ABSTRACT In 1758 in London, Swedish natural philosopher and mystic theologian Emanuel Swedenborg published De Telluribus in Mundo nostro Solari, a treatise on the plurality of worlds and life on other planets. During the seventeenth and eighteenth centuries, these topics formed a heterogenous literary genre which encompassed theology, astronomy, philosophy and satire. In De Telluribus, Swedenborg made detailed claims of communication with extraterrestrial spirits in the afterlife, through which he sought to spread his theology to new audiences. (...) The paper will explore the role of De Telluribus in Swedenborg's career, explain its content and analyse its polarized reception. It will show that De Telluribus combined for the first time the literary codes of two popular genres during the period, namely those concerning the plurality of worlds and the dialogues of the dead. By doing so, the paper revises current scholarly understanding of Swedenborg by showcasing him as a versatile yet ill-fated recombiner of literary genres. More broadly, the paper will shed light upon previously unnoticed eighteenth-century literary interactions along with a wider overview on the reception of themes such as the plurality of worlds, mysticism and satire in Scandinavia and Germany.

The colonization of a new planet will inevitably bring about new bioethical issues. One is the possibility of pregnancy during the mission. During the journey to the target planet or moon, and for the first couple of years before a colony has been established and the colony has been accommodated for children, a pregnancy would jeopardize the safety of the crew and the wellbeing of the child. The principal concern with a pregnancy during an interplanetary mission is that it could (...) put the entire crew in danger. Resources such as air, food, and medical supplies will be limited and calculated to keep the crew members alive. We explore the bioethical concerns of near-future space travel. (shrink)

what is the ontology of planets?Our access point to this question is the ontology of planet Earth. Although the presence of life marks planet Earth as special among other planets, Earth shares a basic commonality with them – namely, its material existence. We take this commonality as a point of departure for our reflections on the ontology of both planet Earth and other planets. In this chapter, we ask for the ontology of this materiality (...) of planets. We consult the ontology of planet Earth as I developed it in an earlier contribution (Blok, 2019), explore the ontology of planets as absolute boundary of the natural habitats on Earth, and reflect on the opportunities and limitations such ontology provides for future human colonies on other planets.

Informed and guided by ecosystemic thinking, the author addresses the question: What do we need to learn for the sake of dwelling and flourishing with our ‘natural others’ (human beings and all else that exists in our planet) in our era of technological dominance and perverse economic growth which, like a runaway train, continues to accelerate at the expense of natural, social and human capital? Through the storied experiences of Jean Jacques Rousseau, Karl Marx, and Max Weber, the fundamental character (...) of dwelling is interpreted as being-at-home in our world by safeguarding, caring and being a gracious guest in our mutual relationship with natural others. As earthly dwellers the author makes a case for the need to _ever learn_ to be _Guardians_ and _Gracious Guests_ of our natural others by bringing heart and soul into our relationships, including business relationships. This reflective article concludes with three practical exercises for being a Guardian and a Gracious Guest that can be used in organizations and in classrooms. Practical, not in terms of “how-to” but rather practice as a choice and decision between possibilities. (shrink)

Is the Search for Extra Terrestrial Intelligence a genuine scientific research programme? David Lamb evaluates claims and counter-claims, and examines recent attempts to establish contact with other intelligent life forms. He considers the benefits and drawbacks of this communication, how we should communicate and whether we actually can. He also assesses competing theories on the origin of life on Earth, discoveries of former solar planets, proposals for space colonies and the consequent technical and ethical issues.

"We face three epoch-defining environmental problems: climate, extinction and pestilence. Our climate is changing in ways that will have serious consequences for humans, and may even profoundly affect the ability of the planet to support life. All around us, other species are disappearing at a rate between several hundred and several thousand times the normal background rate of extinction. The SARS-CoV-2 virus, which has wreaked social and economic havoc, is merely the latest model off a blossoming production line (...) of newly emerging infectious diseases, many of which have the potential to be far worse. At the heart of these problems lies an ancient habit: eating animals. This habit is the most significant driver of species extinction and of newly emerging infectious diseases, and one of the most important drivers of climate change. This is a habit we can no longer afford to indulge. Breaking it will substantially reduce climate emissions. It will stem our insatiable hunger for land that is at the heart of both the problems of extinction and pestilence. Most importantly, breaking this habit will make available vast areas of land suitable for afforestation: the return of forests to where they once grew. Afforestation will significantly mitigate all three problems. But only if we stop eating animals will we have enough land for this strategy to work"--. (shrink)

