Affirming the antecedent (modus ponens) and denying the consequent (modus tollens) are two valid forms of logical reasoning. Affirming the antecedent involves an argument of the form "If P, then Q. P is true, therefore Q is true." Denying the consequent involves an argument of the form "If P, then Q. Q is not true, therefore P is not true." These forms are foundational in deductive reasoning, ensuring the validity of conclusions drawn from given premises.
