"He is the object of information, never a subject in
communication"
Foucault points out. The
Panopticon's power was "visible and unverifiable"
— that is, the inmate could not see the inspector, only the looming
tower: he would never know when he was actually under surveillance.
This uncertainty, along with the inmate's isolation and loss
of privacy, is the means of his compliance and subordination.
Uncertainty becomes the principle of his own subjection. It assures
that, in Foucault words: "surveillance is permanent in its
effects, even if discontinuous in its action". And thus
Foucault draws our attention to our own very modern condition, locked
within: "a state of conscious and permanent visibility that
assures the automatic functioning of power".
