 Subordinate ends are also evident in the design and management of the panopticon prison: security and economy are foremost, but tempered by humanity and accountability. Impressed by the dynamic of its circular architecture which allowed the warden, obscured from view in the shuttered watchtower, to observe the activities of prisoners day and night, Michel Foucault took the perspective that “panopticism” defined a “new physics of power”, an experimental “laboratory of power” in which behaviour could be modified, and he viewed the panopticon—that “cruel, ingenious cage”—as a symbol of the repressive, disciplinary society, the modern “society of surveillance” (Foucault 208). This view of the panopticon has opened up some interesting lines of discourse on the encroaching methods of control and surveillance in contemporary liberal societies (Brunon-Ernst 2012). However, as a critique of Bentham’s proposals it hardly does justice to the intricacies of the project, as Semple (1993) has shown.
