Negation Chisholm II 181 ff
Negation/Frege/Simons: Problem: negative facts - Solution: simply two truth values ​​(t/f) and a function that swaps the two - WittgensteinVsFrege: connection should not be represented as a function - Operator N: forms a conjugates negation from a sentence: the asserted (the used variables) is false - Notation: x^: all values ​​of x. - Negation/Simons: 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: he speaks of affirmative and negative judgments. - That’s quite unnecessary - even a negative one judgment is a simple judgment.
IV 64
Negation/Denial/Frege: is not equal to the judgments. - It is not an "opposite pole" to the judgments.
IV 69
Description/Subordinate Clause/Subset/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 denial as an independent second idea. - Thoughts are not made up, but composed. - Their truth is not their being thought. - They are timeless, precisely because they must always carry a determination of time with them. - Thus, "today", "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: not a property - not always 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 subsets: only the whole sentence is asserted. - In the subset (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 the assertion.
