Central to contemporary cognitive science is the notion that mental processes involve computations defined over internal representations. This view stands in sharp contrast to the to visual perception and cognition, whose most prominent proponent has been J.J. Gibson. In the direct theory, perception does not involve computations of any sort; it is the result of the direct pickup of available information. The publication of Gibson's recent book (Gibson 1979) offers an opportunity to examine his approach, and, more (...) generally, to contrast the theory of direct perception with the computational/representational view. In the first part of the present article (Sections 2direct perceptioncase study”: the problem of perceiving the three-dimensional shape of moving objects is examined. This problem, which has been extensively studied within the immediate perception framework, serves to illustrate some of the inherent shortcomings of that approach. Finally, in Section 5, an attempt is made to place the theory of direct perception in perspective by embedding it in a more comprehensive framework. (shrink)

Zipf famously stated that, if natural language lexicons are structured for efficient communication, the words that are used the most frequently should require the least effort. This observation explains the famous finding that the most frequent words in a language tend to be short. A related prediction is that, even within words of the same length, the most frequent word forms should be the ones that are easiest to produce and understand. Using orthographics as a proxy for phonetics, we test (...) this hypothesis using corpora of 96 languages from Wikipedia. We find that, across a variety of languages and language families and controlling for length, the most frequent forms in a language tend to be more orthographically well‐formed and have more orthographic neighbors than less frequent forms. We interpret this result as evidence that lexicons are structured by language usage pressures to facilitate efficient communication. (shrink)

Monothematic delusions are delusions whose contents pertain to a single subject matter. Examples include Capgras delusion, the delusion that a loved one has been replaced by an impostor, and Cotard delusion, the delusion that one is dead or does not exist. Two-factor accounts of such delusions hold that they are the result of both an experiential deficit, for instance flattened affect, coupled with an aberrant cognitive response to that deficit. In this paper we develop a new expressivist two-factor account of (...) delusion. In contrast to existing endorsement and explanationist accounts, which treat delusions as either explanations or endorsements of the contents of these disordered experiences, we hold that delusional beliefs have an expressive function: they characterize, in impressionistic terms, what the subject’s experience is like for them. We show how our account improves upon existing two-factor views in explaining the central features of monothematic delusions, in particular the way in which delusional subjects fall short of the ideal of rationality.

Photographers John Shimon and Julie Lindemann use antique cameras, modern lens technology, artificial light, and contemporary pop culture to create portraits of the people in their native state amidst backyards, living rooms, parking lots, and the landscape of Wisconsin. These recent photographs are juxtaposed with portraits from the Milwaukee Art Museum’s permanent collections, including daguerreotype portraits, ambrotypes, and tintypes of anonymous people taken by nineteenth-century photographers, as well with photographs by such well-known artists as Alfred Stieglitz, Sally Mann, Larry (...) Clark, Walker Evans, Nan Goldin, Eugene von Beuenchenhein, and Francis Ford. The pairings of new and old illustrate the legacy of portraiture and the significance of “posing” before the lens, and each image is enriched by its proximity to another, unmasking sitter, photographer, and viewer. Unmasked & Anonymous: Shimon & Lindemann Consider Portraiture includes more than sixty color and black-and-white photographs plus essays by Shimon, Lindemann, and Milwaukee Art Museum curator Lisa Hostetler.

It is proposed to conceive of representation as an emergent phenomenon that is supervenient on patterns of activity of coarsely tuned and highly redundant feature detectors. The computational underpinnings of the outlined concept of representation are (1) the properties of collections of overlapping graded receptive fields, as in the biological perceptual systems that exhibit hyperacuity-level performance, and (2) the sufficiency of a set of proximal distances between stimulus representations for the recovery of the corresponding distal contrasts between stimuli, as in (...) multidimensional scaling. The present preliminary study appears to indicate that this concept of representation is computationally viable, and is compatible with psychological and neurobiological data. (shrink)

The problem of representing the spatial structure of images, which arises in visual object processing, is commonly described using terminology borrowed from propositional theories of cognition, notably, the concept of compositionality. The classical propositional stance mandates representations composed of symbols, which stand for atomic or composite entities and enter into arbitrarily nested relationships. We argue that the main desiderata of a representational system—productivity and systematicity—can (indeed, for a number of reasons, should) be achieved without recourse to the classical, proposition‐like compositionality. (...) We show how this can be done, by describing a systematic and productive model of the representation of visual structure, which relies on static rather than dynamic binding and uses coarsely coded rather than atomic shape primitives.

