"Underlying [Esposito's] philosophical work is the idea that our political vocabulary is exhausted. Old political notions need not to be replaced by new ones, but through historical reflection it is important to trace what has remained unthought in those concepts . . . Esposito's reflections are most stimulating."—Walter Van Herck, <i>Bijdragen, International Journal in Philosophy and Theology</i>

"Those—especially English-speaking readers—familiar with Esposito's later research (and, in particular with <i>Bios</i>, Esposito [2008]) will find this work particularly valuable for laying out the ontological ground upon which his account of immunity and biopolitics was subsequently worked out."—Andrea Rossi, <i>In-Spire Journal of Law, Politics, and Societies</i>

"Esposito is an expansive thinker, unusually attuned to the historical as well as the philosophical dimensions of that hybrid field called 'political theory.' After a wondrous excursus on the problematic of 'community,' Esposito's challenging elaboration of community as alterity unfolds. This important and attractive translation brings to political theorists working in English Esposito's skill at speaking across the division between the analytic continental traditions." —Kirstie McClure, University of California, Los Angeles
