Crary 67: "one of the central problems confronting post-revolutionary states and other powerful interests at the start of the nineteenth century was the control and management of potentially unruly populations that had been torn out of premodern milieus and patterns of labor. A technology of power emerges that introduced dispersed methods of regulating the behavior of large numbers of people--in factories, schools, prisons, modern armies, and later in the office spaces of proliferating bureaucracies."
"places where individuals were literally confined for long periods of the day or week (or much longer, in the case of prisons) and subjected to an array of mandatory routines and procedures. They were also sites of training, of normalization, and of the accumulation of knowledge about those confined or employed"
Crary here is summarizing Foucault's idea of the "carceral continuum"
