Mindscape 295 | Solo: Emergence and Layers of Reality

[@captainzappbrannagan]

Sean, can you do an episode on where we are currently with the Transactional hypothesis from Wheeler & Feynman? Where the electrons must handshake to exchange photons, and one photon must travel to the past to make this happen? Thanks!

[@TheTimecake]

I think the "in principle" notion is misleading in this context. In the counterfactual of "well, if I had unlimited computing resources..." one can immediately cut that branch of the possibility tree out of consideration, because it is impossible for any entity to exist while not having bounds to its existence, i.e. existing without a Markov blanket is an oxymoron. As such, when one examines the tree of possibilities after those branches which are impossible have been cut away, one will find that there are no possibilities where the "principle" which allows for reductionism to be universally applicable (in contrast to locally applicable) actually holds. I understand that is is counterintuitive, but that may be because our intuitions often extend into domains which don't correspond to reality without realizing it. For reference, I think the recent work of Chris Fields with regards to the necessary failure of commutivity for the joint probability distribution of any finite existing system (including, arguably, reality itself) may be good food for thought.

[@Amethyst_Friend]

Why must every entity be bounded and what do you mean by bounds?

[@TheTimecake]

@Amethyst_Friend To be "bounded" is to have some part of reality over which your identity does not distribute. One can frame "bounds" in terms of Markov blankets if one wants to be technical. Any entity that exists must have a Markov blanket because without one, there is no distinction between what an entity is and what it is not. I'm going to go ahead and say that if there is no reference frame in which a so-called thing is distinct from what that thing is not, then that thing doesn't exist. Hopefully that's doesn't appear as too trivial of a claim.

[@cliffordbohm]

​@@TheTimecakewhat if something is only mostly isolated. Generally I'm a sort of thing with limited interaction with the world. My interface is large, what with mouth, ears, eyes, skin, etc, but my heart and brain are closed off from direct interaction with the rest of the world... But, that's only, most of the time, if someone hoes in for brain or heart surgery, well that puts a hole right in the ol'markov blanket, but somehow they keep on being who they are - an individual, identifiable from others.

[@TheTimecake]

@@cliffordbohm The Markov blanket is a statistical boundary. It isn't necessarily an impermeable physical boundary.

[@cliffordbohm]

@@TheTimecake sure, but my point was that we can think of the brain as being isolated from the world, where the rest of the body makes up the interface between the world and the brain. In this model the brain is only influenced directly by the body. This results in a view where i, my thought process, is contained or bounded. That's all i need to have a sense of being an entity. I don't need perfect isolation, just some degree of isolation.

[@bestest1234567]

@@vogarnerit’s the same methodology and propaganda globally. They can’t see the rise of the conservatives or right due to these over exaggerated comments trivialising serious issues like race and religion.

[@SirLucidThoughts]

They shouldn't be worried because half of the is election on the republicans side are democrats who switched parties to ditch the war mongers. That includes Trump himself. He was a Democrat as well, but he has been appointing democrats directly as well. It's going to be better, stop fear mongering and stop listening to radical liberal media. As we speak, war is raging and getting worse and spreading, hopefully, Trump gets in soon enough. These wars must end

You might apply some of this reasoning to the rational that some people use in developing string theory.

[@Stadtpark90]

25:12 distinction: emergence over time as an evolutionary concept has nothing to do with the question of the relation between a higher level description and a lower level description: the relation between two descriptions exists independent of the passing of time. 30:02 strong emergence comes in two branches / flavors: the lower level description being false vs just incomplete, but with wiggle room. 32:00 weak emergence considerations 34:01 How to go about it? As physicists: state transitions / mapping, but many-to-one („throwing away information“) 39:50 (information is discernible difference (Joscha Bach): of course the information that is preserved must be discernible from the macro level, else it would be noise - the moment you decide to keep higher resolution information to integrate into your higher level theory (of volcanoes), it becomes part of the emergent theory / its no longer part of the discarded „noise“ of the lower level. What’s not obvious about that?) 41:44 The setup is done. What can we do with it?

[@PrototypePrjs]

So emergence is modeled like the different layers of the OSI Model for network communication?

[@thephilosophicalagnostic2177]

I believe consciousness arises out of many many layers of organization. It doesn't jump up directly from physics.

