But the philosophical point about the inherent limitation of objectivity remains. — Wayfarer
It remains mostly just as a remark of an obvious observation on human perception, but it fails to lock down limitations as actual limitations of knowledge. We cannot see all wavelengths of light, but we know about them, we can simulate them, we use them both in measurements and in technology. Understanding reality doesn't require limitless perception, nor is it needed.
To pose that we must have
limitless perception in order to understand reality downplays our actual ability of abstract thinking.
And it also produces another question; would unlimited perception of reality actually produce perfect understanding or would it just scramble the ability to understand everything by the lack of defined perspectives? That without a specific perceptive perspective and clear categorization while able to do abstract reasoning that relates to those perspective, it may form better understanding than the unlimited. A being that, for instance, would see all wavelengths of light, may not comprehend light any better than us due to the absolute visual noise it would produce. In that scenario there wouldn't be any actual ability to see matter easily and, therefor, that being would of course see more than us in terms of photons, but it would see less than us due to photons interacting with matter drowning in the sea of the wavelengths we don't see.
So to pose that our limited perception is limiting us isn't a strong conclusion because we could also argue that our perception strikes the perfect balance of perceptive observation that makes reality able to be navigated and understood more easily while we further have the ability through abstract thinking, mathematical calculations and building external tools to extend our comprehension.
As an analogy, in art, there are clear examples in which an artist had unlimited means to make whatever they wanted, without any problems with funding, equipment or inspiration and yet they were only able to produce something that people felt became worse than when they were stuck with limitations. We cannot conclude perceptive limitations to be equal to an inability to fully understand reality, not when incorporating our other mental abilities and capacity for creating technology to extend our abilities, as well as realizing how limitations in perceptions can make understanding
cleaner. Absolute, limitless perception might just become an incomprehensible mess that renders a clear picture into white noise and "objective conclusions" lacking even more details. So when would a being be able to understand the universe fully? Because limitations in perception doesn't seem enough of a defining criteria based on this.
I recall a quote from a philosopher of science along the lines of facts being constructed like ships in bottles, carefully made to appear as if the bottle had been built around them. — Wayfarer
Carl Sagan? He emphasizes the idea that sometimes people construct their beliefs first and then selectively choose or interpret facts to support those beliefs. Which is why modern scientific methods are rigorously focused on bypassing such biases. The ship in bottle-analogy refers primarily towards those conducting pseudo-science, empathizing the need for rigorous critical thinking, evidence, and scientific principles. Which is what I'm standing by as well when I say that my philosophical speculations are extrapolated out of science, not out of a belief first that I'm then searching for evidence to support. I did not focus much on emergentism before many scientific fields started to form similar conclusion in their analysis of extreme complexity. While the concept of emergence has been around for long in philosophy, it's only recently, with progression in things like criticality, that it starts to lean into the most probable position. And as I've mentioned, if it turns out to be false due to new discoveries, then I will simply have to shift my perspective to something that's more probable. I will not, however, change my perspective into something that relies on belief alone and cause just because it feels good or present me a sense of emotional meaning.
If, by 'laws of reality' you mean 'natural law' or 'scientific law', are these themselves physical? I think that is questionable. The standard model of particle physics, for instance, comprises an intricate mathematical model, or set of mathematical hypotheses. But are mathematics part of the physical world that physics studies? This as you know is a contested question, so I'm not proposing it has a yes or no answer. Only that it is an open question, and furthermore, that it's not a scientific questio — Wayfarer
The laws of reality or physical laws are the mathematical principles that guide processes in physics. Mathematics are just our way of extrapolating an understanding of the unseen. The equations we have is a language for interpretation and extending such interpretation to prediction has proven to guide how we test physics, and in turn successfully proven physics to a point in which we can act upon and manipulate it, which is why we have most of the technology we have today.
So are they part of the physical world? Math on a board and in our head, no, they're just the lens for which we see these underlying rules of the physical world. But they correlate, and something like the fine structure constant; its mathematical calculation is extrapolated out of the phenomena we observe and through that we can measure its impact beyond our perception.
The standard model is what's proven, the hypotheses part is what we extend out from it, theories that tries to breach into a theory of everything. For instance quantum electrodynamics is one of the most accurate theories in all of physics. Even if we found out that it is something else or part of something else, the math of its function remains and exist as a physical phenomena. Science does not prove something "wrong" with new discoveries, they prove a new relation and perspective that put previous knowledge in new light and a new framework. It's a slowly forming knowledge, like a statue that's forming by water droplets, slowly coming into shape. It's not a finished statue that's demolished and rebuilt from scratch with new discoveries. And math is the reason why, because the answers in math cannot be changed, only understood better.
String and M-theory are one of those areas where the only reason why it keeps existing is because the math works. If proven wrong, the math will still stay and have to be incorporated into what is proving it wrong.
Furthermore physics itself has thrown the observer-independence of phenomena into question. That, of course, is behind the whole debate about the observer problem in physics, and the many contested interpretations of what quantum physics means. I know that is all a can of worms and am not proposing to debate it, other than to say that both the 'physicality' and 'mind-independence' of the so-called 'fundamental particles of physics' are called into question by it. — Wayfarer
The "observer" in quantum physics has to do with any interaction affecting the system. When you measure something you need to interact with the system somehow and that affects the system to define its collapsing outcome. This has been wrongfully interpreted as part of
human observation, leading to pseudo-science concepts like our
mind influencing the systems. But the act of influence is whatever we put into the system in order to get some answers out. A photon launched at what is measured, for the purpose of a detector to then visually see what's going on; will have that photon affecting the system being measured. It's not that our mind does anything, it's that we have to put something in to get information out and the only way for the system to keep a superposition is to not have any influence, which means it is in suspended and dislodged from reality until defined.
