Radio Logic


I was listening to NPR on my drive home today, and there was a story concerning a community that has been attempting to rebuild after Superstorm Sandy.  I don’t remember the specifics, but that’s beside the point.  During an interview, one community member made the following comment in regards to why they were helping out:

“If this had happened anywhere else, I wouldn’t be here.”

My initial knee-jerk reaction was to point out that, admirable as the sentiment is, this is a fallacious comment.  In my mind, I assumed the rest of the “argument” was implied to go as follows:

1.  If this had happened anywhere else, I wouldn’t be here.
2.  It did not happen anywhere else. (It happened here.)
C:  Therefore, I am here. (DN)

This looks like a clear example of the Fallacy of Denying the Antecedent.  However, upon giving it a bit more thought, I noticed that it could be understood differently:

1.  If this had happened anywhere else, I wouldn’t be here.
2.  I am here.  (DN – I’m not not here)
C:  Therefore, it must not have happened anywhere else.

This actually works, although it seems a bit stranger.  More than likely the comment was not actually meant as an argument at all, so much as an explanation.  But this is what Logic class will do to you.

  1. More charitably, the speaker seems to be saying that he would not be on a disaster site had it occurred elsewhere -- he's helping out in New Jersey because it's near his home, not Pakistan. Honest it may be, but it's an odd thing to admit.

  2. Of course, the statement contains only an implication (a conditional statement), not an inference, so your reconstruction of the (alleged) intended argument relies heavily on premises you supply.

  3. Honestly I've been doing this so much because of logic. I keep pulling apart different things that sound like arguments and claims. It's actually really helpful and I guess it means logic is actually making sense. Thanks for sharing!
