Document Summary

Chapter 8: formal fallacies and fallacies of language. A fallacy, consisting of a conditional claim as one premise, a claim that affirms the consequent of the conditional as a second premise, and a claim that affirms the antecedent of the conditional as the conclusion. Example: (1) if jane is a member of a sorority then jane is female (2) jane is female. Therefore (3), jane is a member of a sorority. The structure, or form of this argument is what makes it invalid rather than its content if we switch the places of claims 2 and 3, we"d have a valid argument. P and q stand for independent clauses part of claims that are true or false. The part of the first premise after the if is the antecedent of the claim: the part after the then is the consequent.
