McTaggart raised a famed paradox regarding the transientist conception of time, the idea that the present moves into the future to overtake future events (or, alternatively, that future events move into the present) and past events recede further and further into the past as time goes on. Schlesinger has recently attempted an ingenious transientist solution to McTaggart's paradox. We will argue that Schlesinger's solution to McTaggart's paradox itself gives rise to a new, yet perfectly parallel, paradox which can only be (...) resolved by abandoning the transientist view of time.

Aims The purpose of this literature review was to explore the psychosocial implications of long-term survival for people affected by cancer by systematically examining published research evidence. Key findings 283 abstracts of papers were retrieved and checked and 33 studies relating to the implications of long-term survival subjected to detailed scrutiny. This review suggests that the majority of long-term cancer survivors cope well and enjoy good QoL. However, there are areas of concern which warrant attention. Whilst this review did not (...) set out to review physical problems experienced in the long-term, long-term physical consequences of cancer and its treatment were associated with poorer QoL and more psychological distress and sexual problems. Other long term concerns included anxiety regarding recurrence, financial difficulties and reduced social and emotional support. Long term survivors of lung, head and neck cancers appear particularly vulnerable to long term problems although there were few studies involving people with these cancers in this review. A number of limitations in the current evidence base were highlighted. Little research was conducted in the UK and raises questions as to the relevance of the findings for a different environment or culture where patients may have different attitudes to cancer survival and receive different treatments. Also, when looking at practical issues for long-term survivors such as ability to obtain insurance, or employment matters, then country-specific factors will be important. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:AQUINAS ON THE IMMATERIALITY OF THE INTELLECT DAVID RUEL FOSTER Seton Hall University South Orange, New Jersey I. A Controversial Question? HE QUESTION of the immateriailiity of the intelloot s,an important part of the wider question about the nau11e of the soul. The axgiumen'ts for the immaiteriality of rthe intellect a11e particularly important to Thomas's thought because they undergil1d his argument for the incorruptibility of the soul; (...) the incorruptibiility of the soul, in turn, leads towards the dootrine of the immortaility of the soruJ, a tenet of faith which Thoma.s wants to explain and deifend.1 This article will present Thomas's two most prominent arguments for the immateriality of the intieliteot and critique the first iin light of rthe seoond.2 Whether,the principle of int~Uectual ilife must, by the very 1.Arguments for the immateriality of the intellect do not necessarily appear in articles on the incorruptibility of the soul but are always presupposed by them in Thomas. For example, in Summa theologiae I, q. 75, a. 6, "Whether the human soul is incorruptible?" (" Utrum anima humana sit corruptibilis "), Thomas supports the crucial premise in his argument by referring to the,arguments for the immateriality of the intellect in articles 2 and 5 (" Utrum anima humana sit aliquid subsistens? "; "Utrum anima sit composita ex materia et forma?" Summa theologiae I, q. 75, aa. 2 and 5). 2 Five important instances of the arguments are as follows: In Sententias II, d. 19, q. 1, a. l; Summa contra gentiles II, chapters 49-50; Summa theologiae I, q. 75, aa. 2 and 5; Quaestiones Dis-putatae De anima a. 14; Oompendium theologiae, De fide, chapters 79 and 84. This chronological ordering is based on Weisheipl's catalogue in Friar Thomas D'A.quino, pp. 355-406; and Eschmann's, A Catalogue of St. Thomas's Work, in Gilson's, The Christian Philosophy of St. Thomas Aquinas, pp. 381-439. The dating of the Compendium theologiae is the most problematic. 415 416 DAVID RUEL FOSTER natUJ.1e of its.act, be immaterial is a particularly controrverted question today. Many corutempo~ary thinkers helie¥e that human understanding can be ex:pfained in strictly physical terms. ':Chis was not the case in Thomas's day, and it is important to takie notre of this. Thomas W1as noit foroed by any opponent to sharpen his arguments for the imma.teriality of the inteHect. The major Islamic philosophers, ailithough they disagreed among themselves about aspects of the inbe1iJiect's nature (e.g., the plaice and ro[e of the agent intellect)' md agree thait the intellectual soul was immaterial. Plato and Aristotle, according.to Thomas, agreed on this f.undamental point. In fact, although there were post-Socratic materialists,3 Thoma;s usuru1Jy goes ha;ek to the Pre-Socratics in order rto give an example of someone who taJUght that the inte!IJiectual :act. depends entirely on physicrul principles. Perhaps it is better to s1ay that, because the doctrine of runiversal hylomorphism was so widely accepted in his time, Thomas was not challenged regarding the incorporeality of the intellect. Many of Thoma:s's contemporaries, foililowing the tewching of Awoobroin, held that the intellectuaJ. souil was composed of spiritua.l matter.and the appropriate form,4 hut this was not in opposition to Thomas's arguments for the immateriality of the intellect. II. The Two Most Prominent Arguments A. Type I The first argument (hereaf·ter caUed Type 1) proceeds from the intellect's potential to know all corporeal things. It is justifiably described as Thomas's preferred argument,5 for s For example, the Epicureans. 4 J.

