What. if I may ask, is the sense in it? 

Hudjefa10

Do you mean to say "nothing is bigger than X" is nonsensical? We regularly encounter such expressions e.g. "nothing is greater than God".

2Jiro
That statement is not nonsensical, but "nothing" is not being compared as a quantity either.
Hudjefa10

So you mean to say ... supposing there are no dogs and 3 cats and n(x) returns the numerical value of x that what 0 < 3 means is n(dogs) < n(cats) i.e. n({ }) < n({cat 1, cat 2, cat 3})? There must be some quality (in this case quantity :puzzled:) on the basis of which a comparison (here quantitative) can be made.  

Do you also mean that we can't compare nothing to something, like I was doing above? Gracias. Non liquet, but gracias. 

Just a thought, but what if our ancestors had used an infinitesimal (sensu amplissimo) wherever they had to... (read more)

There is sometimes a quantity on the basis of which a comparison can be made. This quantity exists in 0 < 3. It doesn't in "nothing is bigger than X".

LW is huge and I've just joined (it's been less than a year). I didn't realize ... apologies. I will be mindful of what kinda questions I ask. Gracias

Si, it is absurd. I take that to mean some kind of error has been committed. On cursory examination, it seems I've made the blunder the Greeks were weary of: considering nothing to be something. Only something can be greater/less than something else. Yet in math we regularly encounter statements such as  or , etc. Aren't these instances of comparing something to nothing and deeming this a valid comparison? Am I not doing the same when I say nothing is greater than , which in math becomes 

2Jiro
No. "0 < 0.5 is a statement about the numerical value indicating nothing. "Nothing is greater than X" is a statement about the size of the set containing things greater than X. You are using "nothing" with two different meanings.

This is curious. The usual is atheism using psychology to discredit theism. Roles are being reversed here with trapped priors, the suggestion being some veritas are being obscured by kicking religion out of our system. I half-agree since I consider this demonstration non finito

As for philosophia perennis, I'd say it's a correlation is causation fallacy. It looks as though the evident convergence of religions on moral issues is not due to the mystical and unprovable elements therein but follows from common rational aspects present in most/all religio... (read more)

Hopefully, not talking out of my hat, but the difference between the final states of a double pendulum can be typed:  

  1. Somewhere in the middle of the pendulum's journey through space and time. I've seen this visually and true there's divergence. This divergence is based on measurement of the pendulum's position in space at a given time. So with initial state , the pendulum at time  was at position  while beginning with initial state the pendulum at time  was at position .  The allege

I have nothing against AI as a Jarvis/Friday-like assistant/advisor. A bad workman blames his tools (absit iniuria). Some us don't know how to use stuff properly. My reckoning suggests that I'm aware of only 5% of my smart phone's capabilities. Sometimes I get these random notifications full of interesting suggestions.

I don't know the exact values Lorenz used in his weather simulation, but Wikipedia says "so a value like 0.506127 printed as 0.506". If this were atmospheric pressure, we're talking about a millionth decimal place precision. I don't know what exerts 0.000001 Pa of pressure or to what such a teeny pressure matters.

4Jay
That's the point.  Nobody thought such tiny variations would matter.  The fact that they can matter, a lot, was the discovery that led to chaos theory.
Hudjefa10

Most kind of you to reply. I couldn't catch all that; I'm mathematically semiliterate. I was just wondering if the key idea "small differences" (in initial states) manifests at the output end (the weather forecast) too. I mean it's quite possible (given what I know, not much) that (say) an atmospheric pressure difference  of 0.01 Pa in the output could mean the difference between rain and shine. Given what you wrote I'm wrong, oui? If I were correct then the chaos resides in the weather, not the output (where the differences are as negligible as in th... (read more)

This is a neat question. I think the answer is no, and here's my attempt to describe why. The Lyapunov exponent measures the difference between the trajectories over time. If your system is the double pendulum, you need to be able to take two random states of the double pendulum and say how different they are. So it's not like you're measuring the speed, or the length, or something like that. And if you have this distance metric on the whole space of double-pendulum states, then you can't "take the log" of all the distances at the same time (I think because that would break the triangle inequality).
1Jay
Any physical system has a finite amount of mass and energy that limit its possible behaviors.  If you take the log of (one variable of) the system, its full range of behaviors will use fewer numbers, but that's all that will happen.  For example, the wind is usually between 0.001 m/s (quite still) and 100 m/s (unprecedented hurricane).  If you take the base-10 log, it's usually between -3 and 2.  A change of 2 can mean a change from .001 to .1 m/s (quite still to barely noticeable breeze) or a change from 1 m/s to 100 m/s (modest breeze to everything's gone).  For lots of common phenomena, log scales are too imprecise to be useful. Chaotic systems can't be predicted in detail, but physics and common sense still apply.  Chaotic weather is just ordinary weather.

