From its ancient Greek roots to Lovelock's groundbreaking 1979 book, the concept of Gaia has evolved to depict Earth as a single, intricate organism sustaining life through the interplay of its organic and inorganic elements. From the Hadean epoch, where life's emergence radically transformed our planet, to the present, Earth stands as our sole model for understanding life's potential on other Earth-like worlds. While the lifeforms that evolve on Earth-like planets would not necessarily be identical to those on Earth, they must satisfy the same constraints. These constraints are the central subject of this book.Exploring Earth's early conditions during the Hadean era, when oceans dominated and oxygen was scarce, the book illuminates the daunting challenges life faced. Yet, life found its foothold, driven by thermodynamic favorability amidst high tides and shorter days, laying the groundwork for its inevitable emergence. Delving into the fundamental principles of matter and quantum mechanics, the book further highlights life's origin as a product of complex molecular interactions overcoming energy constraints. With insights into the statistical approach to life's origins and the fallacies in estimating life's probability on other planets, the book redefines life as a natural process governed by universal laws.As an underlying theme of this book, life's evolution towards complexity is portrayed as a harmonious extension of non-living processes, challenging the limited conventional view of thermodynamics. Readers will come to appreciate that Earth is a testament to life's resilience and the intricate tapestry woven by biochemical forces across the cosmos.
Gaia, in which James Lovelock puts forward his inspirational and controversial idea that the Earth functions as a single organism, with life influencing planetary processes to form a self-regulating system aiding its own survival, is now a classic work that continues to provoke heated scientific debate.
A classic introduction to the story of Earth's origin and evolution—revised and expanded for the twenty-first century Since its first publication more than twenty-five years ago, How to Build a Habitable Planet has established a legendary reputation as an accessible yet scientifically impeccable introduction to the origin and evolution of Earth, from the Big Bang through the rise of human civilization. This classic account of how our habitable planet was assembled from the stuff of stars introduced readers to planetary, Earth, and climate science by way of a fascinating narrative. Now this great book has been made even better. Harvard geochemist Charles Langmuir has worked closely with the original author, Wally Broecker, one of the world's leading Earth scientists, to revise and expand the book for a new generation of readers for whom active planetary stewardship is becoming imperative. Interweaving physics, astronomy, chemistry, geology, and biology, this sweeping account tells Earth’s complete story, from the synthesis of chemical elements in stars, to the formation of the Solar System, to the evolution of a habitable climate on Earth, to the origin of life and humankind. The book also addresses the search for other habitable worlds in the Milky Way and contemplates whether Earth will remain habitable as our influence on global climate grows. It concludes by considering the ways in which humankind can sustain Earth’s habitability and perhaps even participate in further planetary evolution. Like no other book, How to Build a Habitable Planet provides an understanding of Earth in its broadest context, as well as a greater appreciation of its possibly rare ability to sustain life over geologic time.

In this extensively revised and enlarged edition of his best-selling book, David Suzuki reflects on the increasingly radical changes in nature and science — from global warming to the science behind mother/baby interactions — and examines what they mean for humankind’s place in the world. The book begins by presenting the concept of people as creatures of the Earth who depend on its gifts of air, water, soil, and sun energy. The author explains how people are genetically programmed to crave the company of other species, and how people suffer enormously when they fail to live in harmony with them. Suzuki analyzes those deep spiritual needs, rooted in nature, that are a crucial component of a loving world. Drawing on his own experiences and those of others who have put their beliefs into action, The Sacred Balance is a powerful, passionate book with concrete suggestions for creating an ecologically sustainable, satisfying, and fair future by rediscovering and addressing humanity’s basic needs.
This book describes a wide variety of speculations by many authors about the consequences for humanity of coming into contact with extraterrestrial intelligence. The assumptions underlying those speculations are examined, and some conclusions are drawn. The book emphasizes the consequences of contact rather than the search, and takes account of popular views. As necessary background, the book also includes brief summaries of the history of thinking about extraterrestrial intelligence, searches for life and for signals, contrasting paradigms of how contact might take place, and the paradox that those paradigms allegedly create.
• Examines how integrating important alchemical images with Gaian science can offer insights into our interconnectedness with Gaia • Looks at how the four components of the living earth--biosphere, atmosphere, hydrosphere, and lithosphere--mesh with the four elements of alchemical theory and the four functions of consciousness as understood by depth psychology • Offers guided meditations and contemplative exercises to open your receptivity to messages from the biosphere and help you connect more deeply with Gaia During the scientific revolution, science and soul were drastically separated, propelling humanity into four centuries of scientific exploration based solely on empiricism and rationality. But, as scientist and ecologist Stephan Harding, Ph.D., demonstrates in detail, by reintegrating science with profound personal experiences of psyche and soul, we can reclaim our lost sacred wholeness and help heal ourselves and our planet. The book begins with compelling introductions to depth psychology, alchemy, and Gaia theory--the science of seeing the Earth as an intelligent, self-regulating system, a theory pioneered by the author’s mentor James Lovelock. Harding then explores how alchemy, as understood through the depth psychology of C. G. Jung, offers us powerful methods of reuniting rationality and intuition, science and soul. He examines the integration of important alchemical engravings, including those from L’Azoth des Philosophes and the Rosarium Philosophorum, with Gaian science. He shows how the seven key alchemical operations in the Azoth image can help us develop deeply transformative experiences and insights into our interconnectedness with Gaia. He then looks at how the four components of the living Earth--biosphere, atmosphere, hydrosphere, and lithosphere--mesh not only with the four elements of alchemical theory but also with the four functions of consciousness from depth psychology. Woven throughout with the author’s own experiences of Gaia alchemy, the book also offers guided meditations and contemplative exercises to open your receptivity to messages from the biosphere and help you develop your own Gaian alchemical way of life, full of wonder and healing.
