The Fallacies of Relevance

1. Argumentum ad Hominem ( Argument the Man )
The English translation for the Latin phrase, “ Argumentum ad Homimem. ” is an “ Argument against the Man or Woman,” or more accurately, “ Argument against the Person. ” Person A claims that he owns an 3 Gaisano Malls in Mindanao. (First Person ) But knowing that Person A is uneducated and have mental problems and have no documents to prove. So therefore, he didn’t own an 3 Gaisano Malls in Mindanao.

The Three Forms of Ad Hominem


The fallacy of abusive ad hominem is committed when the “second person” refutes the claim of the “first person” by verbally abusing his or her character.

My group mates suggests that lowering the fines in this coming CBAA Days will be a good idea – this is coming from a woman who eats a ice cream Big Ben’s each night!


The fallacy of circumstantial ad hominem is committed when the “second person” discusses the circumstances directly affecting the “first person” (i.e religion, profession, ethnic background, gender, age, political affiliation, etc.) instead of the argument itself.

We should disagree about the same sex marriage because after all it’s not good to see and it is not the right thing to do.


“Tu Quoque” is the Latin of “you, too.” The fallacy of ad hominem tu quoque is committed when the “second person” attempts to shit the burden of guilt back to the “first person” in the order to appear himself as a hypocrite in the sense that there is inconsistency between “what he claims” and “what does”; “what he preaches” and “what he practices.”

The Americans keeps on working everyday, therefore we can keep on working everyday too.

Poisoning the Well

abusing someone for sheer pleasure does not qualify as an example of an ad hominem fallacy.
