Rules in some other textbooks In propositional logic, transposition is a valid rule of replacement that permits one to switch the antecedent with the consequent of a conditional statement in a logical proof if they are also both negated.It is the inference from the truth of "A implies B" to the truth of "Not-B implies not-A", and conversely. Reflecting on the arguments in the previous chapter, we see that, intuitively speaking, some inferences are valid and some are not.
