The concept of dependence is central both to the study of modern republicanism and to the study of systemic corruption. Recently, Lawrence Lessig has described American politics as suffering from "dependency corruption," a type of institutional corruption about which eighteenth-century republican writers were extremely worried. This article examines the use of the concept "dependence" in the current "neo-roman" republican theory stemming from Quentin Skinner, Maurizio Viroli, and particularly Philip Pettit. The article argues that the term dependence has two essentially distinct inflections, one relating to outright domination (subjection to arbitrary power) and the other relating to a condition of material subordinacy (dependency corruption). If liberty is the "the absence of dependence on the will of others," it is extremely important to determine just what independence entails. This article suggests that dependency corruption was a dominant concern of the modern republican tradition, but it is a concern that is largely ignored in today’s new republicanism. By way of a foray into the seventeenth- and eighteenth-century sources employed by the new republicans, the article attempts to revive a manner of thinking about corruption that risks being lost to view.
