What are the implications for human society, and for our institutions of higher learning, of the discovery of a sophisticated extraterrestrial intelligence (ETI) operating on and around Earth? This book explores this timely question from a multidisciplinary perspective. It considers scientific, philosophical, theological, and interdisciplinary ways of thinking about the question, and it represents all viewpoints on how likely it is that an ETI is already operating here on Earth. The book’s contributors represent a wide range of academic disciplines in (...) their formal training and later vocations, and, upon reflection on the book’s topic, they articulate a diverse range of insights into how ETI will impact humankind. It is safe to say that any contact or communication with ETI will not be merely a game changer for human society, but it also will be a paradigm changer. It makes sense for human beings to prepare themselves now for this important transition. (shrink)

The physicist Richard Gott defends the Copernican principle, which claims that when we have no information about our position along a given dimension among a group of observers, we should consider ourselves to be randomly located among those observers in respect to that dimension. First, I apply Copernican reasoning to the distribution of evil in the universe. I then contend that evidence for intelligent extraterrestrial life strengthens four important versions of the argument from evil. I remain neutral regarding whether this (...) result is a reductio of these arguments from evil or the statement of a genuine evidential relationship. (shrink)

Copernican reasoning involves considering ourselves, in the absence of other information, to be randomly selected members of a reference class. Consider the reference class intelligent observers. If there are extraterrestrial intelligences (ETIs), taking ourselves to be randomly selected intelligent observers leads to the conclusion that it is likely the Earth has a larger population size than the typical planet inhabited by intelligent life, for the same reason that a randomly selected human is likely to come from a more populous country. (...) The astrophysicist Fergus Simpson contends that this reasoning supports the claims that the typical planet inhabited by ETIs is smaller than Earth (radius about 5,000km; cf. Earth's radius = 6,371km) and that the typical ETI is significantly larger than us about 314kg, the size of an adult male grizzly bear). Simpson's applications of Copernican reasoning are novel and exciting. They should be of interest to philosophers concerned with Richard Gott's delta t argument, the N=1 problem in astrobiology, limited principles of indifference, and probabilistic epistemology in general. While we agree with Simpson about the qualitative direction of his conclusions, we take issue with his presentation of precise quantitative results because his methods (1) display bias, (2) ignore other variables contributing to population size, (3) commit an equivocation, and (4) conceal their dependence on arbitrary assumptions.

The recent explosion in the discovery of exoplanets and our incipient ability to detect atmospheric biomarkers recommend reflection on the conceptual implications of discovering – or not discovering – extrasolar life. I contend that evidence for intelligent extraterrestrial life is evidence against the existence of God, because if there are intelligent extraterrestrials, there are likely to be evils in the universe even greater than those found on Earth. My reasoning is based on Richard Gott's Copernican Principle, which holds that (...) in the absence of information to the contrary, we should take ourselves to be typical observers. (shrink)

Developments that suggest the universe is full of life make the Fermi paradox increasingly pressing, but our search for an extraterrestrial technological civilization (“ETC”) is handicapped by our ignorance of its probable nature and behavior. This paper offers a way around this problem by drawing on information theoretical concepts, including game theory and Bayesian probability. It argues that, whatever its ultimate goals, an ETC would have the same instrumental goals as other intelligent agents. Generically, these are self-preservation and the acquisition (...) of resources. For an advanced ETC, these generic goals imply the objectives of removing existential threats and acquiring strategic and non-strategic information. Since the most problematic existential threats for any ETC would be from other civilizations and planets hosting such civilizations would also be copious sources of information, these objectives would lead it to gather information from these locations and to protect itself against them. This dual-goals hypothesis resolves the Fermi paradox, redirects the search for extraterrestrial intelligence and makes testable predictions regarding ETC’s behavior on Earth if it is here. (shrink)

In this article, we develop the intersection of Shīʿī Islamic philosophy and extraterrestrial life. We explain the view of Ḥukamā (Islamic Philosophers) and what implications it holds for asserting a plurality of worlds and life forms. In addition to this, we bring Shīʿī hadīth sources which also suggest the existence of other life forms outside the earth. Combining the philosophical and textual evidence, we argue that the Shīʿī school not only suggests the existence of extraterrestrial life but also provides a (...) potential framework for possible human-extraterrestrial interactions.

