Connectionist models provide a promising alternative to the traditional computational approach that has for several decades dominated cognitive science and artificial intelligence, although the nature of connectionist models and their relation to symbol processing remains controversial. Connectionist models can be characterized by three general computational features: distinct layers of interconnected units, recursive rules for updating the strengths of the connections during learning, and “simple” homogeneous computing elements. Using just these three features one can construct surprisingly elegant and powerful models of (...) memory, perception, motor control, categorization, and reasoning. What makes the connectionist approach unique is not its variety of representational possibilities or its departure from explicit rule-based models, or even its preoccupation with the brain metaphor. Rather, it is that connectionist models can be used to explore systematically the complex interaction between learning and representation, as we try to demonstrate through the analysis of several large networks.

What are the philosophical views of professional philosophers, and how do these views change over time? The 2020 PhilPapers Survey surveyed around 2000 philosophers on 100 philosophical questions. The results provide a snapshot of the state of some central debates in philosophy, reveal correlations and demographic effects involving philosophers' views, and reveal some changes in philosophers' views over the last decade.

The scope of noninvasive prenatal testing (NIPT) could expand in the future to include detailed analysis of the fetal genome. This will allow for the testing for virtually any trait with a genetic contribution, including “non-medical” traits. Here we discuss the potential use of NIPT for these traits. We outline a scenario which highlights possible inconsistencies with ethical decision-making. We then discuss the case against permitting these uses. The objections include practical problems; increasing inequities; increasing the burden of choice; negative (...) impacts on the child, family, and society; and issues with implementation. We then outline the case for permitting the use of NIPT for these traits. These include arguments for reproductive liberty and autonomy; questioning the labeling of traits as “non-medical”; and the principle of procreative beneficence. This summary of the case for and against can serve as a basis for the development of a consistent and coherent ethical framework. (shrink)

The second volume in the Pittsburgh Series in the Philosophy of Science, this collection of papers covers a wide range of topics: the development of Newton's First Law comes under scrutiny in papers by Hanson and Ellis; Putnam attempts to clarify certain conceptual issues at the foundations of quantum theory; David Hawkins discusses the relation of teleology and thermodynamics from a neo-Aristotelian viewpoint; Morrison examines certain topics in astronomy; empiricism is studied by Feyerabend from a number of aspects, (...) and is found wanting; finally, Rescher looks at the connections of ethical principles and scientific research, with special reference to the goals, means, and standards of proof, and the dissemination of results of the latter. On the whole, a worthy successor to the first volume, just as certain to raise interest within diverse areas of philosophy.—P. J. M. (shrink)

This study uses a “science pipeline” model and cross-national data to examine women's participation in science education and occupations in seven countries. Gender stratification in later science education and in science occupations is found in every country examined. Young women's participation in science education decreases with each stage in the science pipeline, but there is considerable cross-national variation in the extent of gender stratification in science. Findings show greater gender stratification in science occupations than in science education, suggesting factors other (...) than training help maintain inequality in high-status science occupations.

What happens when machines become more intelligent than humans? One view is that this event will be followed by an explosion to ever-greater levels of intelligence, as each generation of machines creates more intelligent machines in turn. This intelligence explosion is now often known as the “singularity”. The basic argument here was set out by the statistician I.J. Good in his 1965 article “Speculations Concerning the First Ultraintelligent Machine”: Let an ultraintelligent machine be defined as a machine that can far (...) surpass all the intellectual activities of any man however clever. Since the design of machines is one of these intellectual activities, an ultraintelligent machine could design even better machines; there would then unquestionably be an “intelligence explosion”, and the intelligence of man would be left far behind. Thus the first ultraintelligent machine is the last invention that man need ever make. The key idea is that a machine that is more intelligent than humans will be better than humans at designing machines. So it will be capable of designing a machine more intelligent than the most intelligent machine that humans can design. So if it is itself designed by humans, it will be capable of designing a machine more intelligent than itself. By similar reasoning, this next machine will also be capable of designing a machine more intelligent than itself. If every machine in turn does what it is capable of, we should expect a sequence of ever more intelligent machines. This intelligence explosion is sometimes combined with another idea, which we might call the “speed explosion”. The argument for a speed explosion starts from the familiar observation that computer processing speed doubles at regular intervals. Suppose that speed doubles every two years and will do so indefinitely. Now suppose that we have human-level artificial intelligence 1 designing new processors. Then faster processing will lead to faster designers and an ever-faster design cycle, leading to a limit point soon afterwards. The argument for a speed explosion was set out by the artificial intelligence researcher Ray Solomonoff in his 1985 article “The Time Scale of Artificial Intelligence”.1 Eliezer Yudkowsky gives a succinct version of the argument in his 1996 article “Staring at the Singularity”: “Computing speed doubles every two subjective years of work..

