Logical negation is an operation on one logical value, typically the value of a proposition, that produces a value of true when its operand is false and a value of false when its operand is true. There is a logic called bi-intuitionistic logic, which combines elements of intuitionistic and dual intuitionistic logics. Now we want to find its negation. negations, conjunctions, disjunctions, implications, and biconditionals. Atakan Büyükoğlu Atakan Büyükoğlu.

Your question concerns a statement made in the field of classical logic. In this field of study one defines what a statement is and one defines what an implication, negation and conjunction is and thereby lays down the foundation of the theory.
And logical theories are revised on the same grounds as scientific theories are.

Logical negation is a challenge for distributional semantics, because predicates and their negations tend to occur in very similar contexts, and consequently their distributional vectors are very similar.A logical operator is something that can be used to create compound propositions from atomic propositions., lexical distributional constraints in relation to negation) is arguably so while being pervasive across languages. The weak negation ~A can be interpreted as something like it is consistent to assume that A is false because we have no proof of A. Sets the 1 bits to 0 and 1 to 0.The logical form of an argument is composed from the logical forms of its component statements or sentences.
