chinese room argument

Searle asks you to imagine the following scenario** : … [4] However, several concepts developed by computer scientists are essential to understanding the argument, including symbol processing, Turing machines, Turing completeness, and the Turing test. Not Strong AI (by the Chinese room argument). Ned Block's Blockhead argument[91] suggests that the program could, in theory, be rewritten into a simple lookup table of rules of the form "if the user writes S, reply with P and goto X". Searle writes "syntax is insufficient for semantics."[78][x]. The argument centers on a thought experiment in which someone who Alternately put, equivocation on “Strong AI” invalidates the would-be dilemma that Searle’s intitial contrast of “Strong AI” to “Weak AI” seems to pose: Strong AI (they really do think) or Weak AI (it’s just simulation). They may be interpreted in two ways: either they claim (1) this technology is required for consciousness, the Chinese room does not or cannot implement this technology, and therefore the Chinese room cannot pass the Turing test or (even if it did) it would not have conscious understanding. So, when a computer responds to some tricky questions by a human, it can be concluded, in accordance with Searle, that we are communicating with the programmer, the person who gave the computer, a certain set of instructions … Nevertheless, Searle frequently and vigorously protests that he is not any sort of dualist. It is one of the best known and widely credited counters to claims of artificial intelligence (AI)—that is, to claims that computers do or at least can (someday might) think. 1950. (6) Confusion on the preceding point is fueled by Searle’s seemingly equivocal use of the phrase “strong AI” to mean, on the one hand, computers really do think, and on the other hand, thought is essentially just computation. It takes Chinese characters as input and, by following the instructions of a computer program, produces other Chinese characters, which it presents as output. What is it like to be a bat? Since “it is not conceivable,” Descartes says, that a machine “should produce different arrangements of words so as to give an appropriately meaningful answer to whatever is said in its presence, as even the dullest of men can do” (1637, Part V), whatever has such ability evidently thinks. . [b], The definition depends on the distinction between simulating a mind and actually having a mind. The connectionist reply emphasizes that a working artificial intelligence system would have to be as complex and as interconnected as the human brain. In the 2016 video game The Turing Test, the Chinese Room thought experiment is explained to the player by an AI. We don't complain that 'it isn't really a calculator', because the physical attributes of the device do not matter. One tack, taken by Daniel Dennett (1980), among others, decries the dualistic tendencies discernible, for instance, in Searle’s methodological maxim “always insist on the first-person point of view” (Searle 1980b, p. 451). He wrote: I do not wish to give the impression that I think there is no mystery about consciousness. U. S. A. His framing of the Chinese room seems rather arbitrary. Searle argues that, without "understanding" (or "intentionality"), we cannot describe what the machine is doing as "thinking" and, since it does not think, it does not have a "mind" in anything like the normal sense of the word. "The overwhelming majority", notes BBS editor Stevan Harnad,[f] "still think that the Chinese Room Argument is dead wrong". . If the computer had passed the Turing test this way, it follows, says Searle, that he would do so as well, simply by running the program manually. Alan Turing writes, "all digital computers are in a sense equivalent. Furthermore, since in the thought experiment “nothing . But they make the mistake of supposing that the computational model of consciousness is somehow conscious. Marcus Du Sautoy tries to find out using the Chinese Room Experiment. It seemed to me that the Chinese room was now separated from me by two walls and windows. If we “put a computer inside a robot” so as to “operate the robot in such a way that the robot does something very much like perceiving, walking, moving about,” however, then the “robot would,” according to this line of thought, “unlike Schank’s computer, have genuine understanding and other mental states” (1980a, p. 420). . This is not science fiction, but real science, based on a theoretical conception as deep as it is daring: namely, we are, at root, computers ourselves."[25]. The computer manipulates the symbols using a form of syntax rules, without any knowledge of the symbol's semantics (that is, their meaning). The question Searle wants to answer is this: does the machine literally "understand" Chinese? 