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.

The greatest existential threats to humanity stem from increasingly powerful advanced technologies. Yet the “risk potential” of such tools can only be realized when coupled with a suitable agent who; through error or terror; could use the tool to bring about an existential catastrophe. While the existential risk literature has provided many accounts of how advanced technologies might be misused and abused to cause unprecedented harm; no scholar has yet explored the other half of the agent-tool coupling; namely the agent. (...) This paper aims to correct this failure by offering a comprehensive overview of what we could call “agential riskology.” Only by studying the unique properties of different agential risk types can one acquire an accurate picture of the existential danger before us.

This chapter argues that dual-use emerging technologies are distributing unprecedented offensive capabilities to nonstate actors. To counteract this trend, some scholars have proposed that states become a little “less liberal” by implementing large-scale surveillance policies to monitor the actions of citizens. This is problematic, though, because the distribution of offensive capabilities is also undermining states’ capacity to enforce the rule of law. I will suggest that the only plausible escape from this conundrum, at least from our present vantage point, is (...) the creation of a “supersingleton” run by a friendly superintelligence, founded upon a “post-singularity social contract.” In making this argument, the present chapter offers a novel reason for prioritizing the “control problem,” i.e., the problem of ensuring that a greaterthan-human-level AI will positively enhance human well-being.

Lethal Autonomous Weapons (LAWs) are robotic weapons systems, primarily of value to the military, that could engage in offensive or defensive actions without human intervention. This paper assesses and engages the current arguments for and against the use of LAWs through the lens of achieving more ethical warfare. Specific interest is given particularly to ethical LAWs, which are artificially intelligent weapons systems that make decisions within the bounds of their ethics-based code. To ensure that a wide, but not exhaustive, survey (...) of the implications of employing such ethical devices to replace humans in warfare is taken into account, this paper will engage on matters related to current scholarship on the rejection or acceptance of LAWs—including contemporary technological shortcomings of LAWs to differentiate between targets and the behavioral and psychological volatility of humans—and current and proposed regulatory infrastructures for developing and using such devices. After careful consideration of these factors, this paper will conclude that only ethical LAWs should be used to replace human involvement in war, and, by extension of their consistent abilities, should remove humans from war until a more formidable discovery is made in conducting ethical warfare.

In Unfit for the Future, Ingmar Persson and Julian Savulescu argue that our collective existetial predicment is unprecedentedly dangerous due to climate change and terrorism. Given these global risks to human prosperity and survival, Persson and Savulescu argue that we should explore the radical possibility of moral bioenhancement in addition to cognitive enhancement. In this article, I argue that moral bioenhancements could nontrivially exacerbate the threat posed by certain kinds of malicious agents, while reducing the threat of other kinds. This (...) introduces a previously undiscussed complication to Persson and Savulescu's proposal. In the final section, I present a novel argument for why moral bioenhancement should either be compulsory or not be made available to the public at all. (shrink)

Purpose This paper aims to formalize long-term trajectories of human civilization as a scientific and ethical field of study. The long-term trajectory of human civilization can be defined as the path that human civilization takes during the entire future time period in which human civilization could continue to exist. -/- Design/methodology/approach This paper focuses on four types of trajectories: status quo trajectories, in which human civilization persists in a state broadly similar to its current state into the distant future; catastrophe (...) trajectories, in which one or more events cause significant harm to human civilization; technological transformation trajectories, in which radical technological breakthroughs put human civilization on a fundamentally different course; and astronomical trajectories, in which human civilization expands beyond its home planet and into the accessible portions of the cosmos. -/- Findings Status quo trajectories appear unlikely to persist into the distant future, especially in light of long-term astronomical processes. Several catastrophe, technological transformation and astronomical trajectories appear possible. -/- Originality/value Some current actions may be able to affect the long-term trajectory. Whether these actions should be pursued depends on a mix of empirical and ethical factors. For some ethical frameworks, these actions may be especially important to pursue. (shrink)

