This study forms a part of a larger investigation of the influence of the philosophy of Heraclitus of Ephesus on modern poetry. T. S. Eliot, to mention the best known of the many poets inspired by Heraclitus, selected two Heraclitus fragments (B 2 and B 60) as epigraphs for his “Burnt Norton”, the first of his Four Quartets. Eliot explained that he was drawn to the fragments because of their ‘ambiguity’ and ‘extraordinary poetic suggestiveness’. Similarly, in ‘This Solitude of Cataracts’, (...) Wallace Stevens spoke of ‘the flecked river which kept flowing and never the same way twice’ and elsewhere noted the ‘inherently poetic quality’ of many Heraclitean sayings. To gain some sense of the nature and magnitude of Heraclitus’ legacy for modern poetry we must first explore his vision of ‘a fiery cosmos being kindled in measures and extinguished in measures’ and a river into which one cannot step twice. -/- .

The "grassroots turn" in bioethical discussions about justice in allocation of health care resources has attracted a great deal of support; in the absence of a convincing theory of justice in rationing, democratic decisionmaking concerning priority setting emerges with a kind of inevitability. Yet there remain suspicions about this approach – most importantly, worries about the socially corrosive impact of explicit, public decisionmaking that in effect sets a price on the lives of persons. These worries have been quieted, particularly by (...) the work of Leonard Fleck, but not altogether stilled. I explore more sympathetically the ideals to which concerns about public rationing somewhat dimly respond, and suggest constraints on priority setting discussions which might accommodate those ideals rather better.

Readers of “lives” of the famous know well the tendency of biography, and especially autobiography, to become steadily less interesting as the subject grows older. A predictable record of challenges met, enemies shafted, honours received and great men encountered often succeeds an account of a childhood that is a highly-coloured and unique emotional drama. Often the best pages are those on the subject’s schooldays, when the personality first tangles with the public realm. As Barry Oakley says of school in a (...) piece quoted in the book’s preface: “Like the stage, it’s an image of life: life accelerated, life concentrated, life more formidable.” The project of selecting just the highlights of all the stories of Australians’ schooldays promises, then, a high payoff if it is well done. It is a high-risk enterprise, though: a pointillist canvas brilliant in each fleck may easily look like mud from a distance. There are well over a hundred authors here, with only three pages or so each to paint a vignette of school. In fact, the result is an enormous success. The editors have a sure eye, and they and their research assistant, Pamela Williams, have put in the work to find the goods. Almost every piece is gripping, and quite different from the others. The total effect is additive, and is an unexampled insight into how the Australia we know came into being. The classics are there: Henry Lawson and Patrick White, Seven Little Australians and The Getting of Wisdom, Donald Horne, Barry Humphries and Clive James. So are the many unknowns whose recollections take us into obscure corners. If there is one overall theme, it is that of sameness, difference and “fitting in”. The effect of the accumulated evidence is rather more subtle than the received ideas on “identity and difference”, multiculturalism and so on. School is where the strangeness of one’s own family, or of one’s own personality, meets the social world – itself perhaps no less weird, objectively speaking, but possessed of resources for ensuring conformity.

During the past century and a half historians and sociologists have often shown signs of considerable simplicity of mind when assessing the motivating forces behind the men whose deeds they are studying, and those attaining the most flattering notoriety in the intellectual world have been among the simplest. From the early nineteenth century, beginning with the fall of Napoleon, there is a tendency to present the historical disciplines as sciences: the re-creative anecdote is greeted with increasing disdain, and sociology undergoes (...) its act of baptism. The Revolution of 1789 and the epic of imperial France are events of such dimension that it is difficult to associate them with the conscious designs of a few individuals. No longer a muse, Clio becomes a goddess. In War and Peace Tolstoi ironically treats historians of the old school who pretend to offer the key to the Revolution “in exposing the deeds and gestures of a few dozen men in one building in the city of Paris.” The French emperor's gallop into Russia and the stubborn but apparently passive resistance offered by Kutuzov—these are facts in which Tolstoi sees the manifestation of forces far surpassing the play of a few human wills. Tolstoi's manner in extolling Kutuzov is typical: Kutuzov is not a visionary; he shows no signs of genius, but with humble and patient fervor he turns aside all obstacles which might stifle the voice of popular instinct. Thirty years before Tolstoi, in a letter to his fiancée, Georg Büchner stated the case in another good example of this type of thinking: “I have studied the history of the Revolution. … I find in human nature a frightening equality, in the condition of man an ineluctable power conferred at once upon all and upon no one. The individual is but a fleck of foam upon the wave, greatness merely the result of chance, the power of genius a puppet show, a ridiculous struggle against a law of iron.” Men are interesting insofar as they are representative. Saint-Simon, mentor of Auguste Comte and father of sociology, declares that the great men of the world merely play the role assigned to them in historical evolution. According to Saint-Simon, the sixteenth century, an age of theology, gave birth to theologian-kings: Charles V and Henry VIII. Because he is a theologian, Henry VIII easily prevails over gallant and witty Francis I. The eighteenth century, a siècle of philosophy, “counts but two great names among its sovereigns: Catherine and Frederick the Great, friends of philosophers and patrons of philosophy.” Seen in this light, the features of the individual become blurred and shadowy. History is admired instead— history which, often with material of mediocre quality, builds solid edifices. But, faced with the astonishing drama played out by Napoleon himself, Tolstoi merely shrugs his shoulders, while following step by step simple men like Tostopchin or Kutuzov, who are obviously the mere instruments of history. Heine, who went through a Saint-Simonian phase, is amazed that Luther, that rough, gross monk whose brain was clouded by anxiety and superstition, so easily wielded the battering ram that shattered the old medieval world. In the 1830’s Auguste Comte foresees a “history without proper names,” a definition which is of prime importance in the analysis we are undertaking here. But, a hundred years later, Maxime Leroy, nourished on both Comte and Sainte-Beuve, draws more subtly shaded definitions: history becomes a “sociology containing proper names.”. (shrink)