5); and since he acknowledges the possibility that some “specific biochemistry” different than ours might suffice to produce conscious experiences and consequently intentionality (in Martians, say), and speaks unabashedly of “ontological subjectivity” (see, e.g., Searle 1992, p. 100); it seems most natural to construe Searle’s positive doctrine as basically dualistic, specifically as a species of “property dualism” such as Thomas Nagel (1974, 1986) and Frank Jackson (1982) espouse. On the other hand, such a lookup table would be ridiculously large (to the point of being physically impossible), and the states could therefore be extremely specific. This too, Searle says, misses the point: it “trivializes the project of Strong AI by redefining it as whatever artificially produces and explains cognition” abandoning “the original claim made on behalf of artificial intelligence” that “mental processes are computational processes over formally defined elements.” If AI is not identified with that “precise, well defined thesis,” Searle says, “my objections no longer apply because there is no longer a testable hypothesis for them to apply to” (1980a, p. 422). All participants are separated from one another. Can a computer really understand a new language? I have inputs and outputs that are indistinguishable from those of the native Chinese speaker, and I can have any formal program you like, but I still understand nothing.” “For the same reasons,” Searle concludes, “Schank’s computer understands nothing of any stories” since “the computer has nothing more than I have in the case where I understand nothing” (1980a, p. 418). Searle argues that even a super-intelligent machine would not necessarily have a mind and consciousness. So they are meaningful; and so is Searle’s processing of them in the room; whether he knows it or not. Searle offers rejoinders to these various replies. Behavioristic hypotheses deny that anything besides acting intelligent is required. Searle's response: The Chinese room argument attacks the claim of strong AI that understanding only requires formal processes operating on formal symbols. "[101] These replies question whether Searle is justified in using his own experience of consciousness to determine that it is more than mechanical symbol processing. The Other Minds Reply reminds us that how we “know other people understand Chinese or anything else” is “by their behavior.” Consequently, “if the computer can pass the behavioral tests as well” as a person, then “if you are going to attribute cognition to other people you must in principle also attribute it to computers” (1980a, p. 421). "[73] He takes it as obvious that we can detect the presence of consciousness and dismisses these replies as being off the point. Inaddition, Searle’s article in BBSwas published alongwith comments and criticisms by 27 cognitive science researchers.These 27 comments were followed by Searle’s replies to hiscritics. In reply to this second sort of objection, Searle insists that what’s at issue here is intrinsic intentionality in contrast to the merely derived intentionality of inscriptions and other linguistic signs. Initial Objections & Replies to the Chinese room argument besides filing new briefs on behalf of many of the forenamed replies(for example, Fodor 1980 on behalf of “the Robot Reply”) take, notably, two tacks. He writes that, in order to consider the "system reply" as remotely plausible, a person must be "under the grip of an ideology". (C4) The way that human brains actually produce mental phenomena cannot be solely by virtue of running a computer program. He writes "Some have made a cult of speed and timing, holding that, when accelerated to the right speed, the computational may make a phase transition into the mental. [37] Biological naturalism is similar to identity theory (the position that mental states are "identical to" or "composed of" neurological events); however, Searle has specific technical objections to identity theory. Nobody supposes that the computational model of rainstorms in London will leave us all wet. [6][c] Searle calls the first position "strong AI" and the latter "weak AI".