Sub-Kripkean epistemic models I
Sergei Artemov
The CUNY Graduate Center
Kripke models provide a versatile semantical tool in modal logic. It appears that when Kripkean methods were adopted in formal epistemology “as is” a key hidden assumption has been overlooked: the very truth condition of a knowledge assertion presupposes that the model itself is common knowledge among the agents. Naturally, this covers only well-controlled epistemic scenarios and leaves off scope numerous situations with partial/asymmetric knowledge. In this talk, we
1) offer a theory of sub-Kripkean epistemic models for unimodal logics;
2) discuss research directions for multi-agent cases.
