Is Reality a Controlled Hallucination? – with Anil Seth



The Royal Institution

How does our biology give rise to the experience of consciousness?
Anil’s new book “Being You” is available now: https://geni.us/anil

Anil Seth argues, using innovative combinations of theory and experiment, that our brains are prediction machines inventing our world and correcting our mistakes by the microsecond. Anil’s new perspective on consciousness has shed light on the nature of the self, free will, the intimate relationship between being alive and being aware – and the possibility of conscious machines.

Anil Seth is Professor of Cognitive and Computational Neuroscience at the University of Sussex, where he is also Co-Director of the Sackler Centre for Consciousness Science. He is also a Wellcome Trust Engagement Fellow, Co-Director of the Canadian Institute for Advanced Research (CIFAR) Program on Brain, Mind, and Consciousness, and Co-Director of the Leverhulme Doctoral Scholarship Programme: From Sensation and Perception to Awareness.

  1. At 1:04:00: ‘Ok, where is the newest restaurant in town? How are we going to carpool? If only the car industry knew as much about engineering a car door efficiently as much as we know about consciousness. Taaaaco Tuesdaaay!’

  2. What if we can create nanobots that build enviroments aand echochambers that create humans from sperms and effs and next step instructions for the to be human aliens on other planets. Then maybe in a few thousand years we can start communicate with radio signals and Elon Muska dream will come true maybe. To expand conciousness.

  3. The belief that YOU primarily are the body is contra productive when trying to understand consciousness or the bigger things outside our "Brain created" subjective reality.

    It is like a great consciousness are riding a doll sized bicycle, where the bicycle is all creation and life.

    The creator and the created are one and the same.

    The creation and the creator are one and the same.

    The created and the creation are one and the same.

    We are one with the creator, therefore we are the creator and one with all.

    Cheers 💌🤫

  4. READ…There is no such thing as consciousness. Its illusionary. Trust me. I am an exceptional thinker. It’s true. Another thing he doesn’t realize is that in this TRUE reality…without any actual real consciousness, it is a cold and dead world. In fact heat is only movement of particles. It’s not “hot”. That’s YOUR mind doing “hot”. You get it? No name of things. No actual language and no meaning….because meaning is just an illusion of the brain. In fact the brain is a “meaning” machine…and so…the real world really is just physics and particles and things….it’s not a “dog”, it is just a geometric shape of particles. In fact the whole universe becomes one object when you realize that it’s all just one pattern. All joined….even by the quantum vacuum…it’s all ONE object. There is no “life” or “death”. No “good” or “bad”….and when you are looking at the stars, you are just the eyes of the universe staring back on itself…..in fact, you are not even that….there is no such thing as an “eye”. Just particles in motion….noting more. Read again….this comment is the absolute final truth on the matter.

  5. " Change Blindness" Controlled perception.
    Consciousness is not amenable to examination using the 'scientific method' .
    Are there as many realties as there are conscious beings?
    The lecture is telling me more about how the brain works and not about the elusive phenomenon of consciousness. The "i" that is experiencing. Using the brain to access the environment.

  6. Interestingly I just had my 1st cataract op a few days ago so one eye focused differently from the other and I notice this affects how I see your optical illusions.

  7. My personal humble perspective about this, is that there is no real error computation happening in the brain during the process of learning, which is what the speaker mentioned and implied around minute 27 when talking about bayesian prediction and "how the brain tries to minimize the error between the out-in experiences and the in-out predictions/actions that we put into the world". His perspective is very much in line with the approach that artificial neural networks use nowadays, but the evidence that other scientists in the field have gotten shows this has nothing to do with the way that biological brains really work. There is no "ground truth" in the brain. We don't get a "true value we can compare our <<prediction>> to, as so to calculate an error rate and make the neurons adjust to minimize that error", cause if this was the case, how would the brain manage the different time scales for error compensation?

    In other words, there are things we experience in a very fast rate (like, for instance, temperature – if it's too hot the body needs to adjust to that and <<learn>> that it must sweat to reduce temperature, and that action needs to happen in the span of seconds), while other things have a much greater time scale (like learning how to master playing chess or the piano); so how would the neuron know when to expect that "ground-truth" from the real world to arrive, so it can compare it to its own prediction and calculate the error? From an architectural point of view (forgive my engineer side showing here) it seems absolutely implausible that 1) the neuron has any "knowledge" of how long it should "wait" until the signal it's receiving can be considered the "ground-truth" of a previous prediction made by itself and; 2) the neuron is able to uniquely and distinguishably store every prediction made in the past, so that they can be used once the theoretical "ground truth" arrives from the world in the future.

