Modus tollens is a deductively valid argument form, which means if the premises are true, the conclusion must also be true. It is used to reason from the falsity of the consequent to the falsity of the antecedent, not to establish a true hypothesis but to show that if the consequent is false, then the antecedent must also be false.
