There are many social psychological theories regarding the nature of prejudice, but only one major theory of prejudice reduction: under the right circumstances, prejudice between groups will be reduced with increased contact. On the one hand, the contact hypothesis has a range of empirical support and has been a major force in social change. On the other hand, there are practical and ethical obstacles to any large-scale controlled test of the hypothesis in which relevant variables can (...) be manipulated. Here we construct a spatialized model that tests the core hypothesis in a large array of game-theoretic agents. Robust results offer a new kind of support for the contact hypothesis: results in simulation do accord with a hypothesis of reduced prejudice with increased contact. The spatialized game-theoretic model also suggests a deeper explanation for at least some of the social psychological phenomena at issue. (shrink)

We apply spatialized game theory and multi-agent computational modeling as philosophical tools: (1) for assessing the primary social psychological hypothesis regarding prejudice reduction, and (2) for pursuing a deeper understanding of the basic mechanisms of prejudice reduction.

People recognize faces of their own race more accurately than faces of other races. The “contact” hypothesis suggests that this “other‐race effect” occurs as a result of the greater experience we have with own‐ versus other‐race faces. The computational mechanisms that may underlie different versions of the contact hypothesis were explored in this study. We replicated the other‐race effect with human participants and evaluated four classes of computational face recognition algorithms for the presence of an other‐race (...) effect. Consistent with the predictions of a developmental contact hypothesis, “experience‐based models” demonstrated an other‐race effect only when the representational system was developed through experience that warped the perceptual space in a way that was sensitive to the overall structure of the model's experience with faces of different races. When the model's representation relied on a feature set optimized to encode the information in the learned faces, experience‐based algorithms recognized minority‐race faces more accurately than majority‐race faces. The results suggest a developmental learning process that warps the perceptual space to enhance the encoding of distinctions relevant for own‐race faces. This feature space limits the quality of face representations for other‐race faces. (shrink)

"The Contact Between Minds: A Metaphysical Hypothesis" by Cecil Delisle Burns is a thought-provoking book that explores the fascinating concept of mind-to-mind communication. Burns, a respected philosopher, delves into the realms of metaphysics to propose a hypothesis that challenges conventional notions of communication and the boundaries of human consciousness. With meticulous reasoning and deep philosophical inquiry, Burns presents his ideas on how minds may connect and exchange information beyond the limitations of traditional communication channels. This book invites (...) readers to contemplate the mysteries of the human mind and opens up new possibilities for understanding the interconnectedness of consciousness. (shrink)

(This version was submitted to Behavioral and Brain Science. A revised version was published by Biological Theory) Estimates of autism’s incidence increased 5-10 fold in ten years, an increase which cannot be genetic. Though many mutations are associated with autism, no mutation seems directly to cause autism. We need to find the direct cause. Complexity science provides a new paradigm - confirmed in biology by extensive hard data. Both the body and the personality are complex dynamic systems which spontaneously self-organize (...) from simple dynamic systems. Autism may therefore be caused by the failure of a simple dynamic system. We know that infants who cannot track their mother’s face often become autistic, that eye-contact initiates intersubjectivity which is blocked in autism, and that the infant-mother pair seems designed to promote eye-contact, as does the eye’s appearance. This author earlier proposed that failure of eye-contact might directly cause autism and that early non-maternal childcare, including television/video, would therefore be statistically linked to autism. Waldman et al. (2008; 2006) recently proved that autism is strongly linked to precipitation (indoor activity) and to the introduction of cable. The most plausible explanation? Early exposure to television/video is linked to autism. Furthermore a normal developmental cascade (blocked in autism) has been deciphered: (a) Infant-mother eye-contact triggers increased maternal attention. (b) Early maternal attention permanently increases not only baseline vasopressin but also that oxytocin release which is triggered by subsequent maternal attention. (c) Vasopressin and oxytocin promote face recognition, gazing-at-the-eyes, emotion recognition, and social bonding. The eye-contact hypothesis suggests a clinical study addressing prevention: recruit prospective parents who agree to curtail television/video/computer/wi-fi in their families; measure autism’s incidence in their children.

The contact hypothesis has dominated work on prejudice reduction and is often described as one of the most successful theories within social psychology. The hypothesis has nevertheless been criticized for not being applicable in real life situations due to unobtainable conditions for direct contact. Several indirect contact suggestions have been developed to solve this “application challenge.” Here, we suggest a hybrid strategy of both direct and indirect contact. Based on the second-person method developed in (...) social psychology and cognition, we suggest working with an engagement strategy as a hybrid hypothesis. We expand on this suggestion through an engagement-based intervention, where we implement the strategy in a theater performance and investigate the effects on prejudicial attitudes toward people with physical disabilities. Based on the results we reformulate our initial engagement strategy into the Enact hypothesis. To deal with the application challenge, this hybrid hypothesis posits two necessary conditions for prejudice reduction. Interventions should: work with engagement to reduce prejudice, and focus on the second-order level of attitudes formation. Here the aim of the prejudice reduction is not attitude correction, but instead the nuancing of attitudes. (shrink)

Mounting evidence shows that nature contact is associated with affective benefits. However, the psychological mechanisms responsible for these effects are not well understood. In this study, we examined whether more time spent in nature was associated with higher levels of positive affect in general, and lower levels of negative affect and rumination in general. We also conducted a cross-sectional mediation analysis to examine whether rumination mediated the association of nature contact with affect. Participants reported their average time spent (...) in nature each week, as well as their general levels of positive and negative affect, and the degree to which they typically engaged in rumination in daily life. We then used structural equation modeling to test our hypotheses. Our results support the hypothesis that nature contact is associated with general levels of affect, and that rumination mediates this association for negative affect, and marginally mediates this association for positive affect.

