Direction of the embyro's head rotation is determined by asymmetrical expression of several genes (such as shh, Nodal, lefty, and FGF8) in Hensen's node. This genetically determined head-turning bias provides a base for light-aligned population lateralization in chicks, in which the direction of the lateralization is determined by genetic factors and the degree of the lateralization is determined by environmental factors.

23 out of the 364 s?tras of the Shorter Chinese Sa?yukt?gama and many more of the Longer Chinese Sa?yukt?gama have no known direct counterpart in P?li, Sanskrit or Tibetan. These s?tras are especially suitable to introduce common problems regarding the relationship of early Indian s?tras and their Chinese translation. While usually the existence of an Indian parallel helps researchers to narrow down the range of likely forms of names and words, in the absence of Indian versions our understanding of translations (...) and transcriptions becomes all the more conjectural.?gama texts without a P?li counterpart must also be suspected to be later additions to the collection and we have to deduce from form and content of the s?tra as well as its position in the collection, when, where and why the text came into being. The article introduces these problems as they appear in two BZA sutras, both of which are translated below. (shrink)

_Revisits Julia Kristeva's magnum opus on the fiftieth anniversary of its original publication to open up new paths of interdisciplinary inquiry._ In her 1974 _Revolution in Poetic Language_, Julia Kristeva resisted the abstract use of language, with its aim of totalization and finality, in all its colonizing and alienating forms. A major thinker and critic, Kristeva reappropriated Hegel's concepts of desire and negativity, in conjunction with the thought of Heidegger, Arendt, Freud, and Lacan, to revolt against modernity's culture of nihilism (...) and the West's inability to deal with loss. This collection celebrates the fiftieth anniversary of _Revolution in Poetic Language_ by revisiting Kristeva's oeuvre and establishing exciting new directions in Kristeva studies. Engaging with queer and transgender studies, disability studies, decolonial studies, and more, renowned and rising scholars plot continuities in-and push the boundaries of-Kristeva's thinking about loss, revolution, and revolt. The volume also includes two essays by Kristeva, translated into English for the first time here-"The Impossibility of Loss" (1988) and "Of What Use Are Poets in Times of Distress?" (2016). (shrink)

The object of this essay is to discuss Ludwig Wittgenstein's remarks inPhilosophical Investigationsand elsewhere in the posthumously published writings concerning the role of therapy in relation to philosophy. Wittgenstein's reflections seem to suggest that there is a kind of philosophy or mode of investigation targeting the philosophical grammar of language uses that gratuitously give rise to philosophical problems, and produce in many thinkers philosophical anxieties for which the proper therapy is intended to offer relief. Two possible objectives of later Wittgensteinian (...) therapy are proposed, for subjectivepsychologicalversus objectivesemanticsymptoms of ailments that a therapy might address for the sake of relieving philosophical anxieties. The psychological in its most plausible form is rejected, leaving only the semantic. Semantic therapy in the sense defined and developed is more general and long-lasting, and more in the spirit of Wittgenstein's project on a variety of levels. A semantic approach treats language rather than the thinking, language-using subject as the patient needing therapy, and directs its attention to the treatment of problems in language and the conceptual framework a language game use expresses in its philosophical grammar, rather than to soothing unhappy or socially ill-adjusted individual psychologies.

The Mohists may have been the first consequentialists on earth. Their most important principles are that right action is what benefits the world and that the underlying outlook for benefiting the world is inclusive care, whereby each person receives equal consideration. The early Mohists are clearly objective-list consequentialists, whereby benefiting the world amounts to promoting the most basic goods. Stephens argues that the later Mohists shift to a preference-satisfaction consequentialism whereby benefiting the world amounts to promoting what happens to please (...) individual people. Stephens argues that while the direct texts are ambiguous between an objective-list interpretation and a preference-satisfaction interpretation, the latter better explains later Mohist engagement with opponents. I argue that the direct texts actually preclude Stephens’ preference-satisfaction interpretation, which moreover has the later Mohists concede an implausible amount to their opponents. (shrink)

Advance directives convey consumers’ wishes about accepting or refusing future treatment if they become incompetent. They are designed to communicate a competent consumer’s perspective regarding the preferred treatment, should the consumer later become incompetent. There are associated ethical issues for health practitioners and this article considers the features that are relevant to nurses. In New Zealand, consumers have a legal right to use an advance directive that is not limited to life-prolonging care and includes general health procedures. Concerns may arise (...) regarding a consumer’s competence and the document’s validity. Nurses need to understand their legal and professional obligations to comply with an advance directive. What role does a nurse play and what questions arise for a nurse when advance directives are discussed with consumers? This article considers the cultural dimensions, legal boundaries, consumers’ and providers’ perspectives, and the medical and nursing positions in New Zealand. (shrink)

Predictive medicine presents opportunities to consider later life under conditions of illness, such as dementia. This paper examines how family caregivers (N = 27) assess the opportunity of prediction and early diagnosis of dementia for oneself based on their particular experience. Furthermore, it compares their attitudes with laypersons’ attitudes (N = 43) towards genetic testing of APOE. By this, we elaborate how much personal experience impacts anticipation and affects, but also moral attitudes towards predictive medicine. Differences in our settings do (...) not allow for direct comparison, so our analysis focuses on multiple similarities in the assessments of predictive (non-genetic vs. genetic) testing. Groups’ reasoning showed also differences influenced mainly by personal experience. Family caregivers addressed more responsibility towards family and had more hopes into medical treatments. To cope with the disease, they expressed expectations to start with medicine and care decisions as early as possible. Laypersons, however, stressed self-determination more and expressed worries about the influence of the pharmaceutical industry by referring to unnecessary medication and, implicitly, the medicalization of aging.

