The neurons don't need to act in accord with the intention since the intention isn't directed at the neurons. — Pierre-Normand
If so, how does downward causation work? How do we get from the intention to raise one’s arm to neurons which act in accord with that intention?Our thoughts are not instructions for neurons at all. The intentional contents of our beliefs and intentions aren't directed at neurons.
Excusez moi? In order to be functional, to act how and when they need to act, transistors in computers do need software instructions.They're typically directed at objects and states of affairs in the world. Our neurons need not be told what to do anymore that transistors in computers need be told by the software what to do.
You forget about the role of software information, which is part of the global structure.The installed software is a global structural property of the suitably programmed computer. What it is that the transistors are performing -- qua logical operations -- is a function of the context within which they operate (i.e. how they're connected with one another and with the memory banks and input devices). Their merely physical behavior only is governed by the local conditions, and the laws of physics, regardless of the global structure of the computer.
You are mistaken. No computer can run programming language/source code directly, translation to machine code is always necessary, unless, of course, you start with machine code. However our deliberations, thoughts and intentions are anything but ‘machine code’. Behold the gap.The hardware must only be suitably structured in order to deal adequately with the software instruction; it need not have instructions translated to it. If the high level code needs to be compiled or interpreted before it is run it's only in cases where the hardware is general purpose and it's native instruction set isn't able to run the code directly.
Again, you are mistaken, it is exactly that.The task of the compiler (or interpreter), though, isn't to translate high level instructions in a language that it understands.
Such a level of understanding is not at issue here. What transistors need are clear instructions. Obviously they don’t need to 'understand' anything else, let alone their position in the scheme of things.The neurons need not understand what their individual roles is in the underlying causal chain anymore than transistors in a computer need understand anything about their electrical "inputs".
The translation problem — from deliberations and intentions to instructions for neurons — persists.To be clear, I am not saying that the hardware/software analogy furnished a good or unproblematic model for the body/mind relationship. The purpose of the analogy is quite limited. It is intended to convey how top-down causation can be understood to operate unproblematically ...
Is that not analogous to the claim that the chess program is the computer?
Software needs hardware to run on ...
The intention does not get translated into instructions for the neurons and needs not get so translated.
In my analogy, talk of intentions, beliefs, perceptions, actions, etc., already occurs at the functional "software" level.
Neurophysiology enables it rather in the way the hardware enables the software to run in the case of a computer.
So, likewise, the computer programmer can write instructions that directly govern the logical manipulation of significant symbols and not concern herself with the task of the compiler, interpreter, or hardware.
The programmer need not concern herself with the way in which the hardware enables her program to run.
The high level software causally directs and controls the steps in the computational task, while the hardware enables but doesn't direct the execution of the intended calculations or symbolic processes.
The abstract mind, instantiated on the computationally universal brain, decides to move an arm.
It does not know the mechanism of how this is performed, because it does not need to.
The mechanism involves layers of sub-conscious neuronal control systems ...
Because we don't believe in magic, there cannot be any other explanation ….
My point was that you are talking a monadic substance approach to consciousness - the usual outcome of reductionist simplicity.
And all that was by way of dealing with the original point - what we would really mean by "top down acting consciousness". To remind you, I was explaining how constraints depend on semiosis and that in fact our human interaction with the world has at least three distinct levels (and so at least three distinct levels in which those constraints are evolving).
If we are talking about the neural level, for example, then that means the top-downness is to do with attentional and intentional brain processes.
Autonomous, responsible, free personhood is a prerequisite to rationality.There appears to be a trend in modern philosophy to deny the reality of the "I", the "self", reducing the "I" to simply a part of the community in some anti-reductionist manner. This I believe is a mistake. It is a mistake because it belittles the separation which exists between you and I. The separation between us is very real and needs to be respected. Without having complete respect for this separation we have no hope of providing an adequate understanding of the nature of reality. — Metaphysician Undercover
Still unresponsive.But my position deals with your "I" on three Pragmatic levels - genetic, neural and linguistic. All three are explained semiotically as habits of regulation that are produced by more general contexts. — apokrisis
If there is no "I" who perceives and understands the facts of social science, then how can you be aware of the facts of social science? If there is no a consciousness of succession in one and the same conscious subject, how can you be aware of the fact that you continue to stick with the facts of science? Without the consciousness of succession, without the retention of the earlier states in the present state, no such conclusion could be arrived at.
