John Searle's China Room


Quote by MF
Can you or anyone else propose another test? I'm quite open to the idea of any other kind of test.
Yes: figure out how the brain produces consciousness physically, and see if the AI has the right kind of physics to produce consciousness.

What you suggest (with respect) is not a test, let alone a test of understanding. What you suggest is an explanation (of consciousness, not of understanding per se).
It is a test based on an explanation; I am saying we have to solve the hard
problem first, before we can have a genuine test.

I am saying "the operator" means "the man in the room".



if the man internalises the rulebook, the man's consciousness then performs the role of the operator ("using" the rulebook), but it does not follow that the man's consciousness possesses understanding. The consciousness in this case is following a lot of (to it) meaningless rules, because the understanding is in the internalised rulebook, not in the consciousness.
...and supposing consciousness requires understanding; then the operator does consciously understand Chinese, because he understands Chineseby virtue of manipulating the rules; and the operator doesn't understand Chinese, becuase he has no conscious awareness of understanding Chinese.
This does not follow. Why should the man’s consciousness necessarily understand anything of what it is manipulating in the internalised rulebook (any more than the man in the CR understands anything of Chinese – the man in this case is consciously aware of manipulating chinese characters, but he has no understanding of them)?
If manipulating symbols is all there is to understanding, and if consciousness
is part of understanding, then there should be a conscious awareness of
Chinese in the room (or in Searle's head, in the internalised case).

But, by the original hypothesis, there isn't.

You could claim that consciousness is not necessarly part of machine understanding;
but that would be an admission that the CR's understanding is half-baked
compared to human understanding...unless you claim that huamn understanding
has nothing to do with consciousness either.

But consciousness is a defintional quality of understanding, just as being
umarried is being a defintional quality of being a bachelor.



there is a difference between competencies that are displayed
instinctively, or learnt by rote, and those that are understood.
None of the above shows that understanding requires consciousness, only that there is more to understanding than simply being able to repeat a few phrases.
If you understand something , you can report that you know it, explain how you
know it. etc. That higher-level knowing-how-you-know is consciousness by
definition.


The CR would, by definition, be able to process (understand) all concepts that impact in any way on an understanding of Chinese. What else is there to “understanding Chinese”?
Consciousness.
Is this merely your opinion, or can you provide any evidence that this is necessarily the case?
It is a matter of definition -- it is part of how we distinguish understanding
from mere know-how.

What is missing (in your opinion)? Oh yes, consciousness. But I don’t see why consciousness is required.

Write down a definition of "red" that a blind person would understand.

It is perfectly reasonable to suggest that anyone needs normal vision in order to fully understand colour terms in any language.

Would you deny a blind person’s ability to understand Chinese?
Or a deaf person’s?
They don't fully lack it, they don't fully have it. But remember that a
computer is much more restricted.

It has nothing to do with the information-processing sense of understanding what red is, it has only to do with the sense-experience of red.
If the "information processing" sense falls short of full human understanding,
and I maintain it does, the arguemnt for strong AI founders and Searle makes
his case. Remember , he is not attacking weak AI, the idea that computers
can come up with some half-baked approxiamtion to human understanding.




Where have I conceded that? But you seem to be implying that a blind person’s understanding would be half-baked.
Yes.

I dispute they are a necessary condition. If you place me in a state of sensory-deprivation does it follow that I will lose all understanding? No.
They are necessary to learn the meaning of sensory language ITFP. Once learnt,
they are no longer necessary -- people who become blind in adulthood
do not learnt the meanings of colour-words.

Are you suggesting that a blind person does not have full human semantics?
Yes -- neither does someone who has never been in love, given birth, tasted caviare and so on.
Of course they may have "good enough" semantics -- hardly anyone has full
semantics. But a silicon computer would be much more semantically limited than
a person.

Does this mean a blind person is incapable of understanding?
Not on the "good enough" basis. But the case of a computer, or chinese room,
is much more extreme.


Sensation is a necessary ingredient of understanding? Therefore if you place me in a state of sensory-deprivation it follows that I will lose all understanding, is that correct?
No: if you lack the requisite sense, you cannot attach meaning to sensory
language ITFP. If you disagree, define "red" in such a way that a person
blind from birth could understand it.

I think you are talking of a special kind of understanding here, one with high empathy. But I do not need to empathise with a Frenchman in order to understand the French language.MF
"High empathy"? Please explain. Is there such thing as a "low empathy"?

As far as I know, empathy is empathy. It is an ability to understand the curcumstances influencing another human being as well as the ability to identify with objects and animals other than humans. It is a part of understanding and a powerful by-product of consciousness.

You don't need to empathize with a Frankophone to understand the french language???

Of course you do. Otherwise you wouldn't be learning french. As soon as the vowels and all those damn silent letters start forming in your mouth...... and you have to twist an accent out of your tongue.... you are on the path to empathizing with the French people.... like it or not. You are assuming their role and method of communication. When you assume the role or.... "walk in their shoes" (so to speak) you are truely standing under them.... or.... understanding the people and their language.

Understanding describes a function in humans that is more complex than the simple ability to repeat words in a correct sequence so that communication in french or math or medicine is achieved. That is called comprehension and it is properly used by the Italians when they ask you if you "comprende?" as in "can you comprehend what I am saying?"

