Consciousness Thought ExperimentsQuestion 1 of 20

The 'Robot Reply' to the Chinese Room suggests that if the symbol-processing system were placed in a robot that could interact with the world—seeing objects, navigating, etc.—it would acquire genuine understanding. Searle counters that this addition does not solve the fundamental problem. Why?

Because building a robot with such sophisticated sensors and motors is a practical impossibility that makes the reply irrelevant.
Because the robot's sensor data would simply be more formal symbols for the person in the room to manipulate according to rules, adding no semantic content.
Because the robot's behavior, while more complex, would still be rigid and formulaic, eventually revealing its lack of genuine intelligence.
Because true understanding requires social and emotional interaction, not just physical interaction with inanimate objects.

All questions

Question 1

The 'Robot Reply' to the Chinese Room suggests that if the symbol-processing system were placed in a robot that could interact with the world—seeing objects, navigating, etc.—it would acquire genuine understanding. Searle counters that this addition does not solve the fundamental problem. Why?

  1. Because building a robot with such sophisticated sensors and motors is a practical impossibility that makes the reply irrelevant.
  2. Because the robot's sensor data would simply be more formal symbols for the person in the room to manipulate according to rules, adding no semantic content. (correct answer)
  3. Because the robot's behavior, while more complex, would still be rigid and formulaic, eventually revealing its lack of genuine intelligence.
  4. Because true understanding requires social and emotional interaction, not just physical interaction with inanimate objects.
Explanation: The correct answer is B. Searle's response to the Robot Reply is that adding perceptual and motor capacities doesn't bridge the gap between syntax and semantics. He argues that the input from the robot's camera would just be another stream of symbols (e.g., '101101' for 'see hamburger'), and the output to its motors would be another set of symbols. The person inside is still just shuffling symbols according to a rulebook and never attaches meaning to them. (A) is a practical, not philosophical, objection. (C) contradicts the premise of the reply, which assumes the robot behaves appropriately. (D) is a plausible point, but (B) represents Searle's more fundamental objection.

Question 2

In Frank Jackson's thought experiment, the brilliant neuroscientist Mary knows all the physical facts about color vision but has never seen color. According to Jackson's original argument, what specific type of knowledge does Mary gain when she sees a red tomato for the first time?

  1. A new set of physical facts about how her own brain processes the new sensory information, which were previously inaccessible to her.
  2. A new ability or 'know-how,' specifically the skill of recognizing and imagining the color red, which is distinct from factual knowledge.
  3. Knowledge of a non-physical fact concerning the phenomenal quality, or 'qualia,' of the subjective experience of seeing red. (correct answer)
  4. A more complete conceptual understanding of 'redness,' allowing her to refine her existing scientific theories of color perception.
Explanation: The correct answer is C. The entire point of the Knowledge Argument is that Mary learns what it is like to see red. This is knowledge of qualia, the subjective character of experience. Jackson argues that since she already knew all the physical facts, this new knowledge must be of a non-physical fact. (A) is a physicalist counter-argument, suggesting the new fact is still physical. (B) describes the 'Ability Hypothesis,' a major objection to Jackson's conclusion, not the conclusion itself. (D) is incorrect because the argument stipulates her prior scientific knowledge was already complete.

Question 3

The 'Ability Hypothesis' is a major physicalist objection to the Knowledge Argument. It argues that when Mary sees red, she doesn't learn a new fact (or gain propositional knowledge), but rather acquires a new ability. Which of the following best exemplifies the kind of ability that proponents of this hypothesis claim Mary gains?

  1. The ability to write down the complete physical equations governing the perception of red.
  2. The ability to recognize red objects by sight, to imagine redness, and to remember what seeing red was like. (correct answer)
  3. The ability to deduce new, previously unknown, physical laws about the universe from her experience.
  4. The ability to persuade other philosophers that her experience demonstrates the truth of property dualism.
Explanation: The correct answer is B. The Ability Hypothesis, most famously defended by David Lewis, posits that Mary gains 'know-how,' not 'know-that.' The abilities to recognize, imagine, and remember are practical skills related to the experience, which are different from learning a new fact or proposition. (A) is propositional knowledge she already possessed. (C) is unlikely and not what the hypothesis claims. (D) is about her ability to argue, not the specific cognitive ability she gains from the experience itself.

