In his bestselling work of popular science, Sir Roger Penrose takes us on a fascinating roller-coaster ride through the basic principles of physics, cosmology, mathematics, and philosophy to show that human thinking can never be emulated by a machine.

This paper is a plea for hedonism to be taken more seriously. It begins by charting hedonism's decline, and suggests that this is a result of two major objections: the claim that hedonism is the 'philosophy of swine', reducing all value to a single common denominator, and Nozick's 'experience machine' objection. There follows some elucidation of the nature of hedonism, and of enjoyment in particular. Two types of theory of enjoyment are outlined-intemalism, according to which enjoyment has some special 'feeling (...) tone'. and externalism, according to which enjoyment is any kind of experience to which we take some special attitude, such as that of desire. lnternalism-the traditional view--is defended against current externalist orthodoxy. The paper ends with responses to the philosophy of swine and the experience machine objections. (shrink)

This paper introduces a special issue of Cognitive Science initiated on the 25th anniversary of the publication of Parallel Distributed Processing (PDP), a two-volume work that introduced the use of neural network models as vehicles for understanding cognition. The collection surveys the core commitments of the PDP framework, the key issues the framework has addressed, and the debates the framework has spawned, and presents viewpoints on the current status of these issues. The articles focus on both historical roots and contemporary (...) developments in learning, optimality theory, perception, memory, language, conceptual knowledge, cognitive control, and consciousness. Here we consider the approach more generally, reviewing the original motivations, the resulting framework, and the central tenets of the underlying theory. We then evaluate the impact of PDP both on the field at large and within specific subdomains of cognitive science and consider the current role of PDP models within the broader landscape of contemporary theoretical frameworks in cognitive science. Looking to the future, we consider the implications for cognitive science of the recent success of machine learning systems called “deep networks”—systems that build on key ideas presented in the PDP volumes.

"Roger-Pol Droit's book is a reassessment of our day-to-day engagement with life. In 101 short texts, Droit invites us to reconsider our most ordinary actions as unexpected philosophical events: peeling an apple, trying to lie in a hammock, watching someone sleep, hearing your voice on an answering machine, playing with a small child - activities that, when considered outside of their routine, invite us to experience the familiar in startling new ways. Droit encouarges us to go further: pretend to (...) be an animal of your choice, create a wall with your hands, try to walk around your room in total darkness, spend time in the Underground - and observe your oddity."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

This paper investigates how the simulation of intelligence, an activity that has been considered the notional task of Artificial Intelligence, does not comprise its duplication. Briefly touching on the distinction between conceivability and possibility, and commenting on Ryan’s approach to fiction in terms of the interplay between possible worlds and her principle of minimal departure, we specify verisimilitude in Artificial Intelligence as the accurate resemblance of intelligence by its simulation and, from this characterization, claim the metaphysical impossibility of duplicating intelligence, (...) as neither verisimilarly nor convincingly simulating intelligence involves its duplication. To this end, we argue by a representative case of simulation that, albeit conceivable, Turing’s test for machine intelligence wrongly equates the occurrence of indistinguishable intelligence performance to intelligence duplication, which is grounded in a prima facie conceivable but metaphysically impossible view that separates intelligence from its origin. Finally, we establish the following criterion for evaluating simulation in Artificial Intelligence: simulations succeed in AI if and only if they are able to epistemically persuade human beings that intelligence has been duplicated, that is, if and only if verisimilar simulations can convincingly minimally depart from actual intelligence.

