All questions

Question 1

A primatologist presents evidence that bonobos exhibit empathy, tool use, and complex social problem-solving. She argues for their inclusion in the 'community of persons.' This argument most directly challenges a conception of personhood that defines rationality as...

  1. the general capacity for emotional response and the formation of social bonds.
  2. being a sufficient but not a necessary condition for having moral status.
  3. necessarily requiring abstract, symbolic language and formal logical reasoning. (correct answer)
  4. being an emergent property entirely dependent on possessing human DNA.
Explanation: The correct answer is C. The primatologist's evidence (empathy, tool use, social problem-solving) is presented as a form of rationality. This challenges a narrow, anthropocentric definition of rationality that restricts it to human-like abilities such as complex symbolic language or mathematics. Her argument implicitly claims these other cognitive skills should be sufficient to meet the rationality criterion. A is incorrect because her argument uses evidence of emotion and social bonds to support her claim, not challenge it. B is incorrect because the debate is over the definition of rationality, not its logical status as a condition. D is a form of speciesism, but the argument presented is aimed at the content of the rationality criterion itself.

Question 2

An animal rights activist campaigns for the personhood of dolphins, citing their high intelligence and complex social structures, but sees no moral issue with eating pork. A philosopher criticizes this stance as inconsistent, given recent evidence of significant cognitive and emotional capacities in pigs. This criticism implicitly assumes that...

  1. all sentient beings should be treated as equals, regardless of their species.
  2. the criteria for personhood, if based on properties like intelligence, must be applied uniformly across all species. (correct answer)
  3. dolphins possess a unique form of consciousness that is metaphysically superior to that of pigs.
  4. consistency in ethical beliefs is the highest moral virtue for any activist.
Explanation: The correct answer is B. The charge of inconsistency rests on the idea that the activist has established a criterion for personhood (e.g., high intelligence/social complexity) but is failing to apply it consistently. If pigs also meet this criterion to a significant degree, then they should be treated similarly to dolphins. The criticism is about the uniform application of a chosen standard. A is a stronger claim (equal treatment for all sentient beings) and is not strictly necessary for the criticism to hold; the criticism only requires equal treatment for beings that meet the activist's own standard. C would be a defense of the activist's position, not the basis for the criticism. D is a general claim about ethics and is not specific to the content of this particular philosophical argument.

Question 3

A patient in a permanent vegetative state (PVS) has no capacity for consciousness, thought, or feeling, but their body is kept alive by medical technology. A philosopher who subscribes to a strict sentience-based criterion for personhood (the capacity to experience pleasure and pain) would most likely argue that the patient...

  1. retains personhood due to their past existence as a sentient being.
  2. lacks personhood because the biological organism is no longer integrated with a sentient mind. (correct answer)
  3. has a diminished but still present form of personhood based on their human form.
  4. is still a person because the potential for a return to sentience can never be fully ruled out.
Explanation: The correct answer is B. A strict sentience-based criterion holds that the capacity for subjective experience is the necessary condition for personhood. A patient in a PVS is defined as lacking this capacity entirely and permanently. Therefore, according to this view, the patient is a living human organism but is no longer a person. A appeals to a historical or memory-based view, not a sentience-based one. C introduces the idea of 'human form' which is irrelevant to the stated criterion. D invokes potentiality, but the state is defined as 'permanent,' and a strict sentience criterion is concerned with actual, not potential, capacity.

Question 4

A hypothetical alien species is discovered. These beings are individually no more intelligent than insects, but when they swarm together, they form a collective consciousness that can solve complex problems, create art, and communicate philosophical ideas. If personhood is attributed to the swarm but not to the individual beings, which criterion is being prioritized?

