Agamben, p. 12
The protagonist of this book is bare life, that is, the life of homo sacer (sacred man), who may be killed and yet not sacrificed, and whose essential function in modern politics we intend to assert. An obscure figure of archaic Roman law, in which human life is included in the juridical order [ordinamento]1 solely in the form of its exclusion (that is, of its capacity to be killed), has thus offered the key by which not only the sacred tests of sovereignty but also the very codes of political power will unveil their mysteries. At the same time, however, this ancient meaning of the term sacer presents us with the enigma of a figure of the sacred that, before or beyond the religious, constitutes the first paradigm of the political realm of the West. The Foucauldian thesis will then have to be corrected or, at least, completed, in the sense that what characterizes modern politics is not so much the inclusion of zoē in the polis – which is, in itself, absolutely ancient – nor simply the fact that life as such becomes a principal object of the projections and calculations of State power. Instead the decisive fact is that, together with the process by which the exception everywhere becomes the rule, the realm of bare life – which is originally situated at the margins of the political order – gradually begins to coincide with the political realm, and exclusion and inclusion, outside and inside, bios and zoē, right and fact, enter into a zone of irreducible indistinction.
Everything happens as if, along with the disciplinary process by which State power makes man as a living being into its own specific object, another process is set in motion that in large measure corresponds to the birth of modern democracy, in which man as a living being presents himself no longer as an object but as the subject of political power. These processes – which in many ways oppose and (at least apparently) bitterly conflict with each other – nevertheless converge insofar as both concern the bare life of the citizen, the new biopolitical body of humanity.
