Experiments demonstrating this won the Nobel Prize in physics last year. And its because the theory is computationally universal that I can get all of cognitive science and neural networks back out of it. Donald Hoffman: Reality is an Illusion - Reddit Heres a concrete example. Illusions like the Necker Cube, for instance, show that our minds can be tricked into perceiving things that arent there. 3. Get a daily email featuring the latest talk, plus a quick mix of trending content. Just like you have your own headache, you have your own moon. Thats an assumption that could be false, but thats the source of my communication, and thats the best we can do in terms of public physical objects and objective science. You can unsubscribe at any time with just one click. Looking at the cube, you can willfully cause it to flip between both orientations. This post first appeared on Knowing Neurons, [1] Hallucinations that result from alcohol withdrawal after excessive drinking. But if you look up at the stars, you'll notice that you'll see you see a mountain in the distance and then you see the moon and the stars coming up behind the mountain. Psychology Today 2023 Sussex Publishers, LLC. He is a professor in the Department of Cognitive Sciences at the University of California, Irvine, with joint appointments in the Department of Philosophy, the Department of Logic and Philosophy of Science, and the School of Computer Science. And why? As argued in Chapter 4 of the book, if the organism directly sees the concentration of oxygen, then it will probably move towards the highest concentration and die. With Isaac Newton they were fundamental and distinct. Arkani-Hamed, N., Trnka, J. Donald D. Hoffman | University of California, Irvine Hoffman, D. (2019). Full Pages. Do You Suffer From Pet Owner Guilt? ", Einstein and why the block universe is a mistake, With Hilary Lawson, Michela Massimi, Julian Barbour, Huw Price, /articles/donald-hoffman-spacetime-is-not-fundamental-auid-2281, Quantum mechanics and the return of free will. Een oog van de storm in ieder hemellichamen. To this end, Hoffman has developed and combined two theories: the "multimodal user interface" (MUI) theory of perception and "conscious realism". So if Bob follows Alice, but Alice doesnt follow Bob, and doesnt follow anyone else who eventually sees Bobs tweets, then they are not in the same communicating class. For instance, to measure the position of a subatomic particle with higher resolution, we must use radiation of smaller wavelength. And why? @danielhoffmanDC. So I wondered, could I provide a similarly simple formal foundation for the science of observation? What's the meaning of life? Britto, R., Cachazo, F., Feng, B., Witten, E. (2005). The snake I see is a description created by my sensory system to inform me of the fitness consequences of my actions. David Gross, a 2004 Nobel Laureate in physics, predicted in his tribute to Einstein that spacetime is doomed, that it is not fundamental. Objects beyond spacetime? Seated in your ride, you see a dashboard, steering wheel, and the road ahead. The New York Times - Breaking News, US News, World News and Videos The physics of spacetime must arise, precisely, as a special case of our new theory. I can take two minds, and they can generate a new, unified single mind. But my dad was a minister, and at church they were saying were not. Gavin Newsom . Stript er enkel de elektronen vanaf en verdeeld de rest via de polen weer over het stelsel. Donald D. Hoffman. If I see a train, I dont step in front of it. Here's a quick recap of today's developments: Former US president Donald Trump faces 37 counts in connection with keeping hundreds of classified documents in his possession after leaving the . Donald Hoffman - Google Scholar Donald Hoffman's The Case Against Reality is hard to get your head Hoffman uses the metaphor of a computer desktop and icons - the icons of a computer desktop provide a functional interface so that the user does not have to deal with the underlying programming and electronics in order to use the computer efficiently. A snake is an acceptable solution to the problem of telling me how to act in a situation. There'll be a number of dynamics of conscious agents that are compatible with it. But modern physics, from quantum field theory to gravity, now suggests spacetime is doomed. Donald J. Hoffman - Wikipedia And I'm saying that, no, all the stuff that we're seeing, it's a hallucination in the sense that it's just a visualization tool that doesn't resemble reality. And the less connections you have, the less fit you are. (2016) Grassmannian geometry of scattering amplitudes. But, not that much further. 380: 2015: And a really nice guy. Theres a metaphor thats only been available to us in the past 30 or 40 years, and thats the desktop interface. Big Think. Some relationships pose the choice to compromise oneself to sustain connection or to remain true to oneself. And thats enough to send truth to extinction. In certain string theories it might have as many as 11 dimensions. Any measurement of a 'distance' in this dimension (e.g., seconds, years, centuries) depends upon measurements of the other spatial dimensions - there is no direct method of measuring 'distance' in this dimension. A shuffle changes positions of cards. But in fact, they did address them. If you had to spend all that time figuring it out, the tiger would eat you. We could write this (12)(21). In reality, as you play the game youre toggling millions of voltages each second in an unseen supercomputer. . New York. Well, why not take the device out of the lab?

