One of Europe's leading philosophers, Roberto Esposito has produced a considerable body of work that continues to have a significant impact on political science, sociology, literature, and philosophy. This volume offers both a comprehensive introduction to and critical explanation of Esposito's political thought and key concepts from his oeuvre. The contributors address aspects of his growing corpus such as the impolitical, community, immunity, the impersonal, affirmative biopolitics, justice, life, the third person, and the body. In addition, they highlight Esposito's reading and interpretation of classical political thinkers, including Hobbes, Machiavelli, Vico, Arendt, and Kant. The book explores applications of Esposito's philosophy to issues in international relations, post-colonialism, literature, science, technology, and philosophical and artistic practice, bringing Esposito into dialogue with important social-political concerns.