Geocentric Greek astronomers called seven heavenly bodies visible to the naked eye (sun, moon, Mercury, Venus, Mars, Jupiter, and Saturn) πλανητες—wanderers—because unlike all the other αστρα, their relative positions were constantly changing. While the Romans changed the Greek names of the individual planets to those still in use, they retained the generic name, which now occurs in many European languages. In acentric modern astronomy a planet is a satellite of a star. In addition to the five actual (...) class='Hi'>planets known to the Greeks, Earth, Uranus, and Neptune also orbit the sun, a smallish star about half the distance from the centre of the Milky Way to its outer reaches. Earth is the only planet on which life is known for certain to exist. The search is on for concrete evidence of existing or formerly existing life on Mars (Dunbar B. et al. Perseverance Mars rover. NASA. https://www.nasa.gov/perseverance. Retrieved 06/16/2021, 2021). Technology for detecting the chemical signature of life in the atmospheres of some planets of other stars may become available in the near future (Fujii Y. et al. Astrobiology 18 (6): 739–778, 2018)—proving a point made by (Lovelock J. Gaia: A new look at life on earth. Oxford University Press, New York, 1979) that life is a whole-planet phenomenon. That is, the Earth does not just harbour or support life; it has a life of its own. The Earth is a living planet in relationship to which individual organisms are as ephemeral cells (Vernadsky VI. Am Sci 33:1–12, 1945). (shrink)

The possibility of seeding other planets with life poses a tricky dilemma. On the one hand, directed panspermia might be extremely good, while, on the other, it might be extremely bad depending on what factors are taken into consideration. Therefore, we need to understand better what is ethically at stake with planetary seeding. I map out possible conditions under which humanity should spread life to other solar systems. I identify two key variables that affect (...) the desirability of propagating life throughout the galaxy. The first is axiological and depends on which value theory in environmental ethics is correct. The second is empirical and depends on whether life is common or not in our region of the universe. I also consider two ethical objections to an interplanetary life-seeding mission: the risk of interfering with indigenous life and the risk of increasing suffering in our galaxy. (shrink)

Experts consider the nature and distribution of life in the universe—from the origin of life on earth to the search for intelligent life on other planets.

This book is aimed at those who wish to understand more about the molecular basis of life and how life on earth may change in coming centuries. Readers of this book will gain knowledge of how life began on Earth, the natural processes that have led to the great diversity of biological organisms that exist today, recent research into the possibility of life on other planets, and how the future of life on earth (...) faces unprecedented pressures from human-made activities. Readers will obtain a perspective on the potential risks of chemical or nuclear warfare, and the ever-increasing risks from human activities that are causing pollution and climate change with global heating. Readers will also learn about ongoing research efforts to generate “designer lifeforms” through synthetic biology and applications of artificial intelligence. The book makes an integrated, up-to-date, overview of topics often considered as separate fields. It should be valuable to students, teachers, and people who are concerned about the future of life.

Abstract:The Wilderness Act characterizes wilderness as "an area where the earth and its community of life are untrammeled by man…" How crucial to the idea of wilderness is its location on our home planet? If an extraterrestrial community of life were discovered, it would certainly be untrammeled by man. Does it make sense to extend the idea of wilderness to encompass other planets and their potential ecosystems? Many values are associated with wilderness, supporting arguments for the (...) need to preserve or protect it. Some arguments seem readily applicable to extraterrestrial habitats, while others may be specific to Earth. I offer an overview of values attributed to wilderness, and consider the extent to which these values may or may not apply beyond the Earth. Following Rolston's claim that nature is not only of value, but a source of values, extraterrestrial wildernesses can be esteemed as instances of a cosmic evolutionary process. (shrink)