New theological understanding can emerge with the advancement of scientific knowledge and the use of new concepts, or older concepts in new ways. Here, the authors present a proposal to extend the concept of “rescue and recovery” found in the United Nations Law of the High Seas, off‐world and within a broader purview of other intelligent and self‐aware species that humans may someday encounter. The notion of a morality that extends to off‐world species is not new, but in this analysis, (...) rescue and recovery become an imperative when any intelligent and self‐aware species is in harm's way. Rescue and recovery encompass a necessary action component except perhaps in those cases where rescuers are in danger. The authors explore three biblical examples of rescue and recovery to derive a fundamental meaning of the concept. (shrink)

Would the existence of extraterrestrial intelligent life conflict in any way with Christian belief? We identify six areas of potential conflict. If there be no conflict in any of these areas—and we argue ultimately there is not—we are confident in declaring that there is no conflict, period. This conclusion underwrites the integrity of theological explorations into the existence of ETI, which has become a topic of increasing interest among theologians in recent years.

This article explores the essence of the human (insān) as it is understood in Twelver Shīʿī philosophy and mysticism. It presents a Shīʿī philosophical elucidation regarding the possible existence of extraterrestrial intelligent lifeforms and what their relationship with “humanhood” might be. This line of reasoning is presented with a general sketch of how, in Shīʿī Islamic thought, a “human being” is characterized by specific traits and the relationship of human beings with the archetype of the Perfect Human (al‐Insān al‐Kāmil). Following (...) this is a review of Shīʿī Imāmī traditions regarding extraterrestrial intelligent life and the plurality of worlds. This sequence ultimately allows for a unique analysis of humanhood according to the Shīʿī philosophical viewpoint and helps determine if the term “human” can be used for other intelligent beings with similar ontological features and intelligence levels.

The project “A Plurality of Lives” was funded and hosted by the Pufendorf Institute for Advanced Studies at Lund University, Sweden. The aim of the project was to better understand how a second origin of life, either in the form of a discovery of extraterrestrial life, life developed in a laboratory, or machines equipped with abilities previously only ascribed to living beings, will change how we understand and relate to life. Because of the inherently interdisciplinary nature of the project aim, (...) the project took an interdisciplinary approach with a research group made up of 12 senior researchers representing 12 different disciplines. The project resulted in a joint volume, an international symposium, several new projects, and a network of researchers in the field, all continuing to communicate about and advance the aim of the project.

In this article, a classification of the global catastrophic risks connected with the possible existence (or non-existence) of extraterrestrial intelligence is presented. If there are no extra-terrestrial intelligences (ETIs) in our light cone, it either means that the Great Filter is behind us, and thus some kind of periodic sterilizing natural catastrophe, like a gamma-ray burst, should be given a higher probability estimate, or that the Great Filter is ahead of us, and thus a future global catastrophe is high probability. (...) If ETIs exist in our light cone, it is most likely they exist in the form of ET artificial general intelligence (ETAI). ETAI may be traveling at near-light speed as an explosive wave of intelligence in the form of some nano-mechanisms which could reach us at any moment; may send us potentially dangerous messages with AI-virus payloads; or be near or on Earth in some dormant form. This dormant form could be nanobots, which could act as berserkers, and be triggered when humans unwittingly cross some threshold. If ETIs are nearby and less advanced, they could find our messaging extra-terrestrial intelligence (METI) messages and send their “fleet” to or direct weapons toward Earth. Even extinct ETIs could have left dangerous remnants in the form of AI systems that our civilization may encounter. If our existence is a simulation, this could be run by ETIs. Even a false belief in the existence of ETIs could potentially fuel millennial sects. If humanity is the first intelligence to emerge, it may kill or prevent the existence of all future potential ETI, a different type of catastrophe. Several options to prevent catastrophic risks are connected with ETI: sending requests for help, using random strategies to escape the Fermi paradox, Great Filter prediction, or the hope that ETIs will find the remains of our extinct civilization and resurrect it.

All SETI (Search for Extraterrestrial Intelligence) programmes that were conceived and put into practice since the 1960s have been based on anthropocentric ideas concerning the definition of intelligence on a cosmic-wide scale. Brain-based neuronal intelligence, augmented by AI, are currently thought of as being the only form of intelligence that can engage in SETI-type interactions, and this assumption is likely to be connected with the dilemma of the famous Fermi paradox. We argue that high levels of intelligence and cognition inherent (...) in ensembles of bacteria are much more likely to be the dominant form of cosmic intelligence, and the transfer of such intelligence is enabled by the processes of panspermia. We outline the main principles of bacterial intelligence, and how this intelligence may be used by the planetary-scale bacterial system, or the bacteriosphere, through processes of biological tropism, to connect to any extra-terrestrial microbial forms, independently of human interference.