[d]. The argument asks the reader to imagine a computer that is programmed to understand how to read and communicate in Chinese. The derivation, according to Searle’s 1990 formulation proceeds from the following three axioms (1990, p. 27): (A1) Programs are formal (syntactic). So, when the Chinese expert on the other end of the room is verifying the answers, he actually is communicating with another mind which thinks in Chinese. They have a book that gives them an appropriate response to each series of symbols that appear in the chat. [ad] The Chinese room has all the elements of a Turing complete machine, and thus is capable of simulating any digital computation whatsoever. [3][30] Functionalism is a position in modern philosophy of mind that holds that we can define mental phenomena (such as beliefs, desires, and perceptions) by describing their functions in relation to each other and to the outside world. Instead of shuffling symbols, we “have the man operate an elaborate set of water pipes with valves connecting them.” Given some Chinese symbols as input, the program now tells the man “which valves he has to turn off and on. Discourse on method. To Searle, as a philosopher investigating in the nature of mind and consciousness, these are the relevant mysteries. Includes chapters by, This page was last edited on 28 November 2020, at 22:54. [14], Most of the discussion consists of attempts to refute it. Or the symbols? Searle’s own hypothesis of Biological Naturalism may be characterized sympathetically as an attempt to wed – or unsympathetically as an attempt to waffle between – the remaining dualistic and identity-theoretic alternatives. This, according to those who make this reply, shows that Searle's argument fails to prove that "strong AI" is false. Searle responds that such a mind is, at best, a simulation, and writes: "No one supposes that computer simulations of a five-alarm fire will burn the neighborhood down or that a computer simulation of a rainstorm will leave us all drenched. Searle believes that human beings directly experience their consciousness, intentionality and the nature of the mind every day, and that this experience of consciousness is not open to question. Block, Ned. [60] However, from Searle's perspective, this argument is circular. However, Searle himself would not be able to understand the conversation. 2), who “shows in detail how to construct a computer using a roll of toilet paper and a pile of small stones” (Searle 1980a, p. 423). Arguments of this form, according to Stevan Harnad, are "no refutation (but rather an affirmation)"[49] of the Chinese room argument, because these arguments actually imply that no digital computers can have a mind. As Searle writes "the systems reply simply begs the question by insisting that the system must understand Chinese."[29]. Searle argues that however the program is written or however the machine is connected to the world, the mind is being simulated by a simple step-by-step digital machine (or machines). . It takes Chinese as input, it simulates the formal structure of the synapses of the Chinese brain, and it gives Chinese as output. Identification of thought with consciousness along these lines, Searle insists, is not dualism; it might more aptly be styled monist interactionism (1980b, p. 455-456) or (as he now prefers) “biological naturalism” (1992, p. 1). And so seems that, in recent … But if the Chinese room really "understands" what it is saying, then the symbols must get their meaning from somewhere. The Chinese room argument can be seen as an argument in support of premise 3. It is simply not possible to divine whether a conscious agency or some clever simulation inhabits the room. Though Searle unapologetically identifies intrinsic intentionality with conscious intentionality, still he resists Dennett’s and others’ imputations of dualism. Newell and Simon had conjectured that a physical symbol system (such as a digital computer) had all the necessary machinery for "general intelligent action", or, as it is known today, artificial general intelligence. Though it would be “rational and indeed irresistible,” he concedes, “to accept the hypothesis that the robot had intentionality, as long as we knew nothing more about it” the acceptance would be simply based on the assumption that “if the robot looks and behaves sufficiently like us then we would suppose, until proven otherwise, that it must have mental states like ours that cause and are expressed by its behavior.” However, “[i]f we knew independently how to account for its behavior without such assumptions,” as with computers, “we would not attribute intentionality to it, especially if we knew it had a formal program” (1980a, p. 421). "[65] Nicholas Fearn responds that, for some things, simulation is as good as the real thing. They framed this as a philosophical position, the physical symbol system hypothesis: "A physical symbol system has the necessary and sufficient means for general intelligent action. Specifically, the argument is intended to refute a position Searle calls strong AI: "The appropriately programmed computer with the right inputs and outputs would thereby have a mind in exactly the same sense human beings have minds. While Searle is trapped in the room, the virtual mind is not: it is connected to the outside world through the Chinese speakers it speaks to, through the programmers who gave it world knowledge, and through the cameras and other sensors that roboticists can supply. [10] Leibniz found it difficult to imagine that a "mind" capable of "perception" could be constructed using only mechanical processes. The brain arguments in particular deny strong AI if they assume that there is no simpler way to describe the mind than to create a program that is just as mysterious as the brain was. David Cole combines the second and third categories, as well as the fourth and fifth. . The commonsense knowledge reply emphasizes that any program that passed a Turing test would have to be "an extraordinarily supple, sophisticated, and multilayered system, brimming with 'world knowledge' and meta-knowledge and meta-meta-knowledge", as Daniel Dennett explains.