In an effort to inform the discussion surrounding existential risks from AI, we formulate Extinction-level Goodhart’s Law as “Virtually any goal specification, pursued to the extreme, will result in the extinction of humanity”, and we aim to understand which formal models are suitable for investigating this hypothesis. Note that we remain agnostic as to whether Extinction-level Goodhart’s Law holds or not. As our key contribution, we identify a set of conditions that are necessary for a model that (...) aims to be informative for evaluating specific arguments for Extinction-level Goodhart’s Law. Since each of the conditions seems to significantly contribute to the complexity of the resulting model, formally evaluating the hypothesis might be exceedingly difficult. This raises the possibility that whether the risk of extinction from artificial intelligence is real or not, the underlying dynamics might be invisible to current scientific methods. (shrink)

Some people feel distressed reflecting on human extinction. Some people even claim that our efforts and lives would be empty and pointless if humanity becomes extinct, even if this will not occur for millions of years. In this essay, I will attempt to demonstrate that this claim is false. The desire for long-lastingness or quasi-immortality is often unwittingly adopted as a standard for judging whether our efforts are significant. If we accomplish our goals and then later in life conclude (...) that these accomplishments were of no significance, then this is a sign that the desire for long-lastingness has crept into our standards. By recognizing this, and refraining from adopting an unreasonable standard to judge whether our efforts are significant, it will be to our advantage. Then, when we look back on life from an external perspective that encompasses times after humanity has become extinct, we will not conclude that our efforts amounted to nothing. Rather, we will conclude that many people made significant accomplishments that made their lives and the lives of other people better than they would have been if their goals had never been pursued.

“Existential risks” are risks that threaten the destruction of humanity’s long-term potential: risks of nuclear wars, pandemics, supervolcano eruptions, and so on. On standard utilitarianism, it seems, the reduction of such risks should be a key global priority today. Many effective altruists agree with this verdict. But how should the importance of these risks be assessed on a Christian moral theory? In this paper, I begin to answer this question – taking Thomas Aquinas as a reference, and the risks of (...) anthropogenic extinction as an example. I’ll suggest that on a Thomist framework, driving ourselves extinct would constitute a complete failure to fulfil our God-given nature, a radical form of hubris, and a loss of cosmological significance. So the reduction of such risks seems vital for Thomists, or Christians more broadly. Indeed, I end with the thought that these considerations are not parochially Christian, or indeed specifically religious: everyone with a similar view of mankind – as immensely valuable yet fallen and fragile – should agree that existential risks are a pressing moral concern.

Some people think that the inevitability of human extinction renders life meaningless. Joshua Seachris has argued that naturalism can be conceptualized as a meta-narrative and that it narrates across important questions of human life, including what is the meaning of life and how life will end. How a narrative ends is important, Seachris argues. In the absence of God, and with knowledge that human extinction is a certainty, is there any way that humanity could be meaningful and have (...) a good ending? I will distinguish between two conceptions of how humanity could be meaningful: the traditional view and an alternative view, which I will outline. I will argue that this alternative view provides a plausible explanation for how humanity could become meaningful. I will also argue that coming to terms with our mortality and other limitations would add meaning to human life and provide humanity with a good ending. (shrink)

Longtermism is the view that the most urgent global priorities, and those to which we should devote the largest portion of our resources, are those that focus on (i) ensuring a long future for humanity, and perhaps sentient or intelligent life more generally, and (ii) improving the quality of the lives that inhabit that long future. While it is by no means the only one, the argument most commonly given for this conclusion is that these interventions have greater expected goodness (...) per unit of resource devoted to them than each of the other available interventions, including those that focus on the health and well-being of the current population. In this paper, I argue that, even if we grant the consequentialist ethics upon which this argument depends, and even if we grant one of the axiologies that are typically paired with that ethics to give the argument, we are not morally required to choose an option that maximises expected utility; indeed, we might not even be permitted to do so. Instead, I will argue, if the argument's consequentialism is correct, we should choose using a decision theory that is sensitive to risk, and allows us to give greater weight to worse-case outcomes than expected utility theory does. And, I will show, such decision theories do not always recommend longtermist interventions. Indeed, sometimes, they recommend exactly the opposite: sometimes, they recommend hastening human extinction. Many, though not all, will take this as a reductio of the consequentialism or the axiology of the argument. I remain agnostic on the conclusion we should draw. (shrink)

Most current techniques to deal with invasive species are ineffective or have highly damaging side effects. To this end suppression-drives based on clustered regularly inter-spaced short palindromic repeats (CRISPR/Cas9) have been touted as a potential silver bullet for the problem, allowing for a highly focused, humane and cost-effective means of removing a target species from an environment. Suppression-drives come with serious risks, however, such that the precautionary principle seems to warrant us not deploying this technology. The focus of this paper (...) is on one such risk – the danger of a suppression-drive escaping containment and wiping out the target species globally. Here, I argue that in most cases this risk is significant enough to warrant not using a gene-drive. In some cases, however, we can bypass the precautionary principle by using an approach that hinges on what I term the ‘Worst-Case Clause’. This clause, in turn, provides us with a litmus test that can be fruitfully used to determine what species are viable targets for suppression-drives in the wild. Using this metric in concert with other considerations, I suggest that only three species are currently possible viable targets – the European rabbit, ship rat and Caribbean Tree Frog. (shrink)

This book defends an account of justice to nonhuman beings – i.e., to animals, plants etc. – also known as ecological or interspecies justice, and which lies in the intersection of environmental political theory and environmental ethics. More specifically, against the background of the current extinction crisis this book defends a global non-ranking biocentric theory of distributive ecological/interspecies justice to wild nonhuman beings, because the extinction crisis does not only need practical solutions, but also an account of how (...) it is the outcome of large-scale injustice. This book not only provides a novel theoretical framework that supports such a claim, but it also develops the theoretical tools to find just compromises between the entitlements of intraspecies and intra-human global distributive justice to ecological space for the purpose of working towards a vision of just conservation. -/- Content: 1.

