Sentences 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): consists of sense components, not of objects. (>FregeVsRussell)
Subordinate clauses that begin with "that" (that-sentence, >opaque context, >propositional attitudes) have as meaning a thought, 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 get no sentence.
I 7
Sentence/Frege: 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: problem with sentences without truth value (neither true nor false, not an object, etc.).
Stuhlmann-Laeisz II 68
Sentence/Frege: except the idea (what can be t/f) there are two other aspects: a) "content" - b) "imagination".
Tugendhat II 243
Oblique Meaning//German Original: "odd"/Frege: name of a sentence. - Complex sentences: truth functions of their subsets - where that is not the case, subsets appear as names (oblique ("odd") meaning, Quote) - Nominalized Subset/Frege: 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.
