Chapter 23 Quiz: Philosophy of Mind
Part I: Multiple Choice
Select the best answer for each question.
1. René Descartes' view that the mind and body are two fundamentally different kinds of substance is called:
- A) Functionalism
- B) Type identity theory
- C) Substance dualism
- D) Eliminative materialism
Answer: C — Descartes held that the mind (res cogitans, thinking substance) and body (res extensa, extended substance) are two fundamentally different kinds of substance. This is the defining claim of Cartesian substance dualism.
2. The "interaction problem" for Cartesian dualism is:
- A) The problem of explaining how we know other minds exist
- B) The problem of explaining how a non-physical mind can causally interact with a physical body
- C) The difficulty of integrating phenomenology with neuroscience
- D) The challenge of explaining how multiple mental states can interact with each other
Answer: B — If mind and body are fundamentally different kinds of substance (one non-physical, one physical), it is deeply puzzling how they could causally affect each other. How does a non-physical decision cause a physical arm to move?
3. Functionalism holds that mental states are:
- A) Identical to specific brain states (e.g., pain = C-fiber firing)
- B) Defined by their causal/functional role — their relations to inputs, outputs, and other mental states
- C) Illusions that will eventually be eliminated by neuroscience
- D) Constituted entirely by embodied, pre-reflective engagement with the world
Answer: B — Functionalism defines mental states by their functional role, not their physical substrate. What makes something pain is what it does (caused by tissue damage, causes avoidance behavior, etc.), not what it is made of.
4. The "multiple realizability" objection to type identity theory argues that:
- A) Consciousness cannot be reduced to information processing
- B) Different people can have identical brain states with different subjective experiences
- C) The same mental state type (e.g., pain) can be realized in different physical substrates, so mental states cannot be identical to specific physical types
- D) Multiple competing theories of consciousness are all partially correct
Answer: C — Hilary Putnam argued that pain can be "realized" in organisms with very different neuroanatomy, and perhaps in silicon systems. If so, pain cannot be identical to any single physical type (like C-fiber firing), since pain could exist without C-fibers.
5. Paul and Patricia Churchland's view that folk-psychological concepts (belief, desire, etc.) will eventually be replaced by neuroscientific description is called:
- A) Higher-order theory
- B) Phenomenology
- C) Eliminative materialism
- D) Panpsychism
Answer: C — The Churchlands argue that folk psychology is a radically flawed theoretical framework, analogous to phlogiston theory in chemistry, and that a mature neuroscience will not supplement but eliminate its vocabulary.
6. David Chalmers distinguishes "easy problems" from the "hard problem" of consciousness. Which of the following is an example of an "easy problem" in Chalmers' sense?
- A) Why does neural activity give rise to subjective experience at all?
- B) Why does there seem to be something it is like to see red?
- C) Explaining how the brain integrates information from different sensory sources
- D) Why are philosophical zombies conceivable?
Answer: C — The "easy problems" (not genuinely easy, but tractable in principle) are about explaining cognitive functions and mechanisms. Explaining information integration is a functional question; it can, in principle, be answered by explaining the mechanism. The "hard problem" asks why any of this produces experience at all.
7. Chalmers' "philosophical zombie argument" is best summarized as:
- A) If we can conceive of beings physically identical to us but lacking conscious experience, this suggests consciousness is not logically entailed by physical facts
- B) Because we can simulate consciousness computationally, consciousness must be reducible to computation
- C) Consciousness is irreducible because no machine can pass the Turing Test for inner experience
- D) Zombies in popular culture illustrate the difficulty of identifying genuine consciousness
Answer: A — If a world with philosophical zombies (beings physically/functionally identical to us but with no inner experience) is genuinely conceivable, then consciousness is not entailed by physical description — which suggests physicalism cannot fully account for consciousness.
8. Frank Jackson's Mary's Room thought experiment is designed to support which conclusion?
- A) Functional organization is sufficient for consciousness
- B) The brain processes visual information through a unified global workspace
- C) There are facts about phenomenal experience that are not captured by physical facts
- D) Memory is required for genuine consciousness
Answer: C — If Mary, who knows all physical facts about color vision, still learns something new when she sees red for the first time, then that new knowledge must be a non-physical fact about phenomenal experience.
9. John Searle's Chinese Room argument concludes that:
- A) Syntax (symbol manipulation) is not sufficient for semantics (genuine understanding or consciousness)
- B) Chinese is too complex a language for any computer to process
- C) The Turing Test is the best criterion for machine consciousness
- D) Functionalism is correct, but only for biological systems
Answer: A — Searle's argument is that following formal rules for manipulating symbols — which is what any computer program does — cannot produce genuine understanding or meaning. The room appears to understand Chinese, but no actual understanding is present. Syntax alone doesn't produce semantics.
