A physician and medical reformer enthused by the scientific and cultural progress of the Enlightenment as it took hold in Britain, Thomas Percival wrote on many topics, including public health and demography. His volume on medical ethics is considered the first modern formulation, and it and several of his other works are reissued in this series. This short book of improving tales, first published in 1777, and revised and enlarged in 1779, was originally written for his own children, and, (...) as he says, the articles 'are placed in the order in which they were written … as leisure allowed, or as the subjects of them were suggested'. The little stories contain lessons on obedience to parents, family affection, and kindness to animals, among many other examples of moral instruction. Percival refers to the book as 'Part the First', but a further collection seems never to have been published. (shrink)

We report on the small-scale (0.5 13 h - 1M, a large-scale bias of ~2.0 and a satellite fraction of 12 ± 2 per cent. Thus, these galaxies occupy haloes with average masses in between those of the higher redshift BOSS CMASS sample and the original SDSS I/II luminous red galaxy sample © 2012 The Authors Published by Oxford University Press on behalf of the Royal Astronomical Society © doi:10.1093/mnras/sts314.

We present a one per cent measurement of the cosmic distance scale from the detections of the baryon acoustic oscillations in the clustering of galaxies from the Baryon Oscillation Spectroscopic Survey, which is part of the Sloan Digital Sky Survey III. Our results come from the Data Release 11 sample, containing nearly one million galaxies and covering approximately 8500 square degrees and the redshift range 0.2 < z < 0.7. We also compare these results with those from the publicly released (...) DR9 and DR10 samples. Assuming a concordance Λ cold dark matter cosmological model, the DR11 sample covers a volume of 13 Gpc3 and is the largest region of the Universe ever surveyed at this density. We measure the correlation function and power spectrum, including density-field reconstruction of the BAO feature. The acoustic features are detected at a significance of over 7σ in both the correlation function and power spectrum. Fitting for the position of the acoustic features measures the distance relative to the sound horizon at the drag epoch, rd, which has a value of rd,fid = 149.28 Mpc in our fiducial cosmology. We find DV = at z = 0.32 and DV = at z = 0.57. At 1.0 per cent, this latter measure is the most precise distance constraint ever obtained from a galaxy survey. Separating the clustering along and transverse to the line of sight yields measurements at z = 0.57 of DA = and H =. Our measurements of the distance scale are in good agreement with previous BAO measurements and with the predictions from cosmic microwave background data for a spatially flat CDM model with a cosmological constant. © 2014 The Author Published by Oxford University Press on behalf of the Royal Astronomical Society.

In the film classic Blade Runner, the story explores the notion of personal identity through that of carefully crafted androids. Can an android have a personality; can androids be persons? The title of the original story by Philip K. Dick is Do Androids Dream of Electric Sheep? The story suggests that our sense of being a person depends on our having memories that connect us with our childhood. In the movie, the androids are only a couple of years old, but (...) have adult bodies. To complete them as persons they are given simulated memories of childhood. Some psychiatrists have decided that even humans dream only of electric sheep. I explore how Popper’s world 3 can help to defend a notion of personhood that can be used to criticize the thesis that persons are simply complex physical processes and that all their serious life-problems can be conceptualised as a form of physical illness.

A review of Steven Fuller's excellent book. Steve Fuller, professor of sociology at the University of Warwick, argues that, unfortunately for science, Kuhn won this debate. In the wake of Kuhn, science has come to be justified more by its paradigmatic pedigree than by its progressive aspirations. In other words, science is judged by whatever has come to be the dominant scientific community.

The authors of this collection fail to make clear the distinction between naturalistic and purely logical/methodological approaches to the philosophy of science. I also criticise Thomas Nickles's attempt to devise an explanatory method for discovery in science using programs that produce trial and error explorations of a domain, which he thinks replaces the need for a conjecture a refutation approach (cf. Popper and Campbell). Such programs embody undeclared conjectures in the way they are set up.