The Great Divide in metaphysical debates about laws of nature is between Humeans, who think that laws merely describe the distribution of matter, and non-Humeans, who think that laws govern it. The metaphysics can place demands on the proper formulations of physical theories. It is sometimes assumed that the governing view requires a fundamental / intrinsic direction of time: to govern, laws must be dynamical, producing later states of the world from earlier ones, in accord with the fundamental (...) class='Hi'>direction of time in the universe. In this paper, we propose a minimal primitivism about laws of nature (MinP) according to which there is no such requirement. On our view, laws govern by constraining the physical possibilities. Our view captures the essence of the governing view without taking on extraneous commitments about the direction of time or dynamic production. Moreover, as a version of primitivism, our view requires no reduction / analysis of laws in terms of universals, powers, or dispositions. Our view accommodates several potential candidates for fundamental laws, including the principle of least action, the Past Hypothesis, the Einstein equation of general relativity, and even controversial examples found in the Wheeler-Feynman theory of electrodynamics and retrocausal theories of quantum mechanics. By understanding governing as constraining, non-Humeans who accept MinP have the same freedom to contemplate a wide variety of candidate fundamental laws as Humeans do. (shrink)

The accuracy of proxies when they interpret advance directives or apply substituted decision-making criteria has been called into question. It therefore became important to know if the Andalusian Advance Directive Form (AADF) can help to increase the accuracy of proxies' predictions. The aim of this research was to compare the effect of the AADF on the accuracy of proxies' predictions about patients' preferences with that gained from informative and deliberative sessions about end-of-life decision making. A total of 171 pairs of (...) patients and their proxies were randomized to three groups. The control group's answers to the Life Sustaining Preferences Questionnaire (LSPQ) were compared with their proxies' answers to the same questionnaire. In one intervention group, the patients had already completed the AADF and given it to their proxies, who used it to guide their own answers to the LSPQ. In the second intervention (discussion) group, both patients and proxies attended two educative sessions guided by trained nurses and later filled in the LSPQ. Comparisons of accuracy and other variables showed a strong association with the discussion group. The findings show that promoting communication between patients and their proxies improves the accuracy of proxies' predictions much more than isolated use of the AADF form. (shrink)

Advance directives for psychiatric care are the subject of debate in a number of Western societies. By using psychiatric advance directives , it would be possible for mentally ill persons who are competent and with their disease in remission, and who want timely intervention in case of future mental crisis, to give prior authorisation to treatment at a later time when they are incompetent, have become non-compliant, and are refusing care. Thus the devastating consequences of recurrent psychosis could be minimised.Ulysses (...) contracts raise a number of ethical questions. In this article the central issues of concern and debate are discussed from a narrative perspective. Ulysses contracts are viewed as elements of an ongoing narrative in which patient and doctor try to make sense of and get a hold on the recurrent crises inherent in the patient's psychiatric condition.

Denenberg rightly stresses the importance of studying ethologically meaningful species-specific behavior in animals, and makes the interesting distinction between lateralization at an individual and at a population level. However, in the case of man, I believe Denenberg is wrong in arguing that lateralization in the individual increases with maturation. The overall evidence nowadays tends very much to the contrary. Moreover, with respect to a population, why should it become lateralized? If there is indeed an advantage for the individual in hemispheric (...) specialization, why should the direction of such specialization be so consistent across a majority of individuals, whether human or, as Denenberg points out, other members of the phylum? Is there an evolutionary advantage in most animals' sharing the same direction, or is it a necessary consequence of some other preexisting, more fundamental anatomical, biochemical, or physical property of the organism and its constituents? If the former, why are not all members of the species, rather than just a majority, lateralized in the same direction? (Or, to put it another way, what is the evolutionary advantage to the species or individual of dimorphism, of retaining a minority who polarize in theoppositedirection?) If the latter - i.e., if lateralization is a necessary consequence of some prior state - then there should not be any dimorphism, exceptions, or minority members, unless they are somehow disadvantaged in consequence. Indeed, there is some evidence of a cognitive deficit in sinistrals, though it is disputed (see Bradshaw 1980 for review), and others have even suggested that the species as a whole maybenefitin some way from such an uneven dimorphism (Levy 1974), but what evidence is there for such propositions with respect to rats, apes, monkeys, or chicks? This is an issue that should be addressed in any general model that includes laterality in animals. [See Corhallis & Morgan: “On the Biological Basis of Human Laterality”BBS1(2) 1978.]. (shrink)

Martin Heidegger was a central figure in 20th century Western philosophy. In evaluating his work from the perspective of the early 21st century it is clear that his influence crossed disciplinary lines. This work aims to address one area where Heidegger's thinking has had tremendous impact---theology. Specifically, Heidegger's later writings are selectively examined in order to determine the bearing they have on the issue of God. ;The route to God, in a strict confessional sense, is neither easy nor direct in (...) the Heideggerian corpus. As a result, the first methodological tack used throughout this study establishes Heidegger's abiding thematic interests. Only after appreciating the continuity and context of his work can tentative and cautious theological applications be made as the second methodological tack. This approach simultaneously upholds the integrity of Heidegger's thought and protects the theological discipline from speculative forays antithetical to its mission. The hope is that the later Heidegger will be seen as a productive and engaging dialogue partner for theology. His voice deepens theology's traditional discourse about God as well as challenges modes of expression that are exclusivistic and ineffectual in the postmodern era. ;The following structure exposes the outreach of the later Heideggerian oeuvre to theological thought regarding God. The first two chapters contextualize Heidegger. Chapter one situates Heidegger on the stage of Western philosophy with the distinction of having creatively raised the question of the meaning of Being to a new level of urgency. Chapter two identifies two formative influences from Heidegger's very early career---phenomenology and a course load involving religious topics. ;The third and fourth chapters make connections between the later texts and God. Chapter three introduces the importance of poetry and the dynamics of poetics. The venturesome poet inhabits the "between" and restores authentic human dwelling as measured against the Godhead. Chapter four further develops Holderlin's significance and introduces Nietzsche's importance for exposing the challenge of godlessness during the needy time: the gods have fled and God is dead. ;The Reprise recapitulates the salient themes presented and recommends promising areas for future research.