Working memory is the system responsible for maintaining and manipulating information, in the face of ongoing distraction. In turn, WM span is perceived to be an individual-differences construct reflecting the limited capacity of this system. Recently, however, there has been some evidence to suggest that WM capacity can increase through training, raising the possibility that training can functionally alter the neural structures supporting WM. To address the hypothesis that the neural substrates underlying WM are targeted by training, we conducted a (...) meta-analysis of functional magnetic resonance imaging studies of WM training using Activation Likelihood Estimation. Our results demonstrate that WM training is associated exclusively with decreases in blood oxygenation level-dependent responses in clusters within the fronto-parietal system that underlie WM, including the bilateral inferior parietal lobule, middle and superior frontal gyri, and medial frontal gyrus bordering on the cingulate gyrus. We discuss the various psychological and physiological mechanisms that could be responsible for the observed reductions in the BOLD signal in relation to WM training, and consider their implications for the construct of WM span as a limited resource.

This book is not a critique of digital ethics but rather a hack. It follows the method of hacking by developing an exploit kit on the basis of state-of-the-art social theory, which it uses to breach the insecure legacy system upon which the discourse of digital ethics is running. This legacy system is made up of four interdependent components: the philosophical mythology of humanism, social science critique, media scandalization, and the activities of many civil society organisations lobbying for various forms (...) of regulation. The hack exposes the bugs, the sloppy programming, and the false promises of current digital ethics, and, because it is an ethical hack, redesigns digital ethics so that it can address the problems of the global network society. The main idea of the book is that the social world of meaning is based on information, which, because of its relational nature, must be understood more as a common good than as private property. A digital ethics that relies upon humanistic individualism cannot address the issues arising from the global network society based upon information. This demands a complete revision of the philosophical foundations of current digital ethics by means of a redesign of ethics as a theory of governance by design. (shrink)

Although A-consciousness and P-consciousness are conceptually distinct, a refined notion of A-consciousness makes it plausible that the two are empirically inseparable. I suggest that the notion of direct availability for global control can play a central role here, and draw out some consequences.

The physician-patient relationship has changed over the last several decades, requiring a systematic reevaluation of the competing demands of patients, physicians, and families. In the era of genetic testing, using a model of patient care known as the family covenant may prove effective in accounting for these demands. The family covenant articulates the roles of the physician, patient, and the family prior to genetic testing, as the participants consensually define them. The initial agreement defines the boundaries of autonomy and benefit (...) for all participating family members. The physician may then serve as a facilitator in the relationship, working with all parties in resolving potential conflicts regarding genetic information. The family covenant promotes a fuller discussion of the competing ethical claims that may come to bear after genetic test results are received. (shrink)

‘‘Undone science’’ refers to areas of research that are left unfunded, incomplete, or generally ignored but that social movements or civil society organizations often identify as worthy of more research. This study mobilizes four recent studies to further elaborate the concept of undone science as it relates to the political construction of research agendas. Using these cases, we develop the argument that undone science is part of a broader politics of knowledge, wherein multiple and competing groups struggle over the construction (...) and implementation of alternative research agendas. Overall, the study demonstrates the analytic potential of the concept of undone science to deepen understanding of the systematic nonproduction of knowledge in the institutional matrix of state, industry, and social movements that is characteristic of recent calls for a ‘‘new political sociology of science.’’.

[This is an edited version of a keynote talk at the conference on Neural Information Processing Systems (NeurIPS) on November 28, 2022, with some minor additions and subtractions.] -/- There has recently been widespread discussion of whether large language models might be sentient or conscious. Should we take this idea seriously? I will break down the strongest reasons for and against. Given mainstream assumptions in the science of consciousness, there are significant obstacles to consciousness in current models: for example, their (...) lack of recurrent processing, a global workspace, and unified agency. At the same time, it is quite possible that these obstacles will be overcome in the next decade or so. I conclude that while it is somewhat unlikely that current large language models are conscious, we should take seriously the possibility that successors to large language models may be conscious in the not-too-distant future.