Il n'y a pas si longtemps, la philosophie paraissait dépassée. Le triomphe des techniques et des sciences semblait l'avoir reléguée dans un coin obscur, comme un accessoire inutile. La situation est aujourd'hui tout autre : un besoin de philosophie commence à se manifester. Dans des pays extrêmement divers, un regain d'intérêt est perceptible. Parmi ses causes : l'exigence d'une nouvelle réflexion éthique, la croissance de jeunes démocraties, la diffusion des débats intellectuels, la nécessité d'une maîtrise humaine des machines. Aucune vue (...) d'ensemble n'était disponible. L'UNESCO a repris, à l'occasion de son 50e anniversaire, un de ses projets fondateurs : organiser une enquête mondiale sur la place actuelle de la philosophie dans l'éducation et dans la culture. Principaux constats : l'enseignement philosophique est généralement une création récente, très disparate d'un pays à l'autre, valorisée dans les discours, négligée dans les faits. Principale constance : philosophie et démocratie ont partie liée et semblent progresser l'une par l'autre. Cette synthèse repose sur une documentation exceptionnelle, constituée par des centaines de documents en provenance de plusieurs dizaines d'Etats, de multiples propositions pratiques élaborée au cours de réunions internationales, des documents de travail spécifiques rédigés par des experts (multimédia, citoyenneté, économie...), etc. Les lignes de force qui se dégagent de cette masse de données sont exposées ici de manière simple et claire. Dans un monde qui devient chaque jour à la fois plus interdépendant et plus morcelé, il est probable qu'une véritable éducation philosophique soit déjà un des enjeux de la liberté. (shrink)

The presence of vegetation on railway tracks threatens track safety and longevity. However, vegetation inspections in Sweden are currently being carried out manually. Manually inspecting vegetation is very slow and time consuming. Maintaining an even quality standard is also very difficult. A machine vision-based approach is therefore proposed to emulate the visual abilities of the human inspector. Work aimed at detecting vegetation on railway tracks has been split into two main phases. The first phase is aimed at detecting vegetation on (...) the tracks using appropriate image analysis techniques. The second phase is aimed at detecting the rails in the image to determine the cover of vegetation that is present between the rails as opposed to vegetation present outside the rails. Results achieved in the current work indicate that the machine vision approach has performed reasonably well in detecting the presence/absence of vegetation on railway tracks when compared with a human operator.

Most empirical work in human categorization has studied learning in either fully supervised or fully unsupervised scenarios. Most real-world learning scenarios, however, are semi-supervised: Learners receive a great deal of unlabeled information from the world, coupled with occasional experiences in which items are directly labeled by a knowledgeable source. A large body of work in machine learning has investigated how learning can exploit both labeled and unlabeled data provided to a learner. Using equivalences between models found in human categorization and (...) machine learning research, we explain how these semi-supervised techniques can be applied to human learning. A series of experiments are described which show that semi-supervised learning models prove useful for explaining human behavior when exposed to both labeled and unlabeled data. We then discuss some machine learning models that do not have familiar human categorization counterparts. Finally, we discuss some challenges yet to be addressed in the use of semi-supervised models for modeling human categorization. (shrink)

COVID-19, the most severe public health problem to occur in the past 10 years, has greatly impacted people's mental health. Colleges in China have reopened, and how to prevent college students from suffering secondary damage due to school reopening remains elusive. This cross-sectional study was aimed to evaluate the psychological impact of COVID-19 after school reopening and explore via machine learning the factors that influence anxiety and depression among students. Among the 478 valid online questionnaires collected between September 14th and (...) September 20th, 74 showed symptoms of anxiety, and 155 showed symptoms of depression. Descriptive analysis of basic personal characteristics indicated that students at a higher grade, having relatives or friends who have been infected, fearing being infected, and having a pessimistic attitude to COVID-19 easily experience anxiety or depression. The Synthetic Minority Oversampling Technique was utilized to counteract the imbalance of retrieved data. The Akaike Information Criterion and multivariate logistic regression were performed to explore significant influence factors. The results indicate that exercise frequency, alcohol use, school reopening, having relatives or friends who have been infected, self-quarantine, quarantine of classmates, taking temperature routinely, wearing masks routinely, sleep quality, retaining holiday, availability of package delivery, take-out availability, lockdown restriction, several areas in school closed due to COVID-19, living conditions in the school, taking the final examinations after school reopening, and the degree to which family economic status is influenced by COVID-19 are the primary influence factors for anxiety or depression. To evaluate the effect of our model, we used 5-fold cross-validation, and the average area under the curve values of the receiver operating characteristic curves of anxiety and depression on the test set reached 0.885 and 0.806, respectively. To conclude, we examined the presence of anxiety and depression symptoms among Chinese college students after school reopening and explored many factors influencing students' mental health, providing reasonable school management suggestions.