Question 4

Suppose that upon seeing red for the first time, Mary calmly says, 'Interesting. The phenomenal quality is precisely as my complete physical knowledge led me to expect.' If this were Mary's genuine reaction, what would it demonstrate about the Knowledge Argument?

  1. It would prove the argument correct, as her statement refers to a 'phenomenal quality' which is a non-physical property.
  2. It would refute the argument by showing that complete physical knowledge is sufficient to know what an experience is like. (correct answer)
  3. It would be irrelevant to the argument, as the argument is about what she learns, not about whether she is surprised.
  4. It would support the 'Ability Hypothesis' by showing she had factual knowledge but lacked the ability to confirm it.
Explanation: The correct answer is B. The entire force of the Knowledge Argument comes from the intuition that Mary would be surprised and learn something new. If she is not surprised and learns nothing new, it means that her complete physical knowledge was, in fact, sufficient for her to know everything there is to know about the experience of seeing red, including what it's like. This would falsify the argument's key premise and support the physicalist position. (A) misinterprets her statement; she is claiming her physical knowledge already encompassed this quality. (C) is incorrect; the intuition of surprise is central to making the argument compelling. (D) is not directly supported; her reaction speaks to her propositional knowledge being sufficient, undermining the need for a separate category of knowledge.

Question 5

Consider a variation of the Chinese Room where the static rulebook is replaced by a dynamic, self-modifying neural network. This network was trained on a vast corpus of Chinese texts and conversations, and it can generate nuanced, context-aware, and even emotionally resonant replies. The person in the room now simply provides the input symbols to the network and relays its output.

From John Searle's perspective, how would this modification affect the central conclusion of his thought experiment?

  1. It would neutralize the argument, as a sophisticated neural network is not merely manipulating symbols but processing information in a brain-like way.
  2. It would significantly strengthen the argument, as it shows that even with learning and complexity, the system can still operate without any genuine understanding. (correct answer)
  3. It would make the argument irrelevant, because Searle's critique was aimed at symbolic, rule-based AI, not modern connectionist models.
  4. It would shift the argument's focus from understanding language to understanding emotions, which Searle believes machines can never possess.
Explanation: The correct answer is B. Searle has explicitly stated that his argument applies to any computational system, including connectionist ones like neural networks. From his perspective, the neural network is just a more complex, opaque 'rulebook.' The person in the room (or the system as a whole) is still just implementing a program (the trained network) and manipulating inputs to produce outputs without any semantic grasp of the content. Therefore, this modification simply presents a more sophisticated version of a syntax-manipulating engine that still lacks semantics, reinforcing his original point. (A) is the view Searle is arguing against. (C) is a common misunderstanding; Searle does not believe connectionism solves the problem. (D) narrows the focus incorrectly; Searle's point is about all understanding, not just emotions.

Question 6

Despite their different scenarios, Searle's Chinese Room and Jackson's Mary's Room share a similar argumentative strategy and philosophical goal. What is the most accurate description of this shared purpose?

  1. To provide a positive argument for the existence of an immaterial soul that is the seat of consciousness and understanding.
  2. To demonstrate that certain essential features of the mind, such as understanding or phenomenal experience, cannot be fully captured by a third-person, functional, or physical account. (correct answer)
  3. To prove that human intelligence is unique in the universe and that creating any form of artificial consciousness is a logical impossibility.
  4. To argue that the methods of analytic philosophy are superior to the methods of empirical science for investigating the nature of the mind.
Explanation: The correct answer is B. Both are 'intuition pump' arguments designed to show that a certain type of third-person, objective story about the mind is missing something essential. Searle argues that a functional/computational account (which looks only at inputs, outputs, and program states) misses semantic understanding. Jackson argues that a complete physical account misses first-person phenomenal experience (qualia). They are both negative arguments aimed at showing the insufficiency of a dominant materialist/functionalist view of the mind. (A) is too strong; while their conclusions are friendly to dualism, they don't explicitly argue for a soul. (C) is also too strong; they argue against certain approaches to AI/mind, not that it's impossible in principle. (D) is a methodological claim, whereas the arguments are metaphysical and epistemological claims about the mind itself.

