The singularity hypothesis is a radical hypothesis about the future of artificial intelligence on which self-improving artificial agents will quickly become orders of magnitude more intelligent than the average human. Despite the ambitiousness of its claims, the singularity hypothesis has been defended at length by leading philosophers and artificial intelligence researchers. In this paper, I argue that the singularity hypothesis rests on scientifically implausible growth assumptions. I show how leading philosophical defenses of the singularity hypothesis (Chalmers 2010, Bostrom 2014) fail (...) to overcome the case for skepticism. I conclude by drawing out philosophical implications of this discussion for our understanding of consciousness, personal identity, digital minds, existential risk, and ethical longtermism.

Contemporary mate preferences can provide important clues to human reproductive history. Little is known about which characteristics people value in potential mates. Five predictions were made about sex differences in human mate preferences based on evolutionary conceptions of parental investment, sexual selection, human reproductive capacity, and sexual asymmetries regarding certainty of paternity versus maternity. The predictions centered on how each sex valued earning capacity, ambition— industriousness, youth, physical attractiveness, and chastity. Predictions were tested in data from 37 samples drawn from (...) 33 countries located on six continents and five islands. For 27 countries, demographic data on actual age at marriage provided a validity check on questionnaire data. Females were found to value cues toresource acquisitionin potential mates more highly than males. Characteristics signalingreproductive capacitywere valued more by males than by females. These sex differences may reflect different evolutionary selection pressures on human males and females; they provide powerful cross-cultural evidence of current sex differences in reproductive strategies. Discussion focuses on proximate mechanisms underlying mate preferences, consequences for human intrasexual competition, and the limitations of this study. (shrink)

Epistemic nihilism for inquiry is the claim that there are no epistemic norms of inquiry. Epistemic nihilism was once the received stance towards inquiry, and I argue that it should be taken seriously again. My argument is that the same considerations which led us away from epistemic nihilism in the case of belief not only cannot refute epistemic nihilism for inquiry, but in fact may well support it. These include the argument from non-existence that there are no non-epistemic reasons for (...) belief; the linguistic argument that epistemic norms of belief are needed to capture the semantics of ordinary epistemic talk; and the argument from theoretical roles that epistemic norms are needed to play key theoretical roles for rational belief. I conclude by sketching an alternative Gibbardian picture on which norms of inquiry are all-things-considered norms governing action. (shrink)

Recent objections to epistemic permissivism have a metaepistemic flavor. Impermissivists argue that their view best accounts for connections between rationality, planning and deference. Impermissivism is also taken to best explain the value of rational belief and normative assessment. These objections pose a series of metaepistemic explanatory challenges for permissivism. In this paper, I illustrate how permissivists might meet their explanatory burdens by developing two permissivist metaepistemic views which fare well against the explanatory challenges.

A new wave of evidentialist theorizing concedes that evidentialism may be extensionally incorrect as an account of all-things-considered rational belief. Nevertheless, these _newer evidentialists_ maintain that there is an importantly distinct type of epistemic rationality about which evidentialism may be the correct account. I argue that natural ways of developing the newer evidentialist position face opposite problems. One version, due to Christensen (Philos Phenomenol Res 103:501–517, 2021), may correctly describe what rationality requires, but does not entail the existence of a (...) distinctively epistemic type of rationality. Another version, due to Maguire and Woods (Philos Rev 129:211–249, 2020), characterizes a normative concept that is both distinct and epistemic, but struggles to explain why this concept should be classified as a type of rationality. I conclude that the newer evidentialist strategy of extensional compromise may be less favorable to evidentialism than previously supposed. (shrink)

