Attention Restoration Theory proposes that exposure to natural environments helps to restore attention. For sustained attention—the ongoing application of focus to a task, the effect appears to be modest, and the underlying mechanisms of attention restoration remain unclear. Exposure to nature may improve attention performance through many means: modulation of alertness and one’s connection to nature were investigated here, in two separate studies. In both studies, participants performed the Sustained Attention to Response Task before and immediately after viewing a meadow, (...) ocean, or urban image for 40 s, and then completed the Perceived Restorativeness Scale. In Study 1, an eye-tracker recorded the participants’ tonic pupil diameter during the SARTs, providing a measure of alertness. In Study 2, the effects of connectedness to nature on SART performance and perceived restoration were studied. In both studies, the image viewed was not associated with participants’ sustained attention performance; both nature images were perceived as equally restorative, and more restorative than the urban image. The image viewed was not associated with changes in alertness. Connectedness to nature was not associated with sustained attention performance, but it did moderate the relation between viewing the natural images and perceived restorativeness; participants reporting a higher connection to nature also reported feeling more restored after viewing the nature, but not the urban, images. Dissociation was found between the physiological and behavioral measures and the perceived restorativeness of the images. The results suggest that restoration associated with nature exposure is not associated with modulation of alertness but is associated with connectedness with nature. (shrink)

This paper is concerned with the notion of ambiguity—or what I shall refer to more generally as homonymy—and its bearing upon various familiar puzzles about intensional contexts. It would hardly of course be a novel claim that the unravelling of such puzzles may well involve recourse to something like ambiguity. After all, Frege, who bequeathed to us one of the most enduring of the puzzles, proposed as part of his solution an analysis of intensional contexts according to which all expressions (...) change their sense when embedded in such contexts. And many contemporary philosophers who have discussed the puzzles, while not perhaps endorsing Frege's own somewhat extreme view, nevertheless take ambiguities in the contained sentences to be the key to the puzzles. In this paper, however, I wish to follow those who take the crucial source of homonymy, at least in the most difficult of the puzzles, to lie primarily not in the embedded sentences, but rather in the intensional verbs that embed them. I begin with a brief examination of certain aspects of ambiguity and homonymy. (shrink)

This paper shows how the dream archive and search engine on DreamBank.net, a Web site containing over 22,000 dream reports, can be used to generate new findings on dream content, some of which raise interesting questions about the relationship between dreaming and various forms of waking thought. It begins with studies that draw dream reports from DreamBank.net for studies of social networks in dreams, and then demonstrates the usefulness of the search engine by employing word strings relating to religious and (...) sexual elements. Examples from two lengthy individual dream series are used to show how the dreams of one person can be studied for characters, activities, and emotions. A final example shows that accurate inferences about a person’s religious beliefs can be made on the basis of reading through dreams retrieved with a few keywords. The overall findings are similar to those in studies using traditional forms of content analysis. (shrink)

Henri Bergson created a rich and detailed theory of consciousness beginning with the publication of Time and Free Will in 1889 and continuing through the publication of The Two Sources of Morality and Religion in 1932. His theory had much in common with William James’s views in that both emphasized consciousness as a continuous process. James's famous ‘stream of consciousness’ is strikingly similar to Bergson's early notion of duration (duree), even if Bergson more strongly emphasized the temporal qualities of consciousness. (...) Bergson later modified his understanding of consciousness, creating a metaphysical vision that he hoped might not only overcome determinism and materialism, but also offer a sophisticated way to understand parapsychological phenomena such as telepathy and clairvoyance (topics of concern to many major theorists of the time). During his life, Bergson’s ideas were widely celebrated in the United States and in Europe. (shrink)

