摘要: The intuitive notion of evidence as explored by epistemologists sits somewhere in between
syntax and semantics. We will explore how this can be modeled in terms of so-called neighborhood
models for evidence and its changes over time – at a level of grain that also occurs in other areas of
logical semantics. Technically, we introduce richer modal languages for this setting than the usual ones,
and explore their dynamic logics and model theory, including links with more standard plausibility
models. The talk ends with a list of challenges for the logics presented here, such as reliability and
authority, learning, evidence merge, and other epistemological paradigms of reasons and reasoning.
