Thus, Searle claims, Behaviorism and Functionalism are utterly refuted by this experiment; leaving dualistic and identity theoretic hypotheses in control of the field. The meaning of a symbol depends on how the symbols are related to each other when it comes to deduction. Critics of Searle's response argue that the program has allowed the man to have two minds in one head.[who?] 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. It is plain that any other method of probing the occupant of a Chinese room has the same difficulties in principle as exchanging questions and answers in Chinese. 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 … All of the replies that identify the mind in the room are versions of "the system reply". The Chinese experiment, then, can be seen to take aim at Behaviorism and Functionalism as a would-be counterexample to both. [g] He begins with an axiom that is intended to express the basic modern scientific consensus about brains and minds: Searle claims that we can derive "immediately" and "trivially" that: And from this he derives the further conclusions: Replies to Searle's argument may be classified according to what they claim to show:[o]. Searle contrasts strong AI with “weak AI.” According to weak AI, computers just simulate thought, their seeming understanding isn’t real understanding (just as-if), their seeming calculation is only as-if calculation, etc. Arguments of this form, according to Stevan Harnad, are "no refutation (but rather an affirmation)" of the Chinese room argument, because these arguments actually imply that no digital computers can have a mind. Or is the mind like the rainstorm, something other than a computer, and not realizable in full by a computer simulation? In short, executing an algorithm cannot be sufficient for thinking. The argument was first presented by philosopher John Searle in his paper, "Minds, Brains, and Programs", published in Behavioral and Brain Sciences in 1980. . “Computing Machinery and Intelligence.”. It is hard to visualize that an instant of one's conscious experience can be captured in a single large number, yet this is exactly what "strong AI" claims. Searle could receive Chinese characters through a slot in the door, process them according to the program's instructions, and produce Chinese characters as output. 1990. (3) Among those sympathetic to the Chinese room, it is mainly its negative claims – not Searle’s positive doctrine – that garner assent. Turing embodies this conversation criterion in a would-be experimental test of machine intelligence; in effect, a “blind” interview. It seemed to me that the Chinese room was now separated from me by two walls and windows. In fact, the room can just as easily be redesigned to weaken our intuitions. To call the Chinese room controversial would be an understatement. 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. It is a challenge to functionalism and the computational theory of mind,[g] and is related to such questions as the mind–body problem, the problem of other minds, the symbol-grounding problem, and the hard problem of consciousness.[a]. ", Larry Hauser writes that "biological naturalism is either confused (waffling between identity theory and dualism) or else it, The wording of each axiom and conclusion are from Searle's presentation in. (5) If Searle’s positive views are basically dualistic – as many believe – then the usual objections to dualism apply, other-minds troubles among them; so, the “other-minds” reply can hardly be said to “miss the point.” Indeed, since the question of whether computers (can) think just is an other-minds question, if other minds questions “miss the point” it’s hard to see how the Chinese room speaks to the issue of whether computers really (can) think at all. Since intuitions about the experiment seem irremediably at loggerheads, perhaps closer attention to the derivation could shed some light on vagaries of the argument (see Hauser 1997).  However, from Searle's perspective, this argument is circular. He writes "I thought the whole idea of strong AI was that we don't need to know how the brain works to know how the mind works.  In Season 4 of the American crime drama Numb3rs there is a brief reference to the Chinese room. Marcus Du Sautoy tries to find out using the Chinese Room Experiment. Searle's "strong AI" should not be confused with "strong AI" as defined by Ray Kurzweil and other futurists, who use the term to describe machine intelligence that rivals or exceeds human intelligence. 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. Searle distinguishes between "intrinsic" intentionality and "derived" intentionality. " If computation does not provide an explanation of the human mind, then strong AI has failed, according to Searle. The systems reply grants that “the individual who is locked in the room does not understand the story” but maintains that “he is merely part of a whole system, and the system does understand the story” (1980a, p. 419: my emphases). 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. ", 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". The Argument Of The Chinese Room ( CR ) 1122 Words | 5 Pages. Hew cited examples from the USS Vincennes incident.. This putative result, they contend, gets much if not all of its plausibility from the lack of neurophysiological verisimilitude in the thought-experimental setup. . Gottfried Leibniz made a similar argument in 1714 against mechanism (the position that the mind is a machine and nothing more). 