Who sticks with the facts of social science?Heard it all before a million times. But I stick with the facts of social science. — apokrisis
A thought cannot exist without a thinker.Of course you can't doubt it ... given that you are in existence as a socially constructed self regulatory habit of thought. — apokrisis
What you are neglecting is that the "I" here is a socially constructed concept enabled by the learnt semiotic habit of speech. — apokrisis
In the final analysis, in is nit you pulling the strings. You are just responding … — apokrisis
So you do have freewill — apokrisis
So forget "consciousness" with all its antique Metaphysical connotations. — apokrisis
In this case, when I choose to raise my arm, I, as a macro-level whole, cause certain neural changes for which there are no sufficient subpersonal causes.
As a result, certain neural activities lead to patterns of muscle contractions and extensions, etc., in my body. So certain neural activities cause bodily motion when I choose to raise my arm, and these neural activities occur, in part, because I cause certain neural changes when I choose to raise my arm.
Thus, as a macro-level whole, in a certain state, I cause change in the motion of parts of my physical constitution—including my neural parts—that is not caused by any of my parts, including any of my neural parts.
So then—on an emergentist account—when, for example, an individual is voluntarily exercising working memory, and holding information in thought in order to complete a task, by doing so, as a macro-level whole, they are causing a change in the activity states of certain neurons in the prefrontal cortex.
Or when an individual is deliberating and progressing toward a decision, they, as a macro-level whole, are causing certain changes in neural activity throughout multiple regions of the brain, by deliberating, or thinking certain thoughts.
I did not ask how we are being programmed. Instead I asked how emergent consciousness commands/ programs neuronal behavior.This is how we are being "programmed", to get back to the computer analogy. — Pierre-Normand
Organisms strive to survive, under local constraints, since those who don't so strive die off and fail to reproduce. — Pierre-Normand
The person -- the human being -- is responsible. The "higher level" isn't a higher level of neurological activity. It's a functional level (see functionalism in the philosophy of mind) of mental organization that relates to the lower level of neurology rather in the way that the software level relates to the lower hardware level in the case of computers...
... I am rather looking for a final (intelligible/teleological) cause -- something like a goal or reason -- because of the form of the question and the formal nature of the event: Why did so and so intentionally do what she did. — Pierre-Normand
Attention acts top down by applying a state of selective constraint across the brain. … top down integrative constraints are how the brain works. — apokrisis
It is only when early replicators not only were passively selected by environment pressure according to fitness, but also began to strive to survive and replicate, that they could be considered alive. — Pierre-Normand
Yep. That was the point. Life has meaning because ... there is death as its contrast. So because of biosemiosis or a new symbolic level of action, an organism could become a survival machine. — apokrisis
No-one? Are you sure? Tell me, what is the universe floating in?No-one says the universe floats in nothing ... — apokrisis
You agree with my point.... let alone that this would be what gives it a shape. — apokrisis
I agree. “Real existing” is a crucial qualifier here, since if constraints have no ontology, how can they have causal powers? Consider a bucket filled with water. If we term the bucket a ‘constraint’, then indeed one can say that the bucket causes (or influences) the water to have a certain shape. But how does this apply to a universe floating in nothingness? Assuming that this universe has a certain shape, we cannot coherently say that ‘nothingness’ causes the shape of this universe, because nothingness cannot have causal power, cannot constrain anything. So unless we are talking about “real existing” constraints, like buckets, we cannot coherently talk about them as being causal actors.When we look at what the laws refer to as real existing "constraints", we can refer to those constraints as "causes".