A quarter of a century ago, the first systematic behavioral experiments were performed to clarify the nature of color constancy—the effect whereby the perceived color of a surface remains constant despite changes in the spectrum of the illumination. At about the same time, new models of color constancy appeared, along with physiological data on cortical mechanisms and photographic colorimetric measurements of natural scenes. Since then, as this review shows, there have been many advances. The theoretical requirements for constancy have been (...) better delineated and the range of experimental techniques has been greatly expanded; novel invariant properties of images and a variety of neural mechanisms have been identified; and increasing recognition has been given to the relevance of natural surfaces and scenes as laboratory stimuli. Even so, there remain many theoretical and experimental challenges, not least to develop an account of color constancy that goes beyond deterministic and relatively simple laboratory stimuli and instead deals with the intrinsically variable nature of surfaces and illuminations present in the natural world.

In 1962, the philosopher Richard Taylor used six commonly accepted presuppositions to imply that human beings have no control over the future. David Foster Wallace not only took issue with Taylor's method, which, according to him, scrambled the relations of logic, language, and the physical world, but also noted a semantic trick at the heart of Taylor's argument. _Fate, Time, and Language_ presents Wallace's brilliant critique of Taylor's work. Written long before the publication of his fiction and essays, (...) Wallace's thesis reveals his great skepticism of abstract thinking made to function as a negation of something more genuine and real. He was especially suspicious of certain paradigms of thought-the cerebral aestheticism of modernism, the clever gimmickry of postmodernism-that abandoned "the very old traditional human verities that have to do with spirituality and emotion and community." As Wallace rises to meet the challenge to free will presented by Taylor, we witness the developing perspective of this major novelist, along with his struggle to establish solid logical ground for his convictions. This volume, edited by Steven M. Cahn and Maureen Eckert, reproduces Taylor's original article and other works on fatalism cited by Wallace. James Ryerson's introduction connects Wallace's early philosophical work to the themes and explorations of his later fiction, and Jay Garfield supplies a critical biographical epilogue. (shrink)

Galgan wants to write a biography of being, and the character witnesses are Aristotle, Anselm, Descartes, and Feuerbach. The main points are that Anselm is a pivot between a classical and modern view of God in first philosophy, and that modern philosophers gave up the search for God by claiming to have found God to be man. Thus God was replaced by subjectivity--our subjectivity. The book is not a textual study, but does give a fairly close commentary on texts of (...) Anselm, Descartes, and Feuerbach. (shrink)

Richard Connell’s book brings together Aristotle’s great metaphysical insight, that everything has four causes, with the discoveries of modern natural science. Whereas many contemporary philosophers and natural scientists think the question of the nature and number of causes is irrelevant or resolved, Connell thinks that they are indispensable distinctions that have been mauled beyond recognition.

For a stable visual world, the colours of objects should appear the same under different lights. This property of colour constancy has been assumed to be fundamental to vision, and many experimental attempts have been made to quantify it. I contend here, however, that the usual methods of measurement are either too coarse or concentrate not on colour constancy itself, but on other, complementary aspects of scene perception. Whether colour constancy exists other than in nominal terms remains unclear.

