FREGE - SENSE MEDIATION
Project:
LOGICISM: Arithmetic can be redefined in strictly logical terms. Axiom regarding predicates definable in terms of class proves to generate a contradictory class.
PROBLEM OF IDENTITY:
LING EXP SENSE REFERENT
Singular terms (least restrictive) sense Objects
Sentences thought The True/the False
Predicates concept Truth Function
Logical Constant ? Truth Functions
SOLUTION TO VACUITY:
Sense: described as the manner in which a referent is picked out. Public, objective.
Introduced to solve VAC: introduces source of meaningful difference in cases of non-trivial identity. Does it explain MER? Are the meaning of sentences containing empty referents explained by having a sense but no referent? IF we allow that terms may be meaningful by virtue of having a sense but no reference, then does reference fall out of the picture? I'm sure this is covered somewhere.
LEAVES UNITY UNACCOUNTED FOR:
Frege seems to provide a solution to the unity of the sentence grounded in an objective, non-actual entity: false sentences have such a referent - the false. However it is unclear how explanatory that this can be, since all false (or true) sentences end up with the same reference. His account of thoughts will have to do the work here instead.
