I don't know how it's even possible, but this is like the best / most concise / straight-to-the-point presentation of David's ideas by himself ever on YT, at least in reference to his first book. 9 minutes worth more than 99,9% of all the web content. Thanks!

Knowledge, something you rarely find on Facebook. If ever! 😄

I love this, thanks.

David can say more in 8 minutes, than some people do in entire books

5:00. 'Knowledge is the kind of information that is the basis for doing things.' ....or not doing things.

Explanations that share no mathematics with the way our sensory input evolved to be parsed by the brain are not to be scoffed at just because we find them unintuitive at the moment. Deutsch champions a creative approach to science - think through the seemingly unthinkable and eventually there'll be a paradigm shift.

A wild extravaganza of thoughts. I like his enthusiasm though.

"...it's the meaning that keeps it in existence."

Knowledge = Understanding the (The Universes ) program's functions ... discovering information that's already there

"Other times are just special cases of other universes." I seem to remember that quote as a key insight from Deutsch's first book. He broke down the multiverse into a set of three-dimensional snapshots of physical reality ("foliations" in the words of some authors), and when we organize these snapshots using the laws of physics and causality, we place some as happening before or after others in the same universe, while we place others in parallel universes, etc., but this organization comes from the laws or principles we use to organize them rather than being something inherent to the snapshots. "Parallel universes don't have hidden serial numbers." This seems to contradict Einstein's view of spacetime being a fundamental reality -- a four-dimensional block that can be sliced in various ways. Since reading Deutsch over twenty years ago, iirc, I've had both of these concepts of spacetime or the multiverse in my mind at the same time. Then you have Anton Zeilinger and his book "Dance of the Photons" in which he argues that physical reality is just the information that describes it. It doesn't have any inherent physicalness beyond that, and information, in that sense isn't merely a map or abstract description of something real. Rather information *is* what's real. Then you have Donald Hoffman's idea that it's all a bunch of interacting conscious agents, which can be mathematically described, and which are more fundamental than physical things (atoms and particles in spacetime) and more fundamental than information, which is something that pertains to those conscious agents. So... Yeah, Deutsch kind of started me off on a path toward... Wherever I am now. I certainly don't have the hard "physicalist" conception of spacetime based on Einstein alone that I had when I was in high school and college.

Fascinating thinker

i have come to realize from learning all the theories and reality and the universe /the brain it all leads back to one word =LANGUAGE

I lost it after the interviewer said. ‘David…..’

Brilliant

Alex, it would have been nice for you to further explore Deutsch’s claim that quantum computing would further prove the existence of other universes. From reading what he’s written on the matter, he seems to see it as one of the more significant pieces of convincing evidence. His stance is that if a quantum computer were to solve a problem requiring more computational power than there were in the universe (i.e. requiring more bits than the universe itself is encoded in), then that would imply computational power “borrowed” from other universes. Basically, where did the extra compute power come from?

Nice. Very nice. The man with the alliterative name knows.

what is the relationship of knowledge / science to meaning?

another good one 👍

To ‘start with what we know’ and then ignore consciousness as a fundamental element in the understanding of the universe seems like an incredible oversight.

He's talking about different aspects of reality, not fundamentals of it. Quantum mechanics describes the behaviour of very small particles, it doesn't say anything about whether they are fundamental or not.

how are ideas and information instantiated in the brain?

You can't understand anything without awareness, consciousness,and direct experience

Isn't it just an understanding of matrices of a patterns, where you can compute them and produce knowledge for a particular reason (as theory of computation and emergence showed us in GPT4 and similar systems). They can in fact produce knowledge, extricate it and shows us the skeleton of the knowledge, build upon it, even tough "it" have no symbolic understanding and “cognitive/human skills”.

"knowledge: the kind of information that can do thing (or 'solve problems' as we would say at the human level). Adaptations are a form of knowledge. DNA is a form of knowledge." this guy can think more generally than me

the 'quantum' rate and our reference model don't seem very compatible 🤔

Fabric of Reality rules!!!

It was really good but I would have thought evolution could be under the computation layer but I can understand why when I think that a fractal needs a seed so I do kinda get it I think, I’m not fully sure yet

I think accidental discoveries and such things like that tells us that human purpose and benefit many times precedes conscious knowledge. It is as if knowledge comes to us rather than the other way around. We may be surrounded by knowledge that just comes to us by osmosis

Does information exist ohne our consciousness? Do we transform information to knowledge? Or do we translate it?

On this question, it's best to go back to Kant. A difficult start but the correct start.

