Chisholm II 181 ff
Negation/Frege/Simons: negative facts pose a problem here. Solution: we simply take two truth values ​​(true/false) and a function that swaps the two.
WittgensteinVsFrege: a connection should not be represented as a function. Operator N: forms a conjugate's negation from a sentence: the asserted (the used variables) are false.
Notation: x^: all values ​​of x.
Negation/Simons: negation only has the smallest range: atomic sentences.
Operator N: always negates the disjunction, never the conjunction, because of Wittgenstein’s need for atoms. Ontology: only complexes and the verbs E! and N.

Frege IV 61
Negation/denial/judgment/FregeVsKant: Kant speaks of affirmative and negative judgments. That is quite unnecessary. Even a negative judgment is a simple judgment.
>Judgment, >Sentence, >Thought.
IV 64
Negation/denial/Frege: negation is not equal to the judgments. It is not an "opposite pole" to the judgments.
IV 69
Description/subordinate clause/name/Frege: E.g. "The negation of the notion that 3 is greater than 5" - this expression refers to a specific individual thing. This individual thing is a notion. The definite article turns the entire expression into a single name, a representative of a proper name.
IV passim
Thought/Frege: to every idea belongs its negation as an independent second idea. Thoughts are not made up, but grasped. Their truth is not their being thought. They are timeless, precisely because they must always carry a determination of time with them. Thus, "today" becomes "yesterday" and "I" become "He" (two thoughts). By replacing "horse" with "mare" the thought does not change, only the coloring.

Tugendhat II 66f
Negation/Frege: negation is not a property and does not always come with the sign of negation. E.g. "Christ is immortal" is not negative per se. The negation sign applies only to the propositional content.
Proof: negation in sub clauses: only the whole sentence is asserted. In the clause (non-asserting) the "not" belongs to the propositional content from the outset.
Tugendhat II 12
Proposition/Frege/Tugendhat: negation always refers to the propositional content, not to the assertion.
>Proposition, >Propositional content.