There is a reason there are different words to describe different functions... the differences between the meanings of words are slight.... but they are there for a reason. Terminologies offer subtle shades that help to distinguish the speaker's or writer's references and descriptions.

That is why you see cell differenciation in the plant and animal kingdoms. Different cells function in different ways. They don't work in other organs or tissues. They must be used in the context they have evolved to serve. Much in the way languages develope specific terminology to describe specific functions.

The alien term for understanding is different from the North American term "understanding". The alien terms describes a completely different function... they may use telepathy... they may have greater experiences they may hook up with parallel dimensions to ascertain the function of "ravlinz". For humans, and I'm not sure yet what the components of understanding are.... but for humans we use experience, consciousness, empathy and knowledge in a slap-dash mixture that we call "understanding".

Thanks!

I would argue that there are degrees of empathy. One person can show "more empathy" than another. Or do you believe that empathy is an "all or nothing affair"? Do you believe that it is simply black and white, either one has complete empathy, or one has none at all?
In the same way, there are degrees of understanding. For example, agent "A" could claim to understand something about quantum physics, but "A" might nevertheless acknolwedge that "A" does not understand as much as agent "B", who is a quantum physics expert.
It would be wrong to conclude that both A and B had the same degree of understanding of quantum physics. It would also be wrong to conclude that A had no understanding and B had understanding.

You are entitled to your rather strange opinion, but I do not share it.
It can be argued that person X who understands the French language AND empathises strongly with the French people has a better understanding of the French language than person Y who also understands the French language but does not empathise strongly with the French people, but it would be wrong to conclude from this that Y does not understand the French language at all.

Perhaps you need to invent a new English word to encapsulate what you believe to be the case. As far as I am concerned, there are "degrees of understanding", it is not a "black and white" affair. Just as there are degrees of comprehension.
If "understanding of Z" was a black and white affair, then it should be possible to test a person's "understanding of Z" and always achieve either 0% or perfect 100% score (either they do understand Z, or they do not). The world does not work this way (even if you would want your ideal world to work like this, it doesn't).
Quote by quantumcarl
There is a reason there are different words to describe different functions... the differences between the meanings of words are slight.... but they are there for a reason. Terminologies offer subtle shades that help to distinguish the speaker's or writer's references and descriptions.
Single words allow for subtle shades (which you seem to deny). If I say "it is snowing outside", that could mean anything from "there are a few snowflakes drifting about" to "there is a whiteout out there, you cannot see anything because of the blizzard".
An Eskimo might have different words for these two different types of snow, but in English "it is snowing outside" would be correct in both cases. "it is snowing outside" allows different shades in meaning. In the same way "X understands Y" allows for different shades in meaning - it might mean that X has a basic understanding of Y, it might mean that X is an expert in Y.

It is a test based on an explanation; I am saying we have to solve the hard problem first, before we can have a genuine test.
In other words, in absence of an explanation, it makes no sense to test for consciousness? There is thus no logical basis for Searle’s conclusion that the CR does not possess consciousness, correct?
Quote by Tournesol
If manipulating symbols is all there is to understanding, and if consciousness is part of understanding, then there should be a conscious awareness of Chinese in the room (or in Searle's head, in the internalised case).
That is a big “if”. For Searle’s objection to carry any weight, it first needs to be shown that consciousness is necessary for understanding. This has not been done (except by “circulus in demonstrando”, which results in a fallacious argument)
Quote by Tournesol
You could claim that consciousness is not necessarly part of machine understanding; but that would be an admission that the CR's understanding is half-baked compared to human understanding...unless you claim that huamn understanding has nothing to do with consciousness either.
I am claiming that consciousness is not necessary for understanding in all possible agents. Consciousness may be necessary for understanding in humans, but it does not follow from this that this is the case in all possible agents.
To conclude from this that “understanding without consciousness is half baked” is an unsubstantiated anthropocentric (one might even say prejudiced?) opinion.
Quote by Tournesol
But consciousness is a defintional quality of understanding, just as being umarried is being a defintional quality of being a bachelor.
To argue “consciousness is necessary for understanding because understanding is defined such that consciousness is a necessary part of understanding” is a simple example of “circulus in demonstrando”, which results in a fallacious argument.
Quote by Tournesol
If you understand something , you can report that you know it, explain how you know it. etc. That higher-level knowing-how-you-know is consciousness by definition.
I dispute that an agent needs to in detail “know how it knows” in order for it to possess an “understanding of subject X”.
“To know” is “to possess knowledge”. A computer can report that it “knows” X (in the sense that the knowledge X is contained in it’s memory and processes), it might (if it is sufficiently complex) also be able to explain how it came about that it possesses that knowledge. By your definition such a computer would then be conscious?
I think not. imho what you suggest may be necessary, but is not sufficient, for consciousness.
Allow me to speculate.
Consciousness also requires a certain level of internalised self-representation, such that the conscious entity internally manipulates (processes) symbols for “itself” which it can relate to other symbols for objects and processes in the “perceived outside world”; in doing this it creates an internalised representation of itself in juxtaposition to the perceived outside world, resulting in a self-sustaining internal model. This model can have an unlimited number of possible levels of self-reference, such that it is possible that “it knows that it knows”, “it knows that it knows that it knows” etc.