[@thephilosophicalagnostic2177]

OBTW, "International order" is an oxymoron. Read any honestly written history book. You'll see what I mean.

Thanks Sean love this episode! I’m going to have to listen to this and map it out as I was driving and couldn’t free build in my thoughts as usual.

[@robadkerson]

Could it be the case that you could have predicted the emergent properties but you couldn't KNOW that you predicted them correctly for a given environment? Something related to incompleteness theorem or even touring completeness.

[@Savemysoul714]

So if I’m a superfluid and quantum chaos and can’t interact with the environment and I’m becoming a shape or stuck between 2d and sphere and lasers and black hole and I live in an apartment what do I do. How can I live here forever. I can’t transform into a monster in a suburban town with children. Please tell me what to do because soon I will not be able to even walk to the dumpster so go to landfill to rot with rest of decaying Matter. I need to know what to do because ormus made me hideous and I’m decaying. Please tell me what to do

[@steveurquell3031]

Hi Sean, dunno if you read these! But your talk about "compressible" and "incompressible" map reminded me a lot about Stephen Wolfram's ideas about "computational reducibility/irreducibility". It made me wonder if you have stumbled over similar ideas, or whether there is something more fundamental here -- yet known -- that I am unaware of.

[@Mablak200]

I’m fairly convinced of panpsychism; I would definitely go with the option that phenomenal properties are identical to certain fundamental entities or structures in physics. We should constrain the theory to be perfectly consistent with physics.

[@phobosmoon4643]

how does phase transition and power laws relate to emergence?

[@___x6097]

I super appreciate the endeavor at clarity and common vocabulary which this paper puts forward. I think it’s significant that the paper is all about higher and lower level theories, in regard to the level of their complexity. At some points a human being is referenced as an example of a higher level “theory.” In common language and in very specific detail, I don’t think a human being is going to be encapsulated within a theory, no matter how complex that theory is. In principle I of course agree that all levels are consistent with more fundamental theories in physics, but I think some applications of emergence and also some applications of the use of “upward and downward causation” will be used to reference “things” and not just “theories.” Just thinking out loud, but a fantastic video and paper, thank you for your work.

[@DamianReloaded]

Maybe photons are not carriers of energy but a byproduct of the transfer of information through an energy/information field that become apparent when observed but might not be detectable in the case of gravitational information.

[@SONALI-w2s]

Consciousness manifests at higher degrees in strongly emergent physical/condensed systems, that implies consciousness emerges as in the case of the emergent mind manifesting through the brain.

[@flymypg]

You seldom make me lol. But "attributing the 76er's performance to the initial state of the universe and the laws of physics" made me completely lose it. Diving through explanatory domains can be funny! Or is it that Type 2 Emergence is funny?

[@johnrowson2253]

Why no discussion about the mathematical problems of quantum gravity that imply there is something in accurate about the micro theories ? that gives emergence the possibility of replacing the micro theory, flipping the metaphysics ?

[@abc0to1]

The laws of physics could also be a form of emergence, since they are laws created by humans within the scope of what we can observe. Aliens with the ability to rationally predict the collapse of the wave function must have completely different physics.

[@sanojh08]

maybe this has been mentioned but can you do your future episodes with facecam. i noticed that i can follow thought much better if i see the people articulating them. especially complicated thoughts.

[@AYCOHOLLEMAN]

It's admittedly a bit sketchy, but I wonder whether the following reasoning might not be an argument for strong emergence. The universe computes outcomes (future states of the universe) using the laws of physics. These computations seem to encompass arithmetic. After all, the universe gave us calculators, and they can do arithmetic. Thus, following Goedel, there are outcomes (true statements) floating around in the universe that can nevertheless not be derived from earlier states of the universe. (And who knows, consciousness is such an outcome.)

[@vicp7124]

I’ve often thought about emergence and I think the “emergentists” drive themselves bonkers by ignoring the environment the phenomena are emerging into.

[@vicp7124]

@ A fundamental particle can exist anywhere in the universe. Complex molecules like RNA only evolve and exist under certain conditions.

[@thephilosophicalagnostic2177]

The environment plays many key roles in the emergence of complex systems, including humans.

[@brettriggins81]

Yay solo! Office work day again 🎉

[@foolbart]

Sean, isn't the existence of a particle accelerator proof of downward causation?

