“[Ruse’s] treatment is thought-provoking and original, as you would expect from this perceptive, irrepressible philosopher of biology.”

New Scientist

“Fascinating. . . . The book is full of empathetic, insightful, and often very funny portraits of Margulis, Lovelock, and a community of other figures associated with Gaia and its histories. It is also a wonderfully lively and readable narrative.”

Carla Nappi | New Books in Science, Technology, and Society

"Explores the philosophical and historical bases of Gaia’s principle, beginning with Plato and taking readers up to the present with modern ecology and evolutionary biology. . . . There are few people writing today more qualified than Ruse to take on this job. He has the history and philosophical skills to tackle the literature across millennia, and his three-decade immersion in evolution allows him to read critically from complicated sources. Best of all, he still knows how to write in a way that makes philosophy and science fun."

Quarterly Review of Biology

"Anyone interested in the Gaia hypothesis--its history, its philosophical underpinnings and the scientific controversy over it in the mid-twentieth-century--will find this book an exceptionally interesting read."

Paul Thompson | Studies in History and Philosophy of Biological and Biomedical Sciences

"Fascinating. . . . A refreshing reminder of just how much the scientific enterprise is a social phenomenon, both in its inner workings and in how it is affected by the broader social milieu."

Massimo Pigliucci, City University of New York | Ethics and the Environment

"Written with Ruse’s usual flair and attention to the relevant evidence (that he shows is itself rich and varied), this book is scholarly and illuminating, on the one hand, and a thoroughly enjoyable read, on the other."

Lynn Hankinson Nelson, University of Washington | Soundings: An Interdisciplinary Journal

"Original, well researched, timely, and well written. . . . In short, The Gaia Hypothesis is highly recommended reading."

Arthur C. Peterson, University College London | European Society for the Study of Science and Theology

“Entertaining and highly readable. . . . The value of Ruse’s book is in how he captures the wider importance of the debate triggered by the Gaia hypothesis. Like all good philosophers, he makes the reader think about how we think.”

Tim Lenton, University of Exeter | BioScience

“Few philosophers have blended the history and philosophy of science more successfully than Michael Ruse. And no contemporary scholar has played a more active role in establishing and maintaining the boundaries of science. In this riveting examination of the Gaia hypothesis—that is, the claim that Earth is a living planet—Ruse even-handedly applies his expertise to dissecting a controversial case where science, pseudoscience, and religion all came into play.”

Ronald L. Numbers, University of Wisconsin—Madison

“Written with Michael Ruse’s trademark combination of storytelling verve and philosophical insight, this book offers a fascinating history of the appealing but scientifically heretical idea that the earth is in some sense alive. Ruse not only recounts the successes and failures of this intriguing notion, but along the way poses searching questions about the nature of science and its popular reception.”

Peter Harrison, author of The Fall of Man and the Foundations of Science

“Michael Ruse has a habit of tackling big ideas in the history and philosophy of science, and there is hardly any idea bigger than the Gaia hypothesis. Ruse situates James Lovelock and Lynn Margulis’s theory of Earth as a living, self-regulating organism within several contexts, ranging from their personal biographies to the long history of mechanism and organicism in the life sciences. The trek through the past helps make sense of both the immense popularity of Gaia among the lay public and the hostility it faced from professional scientists, as Ruse contends that they are both part of the same process.”

Michael D. Gordin, author of The Pseudoscience Wars