R. J. Henle, one of the few philosophers to have a village named after him, has published the fruit of his twenty-plus years of teaching epistemology. The book is intended to be both a textbook and a contribution to philosophical literature.

The most striking feature of Leo Elders’s book is the broad context with which he surrounds Thomas’s doctrine of nature. For example, his discussion of the soul provides a good review of the doctrine before and after Thomas, his discussion of “time” takes us from Parmenides to Einstein. Because Elders wants to refute those who think the doctrine of Thomas is simply of historical interest, he consistently relates Thomas’s teaching to the contemporary state of the question. He does a credible (...) job of discussing everything from general field theory, to quarks, to cell biology. (shrink)

On its twenty-fifth anniversary, Fides et ratio remains relevant for its bold defense of reason and the complementarity of faith and reason. It describes a philosophy that is not the preserve of academics but the duty of every person. It asserts that philosophy is never contained in one system but is always open to new questions and further insights. St. John Paul defends a philosophy that welcomes pluralism based on the richness of being but rejects a pluralism based on the (...) impossibility of knowing the truth. Reflecting on Fides et ratio, this article describes six ways that theology uses philosophy and offers five lessons for philosophers, i.e., the universal character of philosophy, the complementarity of faith and reason, the necessity and limits of pluralism, the requirements for a philosophy to be consonant with theology, and the current reinvigoration of philosophy in seminaries.

Shepard's analysis of how shape, motion, and color are perceptually represented can be generalized. Apparent motion and shape may be associated with a group of spatial transformations, accounting for rigid and plastic motion, and perceived object color may be associated with a group of illuminant transformations, accounting for the discriminability of surface-reflectance changes and illuminant changes beyond daylight. The phenomenological and mathematical parallels between these perceptual domains may indicate common organizational rules, rather than specific ecological adaptations. [Barlow; Hecht; Kubovy & (...) Epstein; Schwartz; Shepard; Todorovic]. (shrink)

As psychology ethics begins to become more standardized and formalized globally (e.g., Gauthier, 2007) there are still educational, political, and psychological areas that require significant discussion. For example, test security has become a global issue, as psychological tests and even college entrance and graduate school admission tests have found their way online.

Small changes in daylight in the environment can produce large changes in reflected light, even over short intervals of time. Do these changes limit the visual recognition of surfaces by their colour? To address this question, information-theoretic methods were used to estimate computationally the maximum number of surfaces in a sample that can be identified as the same after an interval. Scene data were taken from successive hyperspectral radiance images. With no illumination change, the average number of surfaces distinguishable by (...) colour was of the order of 10,000. But with an illumination change, the average number still identifiable declined rapidly with change duration. In one condition, the number after two minutes was around 600, after 10 min around 200, and after an hour around 70. These limits on identification are much lower than with spectral changes in daylight. No recoding of the colour signal is likely to recover surface identity lost in this uncertain environment.

The aims of this dissertation are to categorize, clarify, and assess Thomas' arguments for the immateriality of the intellect. ;The five principal texts are: Scriptum super Libros Sententiarum II, d.19, q.1, a.1; Summa Contra Gentiles II, Chapters 49 and 50; Summa Theologiae I, q.75, aa.2, 5; Quaestiones Disputatae De anima, a.14; and Compendium Theologiae, Chapters 79 and 84. ;Of the thirty-six arguments for the immateriality of the intellect surveyed, thirty of them can be collected under five basic types. Type 1 (...) argues that since the intellect is in potency to know all sensible things it must not be composed of any sensible thing. Type 2--the intellect's grasp of the universal transcends the limits of matter and therefore it could not be composed of matter. Type 3--since knowing involves the unity of knower and known, impossible consequence follow if the intellect were material. Type 4--if the intellect were a material organ then it could not know itself as it does. Type 5--while contraries cannot exist together in a body, they do exist together in the intellect. ;Although some new arguments are introduced and others are dropped, types 1 and 2 remain the primary arguments throughout Thomas' career. Type 1 is preferred by Thomas, but it is actually type 2 that is most pervasive. The expression of type 2 varies more than that of type 1; type 2 is often combined with elements of other arguments, an indication of its fundamental character among these arguments. I argue that type 2 is the most fundamental argument for the immateriality of the intellect, and is most promising for use in the present day. ;Type 1 is an incomplete rendering of Aristotle and is inconsistent with Thomas' own description of the internal sense powers. Insofar as one fortifies type 1 by pointing to the different way the intellect has its object , one is actually using type 2 to maintain type 1. Furthermore, type 1 does not allow a proper assimilation of modern findings about brain function, and finally, it does a disservice to the unity of the person. (shrink)