Would I be correct to say that chaos as a science lives in the margins of error of existing measuring instruments. For weather, we could have one input, atmospheric pressure, say 760 +/- 0.05 mm Hg (margin of error stated). So the actual pressure is between 759.95 and 760.05 mm Hg and this range just happens to be the "small difference(s) in initial value" that leads to prediction divergence. That is the weather forecast could be as opposite as bright, sunny and heavy rain, stormy depending on whether you input 759.95 instead of 760 or 760.05 instead of 76... (read more)

I think I see what you're getting at here, but no, "chaotic" is a mathematical property that systems (of equations) either have or don't have. The idea behind sensitive dependence on initial conditions is that any difference, no matter how small, will eventually lead to diverging trajectories. Since it will happen for arbitrarily small differences, it will definitely happen for whatever difference exists within our ability to make measurements. But the more precisely you measure, the longer it will take for the trajectories to diverge (which is what faul_sname is referring to).
7faul_sname
The margins of error of existing measuring instruments will tell you how long you can expect your simulation to resemble reality, but an exponential decrease in measurement error will only buy you a linear increase in how long that simulation is good for. If you don't like descriptive stuff like "sunny" or "thunderstorm" you could use metrics like "watts per square meter of sunlight at surface level" or "atmospheric pressure" or "rainfall rate". You will still observe a divergence in behavior between models with arbitrarily small differences in initial state (and between your model and the behavior of the real world).

Experiences differ. The experts I've seen bow out when discourse shifts, as it usually does in a free discussion, from one topic (they know like the back of their hand) to another (they have little to no clue about). 

Hudjefa-10

I didn't realize it was AI age until I did. I believe the Turing Test has 2 tiers:   

  1. A candidate computer (soft + hard ware) must perfectly mimic AGI
  2. An AGI must perfectly mimic a human

ChatGPT et all are probably past checkpoint 1

Hudjefa50

Bowdlerized version follows:

  1. Don't utter falsehoods
  2. Senses aren't reliable
  3. Don't comment on matters outside your area of expertise
  4. Please state beforehand that what you're saying is opinion, not fact
  5. Try to work with others to discover the truth
  6. Beware of confirmation bias and don't cherry-pick your "evidence" to support your pet theory/hypothesis
  7. All arguments boil down to a modus ponens, you better know how it works
  8. Allow people to recalibrate based on new information/evidence
  9. Moving to a more-easily defendable position when attacked for holding a stronger view i

Your 3. seems to have lost a lot in "translation." I read the original to mean something completely different: whenever you comment on anything, do not pretend to know more than you actually do. In my experience, those considered experts in any field are the ones most likely to exaggerate their knowledge and confidence, and I reason that's because they're strongly incentivized to do so. Also, why Bowdlerize this when you can just point back to the version this was vulgarized from? Basics of Rationalist Discourse

That's ok, different folks, different strokes. Yet, in the world in which this paradox lives, it is a mystery how we went/progressed from an absolute unknonw unknown state to where we are now, knowns, known knowns, known unknowns, oui? Do you have a hypothesis as to how this happened?

Hudjefa10

That's a very interesting train of thought. Would you like to expand on that a bit? Please read my reply to @localdeity (vide supra). How did we make that saltus from literally everything being an unknown unknown to (some) known knowns?

3Dagon
My preferred frame is different from that - no strict categories of known unknown unknown knowns or however many epicycles they're up to.  Not even a requirement that "truth" have any objective meaning (though there seems to be a consistency in my experiences that makes it a convenient model for most predictions). You don't know anything.  You have a lot of models of things, which are all wrong in various ways, but still useful for many predictions.  You can update the models and the weights within those models as you make observations, which makes them "less wrong", as the saying goes.  For humans, it's probably not even asymtotic in predictive ability, it's just overfitting to more recent history.  
Hudjefa10

Gracias, that's the exactly the point in me humble opinion. The origin (0, 0) for all knowledge is late Donald Rumsfelds' unknown unknowns. That means we made what could only be described as a quantum leap in epistemology. Raises the question do we know anything we didn't know already

Hudjefa1-2

I was wondering if the paradox was solved. The Wikipage doesn't inform much about its status in current philosophical discourse. 

The solution seems a sine qua non, before we can make progress.

Hudjefa10

Si, I have the same difficulty. However, sources indicate that Socrates/Plato/others didn't brush it aside as inconsequential. 

I tried googling, but haven't found anything that could be considered a solution.

Hudjefa10

I don't know what to believe. On the one hand we have people who are genuine about their concerns about a looming AI takeover and on the other we have those who think the current cohort of purported AI (ChatGPT et al) are simply sexed up predictive text apps.

Would I be wrong to say that AI is just an upgraded flint axe ... only a tool that grew a brain, well sort of?

He's what I would call a living puzzle. From my first encounters with late Daniel Clement Dennett III till his passing, I've always felt he needed to be put together like a jigsaw; perhaps that says more about the randomness of our bumpings-into-each other on the network than anything else.

He said of himself that he was an autodidact, which is wonderful news for those with a tanha (craving) for knowledge.

His deep (?) interest in memes as some kinda theoretical framework for the ideaverse has merit, his work though is non finito. If Dawkins is god (of memes), Dennett was for certain the high priest.

To sum up, the fecundity of this tree was limited only by its death.

Si, it's standing-ovation stuff. What I find odd is that the lyrics are human. I suppose, less out of necessity, but more out of possibility. If one were to classify the AI music, which bucket (Euro/Afro/Asio) would it fall into? I wonder ... a mashup perhaps? If this ain't your style, maybe something else is ... and so ... bucket.

As far as I'm concerned, you're one of few who show an interest in what could be loosely termed as a epistemological map. I've met a few netizens with the same intention although most of them were interested in the organogram of a single, specific discipline like mathematics.  

Your synopsis of how your system is constructed bears the hallmark of well-intentioned, dedicated effort. You get a gold star for that, everyone should agree.

His magnum opus was definitely his extensive work on cognitive biases, though his Nobel was in economics.
