ABSTRACT Terrorism is perhaps the greatest challenge of the contemporary age. Of all the canonical figures in political theory, Thomas Hobbes is the most likely candidate to offer genuine insight into this problem. Yet although his analysis of the state of nature is immediately relevant to the diagnosis of this problem, his metaphysics cannot sustain his politics. His aspiration to “immutable” natural laws grounded in the universal motivation of the fear of death crumble when this fear is no longer universal. (...) When terrorists are inspired by a religious ideology that makes them willing to die for their beliefs—and when they benefit from other asymmetries with the civilian populations against which they are arrayed—Hobbes the theorist of war and international relations becomes less relevant than Hobbes the prescriber of “rational” (fearfully pacific) human nature.
