The introduction lays out the primary argument and themes of the study, provides an orientation to religion and media, and defines the three central terms: religion, network, and disconnection. Fundamental promises affiliated networks with connection—friction-free technology, social unity, a utopian present, and perfect communication—and obscured the failures of networks to be or produce those things. Religion, while fueling those very promises, also participated in the disconnections that riddled telegraph networks: negotiating and occasioning technological breakdown, structuring social life on the violence of colonialism, investing in the impossibility of utopian futures, and fomenting the fundamental failures of communication. The final section provides an account of infrastructure to supplement theories of religion and networks.