A new book by Phil Torres, Morality, Foresight, and Human Flourishing: An Introduction to Existential Risks, is reviewed. Morality, Foresight and Human Flourishing is a primer intended to introduce students and interested scholars to the concepts and literature on existential risk. The book’s core methodology is to outline the various existential risks currently discussed in different disciplines and provides novel strategies for risk mitigation. The book is stylistically engaging, lucid and academically current, providing both novice readers and seasoned (...) scholars with an easy-to-read introduction to risk studies. The book is by far the most engaging and comprehensive volume on risk studies aimed at captivating new scholars to the field. (shrink)

Recent discussion of the alleged adverse consequences of space colonization by Phil Torres in this journal is critically assessed. While the concern for suffering risks should be part of any strategic discussion of the cosmic future of humanity, the Hobbesian picture painted by Torres is largely flawed and unpersuasive. Instead, there is a very real risk that the skeptical arguments will be taken too seriously and future human flourishing in space delayed or prevented.

De se attitudes seem to play a special role in action and cognition. This raises a challenge to the traditional way in which mental attitudes have been understood. In this chapter, we review the case for thinking that de se attitudes require special theoretical treatment and discuss various ways in which the traditional theory can be modified to accommodate de se attitudes.

Philosophical Dilemmas: A Pro and Con Introduction to the Major Questions, 2/e, is a lucidly written and comprehensive introduction to philosophy featuring sixty brief essays arranged in pairs. Each pair answers one of the standard philosophical questions, such as "Does God exist?" or "Is morality relative?," with affirmative and negative responses. Each essay takes a definite stand and promotes it vigorously, creating a sharp contrast between the two positions and giving each abstract theory a more personal and believable "voice." While (...) the essays often employ traditional arguments of great philosophers, they present the ideas in contemporary language with vivid examples. The accessible style and conflicting answers encourage students to examine the different positions and to think carefully about which essay makes the stronger case. While other textbooks present a series of excerpts and theories without attempting to coordinate them into a larger picture, Philosophical Dilemmas teaches students about the process of thinking philosophically and encourages them to construct their own coherent worldviews. This second edition features new sections on race, gender, euthanasia, and Buddhist philosophy, showing students how philosophy applies to issues that they may encounter in their own lives. The text incorporates numerous pedagogical features including a list of historical parallels, key terms, chapter summaries, a glossary, an introduction to each issue, and critical questions following each essay. Brief sections throughout the book describe numerous critical thinking techniques demonstrated by the essays. An annotated bibliography of historical examples for each issue and useful lists of contemporary sources further enhance the text's utility. An Instructor's Manual, including chapter summaries, writing assignments, and test questions, is available. (shrink)

The Vocabulary of Critical Thinkingtakes an innovative, practical, and accessible approach to teaching critical thinking and reasoning skills. With the underlying notion that a good way to practice fundamental reasoning skills is to learn to name them, the text explores one hundred and eight words that are important to know and employ within any discipline. These words are about comparing, generalizing, explaining, inferring, judging sources, evaluating, referring, assuming and creating - actions used to assess relationships and arguments - and the (...) words are grouped according to these and other concepts essential to critical thinking. Featuring five or more words and an introduction on how they are related, each chapter is organized into three parts. Part I includes definitions of the words, brief examples of their use, and matching exercises. To further contextualize the words, Part II, Understanding the Meaning, provides numerous real-world examples, with commentary, of the words in use. Finally, Part III, providing practice of the associated critical thinking skills. Questions also appear throughout the chapters to encourage reflection and to highlight important points. Thirty-five photographs and illustrations additionally enrich the text. The book is an ideal text for critical thinking and reasoning courses as well as a variety of courses that prepare students to succeed. (shrink)

