Ad Hominem Fallacy: Definition & Examples

Click For Summary
The discussion centers around the distinction between insults and ad hominem attacks. An ad hominem is defined as an attempt to discredit someone based on irrelevant personal characteristics, while mere insults do not qualify as such. Examples of ad hominem attacks include statements that imply a person's personal issues undermine their arguments, like calling someone's political views meaningless because they are an alcoholic. In contrast, straightforward insults, such as calling someone a "moron," do not attempt to engage with the argument itself and are simply abusive remarks.Participants emphasize that many people misinterpret insults as ad hominem attacks, which can lead to confusion in discussions. The conversation also touches on the nature of logical fallacies, noting that while ad hominem attacks can be seen as a type of non sequitur, they specifically involve a personal attack that is irrelevant to the argument being made. The discussion concludes with the idea that understanding these distinctions is crucial for maintaining clarity in debates and discussions.

People ought to read what this actually consists of, because I've noticed people mistaking mere insults for Ad Hominems.

http://en.wikipedia.org/wiki/Ad_hominem

Calling someone an insulting or abusive name is not an Ad Hominem. Generally, an Ad Hominem is an attempt to discredit someone based on something about them that is actually unrelated to the issue at hand. These are Ad Hominems:

"Joe's political views are meaningless: he's an alcoholic."

"Don't let Sam correct your grammar, he believes in Ancient Aliens."

"It figures Thelma got sexually assaulted: she's been divorced twice and never goes to church."



These following are not Ad Hominems, just insults:

"Frank is a moron, and ugly on top of it."

"She is nuts."

"Edna is an ignorant hack."

"You'd have to be crazy not to like Ed Smith."

...verbal abuse in the absence of an argument is neither ad hominem nor a fallacy.

Therefore:

"You don't vote Republican? You're an idiot!"

Is not an Ad Hominem, just an insult. It might take place during the course of an argument, but it is not, itself, an argument of any sort.

So when not completely sure of an insult, or a witty retort back, someone will say " I think I just got insulted! ".
With an Ad Hominem can one say " I think I just got Ad Hominemized !"
 
Interesting that you start this thread Zooby, It's one of the roots of my enemy thread. Exactly that.

I don't exactly follow. I was actually prompted by seeing someone in another forum misinterpret an insult (a pretty mild one, if it was one at all) as an Ad Hominem.

And another: "Ignore zooby's analysis of ad homs. Just one look at his avatar and you know he has to be wrong." :-p

How about this: "You're just jealous because I know how to spell out my full name." Ad Hominem?

That is just an insult; your argument in the opening post is correct. Had you used my incomplete spelling as a reason for dismissing my claim, then that would have been an ad hominem attack.
 
I try to avoid using Ad Hominem attacks. I might point out that Zoobyshoe is a stupid, ugly, fat, ignorant slob. But I would never give that as the reason that he is always wrong.

Whether zoobyshoe is ugly or fat is irrelevant to the correctness / incorrectness of his posts. That is what would make the use of these terms an ad hominem attack.

Very good. Likewise, I would never allude to the fact you both are impossibly hideous, near-reptilian monstrosities, to explain why your utterances are invariably nonsensical and incoherent. It would be an Ad Hominem to do so, because the former has nothing to do with the latter.

I disagree with this zoob - often the other half is just left insaid, for the reader to fill in.

I guess, it doesn't need to be said that this thread is all about apophasis.

So, in your example, if you use your insult to refute their statement, it is a logical fallacy (ad hom.), but if you deduce an insult from their statement (eg. you do not support Republicans, ergo you're an idiot.), then it is not a fallacious argument?!

Call it what you want, but I still think the latter is fallacious argument. Maybe a non sequitur, but still fallacy.

Hairsplitting? :-p

hrm, interestingly, according to wiki, an ad hominem is considered an informal fallacy and nonsequitor is considered a formal fallacy.
 
  • #18
I do see one common use of the ad homimem retort that is abused. A poster submits a link to an obscure or hopelessly biased reference that has no hint of rigorous or scholarly analysis of the subject at hand. If in response one declines to read or respond to the reference then the ad hominem retort is often tossed out, incorrectly since there is no argument at hand from the reference.

If you can tell that is what is happening, you know which it is. My point is simply that an insult is not an Ad Hominem fallacy, that they're two separate things.

P1: define insult functionally
P2: demonstrate that target participates in abnormality of function defined in P1
C: therefore, person fits definition of insult

viola! Look, we can make valid insults!

It's not just a non-sequitor. It draws a false connection between one thing and another, implying that one thing causes the other. "Don't listen to Joe's political opinions, he's an alcoholic." His being an alcoholic does not necessarily have any bearing on his political views, but the Ad Hominem asserts that it does.

And that's exactly what a non-sequitur is.

I suppose that every logical fallacy has a non sequitur in it somewhere. If so, then it doesn't shed any light on the subject to note that Ad Hominem fallicies are also non sequiturs.

The latter is a "bald assertion", an assertion made with no attempt to back it up or argue for its correctness. Therefore, it is not a fallacious argument because no attempt to make an argument is present. It is just an insult. The abusive label "idiot" may not actually apply to the person in any way, but that doesn't make it a logical fallacy. The formal logical fallacies have specific definitions, and this is about maintaining some rigor in understanding, and sticking to, those definitions, so that our logic is sound.

Using an insult to try to discredit someone's views would also not be an Ad Hominem: "You don't vote Republican because you're an idiot!" is still just an insult, an abusive remark.

The Ad Hominem that might arise here would be something like: "I'm not surprised you don't vote Republican. Your grades in school were consistently below average, and IIRC your I.Q. score was about 75." Here there's an attempt to argue that the person's party preferences are of no merit by falsely implying a correlation between his intelligence and his voting preference. It's an Ad Hominem fallacy.

If we say to someone who can be said to be of low intelligence by objective standards (low I.Q. score), "You don't vote Republican because you're an idiot!", then what we have is probably BOTH an Ad Hominem and an insult, the latter being because their level of intelligence is referred to abusively.

If I may that's a bit off the mark. Listening to Joe's opinion and then asserting he's wrong because he is an alchoholic is indeed textbook ad hominem. However, this is not: I decline to take time to listen to Joe's opinion because I know he's intoxicated, though he *may* indeed be right, but it is more likely that he's incoherent and there is only so much time in the day.

JUST a non-sequitor:" I'm very tired today. That girl is wearing a green dress." No Ad Hominem here.

An Ad Hominem is more than just a non-sequitor.

I'm not sure i see your point. Can you clarify it?

Ad hominem refers to argument by attack on the presenter of the argument. Refusal to listen is not ad hominem, as there is no argument. This forum runs on similar lines: not all and every opinion from the web can be posted here. Those limitations are not ad hominem attacks on, say, crackpot references which are banned.