Modern medical ethics in the English-speaking world is commonly thought to derive from the medical philosophy of the Scotsman John Gregory (1725-1773) and his younger associates, the English Dissenter Thomas Percival (1740-1804) and the American Benjamin Rush (1745-1813). This book is the first extensive study of this suggestion. Dr Haakonssen shows how the three thinkers combined Francis Bacon's and the Scottish Enlightenment's ideas of the science of morals and the morals of science. She demonstrates how their medical ethics was (...) a successful adaptation of traditional moral ideas to the dramatically changing medical world especially the voluntary hospital. In accounting for the dynamics of this process, she rejects the anachronism that modern medical ethics was a new paradigm. (shrink)

I aim to illuminate foundational epistemological issues by reflecting on 'epistemic consequentialism'—the epistemic analogue of ethical consequentialism. Epistemic consequentialism employs a concept of cognitive value playing a role in epistemic norms governing belief-like states that is analogous to the role goodness plays in act-governing moral norms. A distinction between 'direct' and 'indirect' versions of epistemic consequentialism is held to be as important as the familiar ethical distinction on which it is based. These versions are illustrated, respectively, by cognitive decision-theory and (...) reliabilism. Cognitive decision-theory is defended, and various conceptual issues concerning it explored. A simple dilemma suggests that epistemic consequentialism has radical consequences. (shrink)

Mathilda Percival, libre de couleur, quitta Saint-Eustache, une petite île sous domination hollandaise, entre fin 1859 et début 1860. Elle s’embarqua pour une nouvelle vie sur l’île de Saint-Thomas, située aux Antilles danoises. Cet article s’appuie sur sept lettres de Mathilda à son mari. Elles font la lumière sur la vie et les difficultés des ouvrières émigrées au xixe siècle aux Caraïbes. Elles montrent que son expérience recoupe celle des employées de maison émigrées à cette époque, auxquelles l’émigration offrait (...) l’occasion d’éprouver un sentiment d’autonomie et d’émancipation. Si les motifs économiques étaient certainement l’une des motivations principales du départ de Mathilda pour Saint-Thomas, les raisons de son exil définitif sont probablement beaucoup plus complexes. Il semblerait que son travail lui ait donné satisfaction. En outre, alors que l’historiographie sur la migration des femmes caribéennes porte principalement sur le xxe siècle (après la construction du Canal de Panama et s’accélérant après 1960), on sait peu sur l’émigration des femmes au milieu du xixe siècle, après l’abolition de l’esclavage. On en sait encore moins sur les Caraïbes non britanniques, constamment négligées par la recherche – une lacune à laquelle tente de remédier cet article à travers l’étude de ces lettres. (shrink)

The second uses epis utility to evaluate beliefs and partial beliefs themselves, as well as actions, such as gathering information in the course of an inquiry. I express scepticism about the notion of acceptance required for the first project, and argue that the second kind of project can be fruitful only with a richer notion of epistemic utility than has yet been developed.

Although many researchers theorize that primitive numerosity processing abilities may lay the foundation for whole number concepts, other classes of numbers, like fractions, are sometimes assumed to be inaccessible to primitive architectures. This research presents evidence that the automatic processing of nonsymbolic magnitudes affects processing of symbolic fractions. Participants completed modified Stroop tasks in which they selected the larger of two symbolic fractions while the ratios of the fonts in which the fractions were printed and the overall sizes of the (...) compared fractions were manipulated as irrelevant dimensions. Participants were slower and less accurate when nonsymbolic dimensions of printed fractions were incongruent with the symbolic comparison decision. Results indicated a robust basic sensitivity to nonsymbolic ratios that exceeds prior conceptions about the accessibility of fraction values. Results also indicated a congruity effect for overall fraction size, contrary to findings of prior research. These findings have implications for extending theory about the nature of human number sense and mathematical cognition more generally. (shrink)

Originally published in 1940, this book contains an expanded English translation of Books 8 and 9 of Aristotle's Nicomachean Ethics. These two books are devoted to a discussion on the nature of friendship and the role it played in Greek life, and Percival supplies an introduction with a background to the subject of ancient friendship prior to Aristotle's formulation. This book will be of value to anyone with an interest in ancient friendship or the philosophy of Aristotle.

