II 48
Truth Value/Frege: a truth value cannot be part of a thought any more than the sun, because it is not a sense but an object (truth value = object).
II 51
Sentence/Frege/(s): a sentence consists of sense components, not of objects. (>
FregeVsRussell)
Subordinate clauses that begin with "that" (>
that-sentence, >
opaque contexts, >
propositional attitudes) have a thought as meaning, not a truth value.
II 74
Sentence: the idea itself does not yet determine what is to be regarded as the subject (>
Ramsey). We must never forget that different sentences can express the same idea.
Neither is it impossible that the same thought appears in a decomposition as a singular one, in another one as a particular one, and in a third one as general one.
II 77
Sentence: the three proper names: "the number 2", "the concept prime number", "the relation of the falling of an object under a concept" behave as brittle to each other as the first two alone: no matter how we group them together, we do not get a sentence.

I 7
Sentence/Frege: a sentence does not represent a proposition (only a that-sentence does that, a subset) but for a truth value. There is a sentence for each proposition that expresses it and that states the truth conditions. Vs: there is a problem with sentences without truth value (neither true nor false, not an object, etc.).

Stuhlmann-Laeisz II 68
Sentence/Frege: except for the idea (what can be true/false) there are two other aspects:
a) "content"
b) "imagination".
>
Content, >
Imagination.

Tugendhat II 243
Oblique Meaning/German Original: "odd"/Frege: the oblique meaning is the name of a sentence. Complex sentences: have truth functions of their subsets - where that is not the case, subsets appear as names (oblique ("odd") meaning, Quote). Nominalized Subset/Frege: a nominalized subset is only part of a thought. TugendhatVsFrege: such a subset cannot be replaced, so the truth-value potential cannot consist in its truth value.
Tugendhat II 245
Sentence/Frege/Tugendhat: since all sentences are derived from the subject-predicate form, subsets must sometimes be nominalized. Exception: causal and conditional clauses.
