I 252f
"Purely indicative" unambiguous (substitutability of identity) not: "Tullius was a Roman" is trochaic - An expression in quotation marks is not purely indicative - ambiguous reference. - Every truth function is denotation-transparent.
I 332
Sentence = Universal! - Value of the variables: Proposition (object) - remains intact even after the elimination of the singular term. - The proposition resists a change of the truth value. - The proposition remains nameless in "x0p".
I 337
Sentence: is not the class of its expressions, otherwise non-expressed sentenceswould be = zero class (all would have the same meaning). - A sentence is not a property of expressions either. - Solution: sentence as a consequence: class of pairs. - Partial sign: class of expression incidents.
I 336
Words describe - sentences do not (no singular term)! - Nevertheless, a sentence has a meaning: the singular term is formed by bracketing the sentence. (not a proposition!) - Proposition here: completion of the correct sentence to a timeless sentence - timeless sentence "The door is open": which door? denotes nothing.

Prior I 35
Sentence/Quine: is not an object - Then also no quantification, no bound variables for it - PriorVsQuine: unproblematic: E.g. "J. believes p": J. does not believe anything, this ultimately stands for a sentence.

Quine VII (f) 109ff
Sentence/QuineVsFrege: sentences must not be regarded as names and "p", "q" not as variables, accept the entities as entities named through expressions as values.

X 31
Sentence/Quine: we speak only of sentences if we want to generalize - (and we cannot do that through objects).
X 35
Semantic ascent/Quine: this mention of sentences is only a technical necessity that arises when we want to generalize in one dimension, which cannot be grasped by a variable.

XII 39
Sentence/Proposition/Propositional attitude/Translation/ChurchVsQuine: if sentence bears the meaning instead Proposition, then problem: E.g. Edwin believes the German sentence S - English Translation: a) leave sentence, b) reproduce in indirect speech in English: then both are not equivalent - "QuineVsVs: admitted, but unclear concept of everyday language equivalence.
Quine: still not accepts linguistic forms as objects of propositional attitude: too artificial.
