In two studies we investigated the association between physical cleansing and moral and immoral behavior in real-life situations. In Study 1, after a workout at the gym, participants cheated more after taking a shower than before taking one. In the second study, participants donated more money to charity before rather than after they bathed for religious purification. The results extend previous findings about moral cleansing and moral licensing and are discussed within the framework of conceptual metaphor theory.

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.

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)

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.

Das Ziel dieses Textes ist, die Aufmerksamkeit auf einige Voraussetzungen, die als wichtig für besseres Verständnis des Denkens scheinen, das zusätzlich als „kritisches“ bezeichnet wird, zu richten. Zuerst wird einleitend konstatiert, dass die Rede vom „kritischen“ Denken im Kontext der Ausbildung aufgetreten ist, und es wird daran erinnert, dass „Kritisches“ ein wesentlicher Bestandteil des Denkens überhaupt ist. Deshalb werden verschiedene Vernunfttypen vorgestellt, aus denen sich verschiedene Rationalitäts- und Denktypen entwickeln. Dabei wird an zeitgenössische Kritik an der Absolutierung der westlichen dihairetischen (...) Rationalität erinnert, wonach es gezeigt wird, wie sich aus der Einheit der Vernunft die Pluralität von Rationalitäten entwickelt hat. Im folgenden Abschnitt wird die ursprüngliche Vernunft als Einheit von Logos und Mythos dargestellt, fortgesetzt von der Thematisierung dessen, was aus der Perspektive der dihairetischen Rationalität nicht als der Vernunft Zugehöriges anerkannt wird – das Andere der Vernunft. Darauf folgt die Darstellung der Anerkennungsmöglichkeit der Rationalität des Anderen der Vernunft, welche sich in der Metapher und der analogischen Rationalität zeigt. Nächstes Kapitel diskutiert einige Folgemanifestierungen der dihairetischen Rationalität und mit diesen Folgen verbundene Schwierigkeiten in Bezug auf Voraussetzungen der Fähigkeitsentwicklung des kritischen Denkens. Zum Schluss werden einige Bedingungen für kritisches Denken dargestellt. (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.

To illustrate dramatically the progress and potential in the field of synthetic biology, one can begin the story with the 2011 winner of the Lasker Clinical Medical Research Award (Youyou 2011). She was an 81-year-old Chinese scientist, Dr. Tu Youyou, who was given an assignment in 1969 by the Chinese government to find a treatment for malaria from among Chinese herbal medicines. She investigated more than 2,000 Chinese herbal preparations, winnowed them down to some 640 possibilities, obtained 380 extracts from (...) about 200 Chinese herbs, and tested them against a mouse model of malaria. She found one extract, of the Artemisia plant, effective in mice, but she could not reproduce the results consistently. So she .. (shrink)

Autor kritički propituje uvjete i mogućnosti dijaloga između prirodnih znanosti i teologije stvaranja na primjeru dogmatičara Alexandrea Ganoczya. Ganoczy se služi responzorijskom metodom: razvija teologiju stvaranja »od dolje«, konstituirajući zajedničke »platforme« dijaloga gradeći na principu komplementarnosti uz pomoć analogije, te otkrivajući sličnost u načinu izražavanja prirodnih znanosti i teologije . Kao posebna tematska područja teološke refleksije rezultata prirodnih znanosti obrađuju se: samoorganizacija materije i creatio continua; prostorno vremenski kontinuum i vječnost; mozak, duh i Duh Božji; kreativnost i stvaranje te pitanje (...) zla i grijeh.The author analyzes critically the conditions and possibilities of dialogue between natural sciences and theology of creation of the dogmatist Alexandre Ganoczy. Ganoczy uses responsorial method: he develops theology of creation “from below”, constituting common “platforms” of dialogue and building on the principle of complementarity using analogy and discovering similarities in the manner of expression of both natural sciences and theology .The following areas of theological reflection on the results of natural sciences are subject to analysis: selforganization of matter and creatio continua; space-time continuum and eternity; brain, spirit and the Spirit of God; creativity and creation and the question of evil and sin.However, although Ganoczy manages to show that common platforms are much more then modest conclusion that science and theology are not contradictory, in certain topics the dialogue seems to be too associative and the discourse superficial, so that the whole project gains partly essayistic significance.

The theoretical debate in linguistics during the past half-century bears an uncanny parallel to the politics of the (now defunct) Communist Bloc. The parallels are not so much in the revolutionary nature of Chomsky's ideas as in the Bolshevik manner of his takeover of linguistics (Koerner 1994) and in the Trotskyist (“permanent revolution”) flavor of the subsequent development of the doctrine of Transformational Generative Grammar (TGG) (Townsend & Bever 2001, pp. 37–40). By those standards, Jackendoff is quite a party faithful (...)