This paper examines a recent argument in favour of strong precautionary action—possibly including working to hasten human extinction—on the basis of a decision-theoretic view that accommodates the risk-attitudes of all affected while giving more weight to the more risk-averse attitudes. First, we dispute the need to take into account other people’s attitudes towards risk at all. Second we argue that a version of the non-identity problem undermines the case for doing so in the context of future people. Lastly, we (...) suggest that we should not work to hasten human extinction, even if significant risk aversion is warranted. (shrink)

The cumulative impact of enhancement technologies may alter the human species in the very long-term future. In this article, I will start showing how radical genetic enhancements may accelerate the conversion into a novel species. I will also clarify the concepts of ‘biological species’, ‘transhuman’ and ‘posthuman’. Then, I will summarize some ethical arguments for creating a transhuman or posthuman species with a substantially higher level of well-being than the human one. In particular, I will present what I shall call (...) the Principle of the Best Interests of Posthumanity, which states that the enhancement of the human and transhuman species must be directed towards the creation of a posthuman existence that is substantially more valuable than its predecessors. I suggest that human extinction may be considered, within that principle, as one of the best interests of posthumanity. Finally, I will develop three objections that make that principle unattractive and that show that pursuing a full-blown programme of posthuman evolution is ethically flawed. (shrink)

In English, as in many other languages, male-gendered pronouns are sometimes used to refer not only to men, but to individuals whose gender is unknown or unspecified, to human beings in general (as in ―mankind‖) and sometimes even to females (as when the casual ―Hey guys‖ is spoken to a group of women). These so-called he/man or masculine generics have come under fire in recent decades for being sexist, even archaic, and positively harmful to women and girls; and advocates of (...) gender-neutral (or nonsexist) language have put forward serious efforts to discourage their use. Have they been successful, and to what extent? In this paper, I review some of the main arguments in favor of abolishing sexist male generics. I then present three studies tracking the use of he/man terminology in academic, popular, and personal discourse over the past several decades. I show that the use of these terms has fallen dramatically in recent years, while nonsexist alternatives have gradually taken their place. We may be paying witness to the early stages of the ultimate extinction of masculine generics. (shrink)

This review provides an overview of the ethics of extinctions with a focus on the Western analytical environmental ethics literature. It thereby gives special attention to the possible philosophical grounds for Michael Soulé’s assertion that the untimely ‘extinction of populations and species is bad’. Illustrating such debates in environmental ethics, the guiding question for this review concerns why – or when – anthropogenic extinctions are bad or wrong, which also includes the question of when that might not be the (...) case (i.e. which extinctions are even desirable). After providing an explanation of the disciplinary perspective taken (section “Introduction”), the concept of extinction and its history within that literature are introduced (section “Understanding extinction”). Then, in section “Why (or when) might anthropogenic extinctions be morally problematic?”, different reasons for why anthropogenic extinctions might be morally problematic are presented based on the loss of species’ value, harm to nonhuman individuals, the loss of valuable biological variety and duties to future generations. This section concludes by also considering cases where anthropogenic extinctions might be justified. Section “How to respond to extinctions?” then addresses a selection of topics concerning risks and de-extinction technologies. Finally, the section on “Extinction studies” introduces other viewpoints on the ethics of extinction from the extinction studies literature, followed by the “Conclusion”. (shrink)

Mosquito-borne diseases represent a significant global disease burden, and recent outbreaks of such diseases have led to calls to reduce mosquito populations. Furthermore, advances in ‘gene-drive’ technology have raised the prospect of eradicating certain species of mosquito via genetic modification. This technology has attracted a great deal of media attention, and the idea of using gene-drive technology to eradicate mosquitoes has been met with criticism in the public domain. In this paper, I shall dispel two moral objections that have been (...) raised in the public domain against the use of gene-drive technologies to eradicate mosquitoes. The first objection invokes the concept of the ‘sanctity of life’ in order to claim that we should not drive an animal to extinction. In response, I follow Peter Singer in raising doubts about general appeals to the sanctity of life, and argue that neither individual mosquitoes nor mosquitoes species considered holistically are appropriately described as bearing a significant degree of moral status. The second objection claims that seeking to eradicate mosquitoes amounts to displaying unacceptable degrees of hubris. Although I argue that this objection also fails, I conclude by claiming that it raises the important point that we need to acquire more empirical data about, inter alia, the likely effects of mosquito eradication on the ecosystem, and the likelihood of gene-drive technology successfully eradicating the intended mosquito species, in order to adequately inform our moral analysis of gene-drive technologies in this context.

