| Opacity, philosophy: also opacity of the reference. A problem with propositions (meanings of uttered sentences related to a speaker) is that one cannot be certain that one knows what an utterance refers to. E.g. in an empty room is a blackboard with the inscription "I am hungry". See also intensions, propositions, propositional attitudes, reference, inscrutability, quotation._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.
