Title: Evidence Logic and Culprits for the Failure of Epistemic Closure
Date and Time: Thursday, January 23, 2014, 15:30-17:30
Venue: Science Park 107, Room F1.15
Abstract: Inspired by J. van Benthem and E. Pacuit’s paper Dynamic Logics of Evidence-Based Beliefs, a new evidence logic is developed, in which a series of evidence-related concepts are defined and based on them the concept of evidence-based knowledge can be defined. In the first part of the talk, I will introduce this new evidence logic and in the second part of the talk I will make use of the newly defined concept of knowledge to discuss one problem in epistemology — the failure of epistemic closure. I will point out that there are three culprits for the failure of epistemic closure, and also provide a dynamic perspective on how to save the failure of epistemic closure.