Cambridge, UK: Cambridge University Press. I was lucky enough to interview Hoffman and raise this objection to him; an abbreviated transcript of our conversation follows this book review. Right. Suppose you watch a video in which one race car clips another and spins out of control. This theory implies epiphysicalism, i.e., physical objects, such as quarks and brains and stars are constructed by conscious agents but such physical objects have no causal power. That doesnt mean that they dont represent something real out therejust as dragging a blue email icon to your trash really does delete an email file in your computer, stepping in front of a train really does kill you. 7. Whats more, he says, we have evolution itself to thank for this magnificent illusion, as it maximizes evolutionary fitness by driving truth to extinction. The Prosperity Consulting Group has 18 employees. And that simple formalism is the foundation for the science of computation. Hope is double-edged, false hope can set you on a collision course with despair. Many scientists and philosophers claim that it does. Still, we bank on the fact that our simulation is a reasonably decent one. Evolution shapes acceptable solutions, not optimal ones. Latest Releases The Crisis of Ageing Join the conversation Sign in to post comments or join now (only takes a moment) . The neuroscientists are saying, We dont need to invoke those kind of quantum processes, we dont need quantum wave functions collapsing inside neurons, we can just use classical physics to describe processes in the brain. Im emphasizing the larger lesson of quantum mechanics: Neurons, brains, space these are just symbols we use, theyre not real. So there are 62 x 61 x 2 x 1= 62!, or about 3 x 1085permutations, which is roughly the number of atoms in the observable universe. No intuition. Where did it come from? And thats pretty much all of reality, whatever reality might be. For instance, a shuffle of two cards might send the card in position 1 to position 2, and vice versa. The BCFW recursion relations hinted that there may be structures beyond spacetime. Company Website. Now suppose your fitness function is linear, so a little water gives you a little fitness, medium water gives you medium fitness, and lots of water gives you lots of fitness in that case, the organism that sees the truth about the water in the world can win, but only because the fitness function happens to align with the true structure in reality. Donald Trump described Pentagon plan of attack and shared classified Get Quanta Magazine delivered to your inbox, Get highlights of the most important news delivered to your email inbox. But we do it with mathematically precise models, and we start to address the big questions about why are we here and what is human consciousness about?

It's the utter failure to solve the hard problem of consciousness thats sort of forced my hand here. So, Occam's Razor fails to apply here because Occam's Razor is only about theories that can do the explanatory work. Similarly, objects that we perceive in time and space are metaphorical icons that act as our interface to the world and enable us to function as efficiently as possible without having to deal with the overwhelming amount of data underlying reality. Einstein tells us, in a famous equation, that energy and mass are the same. While panpsychism claims that rocks, mountains, the moon, etc. He quoted prominent physicists who agreed.[2]. This hint was pursued by a colleague of Witten at Princeton, Nima Arkani-Hamed, who with his graduate student Jaroslav Trnka discovered in 2013 a remarkable geometric object, the amplituhedron. [5] It is not an object in spacetime. An analogy may help. TED Conferences, LLC. Milton Keynes: Open University Press. In 2005, as physicists pronounced on the doom of spacetime, they caught a glimpse of something beyond. Donald Hoffman ( @donalddhoffman) received a PhD in computational psychology from MIT and is a Professor Emeritus of Cognitive Sciences at the University of California, Irvine. I was inspired in part by Alan Turing. Hoffman, D., Prakash, C. (2014). Generically, in the real world, that will never be the case. Janet Mulligan. If I glance in a mirror, I appear as a body, as one object among scores in space and time. The amplituhedron is a monolith beyond spacetime. So decorated permutations hint at a dynamics beyond spacetime, in which one communicating class, seen as the vacuum, morphs into several distinct communicating classes, seen as particles. But a dynamics of what? Gross, D. (2005). SUGGESTED VIEWING But evolution offers a metaphor: Spacetime is just a headset by which we interact with an unseen reality. Einstein and the search for unification. [7] They can also differ in spin, the directions in which tweets flow through the class. And then that will give us some insight into what's going on in the realm of conscious agents, what they're up to, and then when we project that back into our spacetime interface, we should get evolution by natural selection or hopefully a generalization that makes new predictions beyond evolution by natural selection. So it's an objective reality that's controlling the hallucination. Then they prophesied its demise. They are certain that its got to be classical properties of neural activity, which exist independent of any observers spiking rates, connection strengths at synapses, perhaps dynamical properties as well. [5] New book: The case against reality: Why evolution hid the truth from our eyes. Thats right, the mathematics opened up the red pill and handed it to me. I can talk to you about my headache and believe that I am communicating effectively with you, because youve had your own headaches. Who ordered that? He has remained on the faculty of UCI since then, with a sabbatical during the 1995-1996 academic year at the Zentrum fr Interdisziplinre Forschung of Bielefeld University.