The class of abstract logics projectively generated by the class of logics defined on tetravalent modal algebras by the family of their filters is studied.

In this paper, it is proved that M4 belongs to the class of standard systems of implicative extensional propositional calculi as defined by Rasiowa (1974).

Bilattices, due to M. Ginsberg, are a family of truth-value spaces that allow elegantly for missing or conflicting information.
