C&M
Over at Tech Central Station (what, it's not on my blog roll? Look again!), Arnold Kling
identifies discoursive argument types and classifies two:
Type C arguments are about the consequences of policies. Type M arguments are about the alleged motives of individuals who advocate policies.
He then proceeds to cudgel Paul Krugman in particular, but he's cudgeled the nail right on the head.
The good old fashioned
argument from authority. It used to be that to wield this particular logical fallacy, you had to say something was true because someone reputable said it was true. Of course, because many of the people who use the new version are also against authority, they've perverted this standby. It's no longer
true because a particular authority says it, it's now
untrue because someone said it.
Look on the bright side, though. The
ad homenim never goes out of style.