[76]. Searle-in-the-room behaves as if he understands Chinese; yet doesn’t understand: so, contrary to Behaviorism, acting (as-if) intelligent does not suffice for being so; something else is required. Imagine, the argument goes, that someone is locked inside a room. It has been widely discussed in the years since. Indeed, Searle accuses strong AI of dualism, writing that "strong AI only makes sense given the dualistic assumption that, where the mind is concerned, the brain doesn't matter. "[46][47] The Chinese room argument does not refute this, because it is framed in terms of "intelligent action", i.e. These arguments (and the robot or commonsense knowledge replies) identify some special technology that would help create conscious understanding in a machine. Therefore, he concludes that the "strong AI" hypothesis is false. But in imagining himself to be the person in the room, Searle thinks it’s “quite obvious . “Reply to Jacquette.”, Searle, John. Chinese Room Argument The Chinese room argument is a thought experiment of John Searle (1980a) and associated (1984) derivation. Or is the mind like the rainstorm, something other than a computer, and not realizable in full by a computer simulation? Against this, Searle insists, “even getting this close to the operation of the brain is still not sufficient to produce understanding” as may be seen from the following variation on the Chinese room scenario. . [r], However, the thought experiment is not intended to be a reductio ad absurdum, but rather an example that requires explanation. [citation needed], The Chinese Room is also the name of a British independent video game development studio best known for working on experimental first-person games, such as Everybody's Gone to the Rapture, or Dear Esther.[115]. In the first case, where features like a robot body or a connectionist architecture are required, Searle claims that strong AI (as he understands it) has been abandoned. Stevan Harnad argues that Searle's depictions of strong AI can be reformulated as "recognizable tenets of computationalism, a position (unlike "strong AI") that is actually held by many thinkers, and hence one worth refuting. “Could a machine think?”, Dennett, Daniel. Each water connection corresponds to a synapse in the Chinese brain, and the whole system is rigged up so that after doing all the right firings, that is after turning on all the right faucets, the Chinese answers pop out at the output end of the series of pipes. Kurzweil is concerned primarily with the amount of intelligence displayed by the machine, whereas Searle's argument sets no limit on this. Or they may be claiming that (2) it is easier to see that the Chinese room has a mind if we visualize this technology as being used to create it. Hew cited examples from the USS Vincennes incident.[42]. He writes that we must "presuppose the reality and knowability of the mental. Searle's "strong AI" should not be confused with "strong AI" as defined by Ray Kurzweil and other futurists,[43] who use the term to describe machine intelligence that rivals or exceeds human intelligence. Etc. In short, executing an algorithm cannot be sufficient for thinking. . He drew an analogy between a commander in their command center and the person in the Chinese Room, and analyzed it under a reading of Aristotle’s notions of "compulsory" and "ignorance". Therefore, he argues, it follows that the computer would not be able to understand the conversation either. Contrary to “strong AI,” then, no matter how intelligent-seeming a computer behaves and no matter what programming makes it behave that way, since the symbols it processes are meaningless (lack semantics) to it, it’s not really intelligent. The Chinese room argument is a central concept in Peter Watts's novels Blindsight and (to a lesser extent) Echopraxia. The Chinese Room Argument First published Fri Mar 19, 2004; substantive revision Tue Sep 22, 2009 The Chinese Room argument, devised by John Searle, is an argument against the possibility of true artificial intelligence. In response to Searle's well-known Chinese room argument against Strong AI (and more generally, computationalism), Harnad proposed that if the … But I do not think these mysteries necessarily need to be solved before we can answer the question with which we are concerned in this paper.