It strikes many as obvious that negative facts—such as that Justin Trudeau is not the prime minister of Australia—are not fundamental: negative facts must ultimately be explained in terms of positive facts (for instance, that Justin Trudeau is the prime minister of Canada). I focus on a particular class of negative facts: contingent negative existentials (such as that there are no 10ft tall humans). If contingent negative existentials are not fundamental, then they must be explained. But the claim (...) that contingent negative existentials are explained is in tension with the widely held view that any universal generalization can be explained by its instances together with a totality fact (i.e. a fact to the effect that the instances exhaust the relevant domain). This is because a totality fact is itself a negative existential, and equivalent to a universal generalization. If the explanation for any contingent negative existential must appeal to another contingent negative existential, then—unless there are no fundamental facts—not all contingent negative existentials can be non-fundamental. I argue that we should give up the age-old mantra that only positive facts can be fundamental. I show that at least some contingent negative existentials are fundamental. I first make the case for including a totality fact in the explanans for a contingent negative existential and show that alternative accounts for explaining such facts are inadequate. I then undermine the standard arguments for subscribing to the view that there are no negative facts—including negative existentials—at the fundamental level. (shrink)

In this essay I address the question, “What is the subject matter of phenomenological research?” I argue that in spite of the increasing popularity of phenomenology, the answers to this question have been brief and cursory. As a result, contemporary phenomenologists lack a clear framework within which to articulate the aims and results of their research, and cannot easily engage each other in constructive and critical discourse. Examining the literature on phenomenology’s identity, I show how the question of phenomenology’s subject (...) matter has been systematically neglected. It has been overshadowed by an unending concern with phenomenology’s methodological identity. However, an examination of recent contributions to this literature reveals that a concern with articulating phenomenology’s subject matter has gradually increased, although such articulations remain preliminary. In light of this, I delineate, define, and illustrate three layers of phenomenological research, which I term “existentials,” “modes,” and “prejudices.” While the delineation of these layers is drawn primarily from classical phenomenological texts, they are defined and illustrated through the use of more contemporary literature. Following the articulation of this subject matter, I briefly consider some of the debates—both foundational and applied—that can be facilitated by the adoption of this framework. (shrink)

Fictional characters present a problem for semantic theorists. One approach to this problem has been to maintain realism regarding fictional characters, that is to claim that fictional characters exist. In this way names originating from fiction have designata. On this approach the problem of negative existentials is more pressing than it might otherwise be since an explanation must be given as to why we judge them true when the names occurring within them designate existing objects. So, realists must explain (...) the intuitive truth of such statements. Some realists have appealed to pragmatics to explain this, but have not developed these positions fully. What follows is an original account of negative existentials based on the pragmatic process of modulation. Modulation affects the meaning of ‘exists’ such that its extension is merely those things that exist physically. It is then argued that the modulation approach provides a more natural account of the intuitive truth of negative existentials involving fictional characters than an account based on conversational implicatures. Finally, the modulation account is defended against objections presented against similar accounts. (shrink)

Realist theories about fictional entities must explain the fact that, in ordinary contexts people deny, apparently in all seriousness, that there are such things as the Big Bad Wolf and Santa Claus. The usual explanation treats these denials as involving restricted quantification: The speaker is said to be denying only that the Big Bad Wolf and Santa Claus are to be found among real or actual things, not that there are no such things at all. This is unconvincing. The denials (...) may just as naturally be phrased as “The Big Bad Wolf and Santa Claus don't exist”, and claims of nonexistence seem not to admit of interpretations corresponding to statements of restricted quantification. Ordinary denials of the existence of fictional entities constitute a severe difficulty for realist theories. (shrink)

To solve the referential sub-problem of negative existentials one must explain why we interpret uses of, e.g., ‘Sherlock Holmes doesn’t exist’ as saying something coherent and intuitively true, even though the speaker purports to refer to something. Pragmatic Meinongism solves this problem by allowing ‘does not exist’ to be pragmatically modulated to express an inclusive sense under which it can be satisfied by something. I establish three points in defense of pragmatic Meinongism: (i) it is superior to Russell-inspired solutions; (...) (ii) it is supported by independent evidence of pragmatic modulation; and (iii) it requires no dubious ontological commitments. (shrink)