If one takes Heidegger at his word then his philosophy is about pursuing different "paths" of thought rather than defining a single set of truths. This volume gathers the work of an international group of scholars to present a range of ways in which Heidegger can be read and a diversity of styles in which his thought can be continued. Despite their many approaches to Heidegger, their hermeneutic orientation brings these scholars together. The essays span themes from the ontic to (...) the ontological, from the specific to the speculative. While the volume does not aim to present a comprehensive interpretation of Heidegger's later thought, it covers much of the terrain of his later thinking and presents new directions for how Heidegger should and should not be read today. Scholars of Heidegger's later thought will find rich and original readings that expand considerations of Heidegger's entire oeuvre. (shrink)

Social norms play an essential role in human interactions and the development of the evolution of human history. Extensive studies corroborate that compliance with social norms typically requires a punishment threat as almost always specific individuals have self-interests that tempt them to violate the norm. Neural imaging studies demonstrate that lateral orbitofrontal cortex and right dorsolateral prefrontal cortex (rDLPFC) are activated when individuals decide to increase social norm compliance when punishment is possible. Moreover, rDLPFC is affirmed to be involved (...) in social norm compliance with or without external punishment threats in a series of transcranial direct current stimulation (tDCS) research. However, these neuroscience studies are based on the ultimatum game in which the decision-making power between the proposer and the responder is unequal, and no studies support the causal relationship between rDLPFC and voluntary cooperative norms compliance among the equal decision-making power of subjects. Whether modulating the excitability of rDLPFC, which plays a role in norm compliance, alters the extent of compliance with voluntary cooperative norms under equal decision-making power and how norms from different types with asymmetric endowment influence compliance remain unknown. The present study aimed to provide evidence of a direct link between the neural and behavioral results through the application of tDCS over rDLPFC on compliance with voluntary cooperative norms under equal decision-making power. Results verified that activating rDLPFC altered voluntary cooperative norms compliance of all our participants and significant effect over different initial endowments was observed. The role of norm.own and norm.other in compliance was changed in the anodal treatment. Findings validate that enhancing the excitability of the rDLPFC using tDCS leads to high compliance in voluntary cooperation and this effect is specific to equal decision-making power rather than unequal decision-making power.

Time is directed, which is often thought to conflict with the fact that all laws in fundamental physics are symmetric under time reversal. This is however a confusion of two concepts. That time is directed is reflected in the asymmetry of the predicates ‘before’ and ‘after’. A reversal of the time parameter in physics, on the other hand, is a mere change of convention, from labelling later times with bigger numbers, to labelling them with decreasing numbers. Just as the directions (...) of axes in spatial coordinate systems are mere conventions, the direction of the time axis is a mere convention and it is a fundamental requirement that fundamental physics be invariant under changes of such conventions.We can in many cases easily decide which of two events occurred before the other one without having any time measuring device or any memory of these events. Many physical systems change state irreversibly, this is the basis for the asymmetry of the predicates ‘before’ and ‘after’.It is further shown that a universal direction of time does not require any universal clock undergoing irreversible changes. It suffice that there are a number of partly isolated physical systems, each existing for some time and undergoing irreversible changes. If they partly overlap in time we can construct a universal time parameter beginning with Big Bang. A universal time direction can thus be constructed without using the second law of thermodynamics.

Researchers have been interested in what retrieval process is responsible for overgeneral autobiographical memories (OGM) in depression. Previous cross-sectional studies demonstrated that, for negatively valenced cues, directly retrieved OGM, rather than generatively retrieved OGM, are associated with depression. However, longitudinal evidence of this relationship is still lacking and needs to be tested. We conducted a re-analysis of the online computerised memory specificity training (c-MeST) data to examine whether directly retrieved OGM for negative cues prospectively predicts high levels of depression 1 (...) month later. Participants who met the criteria of current major depressive disorders (N = 116; n = 58 in the c-MeST group and n = 58 in the control group) recalled autobiographical memories for positive and negative cues and judged each retrieval process (i.e. direct or generative). The results supported our prediction, and directly retrieved OGM for negative cues predicted high levels of depressive symptoms 1 month later even after controlling for the group effect, baseline depressive symptoms, executive functioning and rumination. Exploratory analysis showed that direct retrieval of specific memories prospectively predicted low levels of depression. These results support the theory that elevated accessibility of negatively valenced general memory representations is a vulnerability factor for depressive symptoms. (shrink)

Aid‐in‐dying laws in the United States have two important restrictions. First, only patients who are terminally ill, defined as having a prognosis of six months or less to live, qualify. Second, at the time the patients take the lethal medication, they must be competent to make medical decisions. This means that an advance directive requesting aid in dying for a later time when the patient lacks decision‐making capacity would be invalid. However, many people are more concerned about avoiding living into (...) severe dementia for years—a time when they will lack decision‐making capacity—than they are about preventing suffering or the loss of dignity or autonomy for a few months at the end of life.Gillian Bennett is an example of someone determined not to live into severe dementia. She opted for preemptive suicide in 2014, explaining why in a letter she posted online: “Every day I lose bits of myself, and it’s obvious that I am heading toward the state that all dementia patients eventually get to: not knowing who I am and requiring full‐time care.”A major problem with Bennett’s solution, however, is that the individual is likely thereby to be giving up some “good time.” A legal alternative to preemptive suicide is to create an advance directive stating the circumstances under which one wants not to receive any lifesaving or life‐sustaining treatment, even the most basic and noninvasive. This option is our focus in this paper: how to create effective advance directives to avoid living into severe dementia. To be relevant to progressive dementia, the directive would need to state what kinds of care should be withheld and when. At the same time, advance directives for severe dementia face serious challenges. Before addressing these, we review the normative force of directives themselves. (shrink)