[@___x6097]

Yes, I think a key definition is whether you’re talking about an entire level of theory across the universe or talking about limited systems, like a particle accelerator determining a lower complexity system. Key distinction and I think both ways of talking about these things are valid. Causality happens in many different ways, according to which system you isolate and are talking about.

In classical mechanics a firmness to pi is assumed. In quantum mechanics it seem the universe dose a pi dance to keep a hole from appearing in many places, like on a sphere. But then I'm guessing with both fists.

[@PifflePrattle]

I was using emergence in my weird art almost 40 years ago, back when computers in the home were a novelty. At least the physical primitive ink jet prints that remain are provably old, old enough to carbon date. I couldn't explain to arty farties what they were about. And to be fair the process was more interesting than the result. Maybe they'll be valuable one day. The possibility only occurred to me when the NFT racket started. After all these days pigs frequently fly.😀

Antimater îs în oposition of phase to matter. Statistics can made conection between planck scale and microscopic scale of elementar particles. Theory of discret groups May play a role. Fotons implied only 4 microspaces conected by a mathematical low of interraction between them. There are 4 tipe of fotons în qed. Temporal, longitudinal, and 2 others. Charge îs some integral over cinetical moment of vortexes AT planck scale. În qed, charge operator îs like. Quantum waves are real, propagate on this space-time quanta. But another tipe of wave that by corespondence became normal waves.Fotons simplest structures, infinit velocity to enthengeled 2 space-time quanta, neutrino some more complex structure, mass depends on number of enthengeled space-time quanta and frecvencies of internal oscilation.Our mind is conected by resonance, from conception to this reality. To see past, must mentaly resonate to other reality so Time îs complex and discret.

[@ZootaAndrewMahera]

Depends on how we used the word force

[@Simmo87]

I think it's a bit of a semantic argument. Others here will probably have a more enlightening answer than I do.

[@danp8321]

It's a crude analogy but if a straight railway is deformed into a curve, then a train following that railway would experience a force as it navigated the curve.

[@RealQinnMalloryu4]

I have not watched to the point on this video yet that gravity is a force I thought also gravity is curvature of space and time

[@pinkfloydhomer]

If you put an accelerometer on a charged thing in an electromagnetic field, it will sense acceleration. If you put it on a mass falling freely in a gravitational field, it will sense no acceleration. If you glue scales to your feet and go into free fall, the weight will register zero. Not a force.

[@csours]

I strongly believe in weak heuristics.

[@mw-th9ov]

The phrase "in principle" is doing a lot of philosophical work in the claim that the core theory predicts the location of a hydro-carbon molecule in the gas tank of your neighbor's car given the initial conditions of the universe. To start the claim would have to include the prediction of the meanings of the description of the items in question as applied to the items...location of the items...their causal relation to all the other items and events...and so forth. But if so that would not be possible in principle under the computable definition of complexity you favor.

@@A_M_Bobb He didn't say the word "evil", he was just being judgemental. You know, the sort of thing scientists are supposed not to be. By being judgemental towards something, we imply that it is morally wrong. i.e., evil. Other than that, great talk.

[@btn237]

As far as I can tell, the remarks were about the people who just got voted in, who are undeniably not nice people. Trump has basically been running to keep himself out of prison, and has gone all in on the fascist playbook to help his cause. JD Vance, Elon Musk and whoever else all seemed happy to take that approach as well (Sean noted Vance’s “universities are the enemy” remark, for example). Surely it’s a moral duty to speak out against fascism wherever it makes an appearance. If not against that, then what?

[@GatorDunnAZ]

People who believe in, and vote for, policies that cause direct and measurable harm, can reasonably be described as immoral or even evil. Whether that’s the totality of their being or not, it does sort of eclipse any potentially positive traits or behaviors. And personally, I don’t think compromising with people who want to cause harm to me and my loved ones is a rational action on my part.

[@jach8047]

Sean, I'm still listening to you even though we disagree on Trump. I think its ok to have different opinions on this subject and still remain friends.

[@HORNGEN4]

I have friends who like Trump. They're religious, not deep thinkers, emotionally driven, and virtually no grasp on 20th century history, government, or economics. They're pro life but anti-social policy, which is mind blowing. In other words...they have no grasp of reality.
