Jim, I never said the Sokal article did not have any meaning. Maybe it ha= d. But the editors apparently accepted the piece because of a meaning which did not exist. Surely Sokal did not write a really good, meaningful and interesting article by pure chance? Also, the point of his article was, I= think, not so much the meaninglessness of words like `Lacanian', but the meaninglessness of some philosophers' use of physical and mathematical metaphors and concepts. I read some fragments of the kind parodied by Sokal, and they were really horrible. I am a mathematician myself and kno= w something of physics. The way these 'philosophers' abuse mathematics feel= s like when someone carelessly throws a beautiful piece of carved wood in t= he fire because he feels a little cold. Paul Janse