In a recent paper (1994) Wesley Salmon has replied to criticisms (e.g., Dowe 1992c, Kitcher 1989) of his (1984) theory of causality, and has offered a revised theory which, he argues, is not open to those criticisms. The key change concerns the characterization of causal processes, where Salmon has traded "the capacity for mark transmission" for "the transmission of an invariant quantity." Salmon argues against the view presented in Dowe (1992c), namely that the concept of "possession of a conserved quantity" (...) is sufficient to account for the difference between causal and pseudo processes. Here that view is defended, and important questions are raised about the notion of transmission and about gerrymandered aggregates. (shrink)

This book, published in 2000, is a clear account of causation based firmly in contemporary science. Dowe discusses in a systematic way, a positive account of causation: the conserved quantities account of causal processes which he has been developing over the last ten years. The book describes causal processes and interactions in terms of conserved quantities: a causal process is the worldline of an object which possesses a conserved quantity, and a causal interaction involves the exchange of conserved quantities. Further, (...) things that are properly called cause and effect are appropriately connected by a set of causal processes and interactions. The distinction between cause and effect is explained in terms of a version of the fork theory: the direction of a certain kind of ordered pattern of events in the world. This particular version has the virtue that it allows for the possibility of backwards causation, and therefore time travel. (shrink)

Although arguments for and against competing theories of vagueness often appeal to claims about the use of vague predicates by ordinary speakers, such claims are rarely tested. An exception is Bonini et al. (1999), who report empirical results on the use of vague predicates by Italian speakers, and take the results to count in favor of epistemicism. Yet several methodological difficulties mar their experiments; we outline these problems and devise revised experiments that do not show the same results. We then (...) describe three additional empirical studies that investigate further claims in the literature on vagueness: the hypothesis that speakers confuse ‘P’ with ‘definitely P’, the relative persuasiveness of different formulations of the inductive premise of the Sorites, and the interaction of vague predicates with three different forms of negation.

In this article we argue that nanotechnology represents an extraordinary opportunity to build in a robust role for the social sciences in a technology that remains at an early, and hence undetermined, stage of development. We examine policy dynamics in both the United States and United Kingdom aimed at both opening up, and closing down, the role of the social sciences in nanotechnologies. We then set out a prospective agenda for the social sciences and its potential in the future shaping (...) of nanotechnology research and innovation processes. The emergent, undetermined nature of nanotechnologies calls for an open, experimental, and interdisciplinary model of social science research. (shrink)

Aristotle holds that individual substances are ontologically independent from nonsubstances and universal substances but that non-substances and universal substances are ontologically dependent on substances. There is then an asymmetry between individual substances and other kinds of beings with respect to ontological dependence. Under what could plausibly be called the standard interpretation, the ontological independence ascribed to individual substances and denied of non-substances and universal substances is a capacity for independent existence. There is, however, a tension between this interpretation and the (...) asymmetry between individual substances and the other kinds of entities with respect to ontological independence. I will propose an alternative interpretation: to weaken the relevant notion of ontological independence from a capacity for independent existence to the independent possession of a certain ontological status. (shrink)

Causal pluralists hold that that there is not just one determinate kind of causation. Some causal pluralists hold that ‘cause’ is ambiguous among these different kinds. For example, Hall (2004) argues that ‘cause’ is ambiguous between two causal relations, which he labels dependence and production. The view that ‘cause’ is ambiguous, however, wrongly predicts zeugmatic conjunction reduction, and wrongly predicts the behaviour of ellipsis in causal discourse. So ‘cause’ is not ambiguous. If we are to disentangle causal pluralism from the (...) ambiguity claim, we need to consider what other linguistic approaches are available to the causal pluralist. I consider and reject proposals that ‘cause’ is a general term, that the term is an indexical, and that the term conveys different kinds of causation through implicature or presupposition. Finally, I argue that causal pluralism is better handled by treating ‘cause’ as a univocal term within a dynamic interpretation framework. (shrink)

