Technologies of transcendence are easily misused. Those same techniques of suspension and feats of collective will can be used to give a moral character to a range of rules and exclusions. Governance is not abolished, but rather placed in parentheses indefinitely, and rule by force or fiat takes hold: Black sites, Guantánamo Bay, prisons and county jails, ICE detention centers all rely on a state of exception, the same suspension of the normal rules of society that sacred spaces also evoke. All places, sacred and profane, depend on technology to define their boundaries and functions. This week we present essays on these spaces, and how various technologies enable them, their sense of localness, specificity, exceptionality, and transcendence.