T. H. Huxley (1825-1895) was not only an active protagonist in the religious and scientific upheaval that followed the publication of Darwin's theory of evolution but also a harbinger of the sociobiological debates about the implications of evolution that are now going on. His seminal lecture Evolution and Ethics, reprinted here with its introductory Prolegomena, argues that the human psyche is at war with itself, that humans are alienated in a cosmos that has no special reference to their needs, and (...) that moral societies are of necessity in conflict with the natural conditions of their existence. Seen in the light of current understanding of the mechanisms of evolution, these claims remain as controversial today as they were when Huxley proposed them. In this volume George Williams, one of the best-known evolutionary biologists of our time, asserts that recent biological ideas and data justify a more extreme condemnation of the "cosmic process" than Huxley advocated and more extreme denial that the forces that got us here are capable of maintaining a viable world. James Paradis, an expert in Victorian studies, has written an introduction that sets the celebrated lecture in the context of cultural history, revealing it to be an impressive synthesis of Victorian thinking, as well as a challenge to eighteenth-century assumptions about the harmony of of nature. With Huxley's lecture as a focal point, the three parts of this book unite philosophy and science in a shared quest that recalls their common origins as systems of knowledge.

Neurological syndromes in which consciousness seems to malfunction, such as temporal lobe epilepsy, visual scotomas, Charles Bonnet syndrome, and synesthesia offer valuable clues about the normal functions of consciousness and ‘qualia’. An investigation into these syndromes reveals, we argue, that qualia are different from other brain states in that they possess three functional characteristics, which we state in the form of ‘three laws of qualia ’ based on a loose analogy with Newton’s three laws of classical mechanics. First, they are (...) irrevocable: I cannot simply decide to start seeing the sunset as green, or feel pain as if it were an itch; second, qualia do not always produce the same behaviour: given a set of qualia, we can choose from a potentially infinite set of possible behaviours to execute; and third, qualia endure in short-term memory, as opposed to non-conscious brain states involved in the on-line guidance of behaviour in real time. We suggest that qualia have evolved these and other attributes (e.g. they are ‘filled in’) because of their role in facilitating non-automatic, decision-based action. We also suggest that the apparent epistemic barrier to knowing what qualia another person is experiencing can be overcome simply by using a ‘bridge ’ of neurons; and we offer a hypothesis about the relation between qualia and one’s sense of self.

Lycan (1985, 1988) defended a “Principle of Credulity”: “Accept at the outset each of those things that seem to be true” (1988, p. 165). Though that takes the form of a rule rather than a thesis, it does not seem very different from Huemer’s (2001, 2006, 2007) doctrine of phenomenal conservatism (PC): “If it seems to S that p , then, in the absence of defeaters, S thereby has at least some degree of justification for believing that p ” (2007, (...) p. 30). My Principle was differently motivated and put to uses different from Huemer’s. In this paper I shall explore some of the differences. (shrink)

Supervaluationism is often described as the most popular semantic treatment of indeterminacy. There’s little consensus, however, about how to fill out the bare-bones idea to include a characterization of logical consequence. The paper explores one methodology for choosing between the logics: pick a logic thatnorms beliefas classical consequence is standardly thought to do. The main focus of the paper considers a variant of standard supervaluational, on which we can characterizedegrees of determinacy. It applies the methodology above to focus ondegree logic. (...) This is developed first in a basic, single-premise case; and then extended to the multipremise case, and to allowdegreesof consequence. The metatheoretic properties of degree logic are set out. On the positive side, the logic is supraclassical—all classical valid sequents are degree logic valid. Strikingly, metarules such as cut and conjunction introduction fail. (shrink)

Now in its Third Edition, Philosophy of Language: A Contemporary Introduction introduces students to the main issues and theories in twentieth-century philosophy of language, focusing specifically on linguistic phenomena. Author William G. Lycan structures the book into four general parts. Part I, Reference and Referring, includes topics such as Russell's theory of descriptions (and its objections), Donnellan's distinction, problems of anaphora, the description theory of proper names, Searle's cluster theory, and the causal-historical theory. Part II, Theories of Meaning, surveys the (...) competing theories of linguistic meaning and compares their various advantages and liabilities. Part III, Pragmatics and Speech Acts, introduces the basic concepts of linguistic pragmatics and includes a detailed discussion of the problem of indirect force. Part IV, The Expressive and the Figurative, examines various forms of expressive language and what "metaphorical meaning" is and how most listeners readily grasp it. (shrink)

