Cartesian Dreams

E:

I have been writhing - with the intention to post it here - a long essay about some of the ideas raised in the recent film Inception. In digging for some point or other that Descartes made regarding dream in his Meditation i tripped over a tidy little piece entitled, Descartes, Dreams and the Philosophy Behind Inception. It includes reference to a couple of notions i am exploring in my essay. There is much more "philosophy" i intend to draw on, hidden, perhaps unknown to itself, in that very deceptively "Hollywoodish" movie.
