In this sequel to The Scientist as Rebel (2006), Freeman Dyson—whom The Times of London calls “one of the world’s most original minds”—celebrates openness to unconventional ideas and “the spirit of joyful dreaming” in which he believes that science should be pursued. Throughout these essays, which range from the creation of the Royal Society in the seventeenth century to the scientific inquiries of the Romantic generation to recent books by Daniel Kahneman and Malcolm Gladwell, he seeks to “break down the barriers that separate science from other sources of human wisdom.” Dyson discusses twentieth-century giants of physics such as Richard Feynman, J. Robert Oppenheimer, Paul Dirac, and Steven Weinberg, many of whom he knew personally, as well as Winston Churchill’s pursuit of nuclear weapons for Britain and Wernher von Braun’s pursuit of rockets for space travel. And he takes a provocative, often politically incorrect approach to some of today’s most controversial scientific issues: global warming, the current calculations of which he thinks are probably wrong; the future of biotechnology, which he expects to dominate our lives in the next half-century as the tools to design new living creatures become available to everyone; and the flood of information in the digital age. Dyson offers fresh perspectives on the history, the philosophy, and the practice of scientific inquiry—and even on the blunders, the wild guesses and wrong theories that are also part of our struggle to understand the wonders of the natural world.

In Mexico’s Sierra Norte de Puebla, beliefs that were held before the coming of Europeans continue to guide the lives of modern Aztecs. For residents of San Martín Zinacapan, life in and on the earth is animated by the same forces, through which people seek to maintain a cohesive view of the relationship of mankind, the cosmos, and the natural world. This delicate balance of the human spirit maintains the health and well-being of villagers, and is an essential part of the social and ideological framework that makes a person’s life whole. This book describes the basic elements of a belief system that has survived the onslaught of Catholicism, colonialism, and the modern world. Timothy Knab has spent thirty years working in this area of Mexico, learning of the Most Holy Earth and following what its people there call "the good path." He was initiated as a dreamer, learned the prayers and techniques for curing maladies of the human soul, and from his long association with the Sanmartinos has constructed a thorough account of their beliefs and practices. Learning to recount dreams, forming a dreamtale, and "carrying it on one’s back" to the waking world is the first part of the practitioner’s labor in curing. But dreamtales are shown to be more than parables in this world, for they embody the ethos and cosmovision that link Sanmartinos with their traditions and the Most Holy Earth. Building on this background, Knab describes how the open-ended interpretation of dreams is the practitioner’s primary instrument for restoring a client’s soul to its proper equilibrium, thus providing a practical approach to finding and resolving everyday problems. Many anthropologists hold that such beliefs have long since disappeared into the nebulous past, but in San Martín they remain alive and well. The underworld of the ancestors, talocan or Tlalocan for the Aztecs, is still a vital part of everyday life for the people of the Sierra Norte de Puebla. The Dialogue of Earth and Sky is an important record of a culture that has maintained a precolumbian cosmovision for nearly 500 years, revealing that this system is as resonant today with the ethos of Mesoamerican peoples as it was for their ancestors.

33 essays on the fads and fantasies of science and scientists—including climate prediction, genetic engineering, space colonization, and paranormal phenomena—by “the iconoclastic physicist who has become one of science’s most eloquent interpreters” (New York Times) “Provocative, touching, and always surprising.” —Wired Magazine From Galileo to today’s amateur astronomers, scientists have been rebels, writes Freeman Dyson. Like artists and poets, they are free spirits who resist the restrictions their cultures impose on them. In their pursuit of nature’s truths, they are guided as much by imagination as by reason, and their greatest theories have the uniqueness and beauty of great works of art. Dyson argues that the best way to understand science is by understanding those who practice it. He tells stories of scientists at work, ranging from Isaac Newton’s absorption in physics, alchemy, theology, and politics, to Ernest Rutherford’s discovery of the structure of the atom, to Albert Einstein’s stubborn hostility to the idea of black holes. His descriptions of brilliant physicists like Edward Teller and Richard Feynman are enlivened by his own reminiscences of them. He looks with a skeptical eye at fashionable scientific fads and fantasies, and speculates on the future of climate prediction, genetic engineering, the colonization of space, and the possibility that paranormal phenomena may exist yet not be scientifically verifiable. Dyson also looks beyond particular scientific questions to reflect on broader philosophical issues, such as the limits of reductionism, the morality of strategic bombing and nuclear weapons, the preservation of the environment, and the relationship between science and religion. These essays, by a distinguished physicist who is also a prolific writer, offer informed insights into the history of science and fresh perspectives on contentious current debates about science, ethics, and faith.

Why were Prometheus and Loki envisioned as chained to rocks? What was the Golden Calf? Why are mirrors believed to carry bad luck? How could anyone think that mortals like Perseus, Beowulf, and St. George actually fought dragons, since dragons don't exist? Strange though they sound, however, these "myths" did not begin as fiction. This absorbing book shows that myths originally transmitted real information about real events and observations, preserving the information sometimes for millennia within nonliterate societies. Geologists' interpretations of how a volcanic cataclysm long ago created Oregon's Crater Lake, for example, is echoed point for point in the local myth of its origin. The Klamath tribe saw it happen and passed down the story--for nearly 8,000 years. We, however, have been literate so long that we've forgotten how myths encode reality. Recent studies of how our brains work, applied to a wide range of data from the Pacific Northwest to ancient Egypt to modern stories reported in newspapers, have helped the Barbers deduce the characteristic principles by which such tales both develop and degrade through time. Myth is in fact a quite reasonable way to convey important messages orally over many generations--although reasoning back to the original events is possible only under rather specific conditions. Our oldest written records date to 5,200 years ago, but we have been speaking and mythmaking for perhaps 100,000. This groundbreaking book points the way to restoring some of that lost history and teaching us about human storytelling.

Infinite in All Directions is a popularized science at its best. In Dyson's view, science and religion are two windows through which we can look out at the world around us. The book is a revised version of a series of the Gifford Lectures under the title "In Praise of Diversity" given at Aberdeen, Scotland. They allowed Dyson the license to express everything in the universe, which he divided into two parts in polished prose: focusing on the diversity of the natural world as the first, and the diversity of human reactions as the second half. Chapter 1 is a brief explanation of Dyson's attitudes toward religion and science. Chapter 2 is a one–hour tour of the universe that emphasizes the diversity of viewpoints from which the universe can be encountered as well as the diversity of objects which it contains. Chapter 3 is concerned with the history of science and describes two contrasting styles in science: one welcoming diversity and the other deploring it. He uses the cities of Manchester and Athens as symbols of these two ways of approaching science. Chapter 4, concerned with the origin of life, describes the ideas of six illustrious scientists who have struggled to understand the nature of life from various points of view. Chapter 5 continues the discussion of the nature and evolution of life. The question of why life characteristically tends toward extremes of diversity remains central in all attempts to understand life's place in the universe. Chapter 6 is an exercise in eschatology, trying to define possible futures for life and for the universe, from here to infinity. In this chapter, Dyson crosses the border between science and science fiction and he frames his speculations in a slightly theological context.
