Tacitus' portrayal of the emperor Tiberius has called forth a superabundance of comment. This note, therefore, will be brief and directed to a single question, provoked by some of this recent work; namely, how far are we entitled to draw conclusions as to Tacitus' powers of psychological analysis or as to his philosophical outlook on the basis of this portrayal? A generation ago Marsh concluded that Tacitus' psychology was superficial: ‘That a man could successfully conceal his real character till he (...) was nearing seventy and then throw off the disguise did not seem to Tacitus in any way improbable.’ Arruntius, he concluded, must be regarded ‘a better psychologist than Tacitus’ in view of his different judgement of Tiberius as recorded by the latter.

In the middle of last century metaphysics was widely criticized, ridiculed, and committed to the flames. During this period a handful of philosophers, against several anti-metaphysical trends, defended metaphysics and articulated novel metaphysical doctrines. Donald C. Williams was one of these philosophers. But while his contributions to metaphysics are well known his defence of metaphysics is not and yet it played a key part in the development and revival of metaphysics. In this paper I present his defence of metaphysics in (...) its historical context. I also show how his defence is relevant in response to recent attacks on metaphysics. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:154, DAVID HUME'S PRACTICAL ECONOMICS As Professor Eugene Rotwein emphasized in his introduction to David Hume: Writings on Economics (Madison, 1955), the philosopher made his observations on the eve of the industrial revolution in a period of accelerating change. Very often — as in the latter half of the seventeenth century — times of flux and turmoil call forth Utopian thinkers, who propose the creation of hierarchical, communal, authoritarian (...) societies, often patterned after a supposed golden 2 age. Hume emphatically rejected Utopian schemes of this kind. "All plans of government which suppose great reformation in the manners of mankind," he said, 3 "are plainly imaginary." He repeatedly warned as well that "projectors" and visionaries would disrupt the balance in government between liberty and authority. Thus he could speak of or make reference to "the visionary system or ravings of Plato" (in The Republic), the ultimate impracticality of More's Utopia and James Harrington's The Commonwealth of Oceana, and the absurdity of Robert Wallace's theories on 4 population and the paper money schemes of John Law. Even the Utopian republics of Andrew Fletcher of Saltoun, the Scottish patriot whom Hume admired as "a man of undaunted courage and inflexible principles," were dismissed with the others on practical grounds. The key word we have extracted from Hume's economics is practicality. Much as Hume would have liked to have designed an empirical "science of man" — which, incidentally, would have permitted him to propose his own infallible scheme of political economy — he realized that his own attempts had fallen far short of his goal. Thus his nine essays devoted especially to economics: "Of Commerce," "Of Refinement 155. in the Arts," "Of Money," "Of Interest," "Of the Balance of Trade," "Of the Jealousy of Trade," "Of Taxes," "Of Public Credit," and "Of the Populousness of Ancient Nations," are cautious in approach and pragmatic in spirit. Most of these essays were specifically designed to challenge prevailing assumptions and Utopian grand schemes of one sort or another. In "Of Commerce," for example, Hume rejects the idea that a nation can achieve greatness as an agricultural utopia. In "Of Refinement in the Arts" he takes issue with certain religious thinkers who 7 denote luxury as evil. In "Of Money" he is critical of those who believe that an injection of money into O the economy will work long-term wonders, and in "Of Interest" he argues with those who reason that the 9 plenty of money leads to low interest rates. "Of the Balance of Trade" and "Of the Jealousy of Trade" are directed against the protectionist policies of the mercantilists, "Of Taxes" rejects the French physiocratic single tax on land, and "Of Public Credit" deplores the expedients of Lord Oxford's partisans to draw bills on posterity and imprudently 12 use public credit to create paper riches. Finally, he addressed his essay, "Of the Populousness of Ancient Nations" to a refutation of the doomsday thinking of 13 the Reverend Robert Wallace of Edinburgh. This is not to imply, however, that Hume's economic thought was merely negative, or that he believed governments could safely entrust their powers over the economy to an "invisible hand." Even Hume's advocacy of free trade (which his friend and pupil Adam Smith, of course, applied with less caution) left the government with room to maneuver. Hume was willing to employ both the market and authority in designs for human progress. In seeking his mix of "action, 156. consumption, liveliness and indolence," a contradictory, counter-poised economic actor, the individual, was not a simple pleasure maximizer, nor did the acquisition of wealth and luxury make him a villain. He was a person in whom the complex springs of action, the causes of labour, needed first one, now another counter-weight. Society benefited from both 14 free trade and from tariff. Hume believed that industrial development and the advancement of commerce were the springboards to progress and happiness. Less is less and more is more; Hume never got these simple verities mixed up. "The same age," he said, "which produces great philosophers and politicians, renowned generals and poets, usually abounds with skillful weavers, and ship-carpenters.... The spirit of the age...

In lieu of an abstract, here is a brief excerpt of the content:130 HISTORY OF PHILOSOPHY To establish the chronology of the posthumous fragments of 1875-1879 in IV, 4 was of no crucial significance and presented few difficulties. The fragments of 18871888 in VIII, 2 are another matter. When Nietzsche's sister Elizabeth first published them she simply disregarded chronology in favor of a topical arrangement. Karl Schlechta proceeded more methodically. But in eliminating everything he felt Nietzsche had not intended to (...) publish, he also withdrew from scrutiny much of Nietzsche's late thinking. What to do? The editors examined the manuscripts and hit upon a new and eminently sensible arrangement. In The Genealogy of Morals Nietzsche had mentioned that he was planning a philosophical treatise entitled Will to Power. An outline of 1888 bearing the same title organized 372 of the late aphorisms both by number and key-word. Although Nietzsche in a letter to Peter Gast clearly stated that this outline was not intended for publication, the editors determined to let it serve as their guide, in the justifiable assumption that here, nonetheless, was an arrangement that was truly Nietzsche's, one that came as close as one could come to arranging the fragments as Nietzsche himself might ultimately have done. As for the remaining 100-odd fragments in the pertinent notebooks, which Nietzsche had not included in his outline, the editors decided to include them also, since their chronology was easy to establish and they were of interest despite their unpolished and incomplete form. But does not such publication do Nietzsche a real injustice as Schleehta asserted? Are not the earlier selective editions superior? Although the editors obviously don't think so, they have given the reader the opportunity to draw his own conclusions. To this end, they have compiled a concordance relating Nietzsche's outline and their own edition with the other major editions of the late fragments, showing in each case which fragments were published and in what order. The last 140 pages of VIII, 2 present unpublished fragments of the same period containing quotations and excerpts which Nietzsche had taken from his readings. Although again the principle of completeness was no doubt paramount in the decision to include these fragments, the editors feel that the excerpts from Tolstoi and Dostoyevski throw new light on the genesis of the Antichrist. It is difficult in a few paragraphs to do justice to an edition containing thousands of pages. We have said nothing about the content or the attractive and functional format. We trust, however, that our limited comments have made it clear that this edition, whether in the original German or in the Italian, French, or Japanese translations, should be in every major library and in the hands of every Nietzsche scholar. It is to be hoped that the edition will soon be completed and that translations into English and Spanish will be undertaken also. HERBERT W. REICHERT University of North Carolina Russell and Moore: The Analytical Heritage. By A. J. Ayer. (Cambridge: Harvard University Press, 1971. Pp. x+254. $8.75) It would be easy to take the view, on reading this book, that philosophical problems are never solved, people just tire of them. Ayer is at great pains to re-capture the sense of what philosophers in the earlier half of this century regarded as important issues, significant arguments and proper method. And indeed, he is so successful that one cannot help thinking from time to time that his book must have been written no later than the 1940's. Perhaps that was his intent--to relive the philosophical atmosphere BOOK REVIEWS 131 of pre-war English philosophy by recounting the views on logic and language, epistemology and metaphysics of the two major figures of that era. This is not mere recounting, nor would it be so successful a reliving if it were. Ayer offers his own counterarguments, and extensions of themes and theses propounded by Russell and Moore, but the curious thing is how of a piece these critical comments are with the expository passages. No doubt this is because Ayer is himself a relic of that age. This is not intended to be superior or sneering; in the spirit of the opening remark... (shrink)

