Any argument that is in the form of "If" will be valid, and any argument that affirms the consequent will be invalid A valid argumentform If p, then q p Therefore, qAnargument formis said view the full answer Previous question Next questionBecause if P is false, the first two would be (vacuously) true, but it might be that also Q is true and R is false, which would make the last one false!P q p → q ∼ q ∼ p T T T F F T F F T F F T T F T → F F T T T In this case there is only one critical row to consider, and its truth value it true Hence this is a valid argument Result 22 (Generalization) Suppose p and q are statement forms Then the following arguments (called generalization) are valid p p∨q q p∨ q Result 23

It's just that, as opposed to the regular and contrapositive forms, the condition for failure is reversed On the other hand, "if not p then q" is a completely different assertion(See this post for an explanation of the conditional) Even if you have If ( P implies Q ) then ( P implies R )Therefore, the argument must be valid 5 Valid We can test for validity by substituting statement variables into the argument If we do the substitution, we get If p, then q Not q Therefore, not p Upon inspection, we find that this is one of the common patterns of valid inference discussed above—modus tollens