Over the last decade, philosophers of science have extensively criticized the epistemic superiority of randomized controlled trials for testing safety and effectiveness of new drugs, defending instead various forms of evidential pluralism. We argue that scientific methods in regulatory decision-making cannot be assessed in epistemic terms only: there are costs involved. Drawing on the legal distinction between rules and standards, we show that drug regulation based on evidential pluralism has much higher costs than our current RCT-based system. We analyze these (...) costs and advocate for evaluating any scheme for drug regulatory tests in terms of concrete empirical benchmarks, like the error rates of regulatory decisions. (shrink)

In this new textbook two Catholic ethicists with extensive teaching experience present a moral theology based on vision. David Matzko McCarthy and James M. Donohue draw widely from the Western philosophical tradition while integrating biblical and theological themes in order to explore such fundamental questions as What is good? The fourteen chapters in Moral Vision are short and thematic. Substantive study questions engage with primary texts and encourage students to apply theory to everyday life and common human experiences. The (...) book is accessibly written and flexible enough to fit into any undergraduate or seminary course on ethics. (shrink)

Conspiracy theories have a bad reputation. In the past, most philosophers have ignored the topic, vaguely supposing that conspiracy theories are obviously irrational and that they can be easily dismissed. The current philosophical interest in the subject results from a realisation that this is not so. Some philosophers have taken up the challenge of identifying and explaining the flaws of conspiracy theories. Other philosophers have argued that conspiracy theories do not deserve their bad reputation, and that conspiracy theorists do not (...) deserve their reputation for irrationality. This book represents both sides of this important debate. Aimed at a broad philosophical community, including epistemologists, political philosophers, and philosophers of history. It represents a significant contribution to the growing interdisciplinary debate about conspiracy theories. (shrink)

"Daimon Life is life-enchancing. To read it is to become richer in word." –John Llewelyn Disclosure of Martin Heidegger’s complicity with the National Socialist regime in 1933-34 has provoked virulent debate about the relationship between his politics and his philosophy. Did Heidegger’s philosophy exhibit a kind of organicism readily transformed into ideological "blood and soil"? Or, rather, did his support of the Nazis betray a fundamental lack of loyalty to living things? David Farrell Krell traces Heidegger’s political authoritarianism to (...) his failure to develop a constructive "life-philosophy"—his phobic reactions to other forms of being. Krell details Heidegger’s opposition to Lebensphilosophie as expressed in Being and Time, in an important but little-known lecture course on theoretical biology given in 1929–30 called "The Basic Concepts of Metaphysics," and in a recently published key text, Contributions to Philosophy, written in 1936–38. Although Heidegger’s attempt to think through the problems of life, sexual reproduction, behavior, environment, and the ecosystem ultimately failed, Krell contends that his methods of thinking nonetheless pose important tasks for our own thought. Drawing on and away from Heidegger, Krell expands on the topics of life, death, sexuality, and spirit as these are treated by Freud, Nietzsche, Derrida, and Irigaray. Daimon Life addresses issues central to contemporary philosophies of politics, gender, ecology, and theoretical biology. (shrink)

Abstract Gene-selectionists define fundamental terms in non-standard ways. Genes are determinants of difference. Phenotypes are defined as a gene’s effects relative to some alternative whereas the environment is defined as all parts of the world that are shared by the alternatives being compared. Environments choose among phenotypes and thereby choose among genes. By this process, successful gene sequences become stores of information about what works in the environment. The strategic gene is defined as a set of gene tokens that combines (...) ‘actor’ tokens responsible for an effect with ‘recipient’ tokens whose replication is thereby enhanced. This set of tokens can extend across the boundaries of individual organisms, or other levels of selection, as these are traditionally defined.

