In this chapter, Foucault analyzes Bentham's panopticum, an architectural construct with a central tower that observes the individual partitions built in a circle around it. The people in the cells are completely isolated from each other and cannot see the person in the watch tower. However, the observer in the tower is able to see them.Therefore, the prisoners never know if they are being watched, but are always hypervisible. As Foucault says, in the panopticum "[v]isibility is a trap." (200) The constant fear of being watched creates a correctional mechanism for the behavior of the prisoners. Foucault makes the point that this concept is not merely architectural, but deeply ingrained in modern day society. The political and social institutions set in place (specifically norms) function to order society. The fact that our behavior is seen by other people is what functions as a correctional measure that keeps people within the societal bounds. First and foremost, this societal surveillance is not inherently bad, but is necessary to structure society. However, the instituted systems can be used to oppress people society deems as non-conforming on the basis of religion, beliefs, skin color, gender, sexuality, etc. What is more, through modern technology, social surveillance penetrates deeper and deeper into private lives, raising questions about data security and privacy laws.
