Transposition is a valid argument form and rule of replacement of propositional logic that allows one to invert and then convert a material conditional. That is, if P \to Q is a material conditional that is true, then we may infer \lnot Q \to \lnot P.

This rule of replacement could be represented symbolically as: P \to Q \Leftrightarrow \lnot Q \to \lnot P, where \Leftrightarrow is a metalogical symbol meaning "can be replaced with".
