My head, Michel Foucault

"My head, for example, my head: what a strange cavern that opens onto the external world with two windows. Two openings -I am sure of it, because I see them in the mirror, and also because I can close one or the other separately. And yet, there is really only one opening- since what I see facing me is only one continuous landscape, without partition or gap."

Michel Foucault, "Le corps utopique" (1966)
