It is argued that reliance on the testimony of others cannot be viewed as reliance on a kind of evidence. Speech being essentially voluntary, the speaker cannot see his own choice of words as evidence of their truth, and so cannot honestly offer them to others as such. Rather, in taking responsibility for the truth of what he says, the speaker offers a guarantee or assurance of its truth, and in believing him the hearer accepts this assurance. I argue that, (...) contrary to appearances, this account is compatible with the hearer acquiring knowledge, and in fact throws interesting light on the idea of knowledge. -/- . (shrink)

Our trust in the word of others is often dismissed as unworthy, because the illusory ideal of "autonomous knowledge" has prevailed in the debate about the nature of knowledge. Yet we are profoundly dependent on others for a vast amount of what any of us claim to know. Coady explores the nature of testimony in order to show how it might be justified as a source of knowledge, and uses the insights that he has developed to challenge certain widespread assumptions (...) in the areas of history, law, mathematics, and psychology.

This essay critically examines the Assurance View of testimony as put forth by Angus Ross (1986) and Richard Moran (1999). The Assurance View holds that someone who offers testimony gives the hearer a non-evidential justification for belief by assuming responsibility for the truth of her testimony. I agree that testimonial justification depends on the teller’s assumption of her responsibility for her testimony, but argue that it is nevertheless evidential justification. Testimonial justification is a sort of evidence that is within the (...) teller’s power to create or withhold at will, and that power is essential to the justification. (shrink)
