Semantic Value/Schiffer: E.g. "Snow" refers to the stuff snow - "is white" is true of every white thing. - "not" expresses the negation - ((s): negation is the semantic value of "not") - ((s) semantic value can be the extension (of predicates)) - the truth function (of logical constants) - or the reference (of a singular term). - Schiffer: they play their role in determining the truth conditions - then the semantic sense (not value) is determined by the conceptual role: conceptual role/Schiffer: is an abstraction from the functional role: to know the functional role of a neural sentence means knowing the functional role of belief of s (or to wish that s, etc.) - subsentential: to know the contribution of this role to the conceptual role of the whole sentence. - E.g. if you believe that s, then you do not believe [not-s] etc. - Problem: the semantic sense is not always determined by the conceptual role. - conceptual role: is in the head. - twin earth: the twin has the same conceptual role. - On the other hand: semantic sense of predicates is surely causal - even with general term.
