Actions that Make us Know
Johan van Benthem

Abstract:
This is an extended version of "On What One May Come to Know"
(Aanalysis 2004) explaining in more detail how dynamic epistemic logic
provides a new take on philosophical puzzles concerning learnability
of current truths and verificationism. The paper will be a chapter in
the forthcoming collection J. Salerno, ed., "The Paradox of
Knowability", which will have an up-to-date survey of current
approaches to these intriguing problems.