In this portrait of Planet Earth-at just about the mid point of its probable lifespan-a biologist discusses the evolution of the network of life and the crucial role played by humans in determining the future of our world.Unlike most books on earth history, which present the story of life on our planet in terms of one chronological period after another, the author discusses Earth''s teeming diversity in terms of pivotal evolutionary developments. Among these he stresses the importance of symbiosis, sex, and altruism as key determinants of the Earth''s biodiversity. Symbiosis-when single cells began working together-sparked the sudden appearance of complex animals. Much later symbiotic relationships led to flowering plants that depended on animals for pollination and seed dispersal. With the advent of sexual selection, there developed an astonishing world of complex behavior and a dizzying array of life forms. In humans, sexual selection exerted a great influence on the development of our large brains. Altruism-when species learned to work together-resulted in even greater variety and complexity. In early humans, altruism gave rise to ever-widening social circles and the spread of culture. The author also discusses the role of photosynthesis in establishing and maintaining life on earth; the evidence for ancient natural catastrophes, which caused widespread extinctions; and the importance of religion and the recent use of scientific reasoning in the development and the future of the human species. This eloquent, panoramic perspective is well designed to foster an appreciation for the scope of life on Earth and to encourage wise stewardship of the natural world on which our survival depends.
This classic work is reissued with a new preface by the author. Written for non-scientists the idea is put forward that life on Earth functions as a single organism.
The only thing we can be absolutely sure of is our own consciousness. But what is consciousness? Is it a property that is unique to humans or do we share it with other lifeforms? Or is the philosophical doctrine of panpsychism correct—are stars and the entire universe conscious in some sense? Early chapters in this book examine the prehistory, mythology, and history of this topic. Arguments are presented from the viewpoints of shamans, philosophers, poets, quantum physicists, and novelists. A simple “toy” model of panpsychism is then presented, in which a universal field of proto- consciousness interacts with molecular bonds via the vacuum fluctuation pressure of the Casimir Effect. It is shown how this model is in congruence with an anomaly in stellar motions called “Parenago’s Discontinuity.” Cool, redder, less massive stars such as the Sun apparently circle the center of the galaxy faster than their hotter, bluer, more massive sisters. This discontinuity occurs at the point in the stellar distribution where molecules begin to appear in stellar spectra. As described in the first edition of this book, observations of main sequence stars out to ~260 light years and giant stars out to >1,000 light years—using the ESA Hipparcos space observatory—support the reality and non-locality of Parenago’s Discontinuity. Local, more conventional explanations for this phenomenon are not supported by observations of other galaxies and the spiral arms of the Milky Way. Since 2014, the new ESA Gaia space observatory has been obtaining kinematics and position data for ~1 billion stars in our galaxy. The first Gaia data release in 2016 has been used in 2018 by a Russian team to demonstrate Parenago’s Discontinuity for a large stellar sample out to ~500 light years from the Sun. These observations support the hypothesis that anomalistic stellar motion is due to stellar volition, as described by philosopher/author Olaf Stapledon in his classic novel Star Maker, as previously discussed by the author in the peer-reviewed Journal of the British Interplanetary Society (JBIS). In light of the new Gaia observations and work by other researchers, it is not impossible that panpsychism is emerging from the realm of philosophy as a new subdivision of observational astronomy. Simple models of universal proto-consciousness may be subject to inductive tests using current and future space observatories. A special feature of this book is the chapter frontispiece art by C Bangs.
Eighteen essays plus four examples from the ninth annual J. Lloyd Eaton Conference on Science Fiction and Fantasy Literature at the University of California, Riverside. The concept of mindscape, Slusser and Rabkin explain, allows critics to focus on a single fundamental problem: "The constant need for a relation between mind and some being external to mind." The essayists are Poul Anderson, Wendy Doniger O'Flaherty, Ronald J. Heckelman, David Brin, Frank McConnell, George E. Slusser, James Romm, Jack G. Voller, Peter Fitting, Michael R. Collings, Pascal J. Thomas, Reinhart Lutz, Joseph D. Miller, Gary Westfahl, Bill Lee, Max P. Belin, William Lomax, and Donald M. Hassler. The book concludes with four authors discussing examples of mindscape. The participants are Jean-Pierre Barricelli, Gregory Benford, Gary Kern, and David N. Samuelson.