When discussing the extinction of humanity, there does not seem to be any clear agreement about what ‘humanity’ really means. One aim of this paper is to show that it is a more slippery concept than it might at first seem. A second aim is to show the relationship between what constitutes or defines humanity and what gives it value. Often, whether and how we ought to prevent human extinction depends on what we take humanity to mean, which (...) in turn depends on what we value about humans. Finally, I will offer a definition of humanity that I argue offers a plausible account of when we might say humanity has gone extinct, and reflects what we value about humans, and relatedly, what many actually care about in terms of why we should be preserved.

Our Earth’s climate is changing. Any species living in the Earth’s ecosystem need to thrive to adapt to the new living conditions. Otherwise, extinction will be their outcome. In the race for adaptation, waterbirds (Aequorlitornithes), such as penguins, cormorants, and alcids, seem disadvantageous.

This paper addresses two problems concerning the deferred ostension of extinct and fictive kinds. First, the sampled item, the fossil or the depiction, is not a sample of the referent. Nonetheless, the retained characteristic shape, understood via analogy with living creatures, enables the reference to be fixed. Second, though both extinct and fictive kinds are targets of deferred ostension, there is an important difference in the sample. Fossilization is a natural causal process that makes fossils to be reflections of their (...) originals. As reflections, fossils embed their referents in the primary existential world of perceived things. Images of artificial kinds, by contrast, leave their referents in the secondary existential world of mere appearance. In this way, the paper widens the scope of the Kripke-Putnam account of ostension for naming kinds by drawing on Quine’s concept of deferred ostension for absent referents. (shrink)

De-extinction is the process through which extinct species can be brought back into existence. Although these projects have the potential to cause great harm to animal welfare, discussion on issues surrounding de-extinction have focussed primarily on other issues. In this paper, I examine the potential types of welfare harm that can arise through de-extinction programs, including problems with cloning, captive rearing and re-introduction. I argue that welfare harm should be an important consideration when making decisions on de- (...) class='Hi'>extinction projects. Though most of the proposed benefits of these projects are insufficient to outweigh the current potential welfare harm, these problems may be overcome with further development of the technology and careful selection of appropriate species as de-extinction candidates.

The aim of this investigation is to answer the question of why it is prima facie morally wrong to cause or contribute to the extinction of species. The first potential answer investigated in the book is that other species are instrumentally valuable for human beings. The results of this part of the investigation are that many species are instrumentally valuable for human beings but that not all species are equally valuable in all cases. The instrumental values of different species (...) also have to compete with other human values. Sometimes these other values probably outweigh the value of the continued existence of the species. In general the degree of uncertainty is very high and the precautionaty principle is recommended to deal with these uncertainties. We also found that we have a duty to consider the interests of future generations of human beings and that these duties, in general, speak in favour of preservation. Anthropocentric instrumentalism therefore provides us with rather strong reasons to consider many cases of human caused extinction as prima facie morally wrong. Even so, anthropocentric instrumentalism does not fully account for the moral intuition we set out to investigate. The next potential answer that is investigated in the book is that species have a moral standing in their own right. The result of this part of the investigation is that this idea is highly unlikely, in particular because species cannot have any interests to consider. Anotgher potential answer is that species have intrinsic value in some other meaning that does not imply moral standing. We concluded that it is possible to be subjectively valued as an end and that many species have properties that make them highly suitable for being valued as ends by human beings. Finally, we found that our contributions to the extinction of species in most cases frustrate the interests of many non-human sentient beings. This is true if the species in question is made up of sentient individuals, and it is also true when the species in question is made up of non-sentient individuals that have instrumental value for sentient individuals of other species. There are exceptions to this rule, but all in all it seems that the inclusion of non-human sentient individuals together with us humans as moral objects, in most cases, tip the scale drastically in favour of preservation. The main result of the investigation is that there is not one but several explanations to why it is prima facie morally wrong to contribute to the extinction of species – and all of them are about duties to respect the interests of individual sentient animals, including human beings.

Nick Bostrom’s recently patched ‘‘simulation argument’’ (Bostrom in Philos Q 53:243–255, 2003; Bos- trom and Kulczycki in Analysis 71:54–61, 2011) purports to demonstrate the probability that we ‘‘live’’ now in an ‘‘ancestor simulation’’—that is as a simulation of a period prior to that in which a civilization more advanced than our own—‘‘post-human’’—becomes able to simulate such a state of affairs as ours. As such simulations under consid- eration resemble ‘‘brains in vats’’ (BIVs) and may appear open to similar objections, the (...) paper begins by reviewing objections to BIV-type proposals, specifically those due a presumed mad envatter. In counter example, we explore the motivating rationale behind current work in the development of psychologically realistic social simula- tions. Further concerns about rendering human cognition in a computational medium are confronted through review of current dynamic systems models of cognitive agency. In these models, aspects of the human condition are repro- duced that may in other forms be considered incomputable, i.e., political voice, predictive planning, and consciousness. The paper then argues that simulations afford a unique potential to secure a post-human future, and may be nec- essary for a pre-post-human civilization like our own to achieve and to maintain a post-human situation. Long-s- tanding philosophical interest in tools of this nature for Aristotle’s ‘‘statesman’’ and more recently for E.O. Wilson in the 1990s is observed. Self-extinction-level threats from State and individual levels of organization are compared, and a likely dependence on large-scale psychologically realistic simulations to get past self-extinction-level threats is projected. In the end, Bostrom’s basic argument for the conviction that we exist now in a simulation is reaffirmed. (shrink)

Psychoneural reductionists sometimes claim that sufficient amounts of lower-level explanatory achievement preclude further contributions from higher-level psychological research. Ostensibly, with nothing left to do, the effect of such preclusion on psychological explanation is extinction. Reductionist arguments for preclusion have recently involved a reorientation within the philosophical foundations of neuroscience---namely, away from the philosophical foundations and toward the neuroscience. In this chapter, I review a successful reductive explanation of an aspect of reward function in terms of dopaminergic operations of the (...) mesocorticolimbic system in order to demonstrate why preclusion/extinction claims are dubious.

