Question 1

A person has a phobia of flying. Before a flight, they form the belief, 'This plane will crash.' They have no evidence for this belief; in fact, they have strong statistical evidence against it. By a one-in-a-billion chance, the plane does crash. Which of the following evaluations of the person's pre-flight belief is most accurate?

  1. A foundationalist would say the belief was justified because it was based on the strong, basic feeling of fear.
  2. A coherentist would say the belief was justified because it cohered with the person's emotional state.
  3. All three theories would agree the belief was justified because it turned out to be true.
  4. A reliabilist would say the belief was unjustified because it was formed by an unreliable process (fear-based wishful thinking). (correct answer)
Explanation: This question tests your understanding of three major theories of epistemic justification: foundationalism, coherentism, and reliabilism. The key insight is that these theories focus on why and how beliefs are formed, not whether they happen to be true. Answer D correctly identifies the reliabilist perspective. Reliabilism judges beliefs based on whether they're produced by reliable belief-forming processes—methods that generally lead to true beliefs. Even though this person's belief turned out true, it was formed through fear and phobia rather than evidence or reliable reasoning. Since phobias systematically produce false beliefs about danger, reliabilism would consider this belief unjustified regardless of the lucky outcome. Answer A misrepresents foundationalism. While foundationalists believe some beliefs can be "basic" or self-evident, they don't consider mere feelings or emotions as automatically providing justification. Fear alone doesn't create properly basic beliefs about external facts like plane crashes. Answer B misunderstands coherentism. Coherentists care about how beliefs fit together logically within a person's overall belief system. Here, the crash belief directly contradicts the person's statistical knowledge about flight safety, making it incoherent rather than coherent with their broader beliefs. Answer C makes a crucial error: none of these theories equate justification with truth. A belief can be true but unjustified (like lucky guesses) or false but justified (like reasonable conclusions from misleading evidence). Remember: epistemic justification theories evaluate the process of belief formation, not lucky outcomes. Focus on whether the reasoning method is sound, not whether it accidentally succeeded.

Question 2

Some foundationalists argue that a belief is justified if it is based on an 'infallible' foundation (e.g., a logically certain proposition). Some coherentists argue a belief is justified if it belongs to a 'perfectly' coherent system. A major conceptual advantage of reliabilism over these specific versions of its rival theories is that reliabilism...

  1. provides a clear, algorithmic way to measure the degree of coherence or infallibility.
  2. allows for justification to come in degrees, corresponding to the degree of reliability of the process. (correct answer)
  3. is the only theory that requires justified beliefs to be true, thereby solving the Gettier problem.
  4. better accounts for the justification of a priori beliefs, such as those in mathematics and logic.
Explanation: Strong forms of foundationalism (requiring infallible foundations) and coherentism (requiring perfect coherence) set a very high bar for justification, one that many of our everyday beliefs might not meet. A key feature and advantage of reliabilism is its inherent flexibility. Since reliability is a matter of frequency (the ratio of true to false beliefs produced), it is naturally a graded concept. A process can be highly reliable, moderately reliable, or barely reliable. This allows reliabilism to easily account for the intuition that justification is not an all-or-nothing affair; beliefs can be more or less justified depending on the quality of the process that produced them. This provides a more nuanced and psychologically realistic account of justification than the strict, all-or-nothing versions of the other theories.

Question 3

An internalist theory of justification, such as classical foundationalism or coherentism, posits that justification is determined by factors to which the believer has reflective access. An externalist theory, like reliabilism, denies this. Consider a belief that is both part of a highly coherent belief system and the product of a reliable cognitive process. What is the crucial point of disagreement between an internalist coherentist and an externalist reliabilist about this belief's justification?

  1. The reliabilist would claim the belief is justified even if the agent is unaware of the process's reliability, while the coherentist would insist justification requires the agent's awareness of the belief's coherence. (correct answer)
  2. The coherentist would deny the belief is justified if the reliable process produced a belief that introduces a contradiction, while the reliabilist would still count it as justified due to the process's track record.
  3. The reliabilist would argue that coherence is merely a symptom of a reliable process, while the coherentist would argue that a reliable process is only useful because it tends to produce coherent systems.
  4. The reliabilist would hold that the belief is justified regardless of its truth value, whereas the coherentist would hold that its coherence with other true beliefs is what constitutes justification.
Explanation: This question gets at the core of the internalist/externalist divide. For the reliabilist, the fact of reliability is what confers justification, regardless of whether the agent knows or can reflect upon that fact. For the coherentist (an internalist), justification is constituted by the logical and explanatory relations among the agent's beliefs, something the agent can, in principle, reflect upon. Therefore, the coherentist requires awareness (at least in principle) of the coherence, while the reliabilist makes no such requirement for the process's reliability. Choice A captures this essential distinction about the necessity of cognitive access for justification.

