A fallacious argument, just as with a false antecedent, can still have a consequent that happens to be true.
[6] 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.
The fact that Alice's argument was fallacious is not, in itself, proof that her conclusion is false.
Charlie: Bob's argument that Ginger is not a cat is fallacious.
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.
Thus in some contexts it may be a form of begging the question,[7] and it is also a special case of ad lapidem.