Attempts to analyze negative existential statements face the following familiar problem. If a negative existential statement—say, “Hamlet does not exist” or “the golden mountain does not exist”—is true, its subject term must lack an object of reference. But, absent such an object, it seems that nothing true or false can be said about “it.” In particular, if there is no Hamlet to talk about, we surely cannot truthfully say that “he” does not exist. Hence, the truth of true negative (...) class='Hi'>existentials—and there are many—seems to preclude their truth and falsity. Call this “the negative existential problem.”. (shrink)

In this paper, I try to show that Kripke’s proposed solution to the problem of negative existentials fails. I try to show that Kripke’s proposal fails because it entails that anybody who has good reasons to believe that there are no propositions has also good reasons to believe that he or she does not exist. However, there were philosophers who had good reasons to believe that there are no propositions even though they didn’t have good reasons to believe that (...) they do not exist. I conclude that Kripke’s proposed solution to the problem of negative existentials fails. (shrink)

IN THE beginning Parmenides sought to deny the void. But he found himself trapped by his language and his thought into admitting what he sought to deny. Wisely, he counseled others to avoid the whole region in which the problem arises, lest they too be unwarily ensnared. Plato, being less easily intimidated and grasping for the first time the urgency of the paradox, unearthed each snare in turn until he felt he had found a safe path through the forbidden terrain (...) in a new conception of being and the derivation of its linguistic consequences in the Sophist. Aristotle evidently took Parmenides’ advice; and save for a few groping scholastics, perhaps Leibniz, Brentano, and Meinong, and Frege only in passing, no one else attempted the crossing before Russell made his spectacular dash through the posted ground from the completely new direction of linguistic reference. Again the problem lay dormant for half a century until Strawson constructed a new low road through ordinary language and Quine improved Russell’s high algebraic pass. Refinements of these routes have been forthcoming, especially from Searle and Kripke, until today it might appear that there are two super highways through Parmenides’ forbidden country of nonbeing. In this essay I will first argue that these new linguistic highways are no more than flimsy camouflage hiding but not resolving the old paradoxes. I will then show how Plato’s ontological way out, though more difficult, is the straight and narrow path. (shrink)

In a 2019 paper, Hausmann raised a new and interesting problem for Kripke’s account of negative existentials. He argued that Kripke’s account leads to the absurd consequence that anybody who has good reasons to believe that there are no propositions also has good reasons to believe that he or she does not exist. In this paper I propose a modified Kripkean theory, which is invulnerable to a Hausmann-like argument. As will be seen, the modified theory can be squarely justified (...) in light of the key observations behind Kripke’s original proposal. (shrink)

In this paper I am concerned with an analysis of negative existential sentences that contain proper names only by using negative or neutral free logic. I will compare different versions of neutral free logic with the standard system of negative free logic (Burge, Sainsbury) and aim to defend my version of neutral free logic that I have labeled non-standard neutral free logic.

Thanks to the Inlaks Foundation in India, I was able to do my doctoral research on Our Talk About Nonexistents at Oxford in the early eighties. The two greatest philosophers of that heaven of analytical philosophy - Peter Strawson and Michael Dummett - supervised my work, reading and criticising all the fledgling philosophy that I wrote during those three years. At Sir Peter's request, Gareth Evans, shortly before his death, lent me an unpublished transcript of Kripke's John Locke Lectures. Work (...) on the Appendix about Indian Philosophy was supervised by the late Professor Bimal Krishna Matilal with whom informal but intense philosophical conversations used to spill over into dinner at his place almost every other day. It was Professor Matilal who sent me, over a summer, to study a tough Navya-Nyaya text under his own Nyaya teacher Pandit Visvabandhu Tarkatirtha at Calcutta. All four of these teachers were as kind to me as my life-long mentor in philosophy Professor Pranab Kumar Sen, whose clarity and depth remain the unreachable regu lative ideal of my intellect. When I came back to India, my life became blissfully free of the agonising anxiety to publish, until, after a conference at Jadavpur University where I gave an impromptu paper, ironically enough, on Non-doings, I met Derek Parfit. He had a six-hour conversation with me, explicitly planning my life. Five years had already elapsed since I had finished my D. Phil, but Derek read my thesis and liked it. (shrink)

