DoubleNegationIntroductionDeclaration (python class)
See also
This section presents the DoubleNegationIntroductionDeclaration python class.
This class models the declaration of the double-negation-introduction inference-rule in the target universe-of-discourse.
Punctilious users do not need to instanciate objects from this class. In effect, the UniverseOfDiscourse class exposes the double_negation_introduction property, and instanciation is automatic when the property is accessed for the first time.