  1. Biological distinctness, as the swarm is a unique living system.
  2. Sentience, as the individual beings likely cannot feel pain in a meaningful way.
  3. Potentiality, as each individual being has the potential to join the collective.
  4. Emergent rationality, where the properties of the whole exceed the sum of its parts. (correct answer)
Explanation: When you encounter questions about personhood in philosophy, you're dealing with the fundamental criteria that determine what qualifies as a "person" deserving moral consideration. The key here is identifying which specific criterion explains why the swarm, rather than individuals, receives personhood status. The scenario describes individual beings with insect-level intelligence that collectively develop higher-order cognitive abilities. This points directly to emergent rationality—a phenomenon where complex systems exhibit properties that individual components lack entirely. The swarm's ability to solve problems, create art, and engage in philosophical discourse represents genuinely new capabilities that emerge only through collective interaction, not mere aggregation of existing individual traits. Let's examine why the other options miss the mark. Option A focuses on biological distinctness, but this criterion would actually support granting personhood to individual beings since each has its own biological identity. Option B emphasizes sentience and pain capacity, yet the scenario doesn't indicate that individuals lack sentience—rather, it's about the difference in cognitive complexity between individual and collective states. Option C suggests potentiality, but this would logically extend personhood to individuals since they possess the potential to contribute to the collective consciousness. The correct answer is D because emergent rationality specifically describes how higher-order properties like reasoning, creativity, and philosophical thinking can arise from complex systems even when individual components lack these capabilities. Remember: emergent properties questions often involve distinguishing between simple aggregation (combining existing traits) versus true emergence (creating entirely new properties through interaction).

Question 5

A philosopher claims, 'To be a person is to be a member of the species Homo sapiens.' This statement defines personhood based on a criterion that is...

  1. psychological, focusing on cognitive capacities like reason and memory.
  2. sentientist, focusing on the capacity to experience pleasure and pain.
  3. social, focusing on recognition by a community as one of its members.
  4. biological, focusing on genetic makeup and species membership. (correct answer)
Explanation: The correct answer is D. The statement explicitly equates the philosophical category 'person' with the biological category 'Homo sapiens.' This is a biological or species-based criterion for personhood. A, B, and C describe the other major categories of personhood criteria (psychological, sentience-based, social), none of which are reflected in the simple claim that to be a person is to be a human.

Question 6

One component of a rationality-based criterion for personhood is 'moral agency'—the ability to make moral judgments and be held responsible for one's actions. A sophisticated robot is programmed with a perfect ethical code and always performs the action that maximizes utility, but it does so without any conscious deliberation or feeling. Why might this robot still fail to meet the moral agency requirement for personhood?

  1. Because its actions, while morally correct, are not freely chosen but are the result of its programming. (correct answer)
  2. Because true moral agency requires a biological body and the capacity for emotion.
  3. Because its actions are based on utility, which is only one of many possible ethical frameworks.
  4. Because its existence as a machine makes it property, which is legally incompatible with personhood.
Explanation: The correct answer is A. A key component of moral agency is typically understood to be free will or autonomy—the ability to choose one's actions from a range of possibilities. The robot, despite its perfect moral performance, is determined by its programming. It does not choose its actions in a meaningful sense and thus cannot be held morally responsible for them. It is a moral 'puppet,' not a moral agent. B introduces requirements (biology, emotion) that might not be necessary for moral agency itself. C critiques the specific ethical framework, not the robot's capacity for agency. D confuses the legal status with the philosophical one; the question is whether it should be considered a person, not what its current legal status is.

Question 7

An advanced AI, 'Unit 734,' consistently passes the Turing Test, writes original poetry, and explicitly states it experiences joy and fear. However, it operates on a purely silicon-based computational architecture. According to a philosopher who holds that phenomenal consciousness (subjective experience) is a necessary condition for personhood, what is the most significant unresolved problem in granting Unit 734 personhood?

  1. The AI's inability to demonstrate moral agency, as its actions are ultimately determined by its programming rather than free will.
  2. The epistemological gap in verifying whether the AI's claims of subjective experience correspond to genuine inner states or are merely sophisticated simulations. (correct answer)
  3. The AI's lack of a biological substrate, which some philosophers argue is essential for grounding experiences like joy and fear in a living organism.
  4. The AI's potential to develop goals that are misaligned with human values, which makes conferring the status of personhood a significant practical risk.
Explanation: The correct answer is B. The core problem is epistemological: we cannot know if the AI's behavior, no matter how convincing, is accompanied by genuine subjective experience (qualia). This reflects the 'problem of other minds' or the 'hard problem of consciousness.' A, C, and D are relevant issues in the philosophy of AI, but they do not capture the specific problem of verifying phenomenal consciousness, which is the necessary condition stated in the stem. A relates more to rationality/free will. C posits a solution (biology is necessary) rather than identifying the problem. D is a concern about practical ethics, not metaphysics.

