Odd as it may sound to some, I think that there is a very important connection between the ideas of Tolkein and Foucault. Tolkein's 'eye of Sauron' and Foucault's panopticon seem to me to be different expressions of the same fundamental idea. More specifically, both these thinkers seem to be suggesting that with the advent of modernity a new form of power has emerged; a form of power that is connected to war, technology and visibility.
However, I think that whereas Tolkein viewed this power as a very ancient form of power returning to haunt us, for Foucault this form of power was in philosophical terms an innovation. Also, they both differed quite markedly on how they conceived of who or what is best equipped to resist this form of power. For Tolkein, it was the little people of the shires; whereas for Foucault it was socially 'the marginalised' and the hedonistic libertines of the bohemian counter-cultures.
I wonder who was right?
