Norm-
Sorry that this time of the year has us so busy with holidays and work commitments, as I did not have an opportunity to reply to this question of yours within the discussion's established timeline.
That may be an extended element of critical theory in itself!
I recall the first time I encountered critical theory, which is something that is easier to dismiss depending on one's experiences within a cultural majority (or at least believing oneself to be). I then started to notice how there may be something to this in the work of he Brazilian educator Paulo Freire (who you did not mention), after which I then went back to Marcuse, Gramsci, et al. The work of Habermas never quite excited me, though I think we get to the same place when you explained (p. 177) "ideology critique is about asking questions of things that are otherwise considered too self-evident to be put into question" (which is exactly the first step for me (personally) into postmodernism; though others seem to keep these nicely separate).
From this perspective, I wish we were able to discuss the myth of the "knowledge economy" that you talk about in your text. I think about this and those who engage in this as "knowledge workers," and wish we has more time to flesh this out a bit (and while SCoPE here remains open, you probably have other commitments).
Can you perhaps offer some suggestions for further reading and research in this area, especial for those of us within an eLearning framework?
Thank you.
Jeffrey