Question 7

A musicologist is born completely deaf but becomes the world's leading expert on the physics of sound and the neuroscience of auditory perception. She knows every objective fact about how Beethoven's 5th Symphony is encoded in a sound wave and processed by the human brain. She then receives a cochlear implant and hears the symphony for the first time. The Knowledge Argument would claim this experience most significantly provides her with:

  1. a deeper, more nuanced understanding of the symphony's complex musical structure and composition.
  2. conclusive evidence that her prior scientific knowledge of acoustics and neuroscience was somehow incomplete or inaccurate.
  3. a new ability to recognize the symphony from its sound, which is a form of procedural knowledge or know-how.
  4. new knowledge of what it is like to phenomenally experience the music, a fact not captured by the physical information alone. (correct answer)
Explanation: The correct answer is D. This is a direct auditory analogy to Mary's visual experience. The Knowledge Argument's conclusion is that there is a class of non-physical facts related to 'what it's like' to have an experience (qualia). The musicologist, like Mary, had all the physical facts but lacked this phenomenal knowledge until she had the experience. (A) is unlikely, as she could study the score and structure exhaustively without hearing. (B) contradicts the premise that her prior knowledge was complete. (C) describes the Ability Hypothesis, which is an objection to the argument's conclusion, not the conclusion itself.

Question 8

A prominent objection to the Chinese Room argument is the 'Systems Reply,' which posits that while the person in the room does not understand Chinese, the entire system (the person, the rulebook, the room, etc.) as a whole does. How does Searle attempt to refute this specific reply?

  1. By arguing that the system as a whole still lacks the specific causal powers of a biological brain required for genuine intentionality.
  2. By pointing out that the system's outputs, however convincing, would eventually be exposed as lacking understanding with sufficiently complex questions.
  3. By proposing that the person internalizes the entire system—memorizing the rules and doing the computations in their head—and yet still fails to understand Chinese. (correct answer)
  4. By claiming that understanding is an irreducibly first-person phenomenon, and a 'system' cannot be the subject of such a phenomenon.
Explanation: The correct answer is C. Searle's famous counter to the Systems Reply is to have the individual internalize all the components of the system. He asks us to imagine the person memorizes the rules and the symbol batches and does all the work in their head while standing in an open field. Searle's intuition is that this person—who is now the entire system—still doesn't understand a word of Chinese, thus showing that the system itself does not understand. (A) is related to his reply to the Brain Simulator argument. (B) is incorrect as Searle grants the system passes the Turing Test. (D) is a related intuition but (C) describes the specific argumentative move he makes against the Systems Reply.

Question 9

An advanced android, 'Unit 734,' is programmed with the complete chemical and physical knowledge of taste. It can analyze any food item, provide a perfect breakdown of its molecular components, predict how human taste receptors will respond, and even write poetry about eating a strawberry that a human would find authentic. However, Unit 734 itself has no taste receptors and cannot eat.

Based on the passage, an advocate of the logic used in Mary's Room would most likely argue that:

  1. Unit 734 genuinely understands taste because it can replicate the behavioral and linguistic outputs associated with it.
  2. if Unit 734 were given taste receptors, it would learn nothing new, since it already possesses all the propositional knowledge about taste.
  3. Unit 734's inability to taste is a hardware limitation that is irrelevant to the philosophical question of machine consciousness.
  4. Unit 734 lacks the phenomenal experience of what it is like to taste a strawberry, a form of knowledge it cannot acquire from its physical data alone. (correct answer)
Explanation: The correct answer is D. This scenario is a direct analogy to Mary's Room, but with taste instead of sight. A proponent of the Knowledge Argument would claim that just as Mary lacks knowledge of what it's like to see red, Unit 734 lacks knowledge of what it's like to taste a strawberry. This phenomenal knowledge, the argument goes, is a non-physical fact not contained in its complete physical database. (A) represents the functionalist view that the argument opposes. (B) represents the physicalist view that the argument opposes. (C) misses the philosophical point by dismissing the scenario as a mere technical problem; the argument's advocate uses this exact limitation to make their point.

Question 10

Imagine Mary, after leaving her black-and-white room and experiencing color, is then placed inside Searle's Chinese Room. She is given the task of answering questions about the color red, using a rulebook that maps Chinese symbols for questions about red to Chinese symbols for answers. Based on the fundamental premises of both thought experiments, which conclusion is the most philosophically sound?