We have become estranged from the cosmic movements, according to Bataille. We are confined by the error linked to the representation of ‘the stationary earth’. We have negated the immersive immanence of the whole and made nature into a fixed world of tools and things. How then do we recognise ourselves as part of the ‘rapture of the heavens’? Bataille urges us to consider life as a solar phenomenon, the free play of solar energy on the earth. This paper argues (...) how Bataille’s cosmic vision anticipates both planetary and ecological thinking. This entails a base materialism of difference based on a radical Nietzschean and Heraclitean theory of becoming and flux. This thought is developed along Bataillean concepts such as the movement of the whole, the labyrinthine, and compound beings, ipseity, as well as the concept of a communifying movement. This materialism paired with Vladimir Vernadsky’s biosphere lays the foundation for the laws of the general economy, which also constitutes an economy inclusive of a general ecology: a tragic vision of Gaia and Dionysos. Finally, poetry is considered, as a way we might reconnect with the universe and stimulate ecological imagination. (shrink)

This article discusses how existential phenomenology may serve as a frame in a mixed‐methods study of changes in weight and body composition among women in adjuvant treatment for breast cancer. In accordance with ontologically and epistemologically fundamental assumptions in nursing, we link mixed‐methods and existential phenomenology from the perspective of the French philosopher Maurice Merleau‐Ponty and his notion of a unified body subject. Letting this perspective permeate our philosophy, methodology and issues at the method level in mixed‐method research undermines the (...) distinction between first‐ and third‐person perspective when applying and integrating different data sources in a mixed‐methods study. Applying Merleau‐Ponty's third way, the women's bodily experiences appear as gestalt; a ‘figure’ against a ground of existential threats that are grasped through insight from data integrating in joint displays, which revealed the women's experiences on a deep existential level. Existential phenomenology as a frame in mixed‐method studies can speak not only to nurses but also to a multidisciplinary audience in a shared attempt to deepen the understanding of a patient's healthcare problem.

The provability problem in intuitionistic propositional second-order logic with existential quantifier and implication (∃,→) is proved to be undecidable in presence of free type variables (constants). This contrasts with the result that inutitionistic propositional second-order logic with existential quantifier, conjunction and negation is decidable.

The purpose of the book is to clarify the notion of existential dependence and cognate notions, such as supervenience and the notion of an internal relation. I defend the view that such notions are best understood in terms of the concept of metaphysical grounding, i.e. the concept of one fact obtaining in virtue of other facts, where ‘in virtue of’ has a distinctively metaphysical meaning.

This paper examines and analyzes five definitions of ‘existential risk.’ It tentatively adopts a pluralistic approach according to which the definition that scholars employ should depend upon the particular context of use. More specifically, the notion that existential risks are ‘risks of human extinction or civilizational collapse’ is best when communicating with the public, whereas equating existential risks with a ‘significant loss of expected value’ may be the most effective definition for establishing existential risk studies as a legitimate field of (...) scientific and philosophical inquiry. In making these arguments, the present paper hopes to provide a modicum of clarity to foundational issues relating to the central concept of arguably the most important discussion of our times.

