 A further controversy concerns the places of testimony and trust in the classroom: In what circumstances if any ought students to trust their teachers’ pronouncements, and why? Here the epistemology of education is informed by social epistemology, specifically the epistemology of testimony; the familiar reductionism/anti-reductionism controversy there is applicable to students and teachers. Anti-reductionists, who regard testimony as a basic source of justification, may with equanimity approve of students’ taking their teachers’ word at face value and believing what they say; reductionists may balk. Does teacher testimony itself constitute good reason for student belief?