Some authors argue that we have a moral obligation to leave Mars the way it is, even if it does not harbour any life. This claim is usually based on an assumption that Mars has intrinsic value. The problem with this concept is that different authors use it differently. In this chapter, I investigate different ways in which an uninhabited Mars is said to have intrinsic value. First, I investigate whether the planet can have moral standing. I find that (...) this is not a plausible assumption. I then investigate different combinations of objective value and end value. I find that there is no way we can know whether an uninhabited Mars has objective end value and even if it does, this does not seem to imply any moral obligations on us. I then investigate whether an uninhabited Mars can have subjective end value. I conclude that this is very plausible. I also investigate whether an uninhabited Mars can have objective instrumental value in relation to some other, non-Mars related end value. I find also this very plausible. It is also highly plausible, however, that spreading life to a presently uninhabited Mars can also have subjective end value, as well as objective instrumental value. I mention shortly two ways of prioritising between these values: The utilitarian method of counting the number of sentient beings who entertain each value and determining the strength of the values to them. Finding a compromise that allows colonisation on parts of the planet while leaving other parts untouched. These methods should be seen as examples, not as an exhaustive list. Also, I do not take a definitive stand in favour of any of the two approaches, though it seems at least prima facie that the second approach may have a better chance of actually leading to a constructive result.

The following story is about the Venerable Mahā-maudgalyāyana,[2] an enlightened disciple of the historical Buddha Śākyamuni. Mahā-maudgalyāyana travels to a distant solar system, to a planet which is inhabited by giant people, and on which there is also a Buddha with disciples practicing under his guidance. The story, which brings to mind Swift’s Gulliver in the land of the giants, is remarkable in many respects. The Buddha and Mahā- maudgalyāyana both probably lived during the fifth and sixth centuries BCE. In (...) the European West, until the time of Galileo (1564-1642), most educated people thought the whole cosmos rotated around the earth and consisted of the sun and seven planets. They did not realize that the stars were other suns. This story here related shows that 2,500 years ago, Buddhists were aware of a vast cosmos filled with suns and planets and sentient life. Contemporary, scientifically oriented people often have a tendency to dismiss non-Western cosmologies as limited, primitive, and distorted myths, in the negative sense of that word. In this story we are presented with a cosmology that seems much closer than the Western pre-Galilean view to the contemporary scientific view of the physical universe. Of course the assertions about the spiritual powers of the Buddha and Mahā-maudgalyāyana and the size of the people on the distant planet do not merge so easily with contemporary scientific, materialist mindsets.

All living human beings have the moral right not to be denied reasonable help in life threatening situations. Disasters take on many forms, but their consequences for individuals may be prolonged and stretch into the next generation.

To do this the commitment to life and its value must be reinforced. A number of suggestions (...) are made, particularly in relation to the role of nurses. Toutes les personnes ont le droit moral de recevoir l'aide raisonable dans des situations menaceant à la vie. Des désastres se présentent sous multiples formes, mais leur conséquences peuvent être prolongées pour des individus jusqu'à la prochaine génération. Nous avons une obligation morale de créér une meilleure vie pour tous les peuples en parlant en faveur de la prévention de désastres et leur conséquences.

Ever since Copernicus, scientists have continually adjusted their view of human nature, moving it further and further from its ancient position at the center of Creation. But in recent years, a startling new concept has evolved that places it more firmly than ever in a special position. Known as the Anthropic Cosmological Principle, this collection of ideas holds that the existence of intelligent observers determines the fundamental structure of the Universe. In its most radical version, the Anthropic Principle asserts that (...) "intelligent information-processing must come into existence in the Universe, and once it comes into existence, it will never die out." This wide-ranging and detailed book explores the many ramifications of the Anthropic Cosmological Principle, covering the whole spectrum of human inquiry from Aristotle to Z bosons. Bringing a unique combination of skills and knowledge to the subject, John D. Barrow and Frank J. Tipler--two of the world's leading cosmologists--cover the definition and nature of life, the search for extraterrestrial intelligence, and the interpretation of the quantum theory in relation to the existence of observers. The book will be of vital interest to philosophers, theologians, mathematicians, scientists, and historians, as well as to anyone concerned with the connection between the vastness of the universe of stars and galaxies and the existence of life within it on a small planet out in the suburbs of the Milky Way.

This paper presents results from a survey of 344 individuals who engage in climate change mitigation action, contributing to debates about whether it is necessary to promote ‘nature experiences’ and biospheric values to encourage pro-environmental behaviour. We investigate three factors – values, motivations and formative experiences – that underlie such behaviour, but that usually have been considered in isolation from each other. In contrast to previous studies of environmentalists’ significant life experiences, outdoor/nature experiences were not frequently mentioned as (...) being influential. Altruistic concerns about climate change impacts on future human generations and on poorer or more vulnerable people were considered more motivating than other reasons for action. There was no significant difference in how respondents rated altruistic and biospheric values. Variations in responses from those involved in ‘biospherically-oriented’ organisations (such as traditional environmental or conservation organisations) versus those involved in climate change groups suggest that there are different routes into climate change mitigation action, and our results show that it is not essential to cultivate biospheric values or the love of nature to encourage such action.