Eleven previously published essays presenting a moderately unified argument in favor of the general conception of what Jonas calls the "Philosophy of Life," as well as detailed arguments pointing in the direction of a non-dualistic, realistic, and non-naturalistic philosophy of mind. The "nons" are deliberately placed, as Jonas spends the better part of the book questioning the tenability of dualistic and, especially, materialistic and mechanistically oriented theories of mind. With extraordinary historical sensitivity—at times threatening to dissolve a problem by laying (...) bare the conceptual confusions which surrounded its origins—and with a better than working knowledge of biology and physiology, not to mention anthropology, Jonas argues, on the one hand, that the clues to the dynamism and structure of mind are to be found in such organic features as sentience, motility, and emotion: e.g., the conceptual strands that unite in the notions of causality and truth are rooted in the respective experiences of force and resistance, and vision. On the other hand, Jonas argues for the irreducibility of the subject-object structure of man's relation to nature on the grounds that this is the necessary burden of subjectivity. In all, the book is an impressive performance.—E. A. R. (shrink)

The subject matter of this book pertains to the philosophy of science as much as to epistemology. More than three quarters of it is devoted to a discussion of Bachelard. The author takes himself to be in the tradition of Marx reading Hegel: he offers a materialist reading of idealist thinkers, leading toward his own vision of "historical materialism." Even for the English speaking reader who might be put off by the book’s ideological components, there is a fine opportunity here (...) to investigate at close-hand some recent philosophical currents in France, those set in motion by Bachelard.

The essay on abstraction provides an historical review of the notion of abstraction with an attempt being made to show that there is a basic similarity between the doctrines of Aristotle and Aquinas, on the one hand, and Locke on the other. The conclusion that is then drawn is that the nominalistic critique initiated by Berkeley and refined by Hume in direct answer to the Lockean theory of general ideas is effective against all doctrines of abstraction which hope to end (...) up in a moderate realism. Other concerns are 1) to show the basic affinities between Berkeleyean and Humean nominalism, and late medieval nominalism, in particular that of Ockham, 2) to show that such a nominalism is inadequate and must be replaced by, what has been termed in contemporary analytical circles, psychological nominalism. The essay on relation shows the continuity in the history of the doctrine of relations from the time of Melissus to the Rusellian critique of the substance-accident ontology, critique which Weinberg thinks definitively replaced the unilateral-attribute doctrine of relations. The essay on induction attempts to show how the medieval commentators modified Aristotle's intuitionistic and vestigally [[sic]] Platonic doctrine of induction into a doctrine of covert inference, and anticipated, in part, Bacon's and Mill's theories.—E. A. R. (shrink)

This addition to Herder's "Quaestiones Disputatae" Series is a portion of Rahner's and Overhage's Das Problem der Hominisation; it is very nicely self-contained. After a rapid review of what the ecclesiastical and scriptural sources have to say about the problem of human origins and evolution as a possible explanation of these origins, Rahner launches into a metaphysical analysis of the concepts of "spirit" and "matter," on the one hand, and "causality" and "becoming," on the other. The method is transcendental and (...) the epistemology is that of a critical realism like that of Maréchal and Lonergan. The major innovation comes in Rahner's interpretation of Aristotelian efficient causality. Taking noetic transcendence, i.e., intentional becoming, as the paradigm for all becoming—anything less being a deficient form of the activity of being as spirit—Rahner argues in favor of a cause transcending itself in the production of an effect, whether immanent or transitive. Thus Rahner sees no essential contradiction between the traditional notion of causality, so interpreted, and a theory of biological and human emergence. The going is always rough through Rahner, but the speculative asides he scatters throughout this book on such questions as the unity of the biosphere and sub-organic telism are enough in themselves to justify the trip.—E.

Fifteen essays by as many contributors with a summative introduction by Edie. The contributors are Dreyfus, Adamczewski, Earle, Compton, J. E. Smith, J. M. Anderson, Natanson, Silber, Crosson, Molina, G. E. Myers, Tillman, W. J. Richardson, Langan, and Findlay. All of the essays were presented in one form or another at one of the last three meetings of the Society for Phenomenology and Existential Philosophy. Some of them have been considerably reworked and expanded, the most important of which is John (...) Silber's fifty-seven page paper, "Being and Doing." Silber subjects the contemporary analytical version of voluntary responsibility, as found paradigmaticaliy in H. L. A. Hart's work, to a severe critique, arguing that a notion of status responsibility which involves following intentions and motives back to their pre-thematic roots in attitudes and a whole style of life, or way of being, is more consonant with human experience and nature than the antiseptic notion of responsibility developed by Hart. Even Hampshire takes his lumps at Silber's hands. Other excellent papers include Findlay's "Essential Probabilities," which can be read as a plea for a material logic, and Richardson's "Kant and the Late Heidegger," which uses Heidegger's reflection on the Kantian problematic to examine the issue of the continuity between the early and the later Heidegger. Not all of the essays approach the standards of these three, but for a collection of papers that have only the meeting of the same society in common, this is better than most.—E. A. R. (shrink)