Question 4

A potential weakness of foundationalism is the challenge of characterizing basic beliefs in a way that is both strong enough to support the superstructure of knowledge and plausible in its own right. A potential weakness of coherentism is that it seems to sever the link between justification and truth. How does reliabilism propose to avoid both of these specific problems simultaneously?

  1. By defining basic beliefs as those produced by reliable processes, and defining coherence in terms of a process's reliability.
  2. By making truth a necessary condition for justification, and by requiring that all justified beliefs be based on indubitable foundations.
  3. By arguing that only coherent belief systems can be produced by reliable processes, thus merging the core tenets of all three theories.
  4. By grounding justification in truth-conducive processes, it builds in a link to truth, and by not requiring basic beliefs, it avoids the problem of characterizing them. (correct answer)
Explanation: When you encounter questions about epistemological theories, focus on how each theory addresses the twin challenges of justification: grounding knowledge securely while maintaining a connection to truth. Reliabilism offers an elegant solution by grounding justification in reliable cognitive processes—mechanisms that typically produce true beliefs under normal conditions. This approach simultaneously tackles both major problems. Since reliable processes are truth-conducive by definition, reliabilism maintains an essential link between justification and truth, avoiding coherentism's weakness. And because reliabilism doesn't require foundational basic beliefs at all—instead focusing on the reliability of belief-forming processes—it sidesteps foundationalism's struggle to characterize basic beliefs that are both epistemically strong and plausible. Answer A incorrectly suggests reliabilism redefines basic beliefs and coherence, when reliabilism actually abandons the concept of basic beliefs entirely. Answer B describes foundationalism with additional truth requirements, not reliabilism's distinctive approach. Answer C wrongly claims reliabilism merges all three theories by arguing only coherent systems can be reliable—this misrepresents reliabilism's focus on individual processes rather than systematic coherence. Answer D correctly captures reliabilism's dual strategy: grounding justification in truth-conducive processes (solving coherentism's truth problem) while avoiding the need for basic beliefs altogether (solving foundationalism's characterization problem). Remember that reliabilism's key insight is shifting focus from properties of beliefs themselves to properties of the processes that generate them—this process-centered approach is what allows it to avoid both traditional problems.

Question 5

Imagine a juror, Maria, who believes a defendant is guilty. Her belief is based on a highly coherent story pieced together from circumstantial evidence. Every piece of evidence reinforces every other piece. However, the entire body of evidence was fabricated by a corrupt detective, and hidden security footage, which Maria has not seen, completely exonerates the defendant.

This scenario presents the most significant challenge for which theory of justification, and why?

  1. Foundationalism, because Maria's belief lacks a solid, indubitable experiential foundation, as shown by the existence of countervailing evidence.
  2. Reliabilism, because the cognitive process of evaluating coherent narratives is generally unreliable for determining guilt in legal cases.
  3. Coherentism, because it illustrates the 'isolation objection'—a belief system can be perfectly coherent yet completely detached from reality and therefore false. (correct answer)
  4. All three theories equally, as they all struggle to account for justification in the face of deliberately misleading evidence.
Explanation: This scenario perfectly illustrates the 'isolation objection,' a classic and powerful critique of coherentism. The theory holds that justification is a matter of a belief's coherence with other beliefs. Maria's belief system is highly coherent. Yet, because it has no required connection to an external reality or truth-tracking foundation, it is entirely wrong. This highlights the worry that coherence alone is insufficient for justification because an internally consistent set of beliefs can be systematically false. Foundationalism and reliabilism, by contrast, demand a link to the external world (via experience or reliable processes), which is precisely what is missing in Maria's reasoning.

Question 6

A scientist holds a belief in a complex theory. A foundationalist might trace its justification back to basic observational data. A coherentist might point to the theory's explanatory power and fit with other established theories. How would a reliabilist's analysis of the scientist's justification differ most significantly from these two approaches?