This volume collects thirteen of David Schmidtz's essays on the question of what it takes to live a good life, given that we live in a social and natural world. Part One defends a non-maximizing conception of rational choice, explains how even ultimate goals can be rationally chosen, defends the rationality of concern and regard for others (even to the point of being willing to die for a cause), and explains why decision theory is necessarily incomplete as a tool (...) for addressing such issues. Part Two uses the tools of analytic philosophy to explain what we can do to be deserving, what is wrong with the idea that we ought to do as much good as we can, why mutual aid is good, but why the welfare state does not work as a way of institutionalizing mutual aid, and why transferring wealth from those who need it less to those who need it more can be a bad idea even from a utilitarian perspective. Most ambitiously, Part Two offers an overarching, pluralistic moral theory that defines the nature and limits of our obligations to each other and to our individual selves. Part Three discusses the history and economic logic of alternative property institutions, both private and communal, and explains why economic logic is an indispensable tool in the field of environmental conflict resolution. In the final essay, Schmidtz brings the volume full circle by considering the nature and limits of our obligations to nonhuman species, and how the status of nonhuman species ought to enter into our deliberations about what sort of life is worth living.

The Gaia hypothesis emerged from two interpenetrating traditions, the mechanist and the organicist, with the former tending to reductionism and the latter to holism. While mechanist James Lovelock is the acknowledged father, he collaborated with the organicist Lynn Margulis in the early 1970s when the first papers appeared in the scientific literature. Both continued to be active in Gaia-related conferences until Margulis’s premature death in late 2011. In a very readable exposition, Michael Ruse succeeds brilliantly in tracing the philosophical roots (...) of this concept continuing in the histories of modern geology and biology to its formulation in the late twentieth century.This is Lovelock and Margulis’s definition of the Gaia hypothesis quoted in this book: “We conclude from the fact that the temperature and certain other environmental conditions on the earth have not altered very much from what is an optimum for life on surface, that life must actively maintain these conditions”.

Eternalists say that non-present entities (for instance dinosaurs) exist; presentists say that they do not. But some sceptics deny that this debate is genuine, claiming that presentists simply represent eternalists' quantifiers over non-present entities in different notation. This scepticism may be refuted on purely logical grounds: one of the leading candidate ‘presentist quantifiers’ over non-present things has the inferential role of a quantifier. The dispute over whether non-present objects exist is as genuine and non-verbal as the dispute over whether there (...) is life on other planets. (shrink)

The attempt to define life has gained new momentum in the wake of novel fields such as synthetic biology, astrobiology, and artificial life. In a series of articles, Cleland, Chyba, and Machery claim that definitions of life seek to provide necessary and sufficient conditions for applying the concept of life—something that such definitions cannot, and should not do. We argue that this criticism is largely unwarranted. Cleland, Chyba, and Machery approach definitions of life as classifying (...) devices, thereby neglecting their other epistemic roles. We identify within the discussions of the nature and origin of life three other types of definitions: theoretical, transdisciplinary, and diagnostic definitions. The primary aim of these definitions is not to distinguish life from nonlife, although they can also be used for classificatory purposes. We focus on the definitions of life within the budding field of astrobiology, paying particular attention to transdisciplinary definitions, and diagnostic definitions in the search for biosignatures from other planets.

This book offers a penetrating analysis of issues raised by the perennial question, 'Are We Special?' It brings together scholars from a variety of disciplines, from astronomy and palaeontology to philosophy and theology, to explore this question. Contributors cover a wide variety of issues, including what makes humans distinct from other animals, the possibilities of artificial life and artificial intelligence, the likelihood of life on other planets, and the role of religious behavior. A variety of (...) religious and scientific perspectives are brought to bear on these matters. As a whole, the book addresses whether the issue of human uniqueness is one to which sciences and religions necessarily offer differing responses. (shrink)