But this is to use "cause" in the sense of an influence, something which affects activity. We can say that these constraints have an affect on specific activities, and in this sense they are causes. — Metaphysician Undercover
I agree with your clear analyses.This perspective assumes that the atom is the cause of the relationships which constitute it. From the premise that a cause is necessarily prior in time to the effect, this means that the atom must exist before the relationships which constitute it exist. To my mind, this is impossible, to say that a thing exists prior to the existence of its constituent parts. To resolve this, we could say that the idea of the atom exists prior to the constituent parts, as the "blueprints" for the atom, but then we are no longer referring to the atom itself, but a Neo-Platonic "Form" of the atom, which acts as the cause of existence of the atom. — Metaphysician Undercover
My claim (see this post) is that Apokrisis' emergence narrative ( see this post) is very similar to Dawkin's Weasel Program. His counter-argument, as I understand it, is that there is a fundamental difference because Dawkin's Weasel has an unexplained starting point and his emergence narrative has not (?).I think this is missing Apokrisis's point. — Pierre-Normand
I hold that naturalistic evolutionary theory is incoherent and I also hold that it does not describe a top-down and/or teleological cause.From the moment of abiogenesis onwards natural selection became a top-down (and teleological) causal process. — Pierre-Normand
The problem with your claim is that evolutionary theory can explain variety. Variety is explained by random mutations in the DNA.It is a central problem of evolutionary theory that evolution can only explain the reduction in variety. It can't explain the presence of that variety in the first place. — apokrisis
Your response:random mutations. — Querius
Here you are talking about ‘random mutations’ and asked: ‘how does natural selection also create them?’ ...So natural selection can certainly remove those. But how does natural selection also create them?
(It's a basic issue in evolutionary science.) — apokrisis
Your response:Selection obviously does not create variety. Variety is created by random mutations. — Querius
Why are you babbling about mutations? — apokrisis
My point about your weasel was that the letters already exist. So how did that situation develop? Recombination is one thing. But where did that alphabet come from? If you want to say it evolved, run me through the story. — apokrisis
So sayth the emergent self who is confused about the roles of mutation and selection in evolutionary theory.... the problem is that you don't understand the current science well enough ... — apokrisis
Selection obviously does not create variety. Variety is created by random mutations.how does natural selection also create them? — apokrisis
Basic indeed, and I wonder why I have to explain it.It's a basic issue in evolutionary science. — apokrisis
I do suppose that at some point your emergence narrative also gets passed the phase of nothingness.Your scrambled sentence already begins with the counterfactual definiteness of some set of letters ...
Irrelevant.… a conventional set of marks which I know how to read and thus can tell a gibberish sequence from one that has a reasonable interpretation.
Not an argument. You talk of ‘limitations’, how is that not comparable to constraints?And your citing of Dawkins and evolutionary constraints continues to underline that you are nowhere near the kind of holistic emergence I am talking about.
Random mutations.It is a central problem of evolutionary theory that evolution can only explain the reduction in variety. It can't explain the presence of that variety in the first place.
Existence begins not with nothing but instead an "everythingness" - a "state" of unbounded potential. And then limitations develop to produce definite somethingness. ...
Complexity and particularity arises as the general … becomes more constrained in specific ways. History locks in its own future by removing certain possibilities as things that could actually happen. And the future is then woven from what was thus left open as a possibility. — Apokrisis
This reminds me of the famous 1948 Copleston vs. Russell debate on the existence of God. At one point Russell counters Copleston's argument from contingency by saying:"It just is" is perhaps even more mysterious than "something else made it this way", but it tries to pretend to be anti-mysterious and obvious to escape any worrysome metaphysical issues that arise when people start thinking. — darthbarracuda
I should say that the universe is just there, and that's all.
