The argument from fallacy (aka argumentum ad logicam or the "fallacy fallacy") occurs when someone calls out another arguer's fallacy, then declares that arguer's position definitively wrong because of the fallacy. This overlooks that other arguments may exist for that position that are not fallacious.

In the following case, Jen commits the fallacy of argumentum ad logicam.

Alice: "Animal experimentation is wrong because it makes me feel bad to think about it."

Jen: "That's an appeal to emotion fallacy, therefore animal experimentation is not wrong after all."

Jen is correct that Alice committed the fallacy of appeal to emotion, but that does not entitle Jen to conclude altogether that Alice's position is incorrect. There may or may not be other valid arguments on Alice's side.

Here is a template for this fallacy, where:

 âŠ¨ means "validly implies"

 P is some set of premises

 C is some conclusion

1. Not P ⊨ C

2. Therefore, Not C.

This is invalid because it does not rule out there being another set of premises (other than P) that validly implies C.
