"To achieve this, it is at much too much and too little that the prisoner should be constantly observed by an inspector: too little, for what matters is that he knows himself to be observed; too much, because he has no need in fact of being so. ...Unverifiable: the inmate must never know whether he is being looked at at any one moment; but he must be sure that he may always be so." - Michel Foucault, Panopticism - Disipline & Punish (Surveiller et punir)