  1. The reliabilist would focus on the logical validity of the inferences the scientist used to derive the theory from the data.
  2. The reliabilist would assess whether the 'scientific method,' as practiced by the scientist, has a high truth-conduciveness ratio in the long run. (correct answer)
  3. The reliabilist would deny that the belief is justified until the theory has been conclusively proven to be true.
  4. The reliabilist would equate the justification with the degree of subjective certainty the scientist feels about the theory.
Explanation: The key shift in a reliabilist analysis is from the evidence (foundationalist) or the belief system's structure (coherentist) to the process of belief formation. For the reliabilist, the justification of the scientist's belief depends on whether the process used—the scientific method, including observation, hypothesis formation, testing, etc.—is a reliable one. This means evaluating the general track record of that method in producing true beliefs. This external, process-oriented focus is fundamentally different from the internalist focus on evidence or coherence. B captures this shift perfectly.

Question 7

A scientist holds a belief in a complex theory. A foundationalist might trace its justification back to basic observational data. A coherentist might point to the theory's explanatory power and fit with other established theories. How would a reliabilist's analysis of the scientist's justification differ most significantly from these two approaches?

  1. The reliabilist would focus on the logical validity of the inferences the scientist used to derive the theory from the data.
  2. The reliabilist would assess whether the 'scientific method,' as practiced by the scientist, has a high truth-conduciveness ratio in the long run. (correct answer)
  3. The reliabilist would deny that the belief is justified until the theory has been conclusively proven to be true.
  4. The reliabilist would equate the justification with the degree of subjective certainty the scientist feels about the theory.
Explanation: The key shift in a reliabilist analysis is from the evidence (foundationalist) or the belief system's structure (coherentist) to the process of belief formation. For the reliabilist, the justification of the scientist's belief depends on whether the process used—the scientific method, including observation, hypothesis formation, testing, etc.—is a reliable one. This means evaluating the general track record of that method in producing true beliefs. This external, process-oriented focus is fundamentally different from the internalist focus on evidence or coherence. B captures this shift perfectly.

Question 8

Consider the belief 'I seem to be seeing a red screen'. According to a classical foundationalist, this belief about an appearance can be a properly basic belief. Why would a coherentist object to classifying this belief as 'foundational'?

  1. A coherentist would argue that the belief is justified by a reliable perceptual process, not by its intrinsic properties.
  2. A coherentist would argue that even this belief's justification depends on other background beliefs, such as 'I know what red is' and 'I am not currently hallucinating'. (correct answer)
  3. A coherentist would argue that such a belief is too trivial to serve as a foundation for a complex belief system.
  4. A coherentist would accept it as foundational but deny that any non-basic beliefs can be inferred from it.
Explanation: A core tenet of coherentism is the rejection of the foundationalist's distinction between basic and non-basic beliefs. Coherentists argue that no belief is justified in isolation. Even a seemingly simple belief about one's own sensory state, like 'I seem to see red', derives its justification from its place in a wider web of beliefs. To be justified in believing 'I seem to see red', one must possess ancillary concepts and beliefs, such as what 'red' means, what 'seeing' is, and that one's senses are generally trustworthy. These background beliefs provide the context in which the specific perceptual belief becomes justified. Thus, its justification is not self-contained but depends on coherence with this background system. Choice B captures this classic coherentist critique.

Question 9

An epistemologist argues: 'My belief that 2+2=4 is not justified because it fits well with my other mathematical beliefs, nor because my math teachers were reliable. It is justified simply because I apprehend its truth directly and non-inferentially. Its justification does not depend on any other belief I hold.'

This epistemologist's argument for the justification of their belief most closely aligns with the principles of which theory?

  1. Coherentism, as the belief's justification is ultimately tied to its role within the entire system of mathematical beliefs.
  2. Reliabilism, as the cognitive faculty of mathematical intuition is a highly reliable process for forming true beliefs about arithmetic.
  3. Foundationalism, as the belief is presented as a properly basic belief justified directly by rational intuition, not by inference from other beliefs. (correct answer)
  4. A hybrid of foundationalism and reliabilism, as direct apprehension is considered a foundational, reliable cognitive process.
Explanation: The argument describes a belief that is non-inferentially justified through direct apprehension. This is the hallmark of a 'properly basic belief' in foundationalism. The epistemologist explicitly denies that the justification comes from coherence with other beliefs (ruling out coherentism) or from the reliability of its source (ruling out a pure reliabilist account). The justification is claimed to be intrinsic to the belief itself, apprehended via rational intuition, which serves as a foundation for other beliefs. This is a classic example of a foundationalist justification structure for a priori beliefs.