[45]. (A2) Minds have mental contents (semantics). Gottfried Leibniz made a similar argument in 1714 against mechanism (the position that the mind is a machine and nothing more). That their behavior seems to evince thought is why there is a problem about AI in the first place; and if Searle’s argument merely discountenances theoretic or metaphysical identification of thought with computation, the behavioral evidence – and consequently Turing’s point – remains unscathed. To all of the questions that the person asks, it makes appropriate responses, such that any Chinese speaker would be convinced that they are talking to another Chinese-speaking human being. More sophisticated versions of the systems reply try to identify more precisely what "the system" is and they differ in exactly how they describe it. . This assumption, he argues, is not tenable given our experience of consciousness. Not knowing which is which, a human interviewer addresses questions, on the one hand, to a computer, and, on the other, to a human being. "When we call up the pocket calculator function on a desktop computer, the image of a pocket calculator appears on the screen. At least in principle, any program can be rewritten (or "refactored") into this form, even a brain simulation. The Chinese room is designed to show that the Turing test is insufficient to detect the presence of consciousness, even if the room can behave or function as a conscious mind would. The Many Mansions Reply suggests that even if Searle is right in his suggestion that programming cannot suffice to cause computers to have intentionality and cognitive states, other means besides programming might be devised such that computers may be imbued with whatever does suffice for intentionality by these other means. (2) The Chinese room experiment, as Searle himself notices, is akin to “arbitrary realization” scenarios of the sort suggested first, perhaps, by Joseph Weizenbaum (1976, Ch. He presented the first version in 1984. Philosopher John Searle formulated the Chinese room argument to discredit the idea that a computer can be programmed with the appropriate functions to behave the same way a human mind would. . But the man certainly doesn't understand Chinese, and neither do the water pipes, and if we are tempted to adopt what I think is the absurd view that somehow the conjunction of man and water pipes understands, remember that in principle the man can internalize the formal structure of the water pipes and do all the "neuron firings" in his imagination.[82]. "[7], The claim is implicit in some of the statements of early AI researchers and analysts. [15] Varol Akman agrees, and has described the original paper as "an exemplar of philosophical clarity and purity". They point out that, by Searle's own description, these causal properties can't be detected by anyone outside the mind, otherwise the Chinese Room couldn't pass the Turing test—the people outside would be able to tell there wasn't a Chinese speaker in the room by detecting their causal properties. He did not believe this was relevant to the issues that he was addressing. Functionalistic hypotheses hold that the intelligent-seeming behavior must be produced by the right procedures or computations. This Chinese Room thought experiment was a response to the Turing Test. “Intrinsic Intentionality.”, Searle, John. The Chinese room argument leaves open the possibility that a digital machine could be built that acts more intelligently than a person, but does not have a mind or intentionality in the same way that brains do. “Is the Brain’s Mind a Computer Program?”, Turing, Alan. The Chinese Room Argument, by John Searle, is one of the most important thought experiments in 20th century philosophy of mind. Surely, now, “we would have to ascribe intentionality to the system” (1980a, p. 421). The computational model for consciousness stands to consciousness in the same way the computational model of anything stands to the domain being modelled. For the British video game development studio, see, Thought experiment on artifical intelligence by John Searle, Strong AI as computationalism or functionalism, Systems and virtual mind replies: finding the mind, Robot and semantics replies: finding the meaning, Commonsense knowledge / contextualist reply, Brain simulation and connectionist replies: redesigning the room, Many mansions / wait till next year reply, Speed and complexity: appeals to intuition, Searle writes that "according to Strong AI, the correct simulation really is a mind. . Searle also insists the systems reply would have the absurd consequence that “mind is everywhere.” For instance, “there is a level of