Abstract: After 2017 NY Times publication, the stigma of the scientific discussion of the problem of so-called UAP (Unidentified Aerial Phenomena) was lifted. Now the question arises: how UAP will affect the future of humanity, and especially, the probability of the global catastrophic risks? To answer this question, we assume that the Nimitz case in 2004 was real and we will suggest a classification of the possible explanations of the phenomena. The first level consists of mundane explanations: hardware glitches, malfunction, (...) hoaxes and lies. The second level involves explanations which are not changing completely our model of the world, but only updating it: new military tech, large psyop operation or new physical effect like ball lightning. The third level of explanations requires a complete overhaul of our world model and includes a large set of fantastic hypothesis: alien starships, interdimensional beings, glitches in the matrix, projections from the collective unconsciousness, Boltzmann brain’s experiences etc. The higher is the level of the hypothesis, the less probable it is, but the bigger is its consequences for possible global catastrophic risks. Thus, “integrating” over the field of all possible explanations, we find that UAP increases catastrophic risks. Technological progress increases our chances of direct confrontation with the phenomena. If the phenomenon has intelligence, the change of its behavior could be unexpected after we pass some unknown threshold. But we could lower the risks if we assume some reasonable policy of escaping confrontations. (shrink)

As space travel and intentions to colonise other planets are becoming the norm in public debate and scholarship, we must also confront the technical and survival challenges that emerge from these hostile environments. This paper aims to evaluate the various arguments proposed to meet the challenges of human space travel and extraterrestrial planetary colonisation. In particular, two primary solutions have been present in the literature as the most straightforward solutions to the rigours of extraterrestrial survival and flourishing: (1) geoengineering, where (...) the environment is modified to become hospitable to its inhabitants, and (2) human (bio)enhancement where the genetic heritage of humans is modified to make them more resilient to the difficulties they may encounter as well as to permit them to thrive in non-terrestrial environments. Both positions have strong arguments supporting them but also severe philosophical and practical drawbacks when exposed to different circumstances. This paper aims to show that a principled stance where one position is accepted wholesale necessarily comes at the opportunity cost of the other where the other might be better suited, practically and morally. This paper concludes that case-by-case evaluations of the solutions to space travel and extraterrestrial colonisation are necessary to ensure moral congruency and the survival and flourishing of astronauts now and into the future.

On the surface Kant himself seems quite clear about who is deserving of respect: The morally relevant others are all “rational, free beings” or all “human beings.” It is clear, however, that Kant does not want to identify “human beings” in this sense with members of a particular biological species, for he is explicitly open to the idea that there might be non-biologically human rational beings. Thus, for example he is explicitly open to the possibility of extraterrestrial rational beings, who (...) would not be members of the same biological species as us, but who would, presumably be worthy of respect. And it would seem possible that there are members of our biological species who are not “human” in the morally relevant sense. Given these facts, a Kantian needs to give some account of how we are to recognize who or what counts as “human” in the morally relevant sense. I argue that to be “human” in the morally relevant sense is to have the capacity for morality, and that this involves: (a) the capacity to recognize others as ends rather than merely as means and (b) the capacity to enter into relations of ethical community with us. I defend a position I name moral reliabilism. According to this position: (a) We have a quasi-perceptual capacity to directly ascribe moral status to various bits of the world around us. I will argue that this capacity is best thought of in Gibsonian terms as a capacity to pick up on certain types of social affordances; morally relevant others have the capacity to engage in ethical interaction with us, and recognizing the humanity of others involves picking up on this capacity. Those beings who are “human” in the morally relevant sense, then, afford interaction based on mutual respect. (b) We should assume as a postulate of practical reason that this capacity is reliable (although fallible). (shrink)

In searching for life in extraterrestrial space, it is essential to act based on an unequivocal definition of life. In the twentieth century, life was defined as cells that self-replicate, metabolize, and are open for mutations, without which genetic information would remain unchangeable, and evolution would be impossible. Current definitions of life derive from statistical mechanics, physics, and chemistry of the twentieth century in which life is considered to function machine like, ignoring a central role of communication. Recent observations show (...) that context-dependent meaningful communication and network formation (and control) are central to all life forms. Evolutionary relevant new nucleotide sequences now appear to have originated from social agents such as viruses, their parasitic relatives, and related RNA networks, not from errors. By applying the known features of natural languages and communication, a new twenty-first century definition of life can be reached in which communicative interactions are central to all processes of life. A new definition of life must integrate the current empirical knowledge about interactions between cells, viruses, and RNA networks to provide a better explanatory power than the twentieth century narrative.