Question 10

Consider a belief B that is justified for a person S. A foundationalist claims B is justified because it is supported by basic belief A. A coherentist claims B is justified because it coheres with beliefs C, D, and E. A reliabilist claims B is justified because it was produced by reliable process P. Now, suppose we discover that basic belief A is false. How would this discovery impact the analyses of the three theories?

  1. For the foundationalist, the justification for B is defeated. For the coherentist and reliabilist, the justification for B is unaffected, as it did not depend on A.
  2. For all three theories, the justification for B is defeated because justification requires truth, and the chain of justification is now rooted in a falsehood.
  3. For the foundationalist and coherentist, the justification for B is weakened or defeated. For the reliabilist, the justification is unaffected unless A's falsity indicates process P is unreliable. (correct answer)
  4. For the foundationalist, the justification for B is defeated. For the coherentist, the justification is also defeated because a falsehood reduces coherence. For the reliabilist, the justification is unaffected.
Explanation: This question tests the implications of introducing a falsehood into the justifying structure of each theory. For the foundationalist, if a foundation (A) is false, any belief (B) built upon it loses its justification. For the coherentist, introducing a falsehood (A) into the belief system would likely create incoherence with other beliefs, thus weakening or defeating the justification for B. The impact depends on the centrality of A. For the reliabilist, the justification of B depends on the process P that produced it, not on belief A. The falsity of A is irrelevant to B's justification unless it provides evidence that the process P which produced B is itself unreliable. Therefore, the reliabilist account is the most insulated from the falsity of other beliefs. Choice C correctly identifies these distinct consequences.

Question 11

Philosopher Laurence BonJour's 'New Evil Demon' problem asks us to imagine a person who is a victim of a Cartesian demon, such that all their perceptual experiences are systematically deceptive. This person's beliefs are formed via processes that are, in this demonic world, completely unreliable. However, from the victim's own perspective, their beliefs seem perfectly reasonable and well-supported by evidence. This thought experiment is primarily intended to challenge which theory of justification?

  1. Coherentism, because the demon could ensure that the victim's beliefs are systematically incoherent.
  2. Foundationalism, because the victim lacks any genuinely self-evident foundational beliefs to ground their system.
  3. Reliabilism, because it implies the victim has no justified beliefs, which clashes with the strong intuition that they are reasoning responsibly. (correct answer)
  4. Both Foundationalism and Coherentism, because internalist theories cannot account for justification when the external world does not match one's beliefs.
Explanation: The New Evil Demon problem is a direct challenge to externalist theories like reliabilism. The victim in the scenario is, from an internal perspective, epistemically identical to a normal person. They reason carefully from their experiences to their beliefs. Intuitively, we want to say they are being rational and their beliefs are justified. However, because they are in a demon world, their belief-forming processes (like perception) are completely unreliable. Reliabilism is therefore forced to conclude that their beliefs are unjustified. This clashes with the intuition that justification should be about epistemic responsibility, which the victim clearly exhibits. The problem supports internalist views (foundationalism and coherentism), which would grant that the victim's beliefs are justified because they are properly based on their available evidence and internal states.

Question 12

A detective investigates a crime. She has three pieces of evidence: (1) a witness testimony, (2) a fingerprint match, and (3) a motive. None of these pieces of evidence, on its own, would be sufficient to justify believing the suspect is guilty. However, taken together, they form a compelling, interlocking case where each piece of evidence makes the others more credible.

The structure of the detective's justification for her belief in the suspect's guilt is most analogous to the structure proposed by which theory?

  1. Foundationalism, where each piece of evidence acts as a mini-foundation, and together they are strong enough to support the conclusion.
  2. Reliabilism, because the process of combining multiple forms of evidence is a reliable method for reaching a correct verdict.
  3. Coherentism, as the justification arises not from any single piece of evidence but from the mutual support and explanatory coherence of the entire set. (correct answer)
  4. All three theories, as they all recognize that stronger evidence leads to a higher degree of justification.
Explanation: This scenario is a classic illustration of coherentist justification. The key feature is that no single belief serves as a foundation. Instead, the justification is a holistic property of the entire system of beliefs. The witness testimony, fingerprint, and motive mutually reinforce one another, creating a coherent narrative. This web-like structure of mutual support, where the whole is epistemically stronger than the sum of its parts, is the central metaphor of coherentism. Foundationalism would require at least one piece of evidence to be 'basic' and support the others in a more linear fashion. Reliabilism focuses on the process, which is a plausible analysis, but the description of the structure of the evidence itself points most directly to coherentism.

