Questionable Analogy


Questionable analogy arises when you are able to point to one or more significant differences between the two cases being compared in an analogy.  The crucial - and very worldview-dependent - question is: do the relevant differences between the two cases outweigh the relevant similarities?  If so - the analogy is weak and the conclusion is only weakly supported; if not, the analogy is (relatively) strong, and the conclusion enjoys some support.




Consider the following:

1. Amy Carter was found innocent of trespassing charges because she was just trying to explose the atrocities that the CIA supposedly perpetrates and the false advertising it engages in when not telling recruits about supposed attempts to destabilize foreign governments.
If she is found innocent by this type of logic, then Lt. Col. Oliver North should also be found innocent of any wrongdoings. He was, after all, just trying to help the people of Nicaragua gain their freedom.
If a person can plead innocence because he or she is trying to stop a larger crime from being committed, North should be given a medal.

2. Of course I don't have a problem with alcohol. I'm getting my school work done, showing up for my job on time, and doing o.k. with my boyfriend. O.k., so I have a drink or two every night -- but I just do it to relax and be social. Besides, a family friend with a heart condition was told by his doctor to have a glass of wine every day to help him relax and improve his digestion, so my drinking is just my way of staying healthy.
[Hints: the speaker here is a 19 year old female; the family friend with the heart condition is a male in his late 40's recovering from a heart attack.]

2. When asked if he would encourage the Justice Department to vigorously prosecute private citizens who illegally supplied arms and supplies to the "Contra" rebels, this official replied:

C. "Hey, it's a free country, founded on dissent."

3. It's very hard not to feel sorry for all the hungry and dying people in Africa and other countries, but I would like to know when is there going to be a song written, with all of the proceeds going to help the many people in the United States who are unemployed? Me and my family are stuck on welfare, and on the verge of losing our home and everything! So what about us?

4. Treating addiction to heroin with methadone is like treating addiction to scotch with bourbon.

[We don't treat alcoholism with alternative forms of alcohol.

[/.. We should not treat addition to heroin with methadone.

5. Until the age of viability (ca. 25/26 weeks), the fetus cannot survive outside the mother's womb. She acts like a life-support system -- one unique in all the world, for it is the only one the baby can depend upon for survival until it is ready to exist in the world on its own.

To remove the fetus from the mother's womb, with the result that it dies, is like pulling the plug on a patient's life support. The latter is murder. Therefore, the former is murder.

6. The mother is in the same relation to the fetus as a woman whose blood and kidney types may be the unique combination necessary to save an ailing person's life.

If the ailing person's family kidnaps the woman who can save that person's life, forcibly ties in her bodily systems with those of the ailing person, so as to save that person's life --

would we not say that the woman would be very nice to stay in the hospital bed for however long it took to save the ailing person's life -- but that she has no moral obligation to do so?

On the contrary, just as the kidnapped woman has every right to disconnect the tubes that tie her to the ailing person, get out of the hospital bed, and leave --

so the mother of the fetus has very right to sever her connection with the fetus, if she so chooses.

7. Education cannot prepare men and women for marriage. Trying to educate them for marriage is like trying to them to swim without allowing them to go into the water. It cannot be done.

8. Bill Clinton has no experience of serving in the military. To have Bill Clinton become president, and thus commander in chief of the armed forces of the United States, is like electing some passer-by on the street to fly the space shuttle.²
