Epistemic Modal Disagreement

Temporalizing Modal Epistemic Logic

Timed Modal Epistemic Logic, tMEL, is a newly introduced logical framework for reasoning about the modeled agent's knowledge. The framework, derived from the study of Justi cation Logic, is adapted from the traditional Modal Epistemic Logic, MEL, to serve as a logically non-omniscient epistemic logic and dealing with problems where the the temporal constraint is an unavoidable factor. In this p...

Epistemic Relativism and Reasonable Disagreement [version of June, 2007]

I begin with some familiar conceptions of epistemic relativism. One kind of epistemic relativism is descriptive pluralism. This is the simple, non-normative thesis that many different communities, cultures, social networks, etc. endorse different epistemic systems (E-systems), i.e., different sets of norms, standards, or principles for forming beliefs and other doxastic states. Communities try ...

A New Modal Framework for Epistemic Logic

Recent years witnessed a growing interest in non-standard epistemic logics of knowing whether, knowing how, knowing what, knowing why and so on. The new epistemic modalities introduced in those logics all share, in their semantics, the general schema of ∃x φ , e.g., knowing how to achieve φ roughly means that there exists a way such that you know that it is a way to ensure that φ . Moreover, th...