If Christoffer responds to this and tries to correct your misconceptions, do you consider it likely that you will be inclined to tell him that his response was too long?
If so, it would be considerate to say so now. — wonderer1
:lol: This is more accurate than any prediction in physics
Sorry, I thought you were referring to the post I responded to. We'll see. — Wayfarer
:lol:
You ask questions and write about complex physics; it's like asking how an airplane function expecting a short answer, but if my answer is "
it flies", that wouldn't be much of an answer really.
If the problem with explaining apparently emergent phenomena is just that you need a "lot more computational capabilities," then what you have is merely 'weak emergence,' and reduction still works. — Count Timothy von Icarus
That's why in my very first post in this thread I said this:
I would posit myself as a physicalist emergentist. What type is still up in the air since that's a realm depending on yet unproven scientific theories. — Christoffer
The question is still
if it is possible and I cannot conclude either. But weak emergence and reductionism are not the same. Reductionism heavily focuses on clear basic interactions of the parts and direct relations to the higher sum property, while weak emergence still focus on how the interactions create levels of changes that propagate up to an emergent phenomena. The difference is that reductionism draws clear lines from the actions of the parts towards the effect, while weak emergence is a "slowly mixing liquid" where all steps in its progression becomes further part of the final emergence. You could still, if possible, calculate the progression with enough computing power, but it will not show clear causal lines, but instead a trace of the progression of changing operations within the system over time from initiation to emergent outcome.
A striking feature of quantum mechanics is known as “quantum entanglement”. When two (or more) quantum particles or systems interact in certain ways and are then (even space-like) separated, their measurable features (e.g., position and momentum) will correlate in ways that cannot be accounted for in terms of “pure” quantum states of each particle or system separately.
Quantum entanglement is a misunderstood concept. It simply means that a particle set in a relationary superposition with another particle and those particles are separated and then one particles spin is measured will give you information on what the other particle has in its spin since they are in relation. It doesn't mean we can directly affect a particle over long distances as a form of "sent information", only that the superposition when measured gives us information about the other distant particle.
Your post seems to blend two ideas though. That our conceptual framework is fundementally lacking, and that we simply lack computational power adequate to "brute force," our way through these issues. I would just ask if these are the same position vis-á-vis emergence? — Count Timothy von Icarus
It's about acknowledging the missing parts. We don't know if we can calculate or not, because we don't have the computational power yet. When we do, this will be a testable part of physics. So we cannot conclude our knowledge-relation to emergence yet, even if we can see it happening. Much like how we can see both general relativity working as well as quantum mechanics, but not have a theory combining them at this time. I'll speculate that we might even find clues to such a bridging theory of everything within emergence theories, seen as they focus on the shifting relation between smaller chaos into larger deterministic systems.
The way collapsing wave-functions happen sure do resemble the emergence from high complexity, if that complexity comes from things like virtual particles. Or it may just be that the collapse is based on superpositions dancing between probabilities until they're settling in one or the other direction, similar to a drop of water between two other drops of water pulling on its tension and then randomly ends up in one or the other. Meaning, there may be a fundamental randomness of existence at the Planck scale, in which mathematical and universal constants define where the random existence and non-existence forms and in what way. And some of this randomness ends up in a condition where it locks into place by attaching and guiding the ones already locked in place, and which causally scales up to collapsing into such a locked position which defines moment to moment reality. A form of fundamental emergence that flows like a fluid with an increasing ability for causality through scale; from extreme randomness to slowly solidifying into more and more defined states at higher and higher scales. If that's the case, it might be that at the largest scales, scale levels of the entire universe, there's no emergence happening, forming a boundary where reality cannot progress further and that the only thing expanding our universe is the underlying emergence pushing reality larger, explaining both the increasing speed of the expansion and maybe even dark energy.
But that's just some pure speculation at the edge of my mind, so grains of salt required or course.
With the former view, I do think it's quite fair to ask if superveniance and thus "emergence" are even framed in the right terms, using the right categories. This is in line with process-based critiques of the entire problem, that it rests on bad assumptions baked into science that go back as far as Parmenides. The "lack of computational power," explanation seems like a different sort of explanation. — Count Timothy von Icarus
What are the right categories? These categories are just frameworks for further thought, accumulating the broad grouping of ideas in order to communicate better the position being discussed. I personally do not like the labeling and use of labels in philosophy because I think they limit thought down to people throwing balls with labels on them, defined, and for some, unmoving and unchanging concepts that when someone extends a label outside of its "comfort zone" people rebel and proclaim it not correct according to said label. Physicalist emergence is just a starting point for me.
It's probably why philosophical debates goes on for so long. Most people don't use the ideas of previous philosophy as a springboard, they simplify it down into labels and use them as hammers. I can find ideas in Wayfarer's idealism argument that I fundamentally agree with, but not with the conclusion, so does that make me a pseudo-idealist? No, it's only about following where the ideas lead based on rational thought and logic. Emergence as I'm talking about it, is referring to the underlying behavior of nature and our universe to assemble into further concepts that act with functions not possible to be defined by their parts, and further what that means and how it acts upon reality. So trying to purely define ideas based on how well they fit into categories is part of the limitations in Wayfarer's idealism argument that I agree with; that we cannot progress knowledge by only acting out of predetermined categorization. If emergence as I argue about it, produces new positions not able to be defined, then maybe a new category is needed to define it?
