This paper continues a strain of intellectual complaint against the presumptions of certain kinds of formal semantics (the qualification is important) and their bad effects on those areas of artificial intelligence concerned with machine understanding of human language. After some discussion of the use of the term epistemology in artificial intelligence, the paper takes as a case study the various positions held by McDermott on these issues and concludes, reluctantly, that, although he has reversed himself on the issue, there was (...) no time at which he was right.

As philosophers of mind we seem to hold in common no very clear view about the relevance that work in psychology or the neurosciences may or may not have to our own favourite questions—even if we call the subject ‘philosophical psychology’. For example, in the literature we find articles on pain some of which do, some of which don't, rely more or less heavily on, for example, the work of Melzack and Wall; the puzzle cases used so extensively in discussions (...) of personal identity are drawn sometimes from the pleasant exercise of scientific fantasy, at times from surprising reports of scientific fact; and there are those who deny, as well as those who affirm, the importance of the discovery of rapid-eye-movement sleep to the philosophical treatment of dreaming. A general account of the relation between scientific, and philosophical, psychology is long overdue and of the first importance. Here I shall limit myself to just one area where the two seem to connect, discussing one type of neuropsychological research and its relevance to questions in the philosophy of mind and the philosophy of psychology.

A general hypothesis of atom size effects for G.P. zone formation is discussed in this paper and results are presented of precipitation in the systems Fe-Au and Fe-Mo. Techniques used are resistivity measurements and electron microscopy. In the Fe-Mo system it is shown that after initial cluster formation during the early stages of ageing after the quench, further growth ceases and vacancies anneal out into dislocation loops. The activation energy for the initial clustering was 1·3 ev whilst the excess vacancy (...) concentration estimated from the loop area gave a vacancy formation energy of ∼1·5 ev. These results confirm recent quenching results on pure iron. The refusal of Mo zones to grow confirms the general hypothesis of size effects.In the Fe-Au system precipitation of gold platelets after quenching is shown to be associated with the high density of dislocations formed during quenching through the phase transformation of the iron matrix. The effect of the dislocations is shown by the low value of ∼0·5 for the Johnson—Mehl kinetic parameter and by the activation energy for growth which is ∼0·8 of the equilibrium diffusion energy for Au in Fe. As the size-effect hypothesis does not apply to precipitation on dislocations the growth of zones in Fe—Au does not affect its validity. (shrink)

Who is morally permitted to tell jokes about Jews? Poles? Women? Only those in the group? Only those who would be punching up? Anyone, since they are just jokes? All of the standard approaches are too broad or too narrow. In on the Joke provides a more sophisticated approach according to which each person possesses "joke capital" that can serve as "comic insurance" covering certain jokes in certain contexts. When Bob tells a joke about Jews, we can never know exactly (...) what Bob is intending since we cannot see inside Bob’s mind. But we could reasonably infer, if we knew Bob himself was Jewish, if he worked tirelessly for Jewish causes, or was a card-carrying Neo-Nazi. Each would affect his joke capital, and, in certain circumstances, we would have a moral standing to demand to see his ledger to see how much joke capital he had with respect to Jews. The permissibility of that joke depends upon four factors: the joke, the teller of the joke, the audience, and the setting. The view developed in In on the Joke is the only view that clearly explains how each of these components work together in an integrated, effective ethic of humor. (shrink)

Widerspruch gegen Konsens dient der Durchsetzung von Interessen, dem asthetischen Vergnugen und der Verbreitung der Wahrheit. Der Band wirft Schlaglichter auf die Geschichte einer vergessenen Schlusselkategorie von der Klassischen Rhetorik bis zur Romantik. Das Phanomen antikonsensualer Rede wird anhand des Begriffs der Paradoxie untersucht, der heute zumeist den logischen Widerspruch meint, im traditionellen Verstandnis aber eine Rede oder eine These gegen (gr. para) eine allgemeine Meinung (gr. doxa) bezeichnet hat. Dabei werden verschiedene Praktiken antikonsensualer Rede nach ihrer Zwecksetzung und ihrer (...) Formgebung unterschieden, die ihrerseits darauf hinweisen, in welchem Verhaltnis Mensch, Sprache und Wahrheit jeweils gesehen werden. So wird erstmals ein Bogen von sophistischen Schaureden uber moralphilosophische Lehren der Antike und der Renaissance bis hin zu den epochemachenden Aufwertungen des untersuchten Phanomens in Aufklarung und Fruhromantik geschlagen.

Through analysis of film sequences focusing on DNA in two British Broadcasting Corporation nonfiction science television programs, Wonders of Life and Bang! Goes the Theory, first broadcast in 2013, contrasting “religious” and “secular” representations of science are identified. In the “religious” portrayal, immutable scientific knowledge is revealed to humanity by nature with minimal human intervention. Science provides a creation story, “explanatory omnicompetence,” and makes life existentially meaningful. In the “secular” portrayal, scientific knowledge is changeable; is produced through technical skill in (...) expert communities; and is ambiguous, potentially positive and negative for society. Television representations of science affect audience understandings, and this is particularly the case for nonfiction representations of science, as they are likely to be “taken more seriously” than fictional representations. The consequences of the “religious” representation of science are discussed, and it is argued that a widespread understanding of science as presented in the religious portrayal would negatively impact democracy.

