“True, Harry didn’t go to college, but he’s a Democrat.”

People commenting on Ethics Alarms constantly accuse me of making ad hominem attacks, when what they mean to say is “You’re name-calling.” I’ll cop to name-calling. It’s can be a bad habit, but it has its uses, best illustrated when President Ronald Reagan referred to the Soviet Union as an “evil empire.” The description was true, and it immediately focused values-based criticism on a government and culture that needed it and deserved it.

Ad hominem, in contrast, is a logical fallacy in which one attempts to counter a substantive argument by attacking the character or other aspects of the advocate that can’t possibly have any bearing on the argument’s validity. For example, “you’re uglier than a pug” does nothing to disprove the substance of your adversary’s position, even if he is. Similarly, Bill Cosby has argued, even before 34 women accused him of raping them, that his advocacy of black community responsibility should not be undermined because of questions about his own rectitude.

There is nothing inherently fallacious, however, about diagnosing the conduct or statements of someone as proof that he or she is a fool, or a liar, or a jerk. It may not be civil, and it may be unfair, but it is not an ad hominem attack. As I have  explained it before, if I say you are an idiot because I think your comments are idiotic, that is a legitimate, if rebuttable assumption. (I may also be using “you are an idiot” as shorthand for “you are talking/sounding/acting like an idiot, and should avoid that.”) If I say you are an idiot, and therefor everything you say must be dismissed and ignored as the rantings of an idiot, that’s an unethical debating technique, ducking the argument by impugning the advocate.

Distinguishing between these very different but similar-appearing phenomenon can be a problem when trying to be fair to someone whose prior statements and conduct have already generated a negative diagnosis, and thus a bias. I have concluded, for example, that Joe Biden is a dolt, that Michele Bachmann is not playing with a full deck; that Sarah Palin is intellectually lazy and irresponsible, that Newt Gingrich is manipulative and untrustworthy, that Bill Maher is a pompous, none-too-bright blowhard and that Howard Dean is a vicious and unscrupulous ideologue. Nonetheless, I have to fight to assess what they say on the basis of merit, not my well-considered assumptions. It’s hard. When an idiot asserts something, is it unreasonable to be more skeptical of the statement than one would if, say, a brilliant, credentialed, unbiased observer said the same thing? (Wow—I can’t think of a single one!) No. And this is why ad hominem attacks, especially coy, subtle, clever ad hominem attacks, work so well in politics.

This brings us to that vicious and unscrupulous ideologue, Howard Dean. Continue reading →