PaceZagzebski, there is no route from the value of knowledge to a non–reliabilist virtue–theoretic epistemology. Her discussion of the value problem is marred by an uncritical and confused employment of the notion of a “state” of knowledge, an uncritical acceptance of a “knowledge–belief” identity thesis, and an incoherent presumption that the widely held thought that knowledge is more valuable than true belief amounts to the view that knowledge is a state of true belief having an intrinsic property which a state (...) of ‘mere” true belief lacks. Her arguments against a “machine–product” conception of knowledge are undermined by these flaws, while the alternative “agent–act” model she recommends is unattractive, at odds with the knowledge–belief identity thesis she favours, and no solution to the problem of the value of knowledge she poses. I end with the observation that her version of virtue–theoretic epistemology points in the direction of cognitive decision–theoretic norms, and I briefly discuss the bearing of this fact upon her viewpoint.

Richard Dawkins tries to establish an analogy between computer viruses and theistic belief systems, analyzing the latter in terms of his concept of the meme. The underlying thrust of Dawkins' argument is to downplay the role of truth and logic in the survival of theories and to emphasize humankind's helpless liability to incurable infection by doctrines that Dawkins regards as absurd. Dawkins supplies a list of "symptoms” of mind-infection. However, on closer investigation these characteristics are found to be either rather (...) weak protection against criticism or quite virtuous. Dawkins relies on a crude justificationism that could just as well be called a mind-virus. Applying Dawkins’ own selection of the general characteristics of a good meme protector and propagator leads to the conclusion that his particular theistic examples would actually impair copyability. -/- Scientific theories are better examples of memes with high longevity, fecundity, and fidelity. A Darwinian analysis of wishful and fearful thinking as useful to hypotheses-testing and goal-seeking organisms undermines Dawkins' attribution of absolute irrational stubbornness to theists. To counterbalance Dawkins' emphasis on the propagation of the absurd, I rehabilitate the Socratic emphasis on the importance of truth and logic in rhetoric, interpreted broadly as the theory of the successful propagation of a message. I use Popper's notion of situational analysis, and an evolutionary perspective to argue that rational standards of a message enhance its copyability. I further apply Popper’s notions of World 3, 2, and 1 to memes; this helps us see the perpetuation of a doctrine as a logical task. (shrink)

When making decisions, humans can observe many kinds of information about others' activities, but their effects on performance are not well understood. We investigated social learning strategies using a simple problem-solving task in which participants search a complex space, and each can view and imitate others' solutions. Results showed that participants combined multiple sources of information to guide learning, including payoffs of peers' solutions, popularity of solution elements among peers, similarity of peers' solutions to their own, and relative payoffs from (...) individual exploration. Furthermore, performance was positively associated with imitation rates at both the individual and group levels. When peers' payoffs were hidden, popularity and similarity biases reversed, participants searched more broadly and randomly, and both quality and equity of exploration suffered. We conclude that when peers' solutions can be effectively compared, imitation does not simply permit scrounging, but it can also facilitate propagation of good solutions for further cumulative exploration.