Using Kierkegaard's later religious writings as well as his earlier philosophical works, David Gouwens explores this philosopher's religious and theological thought, focusing on human nature, Christ, and Christian discipleship. He helps the reader approach Kierkegaard as someone who both analysed religion and sought to evoke religious dispositions in his readers. Gouwens discusses Kierkegaard's main concerns as a religious and, specifically, Christian thinker, and his treatment of religion using the dialectic of 'becoming Christian', and counters the interpretation of his religious (...) thought as privatistic and asocial. Gouwens appraises both the edifying discourses and the pseudonymous writings, including the particular problems posed by the latter. Between foundationalism and irrationalism, Kierkegaard's ideas are seen to anticipate the end of 'modernity', while standing at the centre of the Christian tradition. (shrink)

In this uplifting book, David Halpin suggests ways of putting the hope back into education, exploring the value of and need for utopian thinking in discussions of the purpose of education and school policy.

In this writing, David Hansen illuminates the aesthetic, moral, and epistemic meaning of bearing witness to teaching and teachers by drawing upon a recently completed field-based endeavor that included extensive school visits. Hansen shows how bearing witness can bring the inquirer close to the truth of teaching. However, the witness must undertake ethical work to ready her- or himself for the task. Even such readiness, which must be continuously re-won on each occasion, guarantees nothing. The witness in the classroom (...) must work with faith, hope, and a deep sense of the worthwhileness of teaching. Hansen suggests that the witness's practice as well as testimony regarding the work can have a valuable influence on the consciousness, and conscience, of all who concern themselves with teaching and teachers.

This book argues that hope is the indispensable precondition of religious practice and secular politics. Against dogmatic complacency and despairing resignation, David Newheiser argues that hope sustains commitments that remain vulnerable to disappointment. Since the discipline of hope is shared by believers and unbelievers alike, its persistence indicates that faith has a future in a secular age. Drawing on premodern theology and postmodern theory, Newheiser shows that atheism and Christianity have more in common than they often acknowledge. Writing in (...) a clear and engaging style, he develops a new reading of deconstruction and negative theology, arguing that they share a self-critical hope. By retrieving texts and traditions that are rarely read together, this book offers a major intervention in debates over the place of religion in public life. (shrink)

Byrne has demonstrated that although subjects can make deductively valid inferences of the modus ponens and modus tollens forms, these valid inferences can be suppressed by presenting an appropriate additional premise “If R then Q” with the original conditional “If P then Q”. This suppression effect challenges the assumption of all syntactic theories of conditional reasoning that formal rules of inference such as modus ponens is part of mental logic. This paper argues that both the syntactic and the mental model (...) accounts of the suppression effect are inadequate because they fail to give a principled account of the critical interpretive component involved in reasoning. In contrast, the relative salience model proposed in this study emphasized the centrality of the interpretative processes with the critical component being the relative salience of premises as judged by subjects on the basis of their prior knowledge activated in particular problem situations. Using 120 undergraduates and 120 policemen as subjects, predictions from the model were tested and confirmed in a suppression paradigm and evidence of convergent validity for the construct of salience were obtained. The results cannot be reconciled with either the syntactic view or the mental model view that have dominated theories of conditional reasoning. (shrink)

The decision-theoretic account of probability in the Everett or many-worlds interpretation, advanced by David Deutsch and David Wallace, is shown to be circular. Talk of probability in Everett presumes the existence of a preferred basis to identify measurement outcomes for the probabilities to range over. But the existence of a preferred basis can only be established by the process of decoherence, which is itself probabilistic.

Discussions of “indeterminacy” customarily distinguish two putative types: semantic indeterminacy (SI)—indeterminacy that’s somehow the product of the semantics of our words/concepts—and metaphysical indeterminacy (MI)—indeterminacy that exists as a mind/language-independent feature of reality itself. A popular and influential thought among philosophers is that all indeterminacy must be SI. In this paper we challenge this thought. Our challenge is guided by the question: What, exactly, does it take for a case of indeterminacy to count as SI? We argue that the only satisfactory (...) answer to this question must take SI to be grounded in a more basic type of MI. We conclude that SI cannot be made sense of without implicating MI. If there’s any indeterminacy, there must be indeterminacy in the world itself. (shrink)

This paper defends the view that the asymmetry of causation can be explained in terms of probabilistic relationships between event types. Papineau first explores three different versions of the "fork asymmetry", namely David Lewis' asymmetry of overdetermination, the screening-off property of common causes, and Spirtes', Glymour's and Scheines' analysis of probabilistic graphs. He then argues that this fork asymmetry is both a genuine phenomenon and a satisfactory metaphysical reduction of causal asymmetry. In his final section he shows how this (...) reduction can account for the relevance of causal direction to human agency, and in particular for the fact that we can manipulate causes to influence their effects, but not vice versa.