We examine the impact of a unilateral carbon tax in developed countries, focusing on the expected size of carbon leakage and the effects on leakage of border tax adjustments. We start by analyzing the problem using a simple two-country, three-good general equilibrium model to develop intuitions. We then simulate the expected size of the effects using a new, open-source, computable general equilibrium model. We analyze the extent of emissions reductions from a carbon tax in countries that made commitments under the (...) Kyoto Protocol, the expected carbon leakage, and the effects of border tax adjustments on carbon leakage, all relative to our baseline projections for emissions. We also perform extensive sensitivity tests on the parameters of the CGE model. Finally, we consider the effects of imperfect border tax adjustments on leakage, such as global or regional schedules of border taxes. (shrink)

An important factor in judging whether two retinal images arise from the same object viewed from different positions may be the presence of certain properties or cues that are 'qualitative invariants' with respect to the natural transformations, particularly affine transformations, associated with changes in viewpoint. To test whether observers use certain affine qualitative cues such as concavity, convexity, collinearity, and parallelism of the image elements, a 'same-different' discrimination experiment was carried out with planar patterns that were defined by four points (...) either connected by straight line segments (line patterns) or marked by dots (dot patterns). The first three points of each pattern were generated randomly; the fourth point fell on their diagonal bisector. According to the position of that point, the patterns were concave, triangular (three points being collinear), convex, or parallel sided. In a 'same' trial, an affine transformation was applied to one of two identical patterns; in a 'different' trial, the affine transformation was applied after the point lying on the diagonal bisector was perturbed a short, fixed distance along the bisector, inwards for one pattern and outwards for the other. Observers' ability to discriminate 'same' from 'different' pairs of patterns depended strongly on the position of the fourth, displaced, point: performance varied rapidly when the position of the displaced point was such that the patterns were nearly triangular or nearly parallel sided, consistent with observers using the hypothesised qualitative cues. The experimental data were fitted with a simple probabilistic model of discrimination performance that used a combination of these qualitative cues and a single quantitative cue. (shrink)

This paper consists of commentaries about and the reprint of an autobiographical essay authored by Italian medium Eusapia Palladino and published in 1910. The details of the essay are discussed in terms of the writings of other individuals about the life and performances of the medium. The essay conveys a view of Palladino as a person who has suffered much in life and has a mission to help scientific research into mediumship. Typical of the positive emphasis in autobiographies in general, (...) the medium did not discuss negative aspects of her performances. Due to the fact that the essay appeared during Palladino's visit to New York City in which many authors branded her as a fraud, it may be speculated that the purpose of this autobiography was to elicit sympathy from the American public. While some of the statements that Palladino made about phenomena are consistent with the statements of other authors who have written about her, there are several statements that show alternate or incomplete versions of particular events in her life. The differences suggests that Palladino's essay and other discussions about the medium's life are not reliable when it comes to specific details and to biographical accuracy. (shrink)

Naive observers viewed a sequence of colored Mondrian patterns, simulated on a color monitor. Each pattern was presented twice in succession, first under one daylight illuminant with a correlated color temperature of either 16,000 or 4,000 K and then under the other, to test for color constancy. The observers compared the central square of the pattern across illuminants, either rating it for sameness of material appearance or sameness of hue and saturation or judging an objective property—that is, whether its change (...) of color originated from a change in material or only from a change in illumination. Average color constancy indices were high for material appearance ratings and binary judgments of origin and low for hue–saturation ratings. Individuals’ performance varied, but judgments of material and of hue and saturation remained demarcated. Observers seem able to separate phenomenal percepts from their ontological projections of mental appearance onto physical phenomena; thus, even when a chromatic change alters perceived hue and saturation, observers can reliably infer the cause, the constancy of the underlying surface spectral reflectance.

