Abstract:
While the concepts of common knowledge (we know it and we all know that we all know it…) and distributed knowledge (were we to talk to each other, we would know it) are well-known to epistemologists and epistemic logicians, both ignore the role played by social relationships within our community. I will consider the effect of such relationships in structuring both the content and mode of access that we have to group knowledge, and show that consideration of this structure reveal many distinctions in the way in which knowledge can be shared, and how we reason about this.
