ОТРИЦАНИЕ

Negation

In materialist dialectics negation is regarded as a necessary moment of development, a condition for qualitative change of things (see Negation of the Negation, Law of).

A logical operation with the help of which a new proposition is inferred from a given proposition (so-called negation of the initial proposition). If the initial proposition was true, its negation is false, and vice versa. The negation operation is usually performed by introducing the particle "not" and at times with the help of turns like "it is wrong", "it is false". Propositions resulting from a negation operation are usually designated in logic through A, ¬A or ~ A. Negation is one of the main operations in propositional calculus and functional calculus.