According to the dogmatism puzzle, for any S and any p, if S knows that p, then she’s entitled to be dogmatic about p, and so disregard any evidence against p, for she knows that (or is in a position to know that) that evidence is misleading. But this seems clearly problematically dogmatic. The standard solution to the dogmatism puzzle involves appealing to the view that acquiring new evidence (even misleading evidence) can undermine one’s knowledge that p. That’s why one (...) can’t rightly disregard any future evidence against p. This solution to the dogmatism puzzle has come to be called ‘the defeat solution’. Maria Lasonen-Aarnio has recently argued, however, that the defeat solution leaves unsolved a partial defeat version of the dogmatism puzzle, where some subject acquires weak misleading evidence against p, but, since it is weak, it doesn’t rob her of knowledge that p. Lasonen-Aarnio argues that solving this partial defeat version of the dogmatism puzzle requires those who endorse the defeasibility of knowledge to either go dogmatist or reject an extremely plausible principle that she calls ‘Entitlement’ (roughly, for any S and any e, if S knows that evidence e is misleading, then S can rightly disregard e). In this paper, however, I argue that defeasibilists face no such challenge from any version of the dogmatism puzzle, since the dogmatism puzzle, in both its original and partial defeat form, rests on an assumption that we have very good reason to think is mistaken. Specifically, the assumption that, for any S and any p, if S knows that p, then S knows (or is in a position to know) that any evidence against p is misleading. I further argue that rejecting this assumption also yields a neat solution to the dogmatism puzzle involving intention originally proposed by Saul Kripke and recently adapted by R.E. Fraser.

Abstract:Disturbing cases continue to be published of patients declared brain dead who later were found to have a few intact brain functions. We address the reasons for the mismatch between the whole-brain criterion and brain death tests, and suggest solutions. Many of the cases result from diagnostic errors in brain death determination. Others probably result from a tiny amount of residual blood flow to the brain despite intracranial circulatory arrest. Strategies to lessen the mismatch include improving brain death determination training (...) for physicians, mandating a test showing complete intracranial circulatory arrest, or revising the whole-brain criterion.

Baggs and Chemero (2018)propose that certain tensions between enaction and ecological psychology arise due different interpretations about what is meant by the “environment.” In the enactive approach the emphasis is on the umwelt, which describes the environment as the “meaningful, lived surroundings of a given individual.” The ecological approach, on the other hand, emphasises what they refer to as the habitat “the environment as a set of resources for a typical, or ideal, member of a species.” By making this distinction, (...) these authors claim they are able to retain the best of both the ecological and the enactive approaches. Herein I propose an account of the individuation of habits that straddles this distinction, what I call a compatabilist account. This is done in two parts. The first part teases out a host of compatibilities that exist between the enactive account as developed byDi Paolo et al. (2017)and the skilled intentionality framework as developed byBruineberg and Rietveld (2014)andRietveld and Kiverstein (2014). In part two these compatibilities are brought together with the philosophy of Gilbert Simondon to develop the notion of enhabiting. Enhabiting describes a set of ongoing processes by which an umwelt emerges from and is reproduced within the relationship between an embodied subject and their habitat. Thus, enhabiting points toward a point of intersection between enaction and ecological psychology. To enhabit is bring forth (to enact), within (to inhabit). (shrink)