Against prevailing interpretations, this article contends that Plato's Sophist and Statesman accord the sophist a kind of ‘knowing-how’ (epistêmê). In Soph. 233c10‒d2, the Visitor and Theaetetus agree that the sophist has not truth but a δοξαστικὴ ἐπιστήμη. This phrase cannot mean ‘a seeming knowledge’, for –ικός adjectives formed from verbs express the ability to perform the action denoted by the verb—here, δοξάζω. Although not a first-order, subject-area knowledge, sophistry is a second-order knowledge of how to form and use judgements (doxai). (...) Other acknowledgements of the sophist's epistêmê and the ascription to him of τέχνη, ‘craft/expertise’, confirm that the Visitor's conclusion is not to be dismissed as irony. To critics who argue from the Gorgias and from other works that Plato must consider the Visitor's conclusion an error, the author replies: 1) other dialogues do not control the Visitor dialogues; 2) the Visitor does not validly demonstrate that the sophist lacks all knowledge; 3) by admitting sensibles into Being, the Visitor and Theaetetus allow the objects of epistêmê to include things in the embodied world, even likenesses. Non-philosophers’ epistêmê in the Visitor dialogues is not implicated in the difficulties that critics have raised about epistemology in the so-called Two Worlds dialogues. On this new ontology, even the sophist, if guided by philosophical rulers, can benefit citizens by employing his elenctic expertise as Socrates did, aiding their growth toward virtue. (shrink)

To clarify the notion of computation and its role in cognitive science, we need an account of implementation, the nexus between abstract computations and physical systems. I provide such an account, based on the idea that a physical system implements a computation if the causal structure of the system mirrors the formal structure of the computation. The account is developed for the class of combinatorial-state automata, but is sufficiently general to cover all other discrete computational formalisms. The implementation relation is (...) non-vacuous, so that criticisms by Searle and others fail. This account of computation can be extended to justify the foundational role of computation in artificial intelligence and cognitive science. (shrink)

Taking a social identity approach to health behaviors, this research examines whether experimentally “activating” the human identity is an effective public-health strategy to curb the spread of COVID-19. Three goals of the research include examining: whether the human identity can be situationally activated using an experimental manipulation, whether activating the human identity causally increases behavioral intentions to protect the self and others from COVID-19, and whether activating the human identity causally increases behaviors that help protect vulnerable communities from COVID-19. Across (...) two preregistered experiments, results suggest the manipulation of identification with humanity had a significant but small effect on participants’ psychological bond with all humanity, but not their concern for all humanity. However, the manipulation had no causal effect on health-related behavioral intentions or helping behaviors that reduce the spread of COVID-19. Limitations, future directions, and direct benefits of the research are discussed. (shrink)

This chapter provides a rich philosophical discussion of superintelligence, a widely discussed piece that has encouraged philosophers of mind to take transhumanism, mind uploading, and the singularity more seriously. It starts with the argument for a singularity: is there good reason to believe that there will be an intelligence explosion? Next, the chapter considers how to negotiate the singularity: if it is possible that there will be a singularity, how can we maximize the chances of a good outcome? Finally, it (...) considers the place of humans in a post‐singularity world, with special attention to questions about uploading: can an uploaded human be conscious, and will uploading preserve personal identity? The chapter also analyzes whether there are certain constraints on design of artificial intelligence (AI) and AI+ that we might impose, in order to increase the chances of a good outcome. (shrink)

For some evolutionary psychology is merely a field of inquiry, but for others it is a robust paradigm involving specific theories about the nature and evolution of the human mind. Proponents of this paradigm claim to have made several important discoveries regarding the evolved architecture of the mind. Highly publicized discoveries include a cheater-detection module, a psychological sex difference in jealousy, and motivational mechanisms underlying parental love and its lapses, which purportedly result in child maltreatment. In this article, I argue (...) that the empirical evidence for these ‘discoveries’ is inconclusive, at best. I suggest that, as the reigning paradigm in evolutionary psychology has produced questionable results, the evolutionary study of human psychology is still in need of a guiding paradigm. (shrink)

The search for neural correlates of consciousness (or NCCs) is arguably the cornerstone in the recent resurgence of the science of consciousness. The search poses many difficult empirical problems, but it seems to be tractable in principle, and some ingenious studies in recent years have led to considerable progress. A number of proposals have been put forward concerning the nature and location of neural correlates of consciousness. A few of these include.

