Giorgio Agamben tackles our crisis-ridden world in a series of powerful philosophical essays.   “Which house is burning?” asks Giorgio Agamben. “The country where you live, or Europe, or the whole world? Perhaps the houses, the cities have already burnt down—who knows how long ago?—in a single immense blaze that we pretended not to see.” In this collection of four luminous, lyrical essays, Agamben brings his characteristic combination of philosophical acuity and poetic intensity to bear on a world in crisis. Whether surveying the burning house of our culture in the title essay, the architecture of pure exteriority in “Door and Threshold,” the language of prophecy in “Lessons in the Darkness,” or the word of the witness in “Testimony and Truth,” Agamben’s insights throw a revealing light on questions both timeless and topical. Written in dark times over the past year, and rich with the urgency of our moment, the essays in this volume also seek to show how what appears to be an impasse can, with care and attention, become the door leading to a way out.