Realism about the external, natural world is an overarching empirical hypothesis. The method of hypothetical realism rejects as an excessive concession to the skeptic these two assumptions of constructivist intuitionism: first, that everything real must be exhaustively inspectable; and second, that our beliefs are to be justified to the point of certainty. We prefer to say that nothing is ever known directly; that all of our contact with the world is mediated by thoughts, words, and percepts construed as (...) signs having referents distinct from themselves. We organize these signs into meaningful and possibly true hypotheses as we speculate--in practice, science and metaphysics--about a world we have not made. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:A Hypothesis Concerning the Character of Islamic ArtAsli GocerWhy Islamic art has the distinctive features it has continues to generate clashing explanations. The Islamic visual treasury has no figural images, for instance, and three-dimensional sculpture or large scale oil painting, but instead contains miniatures, vegetal ornaments, arabesque surface patterns, and complex geometrical designs. To account for the phenomena the following radically opposing theories have been offered: the influence (...) of Judaism, the Quranic prohibition against making images, 1 Islamic resentment of the glory of Byzantine icons, 2 logocentricism of classical Islam, 3 the spiritual dimension of Islam, 4 tacit Islamic assertion of “otherness,” 5 and contingency of history. 6 The merits of these theories have been roundly discussed in the literature, and so I will not repeat the task here. I will insist that none of these theories offer a coherent explanation for all arts, but my presumption is that such an explanation is possible. In nonvisual arts the Muslim prefers simple tunes over that of the symphony, for instance, whirling dervishes over the ballet, and lyric poetry over dramatic literature. In my view what explains the common characteristic of all these arts is a certain kind of Islamic attitude informed by a certain philosophical outlook. Although it would be hasty to suggest the existence of a monolithic [End Page 683] Islamic art, it would be equally rash to deny some striking commonalities among its diverse examples. 7The following observation by a Muslim scholar is notable in this regard: “Whether in the great courtyard of the Delhi Mosque or the Qarawiyyin in Fez, one feels oneself within the same artistic and spiritual universe despite all the local variations in material, structural techniques, and the like.” 8 Some cite geometry as what mediates that feeling to the observer despite the cultural divergences in style. 9 Even those who have given up the search for the universal or the spiritual in Islamic art cannot help but see in it the classical ideal of beauty. 10 It is this classical heritage that in fact holds one of the important keys to the puzzle at hand. In particular I shall claim that Islamic art is the living image of what Plato has in mind for art in a theocratic state. Clearly, to refer to Plato and art in the same breath invites trouble. As is well enough known, giving a general interpretation of Plato’s views on the nature of art is a very complex endeavor. 11 Even in the face of grave difficulties in textual exegesis, however, there is sufficient evidence that Plato has some settled views on art. Those pertinent to our discussion here involve two claims, that beauty and goodness are divine and that all human endeavor (including artistic creation) must imitate the divine. 12 Although Platonic strain in Islam has been noted in other areas, its persistent legacy has been overlooked in art. 13 I shall argue that the Platonic influence on Islamic thought can be traced not only to political philosophy 14 and geometry, 15 as it has been commonly accepted, but also aesthetics. 16 A philosophical explanation of the Islamic attitude toward art may therefore be derivable from the Platonic axiom that god is the paradigm of beauty, which is the cosmological principle of [End Page 684] order and harmony; and as all created things, art, too, must reflect the divine paradigm.Before defending this ahistorical hypothesis on the character of Islamic art so reviled in recent literature, a few caveats are in order. “Islamic art” contains redundant terms. Strictly speaking all art in Islam is “Islamic,” because for the Muslim art is a crucial point of contact with the divine. That art should direct the mind to the divine is also Plato’s view. 17 Second, the categories that have traditionally been used to describe Islamic art such as “aniconic” and “nonrepresentational” are unhelpful for the problem at hand. 18 When it comes to the issue of iconography in Islamic arts, there is no consensus, for Islamicists are notably divided on the semiotic dimension of the Islamic visual language. The question of whether the geometric surface pattern is essentially iconography, for instance, is yet... (shrink)

Image-making is a nearly universal human behavior, yet the visual strategies and conventions to represent things in pictures vary greatly over time and space. In particular, pictorial styles can differ in their degree of figurativeness, varying from intersubjectively recognizable representations of things to very stylized and abstract forms. Are there any patterns to this variability, and what might its ecological causes be? Experimental studies have shown that demography and the structure of interaction of cultural groups can play a key role: (...) the greater the degree of contact with other groups, the more recognizable and less abstract are the representations. Here we test this hypothesis on a real-world dataset for the first time. We constructed a balanced database of Indigenous Australian rock art motifs from both isolated and contact Aboriginal groups (those often in contact with other groups). We then ran a survey asking participants to judge the recognizability of the motifs and to provide interpretations. Results show that motifs from contact Aboriginal groups were more likely to be judged as inter-subjectively recognizable and also elicited more convergent descriptions than motifs from isolated groups. This is consistent with the idea that intergroup contact is likely to be an important factor in the cultural evolution of pictorial representation. We discuss the implications of these findings for the archaeology and anthropology of art, and the parallels with language evolution. (shrink)