Question 13

Imagine a person, Sam, who was raised in a perfectly coherent but factually incorrect belief system (e.g., a scientific theory that has since been superseded, like Ptolemaic astronomy). Upon encountering new evidence, Sam revises his beliefs. A moderate foundationalist and a coherentist could both agree that Sam's new beliefs are more justified. However, they would disagree about why. What is the most likely point of their disagreement?

  1. The foundationalist would claim justification increased because the new beliefs are based on more reliable cognitive processes.
  2. The coherentist would claim justification increased because the new beliefs are more likely to be true, while the foundationalist would focus on their practical utility.
  3. The coherentist would claim the old system was never justified, while the foundationalist would argue it had a degree of justification based on the evidence available at the time.
  4. The foundationalist would claim justification increased because the new beliefs are better grounded in perceptual experience (a foundation), while the coherentist would point to the increased explanatory coherence of the new system. (correct answer)
Explanation: When you encounter questions about epistemological theories, focus on each theory's core mechanism for justification. Foundationalism and coherentism offer fundamentally different explanations for why beliefs gain or lose justification. Answer D correctly captures this distinction. A moderate foundationalist would argue that Sam's new beliefs are better justified because they rest on more reliable foundational sources—particularly updated perceptual evidence and empirical observations that serve as the bedrock for the belief system. For foundationalists, justification flows upward from these basic, self-evident foundations. Meanwhile, a coherentist would emphasize that the new belief system forms a more coherent, internally consistent web of beliefs with greater explanatory power than the old Ptolemaic system. Answer A incorrectly focuses on cognitive processes, which is more relevant to reliabilist theories than to the foundationalist-coherentist debate. Answer B mischaracterizes both positions—foundationalists don't primarily focus on practical utility, and coherentists aren't necessarily more concerned with truth-likelihood than foundationalists. Answer C gets the disagreement backwards: a moderate foundationalist would likely acknowledge that the old system had some justification based on available evidence, while a coherentist might be more willing to say the old system retained justification as long as it was internally coherent. The key study tip: Remember that foundationalists always trace justification back to basic, foundational beliefs (often perceptual), while coherentists focus on how well beliefs fit together as a unified system. When comparing their approaches, look for explanations that highlight these distinct justification mechanisms.

Question 14

A central motivation for both foundationalism and coherentism is solving the epistemic regress problem. How do their proposed solutions fundamentally differ in structure?

  1. Foundationalism solves the regress by positing beliefs justified by reliable processes, while coherentism solves it by positing beliefs justified by their explanatory power.
  2. Foundationalism terminates the regress with non-doxastic justifiers like experience, while coherentism terminates it with a set of voluntarily accepted axioms.
  3. Foundationalism posits a linear or asymmetrical structure of justification ending in basic beliefs, while coherentism posits a holistic, non-linear structure of mutual support. (correct answer)
  4. Foundationalism argues the regress is infinite but virtuous, while coherentism argues the regress must be stopped by an appeal to pragmatic considerations.
Explanation: The core structural difference lies in the direction and nature of justification. Foundationalism sees justification as a one-way street, flowing from foundational (basic) beliefs to non-basic beliefs, thus forming a linear chain or pyramid that must terminate. Coherentism rejects this linear model, arguing that justification arises from the way beliefs in a system mutually support one another in a web-like, holistic, or non-linear fashion. The regress isn't 'stopped' at one point but is contained within the circle of the coherent system. Choice C accurately describes this fundamental structural contrast.

Question 15

An epistemologist argues: 'My belief that 2+2=4 is not justified because it fits well with my other mathematical beliefs, nor because my math teachers were reliable. It is justified simply because I apprehend its truth directly and non-inferentially. Its justification does not depend on any other belief I hold.'

This epistemologist's argument for the justification of their belief most closely aligns with the principles of which theory?

  1. Coherentism, as the belief's justification is ultimately tied to its role within the entire system of mathematical beliefs.
  2. Reliabilism, as the cognitive faculty of mathematical intuition is a highly reliable process for forming true beliefs about arithmetic.
  3. Foundationalism, as the belief is presented as a properly basic belief justified directly by rational intuition, not by inference from other beliefs. (correct answer)
  4. A hybrid of foundationalism and reliabilism, as direct apprehension is considered a foundational, reliable cognitive process.
Explanation: The argument describes a belief that is non-inferentially justified through direct apprehension. This is the hallmark of a 'properly basic belief' in foundationalism. The epistemologist explicitly denies that the justification comes from coherence with other beliefs (ruling out coherentism) or from the reliability of its source (ruling out a pure reliabilist account). The justification is claimed to be intrinsic to the belief itself, apprehended via rational intuition, which serves as a foundation for other beliefs. This is a classic example of a foundationalist justification structure for a priori beliefs.