In what is at the very least a tour de force, one of the most important contemporary Italian philosophers, Michele Sciacca, has given a critical exposition of literally hundreds of philosophical writers who share in common the tradition of Western philosophy from Kant and Hegel back through Descartes, on the one hand, and back through Augustine, Aristotle, and Plato, on the other. Treatment ranges from a paragraph or two to nineteen pages in the case of Kierkegaard. For those not sharing (...) Sciacca's preference for an integral Christian philosophy which can successfully incorporate all the positive values of humanism, his "criticisms" will frequently seem polemical and unsupported by the exposition he has provided. This is particularly the case in his treatment of scientifically oriented, analytical and linguistic philosophy which he discusses in a chapter with the somewhat unflattering title, "'Physicalism' and the New 'Scientific' Barbarity." But the book is obviously intended more as an act of philosophical reflection than as a history of contemporary philosophy, and is, in this respect, to be assessed more by the criterion of philosophical soundness used to judge, e.g., Aristotle's handling of his predecessors, and Hegel's reading of the history of philosophy, than by considerations of historical scholarship. And, as philosophy, Sciacca's Christian Spiritualism is imposing.—E. A. R. (shrink)

Published as one of the issues of the quarterly periodical Continuum, this is one of those rare Festschriften which is given over to the Schriften of the man whose Fest it is. In this way, the essays represents the solidest, first-hand coming to grips with the systematic and expansive thought of a first-rate philosopher and theologian. Of particular interest is the contribution by E. M. McKinnon, "Cognitional Analysis and the Philosophy of Science," in which Lonergan's philosophy of science is shown (...) to have deep affinities with the Scientific Realism espoused by many contemporary analytical philosophers. Lonergan himself provides a whirlwind and breathtaking synoptic review of his past work in the final essay of the volume, in which he begins à la Hegel in sense certainty and ends with authentic human existence as the integration of objective knowing and dynamic intersubjectivity. A bibliography of Lonergan's writings is included.—E. A. R. (shrink)

James Collins has turned his talent for painstaking and definitive scholarship to the philosophy of religion, and nobody with an interest in this particular area of philosophy, or in the general development of modern philosophy in the hands of Hume, Kant, and Hegel, can afford to miss consulting this book. The philosophy of religion, as distinct from the older style natural theology, theodicy, and straight theological treatments of religion, is a discipline whose need was first felt when the scientific (...) picture of the universe began to declare its independence from, and possible ascendency over, the theistically ordered anthropological and cosmological harmony of the universe. As Collins details in a balanced manner, it was Hume who first formulated a program to meet this need. He did it in such a way, however, that he made religion a legitimate object of, but wholly external and even inimical in content to, philosophy, particularly epistemology and ethics. Building upon Hume, Kant defined the epistemological issue more precisely—"I have denied knowledge to save belief"—and reinterpreted the relation between morality and religion as one of complementarity rather than contradictoriness. It remained for Hegel to internalize the relation between the content of religion and the content of philosophy and thus to reduce the former to an anticipation of the latter. Collins' exposition is interpenetrated by a critical concern supplied by the dialectical development of the idea of the philosophy of religion from Hume through Kant to Hegel, and by his own proposal for integrating the genuine and irreducible insights of each of these three classical philosophies within a realistic philosophy of religion that remains basically theistic. The book is an expanded form of Collins' St. Thomas More Lectures at Yale University; it would be an impressive addition to any series of lectures.—E. A. R. (shrink)

Start with descriptive sketches of the epistemologies and ontological underpinnings of the philosophies of Plato, Aristotle, Descartes, Hume, and Kant, as they form the point of departure for the modern reductionistic and mechanistic paradigm of scientific explanation—the thesis is modified in the case of Kant, a transitional figure, who did emphasize the notion of agency, but still as fitted into the Cartesian, dualistic framework—and as they provide the locus of return, with important modifications, to teleological, emergentistic, and holistic frameworks of (...) explanation. Add a pluralistic ontology of "comprehensive entities," which relies heavily on M. Polanyi's conceptions of "personal knowledge," "tacit knowing," and the "unexpected-range-of-possibilities" criterion for assessing degrees of reality of grades of being. Blend the former two ingredients with clear and cogent argumentation as well as a skillful handling of some of the recent sources in biology as they bear on the problem of deciding whether emergence and telism are irreducible features of even a rationally reconstructed framework of experience, and one has the makings of a challenging book by Marjorie Grene. Grene is anything but heavy-handed in her treatment of the devil of reductionism which she has located; but it is doubtful that she has given him his full due—insofar as she has concentrated her fire on an older style of behaviorism and mechanism that itself often has difficulty recognizing its rapidly matured and much more sophisticated progeny, scientific realism.—E.

What is the future of Philosophy of education? Or as many of scholars and thinkers in this final ‘future-focused’ collective piece from the philosophy of education in a new key Series put it, what are the futures—plural and multiple—of the intersections of ‘philosophy’ and ‘education?’ What is ‘Philosophy’; and what is ‘Education’, and what role may ‘enquiry’ play? Is the future of education and philosophy embracing—or at least taking seriously—and thinking with Indigenous ethicoontoepistemologies? And, perhaps most importantly, what is that (...) ‘Future’? These debates have been located in the work of diverse scholars: from the West, from Global South, from indigenous thinkers. In this collective piece, we purposefully juxtapose diverse takes on the future of these intersections. We have given up the urge to organise, place together, separate with subheadings or connect the paragraphs that follow. Instead, we let these philosophers of education and thinkers who use philosophical texts and ideas to sit together in one long read as potentially ‘strange and unusual bedfellows’. This text urges us to understand how these scholars and thinkers perceive our educational philosophical futures, and how the work and thinking they have done on thinking about what the future of that new key in philosophy of education may look like is embedded in a much deeper and richer literature, and personal experience.

Epistemic decision theorists aim to justify Bayesian norms by arguing that these norms further the goal of epistemic accuracy—having beliefs that are as close as possible to the truth. The standard defense of Probabilism appeals to accuracy dominance: for every belief state that violates the probability calculus, there is some probabilistic belief state that is more accurate, come what may. The standard defense of Conditionalization, on the other hand, appeals to expected accuracy: before the evidence is in, one should expect (...) to do better by conditionalizing than by following any other rule. We present a new argument for Conditionalization that appeals to accuracy‐dominance, rather than expected accuracy. Our argument suggests that Conditionalization is a rule of coherence: plans that conflict with Conditionalization don't just prescribe bad responses to the evidence; they also give rise to inconsistent attitudes.