Despite decades of research on the reconstruction of proto-Korean-Japanese (pKJ), some scholars still reject a genetic relationship. This study addresses their doubts in a new way, interpreting comparative linguistic data within a context of material and cultural evidence, much of which has come to light only in recent years. The weaknesses of the reconstruction, according to J. Marshall Unger, are due to the early date at which pKJ split apart and to lexical material that the pre-Korean and pre-Japanese branches later (...) borrowed from different languages to their north and south, respectively. Unger shows that certain Old Japanese words must have been borrowed from Korean from the fourth century C.E., only a few centuries after the completion of the Yayoi migrations, which brought wet-field rice cultivation to Kyushu from southern Korea. That leaves too short an interval for the growth of two distinct languages by the time they resumed active contact. Hence, concludes Unger, the original separation occurred on the peninsula much earlier, prior to reliance on paddy rice and the rise of metallurgy. Non-Korean elements in ancient peninsular place names were vestiges of pre-Yayoi Japanese language, according to Unger, who questions the assumption that Korean developed exclusively from the language of Silla. He argues instead that the rulers of Koguryo, Paekche, and Silla all spoke varieties of Old Korean, which became the common language of the peninsula as their kingdoms overwhelmed its older culture and vied for dominance. Was the separation so early as to vitiate the hypothesis of a common source language? Unger responds that, while assuming non-relationship obviates difficulties of pKJ reconstruction, it fares worse than the genetic hypothesis in relation to non-linguistic findings, and fails to explain a significant number of grammatical as well as lexical similarities. Though improving the reconstruction of pKJ will be challenging, he argues, the theory of genetic relationship is still the better working hypothesis. The Role of Contact in the Origins of the Japanese and Korean Languages shows how an interdisciplinary approach can shed light on a difficult case in which the separation of two languages lies close to the time horizon of the comparative method.

This article attempts to show why an experimental hypothesis is plausible and merits testing; in brief, the hypothesis is that autism begins with a failure in early learning and that changing the environment of early learning would dramatically change its incidence. Strong statistical evidence supporting this hypothesis has been published by Waldman et al.

This article also suggests that the (...) current epidemic of autism is serious enough, and intellectually mysterious enough, to merit attention from a wider community of brain scientists: New ideas are needed.

Many works of science fiction, for example those of David Brin, Larry Niven, and Poul Anderson, assume that our galaxy is populated by many intelligent alien species that we will eventually contact for cooperation, competition, or perhaps combat. Isaac Asimov, on the other hand, assumed in his Foundation Series that humanity would spread out into the empty galaxy and colonize it without encountering other intelligent species.

Becoming a crime victim is often associated with the development of psychological distress symptoms. In turn, these symptoms have been found to be related to a decrease in perceived social support by the victim. From a uses and gratifications point of view, the increase in distress and the decrease in perceived social support could well affect a victim’s television use. Furthermore, the compensation hypothesis proposes that people with little social contact use mass media to compensate for social isolation. (...) It could therefore be hypothesized that increased use of television for reasons of companionship is related to higher levels of psychological distress and lower levels of perceived social support. The present study used a structural equation model to test this hypothesis. The sample consisted of 212 Flemish victims of crime. The results confirm the proposed relationships and hypotheses. Directions for future research are discussed. (shrink)

This article argues that Karl Jaspers’s account of the rise of the Axial Age phenomenon is deficient owing to his failure to consider the natural law as a plausible cause for its development. The Axial Age concept—which precedes Jaspers, who nevertheless popularized it—claims that widely separated civilizations from the Ancient Greeks and Hebrews to the Persian, Hindu, Buddhist, and Confucian cultures all began to display sophisticated political and moral development from 800–200 BC, without any known contact. Jaspers regarded its (...) rise as a mystery. However, given ancient legal codes containing moral precepts long predating this period, the natural law hypothesis serves as the most plausible explanation of this ‘mystery’ of mankind’s dawning moral awareness.

The challenge of intercultural relations has become an important issue in many societies. In spite of the claimed value of intercultural diversity, successful outcomes as predicted by the contact hypothesis are but one possibility; on occasions intercultural contact leads to intolerance and hostility. Research has documented that one key mediator of contact is perspective taking. Differences in perspective are significant in shaping perceptions of contact and reactions to it. The ability to take the perspective of (...) the other and to understand it in its own terms is a necessary condition for successful intergroup outcomes. This paper sheds light on the processes involved in intercultural perspective taking by elaborating the notion of the point of view based on social representations theory. The point of view provides a theory of social positioning that can analyse cultural encounters between social actors, and identify the conditions for positive relations. Insights are drawn from a study of public views on the relative merits of science and religion, following a documentary by Richard Dawkins in which it was suggested that religion is a source of evil. The findings demonstrate that the point of view may be categorised according to a three-way taxonomy according to the extent to which it is open to another perspective. A point of view may be monological—closed to another's perspective entirely, dialogical—open to the possibility of another perspective while maintaining some percepts as unchallengeable, or metalogical—open to another's perspective based on the other's frame of reference.

The powerful role that teachers can play in our development is the focus Binyamin, Jayusi, and Tamir’s chapter in this volume. They argue that teachers, in particular teachers that don’t share the same background as their students, can help counter the increasing polarization that characterizes our current era. In these critical notes I raise three challenges to their proposal. First, by exploring the mechanisms of polarization I demonstrate that polarization is not a problem unique to thick diversity or thick multiculturalism. (...) Second, the central premise of the authors’ proposal rests on the ability of greater contact to reduce prejudice. The contact hypothesis, however, has numerous backlash effects and unintended consequences that can increase prejudice rather than reduce prejudice. These backlash effects and unintended consequences raise serious doubts for the success of placing minority teachers in majority classrooms to reduce prejudice. Third, I raise concerns about how the proposal tokenizes minority teachers, the use of instrumental rationales for diversity, and the politics of deference and being-in-the-room privilege that also go unaddressed in their proposal.

