] | This is a pretty confusing question to ask early in one’s logical education! What’s going on is that, if we want to think about the statement “$p$ implies $q$” and we can prove that the converse “$q$ implies $p$” is false, then in fact we know that $q$ is true and $p$ is false, which means $p$ does imply $q$. That is, ... | If you translate $[A \implies B]~~$ to $~~[(\neg A) \vee B]~~$ then the assertion that (in general) $~~(P \implies Q)~~$ must hold when $~~\neg(Q \implies P)~~$ ::: is a **true assertion**, demonstrated as follows:
The only way that the statement $(Q \implies P)$ can be false is if
$$(\neg P) \wedge Q.\tag1$$
