Sir Thomas More’s Utopia provides an occasion to delve into how fiscal policy and administrative activity constitute forms of worldmaking. This chapter argues that More’s Utopia places the challenges of defining and funding security at the center of its project, both in Book One’s critique of contemporary rule and in Book Two’s thought experiment about how to govern security. Utopia, as an alternative to contemporary Europe, can be seen as an attempt to resolve the fiscal security dilemmas besetting European governments by eliminating private property and money. The presence of other polities, though, complicates the effort to imagine a world in which security is distributed equitably, a world without fiscal conflict or the violence that monarchical wealth enables. Utopia thus provides both a powerful diagnosis of the shortcomings of contemporary governmental practice and a meditation on the limits of the ability to govern security.