In this paper I remark on Tanesini’s (2021) account of intellectual humility and servility as attitudes, with a focus on how this proposal intersects with the psychology literature on intellectual humility. I begin by discussing the implications this may have for empirical measures of intellectual humility, including concerns that some current measures seem to do a better job of capturing dispositional limitations-owning than virtuous intellectual humility. Additionally, I raise concerns that excluding interpersonal features and a motivation to learn from conceptualizations (...) of intellectual humility risk vicious manifestations of intellectual humility. Finally, I build on Tanesini’s (2021) ameliorative proposal centered on affirming one’s values by offering some specific strategies drawn from several psychology theories. These include Acceptance and Commitment Therapy, Social Learning Theory, and the Social Contact Hypothesis. (shrink)

Women's experiences with sexual harassment were analyzed with three types of variables: occupational and workplace sex ratios, organizational policies and procedures for dealing with sexual harassment problems, and women's cultural status. Regression analyses revealed that extent of contact with men was a key predictor of incidence of harassment, number of different types of harrassment, sexual comments, sexual categorical remarks, and sexual materials. Gender predominance was a significant predictor of physical threats and sexual materials. Informational methods were less successful than (...) proactive methods in reducing incidents of sexual harassment. The analyses support two generalizations. The “contact hypothesis” tested and verified by Gutek and her colleagues provides a substantive understanding of our findings on workplace and occupational numerical predominance. Second, organizations that take a variety of steps to address sexual harassment are more apt to be successful in curtailing the problem than those relying mainly on “get out the word” techniques.

Talk of ‘robustness’ remains vague, despite the fact that it is clearly an important parameter in evaluating models in general and game-theoretic results in particular. Here we want to make it a bit less vague by offering a graphic measure for a particular kind of robustness— ‘matrix robustness’— using a three dimensional display of the universe of 2 x 2 game theory. In a display of this form, familiar games such as the Prisoner’s Dilemma, Stag Hunt, Chicken and Deadlock appear (...) as volumes, making comparison easy regarding the extent of different game-theoretic effects. We illustrate such a comparison in robustness between the triumph of Tit for Tat in a spatialized environment (Grim 1995, Grim, Mar, and St. Denis 1998) and a spatialized modeling of the Contact Hypothesis regarding prejudice reduction (Grim, et. al 2005a, 2005b). The geometrical representation of relative robustness also offers a possibility for links between geometrical theorems and results regarding robustness in game theory. (shrink)

Robustness has long been recognized as an important parameter for evaluating game-theoretic results, but talk of ‘robustness’ generally remains vague. What we offer here is a graphic measure for a particular kind of robustness (‘matrix robustness’), using a three-dimensional display of the universe of 2 × 2 game theory. In such a measure specific games appear as specific volumes (Prisoner’s Dilemma, Stag Hunt, etc.), allowing a graphic image of the extent of particular game-theoretic effects in terms of those games.

In an earlier study by Nair,1 undergraduate national servicemen were interviewed regarding their perceptions on their conscript experience and nation-building. The present study examines the congruent perceptions of military commanders in the context of social psychological theory and research. Twenty senior military commanders were selected to represent a cross-section of formations and appointments in the army. They were individually interviewed with particular reference to their recall of policies, procedures and practices in conscript service that might have a bearing on nation- (...) building. Verbatim transcriptions of each interview were scrutinized and responses coded and tallied. There was clear identification of the unifying effect of common barracks and training regimes across economic, ethnic and religious differences. The findings provide converging evidence for the presence of the psychological effects of superordinate goals,2 the minimal group paradigm, 3 and the contact hypothesis,4 serving to build a cohesive nation. There were also recurrent and converging attributions of the military experience resulting in national servicemen with the qualities of discipline, responsibility, team spiritedness and physical fitness. It was perceived that these acquired positive qualities were carried over to civilian life and characterized the Singapore workforce. (shrink)

People's opinions toward polygamy were examined in a study of 1369 adults who were current or former members of the Church of Jesus Christ of Latter-day Saints. Questions addressed several areas: polygamy and the law, respondents' perceptions of polygamous women, the potential link between legalizing gay marriage and legalizing polygamy, polygamists' reliance on social welfare programs, and the ability of teens raised in polygamy to leave that lifestyle. Consistent with the contact hypothesis, multiple regression analyses showed that people (...) who knew a polygamist held more favorable opinions of polygamy. Polygamists, men, infrequent church attenders, and older people also tended to hold more favorable opinions of polygamy. Educational attainment showed weak associations with opinions, while marital status failed to predict opinions toward polygamy. (shrink)

Drawing on findings from the study of prejudice and prejudice reduction, we identify a number of mechanisms through which religious communities may influence the intergroup attitudes of their members. We hypothesize that religious participation could in principle either reduce or promote prejudice with respect to any given target group. A religious community’s influence on intergroup attitudes will depend upon the specific beliefs, attitudes, and practices found within the community, as well as on interactions between the religious community and the larger (...) social environment in which it is embedded. Basing our proposals on findings from the literature on prejudice formation and prejudice reduction allows us to outline useful directions for future studies of religion and prejudice. (shrink)

This article is a rebuttal to Robert G. Cavin and Carlos A. Colombetti’s article, “Assessing the Resurrection Hypothesis: Problems with Craig’s Inference to the Best Explanation,” which argues that the Standard Model of current particle physics entails that non-physical things (like a supernatural God or a supernaturally resurrected body) can have no causal contact with the physical universe. As such, they argue that William Lane Craig’s resurrection hypothesis is not only incompatible with the notion of Jesus physically (...) appearing to the disciples, but the resurrection hypothesis is significantly limited in both its explanatory scope and explanatory power. This article seeks to demonstrate why their use of the Standard Model does not logically entail a rejection of the physical resurrection of Jesus when considering the scope and limitations of science itself.

