Unit quiz: Justification, defeaters and regress

Check understanding, separately from reading

5 questions · 80% to pass · no timer. This quiz checks the lessons in this unit. These authored questions assess recognition and application of the taught distinctions, not professional qualification. You may review the lessons and retry. Repeat attempts reuse the question bank; a remembered answer is not proof of transfer to a new situation.

Saving a lesson records reading only. Previous lesson completions have not been converted into passing scores. You can continue reading without a pass; the assessment remains unpassed.

Question 1

A reliable-looking clock stopped earlier, but you consult it at the moment its hands happen to show the correct time. Your belief is true and ordinarily supported by looking at a clock, yet its truth is accidental. A functioning clock would connect your reading to the changing time rather than coincidence.

What makes the stopped-clock belief an epistemic problem?

Question 2

A photograph seems to show a blue fabric. A trustworthy physical inspection reporting red is rebutting evidence. Learning that the camera applied an unknown color filter undercuts the photograph as evidence, but does not by itself establish red, green, or any particular color.

What does discovering an unknown color filter support by itself?

Question 3

Two people have indistinguishable visual experiences, but one sees normally while the other is systematically deceived. An access-focused view can assign similar internal justification. A reliability-focused view can distinguish the processes’ connection to truth. Their disagreement concerns the standard, not the stipulated experiences.

Which feature can an externalist treat as relevant beyond accessible experience?

Question 4

A reader identifies a label in fog. Classifying the event as ordinary reading may rate it highly; classifying it as reading faint labels in fog may not. Describing it as “the process that produced this correct answer” trivially guarantees success and avoids the real evaluation.

Why is the one-off correct-answer classification inadequate?

Question 5

Asked why you trust a document, you cite an archive; asked why you trust the archive, you cite records. Stopping at direct observation raises the question of why it is basic. Appealing to a network of mutually supporting records raises the question of independent contact with the world.

What challenge specifically faces a merely coherent fictional system?