Using a combination of network analysis and descriptive statistics, this study examines the extent to which six important and longstanding policy-oriented nonprofit organizations — foundations, think tanks, and policy-discussion groups — were connected via their directors with the 250 largest corporations in the United States in 1935–1936 and 2010–2011. The results demonstrate that the six nonprofit organizations included in the study were well integrated into corporate networks in both periods, and had an even greater integrative role in 2010–2011 than they (...) did in 1935–1936. This finding supports the hypothesis that policy-oriented nonprofit organizations allow the corporate community to develop proposals, and to reach consensus, on major policy issues. This hypothesis is further supported by an overview of existing studies that illustrate the success of these organizations in shaping policy outcomes on a range of issues. Based on the overall results, the longstanding claim that corporations influence government primarily or solely at the “interest-group” level can be supplemented by the conclusion that policy-oriented nonprofits support a policy-planning process that links the corporate community to government on general issues. In addition, the findings cast doubt on the claim that the corporate community has lost its capacity for policy cohesion in recent decades, due primarily to a “fracturing” caused by a decline in bank centrality. Since general policies have been created within the policy-planning process since at least the mid-1930s, the decline in bank centrality is irrelevant to the corporate community’s ability to formulate general policy proposals.

The United States has long been a model for accessible, affordable education, as exemplified by the country's public universities. And yet less than 60 percent of the students entering American universities today are graduating. Why is this happening, and what can be done? Crossing the Finish Line provides the most detailed exploration ever of college completion at America's public universities. This groundbreaking book sheds light on such serious issues as dropout rates linked to race, gender, and socioeconomic status. Probing graduation (...) rates at twenty-one flagship public universities and four statewide systems of public higher education, the authors focus on the progress of students in the entering class of 1999--from entry to graduation, transfer, or withdrawal. They examine the effects of parental education, family income, race and gender, high school grades, test scores, financial aid, and characteristics of universities attended. The conclusions are compelling: minority students and students from poor families have markedly lower graduation rates--and take longer to earn degrees--even when other variables are taken into account. Noting the strong performance of transfer students and the effects of financial constraints on student retention, the authors call for improved transfer and financial aid policies, and suggest ways of improving the sorting processes that match students to institutions. An outstanding combination of evidence and analysis, Crossing the Finish Line should be read by everyone who cares about the nation's higher education system. (shrink)

Davidson made a strikingly distinctive and valuable contribution to the practice of ontology. It was a species of argument for the existence of things of one kind or another. It combined Quine's doctrine that “To be is to be the value of a bound variable” with Davidson's own apparently anti‐Quinean views on semantics and logical form in natural language. Roughly: Suppose truth‐conditional analysis of certain English sentences assigns them logical forms containing characteristic quantifiers, and the quantifiers' domains include entities of (...) a certain sort. Then, assuming that some of the relevant sentences are true, it follows that there exist entities of that sort. This chapter expounds Davidson's extended defense of that method, and then considers and tries to rebut five potential objections to it. (shrink)

The eight books of The Letters of George Santayana bring together over 3,000 letters, many of which have been discovered in the fifty years since Santayana's death. This sixth book covers four years of Santayana's life in Rome, his permanent residence since the late 1920s. During these years, Santayana, in his seventies, saw the publication of the remaining nine volumes of the Triton Edition of his work as well as the last two books of his Realms of Being: The Realm (...) of Truth and The Realm of Spirit. In 1938 the first book-length biography of Santayana was published, and in 1940 The Philosophy of George Santayana--a collection of critical essays that included Santayana's rejoinder, "Apologia pro Mente Sua"--was published as volume two of Northwestern University Press?s Library of Living Philosophers. In 1939, when war broke out in Europe and Swiss authorities denied him a long-term visa, Santayana decided to stay in Italy, where he was to remain for the rest of his life.The letters in this book are written to such correspondents as Van Meter Ames, Curt John Ducasse, Max Forrester Eastman, Max Fisch, Sidney Hook, Horace Meyer Kallen, Christopher Janus, Milton Munitz, William Lyon Phelps, and Ezra Pound, and include discussions of the work of Henri Bergson, T. S. Eliot, William Faulkner, and Ezra Pound, among others. (shrink)

