Anything worth talking about, is worth blogging about

Argumentum ad Sangerum

At CNN, Ruben Navarrette Jr. has a commentary on the stimulus package recently passed by the United States House of Representatives. He makes two arguments, both of which are bad.

One of them is the fact that funding family planning is unnecessary for stimulating the economy. He somehow thinks that advocates of including contraception in the stimulus package think that “babies who would otherwise have been born were destined to become dependent on welfare and other public services”. I wonder what makes him think that every baby born will not end up that way, (that is, the assertion that all children born during a recession will end up dependent on welfare is as baseless as the assertion that none of them will). Also, including contraception in the stimulus package would have saved money, $200 million over five years to be precise. He also says that, in a paragraph of its own, “[t]here is nothing more private — that is, none of the government’s business — than the personal decision that a family makes about how many children to have. Besides, [Nancy] Pelosi’s comments had an ugly ring to them.” Rather ironic considering that contraception allows people to control the when and number of children, and that making access to it more difficult means the government is interfering in the childbearing decisions people have. By denying it to poor people, the government is making it harder for them to do that. The net result is that sex becomes an expensive luxury for the rich and dangerous for the poor.

In addition, he makes a fallacious argument by tying birth control funding to Margaret Sanger and eugenics. Margaret Sanger did indeed advocate eugenics, an evil thing, for which she is rightfully condemned. She also advocated the use of birth control. However, the fact that she advocated one evil thing has no bearing whatsoever on whether the other things she advocated were also evil because of her. To do so is to commit what is called the association fallacy. Since Sanger, her advocacy of eugenics, and the organization she founded, Planned Parenthood, are often involved in the abortion debate, and the fact that she advocated eugenics is often mentioned in an attempted to discredit the others, I feel that this act of playing the Sanger card happens often enough for me to dub it argumentum (or reductioad Sangerum. This faulty reasoning can also go in reverse, by arguing that since Sanger was opposed to something, that something must be good. As according to Wikipedia, Sanger was opposed to (some) abortion (for at least part of her life), this means that since Sanger was “evil”, and she was opposed to some abortions, this means that abortions must be “good”, right social consies? Playing the Sanger card this way can sure turn the abortion debate on its head.

As I explained the argumentum ad Sangerum is a special form of the association fallacy. The following example demonstrates why the association fallacy, and hence the argumentum ad Sangerum is fallacious: Adolf Hitler (I know about Godwin’s Law, but please bear with me) advocated and committed various hellish acts, such as anti-Semitism, genocide, mass murder, war crimes, and so on, and is rightfully considered an evil man. Hitler did not make those things evil; genocide and the others are evil in of themselves. Basically, Hitler is evil because of the things he did and advocated. To assert that something is bad just because Hitler advocated it commits what is known as the argumentum (or reductio) ad Hitlerum, which is a special form of the association fallacy. As explained above, Hitler is evil because of his actions; his actions are not evil because of him. In other words, Hitler did not make genocide and the others evil; genocide and the others were evil before him, and they are still evil now that he is dead. To assert that Hitler made his actions evil leads to ridiculous conclusions; after all, since Hitler was a vegetarian and was evil, based on this line of reasoning, other vegetarians, like Gandhi, were also evil. The absurdity of this conclusion shows that the argumentum ad Hitlerum is fallacious. The same reasoning applies to the argumentum ad Sangerum.

Of course, just because someone is committing the argumentum ad Sangerum fallacy does not mean in of itself that their conclusion is wrong; to do is to commit another fallacy, the fallacy fallacy. What they need instead is a new argument. The same logic applies to everyone else.

  1. Oh. My. God. Nothing irritates the little bitch inside me more than logical fallacies passed off as a real argument. I never did get the hang of the Latin terms for them (my Logic professor insisted these were ridiculous).

    The other problem with “Sanger advocated for it, therefore it’s bad” can be demonstrated in a simple syllogism. Assuming one is not stupid enough to believe that every single thing the woman ever did or believed was evil (you know, like sleeping at night), one can say, “Some X are evil; Y is an X; Therefore Y is evil”. It’s about as logical as “Some men are bald. Don King is a man. Therefore Don King is bald.”

    By the way, thanks for adding my blog to your roll. 🙂