    Again, in my humble opinion, and not being by any means an expert in this field, it seems much more likely that neurons follow very simple rules that have zero connection with the predictions they are making, but instead they are simply just trying to "sync" their firing with the inputs they receive in order to maximize something much more mundane and trivial like the amount of energy or "food" they can get by doing so (that is, this implies there is a mechanism by which a neuron that successfully fires and triggers a chain of firing in neurons down the line is "fed" more than a neuron that is <<useless>> and doesn't provoke any firing down the line). Consciousness and memory, in this case, would arise from the structure of the synaptic connections themselves; although this is PURE PERSONAL SPECULATION. They would be nothing but emergent properties. Similar to the flock of birds the speaker showed in his presentation, neurons are simply trying to get "as much food as possible", and this is accomplished by synching themselves with the signals they receive from previous neurons. At a low level (neuron scale) this seems silly, but at a very high level with billions of connections to excitatory and inhibitory neurons, with forward and backwards loop connections, it's not implausible that this causes this simple rule could lead to complex behavior like pattern detection. These ideas are strongly linked to Varela's and Maturana's concept of autopoiesis, by the way.

    The connections between the neurons are the "highways" of the signals, and it's precisely that highway that **IS** our memory. That would also explain why we need to dream and/or think about events in our past, as by doing so we are "strengthening the highways", and thus "re-learning" the same thing over and over, by activating the same signals that event triggered in the past; and why this feels like we are "re-experiencing it" (and thus why remembering about that stressful situation in the past gives you a similar stress response, because you are literally activating the same neurons that <<take part>> into that reaction). Memory is just a mechanism for our brains to strengthen the connections between neurons for any given event that happened in the past. And from memory, I guess, *MAYBE* consciousness emerges.

  8. The reason you didn't notice things change in the image is because of slight of hand. Magicians do it all the time.
    Keep the person distracted and focused on something else while you pull the switcheroo.

  9. The self righteously delusional. Cause without it you would have an existential crisis…. Lol humans are a waste of space in this universe. Hopefully we go extinct soon.

  10. I do wonder what used to happen to me when I was 17/18. When I first closed my eyes to go to sleep, straight away I would see a bright light and I mean really bright and while that is happening I struggle to breathe and at the same time I feel like I am being pushed down on my shoulders but as soon as I fight to open my eyes all is fine apart from feeling a bit freaked out by the experience. It used to happen at least 3 times a week, but last time it happened was about 14 years ago. I was heavily addicted to ecstasy at the time so I thought it may of had something to do with that but I hadn't even had it the nights it used to happen. So really not sure what happened to me, would be nice to know.

  11. If you look down a flat street the horizon is higher. It's easy to detect the supernatural. It's actually obvious. It's intelligently designed to give you good vision. That can be only reason for it. Nobody pay attention to their environment.

  12. I think the recursive nature of human consciousness, which gives us the ability to reflect on our experience, gives human consciousness its unique character and power. Consciousness isn't a discrete function or thing or capacity. Rather, it is an organizational principle, an abstraction which we use to refer to the content of our entire sensory , emotional, intellectual proprioceptive, interoceptive experience, combined with memory and imagination. That's a lot of information at any given time, and we organize and prioritize it by regarding it as a single unified capacity or faculty; consciousness.

  13. It is but not necessarily … Is this scientific language? We should be talking about hypothesis or open question and than analysis is evidence…

  14. I don't understand why the idea of consciousness not being a product of our brains is called spiritual science. Do we call gravity spiritual? No we don't. Yet it's non observable. Of course we can experiment and observe matter reacting to it but we have only theories of how it works. Same as quantum entanglement and yet we cannot observe the bond between those molecules that can react to each other instantly no matter the distance they are appart. Why the subject of consciousness is any different? We accept in science some forces that are shaping our reality and why this idea about consciousness seems far fetched and call it spiritual. Can't wrap my head around it as for me it would be the most logical approach

  15. WTF is the "controlled" aspect. Control implies awareness, volition and effect. These do not exist in the misery monkey toolbox.

  16. Consciousness is the occam's razor for intelligence to outplace itself- otherwise we'd all still be 1 cell amoebas. It's evolution 101- a quantum superpositioning of our 5d/4d world where new thought displaces old thought known as Pauli quantum exclusion principle (a new thinking invention that now rules the world thru ai) precisely stating the displacement of one particular new theory will displace a previous one in some unique way usually- hence numerous string theories. etc.

  17. THANK YOU for describing these ideas without using the terms "incomprehensible" and "mysterious".
    The hype has gotten way out of hand.
    Such a refreshing presentation!
    I'm glad you brought up the concept of identity.
    That one is tricky. I'm pretty sure that identity is a complex illusion. I sure wish I knew people I could discuss these ideas with.

  18. I’m not intelligent or scientific but cannot help but believe that there is a consciousness and intelligence far superior that we all share and experience itself through us all, including all life. As we become more aware of it within ourselves in the stillness when our thoughts are quite. Like little ripples on the ocean and yet we do not understand we are part of the ocean. I mean no offence and only speak of my own experience. Love respect and peace to all.

  19. Yes. I agree. Our brain is a prediction machine. Our conscious mind can differentiate between racing at this prediction or not. It’s kinds of sad thinking how we are conditioned by our public school system to race towards it at a slave like speed. Conditioning is a powerful tool. Good and wrong.

  20. In every moment there are these quantum spheres within spheres with 6 different probabilities… we have free will with six probabilities in each moment of consciousness ❤❤❤❤❤❤❤❤❤❤