The recent essay by Schuklenk and Smalling opposing respect for physicians’ conscientious objections to providing patients with medical services that are legally permitted in liberal democracies is based on several erroneous assumptions. Acting in this manner would have serious harmful effects on the ethos of medicine and of bioethics. A much more nuanced and balanced position is critical in order to respect physicians’ conscience with minimal damage to patients’ rights.

Society's problems cannot be alleviated via mere policy interventions, whether individual- or system-level, when the system is the problem. To bring about true and lasting change to the better, we must replace the present global political-economic system – oligarchic capitalism backed by the power of the state – with one that would let the people take charge of their lives.

Mohandas K. Gandhi (1869–1948)’s relationship with the Jews is explored in this article. The history of this relationship can be divided into two different periods. The first begins during his formative years in South Africa from 1893 to 1914, and the second, during his political activism in India thereafter. The article points out that Gandhi’s close Jewish associates in South Africa, although coming primarily from a Theosophist background, considered their support of Gandhi and his struggle to represent their core Jewish (...) values. Still, Gandhi’s close Jewish supporters did not successfully influence Gandhi regarding Zionism. In retrospect, Gandhi’s objection to Zionism enormously impacted the Indian Congress Party’s position regarding Palestine. The article notes that although Gandhi opposed political Zionism, he supported Zionism as a spiritual movement that could be best realized “within.” Somewhat surprising and little-known fact was a desire on Gandhi’s part to mediate between the Arabs and the Jews in direct talks. Gandhi hoped the Zionist leaders would respond positively to his offer to mediate so that he could advance his teachings of nonviolence while also claiming to represent the Indian Muslims. The article discusses Gandhi’s call to German and European Jews to resist the Nazi regime by adopting Satyagraha, the consequent rift with Jewry that followed, and his silence after the Holocaust. Finally, the article also briefly explores B. R. Ambedkar (1891–1956)’s views on the Jews and the Indian pariahs. (shrink)

To commemorate 40 years since the founding of the Journal of Business Ethics, the editors in chief of the journal have invited the editors to provide commentaries on the future of business ethics. This essay comprises a selection of commentaries aimed at creating dialogue around the theme The Ethics and Politics of Academic Knowledge Production. Questions of who produces knowledge about what, and how that knowledge is produced, are inherent to editing and publishing academic journals. At the Journal of Business (...) Ethics, we understand the ethical responsibility of academic knowledge production as going far beyond conventions around the integrity of the research content and research processes. We are deeply aware that access to resources, knowledge of the rules of the game, and being able to set those rules, are systematically and unequally distributed. One could ask the question “for whom is knowledge now ethical’”? (See the Burrell commentary.) We have a responsibility to address these inequalities and open up our journal to lesser heard voices, ideas, and ways of being. Our six commentators pursue this through various aspects of the ethics and politics of academic knowledge production. Working with MacIntyre’s scheme of practices and institutions, Andrew West provides commentary on the internal good of business ethics learning and education. Inviting us to step out of the cave, Christopher Michaelson urges a clear-eyed, unblinking focus on the purposes and audiences of business ethics scholarship. As developmental editor, Scott Taylor uncovers some of the politics of peer review with the aim of nurturing of unconventional research. Mike Hyman presents his idiosyncratic view of marketing ethics. In the penultimate commentary, Julie Nelson attributes difficulties in the academic positioning of the Business Ethics field to the hegemony of a masculine-centric model of the firm. And finally, Gibson Burrell provides a powerful provocation to go undercover as researcher-investigators in a parallel ethics of the research process. (shrink)