By putting existential phenomenology into conversation with virtue ethics, this book offers a new interpretation of human flourishing. It rejects characterizations of flourishing as either a private subjective state or an objective worldly status, arguing that flourishing is rather a successfully negotiated self-world fit – a condition involving both the essential dependence of the self upon the world and others, and the lived normative responsiveness of the agent striving to be in the world well. A central argument of the book (...) is that there is an irreducible normative plurality arising from the different practical perspectives we can adopt – the first, second, and third-person stances – all of which make different kinds of normative claim that we understand ourselves as having reason to meet. Flourishing is human excellence within each of these normative domains (self-fulfillment, moral responsibility, and responsiveness to intersubjective standards) achieved in such a way that success in one domain does not compromise success in another. Existential Flourishing provides a correspondingly transformed interpretation of the virtues as solutions to various existential problems we face in responding to these normative domains. The book also addresses traditional problems in virtue ethics and analyzes the structure of four virtues in detail: justice, patience, modesty, and courage. (shrink)

The following pages attempt to develop the main outlines of an existential phenomenology of law within the context of Maurice Merleau-Ponty's phe nomenology of the social world. In so doing, the essay addresses the rather narrow scholarly question, If Merleau-Ponty had written a phenomenology of law, what would it have looked like? But this scholarly enterprise, although impeccable in itself, is also transcended by a more complicated concern for a very different sort of question. Namely, if Merleau-Ponty's phenomenological descriptions of (...) the social world are correct-as I believe they largely are-then what are the philosophical consequences for an adequate understanding of law? Such a project may well occasion a certain surprise amongst observers of the contemporary philosophical landscape, at least in what concerns the terrain of continental thought, and for two different reasons. The first is that, although interest in Merleau-Ponty's work remains strong in the· United States and Can ada, his philosophical standing in his own country has been largely eclipsed! by that of, first, his friend/estranged acquaintance, Jean-Paul Sartre; by various Marxist philosophies and critical social theories; and finally by those doing her meneutics of language. In my view, current neglect of Merleau-Ponty's thought in France is most regrettable. (shrink)

The study of existentially closed closure algebras begins with Lipparini’s 1982 paper. After presenting new nonelementary axioms for algebraically closed and existentially closed closure algebras and showing that these nonelementary classes are different, this paper shows that the classes of finitely generic and infinitely generic closure algebras are closed under finite products and bounded Boolean powers, extends part of Hausdorff’s theory of reducible sets to existentially closed closure algebras, and shows that finitely generic and infinitely generic closure algebras are elementarily (...) inequivalent. Special properties of algebraically closed, existentially closed, finitely generic, and infinitely generic closure algebras are established along the way. (shrink)

We prove that the standard cut is definable in each existentially closed model ofIΔ0+ exp by a (parameter free) П1–formula. This definition is optimal with respect to quantifier complexity and allows us to improve some previously known results on existentially closed models of fragments of arithmetic.

The existential approach described by Mark Nesti offers a radical alternative to the cognitive-behavioral model which informs most contemporary applied sports psychology. Whereas standard psychological models of athlete behavior would advocate appropriate "mental skills" training such as visualizing the perfect race to help an athlete overcome performance problems, the existential approach will refer to an athletes unique emotional world to find deeper causes of their limitation. These causes may be only very indirectly linked to the athletes sporting life. Existential sports (...) psychology has gone out of phenomenological theory and existential philosophy. Mark Nesti's text is the first book to present an overview of this exciting approach. It contains case studies and a framework for psychologists to apply this approach to their work. (shrink)

In ancient China, a revered Taoist sage named Zhuangzi told many parables. In Existential Psychology and the Way of the Tao, a selection of these parables will be featured. Following each parable, an eminent existential psychologist will share a personal and scholarly reflection on the meaning and relevance of the parable for psychotherapy and contemporary life. The major tenets of Zhuangzi's philosophy are featured. Taoist concepts of emptiness, stillness, Wu Wei (i.e. intentional non-intentionality), epistemology, dreams and the nature of reality, (...) character building in the midst of pain, meaning and the centrality of relationships, authenticity, self-care, the freedom that can come from one's willingness to confront death, spiritual freedom, and gradations of therapeutic care are topics highlighted in this book.