Different anesthetics are known to modulate different types of membrane-bound receptors. Their common mechanism of action is expected to alter the mechanism for consciousness. Consciousness is hypothesized as the integral of all the units of internal sensations induced by reactivation of inter-postsynaptic membrane functional LINKs during mechanisms that lead to oscillating potentials. The thermodynamics of the spontaneous lateral curvature of lipid membranes induced by lipophilic anesthetics can lead to the formation of non-specific inter-postsynaptic membrane functional LINKs by different mechanisms. These (...) include direct membrane contact by excluding the inter-membrane hydrophilic region and readily reversible partial membrane hemifusion. The constant reorganization of the lipid membranes at the lateral edges of the postsynaptic terminals (dendritic spines) resulting from AMPA receptor-subunit vesicle exocytosis and endocytosis can favor the effect of anesthetic molecules on lipid membranes at this location. Induction of a large number of non-specific LINKs can alter the conformation of the integral of the units of internal sensations that maintain consciousness. Anesthetic requirement is reduced in the presence of dopamine that causes enlargement of dendritic spines. Externally applied pressure can transduce from the middle ear through the perilymph, cerebrospinal fluid, and the recently discovered glymphatic pathway to the extracellular matrix space, and finally to the paravenular space. The pressure gradient reduce solubility and displace anesthetic molecules from the membranes into the paravenular space, explaining the pressure reversal of anesthesia. Changes in membrane composition and the conversion of membrane hemifusion to fusion due to defects in the checkpoint mechanisms can lead to cytoplasmic content mixing between neurons and cause neurodegenerative changes. The common mechanism of anesthetics presented here can operate along with the known specific actions of different anesthetics. (shrink)

Merleau-Ponty's «Phenomenology of Perception» suggests perception to be the primary level of the giveness of the world. Perception appears as always an incomplete synthesis of the plural, bringing together bodily and material aspects. Such the simplest interpretation of perception as rendering a contact within the dyad «body-world» is a preliminary axiom for explaining the rest of the process of noematic sense formation. At the same time, Merleau-Ponty’s theoretical intuitions clearly presuppose more, and perception is also thought of as the (...) final point where sense is already given by some way. Thus, in Phenomenology, the second interpretation of perception presumes it to be sense-giving accompanied by the tacit cogito. Merleau-Ponty suggests that these interpretations are compatible with each other, but the transition between them seems really problematic. In the research author shos that the limit of the initial synthesis of perception - some sense of the perceived (exemplyfing meanings as «this horse», «the green density that rushed towards me») - is unattainable from within perception itself and by its means. Perception is itself mediated by other faculties, such as memory, reflection, and imagination. Argumentation for this thesis is carried out in several ways; the relations in the perception/imagination pair show us the most characteristic case, where Merleau-Ponty, judging by later works, himself comes close to recognizing the limitations of the hypothesis of «the world of perception», to the need for a phenomenological development of the topic of faculties. Based on the application of the phenomenological method and the analysis of the conceptual constructions of Merleau-Ponty, we can conclude the following: «the world of perception» does not exist, but the phenomenology of faculties is demanded.

One of the major problems (or sometimes pseudo-problems) that archaeologists and historians encounter in the study of ancient cultures is the need to differentiate and to identify the sources of the various concepts, techniques, institutions, forms, designs, motifs, etc., that, at any given moment of time, form the constituent elements of the culture or cultural product to which they have turned their attention; or—to pose the question in its proper framework—to analyse the process of cultural formation inherent in the subject (...) of their study. Such considerations have a special significance for archaeologists, whose essential concern is with the often incomplete assemblages of material remains left behind by the cultures and civilizations of the past, and whose central task is to enumerate and reconstitute the structures and processes that were operative in the societies in question. The study of acculturation—culture change, cultural diffusion, “stimulus diffusion,” culture contact, etc.—has been part of the theoretical and empirical concerns of anthropologists and sociologists since some decades ago, and the subject of an old and now almost abandoned debate. While the terminology of the social sciences concerned with living societies can also be found in archaeological and historical discussion, such concerns have had inadequate application in the fields of archaeological and historical practice. What has dominated and, to a great extent, continues to dominate historical studies is what we might call “the ‘theory’ of influence” and its corollary, “the migration hypothesis.” Thus, it would not be an exaggeration to say that one of the leading aspects of the study of a past society or culture is the concern with the “parent” culture(s) which influenced it, or the search for the location of its “migratory origins.” While this is especially true of studies relating to the societies of the Third World, it is not exclusively so—as we see, for instance, in the case of European prehistory. The immediate epistemological sources of such approaches are not difficult to identify, being principally located in 19th century diffusionism and, as we shall see shortly, in colonial ideology.