I aim to clarify the moral authority of an advance directive that pertains to one’s later dementia-afflicted self. I develop the principle of Unity-Relative Autonomy, according to which the basis of self-governance is psychological unity rather than personal identity, and, on these grounds, argue that such advance directives have minimal weight grounded in respect for autonomy. I, nonetheless, suggest that bodily sovereignty should be distinguished sharply from autonomy, and maintain that one has a moral claim to decide the fate of (...) one’s later body. Lastly, I consider but reject the idea that such advance directives could have surrogate decision-making authority. (shrink)

This paper focuses on the inheritance of human handedness and cerebral lateralization within the more general context of structural biological asymmetries. The morphogenesis of asymmetrical structures, such as the heart in vertebrates, depends upon a complex interaction between information coded in the cytoplasm and in the genes, but the polarity of asymmetry seems to depend on the cytoplasmic rather than the genetic code. Indeed it is extremely difficult to find clear-cut examples in which thedirectionof an asymmetry is under genetic control. (...) As one possible case, there is some evidence that the direction, clockwise or counterclockwise, of rotation of the abdomen in certain mutant strains ofDrosophilais controlled by a particular gene locus, although there appears to be some degree of confusion on this point. By contrast, it is much easier to find examples in which thedegreebut not the direction of asymmetry is under genetic control. For instance, there is a mutant strain of mice in which half of the animals displaysitus inversusof the viscera. The proportion has remained at one half despite many years of inbreeding, suggesting that the mutant allele effectively cancels the normalsitusand allows the asymmetry to be specified in random fashion.Although this account does not deny that the right hemisphere of humans may be the more specialized for certain functions, it does attribute a leading or dominant role to the left hemisphere (at least in most individuals). We suggest that so-called “right-hemisphere” functions are essentially acquired by default, due to the left hemisphere's prior involvement with speech and skilled motor acts; we note, for instance, that these right-hemisphere functions include rather elementary perceptual processes. But perhaps the more critical prediction from our account is that the phenomenon of equipotentiality should be unidirectional: the right (lagging) hemisphere should be more disposed to take over left-hemisphere functions following early lesions than is the left (leading) hemisphere to take over right-hemisphere functions. We note preliminary evidence that this may be so. (shrink)

Schelling is best known in the Anglo-American philosophical community for work he did in his twenties, between 1797 and 1803. During this time, he appropriated Fichte’s standpoint of transcendental idealism and developed some of its implications for the philosophies of nature, history, and art. Schelling did not claim at this stage to be formulating an original standpoint of his own, but simply to be extending the Fichtean principles in new directions. In this endeavor he was quite successful, and for a (...) brief period he was lionized as philosophy’s youngest and brightest hope. He has been recognized since then as an important pioneer in the post-Kantian German idealist movement. (shrink)

It is a curious fact that many of the sources for the Presocratic and Stoic philosophers are early Christian authors; similarly, one can even find an echo of Parmenides in a Gnostic treatise from Nag Hammadi. Such writers were often dependent for their knowledge on a whole chain of previous interpretations and traditions, and it is these with which Professor Mansfeld is here largely concerned. He has tried to discover what in an earlier writer - Plato, and Aristotle, of course, (...) as well as the Early Greeks - was of interest to a later one, notably the Middle Platonists. These articles demonstrate the value of such an approach, showing how a familiarity with the later history of an idea, say in a Gnostic text, can contribute to the understanding of the idea itself; or how the study of the selection of ideas used by Philo, for instance, not only sheds light on his own projects, but also helps explain why some motifs survived and not others, and why philosophical thought took the directions it did.

Heralded as "the crowning work of a great career," Logic: The Theory of Inquiry was widely reviewed. To Evander Bradley McGilvary, the work assured Dewey "a place among the world's great logicians." William Gruen thought "No treatise on logic ever written has had as direct and vital an impact on social life as Dewey's will have." Paul Weiss called it "the source and inspiration of a new and powerful movement." Irwin Edman said of it, "Most philosophers write postscripts; Dewey has (...) made a program. His Logic is a new charter for liberal intelligence." Ernest Nagel called the Logic an impressive work. Its unique virtue is to bring fresh illumination to its subject by stressing the roles logical principles and concepts have in achieving the objectives of scientific inquiry.". (shrink)

Recent evidence in natural and semi-natural settings has revealed a variety of left-right perceptual asymmetries among vertebrates. These include preferential use of the left or right visual hemifield during activities such as searching for food, agonistic responses, or escape from predators in animals as different as fish, amphibians, reptiles, birds, and mammals. There are obvious disadvantages in showing such directional asymmetries because relevant stimuli may be located to the animal's left or right at random; there is no a priori association (...) between the meaning of a stimulus (e.g., its being a predator or a food item) and its being located to the animal's left or right. Moreover, other organisms (e.g., predators) could exploit the predictability of behavior that arises from population-level lateral biases. It might be argued that lateralization of function enhances cognitive capacity and efficiency of the brain, thus counteracting the ecological disadvantages of lateral biases in behavior. However, such an increase in brain efficiency could be obtained by each individual being lateralized without any need to align the direction of the asymmetry in the majority of the individuals of the population. Here we argue that the alignment of the direction of behavioral asymmetries at the population level arises as an “evolutionarily stable strategy” under “social” pressures occurring when individually asymmetrical organisms must coordinate their behavior with the behavior of other asymmetrical organisms of the same or different species. Key Words: asymmetry; brain evolution; brain lateralization; development; hemispheric specialization; laterality; lateralization of behavior; social behavior; theory of games. (shrink)

There are several models of the use of geometric and feature cues in reorientation. The adaptive combination approach posits that people integrate cues with weights that depend on cue salience and learning, or, when discrepancies are large, they choose between cues based on these variables. In a new paradigm designed to evaluate integration and choice, disoriented participants attempted to return to a heading direction, in a trapezoidal enclosure in which feature and geometric cues both unambiguously specified a heading, but (...) later the feature was moved. With discrepancies greater than 90 degrees, participants choose geometry. With smaller discrepancies, integration appeared in three of five situations; otherwise, participants used geometry alone. Variation depended on direction of feature movement and whether the nearest corner was acute or obtuse. The results have implications for contrasting adaptive combination and modularity theory, and for future research, offering a new paradigm for reorientation research, and for testing cue integration more broadly.

