Situation semantics for logics consider not what is true in worlds, but what information is contained in situations.

A Reaction
Since many theoretical physicists seem to think that 'information' might be the most basic concept of a natural ontology, this proposal is obviously rather appealing. Barwise and Perry are the authors of the theory.