1. The “puzzle” Physical objects are coloured: roses are red, violets are blue, and so forth. In particular, physical objects have fine-grained shades of colour: a certain chip, we can suppose, is true blue (unique, or pure blue). The following sort of scenario is commonplace. The chip looks true blue to John; in the same (ordinary) viewing conditions it looks (slightly) greenish-blue to Jane. Both John and Jane are “normal” perceivers. Now, nothing can be both true blue and greenish-blue; since (...) the chip is true blue, it is not greenish-blue. Hence Jane, unlike John, is misperceiving the chip. Generalizing, the conclusion is that there is widespread misperception of fine-grained shades. According to Tye (2006), and Cohen, Hardin, and McLaughlin (2006), the previous paragraph amounts to a paradox: an apparently unacceptable conclusion has been drawn from apparently acceptable premises via apparently acceptable reasoning. (See also Hawthorne and Kovakovich 2006, 180-1.) Tye swallows the conclusion, aided by a dose of evolutionary speculation. Hardin (1988), on the other hand, rejects the first premise, and denies that physical objects are coloured. Cohen (2004) and McLaughlin (2003) claim that both Jane and John have the colour of the chip right. Our opening paragraph concealed a crucial parameter. In fact, the chip looks greenish-blue-relative-to- circumstances-C to Jane, and true-blue-relative-to-circumstances-C* to John, and the chip has both these relativized colours.1 All this ingenious philosophizing would be in vain, of course, if the conclusion of the opening paragraph were not puzzling or problematic. So, why is it supposed to be? According to Tye, the conclusion is puzzling because John and Jane are both “normal perceivers” (xx). He seems to think that it is (prima facie) plausible to assume..

We investigate the complexity of various combinatorial theorems about linear and partial orders, from the points of view of computability theory and reverse mathematics. We focus in particular on the principles ADS (Ascending or Descending Sequence), which states that every infinite linear order has either an infinite descending sequence or an infinite ascending sequence, and CAC (Chain-AntiChain), which states that every infinite partial order has either an infinite chain or an infinite antichain. It is well-known that Ramsey's Theorem for pairs (...) (RT₂²) splits into a stable version (SRT₂²) and a cohesive principle (COH). We show that the same is true of ADS and CAC, and that in their cases the stable versions are strictly weaker than the full ones (which is not known to be the case for RT₂² and SRT₂²). We also analyze the relationships between these principles and other systems and principles previously studied by reverse mathematics, such as WKL₀, DNR, and BΣ₂. We show, for instance, that WKL₀ is incomparable with all of the systems we study. We also prove computability-theoretic and conservation results for them. Among these results are a strengthening of the fact, proved by Cholak, Jockusch, and Slaman, that COH is Π₁¹-conservative over the base system RCA₀. We also prove that CAC does not imply DNR which, combined with a recent result of Hirschfeldt, Jockusch, Kjos-Hanssen, Lempp, and Slaman, shows that CAC does not imply SRT₂² (and so does not imply RT₂²). This answers a question of Cholak, Jockusch, and Slaman. Our proofs suggest that the essential distinction between ADS and CAC on the one hand and RT₂² on the other is that the colorings needed for our analysis are in some way transitive. We formalize this intuition as the notions of transitive and semitransitive colorings and show that the existence of homogeneous sets for such colorings is equivalent to ADS and CAC, respectively. We finish with several open questions. (shrink)

Taking as its starting point Miri Gur-Arye’s critical discussion of a legal duty to report crime, this paper sketches an idealising conception of a democratic republic whose citizens could be expected to recognise a civic responsibility to report crime, in order to assist the enterprise of a criminal law that is their common law. After explaining why they should recognise such a responsibility, what its scope should be, and how it should be exercised, and noting that that civic responsibility must (...) include a responsibility to report one’s own crimes; it discusses whether that civic responsibility could ground at least a limited legal duty to report certain types of crime. It then turns to the question of whether a civic responsibility to assist the criminal law’s enterprise of bringing wrongdoers to account could include a responsibility to arrest suspected or known offenders if the police cannot or will not do so—a responsibility to make a citizen’s arrest, and the legal power to discharge that responsibility: how far should citizens feel entitled, or duty-bound, thus to ‘take the law into their own hands’?

Freud seems to have been torn between a literary and a scientific model for his enterprises. On the one hand he stresses the scientific nature of his researches to an extent which makes the suspicious reader wonder whether he protests too much. On the other hand it is well known that he regarded many writers, though predominantly Shakespeare, as anticipating his findings on the unconscious. In one famous passage in the Introductory Lectures on Psycho-analysis he places his discovery of the (...) unconscious on a par with the discoveries of Darwin and Copernicus in their effect upon man's picture of himself. He is justified, of course, and if we add Marx to this triumvirate we add a figure even closer to Freud in claiming a scientific status for his work, a scientific status which is, to the uncommitted, dubious. Theodore Mischel argues that Freud increasingly construes neurotic behaviour upon the model of ordinary intentional behaviour and, though he continued to show interest in the view that the unconscious impulses which are repressed are physiological in nature, this ideal of a reduction of the psychological to the physiological became a less active ingredient in his published work as his collaboration with Fliess receded into the past. So although he may have paid lip service to some form of psycho-physical identity, believing that mental phenomena are ultimately no more or less than physical happenings in the neurones of the brain, in mature Freud this seems to have been an idly spinning wheel. Roy Schafer has recently pointed out that many of Freud's followers use the concepts of natural science , whilst simultaneously retaining traces of anthropomorphism in their metapsychology. For instance Heinz Hartmann emphasizes the concept of a ‘higher organizing function’ which resists formulation in the mechanistic metapsychology he favours. Similar difficulties obtrude in the work of Waelder and Kohut. The significance of these conflicts leads Schafer to frame basic Freudian insights in terms of the theory of action, stressing the manner in which an action may be described in differing ways and thus allowing us to present the fact that a patient's behaviour may both tell and not tell us of his deepest anxieties. Yet curiously Schafer denies that freedom plays any part in his account whereas we would have expected a concept so central to agency to have an equally central role in any recasting of psycho-analysis in terms of the theory of action.

A deep investigation of proprioceptive processes is necessary to understand the relationship between sensory afferent inputs and motor outcomes. In this work, we investigate whether and how perception of wrist position is influenced by the direction along which the movement occurs. Most previous studies have tested Joint Position Sense through 1 degree of freedom wrist movements, such as flexion/extension or radial/ulnar deviation. However, the wrist joint has 3-DoF and many activities of daily living produce combined movements, requiring at least 2-DoF (...) wrist coordination. For this reason, in this study, target positions involved movement directions that combined wrist flexion or extension with radial or ulnar deviation. The chosen task was a robot-aided Joint Position Matching, in which blindfolded participants actively reproduced a previously passively assumed target joint configuration. The JPM performance of 20 healthy participants was quantified through measures of accuracy and precision, in terms of both perceived target direction and distance along each direction of movement. Twelve different directions of movement were selected and both hands tested. The left and right hand led to comparable results, both target extents and directions were differently perceived according to the target direction on the FE/RUD space. Moreover, during 2-DoF combined movements, subjects’ perception of directions was impaired when compared to 1-DoF target movements. In summary, our results showed that human perception of wrist position on the FE/RUD space is symmetric between hands but not isotropic among movement directions. (shrink)