Write down a definition of "red" that a blind person would understand.
Are you suggesting that a blind person would not be able to understand a definition of “red”? Sense-experience (the ability to experience the sensation of red) is a particular kind of knowledge, and is not synonymous with “understanding the concept of red”. Compare with the infamous “What Mary “Didn’t Know”” thought experiment.
Quote by Tournesol
It is perfectly reasonable to suggest that anyone needs normal vision in order to fully understand colour terms in any language.
I disagree. I do not need to have the power of flight to understand aerodynamics. Vision is simply an access to experiential information, a person who “sees red” does not necessarily understand anything about “red” apart from the experiential aspect (which imho is not “understanding”). Experiential information may be used as an aid to understanding in some agents, but I dispute that experiential information is necessary for understanding in all agents.

More restricted in what sense?
Quote by Tournesol
The latter is critical to the ordinary, linguistic understanding of "red".
I dispute that an agent which simply “experiences the sight of red” necessarily underdstands anything about the colour red. I also dispute that “experiencing the sight of red” is necessary to achieve an understanding of red (just as I do not need to be able to fly in order to understand aerodynamics).
Quote by Tournesol
If the "information processing" sense falls short of full human understanding, and I maintain it does, the arguemnt for strong AI founders and Searle makes his case.
And I mainitain it does not. I can converse intelligently with a blind person about the colour “red”, and that person can understand everything there is to know about red, without ever “experiencing the sight of red”. Your argument seems to be that “being able to see red” is necessary for an understanding of red, which is like saying “being able to fly” is necessary for an understanding of flight.

They are necessary to learn the meaning of sensory language ITFP.
They are aids to understanding in the context of some agents (eg human beings), because that is exactly how human beings acquire some of their information. It is not obvious to me that “the only possible way that any agent can learn is via sense-experience”, is it to you?
Quote by Tournesol
if you lack the requisite sense, you cannot attach meaning to sensory language ITFP. If you disagree, define "red" in such a way that a person blind from birth could understand it.
We’ve covered this one already.

Quote by MF
Semantic understanding arises from symbol manipulation. I would claim that the CR could carry out such symbol manipulation.
Perhaps our definitions are a bit mixed here. Since we are talking about Searle's CR I would suggest using his definitions. According to the CR argument symbol manipulation is a purely "syntactic" process (regarding only patterns of information) and that this can not yield a "semantic understanding" (semantic: regarding the meaning of the symbols which is not emergent from the "syntax"[pattern] of the symbols).
The problem that I see with his reasoning as I've stated on the other two threads regarding the CR is that Searle never really defines this "semantic" property. I think you would likely agree with me that this "semantic" understanding arises from complex orders of "syntactic" information (at least in humans if nothing else). I'd have to say that including this adendum I agree with his definitions though obviously not his conclusions (that syntactic information can not yield semantic understanding).
I would have to disagree with you though that "semantic" understanding arises from symbol manipulation in and of itself. I'd have to call it "syntactic" understanding, if any sort of understanding. Unless you are implying more in your definition that isn't explicitly stated. I would agree that "semantic" understanding can develope based off of "syntactic" understanding coupled with experience (or memory, I'm not sure which term would be best suited for my usage here but experience seems to fit better for me personally).
Quote by MF
"experiencing the sensation of seeing red" is NOT tantamount to "understanding what the adjective red means".
Or are you perhaps suggesting that an agent must necessarily possess “sight” in order to understand Chinese?
In fact, are you suggesting even that an agent must possess the faculty of sight in order to understand what is meant by the adjective "red"?
(Note here that I mean "understand" in the literal scientific information-processing sense of to understand what the phenomena are that give rise to the sensation of red, I do NOT mean it in the sense of "I have experienced seeing the colour red, therefore I understand what red is" - this latter is (to me) NOT understanding, it is merely sense-experience)
A blind person perhaps does not know the experience or sensation of seeing red, but that does not mean that person is incapable of any understanding, nor that he/she is incapable of underdstanding what the adjective "red" means.
Our senses are aids to our understanding, they are not the sole and unique source of understanding.
I think I should clarify what I mean by "experience". As I noted earlier I'm not entirely sure if "experience" is better a word to use for what I mean than the word "memory".
What I mean by experience is not the instant of experience as is occurs but rather the accumulation of knowledge through experience (i.e. "Moving Finger has experience in debating"). I see memory as being static imprints of information and experience as an aggregate of memories crossreferanced.
Now "sense-experience". My example of something based on basic sensory information is only a matter of trying to simplify my point and use an "experience" common and easy to understand for us humans with sight. I focus on sensory information because, as far as we know, this is the only manner in which we humans can gather information with which to develope "experience" (with regard to my earlier definition). I do not preclude the possibility of some entity (even a human) to gather information in some other fashion with which to develope an experience and understanding of something. I only mean that the information must reach that enitity in some fashion. In the case of a blind person they have other senses by which to gather information and could possibly come to understand in some sense or another what "red" is but they will not, with out help, be able to understand the experience of "red" that those with sight possess. Here is where the problem comes in...
As I stated before the purpose of language is to communicate the thoughts in a persons head. When a person says the word "red" they generally are not refering to the particular portion of the light spectrum which coresponds to the colour red but their own personal experience of the colour red.
I think I'm tangenting a bit here. Consider this. A blind person has been described in what manner possible what the colour red is. That blind person then under goes a procedure and is endowed with vision. Based solely off of that formerly blind person's knowledge gained about the colour red while blind will that person be able to identify "red" when he/she sees it?
So with regard to your last line. Our senses are, as far as we know, our only source for gaining information. Once we have that information we have it and our senses are no longer necessary to have an understanding of that information (this in regards to the absurd argument of whether or not we still understand if put into a sensory deprivation chamber). No one has said that your eyes are the source for understanding of the colour red, nor has anyone stated that our particular sensing organs are a unique prerequisite for understanding. So please stop with this strawman.
Quote by MF
The CR possesses information inside itself; the CR communicates with words.
I never said that it doesn't possess information did I?
Quote by MF
Your argument seems to be based on the suggestion that the tools in the CR “lack any meaning” because their only purpose “is to shuffle about words”.
I disagree. The purpose of the tools in the CR is “to understand Chinese”.
From what does “meaning” arise?
I would suggest that “meaning” arises simply from a process of symbol manipulation.
On what basis do you claim (ie how can you show) that there is necessarily no “meaning” in the CR?
I never said that the tools lack meaning, in fact I said...
Quote by TheStatutoryApe
The CR (as designed by Searle) has a set of tools with no purpose other than to shuffle them about and hence they lack any meaning aside from the process of shuffling them about as far as the CR is concerned.
There is "syntactic" meaning there just no "semantic". Also I am refering to Searle's argument here specifically and it's flaws. In Searle's argument, no matter the flaws, the CR possesses no understanding. It's built that way. The purpose of the CR is not to "understand chinese" it's to mimic the understanding of chinese.
"Meaning" would be a difficult word to pin down and I have not tried to nor will I attempt to at this juncture. I've never stated that there exists no "meaning" in the CR. I asserted that the CR, as built by Searle, does not understand the meanings of the words it is using. Perhaps a better way of stating this would be to say that the words don't mean to the CR what they mean to people who speak/read chinese.
This is yet another problem with Searle's CR. It is not feasable to produce a computer that can be indestinguishable from a person who "understands" unless it really is capable of understanding. It would not be able to hold a coherant and indestinguishable conversation otherwise.

