A revelatory account of how water has shaped the course of human life and history, and a positive vision of what the future can hold—if we act now From the very creation of the planet billions of years ago to the present day, water has always been central to existence on Earth. And since long before the legendary Great Flood, it has been a defining force in the story of humanity. In The Three Ages of Water, Peter Gleick guides us through the long, fraught history of our relationship to this precious resource. Water has shaped civilizations and empires, and driven centuries of advances in science and technology—from agriculture to aqueducts, steam power to space exploration—and progress in health and medicine. But the achievements that have propelled humanity forward also brought consequences, including unsustainable water use, ecological destruction, and global climate change, that now threaten to send us into a new dark age. We must change our ways, and quickly, to usher in a new age of water for the benefit of everyone. Drawing from the lessons of our past, Gleick charts a visionary path toward a sustainable future for water and the planet.

One of Europe's leading philosophers, Roberto Esposito has produced a considerable body of work that continues to have a significant impact on political science, sociology, literature, and philosophy. This volume offers both a comprehensive introduction to and critical explanation of Esposito's political thought and key concepts from his oeuvre. The contributors address aspects of his growing corpus such as the impolitical, community, immunity, the impersonal, affirmative biopolitics, justice, life, the third person, and the body. In addition, they highlight Esposito's reading and interpretation of classical political thinkers, including Hobbes, Machiavelli, Vico, Arendt, and Kant. The book explores applications of Esposito's philosophy to issues in international relations, post-colonialism, literature, science, technology, and philosophical and artistic practice, bringing Esposito into dialogue with important social-political concerns.

Elizabeth Sears here combines rich visual material and textual evidence to reveal the sophistication, warmth, and humor of medieval speculations about the ages of man. Medieval artists illustrated this theme, establishing the convention that each of life's phases in turn was to be represented by the figure of a man (or, rarely, a woman) who revealed his age through size, posture, gesture, and attribute. But in selectiing the number of ages to be depicted--three, four, five, six, seven, ten, or twelve--and in determining the contexts in which the cycles should appear, painters and sculptors were heirs to longstanding intellectual tradtions. Ideas promulgated by ancient and medieval natural historians, physicians, and astrologers, and by biblical exegetes and popular moralists, receive detailed treatment in this wide-ranging study. Professor Sears traces the diffusion of well-established schemes of age division from the seclusion of the early medieval schools into wider circles in the later Middle Ages and examines the increasing use of the theme as a structure of edifying discourse, both in art and literature. Elizabeth Sears is Assistant Professor of Art History at Princeton University. Originally published in 1986.