_Purpose._ This article reveals the importance of the analysis of the theory of generations to identify the essential characteristics of the phenomenon of youth. _Theoretical basis_ of this study is socio-philosophical anthropology, i.e. philosophical anthropology using certain methods of sociological, socio-psychological and ethnological research, as well as philosophical comprehension of the application of these methods in special sciences. _Originality._ The authors rethought the theoretical and practical potential of generational theory through its reconceptualization based on philosophical anthropology, which created an opportunity (...) to shift research attention from the attempts to identify superhistorical characteristics of youth to the identification of the essential nature of specific historical and sociocultural features of young people as representatives of a particular culture. _Conclusions._ Defining the youth phenomenon requires accounting at least three constraints that on the one hand, play a role of warnings that deter from theoretical and practical errors in the study of the youth phenomenon, and on the other hand, guidelines for identifying real, specific characteristics of youth as a social phenomenon. Limitations of theoretical and practical analysis of young people are as follows: first, the need to consider demographic data not as final, but only as initial and preliminary, such that require further substantive socio-cultural analysis; second, the inadmissibility of ignoring the cultural diversity of the manifestations of the youth phenomenon, instead the need to identify the special characteristics of youth of different ethnic, religious and other groups; third, the need to take into account the specifics of self-identification of those who identify themselves as young people as a social group.

“Tell me," Wittgenstein once asked a friend, "why do people always say, it was natural for man to assume that the sun went round the earth rather than that the earth was rotating?" His friend replied, "Well, obviously because it just looks as though the Sun is going round the Earth." Wittgenstein replied, "Well, what would it have looked like if it had looked as though the Earth was rotating?” What would it have looked like if we looked at all (...) sciences from the viewpoint of Wittgenstein’s philosophy? Wittgenstein is undoubtedly one of the most influential philosophers of the twentieth century. His complex body of work has been analysed by numerous scholars, from mathematicians and physicists, to philosophers, linguists, and beyond. This volume brings together some of his central perspectives as applied to the modern sciences and studies the influence they may have on the thought processes underlying science and on the world view it engenders. The contributions stem from leading scholars in philosophy, mathematics, physics, economics, psychology and human sciences; all of them have written in an accessible style that demands little specialist knowledge, whilst clearly portraying and discussing the deep issues at hand.

The browser wars case is a useful springboard for considering the principle of positive competition and the proper regulation of platform technologies. There are lessons to be culled about policy, the application of antitrust law, and the parameters of fair competition. We argue that despite Microsofts opportunistic exploitation of its proprietary code, policy makers should resist the temptation to mandate an open source code model. Vigilant anti-trust enforcement is a preferable alternative. But courts must refrain from using antitrust law to (...) favor small innovators or to constrain the economic protections inherent in intellectual property rights, since those rights are still needed to encourage innovation. On the other hand, despite the exigencies of competition, platform leaders should respect the norm of fair competition and refrain from the impulse to tilt the platform in their favor.

According to its supporters open source software is more secure and reliable than proprietary code, and even tends to foster more innovation. Its technical superiority can be linked to the ongoing peer review process which typifies the open source model. In addition, programs such as Linux offer a potential challenge to the hegemony of Microsoft. Open source holds out the possibility of restraining platform leaders such as Microsoft from acting opportunistically. Some even argue that the open source code model is (...) ethically superior to the proprietary model because of its transparency. Given these economic and social benefits, should government policy makers intervene, by tilting the playing field to open source programs? Would such government intervention truly be welfare‐enhancing? Before answering that question we note that some of the presumed technical and economic benefits of open source software are open to question. At the same time, the claims of moral superiority or social desirability are inflated and discount incentives necessary for software development. But even if this software were technically and morally superior, there is still no basis for government intervention. Our position is simple: the invisible hand of the market and not the visible hand of government should decide the fate of open source code. There is no identifiable market failure for the government to fix nor is there any plausible policy justification for giving open source software preferential treatment. (shrink)

For the philosopher Ivan Illich, society became a set of systems rather than a group of people. As such, society depersonalizes life and brings the need for open non-systematized spaces where people can act and interact outside their typical roles. On the other hand, an absence of formal structures may simply open spaces for the informal reproduction of society’s already well-established structures. Given this conjuncture, can systems be designed to foster personal expression? The answer I found in cybernetics is self-organization, (...) a process of adaptation to a context that can grow different organizations depending on what this context provides. This implies that personal expression is a concern in society’s emergent organizations, calling for meta planning to design the context of some of society’s self-organization processes. The cybernetician Gordon Pask argued that depersonalization follows from non-conversational communications, like the ones that develop in large committees. In response, Pask’s fellow cybernetician Stafford Beer proposed a meeting protocol called Team Syntegrity allowing large groups to subdivide into small integrated discussion groups. While Beer’s work has been extensively discussed in existent literature, this article presents the results of four experiments conducted by using variations of Beer’s protocol to understand both the ease with which it can be adapted to different situations, and the implications of its conversational structure on personal expression. The experiment’s realization demonstrates that the protocol’s preparation is laborious and hard to adapt in a timely manner in situations where participant numbers fluctuate. Automation of these processes, however, offers possibilities to use the approach in loosely organized groups. Automation can also help choosing the most appropriate protocol for particular situations through the manipulation of its configuration. Despite difficulties, the protocol offers promise for different purposes, encouraging personal expression in a way that reverberates with others’ personal perspectives. (shrink)

It is assumed that social bonds in humans have consequences for virtually all aspects of behavior. Social touch-based contact, particularly hand caressing, plays an important role in social bonding. Pre-programmed neural circuits likely support actions (or predispositions to act) towards caressing contacts. We searched for pre-set motor substrates towards caressing by exposing volunteers to bonding cues and having them gently stroke a very soft cloth, a caress-like movement. The bonding cues were pictures with interacting dyads and the control pictures presented (...) non-interacting dyads. We focused on the readiness potential, an electroencephalographic marker of motor preparation that precedes movement execution. The amplitude of the readiness potential preceding the grasping of pleasant emotional-laden stimuli was previously shown to be reduced compared with neutral ones. Fingers flexor electromyography measured action output. The rationale here is that stroking the soft cloth when previously exposed to bonding cues, a compatible context, would result in smaller amplitudes of readiness potentials, as compared to the context with no such cues. Exposure to the bonding pictures increased subjective feelings of sociability and decreased feelings of isolation. Participants who more frequently engage in mutual caress/groom a “significant other” in daily life initiated the motor preparation earlier, reinforcing the caress-like nature of the task. As hypothesized, readiness potentials preceding the caressing of the soft cloth were significantly reduced under exposure to bonding as compared to control pictures. Furthermore, an increased fingers flexor electromyographic activity was identified under exposure to the former as compared to the latter pictures. The facilitatory effects are likely due to the recruitment of pre-set cortical motor repertoires related to caress-like movements, emphasizing the distinctiveness of neural signatures for caress-like movements.

