(Previous work on fine-grained intentionality without Possible Worlds.) Over the past few years concentrated on reasoning with non-indicative utterances without Possible Worlds.

Background Introduction Some issues Examples of Imperatives Proposal Semantics of Imperatives Research Context: imperatives Consider how it is possible to reason with imperatives. Allow inconsistent commands without logical collapse. Focus on using a notion of a judgement . This presentation gives a overview of the approach.