This article examines the emerging possibility of “brain-state transitioning,” in which one brain state is prompted through manipulating the dynamics of the active brain. The technique, still in its infancy, is intended to provide the basis for novel treatments for brain-based disorders. Although a detailed literature exists covering topics around brain-machine interfaces, where targets of brain-based activity include artificial limbs, hardware, and software, there is less concentration on the brain itself as a target for instrumental intervention. This article examines some (...) of the science behind brain-state transitioning, before extending beyond current possibilities in order to explore philosophical and ethical questions about how transitions could be seen to impact on assessment of responsibility and personal identity. It concludes with some thoughts on how best to pursue this nascent approach while accounting for the philosophical and ethical issues. (shrink)

In his stimulating book SHADOWS OF THE MIND, Roger Penrose presents arguments, based on Gödel's theorem, for the conclusion that human thought is uncomputable. There are actually two separate arguments in Penrose's book. The second has been widely ignored, but seems to me to be much more interesting and novel than the first. I will address both forms of the argument in some detail. Toward the end, I will also comment on Penrose's proposals for a "new science of consciousness".

Whether it was John Searle’s Chinese Room argument (Searle, 1980) or Roger Penrose’s argument of the non-computable nature of a mathematician’s insight – an argument that was based on Gödel’s Incompleteness theorem (Penrose, 1989), we have always had skeptics that questioned the possibility of realizing strong Artificial Intelligence (AI), or what has become known by Artificial General Intelligence (AGI). But this new book by Landgrebe and Smith (henceforth, L&S) is perhaps the strongest argument ever made against strong AI. It (...) is a very extensive review of what building a mind essentially amounts to drawing on insights and results from biology, physics, linguistics, computability, philosophy, and mathematics.

ABSTRACTDiffraction gratings are famously associated with Henry Rowland of Johns Hopkins University but there were precursors. Although gratings were first made and used in Europe, reliable machines for ruling gratings were developed in the USA, and two men, Lewis Rutherfurd and William Rogers, tackled the problem before Rowland. Rutherfurd, a wealthy independent astronomer, designed and built the first screw-operated engine for ruling diffraction gratings, the fore-runner of almost all subsequent ruling engines. With it he and his assistant D. C. Chapman (...) ruled many gratings which he generously distributed to practising scientists, thereby materially advancing the science of spectroscopy. Rogers was a Harvard astronomer who developed an interest in the ruling of fine lines on glass that led him to construct a ruling engine with which he investigated the causes of the errors in the rulings he had examined. He continued to seek improvements with a second engine designed for ruling diffraction gratings. He ceased developing this engine when Rowland’s excellent gratings began to be available, concentrating instead on related problems to which he could apply the knowledge and skills he had gained, but his investigations assisted Rowland and other later ruling engine builders. This paper brings together what is known about the ruling engines of Rutherfurd and Rogers, their development, the gratings they produced, their quality and the work that was done with them, and assesses and compares their achievements and the impacts of the work of these two men.

This piece continues the tradition of arguments by John Lucas, Roger Penrose and others to the effect that the human mind is not a machine. Kurt Gödel thought that the intensional paradoxes stand in the way of proving that the mind is not a machine. According to Gödel, a successful proof that the mind is not a machine would require a solution to the intensional paradoxes. We provide what might seem to be a partial vindication of Gödel and show (...) that if a particular solution to the intensional paradoxes is adopted, one can indeed give an argument to the effect that the mind is not a machine.

