Evolution fuels interindividual variability in neuroplasticity, reflected in brain anatomy and functional connectivity of the expanding neocortical regions subserving reading ability. Such variability is orchestrated by an evolutionarily conserved, competitive balance between epigenetic, stress-induced, and cognitive-growth gene expression programs. An evolutionary developmental model of dyslexia, suggests that prenatal and childhood subclinical stress becomes a risk factor for dyslexia when physiological adaptations to stress promoting adaptive fitness, may attenuate neuroplasticity in the brain regions recruited for reading. Stress has the potential to (...) blunt the cognitive-growth functions of the predominantly right hemisphere Ventral and Dorsal attention networks, which are primed with high entropic levels of synaptic plasticity, and are critical for acquiring beginning reading skills. The attentional networks, in collaboration with the stress-responsive Default Mode network, modulate the entrainment and processing of the low frequency auditory oscillations and visuospatial orienting linked etiologically to dyslexia. Thus, dyslexia may result from positive, but costly adaptations to stress system dysregulation: protective measures that reset the stress/growth balance of processing to favor the Default Mode network, compromising development of the attentional networks. Such a normal-variability conceptualization of dyslexia is at odds with the frequent assumption that dyslexia results from a neurological abnormality. To put the normal-variability model in the broader perspective of the state of the field, a traditional evolutionary account of dyslexia is presented to stimulate discussion of the scientific merits of the two approaches.

Posner [6] has shown, by a nonuniform proof, that every ▵ 0 2 degree has a complement below 0'. We show that a 1-generic complement for each ▵ 0 2 set of degree between 0 and 0' can be found uniformly. Moreover, the methods just as easily can be used to produce a complement whose jump has the degree of any real recursively enumerable in and above $\varnothing'$ . In the second half of the paper, we show that the complementation (...) of the degrees below 0' does not extend to all recursively enumerable degrees. Namely, there is a pair of recursively enumerable degrees a above b such that no degree strictly below a joins b above a. (This result is independently due to S. B. Cooper.) We end with some open problems. (shrink)

Perturbations of quantum systems ranging from oscillators to fields can be either continuous or discontinuous functions of the coupling. The system under consideration is the familiar harmonic oscillator in one degree of freedom. Previous studies have shown that when the harmonic oscillator is subjected to a perturbation with a power law singularity, a permanent change in the system characteristics is observed for a specific range of power law values. The introduction of a logarithmic singularity into the power law potential fine (...) tunes the singularity power. (shrink)

This paper addresses what some view as a progressive and decades-long devaluing of the liberal arts in our educational institutions and society at large. It draws attention to symptoms of this trend and possible contributing factors, identifies benefits commonly attributed to the liberal arts, and then shows how insights from recent research on neuroplasticity provide good reason to believe that a traditional liberal education has positive effects on a person's brain. The paper supports the thesis that well-designed liberal arts courses (...) can literally transform students' minds and lives as a result of unique and synergistic brain processes activated and strengthened by the leaming experiences such courses provide. It finishes with recommendations to help reinvigorate and promote the value of liberal education. (shrink)

Constructive engagement in international business practice is defined as purpose-driven behavior in which economic contributions by the foreign investor also advance social progress in the host country. This paper distinguishes between amoral and moral social agency, and proposes a model of principled constructive engagement that describes a principled constructive engagement regime enacted in a disciplined, morally-directed manner.

Responsibility for the protection of human research subjects is shared by investigators, research ethics committees, sponsors/funders, research institutions, governments and, the focus of this article, physicians who enrol patients in clinical trials. The article describes the general principles of the patient-physician relationship that should regulate the participation of physicians in clinical trials and proposes guidelines for determining when and how such participation should proceed. The guidelines deal with the following stages of the trial: when first considering participation, when deciding whether (...) to enrol patients, when asking patients to participate, when the trial is underway and when it is completed.