The book contains the first part of an investigation aimed at finding out why it is morally wrong to cause species to go extinct. That it is morally wrong seems to be a very basic and widely held intuition. It seems reasonable that a moral theory worth taking seriously ought to be able to account for that intuition. The most common attempt to answer our question is to refer to the instrumental value of the species for human beings – the (...) anthropocentric instrumental approach as I have chosen to call it. This is the answer that is discussed in this book. We have found many ways in which different species have instrumental value for human beings – both individually and as a part of ecosystems and of biodiversity in general. We could not guarantee however that this includes all species. In some cases, it also turned out that the instrumental value of the species in fact favours exploitation maybe even as far to the extinction of the species. We also noticed that there is no guarantee that the instrumental value of the species can always outweigh the competing values that we would gain by different encroachments that contribute to the extinction of the species. We found however that there are some special circumstances that help push the scale in the direction of preservation. I am thinking of some particular types of value such as choice value and transformation value – values that in general seem to favour preservation of species. This principle shows us that it would be rational from an anthropocentric instrumental vantage point to rule in favour of preservation in many of the cases where we are uncertain about the value of the species, about the best way of utilising the value, or about the connection between the species and other species or biodiversity in general. I am finally thinking of the moral principle that we have duties to consider the future interests of generations to come. We found that with a few exceptions it is justified to adopt such a principle. This in combination with the principles of precaution ought in general to urge us not to cause the extinction of species unless we have very trustworthy evidence that they will not turn out to be more valuable alive to future generations in comparison to what we can get from driving them to extinction. In relation to the discussion about the value of other species for human beings, it is worth noticing that all the arguments we have found in favour of preservation would be even stronger – and therefore account even better for the intuition that it is at least prima facie wrong to cause extinction – if we also accepted that other entities than human beings can have moral standing. Finally, we noticed that our moral intuitions strongly indicate that even in the cases where the instrumental value of other species for human beings talks in favour of preservation, there is still something lacking. Something we have to account for in order to totally account for our moral intuition against extinction. The conclusion will have to be that anthropocentric instrumentalism is in favour of preservation in many cases – probably in more cases than is generally acknowledged – but that it is not enough to give a complete account of the intuition that it is prima facie morally wrong to contribute to the extinction of species. We therefore have to continue our search for such an account. (shrink)

The rediscovery of the silver-backed chevrotain, an endemic species to Vietnam, in 2019, after almost 30 years of being lost to science, is a remarkable outcome for the global conservation agenda. However, along with the happiness, there is a tremendous concern for the conservation of the species as eating wildmeat, including chevrotain, is deeply rooted in the socio-cultural values of Vietnamese. Meanwhile, conservation plans face multiple obstacles since the species has not been listed in the list of endangered, precious, and (...) rare wildlife prioritized for protection and is still classified by the IUCN as lacking data. Given the limited effectiveness of conservation measures, this essay discusses the determining roles of local actions, community cooperation, and humanistic values oriented toward eco-surplus culture in addressing the global biodiversity conservation agenda, specifically the conservation of the silver-backed chevrotain. Local actions and community cooperation for conservation can be actualized to achieve conservation goals through citizen and community sciences, integration of modern technologies (e.g., Internet, crowdfunding platforms, social media, AI, etc.), and the bonding capability of humanistic values that prioritize environmental healing. Communicating conservation information to the community, especially the children, has to stimulate their thinking and imagination about nature, develop their curiosity and desire to protect wildlife, and eventually build eco-surplus core values in their mindsets. To successfully awaken the humanistic values within the community and incorporate them into conservation endeavors, the conservation message with the name “mouse-deer”, “chevrotain”, or scientific name (Tragulus versicolor) is largely insufficient as they show an unfamiliar feeling. Therefore, we suggest calling the mouse-deer “cheo cheo”, a local name that can create familiarity and closeness, awaken the environmental conscience and humanistic values, and stimulate thinking and imagination. All these factors are essential for conservationists, scientists, and the government to support the community in building the eco-surplus culture. (shrink)

Are the methods of synthetic biology capable of recreating authentic living members of an extinct species? An analogy with the restoration of destroyed natural landscapes suggests not. The restored version of a natural landscape will typically lack much of the aesthetic value of the original landscape because of the different historical processes that created it—processes that involved human intentions and actions, rather than natural forces acting over millennia. By the same token, it would appear that synthetically recreated versions of extinct (...) natural organisms will also be less aesthetically valuable than the originals; that they will be, in some strong sense, ‘inauthentic’, because of their peculiar history and mode of origin. I call this the ‘genesis argument’ against de-extinction. In this article I critically evaluate the genesis argument. I highlight an important disanalogy between living organisms and natural landscapes: viz., it is of the essence of the former, but not of the latter, to regularly reproduce and die. The process of iterated natural reproduction that sustains the continued existence of a species through time obviously does not undermine the authenticity of the species. I argue that the authenticity of a species will likewise be left intact by the kind of artificial copying of genes and traits that a de-extinction project entails. I conclude on this basis that the genesis argument is unsound. (shrink)

