 If a language is used in which implication is not taken as primitive but is defined in terms of other connectives, connexive logics could also be seen as diverging from the orthodoxy of classical logic by giving a deviant account of those connectives. A definition of a connexive implication in terms of negation, conjunction, and necessity can be found in McCall 1966 and Angell 1967b. More recently, Francez (2019b) suggested the notion of “poly-connexivity” to highlight a modification of the familiar falsity conditions of conjunctions and disjunctions (in addition to adopting falsity conditions of implications as expressed by BTe′).
