This book, a collection of essays written by the most eminent evolutionary biologist of the twentieth century, explores biology as an autonomous science, offers insights on the history of evolutionary thought, critiques the contributions of philosophy to the science of biology, and comments on several of the major ongoing issues in evolutionary theory. Notably, Mayr explains that Darwin's theory of evolution is actually five separate theories, each with its own history, trajectory and impact. Natural selection is a separate idea from common descent, and from geographic speciation, and so on. A number of the perennial Darwinian controversies may well have been caused by the confounding of the five separate theories into a single composite. Those interested in evolutionary theory, or the philosophy and history of science will find useful ideas in this book, which should appeal to virtually anyone with a broad curiosity about biology.
A New Environmental Ethics by Holmes Rolston III Pdf
This Second Edition of A New Environmental Ethics: The Next Millennium for Life on Earth offers clear, powerful, and often moving thoughts from Holmes Rolston III, one of the first and most respected philosophers to write on the environment and often called the "father of environmental ethics." Rolston surveys the full spectrum of approaches in the field of environmental ethics and offers critical assessments of contemporary academic accounts. He draws on a lifetime of research and experience to suggest an outlook, and even hope, for the future. This forward-looking analysis, focused on the new millennium, will be a necessary complement to any balanced textbook or anthology in environmental ethics. The First Edition guaranteed "to put you in your place." Beyond that, the Second Edition asks whether you want to live a "de-natured life on a de-natured planet." Key Updates in the Second Edition Covers the worsening environmental situation due to actions of the Trump administration, including withdrawal from the Paris Agreement and from the U.N. Framework Convention on Climate Change Includes information on legislation in key U.S. states (e.g., California and New York) aimed to ameliorate the damage done at the federal level Increases coverage of group knowledge, group agreement and disagreement, and group action in collective environmental ethics, as distinguished from individual knowledge and action Examines the deleterious effects of online consumer behavior Explains how a loss of solidarity among a nation’s citizens and even a larger solidary among humanity leads to environmental degradation Offers new analysis of the effects of epistemic bubbles, echo chambers, and fake news on the behavior of voters and consumers Provides an extended critique of the Anthropocene Epoch, and the prospect of geo-engineering Earth to become a synthetic environment.
The Planet-Girded Suns: Our Forebears' Firm Belief in Inhabited Exoplanets by Sylvia Engdahl Pdf
Interest in exoplanets--the worlds of other stars--is not new. From the late 17th century until the end of the 19th, almost all educated people believed that the stars are suns surrounded by inhabited planets--a belief that was expressed not in science fiction, but in serious speculation, both scientific and religious, as well as in poetry. Only during the first half of the 20th century was it thought that life-bearing exoplanets are rare. This is not a science book--rather, it belongs to the category known as History of Ideas. First published by Atheneum in 1974, it tells the story of the rise, fall, and eventual renewal of widespread conviction that we are not alone in the universe. In this 2012 updated edition the chapters dealing with modern speculation have been revised to reflect the progress science has made during the past 40 years, including the actual detection of planets orbiting other stars. However, it is not intended to be more than a brief introduction to today's views; its focus is on little-known facts about those of the past. Why should we care what our forebears believed? Now, the question of ET life is a matter for investigation by science. Yet it's significant that most educated people of past centuries were convinced that other inhabited worlds exist, without any scientific evidence whatsoever. This historical fact reveals that human beings have an instinctive sense of kinship with the wider universe and a desire to see the realms that lie beyond this one small planet--and perhaps, eventually, to go there. Our ancestors conceived of such voyages only in a spiritual sense, as occurring after death. But we who have taken our first small steps into space are aware that our descendants may set foot on the worlds of other suns. Just as in the 17th century people were initially upset by the new knowledge that the stars are suns scattered in space rather than lights fixed to a nearby sphere, the growing awareness that Earth is not safely isolated from whatever lies beyond makes many of our contemporaries uneasy. Thus today's predominant feelings about spaceships are ambivalent. Nevertheless, if an impulse toward belief that we are not alone in the universe is indeed an innate characteristic of human beings, as the past spread of belief in inhabited exoplanets suggests, we can be sure that those who follow us will not turn back from becoming spacefarers.
