A state of emergency, or the suspension of the legal order, which we are accustomed to consider a temporary measure, is becoming the paradigm of ordinary government everywhere in the world. Agamben’s book is a continuation of his classic “Homo sacer. Sovereign Power and Bare Life" is an attempt to analyze the causes and meaning of the evolution of the state of exception, from Hitler to Guantanamo. Moving along the “no man's land” between law and politics, Agamben step by step destroys the apologies for the state of emergency, highlighting the hidden connection between violence and law.