In both scientific and popular circles it is often said that we are in the midst of a sixth mass extinction. Although the urgency of our present environmental crises is not in doubt, such claims of a present mass extinction are highly controversial scientifically. Our aims are, first, to get to the bottom of this scientific debate by shedding philosophical light on the many conceptual and methodological challenges involved in answering this scientific question, and, second, to offer new (...) philosophical perspectives on what the value of asking this question has been — and whether that value persists today. We show that the conceptual challenges in defining ‘mass extinction’, uncertainties in past and present diversity assessments, and data incommensurabilities undermine a straightforward answer to the question of whether we are in, or entering, a sixth mass extinction today. More broadly we argue that an excessive focus on the mass extinction framing can be misleading for present conservation efforts and may lead us to miss out on the many other valuable insights that Earth’s deep time can offer in guiding our future.

Variation, adaptation, heredity and fitness, constraints and affordances, speciation, and extinction form the building blocks of the (Neo-)Darwinian research program, and several of these have been called “Darwinian principles.” Here, we suggest that caution should be taken in calling these principles Darwinian because of the important role played by reticulate evolutionary mechanisms and processes in also bringing about these phenomena. Reticulate mechanisms and processes include symbiosis, symbiogenesis, lateral gene transfer, infective heredity mediated by genetic and organismal mobility, and hybridization. (...) Because the “Darwinian principles” are brought about by both vertical and reticulate evolutionary mechanisms and processes, they should be understood as foundational for a more pluralistic theory of evolution, one that surpasses the classic scope of the Modern and the Neo-Darwinian Synthesis. Reticulate evolution moreover demonstrates that what conventional (Neo-)Darwinian theories treat as intra-species features of evolution frequently involve reticulate interactions between organisms from very different taxonomic categories. Variation, adaptation, heredity and fitness, constraints and affordances, speciation, and extinction therefore cannot be understood as “traits” or “properties” of genes, organisms, species, or ecosystems because the phenomena are irreducible to specific units and levels of an evolutionary hierarchy. Instead, these general principles of evolution need to be understood as common goods that come about through interactions between different units and levels of evolutionary hierarchies, and they are exherent rather than inherent properties of individuals.

Existence value refers to the value humans ascribe to the existence of something, regard­less of whether it is or will be of any particular use to them. This existence value based on preference satisfaction should be taken into account in evaluating activities that come with a risk of species extinction. There are two main objections. The first is that on the preference satisfaction interpretation, the concept lacks moral importance because satisfying people’s preferences may involve no good or well-being for (...) them. However, existence value can be based on a restricted version of the preference satisfaction theory, which is not vulnerable to the skeptical arguments about the link between preference satisfaction and well-being. The second objection is that even if preference satisfaction can be linked to well-being, understanding existence value in terms of individual preference satisfaction is incoherent, because existence value reflects disinterested preferences that involve no benefits to the individual. However, the fact that existence value may involve disinterested preferences does not threaten the coherence of the concept, but suggests that it does not fit smoothly into the “utilitarian” or “welfarist” framework it is commonly considered within. A pluralistic normative approach based on prima facie duties can be an alternative to standard utilitarian-style approaches for considering existence value in concrete cases involving a risk of species extinction, such as through deep sea mining.

A number of influential biologists are currently pursuing efforts to restore previously extinct species. But for decades, philosophers of biology have regarded “de-extinction” as conceptually incoherent. Once a species is gone, it is gone forever. We argue that a range of metaphysical, biological, and ethical grounds for opposing de-extinction are at best inconclusive and that a pragmatic stance that allows for its possibility is more appealing.

Recently, we have witnessed an explosion of studies and discussions claiming that Neanderthals engaged in a range of “symbolic” behaviors, including personal ornament use (Radovčić et al., 2015), funerary practices (Balzeau et al., 2020), visual arts (Hoffmann et al., 2018), body aesthetics (Roebroeks et al., 2012), etc. In Paleolithic archaeology, it has become mainstream to axiomatically infer from these putative behaviors that Neanderthals engaged in symbol use and that Neanderthals thus possessed some form of language. Rudolf Botha's bombastic title "Neanderthal (...) Language: Demystifying the Linguistic Powers of Our Extinct Cousins" provides a detailed and very critical overview of the archaeological hypotheses and speculations about Neanderthal language.

In his celebrated 1974 essay “What Is It Like to Be a Bat?,” Thomas Nagel stages a human-bat encounter to illustrate and support his claim that “subjective experience” is irreducible to “objective fact”: because Nagel cannot experience the world as a bat does, he will never know what it is like to be one. In Nagel’s account, heterogeneity is figured negatively—as a failure or lack of resemblance—and functions to constrain his knowledge of bats. Today, as white-nose syndrome threatens bat populations (...) across North America, might figuring heterogeneity positively, as a condition of creativity, open up new modes of receptivity and responsiveness to species extinctions? This essay turns to philosophies of becoming and to recent research in the biological sciences to explore this possibility. I suggest that attending to the heterogeneity of experience alerts us to more public dimensions of our being and may thereby work against the tendency to understand and experience ourselves as self-contained and closed off from one another and the world we share in common. This may in turn enhance our sense of entanglement with the events, bodies, and forces on the “outside” of experience, including bats and the white-nose syndrome with which they are afflicted today. Such an affirmation of heterogeneity as a condition of creativity holds the greatest promise for multispecies ethics today, I propose, when it is joined to an affirmation of incompatibilities within and between things as a real force of suffering and destruction in a heterogeneous world.

