This article argues that the contributions of the Czech philosopher, Jan Patočka, have been overlooked in the study of International Relations (IR), and more generally international political theory. Attention here is drawn to the many distinctive ideas particular to Patočkian philosophy, such as the solidarity of the shaken and the care of the soul, which combine accounts of a Central European philosophy and dissident political reactions to totalitarian rule. The legacy of Patočka's work frames the latter part of the article, which examines Central European identity and 'samizdat' as often neglected reference points in IR. The article concludes by drawing these themes together in an account of rupture, inspired by the solidarity of the shaken and care for the soul.