Hierarchical Bayesian models (HBMs) provide an account of Bayesian inference in a hierarchically structured hypothesis space. Scientific theories are plausibly regarded as organized into hierarchies in many cases, with higher levels sometimes called ‘paradigms’ and lower levels encoding more specific or concrete hypotheses. Therefore, HBMs provide a useful model for scientific theory change, showing how higher‐level theory change may be driven by the impact of evidence on lower levels. HBMs capture features described in the Kuhnian tradition, particularly the idea (...) that higher‐level theories guide learning at lower levels. In addition, they help resolve certain issues for Bayesians, such as scientific preference for simplicity and the problem of new theories. *Received July 2009; revised October 2009. †To contact the authors, please write to: Leah Henderson, Massachusetts Institute of Technology, 77 Massachusetts Avenue, 32D‐808, Cambridge, MA 02139; e‐mail: [email protected].

PYRRHONIAN BUDDHISM: AN IMAGINATIVE RECONSTRUCTION -/- Author: -/- Adrian Kuzminski 279 Donlon Road Fly Creek, NY 13337 USA -/- Description of Pyrrhonian Buddhism: -/- The ancient Greek sceptic philosopher, Pyrrho of Elis, accompanied Alexander the Great to India, where he had contacts with Indian sages, so-called naked philosophers (gymnosophists), among whom were very probably Buddhist mendicants, or sramanas. My work, entitled Pyrrhonian Buddhism, takes seriously the hypothesis that Pyrrho’s contact with early Buddhists was the occasion of his rethinking, (...) in a Greek philosophical idiom, of what he experienced in those encounters. This has major implications for our understanding of both Buddhism and Pyrrhonism. -/- Pyrrho’s rethinking of Buddhism, I argue, enabled him to introduce into Greek philosophy and culture several key Buddhist notions. These include the primacy and interdependence of immediate phenomenal experience (which the Buddhists called dependent origination), the suspension of judgment about beliefs lacking phenomenal verification (reflecting the scepticism of the Buddha about ‘unanswered’ or ‘metaphysical’ questions), and the promise of personal enlightenment said to follow such suspension, which Pyrrho called ataraxia, and the Buddhists called bodhi. -/- Pyrrho, like Socrates, wrote nothing, but the movement he founded—Pyrrhonism--became an important tradition in Western philosophy. When the texts of later Pyrrhonian philosophers, particularly Sextus Empiricus, were redicovered during the Renaissance, they sparked a reexamination of the foundations of knowledge, thereby helping to prompt the modern scientific revolution. -/- The notion that early Buddhism played a pivotal role in the birth of ancient Greek Pyrrhonian philosophy remains provocative, but has found increasing support in recent years. An earlier work of mine, Pyrrhonism: How the Ancient Greeks Reinvented Buddhism (Lexington Books, 2008), was, as far as I know, the first book-length comparison of the common features of the two traditions. My current work, Pyrrhonian Buddhism, seeks to broaden and deepen this comparison. It argues that ancient Greek Pyrrhonism is best understood as a fully developed but hitherto largely unrecognized Western version of Buddhism. -/- The Introduction reviews our current understanding of Pyrrhonism in light of recent scholarship on ancient Greek-Indian cultural exchanges, and outlines the methodology I employ. -/- Part I of the book offers re-readings of the classic Pyrrhonian texts, with parallels to Buddhism in mind, including Diogenes Laertius (Chapter One), Sextus Empiricus (Chapter Two) and Timon and Aulus Gellius (Chapter Three). -/- Part II enlists the rubric of the Three Turnings of the Wheel of Dharma to illuminate the fundamental points of comparison between early Buddhism and ancient Pyrrhonism. -/- The First Turning (Chapter Four) centers on the Buddhist insistence on the dependent origination of the objects of immediate consciousness, which can also be found in the understanding of immediate experience expressed in the phenomenalistic atomism of the Pyrrhonists. The Second Turning (Chapter Five), as posed by the ‘unanswered questions’ of the Buddha and the ‘emptiness’ of the Madhyamaka, finds its Pyrrhonian correlation in the suspension of judgment over ‘indeterminate’ beliefs. And the Third Turning (Chapter Six), reported as bodhi in Buddhism and ataraxia in Pyrrhonism, is shown in both traditions to follow liberation from suffering and existential angst, caused by what the Buddhists call our attachments and the Pyrrhonists call our beliefs. -/- Other Writers/Commentators: -/- Aspects of the Pyrrhonian/Buddhism question have been addressed by Edward Conze, Everard Flintoff, Thomas McEvilley, Jay Garfield, Mathew Neale, Ethan Mills, Christopher Beckwith, and Robin Brons, among other recent writers. The book-length studies on the issue (since my earlier work) are by Beckwith (Greek Buddha) and Neal (Madhyamaka and Pyrrhonism). Other writers/scholars with relevant expertise include C. W. Huntington, Jr., Charles Goodman, Stephen Batchelor, Dan Lusthaus, Rupert Gethin, and Mark Siderits. -/- . (shrink)