We study the structural rainbow Ramsey theory at uncountable cardinals. Compared to the usual rainbow Ramsey theory, the variation focuses on finding a rainbow subset that not only is of a certain cardinality but also satisfies certain structural constraints, such as being stationary or closed in its supremum. In the process of dealing with cardinals greater than ω1, we uncover some connections between versions of Chang's Conjectures and instances of rainbow Ramsey partition relations, addressing a question raised in [18].

I was deeply moved and inspired by Jason Dubroff’s article1 objecting to the source of the white coat distributed to the entering medical students at his school. The article stimulated me to ponder its implications and led to some thoughtful discussions with colleagues. Here was a busy medical student who was appropriately disturbed at what he regarded as a kind of ethical failure at the very ceremony, which was meant to exemplify and emphasise the values of humanism. However, unlike many (...) of us who notice evidence of ethical insensitivity, react with a sigh or a comment, and go on with our lives without significant alteration in our normal activities, Jason initiated an investigation of the issue, researched it in his own time, and even proposed remedial actions—a remarkable, unusual and impressive course of events. His article reinforced some of my personal prejudices. To those of my colleagues who nostalgically bewail the alleged decrease in idealism in today’s entering medical students, I can point to Jason as an example of the kind of ethical sensitivity, ….

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.

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)

Beer ’s paper devotes much energy to buttressing the walls of Castle Dynamic and dredging its moat in the face of what some of its dwellers perceive as a besieging army chanting “no cognition without representation”. The divide is real, as attested by the contrast between titles such as “Intelligence without representation” and “In defense of representation”, to pick just one example from each side. It is, however, not too late for people from both sides of the moat to meet (...) on the drawbridge and see if all that energy can be put to a better use. The parley can be organized around an attempt to identify those attributes of representations that both sides may find useful. In my view, one such attribute is the capacity for hierarchical abstraction, an aspect of the representational approach not actually mentioned by Beer. The capacity for abstraction is gained automatically by those theoretical frameworks that opt for the explanatory benefits of representation in understanding cognition. Moreover, without appropriately structured mediating states, a cognitive system would be incapable of dealing with complex reality. Thus, hierarchical abstraction is useful not just for the cognitive scientists in their attempts to scale up their understanding of cognition: it is also indispensable for cognitive systems that aspire to scale up their understanding of the world.

The computational program for theoretical neuroscience initiated by Marr and Poggio (1977) calls for a study of biological information processing on several distinct levels of abstraction. At each of these levels — computational (defining the problems and considering possible solutions), algorithmic (specifying the sequence of operations leading to a solution) and implementational — significant progress has been made in the understanding of cognition. In the past three decades, computational principles have been discovered that are common to a wide range of (...) functions in perception (vision, hearing, olfaction) and action (motor control). More recently, these principles have been applied to the analysis of cognitive tasks that require dealing with structured information, such as visual scene understanding and analogical reasoning. Insofar as language relies on cognition-general principles and mechanisms, it should be possible to capitalize on the recent advances in the computational study of cognition by extending its methods to linguistics.

Although computational considerations suggest that a resource-limited memory system may have to trade off capacity for generalization ability, such a trade-off has not been demonstrated in the past.