This may be true of simple pocket calculators, but there is no reason in principle why a "learning calculating machine" could not exist.
MF
Missing my point. I never stated that they couldn't exist or that they couldn't possibly "understand". I'm not arguing the possibility of machines being able to "understand", I'm asking questions about what QuantumCarl, or anyone else here for that matter, thinks are required properties for "understanding".

Do you agree that a dynamic process is necessary for "understanding"?
Do you think that when a human works math problems there is a fundamental differance in the process between the human and a calculator(a normal calculator)? If so what?
Do you think "learning" would be the significant dynamic property required for "understanding" or something else?

Quote by quantumcarl
Biography:
John Searle is an American philosopher who is best known for his work on the human mind and human consciousness. According to Searle, the human mind and human consciousness cannot be reduced simply to physical events and brain states.
Searle is actually a physicalist. He claims that the human brain has unique causal powers to it enable real understanding, thus going beyond formal rules manipulating input.

And the thought experiment isn't called the China room, it's called the Chinese room.

Does the Chinese room possess understanding? It all depends on how you define understanding. In terms of a man understanding words, here is the definition I’ll be using:

  • The man actually knows what the words mean, i.e. that he perceives the meaning of the words, or to put it another way, that he is aware of the truth of what the words mean.

So in this definition, understanding is to be aware of the true meaning of what is communicated. For instance, a man understanding a Chinese word denotes that he is factually aware of what the word means. It is interesting to note that this particular definition of understanding requires consciousness. The definition of consciousness I’ll be using goes as follows:
  • Consciousness is the state of being characterized by sensation, perception, thought, awareness, etc. By the definition in question, if an entity has any of these characteristics the entity possesses consciousness.

To see why (given the terms as defined here) understanding requires consciousness, we can instantiate a few characteristics:
  • Consciousness is the state of being characterized by sensation, perception (of the meaning of words), thought (knowing the meaning of words), awareness (of the meaning of words), etc. By the definition in question, if an entity has any of these characteristics the entity possesses consciousness.

Given this particular definition of understanding, it seems clear that the man in the Chinese room does not know a word of Chinese. What about the systems reply? That the Chinese room as a whole understands Chinese? Searle’s response works well here. Let the man internalize the room and become the system (e.g. he memorizes the rulebook). He may be able to simulate a Chinese conversation, but he still doesn’t understand the language.

Quote by Tournesol
But consciousness is a defintional quality of understanding, just as being
umarried is being a defintional quality of being a bachelor.
That’s what I’ve been telling moving finger. But he doesn’t seem to understand the situation.

