Noel, See Andrew's careful explanation for a better definition, but an ad hominem argument is not about the speaker or necessarily addressed to the speaker. "Joe is a meat eater, and therefore his position on BGP is obviously incorrect" is an example, albeit an extreme one: some property is attributed to Joe that some members of the community might find unattractive and Joe's association with that property is then used as a argument against accepting Joe's view on something completely irrelevant to that property. Whether that is also a personal attack on Joe is irrelevant to the ad hominem argument. The only thing I can think of that would affect the "threshold" is the degree of relevancy between the property being asserted and the proposed conclusion. >... > On the other hand, for discussions of group governance, I > think the person's experience/knowledge/etc _are_ relevant, > because when it comes to managing human groups, there are no > 'right' answers.

It seems to me that we keep getting distracted by two things: (1) The difference between a personal attack on someone (direct or indirect) and an ad hominem argument. They actually have very little to do with each other. Certainly there are instances of the former that are not instances of the latter and vice versa. (2) The relationship between whether a question or other form of challenge to an idea is appropriate and/or politically correct in form and personal attacks. I can ask a question that is perfectly in order and phrase it with the intent that the person being asked feels personally attacked, I can ask inappropriate questions so that they are not... and the other cases exist too. > And in these latter case, I suspect there's also a grey area - > 'you're an idiot' is pretty clearly over the line, 'how much > experience have you had running large groups' is probably > relevant, and 'how old are you' (as a quick example off the > top of my head, not necessarily the greyest I could come up > with if I spent more time thinking about it) is somewhere in > the middle.. Whatever those are, they are not ad hominem arguments because there is, in non-philosopher language, no "and therefore" construction. Those are all assertions that, again, may be true or false and may or may not be appropriate in polite company whether or not they are personal attacks and regardless of their truth status. You are talking about more or less appropriate questions and statements above, not ad hominem anything. Under normal circumstances, I'd mutter something about terminology errors about a logic fallacy into my beard and move on rather than commenting on this at all. But we seem to be stepping into policy arguments about what constitutes harassment. There I think these distinctions become important because ad hominem arguments, while they reflect badly on the person who tries to make them and may reflect badly on anyone who doesn't see the logic fallacy, are rarely considered harassing even if repeated to the point of silliness. Personal attacks, whether separate or the first, "Melvin is an idiot", part of an ad hominem or other argument, are another matter entirely. And I think it is important to be clear about what we are talking about. john
