This introduction presents an overview of key concepts discussed in the subsequent chapters of this book. The book focuses on the research on human and nonhuman animals with the expanding interest in the politics of living. It intends to trace the various ways in which the writings of Michel Foucault are being brought to bear on the issue of human-animal relations. The contributions provided are all practice-oriented, empirically grounded analyses that variously seek to create a different politics of life and living. Ranging from animals in science and industry to animals in literature and law, to explain the worlds and ways of living by means of historical, literary and ethnographic studies. Some work with a critical point of departure, but all with a curiosity that results in generous analyses that portray more-than-human politics as rich, complex, noisy and messy. The empirical specificity reveals how both human and nonhuman animal lives and their relations are constituted, stabilized or rendered precarious.