Portraying themselves as challenging blind religious dogma with evidence-led skepticism, the neo-atheist movement claims that the New Testament contains unreliable tales about a mythical figure who, far from being the resurrected Lord of life, may not even have lived. This comprehensive critique documents the falsehood of these neo-atheist claims, correcting their historical and philosophical mistakes to show how we can get at the truth about the historical Jesus.
Contact with Alien Civilizations by Michael Michaud Pdf
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.
This book is, in a sense, a sequel to David Seargent's first Springer book Weird Astronomy (2010). Whereas Weird Astronomy extended over a broad range of purely astronomical topics, the present work concentrates on phenomena closer to home; the atmospheric and "shallow space" events as opposed to deep space events. The line between astronomy and meteorology is blurred - a fact that is discussed in Weird Weather. It is not primarily a book of "wonders" or of the unexplained, although some of the topics covered remain mysteries. It is primarily directed toward those who are fascinated by climate and weather, and who are open-minded when considering Earth's climate, what drives it, and what are the causes of climate change. The author, David A. J. Seargent, presents the facts with a balanced and scientific approach. Weird Weather: Tales of Astronomical and Atmospheric Anomalies is about strange, unusual, and apparently inexplicable observations of the air and sky. Primarily these are in the Earth's atmosphere, but there are corresponding phenomena in the atmospheres of other planets of the Solar System - lightning on Venus, Jupiter, and Saturn, whirlwinds and dust storms of Mars, and auroras on Jupiter. Topics include anomalous lights, anomalous sounds, spectacular effects of cloud illumination by the Sun or Moon, lightning phenomena, electrophonic sounds of lightning, aurora and meteors, tornado and whirlwind phenomena on Earth and Mars, usual atmospheric effects, mirages, and the possible astronomical influences on cloud and climate.
Africa's Past, Our Future by Kathleen R. Smythe Pdf
“An impressive synthesis of current literature in African history, making it understandable and relevant.” —Jan Bender Shetler, author of Imagining Serengeti: A History of Landscape Memory in Tanzania from Earliest Times to the Present Africa’s Past, Our Future engages the history of the African continent through the perspective of global issues such as political instability, economic development, and climate change. Since the past may offer alternative models for thinking about our collective future, this book promotes an appreciation for African social, economic, and political systems that have endured over the long-term and that offer different ways of thinking about a sustainable future. Introducing readers to the wide variety of sources from which African history is constructed, the book’s ten chapters cover human evolution, the domestication of plants and animals, climate change, social organization, the slave trade and colonization, development, and contemporary economics and politics. “Smythe not only provides an excellent survey of the latest research on Africa’s past, she also presents a concise and clear argument as to why this history is relevant today.” ?African Studies Review “Recommended.” ?Choice “Grapples with the narratives and facts and where they fit in global perspective, but why this is all salient and critically meaningful to our lives today in terms of lessons we can learn and ideas we can borrow. This is a unique approach not yet available on the market.” ?Catherine Cymone Fourshey, Susquehanna University

After a substantial new essay examining the nature of a properly skeptical historical inquiry into Jesus of Nazareth in the context of contemporary worldviews, from pre-modernism to meta-modernism, Behold the Man presents revised essays on an eclectic range of issues: from how the Epistle of James treats Jesus as Divine within decades of the crucifixion, and an evaluation of recent arguments about the dating of the Fourth Gospel, to debunking claims about Jesus and “ancient aliens,” and furthering debate about the resurrection. With a foreword by eminent New Testament scholar Craig L. Blomberg, and extensive recommended resources, Behold the Man: Essays on the Historical Jesus represents a wide-ranging, interdisciplinary engagement with historical Jesus studies.