Employee misconduct is prevalent in organizations and may be counterproductive in social and material terms. It is thus important to better understand how misconduct is construed by employees and the factors that determine its ethical acceptability in specific cases. This study explores attitudes towards unethical and minor deviant behaviours by examining the degree of acquiescence towards them in a sample of employees. Based on previous studies it was hypothesized that both organizational commitment and job satisfaction would be negatively related to (...) the acceptance of such behaviours in organizational settings. Results show that there is a relationship between the degree of acquiescence and organizational commitment and a more modest relationship with job satisfaction. They further indicate that organizational tenure impacts very significantly on the degree of acceptance. Although differences were found for age, neither gender nor organizational variables were found to be significant. (shrink)

The public interest should be a central ethical concern of members of the computer profession, and this would also result in the social status and power of software engineers being augmented. One attractive means to encourage and enforce ethical standards on the part of engineers and employers would be a system of licensing by internationally recognised professional bodies whose legitimacy stems from their capacity to act in the public interest.

By formalizing recent syntactic theories for natural languages Stabler shows how their complexity can be handled without guesswork or oversimplification. By formalizing recent syntactic theories for natural languages in the tradition of Chomsky's Barriers, Stabler shows how their complexity can be handled without guesswork or oversimplification. He introduces logical representations of these theories together with special deductive techniques for exploring their consequences that will provide linguists with a valuable tool for deriving and testing theoretical predictions and for experimenting with alternative (...) formulations of grammatical principles. Stabler's novel approach allows results to be deduced with straightforward calculations and provides a systematic framework for tackling the problem of how speakers can infer the properties of an utterance from principles of the grammar. The special treatment of equality, induction principles, and inclusion of a general method for collecting structures from proofs means that sophisticated linguistic arguments can be carried out in detail, giving a rich perspective to issues in linguistic theory and parsing.

Correspondence should be addressed to David A. Leopold [email protected] the viewing of certain patterns, widely known as ambiguous or puzzle figures, perception lapses into a sequence of spontaneous alternations, switching every few seconds between two or more visual interpretations of the stimulus. Although their nature and origin remain topics of debate, these stochastic switches are generally thought to be the automatic and inevitable consequence of viewing a pattern without a unique solution. We report here that in humans such perceptual alternations (...) can be slowed, and even brought to a standstill, if the visual stimulus is periodically removed from view. We also show, with a visual illusion, that this stabilizing effect hinges on perceptual disappearance rather than on actual removal of the stimulus. These findings indicate that uninterrupted subjective perception of an ambiguous pattern is required for the initiation of the brain-state changes underlying multistable vision.Visual perception involves coordination between sensory sampling of the world and active interpretation of the sensory data. Human perception of objects and scenes is normally stable and robust, but it falters when one is presented with patterns that are inherently ambiguous or contradictory. Under such conditions, vision lapses into a chain of continually alternating percepts, whereby a viable visual interpretation dominates for a few seconds and is then replaced by a rival interpretation. This multistable vision, or 'multistability', is thought to result from destabilization of fundamental visual mechanisms, and has offered valuable insights into how sensory patterns are actively organized and interpreted in the brain1, 2. Despite a great deal of recent research and interest in multistable perception, however, its neurophysiological underpinnings remain poorly understood. Physiological studies have suggested that disambiguation of ambiguous patterns. (shrink)

This book explores the scope and limits of the concept of personDS a vexed question in contemporary philosophy. The author begins by questioning the methodology of thought-experimentation, arguing that it engenders inconclusive and unconvincing results, and that truth is stranger than fiction. She then examines an assortment of real-life conditions, including infancy, insanity andx dementia, dissociated states, and split brains. The popular faith in continuity of consciousness, and the unity of the person is subjected to sustained criticism. The author concludes (...) with a look at different views of the person found in Homer, Aristotle, the post-Cartesians, and contemporary cognitive science. (shrink)

Grey parrots do not acquire referential English labels when tutored with videotapes displayed on CRT screens if socially isolated, reward for attempted labels is possible, trainers direct birds’ attention to the monitor, live video feed avoids habituation or one trainer repeats labels produced on video and rewards label attempts. Because birds learned referential labels from live tutor pairs in concurrent sessions, we concluded that video failed because input lacked live social interaction and modeling. Recent studies, however, suggest that standard CRT (...) monitor flickering could instead have prevented learning. Using an LCD monitor, we found that eliminating flickering did not enable birds to learn from video under conditions of limited social interaction. Results emphasize the role of social interaction in referential label learning and may generalize to other systems. (shrink)

