Deleuze is one of the best thinkers of the last century, but he requires a lot of reading before what he's saying can make any sense.
It's full of quotations of works you would certainly know if you had enough culture. It feels like an violent attempt to humiliate the reader into submission. Apparently the english version came out with a lot of footnotes to provide context. This probably betrays the spirit of the original.
I'll try to listen to the podcast though, maybe some civilized people did manage to find something valuable in his writing.