If we accept that the universe is rapidly expanding in every direction, accelerating in its doing so, and we accept what Roger Penrose says about it eventually spreading out so far and thin that it exhausts the math of countable infinity, it will be as good as empty space and the preconditions for a big bang will suddenly be present again, then consider the following. As photons spread out to the very edges of the universe, making it super huge and devoid of anything, there might conceivably be a bunch of light and old information at the very edges of this ancient dead universe. When the new big bang happens in Roger Penrose’s cycle, everything expands from a central point-the black holes are the old dead universes. Their coronas are the old information spread to the edge. An entire universe is inside, but an empty one. Every blackhole is a previous universe, unmoving and unaffected by the expansion of the new universe around it.

How would we recognize the ultimate reality if it stared us in the face? What criteria would we apply to distinguish it from all the illusions that came before? If we can't answer that question, then reality is not a useful concept to pursue. What we actually do when chasing reality is to progressively get better at predicting our sense data. That's all we can do and as fundamental as it gets.

can DNA molecules be described by physics? how do DNA molecules differ from physics?

9 minutes I will never get back…however, some of the comments made me roflmao🤣

The 4 categories he mentions correspond to: Atom Cell Unit of body Unit of mind If anybody manages to accurately specify the particle physical composition of these four, then the holy grail of current science: TOE (GUT) is solved. The sequence could also be arranged in a far more appropriate, TANGIBLE manner as: Matter (physics) Plant (Botany) Animals (Zoology) Humans (social sciences) This clearly shows why TOE (GUT) described as unificatoon of QM and RELATIVITY would always remain a pipe dream because none of the two has any relevance whatsoever to the other 3 aspects of REALITY. The reality he explains is exhaustive, while what physics fancies with TOE (GUT) is a miniscule part of the fabric. A solution is only imaginable if we substitute Standard Model with assumption of existence of 3 different types (sequences) of matter (geo-, astro- and eco-) sustainable by each of the 3 entities (PLANTS, ANIMALS and HUMANS accordingly) , while they themselves are composed, delivered and suatained by the interactions inside the earth among the same 3 sequences of particles mentioned, thus establishing a correspondence between the functions of MIND ~ epistemology and the CORE of the earth ~ ontology. Mathematical model of these interactions inside the earth to compose, deliver and sustain them (PLANTS, ANIMALS and HUMANS) on its own surface would be THE TOE (= GUT). Thus the fabric of reality consists of just 3 intertwined strands ~ no more. Our task is to disentangle the 3 as 3 unique ranges of sizes of particles with internal differentiations of sizes within each range that account for all internal differences within each entity too. The reason for the current DISCONNECT among the 4 strands (he mentions) is the fact that all the INFORMATION we possess originate from the flesh of animals we eat, hence lack any relevance whatsoever to the interior of the earth ~ clearly visible in the attempt by physics to UNIFY all processes while totally ignoring the only process in the entire known universe that delivers and sustains 100% of all life in it, THE DEVELOPMENT OF, AND GROWTH ON, PLANTS. The latter 3 he mentions are, in fact, functions of the 3 unique strands in the first.

This video is about relative or conventional reality.

Is anyone else bothered by some, perhaps quite a few physicists, referring to this thing called emergence. He references this with respect to evolution. But at its heart it does not represent deep understanding. It simply defines something we don’t understand. But if you consider this to be one of the big four, but you do this by implication that we really don’t understand this and it is a problem when we keep trying to classify this as though we actually do understand it. A case in point, is it predictable that life should lead to complexity and that complexity lead to consciousness? Is it a matter that all species have consciousness or only one, two, or a few?

the mushroom cut adds 300 IQ points to each version of yourself across the whole multiverse

Reality is discrete 3d matrix consisting of small cubes and matter are discrete machines moving in it with constant speed ("speed of light") - one step per one tick.

1:38 David says "theory of knowledge" as important part, but it should read theory of wisdom I think, sorry haven't checked his book, but GPT4 has knowledge, which is computation and as a neural network has some kind of evolution - and emergent properties are spawning from this models as well..so..

If a human did get to a point of sometimes being a conscious observer without tools in a lab but through the means perception....would knowledge be able to be affected as a result of the collapse after it is observed

To be honest, I don't see how categorizing into four fundamental theories (quantum physics, the theory of evolution, the theory of computation, and the theory of knowledge), coming up with an extra framework will help in understanding the Truth. Similarly Pepper identifies four world hypotheses-formism, mechanism, contextualism, and organicism (later adding selectivism), where he says all are distinct and one can't be made of another (basically another framework). I'm yet to understand the significance of coming up with additional framework(!??), and prefer someone who simplifies from existing complexity without reductionlistic approach.

