This comes across as confused.
Every system is an emergent property. That's what a system is... it's all the parts + how they work together... that's the emergent bit, the organization... you cannot find that organization outside of the organization.
Mad Man P wrote:Where in the behavior of an atom would I find traffic laws?
I would be FORCED to assemble a whole host of atoms into systems and then create more systems from those systems a hundred times over before I had shot at accounting for human nature, much less traffic laws...
Because the behavior of atoms do not result in traffic laws... but the behavior of systems made of systems made of systems... do.

Any system is only collection of parts. The property of the system is of course related to how parts work together. How parts work together is however related to properties of parts. Therefore the property of the system is related to properties of parts.

You cannot have a system without the parts that make it up... but it is doing something that none of it's parts can do on their own... something NEW
Some of us call this new EMERGENT property, emergent property, unoriginal as that may be... you can call it whatever you like.

Carleas wrote:You can say that the way the parts interact is a fundamental property of the parts, but you end up saying that e.g. a molecule of clorine has properties like gas-when-isolated and solid-when-with-sodium. i.e., you end up just taking emergent properties and re-coding them as fundamental properties that aren't expressed until you get a system of parts.
Carleas wrote:I'd argue emergence is just a useful concept for thinking about phenomena that are easier to talk about at the system level than at the parts level. It's possible to describe traffic in terms of quarks, but it's so cumbersome that we're better off talking about it in terms of people and cars and traffic laws. In some sense emergent properties just don't exist, but a description of the world that makes use of emergent phenomena will be better than a description that tries to talk only about quarks.

I don't think "a system [] larger than the sum of parts" is straightforward.
Carleas wrote:If the parts have properties that can't be predicted* and are only expressed when arranged into a system, is that system larger than it's parts?
Carleas wrote:Take Conway's Game of Life as an example. The parts are completely defined by a few short rules, and those rules don't say anything about gliders or glider guns or blinkers etc. And yet we see those systems result from the simple parts, and we can say things about the larger systems that don't reference the parts explicitly and say something interesting and different about the system, e.g. the system will move across the grid.
There's no doubt where the behaviors come from, but at the same time those behaviors are definitely not properties of the parts (because the parts are fully and briefly defined in a few explicit rules). It's just semantic to say that the behaviors aren't emergent from the rules.
*"can't be predicted" is a bit loaded and I'm not sure exactly how true it is; they weren't predicted and seem surprising, and probably aren't predictable without running a simulation of the system to see how it behaves.

the saying is not "larger" but "greater than the sum of its parts" no one is claiming systems can violate the first law of thermodynamics but rather that they can provide better or even unique results.
As a simple analogy imagine an automated factory line that produces cars, if you were to keep all the parts, but disconnect them from each other, they would no longer produce cars.
I would think "able to produce cars" is a tangible property we could refer to as an emergent consequence of putting them together.
However you could take the term "greater" to mean valuing the number of quarks in existence or something silly and end up with "the quarks were merely arranged differently, no new quarks were created" but that would leave you blind to the difference between a car and a pile of junk... which is why no one adopts that untenable perspective and we all agree this qualifies as "greater" than the sum of its parts
bahman wrote:Could you describe the behavior of the factory in term of its parts? Sure. You can in fact describe the factory's behavior in term of a function. What I am arguing is that function exist. This is not the case when there is an emergence.
bahman wrote:Jakob wrote:Your argument stands except in one case; that of a fundamental property.
What is a fundamental property?
Jakob wrote:If this property arises AS being, in every being as its essence, then emergence is possible.
Well, let's accept that. By emergent we mean that the "being property" is not reducible to the properties of the parts. Now suppose that you remove a part. Suppose that the "being property" vanishes. This means that there exists a function which is 0 or 1 (not being or being) depending if the part is removed or not. This means that the "being property" is reducible to the properties of the parts since there is a function which explains the property of the system in term of properties of parts. No need to say that parts contribute in property of the system through their properties.

I could say "being".
I have more technical answers. But let's see if they are needed.

What if every part in order to be a discernible thing (namely, a discernible part) needs to share a fundamental property.

You don't seem to be working with the same definition of "emergence" as was intended.
Mad Man P wrote:An emergent property would be the assembly of a car... something none of the parts could manage on their own.
Presumably we agree on what happens at an automated factory and that none of the parts could assemble a car on their own, but when put together they can
You don't seem to think that qualifies as an emergent property, yet that's all I've ever understood anyone to mean by that term...
I'd be curious to hear what you think that term means if not that

Could you provide a hypothetical example of something which WOULD qualify as an emergent property?
bahman wrote:Jakob wrote:What if every part in order to be a discernible thing (namely, a discernible part) needs to share a fundamental property.
The properties of a part can only be known when they are naked. These properties cannot change. The part however seems to have different properties, charge for example can be screened, but that is only an effect due to existence of other things, virtual particles for example.
Jakob wrote:Namely a response-pattern to entropy. Some property that guarantees its resistance to being annihilated.
Only irreducible thing cannot be annihilated.
Jakob wrote:This is the case in hadrons.
Hadrons have charge and spin which are simply the sum of charge and spin of quarks within. I am not aware of another property.
Namely a response-pattern to entropy. Some property that guarantees its resistance to being annihilated.

And no thing is irreducible.

ah... so that's where you're going.
These arguments hinge on definitions... you can define consciousness in such a way that matter BY DEFINITION cannot account for it, but vacuous tautologies are a monumental waste of time.
I assume you're not trying to play a language game but instead you want to grapple with reality.

Carleas wrote:bahman wrote:[A system larger than the sum of parts] is what emergence is about.
That may be, but if it isn't clear what that means, then it isn't clear what would qualify as 'emergence'.
Carleas wrote:bahman wrote:[Conway's Game of Life is] predictable.
Note here that if the only way to 'predict' the outcome of an initial starting position is to iterate through the rules, that isn't predicting, that's just running out the game (to call that prediction is like saying that a game of football 'predicts' who will win by returning a winner at the end). A prediction function would be one that takes a matrix of cell values and a number of steps and spits out the end state without computing each intervening step.
Carleas wrote:One example of a prediction function is things like 'gliders', i.e. given a certain shape, we know that the shape will repeat in a regular way. 'moving' across the grid. The glider isn't based on the rules, the prediction isn't based on the rules, we predict the future state by appeal not to the individual cells, but by appeal to the arrangement of the cells. We observe some higher-order object in the space, and it lets us predict the future state of the game in a way that we can't if we restrict ourselves to descriptions in terms of the parts. That seems to satisfy the proffered definition of emergence.
Carleas wrote:And I think that's what's happening for consciousness too. We can describe human actions in terms of atoms, and qualia in terms of neural networks, but describing it in terms of subjective experience and thought lets us make reliable predictions by appeal to higher-order objects that aren't explicit in the 'rules' and aren't well predicted without reference to those higher-order objects.