Leading cosmological theories engender a controversial puzzle which has prompted philosophers to propose competing epistemological solutions and physicists to propose methodological changes to cosmology. The puzzle arises from the prediction that every brain on Earth will eventually be vastly outnumbered by physical duplicates formed by random collisions of particles in outer space. Supposing that this prediction is correct, shouldn't you believe that your brain is probably one of these vastly more typical extraterrestrial brains, since you cannot infer your brain's origin (...) from your experiential state? But supposing that your brain is one of these extraterrestrial brains, why be confident in the cosmological theories, since you never actually received testimony supporting these theories? Proposals in the literature either deny the rationality of believing theories that make the prediction or deny the typicality of your brain among its duplicates. This paper argues that these proposals are not entirely satisfactory. Instead, one should be confident in theories making the prediction on the supposition that your brain is one of the extraterrestrial brains. The upshots include that it may be rational to believe that your brain is probably an extraterrestrial brain and that cosmologists should not alter their methodology in response to the puzzle.

Research groups around the world are currently busy trying to invent new life in the laboratory, looking for extraterrestrial life, or making machines increasingly more life-like. In the case of astrobiology, any newly discovered life would likely be very old, but when discovered it would be new to us. In the case of synthetic organic life or life-like machines, humans will have invented life that did not exist before. Together, these endeavors amount to what we call the emerging plurality of (...) lives because we see a future where we are surrounded by, and interact with, life of many different origins, as well as entities that we have not traditionally seen as being alive. In the future these entities will likely possess properties that we so far have only associated with living beings, thereby transcending and perhaps blurring the borders between life and non-life.

A high standard of planetary protection is important for astrobiology, though the risk for contamination can never be zero. It is therefore important to find a balance. If extraterrestrial life has a moral standing in its own right, it will also affect what we have to do to protect it. The questions of how far we need to go to protect extraterrestrial life will be even more acute and complicated when the time comes to use habitable worlds for commercial purposes. (...) There will also be conflicts between those who want to set a world aside for more research and those who want to give the green light for development. I believe it is important to be proactive in relation to these issues. The aim of my project is therefore to identify, elucidate, and if possible, suggest solutions to potential conflicts between astrobiology, planetary protection, and commercial use of space. (shrink)

This paper aims to justify the concept of natural intelligence in the biosemiotic context. I will argue that the process of life is (i) a cognitive/semiotic process and (ii) that organisms, from bacteria to animals, are cognitive or semiotic agents. To justify these arguments, the neural-type intelligence represented by the form of reasoning known as anthropic reasoning will be compared and contrasted with types of intelligence explicated by four disciplines of biology – relational biology, evolutionary epistemology, biosemiotics and the systems (...) view of life – not biased towards neural intelligence. The comparison will be achieved by asking questions related to the process of observation and the notion of true observers. To answer the questions I will rely on a range of established concepts including SETI (search for extraterrestrial intelligence), Fermi’s paradox, bacterial cognition, versions of the panspermia theory, as well as some newly introduced concepts including biocivilisations, cognitive/semiotic universes, and the cognitive/semiotic multiverse. The key point emerging from the answers is that the process of cognition/semiosis – the essence of natural intelligence – is a biological universal. (shrink)

One of the possible solutions of the Fermi paradox is that all civilizations go extinct because they hit some Late Great Filter. Such a universal Late Great Filter must be an unpredictable event that all civilizations unexpectedly encounter, even if they try to escape extinction. This is similar to the “Death in Damascus” paradox from decision theory. However, this unpredictable Late Great Filter could be escaped by choosing a random strategy for humanity’s future development. However, if all civilizations act randomly, (...) this could be the actual cause of universal extinction, as no one will choose the most optimal strategy. Using a meta-random strategy, where the decision to start random actions is also made randomly, solves this. (shrink)

Stephen Hawking’s caution against messaging extraterrestrial intelligence is a claim of universal biology and is probably false.

Interest has been renewed in the study of consciousness, both theoretical and applied, following developments in 20th and early 21st-century logic, metamathematics, computer science, and the brain sciences. In this evolving narrative, I explore several theoretical questions about the types of artificial intelligence and offer several conjectures about how they affect possible future developments in this exceptionally transformative field of research. I also address the practical significance of the advances in artificial intelligence in view of the cautions issued by prominent (...) scientists, politicians, and ethicists about the possible dangers of such sufficiently advanced general intelligence, including by implication the search for extraterrestrial intelligence.

