In par- ticular, it precludes the principled generation of appropriate responses to queries that arise from invalid plans. I describe a model of P1 that abandons this assumption. It rests on an analysis of plans as mental phenomena. Judgements that a plan is invalid are associated with particular discrepancies be- tween the beliefs that the observer ascribes to the actor when the former believes that the latter has some plan, a...
