Abstract

The author examines Scheffler’s extensional alternative to the usual notion of belief and shows that it is necessarily inadequate to serve the purpose for which it was designed. This point is established by showing that Scheffler’s proposed substitute for psychologically intensional verbs like ‘believes’ can not deliver philosophers from the classical puzzles over propositional attitudes and can not be used in all cases even to provide materially equivalent extensional substitutes for ordinary belief-statements.