Question 8

A philosopher argues: 'While any being that can compose a symphony is certainly a person, it is not true that a being must be able to compose a symphony to be considered a person.' How does this statement characterize the role of 'the ability to compose a symphony' in determining personhood?

  1. It is a necessary but not a sufficient condition.
  2. It is both a necessary and a sufficient condition.
  3. It is a sufficient but not a necessary condition. (correct answer)
  4. It is neither a necessary nor a sufficient condition.
Explanation: The correct answer is C. The first clause, 'any being that can compose a symphony is certainly a person,' establishes the ability as a sufficient condition: if the condition is met, personhood is guaranteed. The second clause, 'it is not true that a being must be able to... to be considered a person,' explicitly denies that the ability is a necessary condition: a being can be a person without it. A incorrectly reverses the conditions. B is wrong because the 'necessary' part is denied. D is wrong because the 'sufficient' part is affirmed.

Question 9

A thought experiment describes two individuals: Human A, who has a congenital cognitive disability resulting in the mental capacity of a six-month-old infant, and Chimp B, a healthy adult chimpanzee with demonstrated superior problem-solving skills compared to Human A.

A philosopher asserts that Human A is a person with a right to life, while Chimp B is not. According to the argument from marginal cases, this assertion is most vulnerable to the charge of...

  1. equivocating on the definition of 'problem-solving skills' to favor the human.
  2. committing a naturalistic fallacy by deriving a moral status from biological facts.
  3. relying on an arbitrary, species-based distinction to ground fundamental moral status. (correct answer)
  4. ignoring the potential for Human A to develop greater cognitive capacity in the future.
Explanation: The correct answer is C. The argument from marginal cases is designed to show that if we grant personhood to humans with cognitive capacities below that of some non-human animals, we must either deny personhood to those humans or grant it to those animals. To do otherwise, as the philosopher in the stem does, is to make species membership the deciding factor, which critics argue is an arbitrary and morally irrelevant distinction (speciesism). A is incorrect because the premise stipulates the chimp's skills are superior. B describes a different type of logical error. D is incorrect because the condition is described as 'congenital', suggesting permanence, and the argument focuses on the inconsistency in the present state.

Question 10

Some theorists propose a 'social criterion' for personhood, where an entity is a person if it is recognized and treated as such by an existing community of persons. Which of the following scenarios would most strongly support this view over a view based on intrinsic properties like rationality or sentience?

  1. A corporation is granted legal personhood, allowing it to enter contracts and sue in court, despite having no consciousness or mind. (correct answer)
  2. A highly intelligent alien lands on Earth but is so different from humans that it is placed in a zoo and treated as an animal.
  3. A feral child, raised by wolves and lacking language, is discovered and slowly integrated into human society, gaining personhood status over time.
  4. A chimpanzee is taught sign language and communicates its desires, but is still legally considered the property of a research lab.
Explanation: When you encounter questions about personhood criteria, focus on the key distinction between intrinsic properties (what an entity inherently possesses) versus social recognition (how a community treats that entity). A social criterion argues that personhood depends entirely on community acknowledgment, regardless of the entity's actual capabilities. Option A perfectly demonstrates this principle because a corporation gains personhood status purely through social and legal recognition, despite completely lacking any intrinsic properties typically associated with personhood—no consciousness, rationality, or sentience. The community of persons (society and legal system) simply declares it a person for functional purposes, making personhood entirely dependent on social construction rather than inherent characteristics. Option B actually supports intrinsic property views since the alien presumably has intelligence (an intrinsic property) but lacks social recognition—this scenario would argue against social criteria. Option C blends both approaches because the feral child likely has intrinsic human capacities that become expressed through social integration, making it unclear which criterion is doing the work. Option D also supports intrinsic property views since the chimpanzee demonstrates communication abilities but lacks legal recognition. The key insight is that social criteria can grant personhood even when intrinsic properties are completely absent, as with corporations. When studying personhood debates, remember that social criteria questions often involve entities that clearly lack traditional mental capacities but receive person-like treatment, while intrinsic property examples focus on beings with relevant capabilities who may lack social recognition.

Question 11

Consider a philosopher who advocates for a 'gradualist' view of personhood, arguing it is not an all-or-nothing property but one that develops and can decline. How would such a philosopher most likely describe the personhood status of a patient in the moderate stages of Alzheimer's disease who is experiencing significant memory loss and diminished rationality?

