An Infinite Number of Monkeys
David Beaver

Many theories of presupposition fail to account for the pragmatic nature 
of presuppositional justification. An alternative account will be presented 
in which accommodation is essentially non­structural: the material
to be accommodated cannot be predicted purely by consideration of the
form of the utterance, but instead makes essential use of world­knowledge
and common­sense reasoning. The account will essentially consist of the
extension of (a reformulated version of) the Context Change Potential
(CCP) model due to Heim, Karttunen and Stalnaker, with a pragmatic module.