Whether or not consciousness is a definitional quality of understanding depends on how you define understanding. In my definition, it certainly is the case (and I suspect the same is true for yours). In moving finger’s definition, that is (apparently) not the case.

Quote by moving finger
To argue “consciousness is necessary for understanding because understanding is defined such that consciousness is a necessary part of understanding” is a simple example of “circulus in demonstrando”, which results in a fallacious argument.
Given the definitions I’ve used, the phrase “understanding requires consciousness” is an analytic statement, and analytic statements are not fallacious. Moving finger, please see post #210 regarding this criticism. Or to save you the trip, I can reproduce my response here.

My definition of understanding requires consciousness. Do we agree? Now please understand what I'm saying here. Do all definitions of understanding require consciousness? I'm not claiming that. Does your definition of understanding require consciousness? I'm not claiming that either. But understanding in the sense that I use it would seem to require consciousness. Do we agree? It seems that we do. So why have we been arguing about this?

You have claimed that “understanding requires consciousness” is circulus demonstrato, a tautology and a fallacious argument. But please understand what’s going on here. Is the tautology “all bachelors are unmarried” a fallacious argument and "circulus in demonstrado"? Obviously not. Analytic statements are not fallacious.

I'd say one is either able to empathize or not. Empathy is generally considered a human trait. However, there are humans who lack the ability through conditioning and genetics.

Quote by moving finger
In the same way, there are degrees of understanding. For example, agent "A" could claim to understand something about quantum physics, but "A" might nevertheless acknolwedge that "A" does not understand as much as agent "B", who is a quantum physics expert.
It would be wrong to conclude that both A and B had the same degree of understanding of quantum physics. It would also be wrong to conclude that A had no understanding and B had understanding.
You use the word undertanding here like you know what it means. In my case I would be saying that "A" has more knowledge about a particular field of quantum physics than "B". Then I would say that there is or can be an understanding between "A" and "B" where they can help each other with certain areas of further study. This will boost their collective comprehension of the ideas of quantum physics.


[QUOTE=moving finger]You believe that empathy comes in binary?

It can be argued that person X who understands the French language AND empathises strongly with the French people has a better understanding of the French language than person Y who also understands the French language but does not empathise strongly with the French people, but it would be wrong to conclude from this that Y does not understand the French language at all.
The act of learning french is an act of empathy with the culture that created the language. Thats it.


Quote by moving finger
As far as I am concerned, there are "degrees of understanding", it is not a "black and white" affair. Just as there are degrees of comprehension.
If I see something that looks like a bear in the woods I then have an "understanding" that there is a bear in the woods. Later on I notice it is not a bear but a brown jacket on a stump. What "degree of understanding" did I have when I thought it was a bear and what "degree of understanding" did I have when I saw it was a jacket on a stump.?

I'd say one is either able to empathize or not.
You are entitled to your opinion, and we will have to agree to disagree
Quote by quantumcarl
I would be saying that "A" has more knowledge about a particular field of quantum physics than "B". Then I would say that there is or can be an understanding between "A" and "B" where they can help each other with certain areas of further study. This will boost their collective comprehension of the ideas of quantum physics.
Can there be, in your opinion, any "understanding" between "A" and "B" where "A" is a Vulcan and "B" is a human being?

Your philosophy would seem to imply that the statement "quantumcarl understands" was either true or false, in each case. Did "quantumcarl understand" when he thought it was a bear? Did he "understand" when he thought it was a jacket?
Then what then happens when he even later discovers it was not a jacket after all, but a brown blanket? Does he now understand?

You seem unable to answer my question. I'm asking how you define degrees of understanding. You're the one proposing they exist and yet, their definition eludes you so far.

I can empathize with your "answer a question with a question" defence because it is a difficult question.

As it goes, in my part of the world, understanding is only understanding when the math or the medical info or the dialect is true information and properly learned. If it is Bulle Shiite and improperly assimilated then, even if the person understands the jumble of information in their own head, no one else will. And after some experiences with this perplexing situation, the person will realize they actually did not understand one bit of the information in their head. The person was taught mis-information and the information has led to a mis-understanding of the topic.

So my definition of understanding is begining to include these elements:

QuantumCarl's guide to Understanding

Correct (true) information
Experience (of that information)
Empathy (of the information)
Consciousness (of all of the above)

Welcome Tisthammerw you have raised some good points. I think the Chinese Room experiment has bit off more than it can chew with regards to the definition of "understanding".

I agree that its definition belongs in the realm of relative semantics however, this discussion has and can continue, in my view, to bring the many uses of the word a little closer together. As I've always stated, terminology exists because professionals need terms that identify origin and function. Words that offer a clear picture of what they describe also offer sound progress and swift decision in the increasingly murky milue of mankind. Thanks!