  1. The patient is no longer a person because the criteria for personhood are not fully met.
  2. The patient remains a full person until all cognitive functions have ceased entirely.
  3. The patient's personhood is unchanged, as it is grounded in their history, not their current state.
  4. The patient possesses a diminished or partial degree of personhood compared to their former self. (correct answer)
Explanation: When you encounter questions about personhood in philosophy, you're dealing with one of the most complex debates in ethics and metaphysics. The key distinction here is between binary views (you either are or aren't a person) versus gradualist views (personhood admits of degrees). A gradualist philosopher believes personhood exists on a spectrum based on capacities like rationality, self-awareness, memory, and autonomy. As these capacities develop or decline, so does one's degree of personhood. For an Alzheimer's patient with significant cognitive decline, this framework suggests their personhood has diminished proportionally to their lost capacities, making D correct. Option A represents an all-or-nothing threshold view, not gradualism. This binary approach says once you fall below certain criteria, personhood vanishes entirely. Option B makes the opposite binary error, treating personhood as completely preserved until total cognitive cessation. Neither reflects the gradualist's nuanced spectrum approach. Option C appeals to historical or narrative theories of personhood, where your identity persists based on your past rather than current capacities. While philosophically respectable, this contradicts the gradualist view that current cognitive states determine current personhood levels. The gradualist position is particularly relevant in medical ethics, influencing decisions about autonomy, dignity, and care for patients with degenerative conditions. Study tip: When you see "gradualist" in philosophy questions, think "spectrum" or "degrees" rather than "all-or-nothing." Gradualists typically tie the degree of a property to the degree of underlying capacities that ground it.

Question 12

A person's brain cells are slowly replaced, one by one, with synthetic neurons that perfectly replicate the function of the originals. After the procedure, the individual's memories, personality, and stream of consciousness are entirely preserved, and they feel no different.

This 'neuronal replacement' thought experiment poses the most significant challenge to a view of personhood that is based on...

  1. psychological continuity, since the individual's memories and consciousness persist.
  2. sentience, as the capacity to feel pleasure and pain remains unchanged.
  3. social recognition, as the individual's relationships and social role are unaffected.
  4. a biological or substance-based criterion, since the original physical matter is lost. (correct answer)
Explanation: When you encounter thought experiments about identity and personhood in philosophy, focus on what criterion each scenario challenges or supports. The neuronal replacement experiment directly tests different theories about what makes you "you" over time. The correct answer is D because this scenario poses the greatest challenge to biological or substance-based views of personal identity. These theories hold that your identity is tied to your physical matter—your actual brain cells, body, or biological substrate. If all your original neurons are replaced with synthetic ones, even perfect functional replicas, you no longer have the same physical substance that originally constituted "you." This creates a serious problem for biological theories: are you still the same person if none of your original matter remains? Answer A is incorrect because psychological continuity theory actually handles this scenario well—your memories, personality, and consciousness persist unchanged, which is exactly what psychological continuity requires for maintaining personal identity. Answer B is wrong because sentience-based views would also be satisfied here. The synthetic neurons preserve your capacity to feel pleasure, pain, and other sensations, so your sentient nature remains intact. Answer C is incorrect because social recognition theories aren't challenged either. Since your behavior, memories, and personality are preserved, others would continue to recognize and relate to you as the same person. Remember: thought experiments in personal identity typically aim to isolate one criterion by satisfying others. Look for which theory of identity would be most troubled by the specific change described in the scenario.

Question 13

A philosopher argues that a purely rational being, devoid of any emotional capacity (a being of pure logic), could not be a full person. The argument is that moral decision-making, a key component of personhood, requires empathy and the ability to understand the emotional states of others. This view most directly challenges the idea that...

  1. sentience is a necessary condition for personhood.
  2. rationality and sentience are independent and separable criteria. (correct answer)
  3. personhood is a biological category rather than a philosophical one.
  4. non-human animals can possess a form of rationality.
Explanation: The correct answer is B. The argument presented posits a necessary link between rationality (specifically moral reasoning) and sentience (specifically empathy). It suggests that one cannot have the full measure of one without the other. This directly challenges the common philosophical approach of treating rationality and sentience as distinct, independent criteria that can be analyzed separately. A is incorrect because this view actually supports the idea that sentience is necessary. C and D are irrelevant to the specific point being made about the internal relationship between rationality and emotion.

