Amina, the Moved Examination, and Defeated Testimony
Amina, a final-year student, is told by two classmates that the philosophy examination has been moved from Monday to Tuesday. One classmate says she saw a notice on the department board; the other says a lecturer announced it in a class Amina missed. Amina does not check the official timetable or ask the lecturer. She also remembers that last term a rumour about a room change proved false. She decides to trust the Tuesday date and does not attend on Monday. The examination was in fact held on Monday. Later, the department confirms that a notice had been briefly posted but removed because it was an error. Amina’s classmates sincerely believed the Tuesday date. Was Amina’s belief that the exam was on Tuesday justified? Did she know it? Use epistemic concepts to explain.
1. Assess whether Amina’s belief was epistemically justified. Distinguish justification from truth and from mere sincere belief.

Justification: A belief is justified when it is supported by the evidence available to the agent and formed with appropriate epistemic care. Amina has some evidence: two classmates testify, and one claims direct notice. Testimony can justify belief, but its strength depends on the source’s reliability, independence, and the believer’s defeaters. Here the sources are not independent in a strong sense: one is hearsay. Amina also has a specific defeater from last term’s false rumour, and checking the official timetable or lecturer was easy. Her belief may be psychologically understandable and sincerely held, but it is not well justified. Truth: Justification does not guarantee truth; the notice was erroneous. Belief: Sincere belief alone is not justification. Verdict: weak subjective justification at best; not epistemically justified in the circumstances.
2. Did Amina know the exam date? Explain using a JTB or virtue-reliabilist framework, and say what difference the brief notice makes.

Knowledge: Knowledge requires at least truth, belief, and adequate justification, with no relevant epistemic luck. Amina believed the exam was on Tuesday, but the belief was false, so she did not know. JTB: The truth condition fails outright. Reliabilism: The belief-forming process-trusting unverified and defeater-affected testimony-was unreliable in this environment, so it would not count as knowledge even if the date had happened to be Tuesday. Virtue framework: A conscientious inquirer would have checked an authoritative source; Amina’s credulity falls short of intellectual virtue. Brief notice: The notice explains why the classmates sincerely believed and why the rumour had a basis, but it does not transmit knowledge to Amina. If she had seen the official notice herself and had no defeater, the case would be stronger; a withdrawn erroneous notice is a defeated source, not a licence to believe.