[4]. "This whole tell-it-like-it . | Donald Hoffman | The Case Against Reality - YouTube Consider, for instance, a social network such as the Twitterverse. Pull it back through the interface out to the realm of conscious agents. Professor Donald Hoffman - The Blog of Author Tim Ferriss Let's try to pull that back, do a reverse interface. We feel its curves as gravity and see its singularities as black holes. In the critical realist's view, primary qualities like height and weight represent actual qualities of reality, whereas secondary qualities don't. And I mean, I could have had ITP and just say, well, there's a more complicated physical universe. Why do physicists say that spacetime is doomed? As we go about our daily lives, we tend to assume that our perceptions sights, sounds, textures, tastes are an accurate portrayal of the real world. I think it has been. And if Im not, Id like to know, what is that special magic beyond the machine? And so, it's no surprise that the stars look about as far away as the mountain, because they're both at infinity given my caloric resources. Quantum theory tells us that as wavelengths shrink their energy grows. Latour, Bruno. That is to say, what we see is not merely the light that hits our retina, but a far more user-generated experience, if you will, based on predictions such as faces are always convex and never concave. In that particular example, we know faces in our environment nearly always curve outward, but the occasional exception may result in a powerful illusion. So whats going on? But I think it is utterly false. The total matter within our reach is finite. Markov chains and mixing times. In a 4D space it is r4, and in an n-dimensional space it is rn. I put that out there so people have something to shoot at. Not so, says Donald D. Hoffman, a professor of cognitive science at the University of California, Irvine. Donald Trump Jeff Hunt Former President Donald Trump gestures as he leaves after speaking during the North Carolina Republican Party Convention in Greensboro, N.C., Saturday, June 10, 2023. I have a space X of experiences, a space G of actions, and an algorithm D that lets me choose a new action given my experiences. You turn your headset to the right and see a red Ferrari. Donald Hoffman (@donalddhoffman) / Twitter The Object Of Objective Reality: Some Notes On Donald Hoffman An adaptive fiction. Consciousness is fundamental."[8][3]. A critique of Donald Hoffman's user interface theory of perception Psychonomic bulletin & review 22, 1480-1506, 2015. Right, you have no intuition for how far they are. So, for instance, the volume of the 100-dimensional cube with sides of length 2 is 2100, which is about 1030. I was aware of quantum theory in the 80s, so no doubt it influenced me. The Dr. Dean G. Hoffman Endowed Graduate Award has been established by Dr. Hoffman's family in his honor. Theyre interacting with these guides that are actually telling them relevant stuff thats important to them, and every time they go back on another trip, they pick up where they left off and are learning new stuff. A special thank you to Chetan Prakash and Robert Prentner for their comments on an earlier draft of the article. Auden, who noted that it marked "a new direction for nature poetry in the post . Donald Hoffman, PhD received his PhD from MIT, and joined the faculty of the University of California, Irvine in 1983, where he is a Professor Emeritus of Cognitive Sciences. These are all very classical notions under Newtonian physics, where time is absolute and objects exist absolutely. Gravity doesn't create energy, energy creates gravity. But when you do a split-brain operation, a complete transection of the corpus callosum, you get clear evidence of two separate consciousnesses. Dominic Hoffman Those particles and fields are icons in the MUIs of conscious agents but are not themselves fundamental denizens of the objective world. When Im having an experience, based on that experience I may want to change what Im doing. Because, they argue, it has no operational meaning below the Planck scale,roughly 10-33centimeters and 10-43seconds. But if Alice starts following Bob, or if she starts following someone who eventually sees Bobs tweets, then they are in a communicating class. So, in this analogy, the simple motion of a car projects to a complex mess of pixels. Live news, investigations, opinion, photos and