> If you, being structural elements of some logical pattern, had no idea of what you were doing, then can we really argue about the ‘thoughts’ of electronic devices made of different parts which are deemed incapable of any thinking even by the most fervent followers of the electronic-brain concept? You know all these parts: radio tubes, semiconductors, magnetic matrixes, etc. I think our game gave us the right answer to the question ‘Can machines think?’ We’ve proven that even the most perfect simulation of machine thinking is not the thinking process itself, which is a higher form of motion of living matter.

> For all I know, Searle may only be behaving as if he were thinking deeply about these matters. But, even though I disagree with him, his simulation is pretty good, so I’m willing to credit him with real thought.
I'm not sure that is the right word, at least for me.
I teach, and every once in a while a person asks a question that I just do not understand. It is a bad feeling; I am left standing in front of everyone saying "Could you repeat it in other words? Could you give another example?"
I have that same feeling on reading Searle's paper, and on hearing him talk about it on In Our Time. He says a number of things that I agree with. Then he says, "Therefore obviously computers cannot understand Chinese." I'm left slackjawed, wondering whether some kind of type error happened or am I just too dumb? (Entirely possible, no doubt.)
I don't have the `vapid' sense that I understand the argument and it is incorrect, rather I'm left with a sense of "What just happened?"
The other issue in philosophy of mind is intentionality, which is how any physical system can be about something. Humans are both conscious and possess beliefs, desires and what not.
There is no meaningful difference here either. Physical systems also have bounded information content as per the Bekenstein Bound.
> The other issue in philosophy of mind is intentionality, which is how any physical system can be about something
I don't see the great disconnect here either. You have to treat systems of general intelligence as if they have intentions. What else is there?
But that was not my point. Digital computers could be, in principle, conscious, but the idea that you can construct a mind by making a symbolic program is flawed. Human brain could be, in fact, a digital computer, but the mind in it is not a result of some vulgar symbolic computation, but a result of some mysterious computational process, that very possibly has nothing to do with manipulations with some abstract symbols.
Gee, I come to the opposite conclusion. If we define what can be computed as what can be computed as a TM then we are TM's, that is, computers. I understand Searle to instead be offering an argument that humans are not TM's, that there is an aspect of computing in the world that is not captured by the definition that Turing gave, and it is whatever is involved in understanding.
But the argument, as I hear it, concludes with something like "and it is obviously wrong to think this is what we are doing when we feel we understand something." That's not obvious, to me.
> some vulgar symbolic computation
I guess I still don't get it. I've not seen any evidence that what goes on between my ears is not doable this way, but I am very ready to concede that the jury is still out. I just don't understand the part where Searle says "obvious."
We're not even Turing machines. The Bekenstein Bound establishes humans as finite state automata.
> Human brain could be, in fact, a digital computer, but the mind in it is not a result of some vulgar symbolic computation, but a result of some mysterious computational process, that very possibly has nothing to do with manipulations with some abstract symbols.
So a magical computer? What purpose in a brains computation does the magic serve exactly?
For an updated overview of the argument and replies, see: https://plato.stanford.edu/entries/chinese-room/
"My response to the systems theory is quite simple: let the individual internalize all of these elements of the system. He memorizes the rules in the ledger and the data banks of Chinese symbols, and he does all the calculations in his head. The individual then incorporates the entire system. There isn't anything at all to the system that he does not encompass. We can even get rid of the room and suppose he works outdoors. All the same, he understands nothing of the Chinese, and a fortiori neither does the system, because there isn't anything in the system that isn't in him. If he doesn't understand, then there is no way the system could understand because the system is just a part of him."
Searle does not seem to understand that the systems reply is not dependent on where or how the components of the system are implemented. He apparently cannot conceive that, while the subject's conscious mind is solely occupied with mechanically performing the operations of the algorithm, the system that her conscious mind is part of actually understands something, and that this would be so even if the system were implemented entirely within the physical body of the subject. It is an outlandish concept, but the premise of the experiment is itself outlandish, and a philosopher should not expect ordinary intuitions to be a reliable guide to what would happen in such cases.
The SEP entry mentions Schaeffer (2009) and Nute (2011) for the line of disagreement extending into a discussion of modality.
Regarding the second line of argument, the entry mentions Harnad (2012) and says that he appears to follow Searle in, "linking understanding and states of consciousness" as well as arguing "that the core problem of conscious "feeling" requires sensory connections to the real world."
The primary issue in all of this is whether certain non-biological systems (i.e. a computer) are sufficient for the understanding generated by certain biological systems (i.e. humans). This has not much of anything to do with physicalism or dualism, no matter what certain responses by non-experts (Penrose, Kurzweil, etc.) would have some believe. The fact that Cole even mentions Kurzweil is, arguably, a disservice to those outside the relevant domain.
The take-away is this: in analytical philosophy, many famous thought experiments are important not for their intended conclusions, but for the expanded dialectic they generate, and which lasts for decades (if not longer). The expanded dialectic brings additional clarity and raises important questions that had either gone unnoticed or were impossible to see before the thought experiment.
There is a small minority of individuals on both sides that seem to want to slow scientific progress (whether intentionally or not). Now, the vast majority of the time it is presumed people like Searle fit this description. People like Dennett fit this description as well, though. Anyone truly making definitive claims about having resolved the question of (say) conciousness, is not taking the right tack from a scientific perspective.
No-one ever disproved vitalism, but its implicit threat to the progress of biology simply dropped by the wayside.
His real argument exists in a bunch of stuff he wrote about intentionality (the real argument probably still fails - but it's more nuanced than the Chinese room stuff everyone talks about).
If you want a really good paper about the problems around machines and minds check out "Troubles with Functionalism" by Ned Block
...written in 1984. I do not believe we've made any progress in terms of creating "responsible machines."
My general feeling about the Chinese Room argument is that it discusses the "psychological phenomenon of understanding." We don't really know what that phenomenon is, it's a feeling or sensation from our perspective (or at least from mine) and so I'm uncomfortable ascribing much importance to it. Until we understand how our minds actually work, the "Turing test approach" makes sense to me: if we can't tell the difference, then it's "responsible."
Clearly?
Suffice it to say that we didn't have a clue back then and we dont' have a clue now, either. We don't have any good model of human intelligence. We don't understand it. We can't reproduce it. We dont' know how.
And if you think that modern AI research is closer to that target because we now have good classifiers- well, think again. In the past, we had good inference engines. We had good ways to reason with uncertainty. All those things are useful, and they may even be components of intelligence, but they do not, on their own, constitute intelligence.
Clearly.
If you mean symbolic in the sense that computers use symbols, then no, it won't involve that. Humans are self-reflective (at least some of the time), and they don't think that way (with the possible exception of mathematicians).
But words can also be considered symbols, and when we think, we usually think in terms of words. "I" is a symbol, and it's hard to self-reflect without using it.
If you're not emotionally invested that argument is laughable. It's total basis is that human suck at math.
AI researchers always used the tools that all scientists use to model their subject, in this case, intelligence: maths. Logic is maths, just as probabilities, calculus, algebra, etc etc.
Why not? Not consciously, but as part of the underlying process that produces consciousness. Particles and fields that make upboir brains carry no more intrinsic meaning than the charged bits in digitial computers.
What did the ouroboros say to John Searle?
"Let me out of here, you know I can't speak chinese!"
