Luke Collison is a recent PhD Graduate from the Centre for Research in Modern European Philosophy, Kingston University London. Cillian Ó Fathaigh is Assistant Professor and Marie Skłodowska-Curie Actions Fellow in Philosophy at the Jagiellonian University, Poland. Prior to that, he was a Lecturer at King’s College London and a Postdoctoral Research Fellow at Universidad Complutense de Madrid. He previously completed his PhD at the University of Cambridge, where he was a Bill & Melinda Gates Foundation Scholar. He currently works at the intersection of political philosophy, European philosophy, and the philosophy of the digital, with a particular focus on the concept of institutions. His work has been published in prestigious international journals, including Philosophy and Social Criticism; Journal of Medicine and Philosophy; Angelaki; Paragraph; and Derrida Today. He is co-editor of Subjective Agency and Poststructuralism (Routledge, 2025—with Gavin Rae); and Derrida’s Politics of Friendship: Amity and Enmity (Edinburgh University Press, 2022—with Luke Collison and Georgios Tsagdis). Georgios Tsagdis is Lecturer in Philosophy at Leiden University and a Lecturer at the Architectural Association.

The Politics of Friendship has never been more relevant at a time when being a friend seems undermined by fragmentation and a fantasy of individualism. The editors have brought together some of the most important Derrida scholars in this volume to develop critical discussions of this rich text and to remind us why we must return to it again and again.