Each essay is a comprehensive introduction to the thought of a noted American on the fundamental meaning of the American regime.

David Hume's claim that necessary connection is essential to causality was at the expense of a useful causal distinction we sometimes note with the words ‘necessity’ and ‘contingency’. And since, as J. L. Mackie has stated, Hume made ‘the most significant and influential single contribution to the theory of causation’, subsequent writers on causality, regardless of their support for, or opposition to, Hume, have joined him in trampling this distinction. The object of this paper is not so much to (...) undermine one of Hume's conclusions as it is to describe a use of ‘necessary’ that, while surviving in popular usage, is ignored or obfuscated in the literature on causality.

Many prescriptions offered in the literature for enhancing creativity and innovation in organizations raise ethical concerns, yet creativity researchers rarely discuss ethics. We identify four categories of behavior proffered as a means for fostering creativity that raise serious ethical issues: breaking rules and standard operating procedures; challenging authority and avoiding tradition; creating conflict, competition and stress; and taking risks. We discuss each category, briefly identifying research supporting these prescriptions for fostering creativity and then we delve into ethical issues associated with (...) engaging in the prescribed behavior. These four rubrics illustrate ethical issues that need to be incorporated into the creativity and innovation literature. Recommendations for how organizations can respond to the ethical issues are offered based on practices of exemplary organizations and theories of organizational ethics. A research agenda for empirically investigating the ethical impact these four categories of behavior have on organizations concludes the article. (shrink)

The American Philosophical Association suggests that studying philosophy can have an important impact on one's creative thinking ability. This paper abstracts from the empirical research on creativity a reasonable model of creative thinking, and discusses what the account implies about fostering creative thinking in philosophy courses. Given the empirical research on creativity and the nature of philosophy, studying philosophy can have an important impact on one's creative thinking ability, but faculty need to focus on it in their courses.

Liberal education has been under siege in recent years. Far-right ideologues in journalism and government have pressed for a uniform curriculum that focuses on the achievements of Western culture. Partisans of the academic left, who hold our culture responsible for the evils of society, have attempted to redress imbalances by fostering multiculturalism in education. In this eloquent and passionate book a distinguished scholar criticizes these positions and calls for a return to the tradition of independent thinking that he contends has (...) been betrayed by both right and left. Under the guise of educational reform, says David Bromwich, these groups are in fact engaging in politics by other means. Bromwich argues that rivals in the debate over education have one thing in common: they believe in the all-importance of culture. Each assumes that culture confers identity, decides the terms of every moral choice, and gives a meaning to life. Both sides therefore see education as a means to indoctrinate students in specific cultural and political dogmas. By contrast, Bromwich contends that genuine education is concerned less with culture than with critical thinking and independence of mind. This view of education is not a middle way among the political demands of the moment, says Bromwich. Its earlier advocates include Mill and Wollstonecraft, and its roots can be traced to such secular moralists as Burke and Hume. Bromwich attacks the anti-democratic and intolerant premises of both right and left - premises that often appear in the conservative guise of "preserving the tradition" on the one hand, or the radical guise of "opening up the tradition" on the other. He discusses the new academic"fundamentalists" and the politically correct speech codes they have devised to enforce a doctrine of intellectual conformity; educational policy as articulated by conservative apologists George Will and William Bennett; the narrow logic of institutional radicalism; the association between personal reflection and social morality; and the discipline of literary study, where the symptoms of cultural conflict have appeared most visibly. Written with the wisdom and conviction of a dedicated teacher, this book is a persuasive plea to recover a true liberal addition in academia and government - through independent thinking, self-knowledge, and tolerance of other points of view.
