When looking at a scene, observers feel that they see its entire structure in great detail and can immediately notice any changes in it. However, when brief blank fields are placed between alternating displays of an original and a modified scene, a striking failure of perception is induced: identification of changes becomes extremely difficult, even when changes are large and made repeatedly. Identification is much faster when a verbal cue is provided, showing that poor visibility is not the cause of (...) this difficulty. Identification is also faster for objects mentioned in brief verbal descriptions of the scene. These results support the idea that observers never form a complete, detailed representation of their surroundings. In addition, results also indicate that attention is required to perceive change, and that in the absence of localized motion signals it is guided on the basis of high-level interest. (shrink)

This study seeks to present the theory of freedom as found in one line of the Marxist tradition, that which begins with Marx and Engels and continues through Lenin to contemporary Soviet philosophy. Although the primary goal is simply to describe how freedom is con ceived by the thinkers of this tradition, an attempt is also made to ascertain whether or not their views are strongly deterministic, as has often been presumed by Western commentators. is in order regarding the scope (...) of the term 'contemporary A remark Soviet philosophy'. The Soviet stage in Marxist philosophy stretche. s back to the 1917 revolution. However, for the purposes of this study only works published after 1947 were examined, and the vast majority of them date from the 1960's. Apart from the fact that most works of previous periods were not available, bibliographical indications, such as the titles of the articles in Pod znamenem marksizma, did not suggest that the theory of freedom was then a major concern. In fact, even 1947 there was little development of this theme until the upsurge after of works in philosophical anthropology during the last decade. On the other hand, it is not being suggested that the conception of freedom found in recent writings is representative of earlier Soviet philosophy, during the Stalinist 'dead' period or earlier. Only further research could establish that. This work was presented as a doctoral dissertation at the University of Fribourg, Switzerland, under the direction of Professor J. M. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Commentary on Augustine City of God, Books 1–5 by Gillian ClarkJames J. O'DonnellCommentary on Augustine City of God, Books 1–5. By Gillian Clark. Oxford: Oxford University Press, 2021. Pp. xii + 281. ISBN: 978-0-19-887007-4.Pierre Bayard's masterful How to Talk about Books You Haven't Read offers soothing balm for readers in the daunting presence of Augustine's City of God. Weighing in at a third of a million words, Augustine's (...) magnum opus et arduum,1 offers a Moby-Dick and a half of verbiage spread out over twenty-two books. I make the claim, nervously and looking about for intelligent contradiction, that it is the longest work of sustained and coherent argument to survive from Greco-Roman antiquity. Other behemoths are compilations in the main of one kind or another, but this one has a structure and a linear direction and was tightly enough written that a theme opened in the second book with a promise of returning with later treatment is in fact picked up in the nineteenth book written perhaps a dozen years later.Those who really will read, or at least read in, Civ. benefit from all the help they can get. There are good translations (English alone in my lifetime by McCracken et al. in Loeb, Bettenson, Dyson, and Babcock) but none provides more than a minimalist annotation. Francophone readers have been better served since 1960 by the five volume edition with more ample annotation in the Bibliothèque Augustinienne of G. Bardy et al., and it is the standard point of entrance to serious study for scholars. That work has many strengths but the limitations of arising from a devout tradition of scholarship and of coming before the efflorescence in late antique and Augustinian studies through which we have lived.More help is now at hand in the form of the volume under review and its promise of more to come. Gillian Clark is known and admired among Augustinian scholars for many works, not least the earlier exercise in commentary of her Cambridge "green and yellow"2 edition of Confessions 1–4 (1995). The present work began as an ambitious multi-author collaborative project that proved unwieldy (see the present volume, pp. 31–32) and results in this first installment of [End Page 179] a series now in Clark's hands exclusively, drawing on her strengths as a classical historian specializing in late antiquity and patristics. Four additional volumes are anticipated, ideally on two-year intervals. The task requires multiple competences: at least, the history of the fourth and fifth centuries, the history and presence of ancient philosophy, the history of Christian reception and interpretation of scripture, and the reception of classical literature in late antiquity. It is a work that soars with no middle flight.As commentary on a behemoth, the commentary begins with the virtue of concision. At a rough calculation, commentary here runs at about half again the length of the text under review, producing volumes that can be usefully read alongside Augustine without swamping either Augustine or the reader in an ocean of erudition and detail. After an introduction that is as much to the whole work as to books 1–5, the book is organized strictly by lemmata to passages commented. The lemmata are all in Latin to facilitate use by readers of various editions and translations, with references given by book/chapter and page/line to the standard CCSL 1955 reprinting of the edition of Dombart-Kalb (itself originally a Teubner of 1928).3The focus of the annotation is on the work as historical artifact, well situated in both the moment and controversies of writing and in the apparatus of learning that Augustine brought to his work. Inevitably this includes welcome discussion of argument, rhetoric, and strategy (the very short discussion of how Augustine wrote on pp. 9–12 is remarkably insightful), but readers will welcome the lucid guidance offered to how the text made sense in Aug.'s own time, to what he was evidently reading as he wrote, and to the range of historical realia that make up his argument.