description at which my stomach does information processing” there being “nothing to prevent [describers] from treating the input and output of my digestive organs as information if they so desire.” Besides, Searle contends, it’s just ridiculous to say “that while [the] person doesn’t understand Chinese, somehow the conjunction of that person and bits of paper might” (1980a, p. 420). This thesis of Ontological Subjectivity, as Searle calls it in more recent work, is not, he insists, some dualistic invocation of discredited “Cartesian apparatus” (Searle 1992, p. xii), as his critics charge; it simply reaffirms commonsensical intuitions that behavioristic views and their functionalistic progeny have, for too long, highhandedly, dismissed. [105] He noted that people never consider the problem of other minds when dealing with each other. I was invited to lecture at the Yale Artificial Intelligence Lab, and as I knew nothi… The whole point of the thought experiment is to put someone inside the room, where they can directly observe the operations of consciousness. [50], Searle has produced a more formal version of the argument of which the Chinese Room forms a part. Clearly, whether that inference is valid or not turns on a metaphysical question about the identity of persons and minds. Searle distinguishes between "intrinsic" intentionality and "derived" intentionality. The argument, to be clear, is not about whether a machine can be conscious, but about whether it (or anything else for that matter) can be shown to be conscious. He presented the first version in 1984. Since computers seem, on the face of things, to think, the conclusion that the essential nonidentity of thought with computation would seem to warrant is that whatever else thought essentially is, computers have this too; not, as Searle maintains, that computers’ seeming thought-like performances are bogus. "[24] John Haugeland wrote that "AI wants only the genuine article: machines with minds, in the full and literal sense. "[26], Searle's original presentation emphasized "understanding"—that is, mental states with what philosophers call "intentionality"—and did not directly address other closely related ideas such as "consciousness". Instead of imagining Searle working alone with his pad of paper and lookup table, like the Central Processing Unit of a serial architecture machine, the Churchlands invite us to imagine a more brainlike connectionist architecture. Though I am with the masquerade party, a full dress criticism is, perhaps, out of place here (see Hauser 1993 and Hauser 1997). The argument most commonly cited in opposition to the idea of the Turing test is a philosophical thought experiment put forth by John Searle in 1980: the Chinese room argument. Searle counters that this Connectionist Reply—incorporating, as it does, elements of both systems and brain-simulator replies—can, like these predecessors, be decisively defeated by appropriately tweaking the thought-experimental scenario. Both individually and collectively, nothing is being done in the Chinese gym except meaningless syntactic manipulations from which intentionality and consequently meaningful thought could not conceivably arise. neither does the system, because there isn’t anything in the system that isn’t in him. JOHN R. SEARLE'S CHINESE ROOM A case study in the philosophy of mind and cognitive science John R. Searle launched a remarkable discussion about the foundations of artificial intelligence and cognitive science in his well-known Chinese room argument in 1980 (Searle 1980). 1980b. It is chosen as an example and introduction to the philosophy of mind. [citation needed] In Season 4 of the American crime drama Numb3rs there is a brief reference to the Chinese room. The Chinese Room Argument can be refuted in one sentence: Searle confuses the mental qualities of one computational process, himself for example, with those of another process that the first process might be interpreting, a process that understands Chinese, for example. Imagine Searle-in-the-room, then, to be just one of very many agents, all working in parallel, each doing their own small bit of processing (like the many neurons of the brain). This, together with the premise – generally conceded by Functionalists – that programs might well be so implemented, yields the conclusion that computation, the “right programming” does not suffice for thought; the programming must be implemented in “the right stuff.” Searle concludes similarly that what the Chinese room experiment shows is that “[w]hat matters about brain operations is not the formal shadow cast by the sequences of synapses but rather the actual properties of the synapses” (1980, p. 422), their “specific biochemistry” (1980, p. 424). “All the same,” Searle maintains, “he understands nothing of the Chinese, and .