Question 16

A key objection to reliabilism is the 'generality problem.' Which of the following scenarios best illustrates this specific problem?

  1. A person with a rare brain condition forms 100% true beliefs about the future but has no reason to trust them, making the justification seem unearned.
  2. A person sees a dog in a field. The process could be described as 'vision,' 'vision in good light,' or 'vision of a medium-sized object at 50 yards.' The reliability score changes dramatically depending on which description is used. (correct answer)
  3. A person has a perfectly coherent set of beliefs about astronomy, but this system was formed by reading astrology charts, which is an unreliable process.
  4. A person holds a justified true belief that their friend owns a Ford, but their evidence is that they saw them driving one, not knowing it was a rental car.
Explanation: The generality problem is about how to define the specific 'type' of belief-forming process being evaluated for reliability. Any single belief formation (a token) can be an instance of many different process types. Choice B perfectly illustrates this: 'vision' might be quite reliable, 'vision of objects at 50 yards' might be less so, and 'vision of a specific breed of dog at that distance' might be even less reliable. Since reliabilism ties justification to the reliability of the process type, the inability to non-arbitrarily specify the relevant type is a major challenge. The other options describe different epistemic problems: A is the clairvoyance problem, C is the isolation objection for coherentism, and D is a Gettier problem.

Question 17

An internalist theory of justification, such as classical foundationalism or coherentism, posits that justification is determined by factors to which the believer has reflective access. An externalist theory, like reliabilism, denies this. Consider a belief that is both part of a highly coherent belief system and the product of a reliable cognitive process. What is the crucial point of disagreement between an internalist coherentist and an externalist reliabilist about this belief's justification?

  1. The reliabilist would claim the belief is justified even if the agent is unaware of the process's reliability, while the coherentist would insist justification requires the agent's awareness of the belief's coherence. (correct answer)
  2. The coherentist would deny the belief is justified if the reliable process produced a belief that introduces a contradiction, while the reliabilist would still count it as justified due to the process's track record.
  3. The reliabilist would argue that coherence is merely a symptom of a reliable process, while the coherentist would argue that a reliable process is only useful because it tends to produce coherent systems.
  4. The reliabilist would hold that the belief is justified regardless of its truth value, whereas the coherentist would hold that its coherence with other true beliefs is what constitutes justification.
Explanation: This question gets at the core of the internalist/externalist divide. For the reliabilist, the fact of reliability is what confers justification, regardless of whether the agent knows or can reflect upon that fact. For the coherentist (an internalist), justification is constituted by the logical and explanatory relations among the agent's beliefs, something the agent can, in principle, reflect upon. Therefore, the coherentist requires awareness (at least in principle) of the coherence, while the reliabilist makes no such requirement for the process's reliability. Choice A captures this essential distinction about the necessity of cognitive access for justification.

  3. Reliabilism, because it implies the victim has no justified beliefs, which clashes with the strong intuition that they are reasoning responsibly. (correct answer)
  4. Both Foundationalism and Coherentism, because internalist theories cannot account for justification when the external world does not match one's beliefs.
Explanation: The New Evil Demon problem is a direct challenge to externalist theories like reliabilism. The victim in the scenario is, from an internal perspective, epistemically identical to a normal person. They reason carefully from their experiences to their beliefs.

Question 20

Which of the following statements represents a point of agreement between a classical foundationalist and a coherentist, in opposition to a process reliabilist?

  1. A belief cannot be justified unless it is true.
  2. The structure of a belief system is always hierarchical.
  3. Justification is a normative concept related to epistemic responsibility. (correct answer)
  4. Sensory experience is the ultimate source of all justification.
Explanation: This question asks for the common ground between the two major internalist theories against the externalist one. Both foundationalism and coherentism are internalist, meaning they connect justification to factors accessible to the agent, such as their evidence and the logical relations between their beliefs. This connection makes justification a matter of being epistemically responsible or rational from the agent's own perspective. Reliabilism, being externalist, disconnects justification from the agent's perspective. A person can have a justified belief via a reliable process they know nothing about (like the clairvoyant), so for reliabilism, justification is not necessarily tied to responsibility. Therefore, C is the point of agreement between the internalist theories against the externalist one.