This paper presents, from a historical and logical-philosophical perspective, the Gödelian arguments of two Oxford scholars, John Lucas and Roger Penrose. Both have been based on Gödel's Theorem to refute mechanism, computationalism and the possibility of creating an AI capable of simulating or duplicating the human mind. In the conclusions, the growing application of empirical methods in mathematics is mentioned and a possible path that would support Lucas and Penrose's arguments is speculated.

In a recent issue of The Lancet, the historian Roger Cooter predicted that the field of bioethics will soon die of self-inflicted wounds. “Conspiring against it,” he wrote, “is exposure of the funding of some of its US centres by pharmaceutical companies; exclusion of alternative perspectives from the social sciences; retention of narrow analytical notions of ethics in the face of popular expression and academic respect for the place of emotions; divisions within the discipline ; and collusion with, and (...) appropriation by, clinical medicine.” Cooter's prognosis? “Hardly wet behind the ears, bioethics seems destined for a short lifespan.”.

The diagnosis of a new geological epoch, The ‘Anthropocene’, has implications far beyond geological science. If human activity has disrupted the planet, then this diagnosis potentially disrupts socio-political conventions. This article assesses the implications the Anthropocene has for democratic politics, by delineating three challenges: challenges of knowledge, time and boundary. In contrast to the claim that democratic institutions are unable to adequately respond to these challenges, I suggest that they might be strengthened through an engagement with them. Following an ‘agonistic’ (...) understanding of politics, I argue that the contestation instigated by the challenges of the Anthropocene is key to democratic renewal. Just as democracy in the Anthropocene can be enhanced through an agonistic approach, agonistic theory can be enriched through an engagement with the Anthropocene. (shrink)

This paper provides a series of reflections on making the case to senior leaders for the introduction of clinical ethics support services within a UK hospital Trust at a time when clinical ethics committees are dwindling in the UK. The paper provides key considerations for those building a case for clinical ethics support within hospitals by drawing upon published academic literature, and key reports from governmental and professional bodies. We also include extracts from documents relating to, and annual reports of, (...) existing clinical ethics support within UK hospitals, as well as extracts from our own proposal submitted to the Trust Board. We aim for this paper to support other ethicists and/or health care staff contemplating introducing clinical ethics support into hospitals, to facilitate the process of making the case for clinical ethics support, and to contribute to the key debates in the literature around clinical ethics support. We conclude that there is a real need for investment in clinical ethics in the UK in order to build the evidence base required to support the wider introduction of clinical ethics support into UK hospitals. Furthermore, our perceptions of the purpose of, and perceived needs met through, clinical ethics support needs to shift to one of hospitals investing in their staff. Finally, we raise concerns over the optional nature of clinical ethics support available to practitioners within UK hospitals. (shrink)

This article, taking a social semiotic approach, analyses two pieces of music written, shared and exalted by two pre-1945 European fascist movements – the German NSDAP and the British Union of Fascists. These movements, both political and cultural, employed mythologies of unity, common identity and purpose in order to elide the realities of social distinction and political–economic inequalities between bourgeois and proletarian groups in capitalist societies. Visually and inter-personally, the fascist cultural project communicated a machine-like certainty about a vision for (...) a new society based on discipline, conformity and the might of the nation. In this article, we are interested in the ways that these very same discourses are also communicated through sound and music in two songs: The Horst Wessel Lied and the BUF marching song, two songs that used the same melody. We analyse the discourses communicated by the semiotic choices made in melody, arrangements, sound qualities, rhythms as well as in lyrics. The article first identifies some of the underlying semiotic resources for meaning making in sound and then shows how these are used in order to communicate specific ideas, values and attitudes.

In this article, we carry out a Multimodal Critical Discourse Analysis of a sample from a larger corpus of Romanian news articles that covered the controversial camp evictions and repatriation of Romanian Roma migrants from France that began in 2010 and continue to the time of writing in 2017. These French government policies have been highly criticized both within France and by international political and aid organizations. However, the analysis shows how these brutal, anti-humanitarian events became recontextualized in the Romanian (...) Press to represent the French government’s actions as peaceful and consensual. In addition, the demonization of the Roma in the press serves as a strategy to continuously disassociate them from their Romanian counterparts. While there is a long history of discrimination against the Roma in Romania, these particular recontextualizations can be understood in the context of the Romanian government’s need to gloss over its failure to comply with the Schengen accession requirements and acquire full European Union membership.