BackgroundThe outbreak of novel coronavirus disease 2019 has caused a global panic and public concern due to its mortality ratio and lack of treatments/vaccines. Reduced levels of physical activity have been reported during the outbreak, affecting the normal daily pattern.ObjectiveTo investigate the relationship of physical activity level with sleep quality and the effects of reduction physical activity levels on sleep quality.MethodsA Google form was used to address personal information, COVID-19 personal care, physical activity, and mental health of 1,907 adult volunteers. (...) Binary logistic regression was used to verify the association of physical activity parameters and sleep quality.ResultsInsufficient physical activity levels were a risk factor to have disturbed sleep pattern [OR: 1.28, 95% CI ]; however, when the BMI was added to the analysis, there was no more statistical difference [OR: 1.23, 95% CI ]. On the other hand, we found that the reduction of physical activity levels was associated with negative changes in sleep quality [OR: 1.73, 95% CI ], regardless all the confounders [OR: 1.30, 95% CI ], unless when feeling of depression was added in Model 6 [OR: 1.28, 95% CI ].ConclusionDisruption in daily physical activity routine, rather than physical activity level, negatively influences sleep quality during the COVID-19 quarantine.

Older adults prefer positive over negative information in a lab setting, compared to young adults. The extent to which OA avoid negative events or information relevant for their health and safety is not clear. We first investigated age differences in preferences for fear-enhancing vs. fear-reducing news articles during the Ebola Outbreak of 2014. We were able to collect data from 15 YA and 13 OA during this acute health event. Compared to YA, OA were more likely to read the fear-enhancing (...) article, select hand-sanitizer over lip balm, and reported greater fear of Ebola. We further investigated our research question during the COVID-19 pandemic with 164 YA and 171 OA. Participants responded to an online survey about the COVID-19 pandemic across 13 days during the initial peak of the pandemic in the United States. Both YA and OA preferred to read positive over negative news about the coronavirus, but OA were even more likely than YA to prefer the positive news article. No age differences in the fear of contraction were found, but OA engaged in more health-protective behaviors compared to YA. Although OA may not always report greater fear than YA or seek out negative information related to a health concern, they still engage in protective health behaviors. Thus, although positivity effects were observed in attention and emotional reports, OA still modified their behaviors more than YA, suggesting that positivity effects did not hamper OA ability to respond to a health crisis.

ABSTRACTRumination has long been considered a verbal thought process, though emerging evidence suggests that some individuals dwell on maladaptive imagery. This series of studies evaluated imagery and verbal thought during experimentally induced rumination and distraction. In Study 1, imagery and verbal thought during rumination resulted in similar increases in negative affect. Greater imagery during distraction, on the other hand, was associated with greater decreases in negative affect while verbal thought was not related to affect change. Given that greater verbal thought (...) was reported in the rumination condition and greater imagery was reported in the distraction condition, Study 2 evaluated whether the rumination/distraction induction was confounded by concurrent induction of imagery or verbal thought. The rumination prompts induced both rumination and verbal thought and the distraction prompts induced both distraction and imagery. Using a revised induction, Study 3 tested whether imagery and verbal t... (shrink)

In this basically expository paper we discuss the role of logic and mathematics in researches concerning the ontology of scientific theories, and we consider the particular case of quantum mechanics. We argue that systems of logic in general, and classical logic in particular, may contribute substantially with the ontology of any theory that has this logic in its base. In the case of quantum mechanics, however, from the point of view of philosophical discussions concerning identity and individuality, those contributions may (...) not be welcome for a specific interpretation, and an alternative system of logic perhaps could be used instead of a classical system. In this sense, we argue that the logic and ontology of a scientific theory may be seen as mutually influencing each other. On the one hand, logic contributes to shape the general features of the ontology of a theory; on the other hand, the theory also puts constraints on the possible understanding of ontology and, respectively, on possible systems of logic that may be the underlying logic of the theory.

Watching another person in pain activates brain areas involved in the sensation of our own pain. Importantly, this neural mirroring is not constant; rather, it is modulated by our beliefs about their intentions, circumstances, and group allegiances. We investigated if the neural empathic response is modulated by minimally-differentiating information (e.g., a simple text label indicating another’s religious belief), and if neural activity changes predict ingroups and outgroups across independent paradigms. We found that the empathic response was larger when participants viewed (...) a painful event occurring to a hand labeled with their own religion (ingroup) than to a hand labeled with a different religion (outgroup). Counterintuitively, the magnitude of this bias correlated positively with the magnitude of participants’ self-reported empathy. A multivariate classifier, using mean activity in empathy-related brain regions as features, discriminated ingroup from outgroup with 72% accuracy; the classifier’s confidence correlated with belief certainty. This classifier generalized successfully to validation experiments in which the ingroup condition was based on an arbitrary group assignment. Empathy networks thus allow for the classification of long-held, newly-modified and arbitrarily-formed ingroups and outgroups. This is the first report of a single machine learning model on neural activation that generalizes to multiple representations of ingroup and outgroup. The current findings may prove useful as an objective diagnostic tool to measure the magnitude of one’s group affiliations, and the effectiveness of interventions to reduce ingroup biases. (shrink)

Recently, there has been renewed interest in the search for low-mass magnetic monopoles. At the University of Oklahoma we are performing an experiment (Fermilab E882) using material from the old D0 and CDF detectors to set limits on the existence of Dirac monopoles of masses of the order of 500 GeV. To set such limits, estimates must be made of the production rate of such monopoles at the Tevatron collider, and of the binding strength of any such produced monopoles to (...) matter. Here we sketch the still primitive theory of such interactions, and indicate why we believe a credible limit may still be obtained. On the other hand, there have been proposals that the classic Euler–Heisenberg Lagrangian together with duality could be employed to set limits on magnetic monopoles having masses less than 1 TeV, based on virtual, rather than real processes. The D0 collaboration at Fermilab has used such a proposal to set mass limits based on the nonobservation of pairs of photons each with high transverse momentum. We critique the underlying theory, by showing that the cross section violates unitarity at the quoted limits and is unstable with respect to radiative corrections. We therefore believe that no significant limit can be obtained from the current experiments, based on virtual monopole processes. (shrink)

The principle of respect for human dignity plays a crucial role in the emerging global norms relating to bioethics, in particular in the UNESCO Universal Declaration on Bioethics and Human Rights. This instrument, which is a legal, not merely an ethical document, can be regarded as an extension of international human rights law into the field of biomedicine. Although the Declaration does not explicitly define human dignity, it would be a mistake to see the emphasis put on this notion as (...) a mere rhetorical strategy. Rather, the appeal to dignity reflects a real concern about the need to promote respect both for the intrinsic worth of human beings and for the integrity of the human species. But dignity alone cannot solve most of the dilemmas posed by biomedical practice. This is why international biolaw combines, on the one hand, the appeal to human dignity as an overarching principle with, on the other hand, the recourse to human rights, which provide an effective and practical way forward for dealing with bioethical issues at a global level.

