I'm non-plussed that anyne should fail to notice that Althusser's arcane language is largely a mask for his dishonest and often feeble thinking. There is a world of difference between Einstein's General Theory and Reading Capital - the one is right, and the other wrong. Althusser's cranky preoccupation with categories is a consequence of his own formalism. It seems entirely unsurprising that somebody should pick up on the fact. And since Althusser admitted in his autobiography to being an ill-read fraud, I don't really understand why anyone should want to leap to his defence.
(And incidentally, it is also patently clear from The Future Lasts a Long Time, that Althusser killed his wife because he could not bear the fact that she knew that he had betrayed the students and workers in May 68 and would not let him forget about it. So quite why it should be the case that Alan Sokal and Jean Bricmont should be denounced as reactionaries for attacking Althusser beats me.) -- Jim heartfield