A thought-provoking and timely call to apply Judaism's powerful teachings to help shift our imperiled planet onto a sustainable path. While appreciating the radical, transformative nature of Judaism, Richard Schwartz argues that it has been "stolen" by Jews who are in denial about climate change and other environmental threats and support politicians and policies that may be inconsistent with basic Jewish values. Tackling such diverse issues as climate change, world hunger, vegetarianism, poverty, terrorism, destruction of the environment, peace prospects (...) in Israel, and American foreign policy, he offers practical suggestions for getting Judaism back on track as a faith based on justice, peace, and compassion. He urges the reader to reconsider current issues in line with Judaism's highest values in an effort to meet the pressing challenges of today's world. (shrink)

Astrobiologists are aware that extraterrestrial life might differ from known life, and considerable thought has been given to possible signatures associated with weird forms of life on other planets. So far, however, very little attention has been paid to the possibility that our own planet might also host communities of weird life. If life arises readily in Earth-like conditions, as many astrobiologists contend, then it may well have formed many times on Earth itself, (...) which raises the question whether one or more shadow biospheres have existed in the past or still exist today. In this paper, we discuss possible signatures of weird life and outline some simple strategies for seeking evidence of a shadow biosphere.

In lieu of an abstract, here is a brief excerpt of the content:Buddhist-Christian Studies 23 (2003) 155-157 [Access article in PDF] Religious Feminism and the Future of the Planet: A Buddhist-Christian Conversation. By Rita M.Gross and Rosemary Radford Ruether. New York: Continuum, 2001. 229 pp. Is feminism indigenous to Buddhism and Christianity? Or must feminists reinvent their religious traditions? The probing autobiographical reflections by Rita Gross and Rosemary Ruether expose the tensions of feminist reform. Like many religious feminists, they claim (...) to preserve continuity with tradition despite their innovations. But upon reading Religious Feminism and the Future of the Planet, the similarities between feminist Buddhism and feminist Christianity lead me to wonder whether feminism plays a more formative role than tradition in shaping their visions of the future.The ingenious structure of the book allows the opportunity for maximum dialogue. [End Page 155] Authors write chapters paired on the same topic, and each chapter has a short response attached. This organization mirrors the real-life dialogue between Gross and Ruether that occurred at a workshop in Grailville, Ohio, in 1999. The back-and-forth movement allows for meta-reflection on feminist interpretation, on the self-understandings of scholars who practice the traditions that they study.The first two chapters are autobiographical. There is an especially detailed account of Gross's journey toward Tibetan Buddhism and a shorter chapter on the evolution of Ruether's Catholic identity. The second pair of chapters responds to patriarchal religious origins. Ruether's critique of Christian sexism is theological, dealing with Christology, anthropology, and ecclesiology. In contrast, Gross asserts that the Buddhist "view" or theology is nonsexist and even feminist, thus she considers male leadership as the main obstacle to women. The difficulty of defending such large claims in a short space is compensated by the fact that their conclusions have already been developed in previous publications.Striking parallels emerge when the authors identify what is most liberating in their tradition and most inspiring in the other tradition. In both cases, mindfulness practice in Buddhism and the prophetic voice in Christianity are singled out. The overarching message is that Christians can learn about prayer from Buddhists, and Buddhists can learn about social critique from Christians. Another crucial parallel occurs when the authors choose one key social problem to address religiously—they both focus on environmental ethics. They agree that loving care for the earth is the key to both ecological and human flourishing.One asymmetry, however, concerns sensitivity to departure from tradition. In particular, Gross questions whether by utilizing "prophetic" critique she is applying an extrinsic Hebrew and Christian viewpoint to Tibetan Buddhist reflection. I greatly admire how she faces up to the problem of discontinuity between feminist critique and Buddhist institutions rather than insist that the tradition is inchoately feminist. Ruether, on the other hand, does not take the discontinuity between traditional and feminist Christian viewpoints as seriously, although she undoubtedly reshapes Christianity, particularly theological doctrines, into new forms.From a Christian perspective, I notice striking omissions in Ruether's presentation concerning the subject of prayer and the theme of suffering. When Ruether experimented with lay monastic practice early on in her career, she became impatient with silence and intensive prayer as isolating and unproductive. In her autobiographical chapter, she speaks of turning away from prayer toward social engagement. Yet she also mentions admiration for certain contemporary monks and nuns who are on the vanguard of creative worship and ethical engagement. Although she admires Buddhist mindfulness, she does not take seriously analogous Christian meditative practices and their capacity to sustain social activism. She leaves the impression that prayer and action are separate paths, whereas Christian prayer and resistance may be closely associated.The nature of suffering and its overcoming are topics central to Christianity and Buddhism, as well as to feminist thought. For feminists, reflection on suffering tends [End Page 156] to concentrate on exposing and removing its causes, such as abuse, oppression, or violence. Buddhists also focus on cessation of suffering, but "suffering" is centrally an individual barrier to overcome before social issues can be corrected. In contrast, Christians think about... