Great read, LR, thanks for the link. I think "motte and bailey doctrine" is in a sense more descriptive of the precise strategy employed than the more general term "kafkatrap", although the former seems to be a special case of the latter. Orwell outlines pretty clearly the premise behind this type of approach to argument, which is the notion that undermining the ability to communicate effectively undermines the ability to think effectively. It is really not that hard to communicate effectively if both parties in a discussion wish to do so. When they can't, it seems to me that the problem most of the time is that one or both of them wants another result. The important question I ask is why someone would want to break down the collective ability to both communicate and think.
