We are in a generalized crisis in relation to all the environments of enclosure—prison, hospital, factory, school, family. The family is an "interior," in crisis like all other interiors—scholarly, professional, etc. The administrations in charge never cease announcing supposedly necessary reforms: to reform schools, to reform industries, hospitals, the armed forces, prisons. But everyone knows that these institutions are finished, whatever the length of their expiration periods. ... These are the societies of control, which are in the process of replacing disciplinary societies. … There is no need to fear or hope, but only to look for new weapons. ("Postscript" 178)
In "Postscript on Control Societies," Gilles Deleuze contrasts MIchel Foucault's disciplinary societies and their reliance on confinement with control societies that use "free-floating control" to govern ("Postscript" 178). In his discussion he highlights five important institutions of confinement—prison, hospital, factory, school, and family—that are threatened as control societies emerge.
