Time is short, folks. We don’t have all day to sit around and listen to arguments and puzzle through scholastic distinctions. Perhaps for this reason, some genius has come up with a new form of refutation:
“your argument is too long; mine is better because it’s shorter”
Here’s a recent version:
The length of such bills has been an argument against health care reform since 1993. We talked about this argument (in 2009) here.
I think it’s obvious (is it not?) that the length of our arguings have no direct relation to their quality. It’s not even a pragmatic indicator. Perhaps it even goes the other way. The longer an argument, the more likely it’ll be better (or address your objections!).
Anyhoo. What to call it? Sticking the with the Latinism popular among fallacy theorists: argumentum ad argumenti longinquitatem (argument against the length of an argument). Even the name of the fallacy is long. Get it?
