Perrault has devel- oped a theory of speech acts, based on Rieter's default logic, that captures the conventional as- pect; it does not, however, adequately account for certain easily observed facts about attitude revi- sion resulting from speech acts. A natural the- ory of attitude revision seems to require a method of stating pr...