We propose that human self-domestication favored the emergence of a less aggressive phenotype in our species, more precisely phenotype prone to replace (reactive) physical aggression with verbal aggression. In turn, the (gradual) transition to verbal aggression and to more sophisticated forms of verbal behavior favored self-domestication, with the two processes engaged in a reinforcing feedback loop, considering that verbal behavior entails not only less violence and better survival, but also more opportunities to interact longer and socialize with more conspecifics, ultimately (...) enabling the emergence of more complex forms of language. Whereas in the case of self-domestication sexual selection has been proposed to work against physical aggression traits, in the case of verbal insult the selection has been proposed to work in favor of verbal aggression. The tension between these two seemingly opposing forces gets resolved/alleviated by a tendency to replace physical aggression with verbal aggression, and with verbal behavior more generally. This also helps solve the paradox of the Self Domestication Hypothesis regarding aggression, more precisely why aggression in humans has been reduced only when it comes to reactive aggression, but not when it comes to proactive aggression, the latter exhibiting an increase with the advent of modern language. We postulate that this feedback loop was particularly important during the time period before 50 kya, arguably between 200 kya and 50 kya, when humans were not fully modern, neither in terms of their skull/brain morphology and their behavior/culture, nor in terms of their self-domestication. The novelty of our approach lies (i) in giving an active role to early forms of language in interacting with self-domestication processes; (ii) in providing specific linguistic details and functions of this early stage of grammar (including insult and humor); (iii) in supplying neurobiological, ontogenetic, and clinical evidence of a link between (reactive) aggression and (reactive) verbal behavior; (iv) in identifying a variety of proxies of the earlier stages in evolution among cognitive disorders; and (v) in identifying specific points of contact and mutual reinforcement between these two processes (self-domestication and early language evolution), including reduction in physical aggression and stress/tension, as well as sexual selection.

When conceived as an empirical claim, it is natural to wonder how one might test the hypothesis of multiple realization. I consider general issues of testability, show how they apply specifically to the hypothesis of multiple realization, and propose an auxiliary assumption that, I argue, must be conjoined to the hypothesis of multiple realization to ensure its testability. I argue further that Bechtel and Mundale go astray because they fail to appreciate the need for this auxiliary assumption.

By reference to Maxwell's kinetic theory, one feature of hypothetico-deductivism is defended. A scientist need make no inference to a hypothesis when he first proposes it. He may have no reason at all for thinking it is true. Yet it may be worth considering. In developing his kinetic theory there were central assumptions Maxwell made (for example, that molecules are spherical, that they exert contact forces, and that their motion is linear) that he had no reason to believe (...) true. In this paper I develop a position that explains why they were worth considering, and that rejects the retroductive position that a hypothesis is worth considering when, if true, it would explain the observed data.

Many philosophers deny that happiness can be equated with pleasurable experiences. Nozick introduced an experience machine thought experiment to support the idea that happiness requires pleasurable experiences that are “in contact with reality.” In this thought experiment, people can choose to plug into a machine that induces exclusively pleasurable experiences. We test Nozick’s hypothesis that people will reject this offer. We also contrast Nozick’s experience machine scenario with scenarios that are less artificial, and offer options which are less (...) invasive or disruptive than being connected to a machine, specifically scenarios in which people are offered an experience pill or a pill that improves overall functioning.

Darwin had a hypothesis about descent with modification, and a Spencerian view of the evolution as selfish conflict. Biology remains marked by the dualism today. Many, inside the discipline and out, suppose that taking an evolutionary perspective just is to seek the secret selfishness that “explains” a successful form of life. Nowhere is this view of evolution more entrenched than in the theory specialists call Sexual Selection, a theory on the evolution of everything that differentiates the sexes. Darwin thought (...) the conspicuous sexual differences among animals are adaptations to female choice. Down to our day the biology of sexual selection confirms his melodramatic cliches: Males are passionate, armed, and ornamented, females coy and drab, conflict inevitable and ubiquitous. Roughgarden, a professor of biology at Stanford, dismisses sexual selection as “pure ideology.” “A huge body of scientific theory is incorrect.” All the parts that overlook the evolution of real cooperation, meaning not the coincidence of selfish interests, but coordinated collaboration. The evidence of such cooperation between the sexes is diverse, cumulative, and much underappreciated. Roughgarden also takes friendship and pleasure seriously. Intimate contact keeps animals coordinated, and mutual pleasure makes cooperation self-policing, without the punishing algorithms postulated by Evolutionary Psychology. Her book is a serious work of science. She argues that “sexual selection can never be demonstrated once studies are sufficiently thorough,” and shows that this whole area of evolutionary biology “is not settled science, is in considerable flux, and is not ready for export.” If you research any field affected by the claims of Sexual Selection, Evolutionary Psychology, or the Selfish Gene, you may want to study this book.

The so‐called problem of irrelevant conjunction has been seen as a serious challenge for theories of confirmation. It involves the consequences of conjoining irrelevant statements to a hypothesis that is confirmed by some piece of evidence. Following Hawthorne and Fitelson, we reconstruct the problem with reference to Bayesian confirmation theory. Then we extend it to the case of conjoining irrelevant statements to a hypothesis that is dis confirmed by some piece of evidence. As a consequence, we obtain and (...) formally present a novel and more troublesome problem of irrelevant conjunction. We conclude by indicating a possible solution based on a measure‐sensitive approach and by critically discussing a major alternative way to address the problem. *Received December 2008; revised August 2009. †To contact the authors, please write to: Department of Philosophy, University of Turin, via Sant'Ottavio 20, 10124 Turin, Italy; e‐mail: [email protected] ; [email protected] or [email protected].

The cultural norms of traditional societies encourage behavior that is consistent with maximizing reproductive success but those of modern post-demographic transition societies do not. Newson et al (2005) proposed that this might be because interaction between kin is relatively less frequent in modern social networks. Assuming that people’s evaluations of reproductive decisions are influenced by a desire to increase their inclusive fitness, they will be inclined to prefer their kin to make fitness-enhancing choices. Such a preference will encourage the emergence (...) of pronatal cultural norms if social networks are dense with kin. Less pronatal norms will emerge if contact between kin makes up a small proportion of social interactions. This article reports evidence based on role-play studies that supports the assumption of the kin influence hypothesis that evaluations of reproductive decisions are influenced by a desire to increase inclusive fitness. It also presents a cultural evolutionary model demonstrating the long-term effect of declining kin interaction if people are more likely to encourage fitness-enhancing choices when interacting with their kin than with nonrelatives.