10. Which of the following best characterizes Maurice Merleau-Ponty's contribution to philosophy of mind?
- A) He argued that consciousness can be fully explained by computational processes
- B) He insisted that consciousness is fundamentally embodied — shaped by our bodily engagement with the world — not a disembodied processing system
- C) He developed the concept of qualia as non-physical properties of experience
- D) He argued that the mind and body are identical in substance but differ in description
Answer: B — Merleau-Ponty argued, against the Cartesian tradition, that consciousness is not a mind enclosed in a body but is constituted by embodied, pre-reflective engagement with the world. The body schema, motor intentionality, and bodily being-in-the-world are central to his account.
Part II: Short Answer
Answer each question in 3–5 sentences. Focus on precision and clarity.
11. What is intentionality, and why does it matter for philosophy of mind?
Model answer: Intentionality is the "aboutness" or directedness of mental states — the fact that consciousness is always consciousness of something. When I perceive, I perceive something; when I believe, I believe that something is the case. Husserl identified intentionality as the fundamental structure of conscious experience. It matters because it distinguishes genuine mental states from mere causal responses: a thermostat responds to temperature, but a belief is about temperature in a way that involves genuine reference and representation. Whether intentionality can be reduced to functional or physical terms is one of the central debates in philosophy of mind.
12. Explain the difference between Chalmers' "easy problems" and the "hard problem" of consciousness. Why does Chalmers insist they are different in kind, not just in difficulty?
Model answer: The "easy problems" concern cognitive functions and mechanisms: explaining how the brain integrates information, controls behavior, or reports on its own states. These are "easy" in the sense that we can, in principle, address them by discovering the relevant mechanisms — even if the science is hard. The "hard problem" is why any of this cognitive activity involves subjective experience at all — why there is something it is like to see red, feel pain, or hear music, rather than all the processing happening without any felt quality. Chalmers insists the problems are different in kind because even a complete functional/mechanistic explanation of all the easy problems would leave unanswered the question of why there is experience; the explanatory gap persists even after full functional explanation. The hard problem is not about which mechanism produces experience; it is about why any mechanism produces experience rather than none.
13. What is the "systems reply" to Searle's Chinese Room, and how does Searle respond to it?
Model answer: The systems reply holds that even though the person inside the room does not understand Chinese, the whole system — person, rules, stored symbols — does. Understanding is a property of the system, not of any single component, just as a single neuron does not understand anything while the brain as a whole does. Searle responds by asking us to imagine the person memorizing all the rules and stored symbols, so that she internalizes the entire system and performs all computations mentally, without any external props. The person is now the whole system — yet she still does not understand Chinese. Understanding has not appeared anywhere in the system, despite the system being present in its entirety. Searle takes this to show that the systems reply fails: understanding is not a property of systems of the right functional complexity, but requires something additional.
14. What are qualia, and why do they pose a problem for physicalism?
Model answer: Qualia are the intrinsic, subjective, qualitative properties of experience — the "redness" of red as you experience it, the painfulness of pain, the specific flavor of coffee. They are what give experience its particular phenomenal character. They pose a problem for physicalism because it is difficult to see how physical or functional descriptions could capture these qualitative properties. Frank Jackson's Mary's Room argument makes this vivid: even knowing every physical fact about color vision, Mary does not know what it is like to see red until she has the experience. If her new knowledge is genuine (as it seems to be), then phenomenal facts are not physical facts — which is a serious problem for any view that holds all facts are ultimately physical.
15. How does Merleau-Ponty's conception of the "body schema" challenge the traditional Cartesian picture of the mind?
Model answer: For Descartes, the mind is a thinking, non-physical substance that relates to the body as a kind of operator to a machine — the mind is "in" the body but is not fundamentally shaped by it. Merleau-Ponty argues this picture is fundamentally wrong. The body schema is the body's pre-reflective, practical understanding of its own position, capabilities, and spatial relations — the bodily intelligence that allows a musician's fingers to find the right notes without deliberate calculation, or allows us to navigate a familiar room in the dark. This bodily understanding is not a product of conscious deliberation by a mind "inside" the body; it is a form of understanding, a form of intentionality, that exists at the level of the body. For Merleau-Ponty, the Cartesian picture generates artificial puzzles (how does mind get back in touch with the body it was never separated from?) by beginning from a mistaken separation of mind and body.