Research involving human subjects is much more stringently regulated than many other nonresearch activities that appear to be at least as risky. A number of prominent figures now argue that research is overregulated. We argue that the reasons typically offered to justify the present system of research regulation fail to show that research should be subject to more stringent regulation than other equally risky activities. However, there are three often overlooked reasons for thinking that research should be treated as a (...) special case. First, research typically involves the imposition of risk on people who do not benefit from this risk imposition. Second, research depends on public trust. Third, the complexity of the moral decision making required favors ethics committees as a regulative solution for research. (shrink)

In a seminal 1977 article, Rumelhart argued that perception required the simultaneous use of multiple sources of information, allowing perceivers to optimally interpret sensory information at many levels of representation in real time as information arrives. Building on Rumelhart's arguments, we present the Interactive Activation hypothesis—the idea that the mechanism used in perception and comprehension to achieve these feats exploits an interactive activation process implemented through the bidirectional propagation of activation among simple processing units. We then examine the interactive activation (...) model of letter and word perception and the TRACE model of speech perception, as early attempts to explore this hypothesis, and review the experimental evidence relevant to their assumptions and predictions. We consider how well these models address the computational challenge posed by the problem of perception, and we consider how consistent they are with evidence from behavioral experiments. We examine empirical and theoretical controversies surrounding the idea of interactive processing, including a controversy that swirls around the relationship between interactive computation and optimal Bayesian inference. Some of the implementation details of early versions of interactive activation models caused deviation from optimality and from aspects of human performance data. More recent versions of these models, however, overcome these deficiencies. Among these is a model called the multinomial interactive activation model, which explicitly links interactive activation and Bayesian computations. We also review evidence from neurophysiological and neuroimaging studies supporting the view that interactive processing is a characteristic of the perceptual processing machinery in the brain. In sum, we argue that a computational analysis, as well as behavioral and neuroscience evidence, all support the Interactive Activation hypothesis. The evidence suggests that contemporary versions of models based on the idea of interactive activation continue to provide a basis for efforts to achieve a fuller understanding of the process of perception.

This paper defends an invariance-based account of laws of nature: Laws are generalizations that remain invariant under various sorts of changes. Alternatively, laws are generalizations that exhibit a certain kind of independence from background conditions.

I present a new perspective on the meaning of indistinguishability of classical particles. This leads to a solution to the problem in statistical mechanics of justifying the inclusion of a factor N! in a probability distribution over the phase space of N indistinguishable classical particles.

Background The ethical governance of Artificial Intelligence (AI) in health care and public health continues to be an urgent issue for attention in policy, research, and practice. In this paper we report on central themes related to challenges and strategies for promoting ethics in research involving AI in global health, arising from the Global Forum on Bioethics in Research (GFBR), held in Cape Town, South Africa in November 2022. Methods The GFBR is an annual meeting organized by the World Health (...) Organization and supported by the Wellcome Trust, the US National Institutes of Health, the UK Medical Research Council (MRC) and the South African MRC. The forum aims to bring together ethicists, researchers, policymakers, research ethics committee members and other actors to engage with challenges and opportunities specifically related to research ethics. In 2022 the focus of the GFBR was “Ethics of AI in Global Health Research”. The forum consisted of 6 case study presentations, 16 governance presentations, and a series of small group and large group discussions. A total of 87 participants attended the forum from 31 countries around the world, representing disciplines of bioethics, AI, health policy, health professional practice, research funding, and bioinformatics. In this paper, we highlight central insights arising from GFBR 2022. Results We describe the significance of four thematic insights arising from the forum: (1) Appropriateness of building AI, (2) Transferability of AI systems, (3) Accountability for AI decision-making and outcomes, and (4) Individual consent. We then describe eight recommendations for governance leaders to enhance the ethical governance of AI in global health research, addressing issues such as AI impact assessments, environmental values, and fair partnerships. Conclusions The 2022 Global Forum on Bioethics in Research illustrated several innovations in ethical governance of AI for global health research, as well as several areas in need of urgent attention internationally. This summary is intended to inform international and domestic efforts to strengthen research ethics and support the evolution of governance leadership to meet the demands of AI in global health research.