Everything a person knows is filtered through the senses of the human body. We cannot truly know anything outside of our own minds.

I don't think reality is ultimate but rather primordial. What we search for is a way for it it end well for us. But that's the search for the end of suffering and you don't need to understand everything in order to do that but simply seek to to no cause chaos. Maybe what he means by fundamental is the premise of logical thinking that is primordial reality. If that falls, reality falls. For example finding the Valley of the Kings for the dying and resurrected God religions or on the other side forging it.

Monday, April 10, 2023 11:58 AM Ultimate reality • Fundamental idea ○ Quantum physics § Language in which other theories are written like General Relativity § Deepest ○ Theory of evolution § Basic theory of emergent object § Principle of evolution ○ Theory of computation § Processes in nature that transcend material subject that it is embodied in § Idea is abstract entity § What is moving things here is "information" itself, not its "instantiations" § Theory of computation: how information is processed in the world § Adaptions in living things □ DNA □ Brain § Transformations permitted by laws of physics ○ Theory of knowledge § Strands of fabric of reality ○ Purpose = teleology = a meaning § Knowledge's meaning keeps it in existence § Knowledge is information § Embodied in physical system □ DNA represents the feature of species □ Books So it has some kind of use

There is a very old saying in Hinduism. "Sab moh maya hai" which basically states everything is imaginary.

Knowledge? Whose knowledge? It's you talking about 4 strands as fundamental. Therefore, "you" seems to be the underlying foundation for those 4 fundamental strands. Hence, there's a single strand to be realized and that's your own "consciousness".

CONSTRUCTOR THEORY IS FASCINATING.

What is the difference between reality, ultimate reality, ultra reality, meta reality, extraordinary super special mega reality, and dreams?

DD, 7:57 "People accept quantum theory, but they don't accept it's parallel universe implications." Question: if there are infinite parallel universes, doesn't that imply infinite knowledge? Doesn't this imply God? (since one meaning of god is infinite knowledge)

Whenever I see questions like this I know that the respondent doesn't actually know, so it seems pointless to ask.

Fond of mental, a game of the intellect? Is frequency fundamental? "If you want to find the secrets of the universe, think in terms of energy, frequency and vibrations" - Nikola Tesla. Experiment to safely alter personal energy, frequency/vibration : Sing *HU* . Search how to sing *HU* . A sonic tuning fork, go beyond theory; have experiences?

how can quantum theory describe gravity?

All this so intelligent people have their own ultimate reality....

Wow, I think I can finally accept that there's no stopping AI development.

Theory of computation seems illogical as it is proposes something that is independent. In a deterministic Universe, nothing can be independent.

how are fundamental theories related?

1) Truth is a proposition that corresponds to reality. 2) Truth is what you call the working hypothesizes that currently informs your worldview and is the basis for your actions. 3) Truth is the dogma of your Holy Book or ideology. Oops. I wrote this on the wrong David Deutsch video.

Who, or what is asking?

There can be no ultimate reality. Reality is necessarily relative ( concerning infinity). Change is fundamental. The rate of change ( frequency) gives energy. Accretion of energy, governed by constraints, gives structures. Structures change by energy transfer ( higher frequency to lower frequency and vice-versa. Structures are in constant flux. It is really about processes.

The ONE is ultimate reality

It sounds like Advait-Vedanta 🤔

Conscious observers are Real

The most fundamental thing is consciousness. Consciousness is the ultimate Reality. You're welcome.

God particles is ultimate reality, can see through consciousness observation, eventually thinking pattern limitations exceeded leads to present crisis.

Interesting as an approach, but all the seriousness of the thing falls apart with the Deutsch afirmation "quantum mechanics theory implies parallel Universes"... what?? There's even no real consensus on the wave function colapse interpretation and therefore this theory cant even explain really what matter is, and this implies parallel universes?? No more wine for that table... please.

Spiritual is the next or missing universe(s) and dimensions…its infinite

Eh?

Ultimate Reality is realizing the end of the earth. The resurrection and final Judgment.

But this is all founded on belief, not knowledge, so the discussion goes nowhere near reality, as best I can tell. One could make a similar argument from the idea of God, yet only one or neither provides a proper view of reality.

furst ..... the matrix has you! 💊

Ultimate reality is NOTHONG.