This article analyses the biochemical object of tnf inhibitors from the perspective of living with an autoimmune disease. The author tries to tease out how the concept of immune inhibition is used in tandem with the biochemical object of tnf inhibitors to dominate in defining and narrating what health and disease, normal and pathological, cure and healing can mean in the context of autoimmune bodies. Specifically, and within the ‘pathological’ framework of autoimmune diseases, the pharmacological treatment of tnf inhibition is (...) designed to suppress the ‘overly’ active immune system, thus acting as a negative or suppressing biochemical agent aimed at putting the ‘malfunctioning’ immune system back in balance. As can be seen in the current conjuncture, tnf inhibitors officially —and governmentally— place those taking them in a risk group, as they 'lower' their overall bodily immunity and make them more vulnerable to infectious diseases, while stabilizing their patho-logical, ‘over’-immune uninhibited condition. Part personal narrative of being diagnosed with an autoimmune condition, part speculative autoimmune theory inspired by such a diagnosis, the article ultimately calls for a different form of embodiment that is neither negative nor affirmative, and yet is resistant even to itself.

A metaphor that has dominated linguistics for the entire duration of its existence as a discipline views sentences as edifices consisting of Lego-like building blocks. It is assumed that each sentence is constructed (and, on the receiving end, parsed) ab novo, starting (ending) with atomic constituents, to logical semantic specifications, in a recursive process governed by a few precise algebraic rules. The assumptions underlying the Lego metaphor, as it is expressed in generative grammar theories, are: (1) perfect regularity of what (...) Saussure called langue, (2) infinite potential recursivity of syntactic structures, (3) unlimited human capacity for linguistic creativity, (4) the impossibility of acquiring structural knowledge from examples, and (5) the impossibility of such knowledge being stored in a memory-intensive form (ensembles of exemplars).

An infinite cardinal λ is Magidor if and only if. It is known that if λ is Magidor then for some, and the first such α is denoted by. In this paper we try to understand some of the properties of. We prove that can be the successor of a supercompact cardinal, when λ is a Magidor cardinal. From this result we obtain the consistency of being a successor of a singular cardinal with uncountable cofinality.

A few years ago, a Yemenite patient came to Maimonides Hospital in Brooklyn. The friendly, diminutive gentleman apologized for visiting the clinic in the first place because, as he explained, he was a devotee of Maimonides and invariably used the medical treatments recommended by him rather than current Western medicine. But for this patient’s problem, Maimonides had prescribed garlic. The patient told his doctor that if he ingested garlic, his wife would refuse contact with him. So, having no alternative, he (...) came to our clinic for consultation and to see if there were any other appropriate treatments.Moses Maimonides was one the most important Jewish scholars of all times.

In their 2008 paper, Persson and Savulescu suggest that for moral bioenhancement (MBE) to be effective at eliminating the danger of ‘ultimate harm’ the intervention would need to be compulsory. This is because those most in need of MBE would be least likely to undergo the intervention voluntarily. By drawing on concepts and theories from epidemiology, this paper will suggest that MBE may not need to be universal and compulsory to be effective at significantly improving the collective moral standing of (...) a human populace and reducing the threat of ultimate harm. It will identify similarities between the mechanisms that allow biological contagions (such as a virus) and behaviours (such as those concerned with ethical and unethical actions) to develop, spread, and be reinforced within a population. It will then go onto suggest that, just as with the epidemiological principle of herd immunity, if enough people underwent MBE to reach a minimum threshold then the incidence and spread of immoral behaviours could be significantly reduced, even in those who have not received MBE.