Quote by TheStatutoryApe
Since we are talking about Searle's CR I would suggest using his definitions.
According to the CR argument symbol manipulation is a purely "syntactic" process (regarding only patterns of information) and that this can not yield a "semantic understanding" (semantic: regarding the meaning of the symbols which is not emergent from the "syntax"[pattern] of the symbols).
With respect, the above is not a “definition”, this is a conclusion (that symbol manipulation cannot give rise to semantic understanding).
If you are saying that the CR cannot have semantic understanding *by definition” then the entire CR argument becomes fallacious (circulus in demonstrando).
Quote by TheStatutoryApe
I would agree that "semantic" understanding can develope based off of "syntactic" understanding coupled with experience (or memory, I'm not sure which term would be best suited for my usage here but experience seems to fit better for me personally).
Therefore symbol manipulation (wth the right information/knowledge base) CAN give rise to semantic understanding? Doesn’t this contradict what you said above?
I agree information and knowledge are also required – I assumed this as a given but can state it explicitly if it helps. “Memory” and “experience” are simply particular (anthropocentric) forms of information and knowledge.
Quote by TheStatutoryApe
I think I should clarify what I mean by "experience". As I noted earlier I'm not entirely sure if "experience" is better a word to use for what I mean than the word "memory".
What I mean by experience is not the instant of experience as is occurs but rather the accumulation of knowledge through experience (i.e. "Moving Finger has experience in debating"). I see memory as being static imprints of information and experience as an aggregate of memories crossreferanced.
In AI terms, simple memory might be equated with information, and experience with knowledge (knowledge = information plus rules of correlation between the information)..
Quote by TheStatutoryApe
In the case of a blind person they have other senses by which to gather information and could possibly come to understand in some sense or another what "red" is but they will not, with out help, be able to understand the experience of "red" that those with sight possess. Here is where the problem comes in...
You use the curious phrase “understand the experience of red”. If I experience seeing red then all I have achieved is that I have experienced seeing red. The experience of seeing red does not in itself convey any understanding, therefore to say that one is able to “understand the experience of red” simply by seeing red is imho misleading.
I dispute that “experiencing seeing red” necessarily endows an “understanding” of red, or that an agent which cannot experience red cannot therefore understand red. Just as the experience of flying does not endow an understanding of flying, and an agent which cannot fly can nevertheless understand flight.
.
Quote by TheStatutoryApe
As I stated before the purpose of language is to communicate the thoughts in a persons head. When a person says the word "red" they generally are not refering to the particular portion of the light spectrum which coresponds to the colour red but their own personal experience of the colour red.
They can relate the word red to a particular subjective sense-experience, yes. But this in itself is not “understanding”.
If I instead say the word “X-ray” (another part of the electromagnetic spectrum), are you then saying that I do not understand what the word means because I have no sense-experience of seeing X-rays?
My understanding of red, and my understanding of X-ray, arise from the information and knowledge that I possess which allows me to put these concepts into rational contextual relationships with other concepts to derive meaning – in other words semantics. I may be blind, but I can understand red just as much as I can understand X-ray.
Quote by TheStatutoryApe
A blind person has been described in what manner possible what the colour red is. That blind person then under goes a procedure and is endowed with vision. Based solely off of that formerly blind person's knowledge gained about the colour red while blind will that person be able to identify "red" when he/she sees it?
This is the infamous Mary argument (Mary knows everything there is to know about red, but has never experienced seeing red). The reason the argument is fallacious is because “experiencing red” is not synonymous with “knowing what red is”. Experiencing red is experiencing red, period. Does Mary know or understand any less about X-rays because she has never experienced seeing X-rays? Of course not.
Quote by TheStatutoryApe
So with regard to your last line. Our senses are, as far as we know, our only source for gaining information.
Yes, but this is a peculiar human limitation, and need not necessarily be the case in all possible agents. I can even speculate of a possible future where humans “acquire information” by direct transfer into the brain, bypassing all the sense organs. Would you say that such information is somehow invalid because it is not experiential information?
Quote by TheStatutoryApe
Once we have that information we have it and our senses are no longer necessary to have an understanding of that information
Senses do not convey or create understanding, they only act as conduits for information transfer.
Understanding is a process that takes place within the brain (or brain equivalent) when it processes information and knowledge in a particular way.
Quote by TheStatutoryApe
No one has said that your eyes are the source for understanding of the colour red,
Pardon? What did you just say above?
Quote by TheStatutoryApe
nor has anyone stated that our particular sensing organs are a unique prerequisite for understanding.
Excellent, so we agree that experiential information is but one possible “source of information” (not of understanding), and an agent does not necessarily need to experience seeing red (or X-rays) in order to understand what is meant by the term red (or X-rays)?
.
Quote by TheStatutoryApe
There is "syntactic" meaning there just no "semantic".
It has not been shown that there is no semantic meaning present, except possibly by definition (which as we have seen results in a fallacious argument)
Quote by TheStatutoryApe
The purpose of the CR is not to "understand chinese" it's to mimic the understanding of chinese.
Understanding is a process. In terms of what the process achieves, there is no difference between “a process” and “a perfect simulation of that process”. If you think there is, Please explain why a perfect simulation of a process necessarily differs in any way from the original process?
Quote by TheStatutoryApe
I asserted that the CR, as built by Searle, does not understand the meanings of the words it is using.
Perhaps you have asserted this, but you have not shown it.
I can assert anything I wish, but in absence of rational and logical argument that is simply my opinion.
Quote by TheStatutoryApe
Perhaps a better way of stating this would be to say that the words don't mean to the CR what they mean to people who speak/read chinese.
Where has this been shown, and why should it matter anyway?
You and I do not share “perfect definitions of all the words we use” (we dispute some meanings of words in this thread), but that does not entitle either of us to accuse the other of not understanding English.
Quote by TheStatutoryApe
This is yet another problem with Searle's CR. It is not feasable to produce a computer that can be indestinguishable from a person who "understands" unless it really is capable of understanding.
And how would you know whether or not it is really capable of understanding, and not just (as you suggest) simulating understanding? How would you tell the difference?
Quote by TheStatutoryApe
It would not be able to hold a coherant and indestinguishable conversation otherwise.
The CR can hold a coherent and intelligent conversation. (not sure what you mean by “indistinguishable conversation”?). What do we conclude from this?