Scientific enterprise is a part and parcel of the contemporaneous to it general human cultural and, even more general, existential endeavor. Thus, the fundamental for us notion of evolution, in the modern sense of this characteristically Occidental term, appeared in the 19-th century, with its everything pervading, irreversible cultural and technological change and the existential turmoil. Similarly, a formerly relatively recherché word emergence, became a widely used scientific term only in the 20-th century, with its cultural, economical, political, and national (...) sagas of emergence and destruction played against a background of the universe emerging from the Big Bang and disappearing into its black holes, if not into its ultimate Big Collapse. Today, the rules of engagement in scientific emergence-evolution games, steadily spreading from natural to cognitive sciences, and beyond, are dominated by the 19-th century concept of natural selection which has inverted the time-arrow of the classical creationist dogma, with its rarely spelled out pessimistic implication that the life is moving from the highest biological organization to an entropic chaos. In its turn, the natural selection’s excessively contagious, “do-it-yourself” optimism might ultimately turn out to be its undoing : the natural selection conjecture, when transposed to such fields as linguistics from the strictly biological scene, with its times of engagement ranging from at most hundred years of life expectancy for an individual organism to at least millions and even billions of years for evolutionary processes to bring this or that organism to existence, becomes for the first time verifiable and even falsifiable. The present paper studies some implications of the well-known but almost universally disregarded tight combinatorial morphological-semantic structure of the verbal system of Biblical Hebrew, to show that this linguistic fossil testifies to the existence of a now extinct Proto-Language whose extremely tight verbal organization and meaningful architecture made it both structurally strikingly similar and expressively vastly superior to humanly designed Assembler languages, – an absolutely novel, paradoxical phenomenon, never before and nowhere else observed and apparently incompatible with the basic tenets of modern linguistic natural selection theories and, at the very least, crying out for new explanatory linguistic paradigms.

Katz denies that organisms created in a lab as part of a de-extinction attempt will be authentic members of the extinct species, on the basis that they will lack the original species’ defining biological and evolutionary history. Against Katz, I note that an evolutionary lineage is conferred on an organism through its inheriting genes from forebears already possessed of such a lineage, and that de-extinction amounts to a delayed, human-assisted reproductive process, in which genes are inherited from forebears (...) long dead. My conclusion is that de-extinct organisms can perfectly well have an ancient evolutionary history, contrary to what Katz claims. (shrink)

Media reporters often announce that we are on the verge of bringing back the woolly mammoth, even while there is growing consensus among scientists that resurrecting the mammoth is unlikely. In fact, current “de-extinction” efforts are not designed to bring back a mammoth, but rather adaptations of the mammoth using close relatives. For example, Harvard scientists are working on creating an Asian elephant with the thick coat of a mammoth by merging mammoth and elephant DNA. But how should such (...) creatures be classified? Are they elephants, mammoths, or both? Answering these questions requires getting clear about the concept of reproduction. What I hope to show is that with an appropriate notion of reproduction—one for which I will argue—resurrecting a member of Mammuthus primigenius is a genuine possibility. (shrink)

According to an intriguing though somewhat enigmatic line of thought first proposed by Jonathan Bennett, if humanity went extinct any time soon this would be unfortunate because important business would be left unfinished. This line of thought remains largely unexplored. I offer an interpretation of the idea that captures its intuitive appeal, is consistent with plausible constraints, and makes it non-redundant to other views in the literature. The resulting view contrasts with a welfare-promotion perspective, according to which extinction would (...) be bad because it would come at a massive opportunity cost in terms of feasibly achievable welfare over the lifetime of our species.

The Biblical story of the Art (a floating, zoo-like device, constructed to survive climate turmoil and mass extinction) can be regarded as an archetypal image (in the terminology of Gaston Bachelard), capturing structural components of the human-animal relationship. Building on the contributions by Larson and Barr, Keulartz, Bovenkerk and Verweij, and Ramp and Bekoff, I will argue that, in the course of history, the Ark has evolved from a fictional (imaginary) icon into something increasingly real. The agricultural village of (...) the Neolithic era already functioned as a sheltered enclave, a survival machine designed to allow a select number of humans and accompanying species to withstand environmental fluctuations and survival pressure. In the current situation, however, the Ark has developed into a Gestell of planetary dimensions. The concept of the anthropocene basically conveys the idea that we have entered a global symbolical Ark, conceptualised by Teilhard de Chardin as the noosphere (the world-wide web of intelligence and policies, technologies and engineering, research and regulations) and emerging against the backdrop of a necro(s)cene: an ambiance of mass extinction. Increasingly, prospects for survival of a disconcertingly large number of species depend on human behaviour and human decision: on our ability or failure to collectively address the daunting challenges of the present.

This article provides the foundation for a new predictive theory of animal learning that is based upon a simple logical model. The knowledge of experimental subjects at a given time is described using logical equations. These logical equations are then used to predict a subject’s response when presented with a known or a previously unknown situation. This new theory suc- cessfully anticipates phenomena that existing theories predict, as well as phenomena that they cannot. It provides a theoretical account for phenomena (...) that are beyond the domain of existing models, such as extinction and the detection of novelty, from which “external inhibition” can be explained. Examples of the methods applied to make predictions are given using previously published results. The present theory proposes a new way to envision the minimal functions of the nervous system, and provides possible new insights into the way that brains ultimately create and use knowledge about the world.