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Buddhist-Christian Studies 23 (2003) 157-158 [Access article in PDF] Religious Feminism and the Future of the Planet: A Buddhist-Christian Conversation. By Rita M.Gross and Rosemary Radford Ruether. New York: Continuum, 2001. 229 pp. This is a delightful book with many strengths. One strength is the framework of questions that organize the book: "What is Most Problematic about My Tradition?" "What is Most Liberating about My Tradition?" "What is Most (...) Inspiring for Me about the Other Tradition?" Gross and Ruether answer these questions in turn both succinctly and powerfully and respond to each other's answers in illuminating ways. These questions are framed by three other sections: an introduction to the nature of the kind of interfaith dialogue that Ruether and Gross have engaged in for many years and that they reproduce in this book; two autobiographies; and an essay by each on what her tradition offers to the task of attaining ecologically sustainable societies so essential to the future of the planet. All of the writing in response to these topics and questions is admirably clear, deep, and engaging. It leads the reader into the heart of the thinking of both Ruether and Gross.Which of the many strengths of the book is the most important to one as a reader depends on whether or not she or he is coming fresh to the thought and scholarship of Ruether or Gross. In my case, although I have read and taught books and articles by Rosemary Ruether over the years, I am not thoroughly familiar with her theological and ethical thought. I learned a great deal from her short, accessible presentations of Christian history and of her theology in this book.On the other hand, I have been very interested for a long time in how gender is [End Page 157] constructed in Buddhism and how women and men have expressed themselves, taught, and acted in Buddhist cultures. I have read all of Rita Gross's past work with great appreciation. I have assigned her book Buddhism after Patriarchy in dozens of courses on Women and Religion and on Buddhism at my university. I found familiar from Rita's other work the arguments, visions, and imaginative reconstructions in this book in answer to the core questions. It is still the case that many Buddhist lineages and communities, particularly where non-Western teachers are in charge, are slow to open the full range of practices and positions of responsibility to women. Yet Buddhist practice has a great deal to offer women. Rita Gross writes eloquently on these topics, with clarity, accuracy, passion, and balance. You can trust her on these subjects.I thus found Rita's autobiographical piece to be the most illuminating offering of the Buddhist part of the book. She tells of the suffering a girl of her nature had to endure in the environment in which she grew up. The facts of her life make evident the extraordinary courage, determination, and commitment she called forth from herself as she forged her own identity and her own pioneering path. She tells of the many roadblocks she encountered from those in authority in her graduate school when she insisted that studying the religion of women was an important task of the History of Religions. Her story illustrates just how powerful the blindness that we academics nourish unchallenged in ourselves can be. It also shows how badly we can act when students demand that we open our eyes. She recounts the difference she believes Buddhist practice made in her ability to sustain her feminist scholarship in the face of persistent lack of academic support.In Rita's autobiography, as also in Rosemary's, one can see how a particular intellectual and moral direction emerged for each woman out of her response to the particular practices and convictions of her social world. Rita's autobiographical piece is very helpful in understanding this great scholar and her times and what Buddhist practice came to mean in the life of a Western feminist scholar of religion. Rosemary's liberal Roman Catholic upbringing... (shrink)

Is one of the roles of theory in biology answering the question “What is life?” This is true of theory in many other fields of science. So why should not it be the case for biology? Yet efforts to identify unifying concepts and principles of life have been disappointing, leading some (pluralists) to conclude that life is not a natural kind. In this essay I argue that such judgments are premature. Life as we know it (...) on Earth today represents a single example and moreover there is positive evidence that it may be unrepresentative of life considered generally. Furthermore, as I discuss, the prototype for theorizing about life has traditionally been based on multicellular plants and animals. Yet biologists have discovered that the latter represent a rare, exotic, and fairly recent form of Earth life. By far the oldest, toughest, most extensive, and diverse form of life on our planet is unicellular, prokaryotic microbes, and there are reasons to suppose that this is almost certainly true elsewhere in the universe as well. If there are explanatorily and predictively powerful, biologically distinctive principles for life that can be gleaned from our insular example of life it is more likely that they will be found among the microbes. I discuss some provocative ways in which unicellular microbes differ from multicellular eukaryotes and argue that some of them just might provide us with key insights into the nature of life.