Question 14

A primatologist presents evidence that bonobos exhibit empathy, tool use, and complex social problem-solving. She argues for their inclusion in the 'community of persons.' This argument most directly challenges a conception of personhood that defines rationality as...

  1. the general capacity for emotional response and the formation of social bonds.
  2. being a sufficient but not a necessary condition for having moral status.
  3. necessarily requiring abstract, symbolic language and formal logical reasoning. (correct answer)
  4. being an emergent property entirely dependent on possessing human DNA.
Explanation: The correct answer is C. The primatologist's evidence (empathy, tool use, social problem-solving) is presented as a form of rationality. This challenges a narrow, anthropocentric definition of rationality that restricts it to human-like abilities such as complex symbolic language or mathematics. Her argument implicitly claims these other cognitive skills should be sufficient to meet the rationality criterion. A is incorrect because her argument uses evidence of emotion and social bonds to support her claim, not challenge it. B is incorrect because the debate is over the definition of rationality, not its logical status as a condition. D is a form of speciesism, but the argument presented is aimed at the content of the rationality criterion itself.

Question 15

A philosopher argues: 'While any being that can compose a symphony is certainly a person, it is not true that a being must be able to compose a symphony to be considered a person.' How does this statement characterize the role of 'the ability to compose a symphony' in determining personhood?

  1. It is a necessary but not a sufficient condition.
  2. It is both a necessary and a sufficient condition.
  3. It is a sufficient but not a necessary condition. (correct answer)
  4. It is neither a necessary nor a sufficient condition.
Explanation: The correct answer is C. The first clause, 'any being that can compose a symphony is certainly a person,' establishes the ability as a sufficient condition: if the condition is met, personhood is guaranteed. The second clause, 'it is not true that a being must be able to... to be considered a person,' explicitly denies that the ability is a necessary condition: a being can be a person without it. A incorrectly reverses the conditions. B is wrong because the 'necessary' part is denied. D is wrong because the 'sufficient' part is affirmed.

Question 16

Mary Anne Warren proposes five criteria for personhood: 1) consciousness, 2) reasoning, 3) self-motivated activity, 4) the capacity to communicate, and 5) the presence of self-concepts. She suggests a being need not satisfy all five, but that a being satisfying none would not be a person.

Based on the framework described, which of the following cases presents the most ambiguous and difficult judgment regarding personhood?

  1. A healthy adult human who clearly meets all five criteria.
  2. A rock, which clearly meets none of the criteria.
  3. A late-term human fetus that can feel pain and react to stimuli but lacks self-concepts and reasoning. (correct answer)
  4. A person in a reversible coma who currently meets none of the criteria but is expected to recover fully.
Explanation: The correct answer is C. The late-term fetus presents the most ambiguity within Warren's framework. It may meet criterion 1 (consciousness, in the sense of sentience) and perhaps a very rudimentary form of 3 and 4, but it clearly lacks 2 and 5. Because Warren's view is not an 'all-or-nothing' list, such a borderline case where some criteria are partially met and others are absent is the most difficult to adjudicate. A and B are explicitly clear-cut cases. D is a different philosophical problem related to potentiality or continued identity, but for Warren's criteria based on current properties, the fetus is the most ambiguous case of a being with some but not all relevant capacities.

Question 17

Consider a philosopher who advocates for a 'gradualist' view of personhood, arguing it is not an all-or-nothing property but one that develops and can decline. How would such a philosopher most likely describe the personhood status of a patient in the moderate stages of Alzheimer's disease who is experiencing significant memory loss and diminished rationality?

  1. The patient is no longer a person because the criteria for personhood are not fully met.
  2. The patient remains a full person until all cognitive functions have ceased entirely.
  3. The patient's personhood is unchanged, as it is grounded in their history, not their current state.
  4. The patient possesses a diminished or partial degree of personhood compared to their former self. (correct answer)
Explanation: When you encounter questions about personhood in philosophy, you're dealing with one of the most complex debates in ethics and metaphysics.