One more note:

I've noticed that no one, other than myself, has broken down the word understanding into its two roots

under



standing



Imagine who came up with this word and what it represented to them when they brought these two roots together.

Any thoughts?

Quote by TheStatutoryApe
Do you agree that a dynamic process is necessary for "understanding"?
It is not that a “dynamic process is necessary for understanding”, understanding IS a dynamic process (which is why questions such as “can a pile of bricks understand” demonstrate a profound lack of understanding of the meaning of “undertanding” on the part of the questioner)

Quote by TheStatutoryApe
Do you think that when a human works math problems there is a fundamental differance in the process between the human and a calculator(a normal calculator)? If so what?
There are many fundamental differences, yes. For example in the case of the human agent the process is likely to be ill-defined, rather erratic and irrational (depending on the complexity of the problem), ie will not necessarily follow a rational and easily reproducible algorithm, and will be accompanied by many auxiliary or associated side-processes. In the case of the simple machine agent the algorithm is likely to be (in comparison) very rational, straightforward and easily reproducible. Is this what you mean?

Quote by TheStatutoryApe
Do you think "learning" would be the significant dynamic property required for "understanding" or something else?
Please define what you mean by “learning”. It could mean “acquiring new knowledge”. Understanding requires a knowledge-base, therefore (following the above definition) an agent with the capacity to understand, but which does not understand because it lacks a suitable knowledge-base, might achieve understanding by learning. Is this what you mean?

You believe that empathy comes in binary?
Quote by quantumcarl
I don't know where you get that idea.
Let me explain. In other words Quantumcarl (QC) believes an agent either has perfect empathy (1) or it does not have any empathy at all (0). Nothing “in between” is poossible? Yes or no?
Quote by moving finger
Your philosophy would seem to imply that the statement "quantumcarl understands" was either true or false, in each case. Did "quantumcarl understand" when he thought it was a bear? Did he "understand" when he thought it was a jacket?
Then what then happens when he even later discovers it was not a jacket after all, but a brown blanket? Does he now understand?
Quote by quantumcarl
You seem unable to answer my question.
You misunderstand (or jump to conclusions). I “chose” not to answer your question, just as it seems that you choose not to answer most of the questions in my last post.
Quote by quantumcarl
I'm asking how you define degrees of understanding.
Then why didn’t you just say so?
“degrees of understanding” means “two agents can understand subject X, yet one agent may have more understanding of X than the other”.
Consider the statement “Agent A possess more understanding of subject X than does Agent B, and yet both agents still possess some understanding of subject X”. These are “degrees of understanding”. Quantumcarl’s philosophy would seem to be that the above statement is necessarily false (ie the situation described is impossible).
Quote by quantumcarl
it is a difficult question.
Perhaps for QC, not for MF. It’s a very easy question, and I just answered it. Now I’ll wait to see if you answer the questions I posed in my earler post.
Quote by quantumcarl
understanding is only understanding when the math or the medical info or the dialect is true information and properly learned.
Classical error.
“True information”? What is that? Does QC possess true information, or does QC just think/believe that QC does? How would QC find out?
A) When QC saw the bear, did he possess true information?
B) When QC realised it was a jacket and not a bear, did he now possess true information?
C) When quantumcarl QC realised it was a blanket and not a jacket, did he now possess true information?
All we can ever possess is epistemic information. We may try to infer ontically from this, but we never have direct access to ontic information. Thus the best we can ever achieve is to “believe that we have true information”. In each case of A, B and C above, QC believed (at the time) that it possessed true information.
If QC insists that QC must possess true information in order to understand (as opposed to simply believing that QC possesses true information) then QC will never be able to demonstrate that QC understands, because QC will never be able to demonstrate unequivocally and objectively that QC possesses true information.
Quote by quantumcarl
If it is Bulle Shiite and improperly assimilated then, even if the person understands the jumble of information in their own head, no one else will.
Does QC claim to possess true information? How would QC test this?
Quote by quantumcarl
Correct (true) information
Does QC claim to possess true information? How would QC test this?
If QC is unable to prove that QC possesses true information, does it follow that QC does not understand anything?
Quote by quantumcarl
Experience (of that information)
Experience is a possible source of information. Experience provides information. But I dispute that an agent needs experience in order to understand.