There is an anomaly about the origins of Augustine’s great work of anti-pagan polemic and Christian apologetic that has not been accorded due weight in discussion of the development of the work’s idea in Augustine’s mind. The purpose of this brief note is to point out a hitherto unrecognized explanation for this anomaly, while leaving aside a full-scale development of the implications of this discovery.

In CQ n.s 32 , 237, Howard Jacobson comments on Lucretius' expression fingere somnia, for which he can find only two parallels, both later than Lucretius. He suggests that the phrase can best be understood as a reference to the actual practice of dream control, or oneiropompeia, for which he provides several useful references. A fragment of Luciiius, however, provides not only a parallel, but perhaps even a model, for Lucretius' phrase, and for his criticism in 1.102–35 of the lies (...) or fictions of both religious figures and poets.

In CQ 34 , 167–74, Janet Fairweather makes the interesting suggestion that the elegiacs by Gallus on the Qasr Ibrim papyrus should be understood as ‘a fragment of an amoebaean song-contest’. This hypothesis, as she notes, might explain why the papyrus' quatrains are set apart by spaces and by an odd type of symbol, and treat ‘separate, indeed discrepant, topics’, yet show ‘unmistakable verbal and thematic connections’. Fairweather's discussion is thorough, but overlooks one small piece of evidence for Gallan amoebaean (...) verse. (shrink)

Observers inspected normal, high quality color displays of everyday visual scenes while their eye movements were recorded. A large display change occurred each time an eye blink occurred. Display changes could either involve "Central Interest" or "Marginal Interest" locations, as determined from descriptions obtained from independent judges in a prior pilot experiment. Visual salience, as determined by luminance, color, and position of the Central and Marginal interest changes were equalized. -/- The results obtained were very similar to those obtained in (...) prior experiments showing failure to detect changes occurring simultaneously with saccades, flicker, or “mudsplashes” in the visual scene: Many changes were very hard to detect, and Marginal Interest changes were harder to detect than Central Interest changes. -/- Analysis of eye movements showed, as expected, that the probability of detecting a change depended on the eye’s distance from the change location. However a surprising finding was that both for Central and Marginal Interest changes, evenwhen observers were directly fixating the change locations (within 1 degree),more than 40% of the time they still failed to see the changes. It seems that looking at something does not guarantee you “ see” it. (shrink)

When brief blank fields are placed between alternating displays of an original and a modified scene, a striking failure of perception is induced: the changes become extremely difficult to notice, even when they are large, presented repeatedly, and the observer expects them to occur (Rensink, O'Regan, & Clark, 1997). To determine the mechanisms behind this induced "change blindness", four experiments examine its dependence on initial preview and on the nature of the interruptions used. Results support the proposal that representations at (...) the early stages of visual processing are highly volatile, and that focused attention is needed to stabilize them sufficiently to support the perception of change.

Change-blindness occurs when large changes are missed under natural viewing conditions because they occur simultaneously with a brief visual disruption, perhaps caused by an eye movement, a flicker, a blink, or a camera cut in a film sequence. We have found that this can occur even when the disruption does not cover or obscure the changes. When a few small, high-contrast shapes are briefly spattered over a picture, like mudsplashes on a car windscreen, large changes can be made simultaneously in (...) the scene without being noticed.

Public health ethics, like the field of public health it addresses, traditionally has focused more on practice and particular cases than on theory, with the result that some concepts, methods, and boundaries remain largely undefined. This paper attempts to provide a rough conceptual map of the terrain of public health ethics. We begin by briefly defining public health and identifying general features of the field that are particularly relevant for a discussion of public health ethics.Public health is primarily concerned with (...) the health of the entire population, rather than the health of individuals. Its features include an emphasis on the promotion of health and the prevention of disease and disability; the collection and use of epidemiological data, population surveillance, and other forms of empirical quantitative assessment; a recognition of the multidimensional nature of the determinants of health; and a focus on the complex interactions of many factors—biological, behavioral, social, and environmental—in developing effective interventions.
