The Logic of Knowledge and the Flow of Information
In this paper I look at Fred Dretskes account of information and knowledge as developed in Knowledge and The Flow of Information. In particular, I translate Dretskes probabilistic definition of information to a modal logical framework and subsequently use this to explicate the conception of information and its flow which is central to his account, including the notions of channel conditions and relevant alternatives. Some key products of this task are an analysis of the issue of information closure and an investigation into some of the logical properties of Dretskes account of information flow.