  1. Mary's direct experience of red (a semantic understanding) highlights the purely syntactic nature of her work inside the Chinese Room. (correct answer)
  2. The combination of Mary's phenomenal knowledge and the room's rulebook would be sufficient for the system as a whole to genuinely understand Chinese.
  3. Because Mary now truly understands 'red,' she would be able to answer questions in Chinese about red without needing to use the rulebook.
  4. The fact that Mary can experience red proves that the human brain has causal powers that the Chinese Room's rulebook could never simulate.
Explanation: The correct answer is A. This question requires synthesizing the two arguments. Mary now possesses the phenomenal, subjective knowledge of 'what it's like' to see red—a form of semantic understanding, according to Jackson. Inside the room, she is merely manipulating symbols for 'red' according to rules, a purely syntactic task. The juxtaposition makes Searle's point even sharper: she has the relevant semantics but is engaged in a task that completely lacks it. (B) is what the Systems Reply might claim, but it runs counter to the spirit of both arguments. (C) is incorrect; her knowledge of red does not magically grant her knowledge of the Chinese language. (D) states a premise from Searle's later arguments (the 'causal powers of the brain'), but (A) is a more direct and accurate conclusion drawn from combining the two initial scenarios.

Question 11

One of the most powerful physicalist replies to Mary's Room argues that Mary does not learn a new fact, but rather comes to know an old fact in a new way. This is sometimes called the 'New Knowledge/Old Fact' view. Which of the following scenarios provides the best analogy for this type of epistemic change?

  1. A historian studies a battle from documents and then discovers a new diary that reveals a previously unknown, decisive event.
  2. A physicist knows that H₂O is water and then learns through a new experiment that H₂O has a previously undiscovered chemical property.
  3. A person knows that Mark Twain wrote Huckleberry Finn, and then learns that Samuel Clemens also wrote Huckleberry Finn, without realizing they are the same person.
  4. A tourist knows on a map that Metropolis is north of Gotham, and then learns this same fact by standing on a hill and seeing Gotham to the south. (correct answer)
Explanation: The correct answer is D. This analogy perfectly captures the 'New Knowledge/Old Fact' idea. The tourist knew the proposition 'Metropolis is north of Gotham' from the map (like Mary knowing about red from textbooks). By seeing it for themselves, they gain a new, perspectival way of knowing that same fact, but they don't learn a new fact about the world's geography. This is what the physicalist claims happens to Mary: she gains a first-person way of knowing a physical fact she already knew in a third-person way. (A) and (B) describe learning genuinely new facts. (C) is about identity, which is a slightly different issue (the Frege-style puzzle of identity statements) and a less direct analogy than (D).

Question 12

The 'Brain Simulator Reply' to the Chinese Room posits a computer that simulates the exact neural firings of a native Chinese speaker's brain. The reply claims this system would understand Chinese. Searle's primary counter-argument rests on the claim that:

  1. a simulation of a brain's neural activity is computationally distinct from the brain's actual activity and would produce different behaviors.
  2. the simulation of a thing is not the thing itself; a simulated fire doesn't burn you, and a simulated brain lacks the brain's essential causal powers. (correct answer)
  3. such a detailed simulation is technologically unfeasible and therefore the thought experiment is not a meaningful objection.
  4. the man in the room could not perform this simulation by hand, which proves the system could not be conscious.
Explanation: The correct answer is B. This is the core of Searle's response. He argues that what matters for consciousness and intentionality are the actual physical, causal properties of the brain's 'wetware.' A computer simulation, no matter how detailed, is just a model of these properties, not a duplication of them. He famously uses the analogy of a computer simulation of a rainstorm—it can model the storm perfectly, but it won't make anything wet. Likewise, a simulated brain won't have real understanding. (A) is not his point; he grants the behavior might be identical. (C) is a practical objection, not his philosophical one. (D) misrepresents his counter, which involves reimagining the simulation with non-computational elements (like water pipes) to show the logic still holds.

Question 13

A central claim of John Searle's Chinese Room argument is that a system can successfully process inputs and generate appropriate outputs according to a formal set of rules, yet lack any genuine understanding of the content. This argument is primarily intended to highlight a fundamental gap between:

  1. algorithmic procedures and their corresponding behavioral outputs, suggesting that behavior is an unreliable guide to mental states.
  2. syntactic manipulation and semantic content, suggesting that following rules for symbols is insufficient for grasping their meaning. (correct answer)
  3. first-person subjective experience and third-person objective knowledge, suggesting that consciousness cannot be fully described by science.
  4. the complexity of a computational program and the speed of its physical execution, suggesting practical limits on creating artificial intelligence.
Explanation: The correct answer is B. Searle's core point is that the person in the room is manipulating symbols based only on their formal properties (syntax) without any understanding of what they mean (semantics). The argument concludes that syntax is not sufficient for semantics. (A) is incorrect because the room successfully links procedures to outputs; Searle's point is that this linkage isn't enough for understanding. (C) describes the gap highlighted by Mary's Room, not the Chinese Room. (D) is a practical engineering concern, not the philosophical distinction Searle is making.