The ability of very wealthy individuals (or, as I will call them, the ‘super-rich’) to turn their economic power into political power has been—and remains—an important cause of political inequality. In response, this paper advocates an original solution. Rather than solving the problem through implementing a comprehensive conception of political equality, or through enforcing complex rules about financial disclosure etc., I argue that we should impose a choice on the super-rich. The super-rich must choose between (i) forfeiting the things that (...) make them super-rich, i.e., pay a 100 % tax on their wealth above a certain level, or, (ii) they must forfeit some of their political rights. These rights include entitlements to fund political parties; to stand for office; and to work or volunteer for political parties. The right to vote, though, is not limited. I defend my proposal against non-consequentialist and consequentialist objections. I also argue that it avoids two problems that many attempts to reduce political inequality face; these are the political egalitarian’s dilemma and the problem of political equality’s relative moral importance.

Democracy can be a means to independently valuable ends and/or it can be intrinsically (or non-instrumentally) valuable. One powerful non-instrumental defence of democracy is based on the idea that only it can publicly justify political authority. I contend that this is an argument about the reasonable acceptability of political authority and about the requirements of publicity and that satisfying these requirements has nothing to do with whether a society is democratic or not. Democracy, then, plays no role in publicly justifying (...) political authority. I also show that any non-instrumental defence of democracy must make claims about what justice requires and make several further claims that require substantial justification. (shrink)

While there has been extensive work on the textual realizations of climate change in the media, there has been little on the way such discourses are realized and promoted visually. This article addresses this using Multimodal Critical Discourse Analysis to examine a new collection of images from the globally operating Getty Images intended for use in promotions, advertisements and editorials. Getty is promoting this collection in terms of Green Issues being a `marketing opportunity'. In this article we consider the results (...) of these issues being recontextualized through this process, where they are shaped to fit the culture of branding. Analysis is of the images and the search terms where Getty lay out what can be said with the images. (shrink)

There has been criticism of how Fair-Trade products represent workers in remote parts of the world where packaging offers an encounter with distant others which romanticizes and homogenizes them as a pre-modern form of ethnicity. Such workers are shown as always engaged in authentic, simple, honest decontextualized manual labor. And they are depicted as highly appreciative of, and empowered by, the act of ethical shopping. This paper shows that a close social semiotic analysis of Fair-Trade packaging reveals a different set (...) of meanings which sit alongside the decontextualized ones. Designs integrate these workers into more contemporary kinds of modernist, rational, design chic, which communicates its own kind of honesty and authenticity. We consider how this, too, shapes how such consumers encounter distant others and its consequence for the meaning of the act of ethical shopping, where consumers can buy into moral alignment offered by products.

Clinical ethics can be viewed as a practical discipline that provides a structured approach to assist healthcare practitioners in identifying, analysing and resolving ethical issues that arise in practice. Clinical ethics can therefore promote ethically sound clinical and organisational practices and decision-making, thereby contributing to health organisation and system quality improvement. In order to develop students’ decision-making skills, as well as prepare them for practice, we decided to introduce a clinical ethics strand within an undergraduate medical curriculum. We designed a (...) programme of clinical ethics activities for teaching and assessment purposes that involved using ethical frameworks to analyse hypothetical and real-life cases in uni- and inter- professional groups. In this paper, we draw on medical student feedback collected over 6 years to illustrate the appeal to students of learning clinical ethics. We also outline the range of benefits for students, healthcare organisations, and the field of clinical ethics arising from tomorrow’s doctors experiencing clinical ethics early in their training. We conclude by briefly reflecting on how including clinical ethics within tomorrow’s doctors curricular can secure and continue future engagement in clinical ethics support services in the UK, alongside the dangers of preparing students for organisational cultures that might not exist. We anticipate the findings presented in the paper will contribute to wider debates examining the impact of ethics teaching, and its ability to inform future doctors’ practice. (shrink)

