Questions: Internalism and Externalism in Epistemology

Question 1

A person has a reliable clairvoyant faculty that genuinely gives accurate information about distant events. They form a belief about a distant city using this faculty, but have no evidence it is reliable and cannot explain why they believe what they do. Is this belief justified, and why do internalists and reliabilists disagree?

• A. Both views agree the belief is justified, since the clairvoyant has access to the right information
• B. Both views agree the belief is unjustified, since there is no causal pathway linking the belief to the facts
• C. Reliabilists say the belief is justified because the faculty reliably produces true beliefs; internalists say it is not because the believer cannot access or articulate any reason for it
• D. Internalists say it is justified because the belief is accurate; reliabilists say it is not because no formal verification was performed

Answer: (C)

The clairvoyant case is the sharpest test case in the internalism-externalism debate. The reliabilist says: justification is about whether the belief-forming process reliably produces true beliefs — and here it does — so the belief is justified regardless of whether the believer can access that reliability. The internalist says: justification requires that the believer have reasons they can recognize on reflection. Since the clairvoyant has no accessible evidence and cannot explain their belief, there are no internal justifying factors, and the belief is unjustified no matter how reliable the faculty actually is. Your intuitions about this case reveal which framework you implicitly adopt.

Question 2

What is the central commitment of access internalism?

• A. Justification depends only on the external facts about how the belief was formed — specifically whether it was formed through perception or testimony
• B. A factor justifies a belief only if the believer can recognize on reflection that it is a reason for that belief — justification requires in-principle accessibility to the believer
• C. Any belief that tracks the truth reliably is automatically justified, as long as the believer is in a normal environment
• D. Justification is determined by whether the community of experts would endorse the belief-forming process

Answer: (B)

Access internalism holds that what makes a belief justified must be accessible to the believer through introspection or reflection. The motivation is epistemic responsibility: if you can be asked 'why do you believe that?' and are expected to produce reasons, then justification must consist of things you can in principle articulate. Factors that influence your belief but that you cannot recognize as reasons — like the reliability of an unconscious process — do not count as justifiers on this view. This preserves the intuition that justified belief is something you are responsible for in a way that unjustified belief is not.

Question 3

On a reliabilist account, a belief formed through a process that reliably produces true beliefs is justified even if the believer cannot articulate why they hold it or explain the process that produced it.

• T. True
• F. False

Answer: True

This is the defining claim of reliabilism, the most prominent externalist theory. Reliabilism locates justification in the objective track record of the belief-forming process, not in the believer's subjective evidence or self-knowledge. A person who accurately reads environmental cues they cannot explicitly describe, a child who forms correct beliefs through testimony without understanding what testimony is, or a person using perceptual faculties they have never analyzed — all count as having justified beliefs on a reliabilist view, as long as the underlying process reliably produces true beliefs. The believer's access to that reliability is irrelevant.

Question 4

Internalists and externalists agree on what justification is but disagree mainly about which specific beliefs happen to be justified.

• T. True
• F. False

Answer: False

The disagreement is far deeper than that — it is about what justification fundamentally is, not just which beliefs have it. Internalists hold that justification is constituted by internal, accessible mental states (reasons, evidence, coherence). Externalists hold that justification is constituted by objective, external facts about the belief-forming process (reliability, causal history, tracking truth). These are competing accounts of justification's nature, not competing lists of justified beliefs. Cases like the clairvoyant show they can give opposing verdicts on specific beliefs, precisely because they define justification differently.

Question 5

A person raised in isolation develops highly accurate beliefs about animal behavior through unconscious pattern recognition they cannot consciously articulate. How would an internalist and a reliabilist each evaluate whether these beliefs are justified?

Model answer: The reliabilist would say the beliefs are justified: the belief-forming process (unconscious pattern recognition) reliably produces true beliefs about animal behavior, and that is what justification consists in. The fact that the person cannot articulate their process is irrelevant to the reliabilist. The internalist would say the beliefs may not be justified: justification requires accessible reasons the believer can recognize on reflection. If the person cannot point to any reason for their belief — cannot say 'I believe this because I noticed X, Y, Z' — then there are no internal justifying factors, even if the belief happens to be accurate. The internalist might acknowledge the beliefs track truth but deny that this alone constitutes justification.

This case parallels both Spivak's native tribesperson example and the broader internalism-externalism debate. The key philosophical issue is whether epistemic responsibility (being able to answer 'why do you believe that?') is essential to justification, or whether justification is a more objective, third-personal property that you have or lack independent of self-awareness. The answer determines whether knowledge requires a reflective, self-knowing epistemic subject or merely a reliable truth-tracking system.