WE, are the Ultimate Reality, always Here and Now, We are Eternity, have always been, the Only Real Steady Point, in Exsistence, behind the Motion-Ocean, Stuff-side of Life, We have Never been seen, Live can't be seen, Only Known, No one have seen the Living behind the Being, We are Name-Less, in our Eternal Nature. Life can't be Created, Life is the Creator. We All refer to the Same I, through our individual Consciousness.

Ok.....up to 1:27 and he has actually said nothing.

*So-called 'reality' is a function of sentience* ----- For example: _Space has no shape or size_ because it is *infinite* ----- sentient Beings (for example, a human) _imagine_ its shape and size in their _minds_ ----- but, without this sentience, Space, would not exist at all. Edwin Hubble, in the 1920s, deduced the _relative_ acceleration of galaxies through the application of his ‘redshift theory’ ----- but he eventually *doubted* what redshift actually represented. The *Big Bang* name was coined by Sir Fred Hoyle, during a radio interview, as a term of _derision_ due to his rejection of the idea. Sentient Beings create _their own_ reality ... in their _mind_ ----- there is *no* _objective_ 'reality' ----- it is all a function of perception.

There has to be long form between you and Deutsch

Evolution?. Really?

'quantum physics' then is actually only metaphysics -- the level of convergence and correlations, how everything falls into unity for a perfect geometrical equation: scripture or cosmic psychology is (true) psychology denoting soul mind spirit; theology is a science and science is informed by theology and even directed; physics cannot be seperate from philosophy and ontology because this system is multilateral, as philosophy is about the core, the center. For a while I been thinking what they mean by quantum physics, and I know that some modern scientist guys and physicists make it known that they "don't do that stuff" because it's silly. Light = photon Nature = physics Ether = dark matter Metaphysics = quantum physics. A quick Google search says the difference is one comes from the side of philosophy( metaphysice) whereas the other from science(quantum physics). ^ This is such a deplorable opinion and is not truth, and im certain modern man will sell this notion. Did you ever hear of Pythagoras or even Aristotle, whom the platonists debated with for further endeavor. Aristotle is more of a materialist, however is very much important for questioning and testing the Spirit of such findings. Quantum physics is the modern science guys way of becoming familiar to Metaphysics, merely dipping their toes in testing the waters. Jump in already.

Eternal Life is the ultimate reality after this temporary fake world has been destroyed soon.

Why do so many intellectuals have bizarre hair styes?

DNA embodies data, not knowledge.

None of his four strands would exist, however, without mathematics. If quantum theory is the language that all other physics are expressed in, then mathematics is the language of quantum physics. Etc. He also left out another arguably fundamental and important aspect: moral reality. It's said that the world is made out of the Hebrew letters, which can be converted to numbers and therefore mathematics (e.g., gematria). From that perspective, if mathematics is fundamental, it would appear that the Torah and its laws are therefore also fundamental, embedded in reality, and perhaps similarly to math even precede reality as we know it. So it might not be a good idea to murder people, for example, or steal, or commit adultery, etc. not only for relative/social reasons, but because those actions violate the very nature of our reality. That would accord with the Buddhist notion of kamma (karma in sanskrit), also, the law of intentional actions (those which arise from volitional consciousness) and their results.

there is no ultimate reality on this side of the veil…just general relativity

Mr Robert, i was wondering, what's the true purpose of human reproduction?

Again just opinions without any evidence. These people don't have a clue about "ultimate reality".

Ridiculous. Information is not fundamental. There must be something to comprehend it...And that something is Mind or Consciousness. Consciousness is fundamental to reality.

Evolutionary mythology is just a world view and believe system. It has nothing to do with anything .lol

Surely, the most important feature of reality is that Jesus died.

I doubt if quantum physics can explain human beings!! Because we defy any type of explanation period for the simple reason we don't come even close to an explanation of the complexity of who and what we are or becoming!! Or why do we have the problems that we do have and can't even come close to solving these problems!! We have a very long and difficult time before we come close to answering even tho most simplest of these questions!! And that my friends is a PERIOD!!

I have found that LOF, "laws of form" by g spencer brown; is a very useful tool to understand reality with (consciousness is implicit in LOF). LOF can generate most if not all branches of mathematics. And without mathematics, physics would be useless. I also use surreal numbers to think with and generate infinity equations/relationships with them. They include all of the different types/levels of infinities in current set theory en.wikipedia.org/wiki/Surreal_number Dig deeper read, Conway's "On Numbers and Games"