It has been recently demonstrated that yeast cells are able to partially regress chromosome segregation in telophase as a response to DNA double‐strand breaks (DSBs), likely to find a donor sequence for homology‐directed repair (HDR). This regression challenges the traditional concept that establishes anaphase events as irreversible, hence opening a new field of research in cell biology. Here, the nature of this new behavior in yeast is summarized and the underlying mechanisms are speculated about. It is also discussed whether it (...) can be reproduced in other eukaryotes. Overall, this work brings forwards the need of understanding how cells attempt to repair DSBs when transiting the latest stages of mitosis, i.e., anaphase and telophase. (shrink)

This article argues against the claim that democracy is a necessary condition of political legitimacy. Instead, I propose a weaker set of conditions. First, I explain the case for the necessity of democracy. This is that only democracy can address the ‘egalitarian challenge’, i.e. ‘if we are all equal, why should only some of us wield political power?’. I show that if democracy really is a necessary condition of political legitimacy, then (what I label) the problems of domestic justice and (...) of international legitimacy become intractable. I then argue that the egalitarian challenge is addressed where the requirements of (1) horizontal equality, (2) acceptable vertical inequality, and (3) publicity, are met and where (4) citizens have some institutionalized opportunity for a voice in decisions. I show that these conditions can be realized in non-democratic form and conclude by explaining how the four conditions can be employed to make the problems of domestic justice and of international legitimacy more tractable. Overall, my ambitions are limited. I do not offer an all-things-considered case against democracy but I do show that (some) forms of non-democratic government are permissible. (shrink)

Deemed consent legislation for deceased organ donation was introduced in England in 2020, and is considered a vital part of the new UK NHS Blood and Transplant’s 10-year strategy to increase consent for organ donation. Despite the legislation containing safeguards to protect the public, the introduction of deemed consent creates ethical, psychological and social un/certainties for healthcare professionals in their practice. In this paper, we offer insights into healthcare professionals’ perspectives on deemed consent, drawn from interview data with 24 healthcare (...) professionals in an NHS Trust in England, prior to the introduction of the legislation. Whilst participants supported deemed consent in principle, they were concerned that it would present a threat to the nature of donation as a ‘gift’; the notion of informed consent (or non-consent); and the autonomy of donors, their relatives, and their own roles as health professionals, posing dilemmas for practice. We argue that healthcare professionals present themselves as guardians of potential (non)donors and thus as having ethics and integrity in their own practice. We draw conclusions around the values and principles that matter to healthcare professionals when contemplating consent in deceased donation which will be useful for organ donation committees and ethics forums.

The United Nations ‘Transforming our world: the 2030 Agenda for Sustainable Development’ lays out 17 Sustainable Development Goals to address a range of global issues related to the future of the planet and human well-being. Critics, however, argue that the Agenda, a complex product of multi-stakeholder governance, in its drive to accommodate many competing voices, is overloaded with weakly defined, overlapping and contradictory issues, concepts and buzzwords. These serve to gloss over actual concrete global problems and forces, concealing an underlying (...) free-trade ideology. In this paper, using Multimodal Critical Discourse Analysis, we draw attention to the nature of the documents used to communicate the Agenda. These documents comprise an edifice of self-referential texts that rely heavily on infographics, bullet points, charts and tables. Such formats appear to helpfully simplify, distil information and break things down into workable components. But, we show, through the affordances of these formats, the the vagueness of buzzwords, contradictions and lack of clear causalities can be glossed over, presenting the Agenda as a highly technical, engaging, and above all moral process. These formats are important, therefore, for the legitimization and rhetorical power of the Agenda, necessary for its take-up by governments and organizations around the world. (shrink)