In his final and posthumously published work, The Visible and the Invisible, Maurice Merleau-Ponty employed the term "dehiscence" as a wonderful metaphor to describe our emergence within the world. This botanical term aptly calls to mind both the efflorescence of individuality within a shared context and the development of the practical implications of Merleau-Ponty's thought. The latter subject is the principal focus of the works collected in this book. Part One, a translation of three recently discovered letters between Jean-Paul Sartre (...) and Merleau-Ponty, provides a detailed record of the disagreement over political issues that ultimately drove the two philosophers apart. Part Two contains five essays devoted to the politcal implications of Merleau-Ponty's later thought; some scholars criticize the attempt to find practical political applications for this thought; others suggest how such a project might be accomplished. Part Three contains another five essays devoted to the ethical implications of these later texts. As in the previous section, some are critical assessments, others adumbrate the ways in which these insights might be successfully appropriated for such a praxis. This superb anthology addresses the critical need for material directly addressing the politics and ethics implied by Merleau-Ponty's later works. (shrink)

This book is a major contribution to the history of philosophy in the later medieval period (1250-1350). It focuses on cognitive theory, a subject of intense investigation during these years. In fact many of the issues that dominate philosophy of mind and epistemology today - intentionality, mental representation, scepticism, realism - were hotly debated in the later medieval period. The book offers a careful analysis of these debates, primarily through the work of Thomas Aquinas, John Olivi, and William Ockham. Each (...) of these figures attempts to reconceptualise cognition along direct realist lines, criticising in the process the standard Aristotelian account. Though of primary interest to medieval philosophers, the book presupposes no background knowledge of the medieval period, and will therefore interest a broader community of philosophers concerned with the origins of contemporary cognitive theory.

The early Frankfurt School’s Studies in Authority sought to understand modern society’s susceptibility to authoritarian leadership. This research project resulted in two major works in 1936, Fromm’s Studies on Authority and Family and Horkheimer’s Egoism and Freedom Movements, and produced the concept of the Authoritarian Character. After 1939 the project was abandoned, Fromm and the Frankfurt School went their separate ways, and the Frankfurt School’s research focus turned in a new direction. This paper argues that, appearances notwithstanding, research on (...) the Authoritarian Character did not end in 1939 and that Fromm’s later work on necrophilia and biophilia in the 1960s-70s should be reconsidered as his attempt to complete the Frankfurt School’s research project on the Authoritarian Character.

It seems that time has direction which points ahead from the past to the future. Traditionally, the main efforts to explain the arrow of time were carried out within the domain of physics, primarily utilizing statistical mechanics laws. Here, I attempt to explain how the forward direction of time is configured from the viewpoint of the mind. At first impression the concept of forward direction stems from the meeting of subjectivity with space and as such it is (...) applied to time. However, I show that the forward direction of time has a unique temporal sense not derived from space. Later I relate phenomenological explanations of the flow of time to the direction of time.

Wittgensteinian philosophy of religion has traditionally been grounded in non-cognitivism about religious belief. This paper shows that the Wittgensteinian tradition has wrongly neglected a significant movement towards cognitivism in Wittgenstein’s later writings. The argument proceeds on the basis of two main claims. First, Wittgenstein’s mature philosophy, as expressed in his _Philosophical Investigations_, clearly favours cognitivism over non-cognitivism with regard to certain linguistic facts about ordinary religious discourse. Second, during the last decade of his life Wittgenstein’s view of religious belief actually (...) underwent a significant shift in the direction of cognitivism, which finds its most striking expression in the analogy he draws to the ‘honest religious thinker’.