An existential-dialectical-phenomenological approach is applied to the understanding of the universal tensions between multicultural and transcultural value-laden modalities of existence. Differences in cultural comportments are described as variations in local human ways in dealing with universal and bipolar existential modalities, values, or needs, such as freedom versus limitation, independence versus dependence, and connectedness versus separateness. Cultures are described as being organized around and as providing their members with ways of dealing with these value-laden dialectical dilemmas. Cultures are further depicted as (...) legitimating one dialectical pole to the detriment of the other dialectical pole. Some cultures, for example, legitimate the dialectical poles of freedom, independence, and separateness, while deemphasizing or denying the dialectical poles of limitation, dependence, and connectedness. Other cultures legitimate the opposite. These one-sided value orientations of cultures are referred to as cultural tilts. The implications for the practice of multicultural counseling and phenomenologically-based qualitative research are delineated. (shrink)

Background: According to ethical guidelines, healthcare professionals should be able to provide care that allows for the patients’ values, customs and beliefs, and the existential issues that are communicated through them. One widely discussed issue is existential loneliness. However, much of the debate dealing with existential loneliness concludes that both the phenomenon and the concept are quite vague. Aim: To clarify what constitutes existential loneliness, and to describe its lived experiences. A further aim was to provide a definition of existential (...) loneliness that can function as a tool for identifying the phenomenon and for differentiating it from other kinds of loneliness. Method: A literature review including theoretical and empirical studies. Different search strategies were used to gather the articles included in the study. The analysis of the empirical studies had an interpretative approach. The articles were also analysed with the aim of providing a definition of existential loneliness. This was done by means of criteria such as language, uniqueness, theory and usefulness. This study is not empirical and does therefore not require an ethics review. Results: The analysis resulted in two main characteristics. The first one was perceiving oneself as inherently separated (disconnected) from others and from the universe. The second one brings out emotional aspects of EL, such as isolation, alienation, emptiness and a feeling of being abandoned. The empirical findings were divided into two categories: experiences of EL and circumstances in which EL arises. A definition of EL is also suggested, based on the two main characteristics identified. Conclusion: In order to meet patients’ needs, it is an ethical duty for healthcare staff to be able to recognise experiences of EL, that is, to communicate with the patients about these experiences in an appropriate manner. This in turn demands knowledge about existential issues and skills to deal with them. (shrink)

While there is a great deal to agree with in the essay Expanded Terminal Sedation in End-of-Life Care there is, we think, a need to more fully appreciate the humanistic side of both palliative and end-of-life care.1 Not only does the underlying philosophy of palliative care arguably differ from that which guides curative medicine,2 dying patients are in a uniquely vulnerable position given our cultural disinclination towards open discussions of death and dying. In this brief response, we critically engage Gilbertson (...) et al ’s essay and seek to contextualise the perspective they put forward. According to Cassell, we should distinguish between pain and suffering.3 The former often gives rise to the latter, but suffering has other causes. This includes existential distress, indicating that, unlike pain, suffering is not simply physiological phenomena. Suffering involves the disintegration of the person, meaning that it can impact patient autonomy. Certainly, that a patient is suffering does not equate to a lack autonomy. Nevertheless, we should take care when making decisions in circumstance where the integrity of our embodied personhood is under threat, something that is clearly the case for those who are dying, particularly those who have refractory symptoms while doing so. Generally speaking, refractory symptoms are those which are intractable. They persist despite attempts at palliation. While this implies that such symptoms—and the suffering they cause—cannot be reversed this is not necessarily the case. Not only can the symptoms experienced by dying patients change …. (shrink)

In Existential Psychoanalysis, Sartre criticizes modern psychology in general, and Freud's determinism in particular. His often brilliant analysis of these areas and his proposals for their correction indicate in what direction an existential psychoanalysis might be developed. Sartre does all this on the basis of his existential understanding of man, and his unshakeable conviction that the human being simply cannot be understood at all if we see in him only what our study of subhuman forms of life permits us to (...) see, or if we reduce him to naturalistic or mechanical determinism, or in any other way take away from the man we try to study his ultimate freedom and individual responsibility. An incisive introduction by noted existential psychologist Rollo May guides readers through these challenging yet enlightening passages. (shrink)

Existential grounding is the thesis that all existential generalizations are grounded in their particular instances. This paper argues that existential grounding is false. This is because it is inconsistent with two plausible claims about existence: the claim that singular existence facts are generalizations and the claim that no object can be involved in a fact that grounds that same object's existence. Not only are these claims intuitively plausible, but there are also strong arguments in favour of each of them.