Several prominent writers including Norman Daniels, James Sabin, Amy Gutmann, Dennis Thompson and Leonard Fleck advance a view of legitimacy according to which, roughly, policies are legitimate if and only if they result from democratic deliberation, which employs only public reasons that are publicised to stakeholders. Yet, the process described by this view contrasts with the actual processes involved in creating the Affordable Care Act (ACA) and in attempting to pass the Health Securities Act (HSA). Since the ACA (...) seems to be legitimate, as the HSA would have been had it passed, there seem to be counterexamples to this view. In this essay, I clarify the concept of legitimacy as employed in bioethics discourse. I then use that clarification to develop these examples into a criticism of the orthodox view–that it implies that legitimacy requires counterintuitively large sacrifices of justice in cases where important advancement of healthcare rights depends on violations of publicity. Finally, I reply to three responses to this challenge: (1) that some revision to the orthodox view salvages its core commitments, (2) that its views of publicity and substantive considerations do not have the implications that I claim and (3) that arguments for it are strong enough to support even counterintuitive results. My arguments suggest a greater role for substantive considerations than the orthodox view allows. (shrink)

In the wake of Locke’s Essay, empiricists faced the challenge of giving an empiricist account of the origins of moral knowledge. Locke did not rise to this challenge and relied on revelation as the source of moral knowledge. Other empiricists, including Hume and Hutcheson, opted for either emotivism or subjectivism. Clarke and others opted for rationalism and non-naturalism. In contrast, Catharine Cockburn’s meta-ethics combined Locke’s empiricism with naturalism. She held that moral good is natural good and that natural good is (...) known just as any other matters of natural fact are known: empirically. Cockburn’s position was unusual for its time, and the full originality and appeal of her meta-ethical position have not been fully appreciated. (shrink)

Certain discussions about “relativism” in the philosophy of Zhuangzi turn on the question of the morality of his dao 道. Some commentators, most notably Robert Eno, maintain that there is no ethical value whatsoever to Zhuangzi’s dao as presented in the Cook Ding episode and other “knack passages.” In this essay, it is argued that there is indeed a moral dimension to Cook Ding’s dao. One way to recognize it is to explore the similarity between that dao and John Dewey’s (...) notion of educational method. There are moral traits that Dewey can appeal to in recommending his method. It is argued here that these traits represent the moral features of Cook Ding’s dao as well. (shrink)

This article criticises David Chalmers’ ‘Reality+’ by interrogating its distinction of virtual reality (VR) from 2D, non-VR video games, a distinction made on the grounds that VR is immersive and these types of video games are not because immersion is a distinct characteristic of 3D perceptually represented VR. Building on the Balcerak Jacksons’ account of ‘representational immersion’, which they acknowledge has ‘perceptual’ and ‘non-perceptual’ elements, I develop an account of ‘non-perceptual representational immersion’ and use it to critique Chalmers’ treatment of (...) VR, immersion, and video games, indirectly problematizing his central ontological claim that ‘virtual reality is genuine reality’ and the reflections he makes about future society which rest upon it. I argue that video games are rich in non-perceptual representational immersion, which includes the representation of non-perceptual information about the structure and behaviour of a virtual world and its systems, the non-perceptual cognitive states that are generated in the player by the virtual world, and the immersion which comes from the constitutively cognitive nature of the player’s engagement with the virtual world, a cognitive engagement construed in an enactive sense. These are just as crucial to the phenomenon of digital immersion as perception. Immersion generally is a much more complicated phenomenon than Chalmers allows for, and it is better conceived as taking place on a spectrum which includes both 3D and 2D experiences of virtual worlds, not as hinging on 3D perceptual representation. I use ‘immersive simulation’ games as a case study. (shrink)

Notably absent from much of the psychological literature on emotion regulation are attempts to answer explicitly normative questions about the phenomenon. It is one thing to explain how emotional states are regulated. It is another thing to say something about what reasons there are to regulate our emotions, whether and why we might sometimes be obligated to regulate our emotions, and how we regulate our emotions well, or optimally. This paper is an attempt at the latter task, focused specifically on (...) a type of emotion regulation also receiving little attention in the literature—what I call dispositional emotion regulation. Dispositional regulation occurs, when it does, at some point or period of time significantly prior to the onset of affected emotional states or episodes, and by means of modifying the subject’s emotional dispositions. And it is done well, or optimally, I argue, when it is done with an aim toward achieving and maintaining a coherent and comprehensible self, in the sense Shaftesbury had in mind. (shrink)

SummaryThe effects of infant suckling patterns on the post-partum resumption of ovulation and on birth-spacing are investigated among the Gainj of highland New Guinea. Based on hormonal evidence, the median duration of lactational anovulation is 20·4 months, accounting for about 75% of the median interval between live birth and next successful conception. Throughout lactation, suckling episodes are short and frequent, the interval changing slowly over time, from 24 minutes in newborns to 80 minutes in 3-year olds. Maternal serum prolactin concentrations (...) decline in parallel with the changes in suckling patterns, approaching the level observed in non-nursing women by about 24 months post-partum. A path analysis indicates that the interval between suckling episodes is the principal determinant of maternal prolactin concentration, with time since parturition affecting prolactin secretion only in so far as it affects suckling frequency. The extremely prolonged contraceptive effect of breast-feeding in this population thus appears to be due to a slow decline in suckling frequency with time since parturition and absence of a decline over time in hypothalamic–pituitary responsiveness to the suckling stimulus.

