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.

I discuss several views of the nature of testimony and show how each proposal has importantly different problems. I then offer a diagnosis of the widespread disagreement regarding this topic; specifically, I argue that our concept of testimony has two different aspects to it. Inadequate views of testimony, I claim, result either from collapsing these two aspects into a single account or from a failure to recognize one of them. Finally, I develop an alternative view of testimony that captures both (...) aspects of the nature of testimony and thereby provides the basis for an illuminating theory of testimony's epistemological significance.

In a recent paper titled “Content Preservation”, Tyler Burge argues that certain psychological processes play a purely preservative role, and not a justificatory role. Burge’s claim is that the justificatory force of the beliefs sustained by these processes is independent of features of these processes, such as their reliability. The function of these psychological processes is merely to preserve the beliefs in order to “assure the proper working of other cognitive capacities over time”. In particular, Burge claims that the memory (...) processes underlying deductive reasoning and the psychological processes underlying verbal communication are purely preservative. (shrink)

An influential argument for anti-reductionism about testimony, due to CAJ Coady, fails, because it assumes that an inductive global defense of testimony would proceed along effectively behaviorist lines. If we take seriously our wealth of non-testimonially justified folk psychological beliefs, the prospects for inductivism and reductionism look much better.

Contemporary analytic epistemology exhibits an individualistic bias. The standard analyses of knowledge found in current epistemological discussions assume that the only epistemic agents worthy of philosophical consideration are individual cognizers. The idea that collectives could be genuine knowers has received little, if any, serious consideration. This individualistic bias seems to be motivated by the view that epistemology is about things that go on inside the head. In this paper I challenge this type of epistemic individualism by arguing that certain groups (...) are intentional agents and that cognition occurs at the level of groups. In section I, I extend a plausible and well-defended account of individual intentionality to organizations. In section II, I appeal to research on distributed cognition in order to challenge the view that cognition occurs exclusively in the individual mind-brain. Having established that groups can be believers and cognizers, I turn to the issue of the justification of group belief. In section III, consider whether a reliabilist account of justification can be extended to groups. (shrink)