Humans have been using fire for hundreds of millennia, creating an ancestral expansion toward the nocturnal niche. The new adaptive challenges faced at night were recurrent enough to amplify existing psychological variation in our species. Night-time is dangerous and mysterious, so it selects for individuals with higher tendencies for paranoia, risk-taking, and sociability. During night-time, individuals are generally tired and show decreased self-control and increased impulsive behaviors. The lower visibility during night-time favors the partial concealment of identity and opens more (...) opportunities for disinhibition of self-interested behaviors. Indeed, individuals with an evening-oriented chronotype are more paranoid, risk-taking, extraverted, impulsive, promiscuous, and have higher antisocial personality traits. However, under some circumstances, such as respiratory pandemics, the psychobehavioral traits favored by the nocturnal niche might be counter-productive, increasing contagion rates of a disease that can evade the behavioral immune system because its disease cues are often nonexistent or mild. The eveningness epidemiological liability hypothesis presented here suggests that during the COVID-19 pandemic, the evening-oriented psychobehavioral profile can have collectively harmful consequences: there is a clash of core tendencies between the nocturnal chronotype and the recent viral transmission-mitigating safety guidelines and rules. The pandemic safety protocols disrupt much normal social activity, particularly at night when making new social contacts is desired. The SARS-CoV-2 virus is contagious even in presymptomatic and asymptomatic individuals, which enables it to mostly evade our evolved contagious disease avoidance mechanisms. A growing body of research has indirectly shown that individual traits interfering with social distancing and anti-contagion measures are related to those of the nocturnal chronotype. Indeed, some of the social contexts that have been identified as superspreading events occur at night, such as in restaurants, bars, and nightclubs. Furthermore, nocturnal environmental conditions favor the survival of the SARS-CoV-2 virus much longer than daytime conditions. We compare the eveningness epidemiological liability hypothesis with other factors related to non-compliance with pandemic safety protocols, namely sex, age, and life history. Although there is not yet a direct link between the nocturnal chronotype and non-compliance with pandemic safety protocols, security measures and future empirical research should take this crucial evolutionary mismatch and adaptive metaproblem into account, and focus on how to avoid nocturnal individuals becoming superspreaders, offering secure alternatives for nocturnal social activities.

Given the contemporary ambivalent standpoints toward the future of artificial intelligence, recently denoted as the phenomenon of Singularitarianism, Gregory Bateson’s core theories of ecology of mind, schismogenesis, and double bind, are hereby revisited, taken out of their respective sociological, anthropological, and psychotherapeutic contexts and recontextualized in the field of Roboethics as to a twofold aim: (a) the proposal of a rigid ethical standpoint toward both artificial and non-artificial agents, and (b) an explanatory analysis of the reasons bringing about such a (...) polarized outcome of contradictory views in regard to the future of robots. Firstly, the paper applies the Batesonian ecology of mind for constructing a unified roboethical framework which endorses a flat ontology embracing multiple forms of agency, borrowing elements from Floridi’s information ethics, classic virtue ethics, Felix Guattari’s ecosophy, Braidotti’s posthumanism, and the Japanese animist doctrine of Rinri. The proposed framework wishes to act as a pragmatic solution to the endless dispute regarding the nature of consciousness or the natural/artificial dichotomy and as a further argumentation against the recognition of future artificial agency as a potential existential threat. Secondly, schismogenic analysis is employed to describe the emergence of the hostile human–robot cultural contact, tracing its origins in the early scientific discourse of man–machine symbiosis up to the contemporary countermeasures against superintelligent agents. Thirdly, Bateson’s double bind theory is utilized as an analytic methodological tool of humanity’s collective agency, leading to the hypothesis of collective schizophrenic symptomatology, due to the constancy and intensity of confronting messages emitted by either proponents or opponents of artificial intelligence. The double bind’s treatment is the mirroring “therapeutic double bind,” and the article concludes in proposing the conceptual pragmatic imperative necessary for such a condition to follow: humanity’s conscience of habitualizing danger and familiarization with its possible future extinction, as the result of a progressive blurrification between natural and artificial agency, succeeded by a totally non-organic intelligent form of agency.

One of the main functions that introductory chemistry courses have fulfilled during the past century has been to provide evidence for the general validity of 'the atomic hypothesis.' A second function has been to demonstrate that an analytical approach has wide applicability in rationalizing many kinds of phenomena. Following R.G. Collingwood, these two functions can be recognized as related to a philosophical 'cosmology' (worldview, weltanshauung) that became dominant in the later Renaissance. Recent developments in many areas of science, and (...) in chemistry, have emphasized the central importance of understanding synthetic, developmental, and evolutionary aspects of nature. This paper argues that these scientific developments, and changes in other aspects of culture, amount to a widespread shift to an alternative cosmology, a quite different general worldview. To the extent that this is the case, introductory chemistry courses ought to be changed in fundamental ways. Rather that having a main focus on analysis to microscopic components, introductory chemistry instruction should emphasize current scientific understanding of the (synthetic) evolutionary origins of the present world. This altered approach would provide good preparation for future professional work, while also making better contact with the perceived concerns of students. (shrink)