Photo by Hannah Busing on Unsplash INTRODUCTION Religion has long provided guidance that has led to standards reflected in some aspects of medical practices and traditions. The recent bioethical literature addresses numerous new problems posed by advancing medical technology and demonstrates an erosion of standards rooted in religion and long widely accepted as almost axiomatic. In the deep soul-searching that pervades the publications on bioethics, several disturbing and dangerous trends neglect some basic lessons of philosophy, logic, and history. The bioethics (...) discourse on medical aid in dying emphasizes similarity over previously recognized important distinguishing features. For example, it overplays a likeness between assistance in dying and the withdrawal of life-saving technology. In many bioethics’ topics, arguments based on a logical continuum are used to question the lines demarcating important moral differences. l. The Line Between Ethical and Not: Logic Based on Continuum Careful case selection, often either end of a continuum, allows the tearing down or ridiculing of many rules and codes across most professions and fields of interest. This situation holds true for traffic laws as well as medical ethics guidelines. It is relatively simple for those who desire to attack a particular viewpoint by selecting a case that makes that position seem untenable. In the ethics realm, good and bad medicine exist at opposite ends of an ethical continuum, with many practices lying in between. For example, much of medical ethics exists between the Nazi criminal physicians and the most sainted nurse or physician. A gradual progression occurred over less than two decades from a utilitarian position that supported limited euthanasia for those with certain mental illnesses to genocide. German society embraced a utilitarian ethic in which the value of human life no longer was intrinsic but instrumental.[1] Many morally significant points on a continuum were then ignored as the misguided utilitarian policy rampantly continued. A point in the continuum to distinguish between ethically justifiable and that which is not can be difficult to identify compared to the two extremes. This continuum is not unique to ethics but can be applied to almost any other aspect of human life and endeavor. Between a severely ill schizophrenic person and a superbly well-adjusted individual, there is a continuum of mental and psychological function. The existence of a continuum should not paralyze thinking and prevent us from drawing lines and identifying moral differences based on objective criteria as well as moral philosophy. Yet, by focusing on a continuum, many bioethicists use logic to disregard dividing lines between an "ethical" and an "unethical" act. Unfortunately, sometimes bioethicists draw revolutionary conclusions that would change the scope of medical practices which is accepted as ethical. There are many examples of similar shifts on the continuum. Many authors argue for the ethical permissibility of abortion by pointing out that the human fetus is no different in various characteristics, one arguing it is as like an ape or chick as it is like a person,[2] and does not achieve unique human and individual characteristics until well into the first year of life.[3] While human fetuses arguably do not have certain distinctive qualities of personhood, most people shy away from the logical next conclusion: permitting infanticide. For example, Joshua Lederberg condemns infanticide, in the face of biological illogic, because of our emotional commitment to infants, to me, a relatively weak explanation. Sir Francis Crick suggests we might consider birth at two days of life in order to decide whether an infant is a "suitable" member of society.[4] Giublini and Minerva suggest that infanticide should be permissible since late pregnancy abortions are permissible, arguing there is no significant difference between a fetus just before birth and an infant just after birth.[5] Clearly the continuum approach would allow for subjective arguments in favor of later infanticide at other points many days post-birth. Years ago, with a cynical tone, I mentioned infanticide as a further step on the continuum beyond abortion, and I was rightly shouted down as being deliberately provocative to assert the logic would ever stretch so far. While it is not an accepted mainstream position, the movement in academic settings from widespread condemnation to limited possible acceptance of infanticide has taken place in an incredibly short time. Public opinion and medical opinion in these areas have shifted dramatically in a short time. In another area, from a biological and chemical point of view, there is a continuum from man down to a single carbon atom. Yet, it would not seem logical to ignore the emotional differences, the meaning of personhood, or the moral distinction between killing an insect and killing a person. ll. A False Continuum: Medical Aid in Dying I assert that there has been an erosion of ethical guidelines in recent years attributable to using continuums to camouflage important distinctions. James Rachels’ work on active and passive euthanasia, which contends that the two are ethically identical, exemplifies that logic.[6] He illustrates this thesis, using a continuum to compare different scenarios with like consequences as morally equivalent, by comparing the deliberate drowning of a child with a deliberate failure to rescue a drowning child when easily able to do so. The author's comparison proposes that since much of the medical profession has already made peace with withholding treatment in order to hasten death, consistency inexorably demands that we permit active euthanasia as well.[7] When permission for active euthanasia was first introduced, it was limited exclusively to patients suffering severely from an intractable, incurable, and irreversible disease. These guidelines have been continuously eroded. There is now a substantial serious consideration for permitting active euthanasia of healthy elderly individuals who feel that they have completed their lives and are "tired of living."[8] There are many moral and factual differences along the ethical continuum. In human life, there is a difference between a live baby and a fetus, between a viable fetus and one that is not, between a fetus and a zygote, and between a zygote and a sperm cell. Similarly, there is a difference between pulling a trigger to kill someone and not interfering in preventing his death, which is reprehensible though both may be. There is a difference between not resuscitating an 80-year-old man with cancer when his heart stops and injecting him with a fatal dose of potassium chloride. I argue that an overt act of taking life repels civilized human beings is to be commended and encouraged as the reverence for human life or even for just a moment of human life is one of the great contributions of our civilization. CONCLUSION As an orthodox Jew, I feel that divinely inspired guidelines that have stood the test of centuries shape my beliefs, and such guidelines contradict medical aid in dying. I cannot speak to the viewpoint of those who do not access religion in defining their moral stance, nor do I implicate them in the current bioethics' trends, as I am not aware of the personal role of religion in the lives of most such authors. While many nonreligious people have a firm philosophical grounding and oppose medical aid in dying, I suggest that in the absence of any religious or other absolute standards, developing logically defensible ethical guidelines may be challenging. At the least, religion may play a role in defining the points on the continuums that are ethically meaningful and refuting the trending beliefs that if the endpoint is the same, allowing different methods of arriving at that end are somehow ethically equal. The continuum of ways death may result does not negate analysis of whether death is brought about in ways that recognize the importance of life. The German philosopher Hans Jonas said, "It is a question whether without restoring the category of the sacred, the category most thoroughly destroyed by the scientific enlightenment, we can have an ethics able to cope with the extreme powers that we possess today and constantly increase and are compelled to use."[9] While countries vary on the role of religion in policy, with many emphasizing freedoms of religion, a recent position paper released by a group of Jewish, Christian, and Moslem leaders suggested the need for agreement on the unique sanctity of human life.[10] I would recommend that such a document serve as an example of consensus on critical foundational bioethical guidelines for democratic secular societies. - [1] Alexander L Medical science under dictatorship.