This paper offers a new semantic theory of existentials (sentences of the form There be NP pivot XP coda ) in which pivots are (second order) predicates and codas are modifiers. The theory retains the analysis of pivots as denoting generalized quantifiers (Barwise and Cooper 1981; Keenan 1987), but departs from previous analyses in analyzing codas as contextual modifiers on a par with temporal/locative frame adverbials. Existing analyses universally assume that pivots are arguments of some predicate, and that codas (...) are main or secondary predicates. It is shown that these analyses cannot account for the behavior of codas with quantifiers and for the interaction of multiple codas, both of which receive a simple treatment on the proposed theory. The assimilation of codas to frame adverbials explains several semantic properties which have not been analyzed in the semantic literature, and that distinguish existentials from their copular counterparts. Furthermore, it highlights important properties of the semantics of modification and its relation to predication. (shrink)

To all appearances, the basic building blocks of reality tend to keep existing unless something intervenes to destroy them. In other words, basic things seem to have existential inertia. But why might this be? This paper considers a number of arguments for and against existential inertia. It discusses arguments inspired by Aquinas, Descartes, and Spinoza, as well as considerations deriving from Occam’s Razor, entropy, and certain views about the nature of time and change.

Peirce’s True Gorgias is a brief dialogue from his essay “Grounds of Validity of the Laws of Logic”, published in 1869. The True Gorgias exposes the fallacy of existential import. It has received no sustained attention in the secondary literature, perhaps because the fallacy is now familiar. Peirce’s assessment of the fallacy involved in the reasoning, however, changes between 1865 and 1869, and he only arrives at the contemporary account of existential import in 1880. Moreover, a careful examination of the (...) context in which the True Gorgias appears reveals it provides an argument in support of Peirce’s early Aristotelian realism about universals in contradistinction to non-Aristotelian varieties of realism advocated by W.T. Harris, editor of the journal in which the True Gorgias was published. (shrink)

Charles Peirce developed Existential Graphs as a diagrammatic syntax for representing and reasoning about propositions, with three parts: Alpha for propositional logic, Beta for first-order predicate logic, and Gamma for aspects of modal logic, second-order logic, and metalanguage. He made several adjustments between 1909 and 1911 that merit further consideration: using heavy lines to denote possible states of things in which attached propositions would be true, drawing a red line just inside the edge of a page and writing postulates in (...) the resulting margin, shading oddly enclosed areas instead of drawing thin lines as their boundaries, and using multiple sheets of paper to represent different subjects within the overall universe of discourse. These modifications can be combined to constitute a plausible candidate for Delta, a fourth part that Peirce intended to add but never spelled out. It implements modern formal systems of modal propositional logic in accordance with a version of possible worlds semantics in which the laws for the actual state of things are facts in every possible state of things.

This collection of ten original essays was first published in 1977. It engages the 'crisis in sociology' at the most fundamental level of thought and experience. Existential sociology is defined as the study and understanding of all forms of human existence. Without seeking to erect a pristine philosophical sanctuary of its own, Existential Sociology examines and criticizes the underlying philosophical assumptions of previous theories of social science, while elaborating its own approach to human understanding. The contributors are concerned with constructing (...) practical as well as theoretical truths about social life - how we feel, think and act. In contrast to most other sociologies, the emphasis is on the independence and dominance of human feelings over the evaluative and cognitive features of social actions. Students and teachers of sociology and people in related fields interested in the connection between social science and their own subjects will find Existential Sociology useful and absorbing.