Based on the 1985 science fiction novel by the astronomer Carl Sagan, Contact tells the story of what a first encounter between humans and intelligent extraterrestrial beings might be like. It also details the complexities of faith and belief in a world where religion and science often come into conflict—a favorite theme of Sagan's, and a major subject in the history of philosophy. This chapter explores tangles of faith and belief through the lens of philosophy and the characters and concepts (...) of Contact. We pay special attention to Sagan's mouthpiece Ellie Arroway, who embodies the practice of doubting as essential to living a life rich in insight and meaning. While this is far from the sole philosophic quandary raised by the film, it is perhaps the central one. (shrink)

Why did God create a vast universe? Various answers are discussed and rejected: a) for its beauty; b) to instill a sense of the sublime in his intelligent creatures; c) to demonstrate his glory, d) to provide a home for extraterrestrial species; e) to guarantee that the natural emergence of (intelligent) life, though extremely rare, happens nonetheless somewhere; f) for no reason at all, because the human notion of efficiency does not apply to God’s actions. Instead, the paper suggests that (...) the universe is intended for Space settlements. Several objections to this proposal are considered and deemed unconvincing. (shrink)

This article investigates multi-species relations in a group of science fiction narratives featuring extraterrestrial beings, paying particular attention to the Alien movie series. The concept of “cosmopolitical ecology” is elaborated as a tool to map relations between the different kinds of beings that populate the modern imagination in SF, especially those between humans, machines, animals and alien entities. Two apparently opposing modes of relation are highlighted in the narratives: domestication and predation. But those modes, intrinsically connected to a broader colonial (...) imaginary, seem to be themselves entangled in complex ways. If modernity is marked by what Ghassan Hage calls “generalized domestication,” then what is the place of predation in modern metaphysics? An ambiguous position often attached to a dangerous other, the role of the predator also emerges as a feature of modern humans, a trace that they sometimes recognize in themselves when they look at an alien mirror.

The Convention of the Rights of the Person in Outer Space, more informally known as the Space Rights Convention, is a human rights and animal rights document that outlines basic principles, rights and freedoms bestowed to different categories of species in outer space which including on extraterrestrial bodies (both planetary and sub-planetary), synthetic bodies (e.g. space stations), as well as on spacecraft (both commissioned and uncommissioned) travelling through space itself (which is often referred to in the Convention as the interspace (...) (i.e. the space between terrestrial bodies). The Convention mirrors much of the rights outlined in the 1948 Universal Declaration of Human Rights but its purpose is to tailor those fundamental human rights to the context of spacefaring activity and to civilisations beyond planet Earth's atmosphere. The Convention was composed by Cometan and is published by the Astronist Institution alone on 23rd May 2022 and is scheduled to be republished as one of the preppendices of the Astrodoxy as its final major draft, after which only amendments may be made to its contents.

Abstract: This article examines risks associated with the program of passive search for alien signals (Search for Extraterrestrial Intelligence, or SETI) connected with the possibility of finding of alien transmission which includes description of AI system aimed on self-replication (SETI-attack). A scenario of potential vulnerability is proposed as well as the reasons why the proportion of dangerous to harmless signals may be high. The article identifies necessary conditions for the feasibility and effectiveness of the SETI-attack: ETI existence, possibility of AI, (...) small size of the Seed AI, small speed of physical interstellar travel and large distance between civilizations. Needed additions to the SETI protocol are considered: keep the signal existence, its content and source location in secret, don’t run alien programs, jam dangerous signals, wait until creation of humanity’s own AI. In addition, scenarios in which it may be reasonable to start an alien AI (if it has been downloaded) are explored. (shrink)

The Fermi Paradox has been intriguing scientists as it states that odds are indeed there must be some alien technologically advanced civilization capable of reaching Earth, or at least sending here unequivocal signs of intelligent life out there. Nonetheless, paradoxically, the more knowledge growth about exoplanets, stars and galaxies, the bigger is the frustration while searching something the like. In this brief essay, a possible explanation for Fermi's paradox gets grounded on Kant's Critique of Pure Reason.

Many global catastrophic risks are threatening human civilization, and a number of ideas have been suggested for preventing or surviving them. However, if these interventions fail, society could preserve information about the human race and human DNA samples in the hopes that the next civilization on Earth will be able to reconstruct Homo sapiens and our culture. This requires information preservation of an order of magnitude of 100 million years, a little-explored topic thus far. It is important that a potential (...) future civilization will discover this information as early as possible, thus a beacon should accompany the message in order to increase visibility. The message should ideally contain information about how humanity was destroyed, perhaps including a continuous recording until the end. This could help the potential future civilization to survive. The best place for long-term data storage is under the surface of the Moon, with the beacon constructed as a complex geometric figure drawn by small craters or trenches around a central point. There are several cost-effective options for sending the message as opportunistic payloads on different planned landers. (shrink)