Deep Ecology, the Voluntary Human Extinction Movement (VHEMT), and Anti-Civilization Primitivism have frequently been labeled as radical environmental ideologies, owing to their relationship with activities conducted by environmental extremists. Nonetheless, given the serious concerns faced by climate change and biodiversity loss, it is critical to engage with a broad range of perspectives and techniques. Such participation allows us to have access to a greater range of perspectives and a more diverse pool of knowledge, boosting our capacity for creative problem-solving. (...) The purpose of this essay is to reconsider the underlying concepts and principles that drive these theories, as well as to assess their relevance in tackling modern environmental issues. We think that Deep Ecology, the Voluntary Human Extinction Movement (VHEMT), and Anti-Civilization Primitivism should be called "unconventional" or "distinctive" rather than "radical," because they primarily focus on the ontological perspective but do not urge extreme acts. Meanwhile, their distinctiveness helps increase public awareness about environmental issues and promote reflection on and rethinking of the ontological link between mankind and the natural world.

In this critique of longtermism, I attack its Heart, the idea that there is intrinsic value in the addition of each new happy being to the world. I provide new responses to longtermists' two main arguments for the Heart (The Argument from Extinction and The Argument from Miserable Beings). I then sketch an alternative view to longtermism, which I call Future Sentimentalism, a view that does a better job of explaining our future-regarding reasons. Finally, I consider an important objection (...) to my critique. (shrink)

Scientists have been arguing for more than 25 years about whether it is a good idea to collect voucher specimens from particularly vulnerable biological populations. Some think that, obviously, scientists should not be harvesting organisms from, for instance, critically endangered species. Others think that, obviously, it is the special job of scientists to collect precisely such information before any chance of retrieving it is forever lost. The character, extent, longevity, and span of the ongoing disagreement indicates that this is likely (...) to be a hard problem to solve. Nonetheless, the aim of this paper is to help field biologists figure out what do to when collecting a voucher specimen risks extinction. Here I present and assess varying practices of specimen collection for both extant and extinct species in order to compare and contrast cases where extinction risk both is and is not a problem. When it comes to taking vouchers from extant species at some risk of extinction, I determine that those advocating for conservative approaches to collection as well as those advocating for liberal information-gathering practices have good reasons to assess things in the way they each do. This means that there is unlikely to be a decisive, one-size-fits-all response to this problem. Still, progress can be made. We can acknowledge the risks of proceeding in either manner, as well as the uncertainty about how best to proceed. We can proceed as thoughtfully as possible, and be ready to articulate a rationale for whichever procedure is used in any particular case. (shrink)

If it is within our power to provide a significantly better world for future generations at a comparatively small cost to ourselves, we have a strong moral reason to do so. One way of providing a significantly better world may involve replacing our species with something better. It is plausible that in the not‐too‐distant future, we will be able to create artificially intelligent creatures with whatever physical and psychological traits we choose. Granted this assumption, it is argued that we should (...) engineer our extinction so that our planet's resources can be devoted to making artificial creatures with better lives. (shrink)

In this article, the notion of entropology introduced by Claude Lévi-Strauss is applied and developed in the context of Georges Bataille’s anthropological philosophy: Bataille’s project is defined as entropological. Four philosophical vectors are chosen for this: the theory of general economy, the concept of decay, the idea of extinction and the notion of inhumanism. The theory of general economy allows us to understand the immanent terrestrial nature of humanity and the negative – entropic – side of the capitalist economy. (...) The concept of decay gives access to the thought of bodily disintegration and decomposition, which is temporality and mortality that split the subject. The idea of extinction speculates on the consequences of humanity’s destructiveness, libidinally charged inertia, and the extreme perspective of entropy’s impact on the planet. The notion of inhumanism suggests a radical rethinking of the human relationship with alienation and exteriority: Bataille’s philosophy is reinterpreted as inhumanist. I conclude that the Lévi-Strauss’s neologism – entropology – can be productively articulated and actualised within the framework of Bataille’s philosophy. (shrink)

Globally, languages are disappearing at an unprecedented rate. To establish successful strategic options on how to protect the language's survival, members of linguistic communities must be knowledgeable of the reasons for language extinction or endangerment. This paper discusses how the number of people who speak Pangasinan, which is the eighth most common language in the Philippines, is decreasing over time and how this is affecting the language. It gives an outline of the Pangasinan language's current vitality and covers the (...) Philippines' language policy history. It also considers a situation in which globalization may provide unexpected chances for language revitalization. This study seeks to serve as a springboard for future research and aids teachers and other relevant educational personnel in identifying, comprehending, assessing, and implementing appropriate language-endangerment remedies. The authors also provide suggestions for future research based on their findings. (shrink)

Current planetary defense policy prioritizes a probability assessment of risk of Earth impact by an asteroid or a comet in the planning of detection and mitigation strategies and in setting the levels of urgency and budgeting to operationalize them. The result has been a focus on asteroids of Tunguska size, which could destroy a city or a region, since this is the most likely sort of object we would need to defend against. However a complete risk assessment would consider not (...) only the probability of an impact but also the magnitude of its consequences, which in the case of an object of Chicxulub size could be the end of civilization or even human extinction. This paper argues that a planetary defense policy based on a complete (or one could say genuine) risk assessment would justify expenditures much higher than at present. (shrink)

