I like the fact that he is trying to create an alternative intellectual universe in which Thabo Mbeki always makes perfect sense and is really an intellectual hero. When he talks about the ways in which what we see as normal is really situated, he is rather good.
The problem is that he often argues like a little boy. For example he points out that Tony Leon (not his favourite man!) quotes Lord Acton. He then argues that Lord Acton was a dreadful man. Then this must inevitably mean in his book that Leon is also a terrible racist pig. Nee what, this is lazy reasoning of the worst kind.
