Completeness, philosophy: A) Systems are complete, if all valid statements are provable. B) The question of the completeness of a description is always concerned with specific purposes of this description within the framework of a theory which applies to the described objects. It is a peculiarity in the case of particle physics that the complete description of elementary particles does not allow the differentiation of other particles of the same type. See also incompleteness, determinateness, determination, distinction, indistinguishability.

Author Item Summary Meta data
I 134
Completeness/Bigelow/Pargetter: occurs when our explicit semantics guarantees all and only the extroverted asserted theorems. That is, our semantics does not read anything into our language, which is not already there.
Definition "extroverted axiomatics"/Terminology/Bigelow/Pargetter: an axiomatics that is developed in an already existing language.
I 135
Completeness/correspondence theory/Bigelow/Pargetter: the existence of completeness proofs provides a kind of correspondence theory.
Completeness: for us, we can show that all the propositions that are true to our semantics in all possible worlds can be derived.
I 137
Definition completeness theorem/Bigelow/Pargetter: is a theorem that proves that if a proposition in a certain semantics is assuredly true, this proposition can be proved as a theorem. How can we prove this? How can we prove that each such proposition is a theorem?
Solution: we prove the contraposition of the theorem: Instead:
If a is assuredly true in semantics, a is a theorem.
We prove:
If a is not a theorem, it is not assuredly true in semantics.
We prove this by finding an interpretation according to which it is false.