As Louisiana and Cuba emerged from slavery in the late nineteenth century, each faced the question of what rights former slaves could claim. Degrees of Freedom compares and contrasts these two societies in which slavery was destroyed by war, and citizenship was redefined through social and political upheaval. Both Louisiana and Cuba were rich in sugar plantations that depended on an enslaved labor force. After abolition, on both sides of the Gulf of Mexico, ordinary people-cane cutters and cigar workers, laundresses (...) and labor organizers-forged alliances to protect and expand the freedoms they had won. But by the beginning of the twentieth century, Louisiana and Cuba diverged sharply in the meanings attributed to race and color in public life, and in the boundaries placed on citizenship. Louisiana had taken the path of disenfranchisement and state-mandated racial segregation; Cuba had enacted universal manhood suffrage and had seen the emergence of a transracial conception of the nation. What might explain these differences? Moving through the cane fields, small farms, and cities of Louisiana and Cuba, Rebecca Scott skillfully observes the people, places, legislation, and leadership that shaped how these societies adjusted to the abolition of slavery. The two distinctive worlds also come together, as Cuban exiles take refuge in New Orleans in the 1880s, and black soldiers from Louisiana garrison small towns in eastern Cuba during the 1899 U.S. military occupation. Crafting her narrative from the words and deeds of the actors themselves, Scott brings to life the historical drama of race and citizenship in postemancipation societies. (shrink)

Comments on:Charles T. Mathewes, Agency, Nature, Transcendence, and Moralism: A Review of Recent Work in Moral Psychology.

My work in the philosophy of mind developed out of my early work in the philosophy of language, especially the theory of speech acts, Most of my work in the philosophy of mind has been concerned with the topics of intent ion ality and its structure, particularly the intentionality of perception and action and the relation of the intentionality of the mind to the intentionality of language. I have also written extensively on cognitive science (see cognitive psychology), especially on the (...) limitations Of the COMPUTATIONAL MODEL of the mind. Other work has concerned the mind‐body problem, the nature and structure of consciousness, the relation of consciousness to unconsciousness, the proper form of explanation in the social sciences and in the explanation of human behaviour generally, and the background of intentionality. I can only discuss a small number of these topics in this article, so I will confine myself to four of the most controversial areas. (shrink)

The title of The Rediscovery of the Mind suggests the question "When was the mind lost?" Since most people may not be aware that it ever was lost, we must also then ask "Who lost it?" It was lost, of course, only by philosophers, by certain philosophers. This passed unnoticed by society at large. The "rediscovery" is also likely to pass unnoticed. But has the mind been rediscovered by the same philosophers who "lost" it? Probably not. John Searle is (...) an analytic philosopher, with some of the same notions as the positivists and behaviorists who rejected consciousness and "lost" the mind in the first place, but he also does not sound like the kind of reductionist who would have joined that crowd. His views, indeed, are sensible enough, and some of his insights so important, that it is a shame to find his thought profoundly limited by some of the same mistakes and prejudices that ruined philosophy, and not just philosophy of mind, under the influence of those positivists and behaviorists. There is enough of genuine value in his treatment, that it can easily be taken up and, with relatively slight modification, added to what is of permanent value in the history of philosophy. (shrink)

By John R. Searle Copyright John R. Searle I. Naturalizing Language I believe that the greatest achievements in philosophy over the past hundred or one hundred and twenty five years have been in the philosophy of language. Beginning with Frege, who invented the subject, and continuing through Russell, Wittgenstein, Quine, Austin and their successors, right to the present day, there is no branch of philosophy with so much high quality work as the philosophy of language. In my view, (...) the only achievement comparable to those of the great philosophers of language is Rawls’s reinvention of the subject of political philosophy (and therefore implicitly the subject of ethics). But with this one possible exception, I think that work in the philosophy of language is at the top of our achievements. Having said that, however, I have to record a serious misgiving I have about the subject. The problem is that its practitioners in general do not treat language as a natural phenomenon. This may seem a strange charge to make, given that so many contemporary and recent philosophers of language are anxious to emphasize the empirical character of their theories of language. Quine and Davidson are striking examples of resolute empiricism. My objection is that few contemporary and recent philosophers of language attempt to treat language as a natural extension of non-linguistic biological capacities. Language is not seen as continuous with, nor as an extension of, the rest of our specifically human biological inheritance. I think there is a deep reason, both historically and intellectually, why language has not been treated naturalistically. It is.. (shrink)

