This article responds to the variety of early attempts to interpret the broader significance of the violence of September 11, 2001. Its central argument concerns the grounds for political judgement. It reads a variety of current interpretations of contemporary forms of violence partly in relation to claims about a Weberian politics of responsibility and partly in relation to structural tensions between principles of multilateralism and unilateralism. Neither multilateralism nor unilateralism, the article suggests, is sufficient to engage the questions about legitimate authority and violence to which September 11, 2001 at least brought greater clarity. It concludes with a brief allusion to the increasing difficulty of drawing lines; not only lines between the civilized and the barbarian but also the physical lines that have been used to create a modern system of states, in many contexts, but this is a difficulty that is at the root of more serious problems involved in the formation of modern political judgment.
