 Another motivation for connexive logic from the perspective of conditional logic has been presented by John Cantwell (2008) without noting that the introduced propositional logic is a system of connexive logic. Cantwell considers the denial of indicative conditionals in natural language and argues that the denial of, say, the conditional ‘If Oswald didn’t kill Kennedy, Jack Ruby did.’ amounts to the assertion that if Oswald didn’t shoot Kennedy then neither did Jack Ruby. This suggests that (A → ~B) is semantically equivalent with ~(A → B). Also Claudio Pizzi’s work on logics of consequential implication has been motivated in the context of conditional logic, see Pizzi 1977 and section 5.
