I would say it is attacking the character or motives of a person who has stated an idea, rather than the idea itself. The most obvious example of this fallacy is when one debater maligns the character of another debater (e.g, "The members of the opposition are a couple of fascists!"), but this is actually not that common. A more typical manifestation of argumentum ad hominem is attacking a source of information -- for example, responding to a quotation from Richard Nixon on the subject of free trade with China by saying, "We all know Nixon was a liar and a cheat, so why should we believe anything he says?"

But saying that their message should not be heeded because at some other point in the past they had been jerks is one. Discounting a message because of a (perceived) character trait of the author is also suspect. >> These attacks on people, as opposed to discussion of what they >> said, is one of the major reasons discussion threads devolve into >> unproductive chaos.

Which is perhaps an argument for my point: we need to identify that such a post has been made. I do not see the basis for your refutation here. Also, if the rationale for the disagreement is that you are say that a trait you say I possess (mistakenly objecting to non attack as an attack) is the reason my message (we should identify and curtail attacks on people) should be discounted -- sound familiar? Hmm. > Sometimes heated complaints - but no less legitimate for all that. Complaining about the behaviours of a person might be legitimate, but not if it is put forth as the reason to discount the actual content of the message. It also is probably off topic for the thread. And in no way is it a counter argument. In all of these cases, the relevant question is not who makes the argument, but whether the argument is valid. manoj [0] http://www.csun.edu/~dgw61315/fallacies.html -- All the existing 2.0.x kernels are to buggy for 2.1.x to be the main goal. -- Alan Cox Manoj Srivastava <sriva...@debian.org> <http://www.debian.org/~srivasta/> 1024D/BF24424C print 4966 F272 D093 B493 410B 924B 21BA DABB BF24 424C -- To UNSUBSCRIBE, email to debian-project-requ...@lists.debian.org with a subject of "unsubscribe".
