This essay argues that Alvin I. Goldman's truth-linked theory of group knowledge (veritism) omits individual components of social cognition, that all group based theories of knowledge lead to scepticism, and that if any sense is to be made of social knowledge, it must be done on individualist lines. I argue that Goldman's veritism can be reconstructed by adopting a reliabilist theory,social reliabilism. And I argue that Goldman's objections to a particular sort of consensualism are not telling. So there are now (...) two plausible and competing theories of social knowledge-social reliabilism and consensualism. (shrink)

In the tradition of justified true belief theory, I provide an epistemic responsibility-based philosophical analysis of collective knowledge which is both coherentist and reliabilist.

The first section of this paper asks why the notion of consensus has recently come to the fore in the medical humanities, and suggests that the answer is a function of growing technological and professional complexity. The next two sections examine the concept of consensus analytically, citing some of the recent philosophical literature. The fourth section looks at committee deliberations and their desirable outcomes, and questions the degree to which consensus serves those outcomes. In the fifth and last section it (...) is suggested that if I am to subscribe to a consensual outcome responsibly I must be personally committed to it, and that this requires a form of knowledge I call ‘fiduciary’, in this case knowledge of the competence and trustworthiness of other participants in deliberation whose expertise may have influenced my agreement.

Our folk epistemology says that if someone knows that P and tells you that P, then, given the absence of defeaters, if you believe what they tell you, you will come to know that P as well. A speaker's knowledge that P is then, for the most part, enough for a hearer to come to know that P. But there are counterexamples to this principle: testimonial knowledge does not always transfer from the speaker to the hearer. Why should that be (...) so? Because testimonial knowledge arises through the flow of information--from conclusive grounds--from the speaker through the speaker's assertion to the hearer's state of comprehension as of the speaker's assertion. A speaker's belief can be based on conclusive grounds, but the speaker's assertion may fail to provide conclusive grounds to the hearer. Then the hearer won't acquire knowledge, even from a knowledgeable speaker. Knowledge from testimony then works more like knowledge through perception. But wait, you say, that can't be so because testimony involves free will but perception does not. The essay ends with a broadly Hume inspired reply to this objection. (shrink)

The landscape of contemporary epistemology has significantly diversified in the past 30 years, shaped in large part by two complementary movements: virtue and social epistemology. This diversification provides an apt theoretical context for the epistemology of education. No longer concerned exclusively with the formal analysis of knowledge, epistemologists have turned their attention towards individuals as knowers, and the social contexts in which epistemic goods such as knowledge and understanding are acquired and exchanged. As such, the concerns of epistemology have once (...) again aligned with questions lying at the heart of the philosophy of education regarding the nature, aims and practice of education. Employing the conceptual tools and frameworks of the contemporary field, these questions are addressed by both epistemologists and education theorists in the emerging epistemology of education literature.

Endorsing the idea of group knowledge seems to entail the possibility of group belief as well, because it is usually held that knowledge entails belief. It is here studied whether it would be possible to grant that groups can have knowledge without being committed to the controversial view that groups can have beliefs. The answer is positive on the assumption that knowledge can be based on acceptance as well as belief. The distinction between belief and acceptance can be seen as (...) a refinement of the ordinary language concept of belief, and it may be useful in understanding the nature of epistemic justification and classifying various types of epistemic subjects.

This paper states three counterexamples to the claim that testimony cannot generate knowledge, that a hearer can only acquire testimonial knowledge from a speaker who knows: a twins case, the fossil case, and an inversion case. The paper provides an explanation for why testimony can generate knowledge. Testimonial knowledge involves the flow of information from a speaker to a hearer through the linguistic channel.