A lucid introduction to the "existential phenomenology" of Martin Heidegger, particularly as developed in his major work, Being and Time, this work focuses on how Heidegger's ideas bear on the central problem in epistemology--that of how we can have objective knowledge. The author constructs fresh arguments clarifying Heidegger's contribution to the theory of knowledge, and shows why Heidegger deemed misguided the search for knowledge of the way things are in themselves.

The standard argument to the conclusion that artificial intelligence (AI) constitutes an existential risk for the human species uses two premises: (1) AI may reach superintelligent levels, at which point we humans lose control (the ‘singularity claim’); (2) Any level of intelligence can go along with any goal (the ‘orthogonality thesis’). We find that the singularity claim requires a notion of ‘general intelligence’, while the orthogonality thesis requires a notion of ‘instrumental intelligence’. If this interpretation is correct, they cannot be (...) joined as premises and the argument for the existential risk of AI turns out invalid. If the interpretation is incorrect and both premises use the same notion of intelligence, then at least one of the premises is false and the orthogonality thesis remains itself orthogonal to the argument to existential risk from AI. In either case, the standard argument for existential risk from AI is not sound.—Having said that, there remains a risk of instrumental AI to cause very significant damage if designed or used badly, though this is not due to superintelligence or a singularity.

This article focuses on existential feelings. To begin with, it depicts how they differ from other affective phenomena and what type of intentionality they manifest. Furthermore, a detailed analysis shows that existential feelings can be subdivided, first, into elementary and nonelementary varieties, and second, into three foci of primary relatedness: oneself, the social environment, and the world as such. Eventually, five strategies of emotion regulation are examined with respect to their applicability to existential feelings. In the case of harmful existential (...) feelings, it turns out that none seems fitting except one, attentional deployment. (shrink)

Patients with a life-threatening illness can be confronted with various types of loneliness, one of which is existential loneliness (EL). Since the experience of EL is extremely disruptive, the issue of EL is relevant for the practice of end-of-life care. Still, the literature on EL has generated little discussion and empirical substantiation and has never been systematically reviewed. In order to systematically review the literature, we (1) identified the existential loneliness literature; (2) established an organising framework for the review; (3) (...) conducted a conceptual analysis of existential loneliness; and (4) discussed its relevance for end-of-life care. We found that the EL concept is profoundly unclear. Distinguishing between three dimensions of EL—as a condition, as an experience, and as a process of inner growth—leads to some conceptual clarification. Analysis of these dimensions on the basis of their respective key notions—everpresent, feeling, defence; death, awareness, difficult communication; and inner growth, giving meaning, authenticity—further clarifies the concept. Although none of the key notions are unambiguous, they may function as a starting point for the development of care strategies on EL at the end of life. (shrink)

A small but growing number of studies have aimed to understand, assess and reduce existential risks, or risks that threaten the continued existence of mankind. However, most attention has been focused on known and tangible risks. This paper proposes a heuristic for reducing the risk of black swan extinction events. These events are, as the name suggests, stochastic and unforeseen when they happen. Decision theory based on a fixed model of possible outcomes cannot properly deal with this kind of event. (...) Neither can probabilistic risk analysis. This paper will argue that the approach that is referred to as engineering safety could be applied to reducing the risk from black swan extinction events. It will also propose a conceptual sketch of how such a strategy may be implemented: isolated, self-sufficient, and continuously manned underground refuges. Some characteristics of such refuges are also described, in particular the psychosocial aspects. Furthermore, it is argued that this implementation of the engineering safety strategy safety barriers would be effective and plausible and could reduce the risk of an extinction event in a wide range of possible scenarios. Considering the staggering opportunity cost of an existential catastrophe, such strategies ought to be explored more vigorously. (shrink)

The notion of existential catastrophe is increasingly appealed to in discussion of risk management around emerging technologies, but it is not completely clear what this notion amounts to. Here, I provide an opinionated survey of the space of plausibly useful definitions of existential catastrophe. Inter alia, I discuss: whether to define existential catastrophe in ex post or ex ante terms, whether an ex ante definition should be in terms of loss of expected value or loss of potential, and what kind (...) of probabilities should be involved in any appeal to expected value.