The dispute between the empiricist and interpretivist conceptions of the social sciences is properly conceived not as a matter of reduction or covering laws. Features specific to the social sciences include the following. Explanations of human behavior make reference to intentional causation; social phenomena are permeated with mental components and are self-referential; social science explanations have not been as successful as those in natural science because of their concern with intentional causation, because their explanations must be identical with the propositional (...) content of the mind of the actor, and because a social phenomenon exists only if people believe it exists. Elements of an apparatus necessary to analyze this problematic social ontology are given and include selfreferentiality, constitutive rules, collective intentionality, linguistic permeation of the facts, systematic interrelationships among social facts, and primacy of acts over objects.

The study of rationality and practical reason, or rationality in action, has been central to Western intellectual culture. In this invigorating book, John Searle lays out six claims of what he calls the Classical Model of rationality and shows why they are false. He then presents an alternative theory of the role of rationality in thought and action. A central point of Searle's theory is that only irrational actions are directly caused by beliefs and desires—for example, the actions of (...) a person in the grip of an obsession or addiction. In most cases of rational action, there is a gap between the motivating desire and the actual decision making. The traditional name for this gap is "freedom of the will." According to Searle, all rational activity presupposes free will. For rationality is possible only where one has a choice among various rational as well as irrational options. Unlike many philosophical tracts, Rationality in Action invites the reader to apply the author's ideas to everyday life. Searle shows, for example, that contrary to the traditional philosophical view, weakness of will is very common. He also points out the absurdity of the claim that rational decision making always starts from a consistent set of desires. Rational decision making, he argues, is often about choosing between conflicting reasons for action. In fact, humans are distinguished by their ability to be rationally motivated by desire-independent reasons for action. Extending his theory of rationality to the self, Searle shows how rational deliberation presupposes an irreducible notion of the self. He also reveals the idea of free will to be essentially a thesis of how the brain works. (shrink)

This book is the first interlinear bilingual edition of the core Inner Chapters of the book Zhuangzi, which must be counted among the most famous texts in Chinese intellectual and literary history. A special feature of this edition is that it follows the specific rhythm and rhyme of the text in the translation, making it possible to experience the particular style of this most exciting of the ancient Chinese philosophers. -/- An extensive introduction explains the history and the literary nature (...) of the text, and in particular it tells the story of how this text was appreciated and commented upon in China and translated into foreign languages through the ages. Extensive footnotes are provided to enable Western readers to read the text through the eyes of the enthusiastic Chinese commentators who have annotated the text over the centuries: traditional Chinese literary as well as philosophical commentaries are presented in detail in the original classical Chinese and in translation. -/- For the general reader this book will offer a rare opportunity to approach one of the most outrageously unconventional texts of world literature with the philosophical and philological perspectives of the greatest of its literate Chinese connoisseurs. For the student of Chinese this book will serve as a bilingual cornucopia of spirited classical Chinese discourse on a fiercely contested and always controversially discussed crucial text in the Daoist tradition of ancient China.

The present article presents Wang Fuzhi 王夫之 (1619-1692 C.E.)’s reading of the eighteenth chapter of the Zhuang-Zi 莊子 (ZZ) by looking at his entry from Zhuang-Zi-Tong 莊子通 and other key glosses from Zhuang-Zi-Jie 莊子解. The philosophical upshot, I aim to show, is that Wang takes ZZ as presenting the consummation of “the greatest joyousness” (zhi-le 至樂) as requiring getting rid of joyousness as one’s desideratum. Using Derek Parfit’s work as a point of reference, I aim to show that this is (...) not paradoxical or even inconsistent or even (directly or indirectly) self-defeating but is instead an interesting instance of a self-effacing theory.