This paper pursues three goals: First, to develop a lateral reading of Camus’ Stranger. A lateral reading is characterized by the displacement of the central conflict. In the case of The Stranger, I argue that the central conflict in the novel lies in the relation between the author and the protagonist, not, as direct readings would have it, in the relation between the protagonist and his predicament. Second, to spell out more precisely why it should be read as (...) an anti-existentialist novel. Here I argue that a lateral reading shows that the foundational existentialist opposition between telling and living is ironically dismantled by the very lateral structure of the novel. Third, to develop the notion of a lateral reading with a view to its potential advantages. Here, I point out that literalism involves positionalism and dynamicism. Positionalism refers to the reduction of fictional entities to their role in relation to each other. Dynamicism refers to the resulting view that those roles are further reducible to forces. I conclude that the lateral reading, with its commitments to positionalism and dynamicism is a model generalizable to the analysis of other fictional works. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:BOOK REVIEWS 533 Grammar of Assent. Yet whereas Reid had urged a fundamental agree· ment on first principles on the intuitive basis of common sense, Newman thought such principles were discovered inductively and that there might he much disagreement. It was the disagreement itself that led to the need for a better understanding of the reasoning process. In place of common sense, Newman appealed to the illative sense. In (...) l:his regard, Newman directly rejeots Locke's distinction between demon· stration and probability. Various kinds of probabilistic reasoning for Newman can lead to a certainty beyond reasonable doubt. Ferreira claims that in this regard Newman is following a strategy not unlike l:hat of Reid. Both Reid's common sense and Newman's illative sense are natural. However, the former can discover only self-evident 'truths while the latter is part of the process of reasoning itself. Ferreira pro· vides a very full discussion of the manner in which these outlooks led Newman into the tradition of a naturalistic response to scepticism. Both philosophers and intellectual historians will find Professor Ferreira's volume useful and informative. In a very sprightly man· ner she has explored a tradition of British intellectual life that often has remained ignored. She has displayed very considerable daring in attempting to cover two centuries of thought. The most valuable sec· tions are no doubt those on Reid and Newman where she has care· fully illuminated a major intelleotual path not.taken hy most late nine· teenth· and twentieth-century British philosophers hut which exerted very considerable influence during the first three-quarters of rthe nine· teenth century. The volume also prepares the way for intellectual his· torians to examine what were the social and struotural reasons within British intellectual life for these particular anti-sceptical strategies. FRANK M. TURNER Yale University New Haven, Connecticut The Later Wittgenstein: The Emergence of a New Philosophical Meth· od. By S. STEPHEN HILMY. Oxford: Basil Blackwell, 1987. Pp. viii+ 340. This is a hook of extraordinary scholarly density. Its 226 pages of text are complemented hy 94 pages of notes, 6 pages of bibliography, and 14 pages of indices. A heavy texture of relentlessly documented argument, Hilmy's hook is neither for philosophical novices nor for!:hose whose interest in Wittgenstein is merely moderate. To profit from 534 BOOK REVIEWS this hook, the reader must share the intense concern that led the author to plough through Wittgenstein's vast Nachlass. But readers must also he willing to contend with a style of writing that is often forbiddingly and needlessly convoluted, and with a tone that is sometimes snide. More will he said about these problems below, after a discussion of the hook's purposes. Hilmy believes Wittgenstein scholarship to he in a sorry state. The problem stems, he thinks, from blunders committed hy the literary executors. He writes, " The unhappy state of Wittgenstein scholarship is in large part due to the fragmented and ahistorical character of the potpourri of published remarks wirth which scholars have been work· ing" (viii). Indeed, his confidence in the published materials is so low that he often refers to them as Wittgenstein's "works" (in quotation marks) to signal his disdain for the editors' selections and arrange· ments. The scope of this volume is intentionally limited; little or no assess· ment of Wittgenstein's conclusions is offered. But Hilmy does claim to he taking a necessary first step which, he says, "much of the volumin· ous literature... has dismally failed to take" (3); namely, an examination of.the historical development of Wittgenstein's later way of thinking (Denkweise) as chronicled in the Nachlass. His appeal to the manuscript material is based on his belief that rthe "conglomerated fragments" (9) in the published works are best understood in their original contexts and in light of later contexts into which Wittgenstein placed them in the process of revision. Much of the stylistic character of Hilmy's hook stems from.the necessarily laborious nature of trac· ing these origins and transpositions, and from his sense of getting Witt· genstein right for the first time. After sorting through some preliminary issues concerning Wittgenstein 's compositional style, Hilmy produces an... (shrink)

In 1971, priest, theologian, and philosopher Ivan Illich wrote Deschooling Society, a plea to liberate education from schooling and to separate schooling from the state. On occasion of the fiftieth anniversary of its publication, Ivan Illich Fifty Years Later looks at the theological roots of Illich's thought and the intellectual and ideological strands that contributed to his ideas. Guided by the central question of how Illich reached the point of writing Deschooling Society, the book sheds light on how Illich produced (...) a critique of schooling that can be defined by its eclecticism. Bruno-Jofré and Igelmo Zaldívar explore how this controversial book was framed by Illich's early neo-scholastic and anti-modern foundation, his discovery of St. Thomas through Jacques Maritain, and the existential turning points that influenced his public life and intellectual direction in moving from a critique of the Church as institution to a critique of schooling. Drawing from the interpretative theories of Quentin Skinner, Reinhart Koselleck, and William H. Sewell and from concepts such as educationalization, transnationality, and configuration, among other heuristic tools, the authors provide an original and cross-disciplinary analysis of Deschooling Society and its place in Illich's journey.

Human molars from travertine deposits of Witkrans Cave (Gaap Escarpment, northern Cape Province, South Africa) are described. The Witkrans molars were discovered in direct association with later Pleistocene faunal remains and a sample of Middle Stone Age artifacts (Peabody, 1954; Clark, 1971; Sampson, 1974; Klein, 1984; Volman, 1984). The morphology and dimensions of the Witkrans molars resemble remains from other localities of similar age in southern Africa (Singer & Wymer, 1982; Grine & Klein, 1985; Grine et al., 1991; Rightmire & (...) Deacon 1991) but exhibit differences from later Pleistocene occurrences in northern Africa (McBurney et al. 1953; Vallois & Roche, 1958; Ennouchi, 1969; Hublin & Tillier, 1981). These results offer further support for the existence of later Pleistocene human populations south of the Sahara which were distinct from contemporaneous peoples of Mediterranean Africa (Howell, 1978; Brauer, 1984; Rightmire, 1984; Klein 1992).

The author explores various pedagogical methods concerning how to teach Wittgenstein’s later work. A significant obstacle for the incorporation of Wittgenstein into an undergraduate curriculum is to decipher the major features of his philosophical ideas. The engagement with Wittgenstein’s work is not a task of mere comprehension or thought, but rather of discernment and observation of the ways language operates in the formulation of ideas. The distinction between observation and thought in Wittgenstein’s work on language is often overlooked. In order (...) to teach Wittgenstein effectively, the curriculum should focus on various methods to teach students not just to think but to observe. The author offers a series of classroom exercises and games to engage students with the text and to elucidate philosophical components necessary to understand the author. The games direct students’ attention to what they need to notice and observe in the function of language in Wittgenstein’s later work. (shrink)

We compare a “Mach-Zehnder interferometer in time” for cold neutrons with its well-known spatial counterpart and demonstrate the intimate connection between space and time for both setups. Further, we outline a combined space-time interferometer, which coherently splits a wavepacket in longitudinal and lateral direction. On the way towards time interferometry “neutron computer holography” seems to be an attractive application. It allows the three-dimensional reconstruction of an object from the scattered intensity, but in contrast to holography with light, there (...) is no need for a reference wave. On the other hand, the possible resolution is worse than in the light case. (shrink)