Many people think that promiscuity is morally acceptable, but rape and pedophilia are heinous. I argue, however, that the view of sexual ethics that underlies an acceptance of promiscuity is inconsistent with regarding (1) rape as worse than other forms of coercion or assault, or (2) (many) sex acts with willing children as wrong at all. And the view of sexual ethics that would fully explain the wrong of rape and pedophilia would also rule out promiscuity. I intend this argument (...) neither as a case against promiscuity nor as either a mitigation of rape or a partial defense of pedophilia. My purpose is to highlight an inconsistency in many people's judgements. Whether one avoids the inconsistency by extending or limiting the range of practices one condemns, will depend on which underlying view of the ethics of sex one accepts. (shrink)

The article offers an approach to inquiry about, the foundation of medical ethics by addressing three areas of conceptual presupposition basic to medical ethical theory. First, medical ethics must presuppose a view about the nature of medicine. it is argued that the view required by a cogent medical morality entails that medicine be seen both as a healing relationship and as a practical art. Three ways in which medicine inherently involves values and valuation are presented as important, i.e., in being (...) aimed at the good of health, in being a cognitive art evaluating towards that good, and as a manifestation of a virtuous disposition concerning that good. Finally, a value ontology drawn from these considerations is seen as necessarily underlying medical ethics. A set of three such basic values are promoted as crucial: the value of health; the value of the individual patient; and the value of altruism that mediates the class of potential patients. (shrink)

This paper examines potential predictors of ethical decisions regarding insider trading. An interactionist perspective is taken, in which person variables, situational variables, and the interaction of these two sets of variables are viewed as influencing ethical decisions. The results of our study support such a perspective. Ethical decisions regarding insider trading appear to be a function of a complex set of interacting variables related to both the person and the situation. The implications of these findings are discussed.

Increasingly, the world seems to shrink due to our ever-expanding technological and communication capacities. Correspondingly, our awareness of other cultures increases. This is especially true in the field of bioethics because the technological progress of medicine throughout the world is causing dramatic and challenging intersections with traditionally held values. Think of the use of pregnancy monitoring technologies like ultrasound to abort fetuses of the “wrong” sex in India, the sale of human organs in and between countries, or the disjunction between (...) the haves and the have-nots in South America when it comes to bone marrow transplants, while thousands of other children die for want of fundamental goods and services like clean water, basic inoculations, and food itself.

The early 20th-century French sociologist and philosopher Gabriel Tarde was an important critic of Durkheim's ontology of the social. Tarde developed a microsociological and ontological critique of the philosophical problems of resemblance and of variation underlying Durkheim's comparative sociology. Recently, thinkers such as Gilles Deleuze, Bruno Latour and Éric Alliez have begun to revisit Tarde and to develop a theme of the significance of Tarde's thought as a harbinger of postmodern theory. This article examines Tarde's theories in the light of (...) this new reception. It is shown that Tarde draws heavily from Leibniz's theory of the quantitative continuity of qualitative singulars in order to critique Durkheim's statistics-based social realism. While some key limitations of Tarde's critique are exposed, it is argued that Tarde finds a way to remain faithful to statistical sociology as a project even while calling radically into question the qualitative unity of the social.