Question 14

The 'Ability Hypothesis' is a major physicalist objection to the Knowledge Argument. It argues that when Mary sees red, she doesn't learn a new fact (or gain propositional knowledge), but rather acquires a new ability. Which of the following best exemplifies the kind of ability that proponents of this hypothesis claim Mary gains?

  1. The ability to write down the complete physical equations governing the perception of red.
  2. The ability to recognize red objects by sight, to imagine redness, and to remember what seeing red was like. (correct answer)
  3. The ability to deduce new, previously unknown, physical laws about the universe from her experience.
  4. The ability to persuade other philosophers that her experience demonstrates the truth of property dualism.
Explanation: The correct answer is B. The Ability Hypothesis, most famously defended by David Lewis, posits that Mary gains 'know-how,' not 'know-that.' The abilities to recognize, imagine, and remember are practical skills related to the experience, which are different from learning a new fact or proposition. (A) is propositional knowledge she already possessed. (C) is unlikely and not what the hypothesis claims. (D) is about her ability to argue, not the specific cognitive ability she gains from the experience itself.

Question 15

Consider a variation of the Chinese Room where the static rulebook is replaced by a dynamic, self-modifying neural network. This network was trained on a vast corpus of Chinese texts and conversations, and it can generate nuanced, context-aware, and even emotionally resonant replies. The person in the room now simply provides the input symbols to the network and relays its output.

From John Searle's perspective, how would this modification affect the central conclusion of his thought experiment?

  1. It would neutralize the argument, as a sophisticated neural network is not merely manipulating symbols but processing information in a brain-like way.
  2. It would significantly strengthen the argument, as it shows that even with learning and complexity, the system can still operate without any genuine understanding. (correct answer)
  3. It would make the argument irrelevant, because Searle's critique was aimed at symbolic, rule-based AI, not modern connectionist models.
  4. It would shift the argument's focus from understanding language to understanding emotions, which Searle believes machines can never possess.
Explanation: The correct answer is B. Searle has explicitly stated that his argument applies to any computational system, including connectionist ones like neural networks. From his perspective, the neural network is just a more complex, opaque 'rulebook.' The person in the room (or the system as a whole) is still just implementing a program (the trained network) and manipulating inputs to produce outputs without any semantic grasp of the content. Therefore, this modification simply presents a more sophisticated version of a syntax-manipulating engine that still lacks semantics, reinforcing his original point. (A) is the view Searle is arguing against. (C) is a common misunderstanding; Searle does not believe connectionism solves the problem. (D) narrows the focus incorrectly; Searle's point is about all understanding, not just emotions.

Question 16

A musicologist is born completely deaf but becomes the world's leading expert on the physics of sound and the neuroscience of auditory perception. She knows every objective fact about how Beethoven's 5th Symphony is encoded in a sound wave and processed by the human brain. She then receives a cochlear implant and hears the symphony for the first time. The Knowledge Argument would claim this experience most significantly provides her with:

  1. a deeper, more nuanced understanding of the symphony's complex musical structure and composition.
  2. conclusive evidence that her prior scientific knowledge of acoustics and neuroscience was somehow incomplete or inaccurate.
  3. a new ability to recognize the symphony from its sound, which is a form of procedural knowledge or know-how.
  4. new knowledge of what it is like to phenomenally experience the music, a fact not captured by the physical information alone. (correct answer)
Explanation: The correct answer is D. This is a direct auditory analogy to Mary's visual experience. The Knowledge Argument's conclusion is that there is a class of non-physical facts related to 'what it's like' to have an experience (qualia). The musicologist, like Mary, had all the physical facts but lacked this phenomenal knowledge until she had the experience. (A) is unlikely, as she could study the score and structure exhaustively without hearing. (B) contradicts the premise that her prior knowledge was complete. (C) describes the Ability Hypothesis, which is an objection to the argument's conclusion, not the conclusion itself.