In later Yogācāra, the path to enlightenment is the course of learning the Four Noble Truths, investigating their meaning, and realizing them directly and experientially through meditative practice (bhāvanā). The object of the yogi’s enlightenment-realization is dharma and dharmin: The dharma is the true nature of real things, e.g., momentariness, while the dharmin is real things i.e., momentary things. During the practice of meditation, dharma is directly grasped in the process of clear manifestation (viśadābhā) and the particular dharmin is indirectly (...) ascertained in the process of determination (adhyavasāya). So, even though a yogi does not directly perceive any actual thing, s/he is still nonetheless able to undertake practical activity directed toward it. The realization of the Four Noble Truths consists of two aspects: firstly, the manifestation of momentariness, etc., in the stream of the yogi’s consciousness; secondly, the ascertainment of momentariness, etc., in whatever s/he happens to encounter.

Many people are worried about developing dementia, fearing the losses and burdens that accompany the condition. Dementia‐specific advance directives are intended to address dementia's progressive effects, allowing individuals to express their treatment preferences for different stages of the condition. But enthusiasm for dementia‐specific advance directives should be tempered by recognition of the legal, ethical, and practical issues they raise. Dementia‐specific advance directives are a simplistic response to a complicated situation. Although they enable people to register their future care preferences, in (...) many cases, those preferences will not, and should not, determine their later care. (shrink)

The lateral line system of fish and amphibians is closely related to the inner ear in terms of evolution, morphology and physiology. Several recent papers have shed new light on the postembryonic development of this system, and have revealed an unexpected triangular relationship where migrating sensory precursors guide axons, axons guide glia and glia, in turn, control the formation of sensory organs. They have also revealed the crucial importance of controlled cell migration not only for patterning the system, but (...) also for determining polarity (and therefore directional sensitivity) of the mechanosensory hair cells. The remarkable accessibility of the lateral line system may allow a detailed analysis of cell migration and polarization, and may help us better understand the complex interactions between sensory precursor cells, neurons and glia during development.

Advance directives are written documents that give patients the opportunity to communicate their preferences regarding treatments they do or do not want to receive in case they become unable to make decisions. Commonly used pre-printed forms have different formats. Some offer space for patients to appoint a surrogate decision maker, and/or to determine future medical treatments and/or give a statement of personal values. So far it is unknown which forms GPs preferably use and why they decide to do so. 23 (...) semi-structured interviews with GPs were analysed using content analysis. Interviewees mainly use short templates and medium length templates with checkboxes to indicate patients’ preferences in regards to life prolonging measures. Especially when patients faced the progression of a disease, participants use the latter version. Only then, the interviewees remarked, patients are capable to rate concrete situations reliably. GPs also realize the importance of the verbal assessment of patients’ preferences; however they rarely keep a written form of the conversation. Some GPs hand out one or more templates and ask their patients to read and think about them at home with the option to talk to them about it later on, while others prefer their patients to fill them out alone at home. Regardless of template usage, most GPs emphasize that ADs require regular updates. GPs tend to see standardized advance directives mainly as a tool to start a conversation with their patients and to identify their real preferences and values. When the patient is still not facing the progression of an already existing disease it could be sufficient to only appoint a surrogate decision maker instead of creating a full AD. However, in all other situations, appointing a surrogate decision maker should be backed up by a written statement of a patient’s general values. Patients and their relatives should always have the opportunity to ask their GP for medical advice when drafting an AD. It is crucial to regularly verify and update existing ADs within the course of a disease. (shrink)

The physical possibility of spacetimes containing closed timelike curves (CTCs) challenges the philosophy of time in the way that temporal ordering is, at best, remarkably non-standard: events on CTCs precede themselves. Apparently, such universes do not possess a consistent time order but only a consistent time direction. Thus, temporal directionality seems to be more fundamental than ordering in earlier-later or past-present-future. I will argue that this favors presentism as the adequate ontology of spacetimes: only presentism consistently copes with the (...) idea that temporal ordering depends on empirical constraints. The presentist Now is fundamentally undivided and productively directed towards existence. Time order arises by extending the Now, which can fail and in fact fails in universes containing CTCs.

Introduction People with Amyotrophic Lateral Sclerosis (ALS) are commonly cared for at home and receive palliative care relatively late. Caregivers are therefore left to navigate complex ethical decisions without professional support. This qualitative study explores the ethical dilemmas encountered by bereaved caregivers during their loved one's illness. Methods We conducted a qualitative dialogic co-constructed exploration following the theory of social constructivism. Reflexive thematic analysis was used to analyze interviews with bereaved caregivers from the'Homecare ALS'pilot project. Results Three key themes (...) contributing to caregivers’ (n = 16) ethical dilemmas were identified: (1) Being alone with the responsibility as the main coordinator of care; (2) Preserving the patient's autonomy as the disease progresses and (3) Changes in therapy directives and application of pro-re-nata (PRN) medication. Discussion Balancing beneficence, non-maleficence and autonomy as the disease progresses are complex tasks. Decisions surrounding end-of-life care, communication challenges, and medication management can cause moral dilemmas. To prevent moral distress in ALS caregivers, comprehensive support systems, including neuropalliative care, timely communication, and coaching in medication management are needed. Proactive care planning and emotional support for caregivers are essential to address ethical challenges and ensure a peaceful and dignified end of life for people with ALS. (shrink)

