You are quite right Iorek re shite grasp of all of this ... stuff - stuff that used to be in accessible parts of my brain. Now - poof!- there is nothing.
Though I do think that F was broadly right in his idea that the Panopticon was the model not only for the 'modern' prison but for modern society. The extent to which we have internalized the Gaze at the centre (the gaze of the guard who may, or may not be there, in B's panopticon) is both remarkable and remarkably effective. With, or without, the actual forms of surveillance which exist in our culture.
and I think it's also true that we are more afraid of the absence of the gaze now, than of its presence. Which is why so much of culture now could be boiled down to 'look at me!'. From reality TV, sleb cutlure etc to ..erm, the web.
MN could be said, in fact, to be a perfectly functioning unit of self-surveillance, with each of us acting as the surveillor of all the others, to create a self-disciplining and regulating and therefore docile body of 'individuals'. At the centre there is both something, and nothing.