Background: The traditional approach to resolving ethics concerns may not address underlying organisational issues involved in the evolution of these concerns. This represents a missed opportunity to improve quality of care “upstream”. The purpose of this study was to understand better which organisational issues may contribute to ethics concerns. Methods: Directed content analysis was used to review ethics consultation notes from an academic children’s hospital from 1996 to 2006 (N = 71). The analysis utilised 18 categories of organisational issues derived (...) and modified from published quality improvement protocols. Results: Organisational issues were identified in 68 of the 71 (96%) ethics consult notes across a range of patient settings and reasons for consultation. Thirteen of the 18 categories of organisational issues were identified and there was a median of two organisational issues per consult note. The most frequently identified organisational issues were informal organisational culture (eg, collective practices and approaches to situations with ethical dimensions that are not guided by policy), policies and procedures (eg, staff knows policy and/or procedural guidelines for an ethical concern but do not follow it) and communication (eg, communication about critical information, orders, or hand-offs repeatedly does not occur among services). Conclusions: Organisational issues contribute to ethical concerns that result in clinical ethics consults. Identifying and addressing organisational issues such as informal culture and communication may help decrease the recurrence of future similar ethics concerns. (shrink)

We are highly tuned to each other's visual attention. Perceiving the eye or hand movements of another person can influence the timing of a saccade or the reach of our own. However, the explanation for such spatial orienting in interpersonal contexts remains disputed. Is it due to the social appearance of the cue—a hand or an eye—or due to its social relevance—a cue that is connected to another person with attentional and intentional states? We developed an interpersonal version of the (...) Posner spatial cueing paradigm. Participants saw a cue and detected a target at the same or a different location, while interacting with an unseen partner. Participants were led to believe that the cue was either connected to the gaze location of their partner or was generated randomly by a computer (Experiment 1), and that their partner had higher or lower social rank while engaged in the same or a different task (Experiment 2). We found that spatial cue‐target compatibility effects were greater when the cue related to a partner's gaze. This effect was amplified by the partner's social rank, but only when participants believed their partner was engaged in the same task. Taken together, this is strong evidence in support of the idea that spatial orienting is interpersonally attuned to the social relevance of the cue—whether the cue is connected to another person, who this person is, and what this person is doing—and does not exclusively rely on the social appearance of the cue. Visual attention is not only guided by the physical salience of one's environment but also by the mental representation of its social relevance. (shrink)

R.S. Peters' arguments for the worthwhileness of theoretical activities are intended to justify education per se, on the assumption that education is necessarily a matter of initiating people into theoretical activities. If we give up this assumption, we can ask whether Peters' arguments might serve instead to justify the academic curriculum over other curricular arrangements. For this they would need to show that theoretical activities are not only worthwhile but, in some relevant sense, more worthwhile than activities of other kinds. (...) I argue that Peters' hedonistic and transcendental arguments do not show this, but that his account of theoretical activities is suggestive of an instrumental argument which might fit the bill.

Living organ donation in the UKThe prospect of new regulation is often met with reluctance and legitimate fears of additional bureaucracy for very little benefit. Changes to the approval procedure for living organ donation in the UK, however, appear to have made a real, and positive, difference to the practice. The Human Tissue Act 2004 abolished the Unrelated Live Transplants Regulatory Authority and handed responsibility for overseeing living donation to the newly established Human Tissue Authority. On paper, the new system (...) appeared to be a significant improvement on the old one. It removed the illogical disparity between related and unrelated donors. Previously only donations from unrelated individuals needed prior approval and evidence of a genetic link was a green light to proceed without further investigation, suggesting, erroneously, that donation within families was always voluntary and free from pressure and coercion. While the reasoning behind this distinction was obvious—coming as it did in the immediate aftermath of the uncovering of an international trade in human organs—the logic behind the distinction was lacking. Although the list of permitted relationships was broad, donation between spouses, long-term partners or friends was subject to the full and frequently drawn-out approval process designed to prevent surreptitious payment.Now all living organ donation needs prior approval but the system has been streamlined to avoid the long delays that became synonymous with the old system. Under the new regime: Applications are reviewed at a local level by a group of “independent assessors” who have been trained and accredited by the HTA.The independent assessor must be satisfied that the person consenting to the donation has been given and understood the necessary information and that there is no evidence of reward or coercion or evidence that the person has been subjected to pressure to consent. ….

The ethics of belief involves an inquiry into what beliefs are legitimate to hold, including religious beliefs. Whatever the criteria determined in such an investigation, adopting a belief that does not meet this criterion is seen as illegitimate and it is considered an ethical violation. English mathematician W. K. Clifford (d. 1879) defines “sufficient evidence” as a criterion in his famous essay, “The Ethics of Belief”. Clifford’s evidence-centered argument becomes one of the most frequent references in the evidentialist objection against (...) theism. It turns out that this argument is not functional in the face of the diversity of beliefs. In this context, different suggestions are presented about what the ethics of belief could be. American philosopher William James (d. 1810), one of the founding names of pragmatism, offers a new proposal. In his classic work, “The Will to Believe”, James claims that Clifford is wrong in seeking the requirement of evidence for all beliefs. Because it is not possible to prove beliefs from the passionate nature of human beings, especially religious beliefs. Following this distinction, James proposes a new criterion for religious beliefs: a religious belief can be vivid or dead, forced or avoidable; and momentous or trivial. If a religious belief is vivid, forced, and momentous, it is necessary to have the courage to believe in it instead of suspending it. James' proposal is often valued as a strong counter-challenge or defense of religious beliefs. However, this argument also has aspects that are open to criticism. One of them is that the will to believe argument concurrently accepts conflicting religious beliefs or, in other words, confronts the issue of religious diversity. According to J. Hick, for example, this argument inevitably results in religious pluralism, even though James does not want to. Contrary to Hick, S. F. Aikin claims that the will to believe does not result in religious pluralism. According to Aikin, who draws attention to the relationship of argument with pragmatism, James obscures religious beliefs and removes them from being claims about truth. Therefore, there is no contradiction in the classical sense. So, which of the objections is valid? Does the will-to-believe argument result in religious pluralism by legitimizing more than one religious belief at the same time, or does it make a purely pragmatic proposition by devaluing religious beliefs? Which religion do I have the right to believe in according to the will to believe? The aim of this article is to provide an answer to the mentioned question. In the article, unlike the current evaluations, it is argued that the argument is closely related to James's theory of knowledge, radical empiricism, not pragmatism as it is usually made. For this purpose, after showing the relationship between the arguments of Clifford and James, the argument will be re-examined in this context and it will be revealed that James has two steps regarding religious beliefs: to make religious beliefs independent from factual beliefs; leaving theism to accept a monistic vision of God and basing religion on mystical experience, which is an emotional experience. As details emerge, it will become clear that James defends a natural religion that excludes traditional religions in his philosophical system and that he defends the beliefs of a humanized religion. With an individual definition of religion based on emotion, James on the one hand ensures the commonality of religious feeling, on the other hand, he makes religion independent from the field of facts. Therefore, with this study, it will be seen that the argument of the will to believe does not aim to legitimize believing in traditional religions, and diversity is not a fundamental problem.