This final volume of Santayana's letters spans the last five years of the philosopher's life. Despite the increasing infirmities of age and illness, Santayana continued to be remarkably productive during these years, working steadily until September 1952, when he died of stomach cancer, just three months short of his eighty-ninth birthday. Still living in the nursing home run by the "Blue Sisters" of the Little Company of Mary in Rome, Santayana completed his book Dominations and Powers, which had been more (...) than fifty years in the making, the final part of his autobiography Persons and Places, published posthumously in 1953 as My Host the World, and the abridgement of his early five-part masterwork, The Life of Reason, into a single volume--all while continuing to maintain a voluminous correspondence with friends and admirers. The eight books of The Letters of George Santayana bring together over 3,000 letters, many of which have been discovered in the fifty years since Santayana's death. Letters in Book Eight are written to such correspondents as the young American poet Robert Lowell ; Ira D. Cardiff, the editor of Atoms of Thought, a collection of excerpts from Santayana's writings ; Richard Colton Lyon, a young Texan who would later collect Santayana's writings about America in Santayana on America: Essays, Notes, and Letters on American Life, Literature, and Philosophy ; and the humanist philosopher Corliss Lamont.William G. Holzberger is Professor of English Emeritus at Bucknell University. (shrink)

This penultimate volume of Santayana's letters chronicles Santayana's life during a difficult time--the war years and the immediate postwar period. The advent of World War II left Santayana isolated in Rome, and the difficulties of wartime travel across borders forced him to abandon plans to move to more agreeable locations in Switzerland or Spain. During these years, Santayana lived in a single room in a nursing home run by the "Blue Sisters" of the Little Company of Mary in Rome, where, (...) during the winter months, he did much of his writing in bed in order to stay warm. And yet, despite wartime deprivations, illness, and old age, Santayana was remarkably productive, completing both his autobiography Persons and Places and The Idea of Christ in the Gospels: or God in Man, and all but completing Dominations and Powers. He confided to one correspondent that he had "never been more at peace or more happy."The eight books of The Letters of George Santayana bring together over 3,000 letters, many of which have been discovered in the fifty years since Santayana's death. Letters in Book Seven are written to such correspondents as his friend and protégée Daniel Cory, his financial manager and heir George Sturgis, and the American poet Robert Lowell. The correspondence with Lowell--which began when the younger writer sent Santayana a copy of his Pulitzer Prize-winning Lord Weary's Castle--signals an important new friendship, which became a source of affection and intellectual engagement in Santayana's final years.

In two recent publications I argued against Nemirow and Lewis that there is distinctive, irreducibly phenomenal and perspectival information of the sort alleged by Jackson; but I gave an account of such information that is entirely compatible with a materialist view of human subjects. Hershfield argues that the latter account is inadequate, in that it fails to support the claim that the information it characterizes is irreducibly phenomenal or perspectival. I reply that Hershfield's conclusion does not follow from his argument's (...) premises. (shrink)

We review the role of reference within Davidson's T‐theoretic account of language and examine his contention that reference is inscrutable. More generally, we look at the explanatory role of reference in the context of Davidson's philosophy: whether there are explanations that directly appeal to reference, and whether there are explanations that appeal to beliefs about reference.

The study examined the influence of the Pond Report on the teaching of medical ethics in the London medical schools. A questionnaire was given to both medical students and college officers. All medical colleges reported that ethics was included in the curriculum. However, from students' replies, it seems that attendance of optional courses is low and that not all current final year medical students have had any formal teaching in medical ethics. Stronger guidelines are necessary to ensure appropriate ethical training (...) in London medical schools. (shrink)