Call ‘a substance’ a person who is at home in a relatively stable and unified sense-making framework: a social structure that to some degree specifies which categories are important for interpreting reality, which goals are worth pursing, which character traits are admirable, etc. Call ‘an accident’ a person who is not at home in one such framework. It is tempting to think that being a substance is preferable, but I present some considerations for thinking otherwise. Mexican philosophers Emilio Uranga and (...) Jorge Portilla, I argue, present notions of accidentality as decolonial tools. Uranga’s account enables Mexicans to have positive valuation of their being independently of the approving gaze of the colonizers and their standards of value. Portilla’s thought distinguishes between pernicious accidentality resulting from the disintegration of sense-making frameworks and authentic accidentality as a condition for freedom, self-creation, and ultimately for individual and communal liberation.

This paper examines Wesley Salmon's "process" theory of causality, arguing in particular that there are four areas of inadequacy. These are that the theory is circular, that it is too vague at a crucial point, that statistical forks do not serve their intended purpose, and that Salmon has not adequately demonstrated that the theory avoids Hume's strictures about "hidden powers". A new theory is suggested, based on "conserved quantities", which fulfills Salmon's broad objectives, and which avoids the problems discussed.

Discussion of the Aristotelian syllogistic over the last sixty years has arguably centered on the question whether syllogisms are inferences or implications. But the significance of this debate at times has been taken to concern whether the syllogistic is a logic or a theory, and how it ought to be represented by modern systems. Largely missing from this discussion has been a study of the few passages in the Prior Analytics where Aristotle provides explicit guidance on how to individuate syllogisms. (...) I argue that syllogisms are individuated by unordered premise pairs and so may be fruitfully thought of as multi-succedent sequents. I conclude by drawing a few consequences for the representation of the syllogistic. (shrink)

Is there grounding in ancient philosophy? To ask a related but different question: is grounding a useful tool for the scholar of ancient philosophy? These questions are difficult, and my goal in this paper is not so much to give definitive answers as to clarify the questions. I hope to direct the student of contemporary metaphysics towards passages where it may be fruitful to look for historical precedent. But I also hope to offer the student of ancient philosophy some guidance (...) on when drawing on the contemporary discussion of grounding may be beneficial. (shrink)

The relation of ontological dependence or grounding, expressed by the terminology of separation and priority in substance, plays a central role in Aristotle’s Categories, Metaphysics, De Anima and elsewhere. The article discusses three current interpretations of this terminology. These are drawn along the lines of, respectively, modal-existential ontological dependence, essential ontological dependence, and grounding or metaphysical explanation. I provide an opinionated introduction to the topic, raising the main interpretative questions, laying out a few of the exegetical and philosophical options that (...) influence one’s reading, and locating questions of Aristotle scholarship within the discussion of ontological dependence and grounding in contemporary metaphysics.

There is, no doubt, a temptation to treat preventions, such as ‘the father’s grabbing the child prevented the accident’, and cases of ‘causation’ by omission, such as ‘the father’s inattention was the cause of the child’s accident’, as cases of genuine causation. I think they are not, and in this paper I defend a theory of what they are. More specifically, the counterfactual theory defended here is that a claim about prevention or ‘causation’ by omission should be understood not as (...) being directly about actual genuine causation but primarily as a counterfactual claim about genuine causation.1 The relation between actual causation and the mere possibility of causation allows my theory to explain both the difference and the similarity between the two notions (causation and prevention/omission). Further, the difference explains certain intuitions we have and the similarity justifies and explains the fact that for practical purposes we usually treat preventions and omissions as if they were genuine causation. Finally, the fact that this counterfactual theory of prevention and omission takes causation as primitive suggests that it is consistent with any theory of causation. This allows us to construct two arguments against what I will call genuinism, the view that cases of prevention and ‘causation’ by omission really are cases of genuine causation. In section II I show that genuinism does not account for the so-called intuition of difference. In section III I outline a number of problems that various theories of causation have with preventions and ‘causation’ by omission. These problems are ipso facto problems for genuinism, whereas I show in section V how the counterfactual theory solves those problems. Further, I answer a genuinist argument based on another type of intuition—the genuinist intuition—by showing why we have that intuition and how it should be handled (section VI). (shrink)