As a counter-argument to Moore's "Refutation of Idealism," this article explains how the application of non-dualistic idealism reveals the underlying problem in both narrowly defined "esse is principi" brands of idealism and Moore's realism. The issue at hand, this article suggests, is the presupposition that experience naturally forks off into subjective consciousness and particular objects of consciousness. Rather than agree with either Moore or dualistic forms of idealism, the Vedanta-inspired view set forth in this article provides a third option to (...) reject the ontological commitments of the former two philosophical stances. This third stance suggests that reality amounts to consciousness, and, thus, motivates the conclusion that modes of consciousness are what differentiate experience, not the bifurcation of experience into subject and object.

Physical Relativity explores the nature of the distinction at the heart of Einstein's 1905 formulation of his special theory of relativity: that between kinematics and dynamics. Einstein himself became increasingly uncomfortable with this distinction, and with the limitations of what he called the 'principle theory' approach inspired by the logic of thermodynamics. A handful of physicists and philosophers have over the last century likewise expressed doubts about Einstein's treatment of the relativistic behaviour of rigid bodies and clocks in motion in (...) the kinematical part of his great paper, and suggested that the dynamical understanding of length contraction and time dilation intimated by the immediate precursors of Einstein is more fundamental. Harvey Brown both examines and extends these arguments, after giving a careful analysis of key features of the pre-history of relativity theory. He argues furthermore that the geometrization of the theory by Minkowski in 1908 brought illumination, but not a causal explanation of relativistic effects. Finally, Brown tries to show that the dynamical interpretation of special relativity defended in the book is consistent with the role this theory must play as a limiting case of Einstein's 1915 theory of gravity: the general theory of relativity.Appearing in the centennial year of Einstein's celebrated paper on special relativity, Physical Relativity is an unusual, critical examination of the way Einstein formulated his theory. It also examines in detail certain specific historical and conceptual issues that have long given rise to debate in both special and general relativity theory, such as the conventionality of simultaneity, the principle of general covariance, and the consistency or otherwise of the special theory with quantum mechanics. Harvey Brown' s new interpretation of relativity theory will interest anyone working on these central topics in modern physics. (shrink)

One of the divine quotations narrated from the timeline of Qur’ānic revelation is seen as a word of Prophet Mohammad in the 30th verse of the surah of al-Furqān. It’s observed that the speaker of this verse is Prophet Mohammad and he complains to God about his tribe which neglects the Qur’ān. In the present study, semantic structure and the meaning area of the phrase “mahjūr”, which is the key word in this verse, the meaning of it in the timeline (...) of Qur’ānic revelation and the interpretations attributed to it in the following centuries are traced. Likewise by examining Qur’ānic exegesis chronologically and investigating the interpretations of the exegetes on the relevant verse, it’s tried to see the semantic breaking points, changes and transformations regarding this verse in the historical process. Finally, the approaches of the exegetes who interpreted this verse in terms of the method of maqāsidī tafsir or the principle of teleological interpretation are determined. The approaches detected in this respect are first explained in a descriptive style, and then they’re evaluated in an analytical point of view. The findings and conclusions we reached in this study are as follows: As stated by the majority of exegetes, especially Qatāda, al-Zamakhsharī, Ibn Atiyya, Fakhr al-Dīn al-Rāzī and al-Sa‘ālibī, the aforementioned verse belongs to the Prophet Mohammed in terms of both wording and meaning. It hasn’t been determined that there’s a conflict about the pertaining of this word to him. According to this hadith quoted in surah al-Furqān, the Qurayshi polytheists made unwarranted objections to the Prophet and the divine instructions that he brought, his heart was narrowed in the face of their attitude towards the Qur’ān, and for these reasons he complained about his tribe to God. It can be said that this meaning seen in Mecca in the tenth year of his prophethood, namely, insulting the Qur’ān, abandoning it, and denying the themes in it, also includes Muslims after the revelation period. Accordingly, it can be thought that the aspect and situation of not acting on the provisions of the Qur’ān and not thinking about its verses are also valid for the interlocutors of the next period. In this direction, when we look at the history of tafsir, it has been determined that the exegetes who interpreted this verse in terms of teleological interpretation asserted different approaches. It was seen that al-Zamakhsharī, al-Rāzī, Abū al-Barakāt al-Nasafī, al-Bikā‘ī, Kamālpasazāde, Sayhzāda and Ibn ʻĀshūr interpreted this complaint of the Prophet by associating it with the coming of punishment. Therefore, in compliance with them, this verse aimed to threaten all the interlocutors, especially the Quraysh. On the other hand, it has recognized that Ibn al-Qayyim al-Jawziyah, Ibn Kathir, Bursavī and Sayyid Qutb evaluated this verse in the context of the types and ways to abandon the Qur’ān. Thus, they interpreted the relevant verse in terms of maqāsidī tafsir in a way that would cover both the first addressees of Qur’ānic revelation and other interlocutors in the following periods. In a nutshell, it can be considered that not endeavoring to understand and interpret the Qur’ān, or keeping it away from family and social life, law, understanding of earning and spending, not referring to it in such matters, or giving up living a life pursuant to it, are some of the routes and sorts of abandonment of it for Muslims.

This paper considers the ethics of routine antenatal HIV testing and the role of informed consent within such a policy in order to decide how we should proceed in this area—a decision that ultimately rests on the relative importance we give to public health goals on the one hand and respect for individual autonomy on the other.A recent illuminating qualitative study by Zulueta and Boulton1 explores the practicalities of informed consent in routine antenatal HIV testing. Its results support what I (...) have argued1 is inevitable with routine testing policies of this kind: that routine antenatal testing regimes are incompatible with requirements for informed consent. It has become clear that intervention could reduce the risk of transmitting HIV from mother to child from 15–20%2 to around 8%,3 or possibly as low as 2%.4,5 The evidence of this possibility produced a general trend towards introducing routine antenatal HIV screening in developed countries worldwide.6,7,8,9,10 The aim was to dramatically reduce the rate of HIV transmission from mother to child by encouraging universal antenatal HIV testing. The UK has been no exception, and in 1999 the government instructed health authorities to implement a policy of offering and recommending an HIV test to all pregnant women.11This UK antenatal screening policy and others like it, although well-meaning, are problematic in their formulation. In order to reflect contemporary ethical and legal practice, such policies attempt to marry the public health aims of maximising uptake of testing with a commitment to respect the choices of patients by requiring informed consent before they participate in screening. Thus, in the case of UK policy, health professionals are instructed to recommend the HIV test to all pregnant women in order to achieve the target of a 90% …. (shrink)
