally, that they have proven a deity or their ability to communicate with it in any kind of rigorous sense. 3. Emergent properties are deterministic - they are simply the result of the interaction of large numbers of particles in interesting ways. The redness of an apple has to do with the interaction of white light with anthocyanins in the apple's skin. The particular quantity, identity, and distribution of cellulose and fructose and water and some esters and alcohols are what gives a particular fruit its appleness. It's true that neither of those qualities is inherent in the individual atoms of the apple, but that doesn't mean that they aren't deterministic. If a brain cells start behaving in interesting ways when you dump enough in a bucket, that doesn't mean it's not deterministic. The only point you actually made in favor of free will is that it's possible for random quantum information to be generated in the brain and later for that information to be acted upon and/or incorporated into what will ultimately become some sort of action potential/choice. That's a pretty thin argument for the future behavior of a material machine being anything other than deterministic.

Do you have please some examples? I know a lot about merging of pop-culture version of quantum mechanics with spirituality in the west, but i have no idea how it looks in contemporary India. How widespread is it? Are there some prominent religious figures who talks about that, or is more like "foklore" stuff?

The argumentation in this video is as confusing as it is incoherent: Option 4, the only sensible option is thrown out from the start, and Option 1 is rightly rejected with the argument that randomness is the opposite of free will. The most revealing part is at 10:05, where involuntarily waking up in a branch of the multiverse is sold off as decision made by free will! By that standard we could argue that Schrödinger's cat "decided" to die. The whole argument finally rests on unpredictability, but no matter whether ennobled by complexity, chaotic behaviour or randomness, unpredictability does not constitute free will. That "any combination of the first three options" do not make a good candidate for defining free will, is evident when applied to the atmosphere: it is complex, chaotic, self-influencing and in general unpredictable, but can one say, that it is free willed in it's emerging properties? Can I say, it "decided" to blow my house over?

This!

Excellent deconstruction here. Thank you. I would add more generally that he is basically trying to say that feeling like you have free will (however that feeling is accrued) has to mean something so therefore free will is real. Why does that feeling have to "mean" anything or explain anything?

Freewell still seems pretty implausible to me