Both literalism, the view that mathematical objects simply exist in the empirical world, and fictionalism, the view that mathematical objects do not exist but are rather harmless fictions, have been both ascribed to Aristotle. The ascription of literalism to Aristotle, however, commits Aristotle to the unattractive view that mathematics studies but a small fragment of the physical world; and there is evidence that Aristotle would deny the literalist position that mathematical objects are perceivable. The ascription of fictionalism also faces a (...) difficult challenge: there is evidence that Aristotle would deny the fictionalist position that mathematics is false. I argue that, in Aristotle's view, the fiction of mathematics is not to treat what does not exist as if existing but to treat mathematical objects with an ontological status they lack. This form of fictionalism is consistent with holding that mathematics is true. (shrink)

Individual substances are the ground of Aristotle’s ontology. Taking a liberal approach to existence, Aristotle accepts among existents entities in such categories other than substance as quality, quantity and relation; and, within each category, individuals and universals. As I will argue, individual substances are ontologically independent from all these other entities, while all other entities are ontologically dependent on individual substances. The association of substance with independence has a long history and several contemporary metaphysicians have pursued the connection. In this (...) chapter, I will discuss the intersection of these notions of substance and ontological dependence in Aristotle. I will canvass a few contemporary formulations of ontological dependence and discuss some of the interpretative difficulties in ascribing any of these formulations to Aristotle’s characterization of individual substances as ontologically independent. My aim is not to resolve fully these difficulties but to locate the topics of substance and independence relative to certain other controversies in Aristotle studies. However, I will sketch a position. In particular, elsewhere I have speculated that Aristotle is both a primitivist and a pluralist with respect to ontological dependence, and I will develop this line of interpretation a bit further later in the chapter.

Gordon Baker in his last decade published a series of papers (now collected inBaker 2004), which are revolutionary in their proposals for understanding of later Wittgenstein. Taking our lead from the first of those papers, on “perspicuous presentations,” we offer new criticisms of ‘elucidatory’ readers of later Wittgenstein, such as Peter Hacker: we argue that their readings fail to connect with the radically therapeutic intent of the ‘perspicuous presentation’ concept, as an achievement‐term, rather than a kind of ‘objective’ mapping of (...) a ‘conceptual landscape.’Baker's Wittgenstein, far from being a ‘language policeman’ of the kind that often fails to influence mainstream philosophy, offers an alternative to the latent scientism of Wittgenstein's influential ‘elucidatory’ readers.

Changing patterns of political participation observed by political scientists over the past half-century undermine traditional democratic theory and practice. The vast majority of democratic theory, and deliberative democratic theory in particular, either implicitly or explicitly assumes the need for widespread citizen participation. It requires that all citizens possess the opportunity to participate and also that they take up this opportunity. But empirical evidence gathered over the past half-century strongly suggests that many citizens do not have a meaningful opportunity to participate (...) in the ways that many democratic theorists require, and do not participate in anything like the numbers that they believe is necessary. This paper outlines some of the profound changes that have been experienced by liberal democratic states in the 20th and early 21st Centuries, changes which are still ongoing, and which have resulted in declines in citizens participation and trust, the marginalisation of citizens from democratic life, and the entrenchment of social and economic inequalities which have damaged democracy. The paper challenges the conventional wisdom in rejecting the idea that the future of democracy lies in encouraging more widespread participation. The paper takes seriously the failure of the strategies adopted by many states to increase participation, especially among the poor, and suggests that instead of requiring more of citizens, we should in fact be requiring less of them. Instead of seeking to encourage more citizen participation, we should acknowledge that citizens will probably not participate in the volume, or in the ways, many democratic theorists would like, and that therefore we need an alternative approach: a regime which can continue to produce democratic outcomes, and which satisfies the requirements of political equality, in the absence of widespread participation by citizens.

