This volume constitutes the largest collection of writings by the Italian philosopher Giorgio Agamben hitherto published in any language. With one exception, the fifteen essays, which reflect the wide range of the author s interests, appear in English for the first time. The essays consider figures in the history of philosophy (such as Plato, Plotinus, Spinoza, and Hegel) and twentieth-century thought (most notably Walter Benjamin, but also Heidegger, Derrida, Deleuze, the historian Aby Warburg, and the linguist J.-C. Milner). They also examine several general topics that have always been of central concern to Agamben: the relation of linguistic and metaphysical categories; messianism in Islamic, Jewish, and Christian theology; and the state and future of contemporary politics. Despite the diversity of the texts collected here, they show a consistent concern for a set of overriding philosophical themes concerning language, history, and potentiality.