David Benatar claims that everyone was seriously harmed by coming into existence. To spare future persons from this suffering, we should cease having children, Benatar argues, with the result that humanity would gradually go extinct. Benatar’s claim of universal serious harm is baseless. Each year, an estimated 94% of children born throughout the world do not have a serious birth defect. Furthermore, studies show that most people do not experience chronic pain. Although nearly everyone experiences acute pain and discomforts, such (...) as thirst, these experiences have instrumental value. For example, when a person picks up a hot object, in response to the pain, the person releases the object, thereby preventing serious harm. The standard that Benatar uses to evaluate the quality of our lives is arbitrary, as I will demonstrate. His proposal that we phase humanity out of existence by ceasing to have children is misguided and an overreaction to the problem of human suffering. The ‘threshold conception of harm’, which is a targeted approach for preventing future persons from suffering, is a more sensible approach. (shrink)

We know that Homo sapiens will not exist forever. Given this, how should our species end? What are the reasons, if any, to delay our extinction? In this paper, I show that the pre-eminent reasons which favour prolonging the existence of the species are partial: they will arise from the particular attachments and projects of the final few generations. While there may also be impartial reasons to prolong the species, these reasons are liable, with time, to reverse their valence: (...) we can be reasonably confident that they will ultimately recommend hastening the demise of the species. Consequently, it is likely that our descendants will eventually face a difficult -- possibly tragic -- conflict, between partial duties that recommend living on, and an impartial duty to extinguish the species.

The intuition of neutrality, as discussed by John Broome, says that the addition of people does not, by itself, produce or subtract value from the world. Such intuition allows us to disregard the effects of climate change policy onto the size of populations, effectively allowing us to make policy recommendations. Broome has argued that the intuition has to go. Orsi responds by urging a normative (rather than Broome's axiological) interpretation of neutrality in terms of an exclusionary permission to disregard the (...) value of adding lives. He explores justifications and limits of such permission by referring to the prospect of human extinction. (shrink)

Political actions by Fridays for Future, Extinction Rebellion, and other climate activists often involve violations of legal regulations – such as compulsory education requirements or traffic laws – and have been criticized for this in the public sphere. In this essay, I defend the view that these violations of the law constitute a form of morally justified civil disobedience against climate policies. I first show that these actions satisfy the criteria of civil disobedience even on relatively strict conceptions of (...) civil disobedience. I then argue that they meet plausible justification conditions for civil disobedience because they are directed against serious and clear injustices, which legal means of influence have failed to remedy for decades. Finally, I reject the objection that civil disobedience against climate policy violates basic democratic principles because it claims authority to override democratically enacted agreements. When addressed to Fridays for Future activists, the objection misfires for the reason alone that these activists are largely minors that are excluded from democratic participation. Moreover, disobedience even by adult activists is justified by the existence of serious democratic deficits in our climate policies, especially since it can help to correct them. Such deficits include the lack of representation of the interests of people affected by climate change in the future and globally. (shrink)

Person-affecting views in population ethics state that (in cases where all else is equal) we’re permitted but not required to create people who would enjoy good lives. In this paper, I present an argument against every possible variety of person-affecting view. The argument takes the form of a dilemma. Narrow person-affecting views must embrace at least one of three implausible verdicts in a case that I call ‘Expanded Non-Identity.’ Wide person-affecting views run into trouble in a case that I call (...) ‘Two-Shot Non-Identity.’ One plausible practical upshot of my argument is as follows: we individuals and our governments should be doing more to reduce the risk of human extinction this century.

The visuospatial system integrates inner and outer functional processes, organizing spatial, temporal, and social interactions between the brain, body, and environment. These processes involve sensorimotor networks like the eye–hand circuit, which is especially important to primates, given their reliance on vision and touch as primary sensory modalities and the use of the hands in social and environmental interactions. At the same time, visuospatial cognition is intimately connected with memory, self-awareness, and simulation capacity. In the present article, we review issues associated (...) with investigating visuospatial integration in extinct human groups through the use of anatomical and behavioral data gleaned from the paleontological and archaeological records. In modern humans, paleoneurological analyses have demonstrated noticeable and unique morphological changes in the parietal cortex, a region crucial to visuospatial management. Archaeological data provides information on hand–tool interaction, the spatial behavior of past populations, and their interaction with the environment. Visuospatial integration may represent a critical bridge between extended cognition, self-awareness, and social perception. As such, visuospatial functions are relevant to the hypothesis that human evolution is characterized by changes in brain–body–environment interactions and relations, which enhance integration between internal and external cognitive components through neural plasticity and the development of a specialized embodiment capacity. We therefore advocate the investigation of visuospatial functions in past populations through the paleoneurological study of anatomical elements and archaeological analysis of visuospatial behaviors.

This is a commentary on Andrea Lavazza and Murilo Vilaça's article "Human Extinction and AI: What We Can Learn from the Ultimate Threat" (Lavazza & Vilaça, 2024). I discuss the potential concern that their proposal to create artificial successors to "insure" against the tragedy of human extinction might mean being too quick to accept that catastrophic prospect as inevitable, rather than single-mindedly focusing on avoiding it. I also consider the question of the value that we might reasonably assign (...) to such a future of artificial successors under the assumption that they do not enjoy phenomenal consciousness. (shrink)