Quote by Tisthammerw
Does the Chinese room possess understanding? It all depends on how you define understanding.
Excellent start!
Now allow me to summarise the fundamental problem as I see it.
Take the conditional statement :
IF consciousness is necessary for understanding THEN it follows that an agent which does not possess consciousness also does not possess understanding.
I hope that everyone here agrees with this statement?
The question that remains to be answered is then : Is consciousness necessary for understanding?
How do we tackle this problem?
First, to construct an argument, we need to state our premises.
We might DEFINE UNDERSTANDING such that understanding requires consciousness. Since in this case we have not SHOWN that understanding requires consciousness, but instead we have DEFINED understanding this way, this definition then becomes one of our premises.
What this gives us is then :
1 Premise : We define understanding such that it requires consciousness
2 IF consciousness is necessary for understanding THEN it follows that an agent which does not possess consciousness also does not possess understanding.
3 Consciousness is necessary for understanding (from Premise 1)
4 Hence an agent which does not possess consciousness also does not possess understanding (from 2,3)
The above argument is an example of “circulus in demonstrando”, ie we have assumed what we wish to prove (that consciousness is necessary for understanding) in our premises, and (though the logic of the argument is perfect) it is a fallacious argument.
Quote by Tisthammerw
Given the definitions I’ve used, the phrase “understanding requires consciousness” is an analytic statement, and analytic statements are not fallacious.
With respect, I did not say the statement “understanding requires consciousness” is fallacious.
The statement “understanding requires consciousness” is also a premise.
I said the ARGUMENT is fallacious. Do you understand the difference between an argument and a statement and a premise?
Quote by Tisthammerw
My definition of understanding requires consciousness. Do we agree?
I agree that you have chosen to define understanding such that it requires consciousness.
Quote by Tisthammerw
Now please understand what I'm saying here. Do all definitions of understanding require consciousness? I'm not claiming that.
Excellent.
Quote by Tisthammerw
Does your definition of understanding require consciousness? I'm not claiming that either.
Excellent.
Quote by Tisthammerw
But understanding in the sense that I use it would seem to require consciousness. Do we agree?
You have defined it so
Quote by Tisthammerw
It seems that we do. So why have we been arguing about this?
You misunderstand. We are NOT arguing about your premise “understanding requires consciousness”.
We seem to disagree on whether the following ARGUMENT is fallacious or not :
“we take as a premise that understanding requires consciousness, it follows that a non-conscious agent is unable to understand”
This argument is a perfect example of “circulus in demonstrando”, ie the conclusion of the argument is already assumed in the premises, which is accepted in logic as being a fallacious argument.
Quote by Tisthammerw
You have claimed that “understanding requires consciousness” is circulus demonstrato, a tautology and a fallacious argument.
Again, I have NOT claimed the statement “understanding requires consciousness” is “circulus in demonstrando” – you seem confused about the difference between a statement and an argument.
Let me repeat again :
The following argument is an example of “circulus in demonstrando”, and is fallacious :
“we take as a premise that understanding requires consciousness, it follows that a non-conscious agent is unable to understand”
Quote by Tisthammerw
Is the tautology “all bachelors are unmarried” a fallacious argument and "circulus in demonstrado"?
Let’s look at it logically.
“all bachelors are unmarried” is not necessarily an argument. It could be a statement or a premise, or both.
To construct an argument we first need to state our premises, then we draw inferences from those premises, then we make a conclusion from the inferences and premises.

Let's do this.
First one must define what one means by the terms “bachelor”, and “unmarried”. (you may object "this is obvious", but that is beside the point. Strictly all terms in an argument must be clearly defined and agreed).
These definitions then become part of the premises to the argument.
If the conclusion of the argument is already contained in the premises, then by definition the argument is fallacious, by “circulus in demonstrando”.
For example :
"we take as a premise that "bachelor" is defined as an "unmarried male", it follows that the statement "all bachelors are unmarried" is true"
The above argument is completely logical, but fallacious due to “circulus in demonstrando”

Check it out yourself in any good book on logic, if you don’t believe me.
May your God go with you

Quote by Tournesol
But consciousness is a defintional quality of understanding
Quote by Tisthammerw
That’s what I’ve been telling moving finger.
Quote by Tisthammerw
Whether or not consciousness is a definitional quality of understanding depends on how you define understanding. In my definition, it certainly is the case (and I suspect the same is true for yours). In moving finger’s definition, that is (apparently) not the case.
Let’s try to take this one step at a time, to see if we can make progress.

Do we all (MF, Tournesol and Tisthammerw) agree that the following statement is true?

“whether or not consciousness is necessary for understanding is a matter of definition

True or false?

MF

(ps MF says imho it is true)

Hi quantumcarl

I am conscious that our debate often gets so convoluted that we maybe lose sight of exactly what the issues are that we are debating.

Just to be sure that I properly understand (or should that be comprehend?) your position, and to make sure that I am not attacking something that is simply in my imagination, could you please examine the following statement :

Statement : "It is the case that a human being EITHER has complete understanding of the subject X, OR has no understanding of the subject X - there are NO "shades of grey" whereby a human being might have a partial understanding of the subject X."

(subject X could be the French language, for example)

Would quantumcarl agree that the above statement (according to quantumcarl's defininition of understanding) is true, or false?

Many thanks

MF