Bioethicists are widely agreed that patients have a right of self-determination over how they are treated. Our duty to respect this is said to be based on the principle of respect for autonomy. In end-of-life care the patient may be incompetent and unable to exercise that right. One solution is to exercise it in advance. Advance directives, which include living wills and powers of attorney for health care, enable people to decide what medical treatment they will receive later, when they (...) become incompetent. Advance directives have been criticized in two general ways. First, many critics contend that advance directives fail on a practical level to effect a patient's autonomous choices because, for example, people cannot foresee their futures well enough to make informed decisions in advance. Second, many critics contend that, practical problems aside, there is no moral authority for exercising control over one's incompetent future self. (shrink)

Here we studied how participants steer to intercept uniformly moving targets in a virtual driving task. We tested the hypothesis that locomotor interception behavior cannot fully be explained by a strategy of nulling rate of change in pertinent agent-target relations such as the target-heading angle or target’s bearing angle. In line with a previously reported observation and model simulations, we found that, under specific combinations of initial target eccentricity and target motion direction, locomotor paths revealed reversals in movement (...) class='Hi'>direction. This phenomenon is not compatible with unique reliance on first-order information in the case of uniformly moving targets. We also found that, as expected, such reversals in movement direction were not observed consistently over all trials of the same experimental condition: their presence depended on the timing of the first steering action effected by the participant, with only early steering actions leading to reversals in movement direction. These particular characteristics of the direction-reversal phenomenon demonstrated here for a locomotor interception-by-steering task correspond to those reported for lateral manual interception. Together, these findings suggest that control strategies operating in manual and locomotor interception may at least share certain characteristics. (shrink)

Humans are strongly lateralized for manual gestures at both individual and population levels. In contrast, the laterality bias in primates is less strong, leading some to suggest that lateralization evolved after the Pan and Homo lineages diverged. However, laterality in humans is also context-dependent, suggesting that observed differences in lateralization between primates and humans may be related to external factors such as the complexity of the social environment. Here we address this question in wild chimpanzees and examine the extent to (...) which the laterality of manual gestures is associated with social complexity. Right-handed gestures were more strongly associated with goal-directed communication such as repair through elaboration in response to communication failure than left-handed gestures. Right-handed gestures occurred in evolutionarily urgent contexts such as in interactions with central individuals in the network, including grooming reciprocity and mating, whereas left-handed gestures occurred in less-urgent contexts, such as travel and play. Right-handed gestures occurred in smaller parties and in the absence of social competition relative to left-handed gestures. Right-handed gestures increased the rate of activities indicating high physiological arousal in the recipient, whereas left-handed gestures reduced it. This shows that right- and left-handed gestures differ in cognitive and social complexity, with right-handed gestures facilitating more complex interactions in simpler social settings, whereas left-handed gestures facilitate more rewarding interactions in complex social settings. Differences in laterality between other primates and humans are likely to be driven by differences in the complexity of both the cognitive skills underpinning social interactions and the social environment.

Reputation is a key component in social interactions of group-living animals and appears to play a role in the establishment of cooperation. Animals can form a reputation of an individual by directly interacting with them or by observing them interact with a third party, i.e., eavesdropping. Elephants are an interesting taxon in which to investigate eavesdropping as they are highly cooperative, large-brained, long-lived terrestrial mammals with a complex social organisation. The aim of this study was to investigate whether captive Asian (...) elephants could form reputations of humans through indirect and/or direct experience in two different paradigms: a cooperative string-pulling task and a scenario requiring begging. Fourteen captive Asian elephants in Thailand participated in an experimental procedure that consisted of three parts: baseline, observation, and testing. In the observation phase, the subject saw a conspecific interact with two people—one cooperative/generous and one non-cooperative/selfish. The observer could then choose which person to approach in the test phase. The elephants were tested in a second session 2–5 days later. We found no support for the hypothesis that elephants can form reputations of humans through indirect or direct experience, but these results may be due to challenges with experimental design rather than a lack of capacity. We discuss how the results may be due to a potential lack of ecological validity in this study and the difficulty of assessing motivation and attentiveness in elephants. Furthermore, we highlight the importance of designing future experiments that account for the elephants' use of multimodal sensory information in their decision-making. (shrink)

The point of Wittgenstein’s remarks on colour concerns, not so much colours as such, as well as our ability to see [that implies both seeing ánd thinking] and our capacity to imagine something. This can be seen from the fact that Wittgenstein relates the notion of ‘seeing aspects’ on the one hand to the colour octahedron in PB, and on the other hand to the colour puzzles as discussed in ROC. This connection between Wittgenstein’s remarks on colour, on seeing aspects (...) and on certainty makes clear that these investigations of Wittgenstein direct us towards a reflective dynamics of his ideas.

In a single short passage in "On Sense and Reference" Frege outlines his conception of direct quotation wherein words must not be taken as having their customary reference, but rather refer to the words themselves or the words of another speaker. What unifies these uses? What is the logical form of direct quotation sentences, and what is their analysis? How does this view fit in with Frege's general semantics? How far can it be extended? What problems does it face? We (...) explore, if not completely answer, each of these questions."It can also happen, however, that one wishes to talk about the words themselves or their sense. This happens, for instance, when the words of another are quoted. One's own words then first designate words of the other speaker, and only the latter have their usual reference. We then have signs of signs. In writing, the words are in this case enclosed in quotation marks. Accordingly, a word standing between quotation marks must not be taken as having its ordinary reference," ("On Sense and Reference", 144)The above quotation contains virtually everything Frege has to say about quotation and it raises a number of issues --some terminological, some substantive. First, note that in the passage cited, Frege opens with a discussion of quotation in general ("talk about"), then ends with the specific case of quotation marks in writing. Most discussions of Frege have concentrated on quotation marks in writing, and we shall do so here, but ultimately a Fregean account will have to be more general, a point we will return to later. Second, Frege speaks of words enclosed in quotation marks as about "the words themselves" and also as about "words of another speaker". But as we will see, these need not be the same. However, because Frege moved so easily between them he may have thought that referring to the words themselves is involved in reporting the words of another speaker. At least this is an idea we will exploit later, but first some terminology. (shrink)
