Abstract: We often talk about knowledge being transmitted via testimony. This suggests a picture of testimony with striking similarities to memory. For instance, it is often assumed that neither is a generative source of knowledge: while the former transmits knowledge from one speaker to another, the latter preserves beliefs from one time to another. These considerations give rise to a stronger and a weaker thesis regarding the transmission of testimonial knowledge. The stronger thesis is that each speaker in a chain of testimonial transmission must know that p in order to pass this knowledge to a hearer. The weaker thesis is that at least the first speaker must know that p in order for any hearer in the chain to come to know that p via testimony. I argue that both theses are false, and hence testimony, unlike memory, can be a generative source of knowledge.Fricker, Elizabeth. Against Gullibility1994, In: Matilals, Bimal K. & Chakrabarti, A.

Summary: This paper refutes the PR thesis according to which the hearer has such a special presumptive right to trust the speaker's assertion. The refutation consists of 1) arguing against that it is not possible for a hearer to obtain independent confirmation that a given speaker is trustworthy - that what she says will be true; 2) a full rejection to various positive arguments for a PR which may be made.Comment: This paper defends anti-reductionism by refuting arguments for reductionism. It is useful paper for teachings on testimony in a upper-level undergraduate course on epistemology.

Abstract: Testimony is a vital and ubiquitous source of knowledge. Were we to refrain from accepting the testimony of others, our lives would be impoverished in startling and debilitating ways. Despite the vital role that testimony occupies in our epistemic lives, traditional epistemological theories have focused primarily on other sources, such as sense perception, memory, and reason, with relatively little attention devoted specifically to testimony. In recent years, however, the epistemic significance of testimony has been more fully appreciated. I shall here focus on two questions that have received the most attention in recent work in the epistemology of testimony. First, is testimonial knowledge acquired only by being transmitted from speaker to hearer? Second, must a hearer have positive reasons to justifiedly accept a speaker's testimony?Comment: This text will serve as a good introduction to the epistemology of testimony. Aside from its relevance in teaching Epistemology, it will also be of use in teaching Aesthetics where Aesthetic Testimony has become a key topic of debate. Lackey provides various thought experiments which can aid the reader in understanding when knowledge seems to be acquired via testimony, and how this seems to work.

Comment: This is a very good introductory paper on testimonial knowledge and debates between reductivists and non-reductivists. Note that it requires preliminary knowledge on JTB theory.