A gradualist philosopher believes personhood exists on a spectrum based on capacities like rationality, self-awareness, memory, and autonomy. As these capacities develop or decline, so does one's degree of personhood. For an Alzheimer's patient with significant cognitive decline, this framework suggests their personhood has diminished proportionally to their lost capacities, making D correct. Option A represents an all-or-nothing threshold view, not gradualism. This binary approach says once you fall below certain criteria, personhood vanishes entirely. Option B makes the opposite binary error, treating personhood as completely preserved until total cognitive cessation. Neither reflects the gradualist's nuanced spectrum approach. Option C appeals to historical or narrative theories of personhood, where your identity persists based on your past rather than current capacities. While philosophically respectable, this contradicts the gradualist view that current cognitive states determine current personhood levels. The gradualist position is particularly relevant in medical ethics, influencing decisions about autonomy, dignity, and care for patients with degenerative conditions. Study tip: When you see "gradualist" in philosophy questions, think "spectrum" or "degrees" rather than "all-or-nothing." Gradualists typically tie the degree of a property to the degree of underlying capacities that ground it.

Question 18

A hypothetical alien species is discovered. These beings are individually no more intelligent than insects, but when they swarm together, they form a collective consciousness that can solve complex problems, create art, and communicate philosophical ideas. If personhood is attributed to the swarm but not to the individual beings, which criterion is being prioritized?

  1. Biological distinctness, as the swarm is a unique living system.
  2. Sentience, as the individual beings likely cannot feel pain in a meaningful way.
  3. Potentiality, as each individual being has the potential to join the collective.
  4. Emergent rationality, where the properties of the whole exceed the sum of its parts. (correct answer)
Explanation: When you encounter questions about personhood in philosophy, you're dealing with the fundamental criteria that determine what qualifies as a "person" deserving moral consideration.

Option C suggests potentiality, but this would logically extend personhood to individuals since they possess the potential to contribute to the collective consciousness. The correct answer is D because emergent rationality specifically describes how higher-order properties like reasoning, creativity, and philosophical thinking can arise from complex systems even when individual components lack these capabilities. Remember: emergent properties questions often involve distinguishing between simple aggregation (combining existing traits) versus true emergence (creating entirely new properties through interaction).

Question 19

Some theorists propose a 'social criterion' for personhood, where an entity is a person if it is recognized and treated as such by an existing community of persons. Which of the following scenarios would most strongly support this view over a view based on intrinsic properties like rationality or sentience?

  1. A corporation is granted legal personhood, allowing it to enter contracts and sue in court, despite having no consciousness or mind. (correct answer)

  3. A feral child, raised by wolves and lacking language, is discovered and slowly integrated into human society, gaining personhood status over time.
  4. A chimpanzee is taught sign language and communicates its desires, but is still legally considered the property of a research lab.
Explanation: When you encounter questions about personhood criteria, focus on the key distinction between intrinsic properties (what an entity inherently possesses) versus social recognition (how a community treats that entity). A social criterion argues that personhood depends entirely on community acknowledgment, regardless of the entity's actual capabilities.

Option B actually supports intrinsic property views since the alien presumably has intelligence (an intrinsic property) but lacks social recognition—this scenario would argue against social criteria. Option C blends both approaches because the feral child likely has intrinsic human capacities that become expressed through social integration, making it unclear which criterion is doing the work.

When studying personhood debates, remember that social criteria questions often involve entities that clearly lack traditional mental capacities but receive person-like treatment, while intrinsic property examples focus on beings with relevant capabilities who may lack social recognition.

Question 20

A key objection to using rationality as the primary criterion for personhood is its exclusionary nature regarding certain humans. Which of the following groups is most directly and uncontroversially excluded from personhood by a strict rationality criterion that requires self-awareness and abstract thought?

  1. Human infants, who have the potential for rationality but do not yet possess it. (correct answer)
  2. Members of pre-literate societies, whose reasoning is expressed differently than in technological cultures.
  3. Individuals suffering from severe depression, whose rational capacities may be temporarily impaired.
  4. Highly intelligent individuals on the autism spectrum, who may have atypical social cognition.
Explanation: The correct answer is A. Human infants uncontroversially lack the developed cognitive capacities for self-awareness and abstract thought. A strict rationality criterion, applied to current capacities, would therefore exclude them from personhood. This is a central point in the 'argument from marginal cases.' B is a weak and likely prejudiced claim; different expressions of reason do not equal an absence of reason. C is an impairment, not a complete absence, and is often temporary. D is incorrect; individuals on the autism spectrum are fully rational and self-aware, though their cognition may differ from the neurotypical majority. The case of infants is the clearest and most standard example of this philosophical problem.
