I've tried to read Chomsky's linguistics and yes they are very difficult. I tried reading Rules and Representations, which was impossible for long time. I think I finally started understanding Chomsky's linguistics by reading Howard Gardners discription of his work as it applies to education and learning. Even his politics can be difficult for some people. My wife has a Phd in statistics but she claims that she can't understand a thing he writes. But to be fair to Chomsky, I think his main point about Foucault was that, even when one attempts to translate it from acedemic jargon to comon language, it was still confusing and convoluted. For me, Chomsky's work can be explained and made relevant to non-acedemic folks. But then I've never spent the time to understand Foucault's work like I have Chomsky's.
Also, Doug, do you think that theory really makes our message to the carpenter next store that more understandable? I wonder, because my exeperience with people is that they have an aversion to theory and tend to gravitate to concrete nuts and bolts thinking.
