Argument from fallacy

An argument from fallacy has the following general argument form: Thus, it is a special case of denying the antecedent where the antecedent, rather than being a proposition that is false, is an entire argument that is fallacious. A fallacious argument, just as with a false antecedent, can still have a consequent that happens to be true. The fallacy is in concluding the consequent of a fallacious argument has to be false. That the argument is fallacious only means that the argument cannot succeed in proving its consequent. But showing how one argument in a complex thesis is fallaciously reasoned does not necessarily invalidate its conclusion if that conclusion is not dependent on the fallacy. ==Examples==

Both of Bob's rebuttals are arguments from fallacy. Ginger may or may not be a cat, and Alice may or may not be English. The fact that Alice's argument was fallacious is not, in itself, proof that her conclusion is false. That one can invoke the argument from fallacy against a position does not prove one's own position either, as this would also be an argument from fallacy, as is the case in Charlie's argument. ==Further==

Argumentum ad logicam can be used as an ad hominem appeal: by impugning the opponent's credibility or good faith, it can be used to sway the audience by undermining the speaker rather than by addressing the speaker's argument. William Lycan identifies the fallacy fallacy as the fallacy "of imputing fallaciousness to a view with which one disagrees but without doing anything to show that the view rests on any error of reasoning". Unlike ordinary fallacy fallacies, which reason from an argument's fallaciousness to its conclusion's falsehood, the kind of argument Lycan has in mind treats another argument's fallaciousness as obvious without first demonstrating that any fallacy at all is present. Thus in some contexts it may be a form of begging the question, and it is also a special case of ad lapidem. ==See also==