The strangeness of modern physics has sparked several popular books--such as The Tao of Physics--that explore its affinity with Eastern mysticism. But the founders of quantum mechanics were educated in the classical traditions of Western civilization and Western philosophy. In Nature Loves to Hide, physicist Shimon Malin takes readers on a fascinating tour of quantum theory--one that turns to Western philosophical thought to clarify this strange yet inescapable explanation of reality. Malin translates quantum mechanics into plain English, explaining its (...) origins and workings against the backdrop of the famous debate between Niels Bohr and the skeptical Albert Einstein. Then he moves on to build a philosophical framework that can account for the quantum nature of reality. He shows, for instance, how Platonic and Neoplatonic thought resonates with quantum theory. He draws out the linkage between the concepts of Neoplatonism and the more recent process philosophy of Alfred North Whitehead. The universe, Whitehead wrote, is an organic whole, composed not of lifeless objects, but "elementary experiences." Beginning with Whitehead's insight, Malin shows how this concept of "throbs of experience" expresses quantum reality, with its subatomic uncertainties, its constituents that are waves and also particles, its emphasis on acts of measurement. Once any educated person could explain the universe as a vast Newtonian web of cause and effect, but since quantum theory, reality again appears to be richer and more mysterious than we had thought. Writing with broad humanistic insight and deep knowledge of science, and using delightful conversations with fictional astronauts Peter and Julie to explain more difficult concepts, Shimon Malin offers a profound new understanding of the nature of reality--one that shows a deep continuity with aspects of our Western philosophical tradition going back 2500 years, and that feels more deeply satisfying, and truer, than the clockwork universe of Newton.

This is a book about how we see: the environment around us (its surfaces, their layout, and their colors and textures); where we are in the environment; whether or not we are moving and, if we are, where we are going; what things are good for; how to do things (to thread a needle or drive an automobile); or why things look as they do.The basic assumption is that vision depends on the eye which is connected to the brain. The (...) author suggests that natural vision depends on the eyes in the head on a body supported by the ground, the brain being only the central organ of a complete visual system. When no constraints are put on the visual system, people look around, walk up to something interesting and move around it so as to see it from all sides, and go from one vista to another. That is natural vision—and what this book is about. (shrink)

In her paper, Robinson asserts that if one is convinced by the arguments assigning personhood according to a threshold criterion, one should also be open to the potential for a secondary personhood threshold, satisfied when one is pregnant, which confers temporary enhanced moral status. Rather than grounding such a claim on a fetus’s possession, or lack thereof, of personhood, Robinson argues that the pregnant person’s status as a ‘unique being’ is enough to satisfy the requirements of such an additional personhood (...) classification. 1 She justifies her claim via three arguments: (1) that the pregnant person is, in fact, more than a singular individual; (2) that pregnant people play a critical role in the human race’s continuation and (3) that the significant harms and burdens to which pregnant people have been exposed to historically and contemporary requires counterbalancing with enhanced protections. Unfortunately, despite Robinson’s best efforts, she does not... (shrink)

BackgroundArtificial intelligence has been described as the “fourth industrial revolution” with transformative and global implications, including in healthcare, public health, and global health. AI approaches hold promise for improving health systems worldwide, as well as individual and population health outcomes. While AI may have potential for advancing health equity within and between countries, we must consider the ethical implications of its deployment in order to mitigate its potential harms, particularly for the most vulnerable. This scoping review addresses the following question: (...) What ethical issues have been identified in relation to AI in the field of health, including from a global health perspective?MethodsEight electronic databases were searched for peer reviewed and grey literature published before April 2018 using the concepts of health, ethics, and AI, and their related terms. Records were independently screened by two reviewers and were included if they reported on AI in relation to health and ethics and were written in the English language. Data was charted on a piloted data charting form, and a descriptive and thematic analysis was performed.ResultsUpon reviewing 12,722 articles, 103 met the predetermined inclusion criteria. The literature was primarily focused on the ethics of AI in health care, particularly on carer robots, diagnostics, and precision medicine, but was largely silent on ethics of AI in public and population health. The literature highlighted a number of common ethical concerns related to privacy, trust, accountability and responsibility, and bias. Largely missing from the literature was the ethics of AI in global health, particularly in the context of low- and middle-income countries.ConclusionsThe ethical issues surrounding AI in the field of health are both vast and complex. While AI holds the potential to improve health and health systems, our analysis suggests that its introduction should be approached with cautious optimism. The dearth of literature on the ethics of AI within LMICs, as well as in public health, also points to a critical need for further research into the ethical implications of AI within both global and public health, to ensure that its development and implementation is ethical for everyone, everywhere.