For twenty years, D. H. Mellor has promoted an influential defence of a view of time he first called the ‘tenseless’ view, but now associates with what he calls the ‘B-theory.’ It is his defence of this view, not the view itself, which is generally taken to be novel. It is organized around a forcefully presented attack on rival views which he claims to be a development of McTaggart's celebrated argument that the ‘A-series’ is contradictory. I will call this attack (...) ‘Mellor's McTaggart.’ Although it has received much critical attention, it has not been well understood. For one thing, it has changed over the years in a way that is little appreciated. Whereas Mellor's original version amounts to a dilemma each horn of which contains a single strand of argument, later statements of the first horn contain a second strand of argument unannounced. I shall be concerned to disentangle these strands. I shall also show them to have been largely anticipated by Gareth Evans. However, my main aim is not the clarification of Mellor's McTaggart, but its refutation. I shall show that there is a rival to Mellor's view of time against which the first horn of the dilemma begs the question both as originally presented, and as supplemented. This rival is a ‘Priorean’ version of the ‘presentist’ doctrine that only what is present exists. Although Prior himself gave McTaggart's own argument short shrift, in refuting Mellor's development of it I do not merely resurrect Prior's moves. Mellor's McTaggart introduces specifically semantic considerations. It focuses not as McTaggart did on presentness and futurity etc., but on the truth-values of tokens of propositions in which presentness and futurity etc. are ascribed. Consequently, its refutation requires an answer, from the perspective of a presentist metaphysics, to a question which came to the fore only after Prior's death. The question is this: How should semantic theory be developed in the light of the need for a theory of linguistic understanding? Though Evans flirted with the issue of how this question should be answered from a presentist perspective, the answer he articulates is wrong. I shall do no more than sketch the correct answer.

It is one thing for a scientist to speak a language in which he can conduct and communicate his investigations, another for him to possess a reflective understanding enabling him to explain the nature and workings of that language. Many who have sought such an understanding have held that the concepts of “meaning,” “reference,” and “theoretical term” play a crucial role in developing it. But others — instrumentalist skeptics about reference, Quinean skeptics about meaning, and skeptics about the theory/observation distinction (...) — have denied this. (shrink)

Recent research in numerical cognition has begun to systematically detail the ability of humans and nonhuman animals to perceive the magnitudes of nonsymbolic ratios. These relationally defined analogs to rational numbers offer new potential insights into the nature of human numerical processing. However, research into their similarities with and connections to symbolic numbers remains in its infancy. The current research aims to further explore these similarities by investigating whether the magnitudes of nonsymbolic ratios are associated with space just as symbolic (...) numbers are. In two experiments, we found that responses were faster on the left for smaller nonsymbolic ratio magnitudes and faster on the right for larger nonsymbolic ratio magnitudes. These results further elucidate the nature of nonsymbolic ratio processing, extending the literature of spatial–numerical associations to nonsymbolic relative magnitudes. We discuss potential implications of these findings for theories of human magnitude processing in general and how this general processing relates to numerical processing. (shrink)

The question as to whether some objects are possible worlds that have an initial segment in common, i.e. so that their fusion is a temporal tree whose branches are possible worlds, arises both for those who hold that our universe has the structure of a temporal tree and for those who hold that what there is includes concrete universes of every possible variety. The notion of “possible world” employed in the question is seen to be the notion of an object (...) of a kind such that objects of that kind play a certain theoretical role. Lewis’s discussion of the question is thereby clarified but is nevertheless inadequate; his negative answer is correct but even from his combinatorialist viewpoint the rationale he provides for this answer is misguided. I explain why the combinatorialist advocate of concrete plenitude should hold that no object is a tree of possible worlds. Then I explain that for a different reason the nomic essentialist advocate of concrete plenitude should hold this much too. (shrink)

Comic moralism holds that some moral properties impact negatively on the funniness of certain items that possess them. Strong versions of the doctrine deem the impact to be devastating: the possession of such a property by one of these items ensures the item is not funny. Weak versions deem the impact merely damaging: any funniness one of the items possesses is diminished, but not destroyed, by its possession of the property. Various species of comic moralism hold, respectively, various moral properties (...) to impact negatively on funniness. For example, one species holds as much of the property “manifests attitudes that are morally wrong,” but other species hold as much of different moral properties. Comic moralism, or a species of it, can be unrestricted, or restricted, depending on whether it pertains to all the items that possess the negatively impacting moral property or properties, or to just a subset of these items.
