Sokal was trying toprove that cultural studies professors haven't any rigour. This would make them look cutting-edge. As soon as his paper was published, Professor Sokal publicly exposed the whole set-up. I presume, he thinks that these European intellectuals are crucial to political action. Hall's introductory essay gives the impression of someone who is willing to use philosophical references to impress the naive.
Action is what counts.
For, if this text is 'where Lacan makes his interruption into colonial discourse theory', as Gates asserts, it is also where Fanon 'reads' Lacan in the light of his own preoccupations. In the long footnote on the 'mirror phase', it is Fanon's appropriation of Lacan which strikes us most vividly. It is difficult not to agree that he writes here as if 'the real Other' is indeed 'a fixed phenomenological point'. Fortunately, this swishy stylistic complexity is far outdone by Homi Bhabha, who sometimes does do good work, I think. However, in Read's book, Bhabha constructs sentences that are so magnificent that one has to appreciate them as ink marks on the page, as a kind of finger painting in minutiae.