The 'Brain Simulator Reply' to the Chinese Room posits a computer that simulates the exact neural firings of a native Chinese speaker's brain. The reply claims this system would understand Chinese. Searle's primary counter-argument rests on the claim that:

  1. a simulation of a brain's neural activity is computationally distinct from the brain's actual activity and would produce different behaviors.
  2. the simulation of a thing is not the thing itself; a simulated fire doesn't burn you, and a simulated brain lacks the brain's essential causal powers. (correct answer)
  3. such a detailed simulation is technologically unfeasible and therefore the thought experiment is not a meaningful objection.
  4. the man in the room could not perform this simulation by hand, which proves the system could not be conscious.
Explanation: The correct answer is B. This is the core of Searle's response.

(D) misrepresents his counter, which involves reimagining the simulation with non-computational elements (like water pipes) to show the logic still holds.

Question 18

Despite their different scenarios, Searle's Chinese Room and Jackson's Mary's Room share a similar argumentative strategy and philosophical goal. What is the most accurate description of this shared purpose?

  1. To provide a positive argument for the existence of an immaterial soul that is the seat of consciousness and understanding.
  2. To demonstrate that certain essential features of the mind, such as understanding or phenomenal experience, cannot be fully captured by a third-person, functional, or physical account. (correct answer)
  3. To prove that human intelligence is unique in the universe and that creating any form of artificial consciousness is a logical impossibility.
  4. To argue that the methods of analytic philosophy are superior to the methods of empirical science for investigating the nature of the mind.
Explanation: The correct answer is B. Both are 'intuition pump' arguments designed to show that a certain type of third-person, objective story about the mind is missing something essential. Searle argues that a functional/computational account (which looks only at inputs, outputs, and program states) misses semantic understanding. Jackson argues that a complete physical account misses first-person phenomenal experience (qualia). They are both negative arguments aimed at showing the insufficiency of a dominant materialist/functionalist view of the mind. (A) is too strong; while their conclusions are friendly to dualism, they don't explicitly argue for a soul. (C) is also too strong; they argue against certain approaches to AI/mind, not that it's impossible in principle. (D) is a methodological claim, whereas the arguments are metaphysical and epistemological claims about the mind itself.

Question 19

Frank Jackson, who originally proposed the Knowledge Argument, later recanted his conclusion. He came to accept physicalism, arguing that his original thought experiment was misleading. His new position suggested that Mary's experience gives her new representational content about her own brain states, which are physical states. This change of mind illustrates that...

  1. the initial intuitions elicited by a thought experiment are not always conclusive and can be reinterpreted. (correct answer)
  2. the concept of qualia has been scientifically proven to be an illusion, forcing philosophers to abandon the idea.
  3. the Chinese Room argument is a more robust and successful argument against materialism than Mary's Room.
  4. philosophical arguments are purely subjective and have no bearing on objective truths about the world.
Explanation: The correct answer is A. The fact that the argument's own author later rejected it highlights a key feature of philosophical thought experiments: their reliance on intuition. Jackson's change of mind shows that the initial, powerful intuition that Mary learns something non-physical can be challenged, re-analyzed, and ultimately rejected in favor of a more complex physicalist explanation. It demonstrates the ongoing, dialectical nature of philosophical inquiry. (B) is false; there is no such scientific proof. (C) is a comparative judgment that isn't directly supported by Jackson's personal intellectual journey. (D) is an overly strong and cynical conclusion; Jackson changed his mind based on what he saw as better arguments, not pure subjectivity.

Question 20

John Searle distinguishes between 'Strong AI' and 'Weak AI.' His Chinese Room argument is aimed exclusively at refuting the claims of Strong AI. Which of the following research projects best exemplifies Weak AI, and would therefore be conceptually unaffected by Searle's argument?

  1. Developing a computational system that is intended to possess genuine self-awareness and subjective consciousness.
  2. Creating a powerful supercomputer to simulate weather patterns to test hypotheses about climate change. (correct answer)
  3. Building an android that not only acts human but is claimed to have the same mental states of understanding and belief.
  4. Programming a machine based on a model of the human brain with the goal of duplicating human intentionality.
Explanation: The correct answer is B. Weak AI is the view that computers can be used as powerful tools to simulate mental processes and study the mind, without the machine itself having a mind. A weather simulation is a perfect example of using computation as a tool to model a complex system. (A), (C), and (D) are all descriptions of the project of Strong AI, which claims that a properly programmed computer can have a mind, consciousness, and understanding. These are the direct targets of Searle's argument.