An excellent argument in favor of the fundamental irreducible nature of laws, which, as far as I can see, no one has attempted to address.... a realist would say that a "law of nature" is a real tendency or habit that governs actual things and events, but is not reducible to them. If a law is merely a description, then there is no good reason to think that it would apply to future behavior, since different things and events are involved; yet we make successful predictions all the time, not just in science, but in everyday living. — Aletheist
However, if you are correct, it is the claim that there is not necessarily something at the bottom.It is not a claim that there is something at the bottom that we must not seek an explanation of. — Pierre-Normand
Bitbol's paper is titled "...without Foundations". … There need not be an ultimate level at the bottom, and strong emergence allows us to dispense with the need for one. Yes, in a sense, it's emergence all the way... But there need not be a bottom, fundamental, level. — Pierre-Normand
Correct me if I am wrong, but does the very concept of 'emergence' not imply a lower level of (more) fundamental laws? Emergent stuff emerge from fundamental stuff, right?What makes you think that some laws are fundamental and some aren't? — Pierre-Normand
I agree. Also every post on this forum is a cogent example of top-down causation. Question is, do we find such causation in inanimate nature.I would have thought 'the placebo effect' provides a cogent example of top-down causation. — Wayfarer
Sean Carroll in his book ‘The Big Picture: On the Origins of Life, Meaning, and the Universe Itself’, Dutton, 2016 writes:Hah. ... So they are an example of top-down causality ... So snowflakes are a good example of an effective solution - a global equilibrium balance that reshapes the very stuff out of which it is being formed. What you call "fundamental" is what has got fundamentally pwned. — apokrisis
<my emphasis>A standard example given by proponents of top-down causation is the formation of snowflakes. Snowflakes are made of water molecules interacting with other water molecules to form a crystalline structure. But there are many possible structures, determined by the initial seed from which the snowflake grows.
Therefore, it is claimed, the macroscopic shape of the snowflake is ‘acting downwards’ to determine the precise location of individual water molecules.
We should all resist the temptation to talk that way. Water molecules interact with other water molecules, and other molecules in the air, in precise ways that are determined by the rules of atomic physics. Those rules are unambiguous: you tell me what other molecules an individual water molecule is interacting with, and the rules will say precisely what will happen next. The relevant molecules may indeed be a large part of a crystalline structure, but that knowledge is of precisely zero import when studying the behaviour of the water molecule under consideration. The environment in which the molecule is imbedded is of course relevant, but there is no obstacle to describing the environment in terms of its own molecular structure. The individual molecule has no idea it’s part of a snowflake, and could not care less.
Yes, I got that. The point I was trying make is that I do not see how unregulated chaos can produce anything other than … unregulated chaos. ‘Symmetry’ implies repetitive patterns, which are, as I envision it, absent in chaos.The circle simply illustrates the basic principle that a symmetry is defined by differences not making a difference.
Such phenomena can only take place in a stable orderly lawful universe. If instead our starting point is utter unlawfulness/chaos, we would not know what to expect. Given unlawfulness, particles could pop out of existence for no reason at all. The collection of particles could turn into anti-matter and/or form a conglomerate. During observation the cosmological constant could shift followed by an instant implosion of the universe. And so forth. Thorough unlawfulness all the way down is completely unpredictable.Unlawfulness comes in once we start talking about symmetry in the sense of dynamical equilibrium states - or broken symmetries that can't get more broken and so ... become effective or emergent symmetries again.
And this is better illustrated by a gas of particles. At equilibrium, every particle is as likely going forward as going backward. So all action settles to a collective average.
What you are talking about are events and laws that result from more fundamental laws. I have no problem with that idea, as long as it not offered as an "explanation" of laws at the fundamental level.... The ground state becomes a new effective symmetry - the ball rolling around in the circle of the trough - which the world then reads off quantumly as a new degree of freedom or an actual particle.
I am talking about laws and their constituents.Are you talking about laws or constants? Or laws with different constants? That is, do you have a clear story on how they are the same or different kinds of things?
That would be a description of the law of gravity.There is a speculative mathematical description of how gravity behaves ....
Indeed. A description of a thing is not the thing itself.However, this description is not gravity.
From 'descriptions of the law of gravity are not the real thing’ it does not follow that there is no actual law of gravity.Gravity is something we feel and affects objects. There v is no law of gravity, there are just some tentative equations which may be useful for synchronizing clocks.
Useful mathematical equations are not actual laws of nature, but that simple fact does not tell us that there are no laws of nature.… we just have useful mathematical equations but certainly no laws.