Objective: To determine the usefulness of Q methodology to locate and describe shared subjective influences on clinical decision making among participant physicians using hypothetical cases containing common ethical issues. Design: Qualitative study using by-person factor analysis of subjective Q sort data matrix. Setting: University medical center. Participants: Convenience sample of internal medicine attending physicians and house staff (n = 35) at one midwestern academic health sciences center. Interventions: Presented with four hypothetical cases involving urgent decision making near the end of (...) life, participants selected one of three specific clinical actions offered for each case. Immediately afterward and while considering their decision, each respondent sorted twenty-five subjective self-referent items in terms of the influence of each statement on their decision-making process. By-person factor analysis, where participants are defined as variates, yielded information about the attitudinal background the physicians brought to their consideration of each hypothetical case. We performed a second-order factor analysis on all of the subjective viewpoints to determine if a smaller core of shared attitudes existed across some or all of the four case vignettes. Factor scores for each item and post-sort comments from interviews conducted individually with each respondent guided the interpretation of ethical perspective used by these respondents in making clinical decisions about the cases. Measurements and Main Results: Second-order factor analysis on seventeen viewpoints used by physicians in the four hypothetical urgent decision cases revealed three moderately correlated (r 2 < 40%) subjective core attitudinal guides used broadly among all the cases and among sixteen of the seventeen original factors. Across all the cases, our participants were guided in general by: (1) patient-focused beneficence, (2) a patient- and surrogate-focused perspective that includes risk avoidance, and (3) best interest of the patient guided by ethical values. Economic impact on the physician, expediency in resolution of the situation, and the expense of medical treatment were not found to be influential determinants in this study. Conclusions: Q sorting and by-person factor analysis are useful qualitative methodological tools to study the complex structure of subjective attitudes that influence physicians in making medical decisions. This study revealed the subjective viewpoints used by our physician participants as they made ethically challenging treatment decisions. The three second-order factors identified here are grounded in current bioethical values as well as the personal traits of physicians. The participants' decision methods appear to resemble casuistry more than principle-based decision making. Generalizability of results will require further studies. (shrink)

_The Research Review for School Leaders, Volume III_ is specifically designed as a practical resource for school leaders whose schedules preclude opportunities to locate and review key research on every issue they must address. It places comprehensive, current, and accessible reviews of educational research at their fingertips, and is organized to make the research and practices it summarizes useful to them in their professional endeavors. This is the third volume of the _Review._ Although the title has changed, its purpose and (...) substance is continuous with the work of the earlier volumes. The first _Annual Review of Research for School Leaders_ summarized research on the status of public schooling, interdisciplinary curriculum, and educational applications of computers. The second volume addressed the topics of middle-level education, the extracurriculum, mathematics education reform, and drop outs. The present _Volume III_ offers educational leaders reviews of research on five timely educational issues: * citizenship education; * multicultural education; * gifted and talented education; * classroom assessment; and * scheduling. A basic premise of this volume is that, to make sound decisions, professionals need to be up to date on current research related to the problems with which they grapple. A second premise is that research cannot simply be imposed in a formulaic way on a local setting; the nature of the particular problem to be solved will always bear upon the relevance of research to a specific context. Thus, this volume is envisioned as a helpful resource for school leaders as they engage in important discussions of the research with teachers, school board members, parents, and other interested parties as they collaboratively seek effective resolutions to local educational problems.

In this book William G. Lycan offers an epistemology of philosophy itself, a partial method for philosophical inquiry. The epistemology features three ultimate sources of justified philosophical belief. First, common sense, in a carefully restricted sense of the term-the sorts of contingentpropositions Moore defended against idealists and skeptics. Second, the deliverances of well confirmed science. Third and more fundamentally, intuitions about cases in a carefully specified sense of that term. The first half of On Evidence in Philosophy expounds a version (...) of Moore's method and applies it to each of several issues. This version is shown to resist all the standard objections to Moore; most of them do not even apply. It is argued, in Chapters 5 and 6, that philosophical method is far lesspowerful than most have taken it to be. In particular, deductive argument can accomplish very little, and hardly ever is an opposing position refuted except by common sense or by science. The final two chapters defend the evidential status of intuitions and the Goodmanian method of reflectiveequilibrium; it is argued that philosophy always and everywhere depends on them. The method is then set within a more general explanatory-coherentist epistemology, which is shown to resist standard forms of skepticism.In sum, William G. Lycan advocates a picture of philosophy as a very wide explanatory reflective equilibrium incorporating common sense, science, and our firmest intuitions on any topic-and nothing more, not ever.
