This essay examines the cultural dimensions of state administrative formation. Revisiting the organization of early U.S. state school administrations in the decades before the Civil War, I emphasize the culturally peculiar vocabularies of universal salvation and motherly care in which early administrators outlined an apparatus of state “designed, like the common blessings of heaven, to encompass all.” Self-consciously distinguishing themselves from a republican governing tradition that depended upon localities to administrate state policy, the Unitarian Horace Mann and his liberal Protestant allies imagined a unified state “like a mother … taking care of all its children.” Drawing from a cultural preoccupation with a motherly and infinitely forgiving God, these Massachusetts state administrators articulated a vision of a department of state government that would directly recognize all persons, and all schools, “within every part of the Commonwealth.” Such words were more than metaphor, though metaphor was crucial to the project. Rather, the organizational logic of the “motherly state” unfolded in the matrices of responsibility and communication, of surveillance and discipline and labor policy that constituted the foundational systems of early comprehensive state administration. By bringing together the insights of institutional development with the methods of cultural history, this essay ultimately suggests that government itself can be understood as a cultural artifact.