1 Context The idea for the current issue of _Philosophia Scientiæ_ emerged from discussions which took place in the Manchester Ethnomethodology Reading Group. This reading group has its origins in Wes Sharrock’s weekly discussion groups, which have taken place in Manchester (UK) since the early 1970s. As the global Covid-19 pandemic hit in early 2020, the reading group moved online, facilitated by Phil Hutchinson and Alex Holder. Being an online reading group opened up participation to people beyond Northwest UK (...) and within weeks the group became global, with the membership including participants logging on from Canada, Czech Republic, Finland, France, Germany, Greece, Hong Kong, Japan, Macau, New Zealand, Spain, Sweden, and the USA. While the name of the group might indicate an exclusive focus on ethnomethodology, following the naming conventions for academic discussion groups, the name really fails to indicate both the heterogeneity of the group’s reading materials, the interests of t...

Although diagnosis is integral to the theory and practice of psychiatry, social scientists have not developed a comprehensive approach to diagnosis. This paper presents a preliminary outline of the issues which a sociology of diagnosis should integrate. These include bias and social control in psychiatric diagnosis, diagnosis as part of a new extension of the biopsychiatric medical model, and flaws in contemporary diagnostic categorization. These issues are then viewed in terms of professional practice styles, diagnostic biases, psychiatry's professional dominance over (...) the mental health field, and psychiatric hegemony over the clinical interaction with patients.

A predicate logic typically has a heterogeneous semantic theory. Subjects and predicates have distinct semantic roles: subjects refer; predicates characterize. A sentence expresses a truth if the object to which the subject refers is correctly characterized by the predicate. Traditional term logic, by contrast, has a homogeneous theory: both subjects and predicates refer; and a sentence is true if the subject and predicate name one and the same thing. In this paper, I will examine evidence for ascribing to Aristotle the (...) view that subjects and predicates refer. If this is correct, then it seems that Aristotle, like the traditional term logician, problematically conflates predication and identity claims. I will argue that we can ascribe to Aristotle the view that both subjects and predicates refer, while holding that he would deny that a sentence is true just in case the subject and predicate name one and the same thing. In particular, I will argue that Aristotle's core semantic notion is not identity but the weaker relation of constitution. For example, the predication ‘All men are mortal’ expresses a true thought, in Aristotle's view, just in case the mereological sum of humans is a part of the mereological sum of mortals. (shrink)

According to Hugh Mellor in Real Time II, assuming the logical independence of causal facts and the ‘law of large numbers’, causal loops are impossible because if they were possible they would produce inconsistent sets of frequencies. I clarify the argument, and argue that it would be preferable to abandon the relevant independence assumption in the case of causal loops.

When Aristotle introduces the perfect moods, he refers back to the dictum de omni et nullo, a semantic condition for universal affirmations and negations. There recently has been renewed interest in the question whether the dictum validates the assertoric syllogistic. I rehearse evidence that Aristotle provides a mereological semantics for universal affirmations and negations, and note that this semantics entails a nonstandard reading of the dictum, under which the dictum, in the presence of a minimal logical apparatus, indeed validates the (...) assertoric syllogistic. I argue that this mereological validation offers advantages over recent discussions in Morison, Malink, Ebert and Vlasits. (shrink)

Despite much discussion over the existence of moral facts, metaethicists have largely ignored the related question of their possibility. This paper addresses the issue from the moral error theorist’s perspective, and shows how the arguments that error theorists have produced against the existence of moral facts at this world, if sound, also show that moral facts are impossible, at least at worlds non-morally identical to our own and, on some versions of the error theory, at any world. So error theorists’ (...) arguments warrant a stronger conclusion than has previously been noticed. This may appear to make them vulnerable to counterarguments that take the possibility of moral facts as a premise. However, I show that any such arguments would be question-begging. (shrink)