Ernest Barnes was invited to Aberdeen as Gifford Lecturer (1927-1929) to deliver lectures under the title of 'Scientific Theory and Religion'. The lectures were originally published in 1933 and sought to bring Christian doctrines together with the possibility of life on other planets. The magnitude of the universe, accompanied with some basic observations on biological development within it, makes speculation about the possibility of intelligent life in distant galaxies reasonable. Barnes believed that the Creation was made (...) precisely for the higher forms of' consciousness. The scope of the background to scientific theory and religious ideas of creation presented here is extensive and covers topics including Jewish cosmology as the basis for later Christian thought to early quantum mechanics and evolutionary biology. However, as Barnes himself noted of this scope in his lectures, 'Wide as is their range, they have an inner coherence. I trust that they express the attitude of the modern man of science who, as he hopefully makes theories, is aware of the limitations of his knowledge and also, in part because of his loyalty to truth, bears in mind the reality and the claims of the spiritual world.'.

I discuss the philosophical significance of Kant's great cosmological work of 1755, the Universal Natural History. I discuss how Kant's interest in Newtonian universal forces led him to affirm a peculiar version of the physical influx theory. I argue that Kant's speculations about life on other planets are highly significant because they point to a key feature of Kant's theory of physical influx, namely that "the nimble motions of the body" stand as necessary conditions of the possibility (...) of knowledge. This work directs us to an important topic that has received little scholarly interest: the relation between the body and knowledge in Kant's philosophical writings. (shrink)

In the twenty-first century, the debate about life on other worlds is quickly changing from the realm of speculation to the domain of hard science. Within a few years, as a consequence of the rapid discovery by astronomers of planets around other stars, astronomers very likely will have discovered clear evidence of life beyond the Earth. Such a discovery of extraterrestrial life will change everything. Knowing the answer as to whether humanity has company in (...) the universe will trigger one of the greatest intellectual revolutions in history, not the least of which will be a challenge for at least some terrestrial religions. Which religions will handle the discovery of extraterrestrial life with ease and which will struggle to assimilate this new knowledge about our place in the universe? Some religions as currently practiced appear to only be viable on Earth. Other religions could be practiced on distant worlds but nevertheless identify both Earth as a place and humankind as a species of singular spiritual religious importance, while some religions could be practiced equally well anywhere in the universe by any sentient beings. Weintraub guides readers on an invigorating tour of the world's most widely practiced religions. It reveals what, if anything, each religion has to say about the possibility that extraterrestrial life exists and how, or if, a particular religion would work on other planets in distant parts of the universe.

This article on the epistemology of computational models stems from an analysis of the Gaïa hypothesis. It begins with James Kirchner’s criticisms of the central computational model of GH: Daisyworld. Among other things, the model has been criticized for being too abstract, describing fictional entities and trying to answer counterfactual questions. For these reasons the model has been considered not testable and therefore not legitimate in science, and in any case not very interesting since it explores non actual issues. (...) This criticism implicitly assumes that science should only be involved in the making of models that are “actual” and “specific”. I challenge both of these criticisms in this article. First by showing that although the testability—understood as the comparison of model output with empirical data—is an important procedure for explanatory models, there are plenty of models that are not testable. The fact that these are not testable has nothing to do with their being “abstract” or “what-if” but with their being predictive models. Secondly, I argue that “abstract” and “what-if” models aim at epistemic purposes distinct from those pursued by “actual and specific models”. Abstract models are used to propose how-possibly explanation or to pursue theorizing. What-if models are used to attribute causal or explanatory power to a variable of interest. The fact that they aim at different epistemic goals entails that it may not be accurate to consider the choice between different kinds of model as a “strategy“. (shrink)

Life on Earth descends from a common ancestor. However, it is likely that there are other instances of life in the universe. If so, each abiogenesis event will have given rise to an independently originated life clade, of which Earth-life is an example. In this paper, I argue that the set of all IOLCs in the universe forms a Darwinian population subject to natural selection, with more widely dispersed IOLCs being less likely to face extinction. (...) As a result, we should expect that, over time, more planets will become inhabited by fewer, more successful IOLCs. (shrink)