In this paper, Isuggest that placebo effects, as we know them today, should be understood as experimental phenomena, low-level regularities whose causal structure is grasped through particular experimental designs with little theoretical guidance. Focusing on placebo interventions with needles for pain reduction -one of the few placebo regularities that seems to arise in meta-analytical studies- I discuss the extent to which it is possible to decompose the different factors at play through more fine-grained randomized clinical trials. My sceptical argument is (...) twofold. On the one hand, I argue that experiments alone are not enough to standardize interventions, and that it is necessary to include theories. On the other hand, I argue that the social interactions that seem to be part of placebo effects are difficult, if not impossible, to blind. Therefore, the measurement biases arising from the participants’ reactivity to the experimental setup cannot be controlled for. Further decomposition of placebo effects requires a theoretical account of the existing experimental regularities that may guide further tests. (shrink)

Did the impartiality of clinical trials play any role in their acceptance as regulatory standards for the safety and efficacy of drugs? According to the standard account of early British trials in the 1930s and 1940s, their impartiality was just rhetorical: the public demanded fair tests and statistical devices such as randomization created an appearance of neutrality. In fact, the design of the experiment was difficult to understand and the British authorities took advantage of it to promote their own particular (...) interests. I claim that this account is based on a poorly defined concept of experimental fairness . I present an alternative approach in which a test would be impartial if it incorporates warrants of non-manipulability. With this concept, I reconstruct the history of British trials showing that they were indeed fair and this fairness played a role in their acceptance as regulatory yardsticks. (shrink)

In this paper I offer an account of the normative dimension implicit in D. Bernoulli’s expected utility functions by means of an analysis of the juridical metaphors upon which the concept of mathematical expectation was moulded. Following a suggestion by the late E. Coumet, I show how this concept incorporated a certain standard of justice which was put in question by the St. Petersburg paradox. I contend that Bernoulli would have solved it by introducing an alternative normative criterion rather than (...) a positive model of decision making processes. (shrink)

Book synopsis: David-Hillel Ruben's new book pursues some novel and unusual standpoints in the philosophy of action. He rejects, for example, the most widely held view about how to count actions, and argues for what he calls a 'prolific theory' of act individuation. He also describes and argues against the two leading theories of the nature of action, the causal theory and the agent causal theory. The causal theory cannot account for skilled activity, nor for mental action. The agent (...) causalist theory unnecessarily reifies causings. He identifies an assumption that they share, and that most action theorists have assumed to be unproblematic and uncontroversial, that an action is, or entails the existence of, an event. Several different meanings to that claim are disentangled and in the most interesting sense of that claim, Ruben denies that it is true. His own alternative is simple and unpretentious: nothing informative can be said about the nature of action that explicates action in any other terms. Ruben sketches a theory of causal explanation of action that eschews the requirement for laws or generalisations, and this effectively quashes one argument for the oft-repeated view that no explanations of action can be causal, on the grounds that there are no convincing cases of laws of human action. He addresses a number of questions about the knowledge an agent has of his own actions, looking particularly at examples of pathological cases of action in which, for one reason or another, the agent does not know what he is doing. Inspiring and enlightening in its challenge to received wisdom, and in its convincing defence of some unfashionable positions, Action and its Explanation will be required reading for anyone working in this field.

This article examines the way in which public controversies affect regulatory science. It describes the controversy that unfolded in Europe around the use of the ninety-day rat-feeding tests for the risk assessment of genetically modified plants. This type of test had been criticized for almost two decades by toxicologists, nongovernmental organizations, and industry alike for its inability to capture the specific health effects of GM plants. But GM risk assessment experts showed great reluctance to move toward a more systematic use (...) of other tests, such as chronic two-year studies or toxicogenomic techniques, and made sure that official guidance continues to recommend the use of the ninety-day rat-feeding study. The article shows that these tactics of standardization are a defining feature of regulatory science, and a resource for toxicity experts to defend their authority and credibility against competing expertises that arise during controversies.

In June 1993, conjoined twins Amy and Angela Lakeberg became the focus of national attention.