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.

What insights does comparative biology provide for furthering scienti¿ c understanding of the evolution of dynamic coordination? Our discussions covered three major themes: (a) the fundamental unity in functional aspects of neurons, neural circuits, and neural computations across the animal kingdom; (b) brain organization –behavior relationships across animal taxa; and (c) the need for broadly comparative studies of the relationship of neural structures, neural functions, and behavioral coordination. Below we present an overview of neural machinery and computations that are shared (...) by all nervous systems across the animal kingdom, and the related fact that there really are no “simple” relationships in coordination between nervous systems and the behavior they produce. The simplest relationships seen in living organisms are already fairly complex by computational standards. These realizations led us to think about ways that brain similarities and differences could be used to produce new insights into complex brain–behavior phenomena (including a critical appraisal of the roles of cortical and noncortical structures in mammalian behavior), and to think brieÀy about how future studies could best exploit comparative methods to elucidate better general principles underlying the neural mechanisms associated with behavioral coordination. In our view, it is unlikely that the intricacies interrelating neural and behavioral coordination are due to one particular manifestation (such as neural oscillation or the possession of a six-layered cortex). Instead of considering the human cortex to be the standard against which all things are measured (and thus something to crow about), both broad and focused comparative studies on behavioral similarities and differences will be necessary to elucidate the fundamental principles underlying dynamic coordination.

Construction-based approaches to syntax (Croft, 2001; Goldberg, 2003) posit a lexicon populated by units of various sizes, as envisaged by (Langacker, 1987). Constructions may be specified completely, as in the case of simple morphemes or idioms such as take it to the bank, or partially, as in the expression what’s X doing Y?, where X and Y are slots that admit fillers of particular types (Kay and Fillmore, 1999). Constructions offer an intriguing alternative to traditional rule-based syntax by hinting at (...) the extent to which the complexity of language can stem from a rich repertoire of stored, more or less entrenched (Harris, 1998) representations that address both syntactic and semantic issues, and encompass, in addition to general rules, “totally idiosyncratic forms and patterns of all intermediate degrees of generality” (Langacker, 1987, p.46). Because constructions are by their very nature language-specific, the question of acquisition in Construction Grammar is especially poignant. We address this issue by offering an unsupervised algorithm that learns constructions from raw corpora. (shrink)

We outline an unsupervised language acquisition algorithm and offer some psycholinguistic support for a model based on it. Our approach resembles the Construction Grammar in its general philosophy, and the Tree Adjoining Grammar in its computational characteristics. The model is trained on a corpus of transcribed child-directed speech (CHILDES). The model’s ability to process novel inputs makes it capable of taking various standard tests of English that rely on forced-choice judgment and on magnitude estimation of linguistic acceptability. We report encouraging (...) results from several such tests, and discuss the limitations revealed by other tests in our present method of dealing with novel stimuli. (shrink)

We describe a method for automatic word sense disambiguation using a text corpus and a machine- readable dictionary (MRD). The method is based on word similarity and context similarity measures. Words are considered similar if they appear in similar contexts; contexts are similar if they contain similar words. The circularity of this definition is resolved by an iterative, converging process, in which the system learns from the corpus a set of typical usages for each of the senses of the polysemous (...) word listed in the MRD. A new instance of a polysemous word is assigned the sense associated with the typical usage most similar to its context. Experiments show that this method performs well, and can learn even from very sparse training data. (shrink)

The learnability of features and their dependence on task and context do not rule out the possibility that primitives used for constructing new features are as small as pixels, nor that they are as large as object parts, or even entire objects. In fact, the simplest approach to feature acquisition may be to treat objects not as if they are composed of unknown primitives according to unknown rules, but rather as if they are what they seem: patterns of atomic features, (...) standing in various similarity relationships to other objects, which serve as holistic features.

Computer vision systems are, on most counts, poor performers, when compared to their biological counterparts. The reason for this may be that computer vision is handicapped by an unreasonable assumption regarding what it means to see, which became prevalent as the notions of intrinsic images and of representation by reconstruction took over the field in the late 1970’s. Learning from biological vision may help us to overcome this handicap.