This paper discusses the reception and impact of Berger and Luckmann’s The Social Construction of Reality. The article will, first, address Berger and Luckmann themselves and their approach to the book. In the next part, we will sketch the diffusion of the basic concept of the book. Then we want to show that the reception exhibits a particular open form, which allowed it to disperse into extremely different disciplines not only of the social sciences and the humanities. It is the (...) disciplinary distance in particular that detaches the diffusion of the concept from reference to the book. In the next part, we can see that this detachment leads to the variation of approaches to social construction. Particularly, it is the misidentification with constructivism that leads to misunderstandings, which will then be clarified in contrast to our reconsideration of the basic thesis of SCR. The conclusion will state that Berger and Luckmann’s concept therefore constitutes the common denominator of social constructivist approaches. (shrink)

This article discusses the extension of ViewGen, an algorithm derived for belief ascription, to the areas of intensional object identification and metaphor. ViewGen represents the beliefs of agents as explicit, partitioned proposition sets known as environments. Environments are convenient, even essential, for addressing important pragmatic issues of reasoning. The article concentrates on showing that the transformation of information in metaphors, intensional object identification, and ordinary, nonmetaphorical belief ascription can all be seen as different manifestations of a single environment-amalgamation process. The (...) article also briefly discusses the extension of ViewGen to speech-act processing and the addition of a heuristic-based relevance-determination procedure, and justifies the partitioning approach to belief ascription.

Background: Continuous viewing of ambiguous patterns is characterized by wavering perception that alternates between two or more equally valid visual solutions. However, when such patterns are viewed intermittently, either by repetitive presentation or by periodic closing of the eyes, perception can become locked or "frozen" in one configuration for several minutes at a time. One aspect of this stabilization is the possible existence of a perceptual memory that persists during periods in which the ambiguous stimulus is absent. Here, we use (...) a novel paradgim of temporally interleaved ambiguous stimuli to explore the nature of this memory, with particular regard to its potential impact on perceptual organization. Results: We found that the persistence of a perceptual configuration was robust to interposed visual patterns and, further, that at least three ambiguous patterns, when interleaved in time, could undergo parallel, stable time courses. Then, using an interleaved presentation paradigm, we established that the occasional reversal in one pattern could be coupled with that of its interleaved counterpart, and that this coupling was a function of the structural similarity between the patterns. Conclusions: We postulate that the stabilization observed with repetitive presentation of ambiguous patterns can be at least partially accounted for by processes that retain a recent perceptual interpretation, and we speculate that such memory may be important in natural vision. We further propose tha the interleaved paradigm introduced here may be of great value to gauge aspects of stimulus similarity that appeal to particular mechanisms of perceptual organization.

O fenômeno da desinformação tem tomado centralidade no debate público nos últimos tempos. As discussões e ações de combate a conteúdos desinformativos têm sido impulsionadas pelos mais diversos setores da sociedade, motivadas, sobretudo, pela massificação da produção, circulação e consumo de fake news. Entretanto, a desinformação não se restringe apenas ao ambiente da circulação de notícias falsas por pseudo mídias jornalísticas, nem tampouco se caracteriza como um fenômeno novo. É possível remontar outros contextos históricos onde o viés desinformativo tem sido (...) utilizado como política de Estado, estratégia de guerra e produção de consenso em torno de verdades anunciadas. Nesse sentido, o que torna a desinformação um problema tão urgente e atual? Buscando responder essa questão nossa proposta parte de uma discussão teórico-analítica ancorada em uma perspectiva marxiana de economia política. Para tanto, iremos operar com duas noções que consideramos essenciais para elucidar essa questão, sendo elas: a lógica do Capital Informação e a noção de valor no ambiente de uma economia política das plataformas sócio-digitais.

This outstanding collection is designed to address the fundamental issues and principles underlying the task of Artificial Intelligence.

A relação informação e capital tem sido vital para a produção do habitus informacional no século XXI, seja pelo cada vez maior trânsito de usuários interconectados à grande rede, seja pela massificação da produção de artefatos infocomunicacionais que possibilitam a manutenção desse fluxo. Sob o ponto de vista econômico, a informação é a matéria que passa a estruturar a lógica de organização do capital, e, por conseguinte, também a ordem social, política e cultural das sociedades contemporâneas. Desse modo, é na (...) atual vigência do capital, entendido aqui como capital-informação, que vimos emergir o modelo de negócios da economia das plataformas sócio-digitais amparado na cultura algorítmica, no paradigma comunicacional todos-todos e na mineração constante de dados de usuários. Esse modelo altamente lucrativo tem sido apontado como um dos principais responsáveis pela disseminação massiva de conteúdo desinformativo através do fenômeno das fake news, regime de pós-verdade, propensão a formação de filtros-bolha, câmaras de eco, cultura do cancelamento e disseminação de ódio nas infovias. Com isso, neste trabalho buscamos problematizar a noção de informação tóxica como reflexo de um ambiente informacional pautado pela toxicidade, virulência, sectarismo, polarização e predisponência a violência digital como dispositivos que tem perfilado o comportamento dos indivíduos nas redes e fora delas, evocando velhos estigmas, preconceitos, perseguições e falsas crenças direcionadas a grupos e indivíduos considerados material e simbolicamente como ameaças. Conclui-se assim, que a informação tóxica é um desafio a ordem democrática e civilizatória, constituindo-se como um sintoma de uma sociedade adoecida, bem como uma mercadoria de altos rendimentos na sociedade do capital-informação.