video by the journalists of The New York Times from more than 150 countries around the world. By Donald Hoffman We must take a creative leap. Spacetime is not fundamental. And then you see this relationship between the number of social connections and fitness. Hoffman has said that some form of reality may exist, but may be completely different from the reality our brains model and perceive. Its conscious agents all the way down. Then just assume the galaxies are expanding in an already existing, static universe. [8] Again, no one knows. Topics that scientists have in many cases said we dont need to address. This talk was presented at an official TED conference. In a 3D Euclidean space, the volume of a cube with sides of length r is r3. What about hallucinations? In a provocative new book titled The Case Against Reality: Why Evolution Hid the Truth from Our Eyes, psychologist Donald Hoffman suggests that the answer is no. He received a Distinguished Scientific Award from the American Psychological Association for early career research, the Rustum Roy Award of the Chopra Foundation, and the Troland Research Award of the US National Academy of Sciences. With playful references to The Matrix (There is no spoon ), Hoffman argues that perceptions that are veridicalthat is, truthfully reflecting objective realityare less likely to help us survive and raise offspring than false perceptions. Never. argues that our perceptions have evolved to hide reality from us. With Albert Einstein, and his 1905 theory of special relativity, they are fundamental and united. Merchant Marine Mariners Medal. DONALD HOFFMAN: Right. I review the converging. Darwin informs us that our senses evolved to keep us alive until we raise kids. Who am I? List of Purple Heart Recipients - American War Library And that is, what is space from the point of view of the interface theory? The Tim Ferriss Show Transcripts: Professor Donald Hoffman The Case Not only are they ignoring the progress in fundamental physics, they are often explicit about it. If you focus just on the pixels you see a hot mess: millions of pixels changing color and brightness. Hoffman Mulligan, CPA's, LLP. 2013. Thats the key idea. My intuition was, there are conscious experiences. [9] Reality may not be made of space-time and physical objects. So the idea will be that evolution has shaped us with a very simplified interface that's been shaped mostly to report the stuff that's going to keep us alive. Now you're choosing among them. In Professor Hoffman's book, "The Case Against Reality", what we think of as the nature of our reality is simply our subjective reality or our current interface. But most of us, you know, were born realists. We care about your data, and we'd like to use cookies to give you a smooth browsing experience. 1 1 If we only perceive fitness payoffs, why can I see the Milky Way Galaxy under a dark sky at night? As a concrete example, consider an organism that can only survive in an environment with an intermediate concentration of some particular substance. The amplituhedron is a monolith beyond spacetime. And then I could go back and look at the quantum stuff and realize, well, there is a way of interpreting the quantum stuff that's compatible with the interface theory of perception. So, as I upgrade my lab to make my device more precise, its mass grows to the point where gravity again creates a black hole, destroying my lab and measurement. So evolution agrees with physics that spacetime is not fundamental. But there is an intriguing new hint: decorated permutations also capture the behavior of a particular class of dynamical systems, called Markov chains. Those are the only categories available to you, and yet none of them are true about the file itself or anything in the computer. The physics of spacetime must arise, precisely, as a special case of our new theory. [3] Through supposing that consciousness is fundamental, Hoffman provides a possible solution to the hard problem of consciousness, which wrestles with the notion of why we seem to have conscious immediate experiences, and how sentient beings could arise from seemingly non-sentient matter. Well stay 300 years behind in our physics.. Reviewed by Kaja Perina, A full interview with Donald Hoffman follows this book review. On the other hand, it could also be that we just have addled brains. News. Particles are in spacetime. He likes the idea that we construct what we see. DONALD HOFFMAN - Professor - University of California, Irvine - LinkedIn Before that slicing happened, it seemed there was a single unified consciousness. Daniel Hoffman (@danielhoffmanDC) / Twitter The distance from me to an apple, say, here like two meters away versus another apple, you know, 20 meters awaythat distance is coding the percentage of my caloric resources that I currently have that would be required to be expended to get the resources in the apple at two meters versus 20 meters. Get unlimited access to thousands of articles and videos. This is a really, really hard one to let go of. Hoffman is a faculty member at UC Irvine and a recipient of the Troland Award of the US National Academy of Sciences.
