Title: Epistemic logic and the problem of logical omniscience
Speaker：Ren-June Wang （王仁俊），中正大学
Time: May 19th 3：10-6：00pm 北大二教525
Abstract:
In this talk, I try to sort out the source of the problem of logical omniscience in the search of proper logical formalism for epistemic notions such as knowledge and belief. The source, I believe, comes from three different assumptions that are normally imposed on a single epistemic formalism: 1) the intended concept to be dealt with by the formalism is explicit knowledge (or belief), instead of implicit 2) the modeled agent is a competent deductive reasoner and the logical relation between the known propositions or believed propositions of the modeled agent is a direct reflection of this competence, and 3) the modeled agent is a realistic one in the sense of not knowing all the logical consequences of her knowledge. Thus the problem of logical omniscience is the result of the difficulty of reconciling these assumptions in the traditional way of dealing with the subject. After the analysis, a suggested formalism is given.