A timely and accessible synthesis of the strengths, weaknesses and reality of science through the eyes of a practicing scientist.

Nominal logic is a variant of first-order logic in which abstract syntax with names and binding is formalized in terms of two basic operations: name-swapping and freshness. It relies on two important principles: equivariance (validity is preserved by name-swapping), and fresh name generation ("new" or fresh names can always be chosen). It is inspired by a particular class of models for abstract syntax trees involving names and binding, drawing on ideas from Fraenkel-Mostowski set theory: finite-support models in which each value (...) can depend on only finitely many names. Although nominal logic is sound with respect to such models, it is not complete. In this paper we review nominal logic and show why finite-support models are insufficient both in theory and practice. We then identify (up to isomorphism) the class of models with respect to which nominal logic is complete: ideal-supported models in which the supports of values are elements of a proper ideal on the set of names. We also investigate an appropriate generalization of Herbrand models to nominal logic. After adjusting the syntax of nominal logic to include constants denoting names, we generalize universal theories to nominal-universal theories and prove that each such theory has an Herbrand model.

For over a decade John Searle's ingenious argument against the possibility of artificial intelligence has held a prominent place in contemporary philosophy. This is not just because of its striking central example and the apparent simplicity of its argument. As its appearance in Scientific American testifies, it is also due to its importance to the wider scientific community. If Searle is right, artificial intelligence in the strict sense, the sense that would claim that mind can be instantiated through a formal (...) program of symbol manipulation, is basically wrong. No set of formal conditions can provide us with the characteristic feature of mind which is the intentionally of its mental contents. Formally regarded, such intentionally is an irreducible primitive. It cannot be analyzed into non-intentional (purely syntactic, symbolic) components. This paper will argue that this objection is based on a misunderstanding. Intentionality is not simply something given which is incapable of further analysis. It only appears so when we mistakenly abstract it from time. When we regard its temporal structure, it shows itself as a rule-governed, synthetic process, one capable of being instantiated both by machines and men. (shrink)

In discussing the Bible as literature, I am simply going to assume that the Bible, particularly in the King James version, is great literature. I am also going to take for granted the fact that its stories and themes have continually sparked the literary imagination of the West. From the story of Adam and Eve in the Garden to that of the Resurrection we have a set of symbols, motifs, and themes whose reworking has been the subject of the (...) bulk of our literature. I am not going to discuss this influence, nor even discuss the Bible as a piece of literature, i.e., as a particular literary work. What I am going to do is to focus on what is involved in our taking it as literature. More particularly, I am going to look at how we approach questions of truth in a literary work. I am going to ask how far we can push this approach when we come to read the Bible. What are the limits in reading the Bible as literature? When does the notion of “truth” as it arises in a literary text begin to fail us. That it will fail us at a certain point is implicit in the Bible’s claim to be “sacred scripture” or “revelation.” If we take this claim seriously, we naturally have a special approach to the “truth” its text contains. But what precisely is this approach? This is what I want to explore. In other words, my goal in exploring the limits of the literary approach to the Bible is to gain some insights into the sacred character of its text and how we should approach it. §1. Truth and the literary text. The most common, if often overlooked feature of a successful literary work is that of presenting us with a world In a certain sense, it succeeds by having inherent standards for what can belong to it, of what fits in with its sense and what does not. Having such standards, it presents us with that unified sense that makes a world a world, that is, that makes it an ordered whole.. (shrink)

Some members of the Vienna Circle argued for a coherence theory of truth. Their coherentism is immune to standard objections. Most versions of coherentism are unable to show why a sentence cannot be true even though it fails to cohere with a system of beliefs. That is, it seems that truth may transcend what we can be warranted in believing. If so, truth cannot consist in coherence with a system of beliefs. The Vienna Circle's coherentists held, first, that sentences are (...) warranted by coherence with a system of beliefs. Next they drew upon their verification theory of meaning, a consequence of which is that truth cannot transcend what can be warranted. The coherence theory of knowledge and verificationism together entail that truth cannot transcend what can be warranted by coherence with a system of beliefs. The Vienna Circle's argument for coherentism is strong and anticipates contemporary anti-realism. (shrink)