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. ‘answers to the questions'”; “the set of rules in English . Clearly, whether that inference is valid or not turns on a metaphysical question about the identity of persons and minds. AI systems can be used to explain the mind; The study of the brain is irrelevant to the study of the mind; Mental states are computational states (which is why computers can have mental states and help to explain the mind); Since implementation is unimportant, the only empirical data that matters is how the system functions; hence the, Those which demonstrate how meaningless symbols can become meaningful, Those which suggest that the Chinese room should be redesigned in some way, Those which contend that Searle's argument is misleading, Those which argue that the argument makes false assumptions about subjective conscious experience and therefore proves nothing, John Preston and Mark Bishop, "Views into the Chinese Room", Oxford University Press, 2002. 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). [m] The only part of the argument which should be controversial is A3 and it is this point which the Chinese room thought experiment is intended to prove.[n]. Searle disagrees with this analysis and argues that "the study of the mind starts with such facts as that humans have beliefs, while thermostats, telephones, and adding machines don't ... what we wanted to know is what distinguishes the mind from thermostats and livers. The thrust of the argument is that it couldn’t be just computational processes and their output because the computational processes and their output can exist without the cognitive state” (1980a, p. 420-421: my emphases). . 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. " He takes it as obvious that we can detect the presence of consciousness and dismisses these replies as being off the point. Since they can't detect causal properties, they can't detect the existence of the mental. They argue that Searle must be mistaken about the "knowability of the mental", and in his belief that there are "causal properties" in our neurons that give rise to the mind. 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. I was invited to lecture at the Yale Artificial Intelligence Lab, and as I knew nothi… These arguments, if accepted, prevent Searle from claiming that his conclusion is obvious by undermining the intuitions that his certainty requires. The focus belongs on the program's Turing machine rather than on the person's. Searle imagines himself sealed in a room with a slit for questions in Chinese to be submitted on paper. Some replies to Searle begin by arguing that the room, as described, cannot have a Chinese-speaking mind.  Leibniz found it difficult to imagine that a "mind" capable of "perception" could be constructed using only mechanical processes. In his essay Can Computers Think?, Searle gives his own definition of strong artificial intelligence, which he subsequently tries to refute. Several critics believe that Searle's argument relies entirely on intuitions.  It is also a central theme in the video game Virtue's Last Reward, and ties into the game's narrative. Nagel, Thomas. 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. . Whatever meaning Searle-in-the-room’s computation might derive from the meaning of the Chinese symbols which he processes will not be intrinsic to the process or the processor but “observer relative,” existing only in the minds of beholders such as the native Chinese speakers outside the room. He doesn't intend to solve the problem of other minds (for machines or people) and he doesn't think we need to. Then the whole system consists of just one object: the man himself.  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. 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). . they call ‘the program'”: you yourself know none of this. the "mind that speaks Chinese" could be such things as: the "software", a "program", a "running program", a simulation of the "neural correlates of consciousness", the "functional system", a "simulated mind", an "emergent property", or "a virtual mind" (Marvin Minsky's version of the systems reply, described below). The Connectionist Reply (as it might be called) is set forth—along with a recapitulation of the Chinese room argument and a rejoinder by Searle—by Paul and Patricia Churchland in a 1990 Scientific American piece. Since Searle-in-the-room, in this revised scenario, does only a very small portion of the total computational job of generating sensible Chinese replies in response to Chinese input, naturally he himself does not comprehend the whole process; so we should hardly expect him to grasp or to be conscious of the meanings of the communications he is involved, in such a minor way, in processing. 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. If the person understanding is not identical with the room operator, then the inference is unsound.". The computer manipulates the symbols using a form of syntax rules, without any knowledge of the symbol's semantics (that is, their meaning). 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. It’s intuitively utterly obvious, Searle maintains, that no one and nothing in the revised “Chinese gym” experiment understands a word of Chinese either individually or collectively. The computational model for consciousness stands to consciousness in the same way the computational model of anything stands to the domain being modelled. of the system” by memorizing the rules and script and doing the lookups and other operations in their head. 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..