As many before have done, Richards uses several brief reflections on ethics as a springboard to his discussion of values. In the reviewer’s opinion, much of his seemingly endless wandering during the bulk of the book is due to his mistaken notions about ethics. Richards begins by confusing the justification of moral judgments with the genesis of moral language in a child. Then he speaks of the collapse of ethics because of the amorality of nature and the amorality of man. (...) The first can properly be only a figure of speech; while the second is to mistake what men do for what they ought to do. (shrink)

Daniel C. Dennett is a brilliant polemicist, famous for challenging unexamined orthodoxies. Over the last thirty years, he has played a major role in expanding our understanding of consciousness, developmental psychology, and evolutionary theory. And with such groundbreaking, critically acclaimed books as Consciousness Explained and Darwin's Dangerous Idea (a National Book Award and Pulitzer Prize finalist), he has reached a huge general and professional audience. In this new book, Dennett shows that evolution is the key to resolving the ancient problems (...) of moral and political freedom. Like the planet's atmosphere on which life depends, the conditions on which our freedom depends had to evolve, and like the atmosphere, they continue to evolve-and could be extinguished. According to Dennett, biology provides the perspective from which we can distinguish the varieties of freedom that matter. Throughout the history of life on this planet, an interacting web and internal and external conditions have provided the frameworks for the design of agents that are more free than their parts-from the unwitting gropings of the simplest life forms to the more informed activities of animals to the moral dilemmas that confront human beings living in societies. As in his previous books, Dennett weaves a richly detailed narrative enlivened by analogies as entertaining as they are challenging. Here is the story of how we came to be different from all other creatures, how our early ancestors mindlessly created human culture, and then, how culture gave us our minds, our visions, our moral problems-in a nutshell, our freedom.

Melbourne and Mars was first published in Australia in 1889. The author, Joseph Fraser, was born in England and came to Melbourne, via New Zealand, in 1885. "Marvellous Melbourne," as it was then known, was one of the world's richest and fastest-growing cities, its wealth coming from rich gold deposits. As well as having Australia's wealthiest citizens, however, it also had Australia's worst slumsThis 2020 reprint is introduced and edited by Alexandra Roginsky and Zachary Kendall, of Deakin University. Except for (...) correcting a few spelling errors, they retain the original text.Joseph Fraser was a phrenologist as well as an avid orator and writer.1 He never prospered and, when writing this book, was dying from...

An emerging philosophical perspective called “postphenomenology,” which offers reflection upon human relations to technology, has the potential to increase our understanding of the functions performed by imaging technologies in scientific practice. In what follows, I review some relevant insights and expand them for use in the concrete analysis of practices of image interpretation in science. As a guiding example, I explore how these insights bear upon a contemporary debate in space science over images of the fossilized remains of a river (...) delta on the surface of Mars. These considerations include an analysis of the ways that the objects of study are transformed by the mediating imaging technologies, such as the Mars Orbiter Camera. (shrink)

"Interplanetary travel is very tempting and exciting because the sky is filled with unlimited globes of varying qualities. the desire to travel to other planets can be fulfilled by the process of yoga, which serves as a means by which one can transfer oneself to whatever planet one likes - possibly to planets where life is not only eternal and blissful but where there are multiple varieties of enjoyable energies. Anyone who can attain the freedom of (...) the spiritual planets need never return to this miserable land of birth, old age, disease and death." --Back cover. (shrink)

This paper aims to argue for the thesis that it is not a priori morally justified that the first phase of space colonisation is based on sexual reproduction. We ground this position on the argument that, at least in the first colonisation settlements, those born in space may not have a good chance of having a good life. This problem does not depend on the fact that life on another planet would have to deal with issues such as (...) solar radiation or with the decrease or entire absence of the force of gravity. These issues could plausibly be addressed given that the planets or settlements we will feasibly colonise could be completely transformed through geoengineering processes. Likewise, the ability of humans to live in space could be enhanced through genetic modification interventions. Even if, however, the problems concerning survival in space were solved, we think that, at least in the first period of colonisation of space or other planets, giving birth to children in space could be a morally irresponsible choice since we argue, the life we ​​could give them might not be good enough. We contend that this is the case since when we decide to have a baby. We argue that it is not morally right to be content that our children have a minimally sufficient life worth living; before we give birth to children in space, we should make sure we can give them a reasonable chance of having a good life. This principle applies both on Earth - at least where you can choose - and for space travel. (shrink)