Does consciousness collapse the quantum wave function? This idea was taken seriously by John von Neumann and Eugene Wigner but is now widely dismissed. We develop the idea by combining a mathematical theory of consciousness (integrated information theory) with an account of quantum collapse dynamics (continuous spontaneous localization). Simple versions of the theory are falsified by the quantum Zeno effect, but more complex versions remain compatible with empirical evidence. In principle, versions of the theory can be tested by experiments with (...) quantum computers. The upshot is not that consciousness-collapse interpretations are clearly correct, but that there is a research program here worth exploring. (shrink)

For over half a century there have been concerns about increases in the occurrence of academic misconduct by higher education students and this is now claimed to have reached crisis proportions (e.g. Mostrous & Kenber, 2016a ). This study explores the extent to which multi-national faculty judge the effectiveness of higher education institutions in dealing with such misconduct. A survey of multi-national higher education faculty was conducted to explore the perceived barriers to the implementation of academic integrity processes. It asked (...) faculty how likely some hypothetical scenarios of failures of such processes were to occur in the real world of higher education institutions. 63% of our participants perceived there to be institutional and/or faculty barriers to effectively dealing with academic misconduct. Mostly, they blamed the higher education model for this which, in the interests of mass education, has come to prioritise the need for institutions to focus more on their quantity of output as corporate business enterprises than on the integrity of their output as educators. In discussing participants’ comments, about the relationship of faculty to their employing institutions, Schein and Scheins’ ( 2016 ) theory of three levels of organisational culture was used. Participants’ comments suggested that, at the deepest level of organisational culture i.e. basic underlying taken-for-granted assumptions about beliefs and values, inadequate integrity measures have tended to become normalised. Despite the often considerable, efforts of the institutions, organisational barriers were noted which mitigate against faculty behaving professionally i.e. from doing a ‘good job’ in respect of student academic misconduct. Some blame was also placed on faculty. We argue that apparent institutional inability to effectively manage the integrity process, has potentially significant consequences for wider society. We discuss ways in which this situation might be improved including a recommendation that governments regulate this aspect of the corporate social responsibility of higher education institutions as they do other aspects, requiring that it be managed effectively.

More than a decade ago, philosopher John Searle started a long-running controversy with his paper “Minds, Brains, and Programs” (Searle, 1980a), an attack on the ambitious claims of artificial intelligence (AI). With his now famous _Chinese Room_ argument, Searle claimed to show that despite the best efforts of AI researchers, a computer could never recreate such vital properties of human mentality as intentionality, subjectivity, and understanding. The AI research program is based on the underlying assumption that all important aspects of (...) human cognition may in principle be captured in a computational model. This assumption stems from the belief that beyond a certain level, implementational details are irrelevant to cognition. According to this belief, neurons, and biological wetware in general, have no preferred status as the substrate for a mind. As it happens, the best examples of minds we have at present have arisen from a carbon-based substrate, but this is due to constraints of evolution and possibly historical accidents, rather than to an absolute metaphysical necessity. As a result of this belief, many cognitive scientists have chosen to focus not on the biological substrate of the mind, but instead on the abstract causal structure_ _that the mind embodies (at an appropriate level of abstraction). The view that it is abstract causal structure that is essential to mentality has been an implicit assumption of the AI research program since Turing (1950), but was first articulated explicitly, in various forms, by Putnam (1960), Armstrong (1970) and Lewis (1970), and has become known as _functionalism_. From here, it is a very short step to _computationalism_, the view that computational structure is what is important in capturing the essence of mentality. This step follows from a belief that any abstract causal structure can be captured computationally: a belief made plausible by the Church–Turing Thesis, which articulates the power. (shrink)

Hypothesized relationships among reports by employees of moral distress, their perceptions of their manager’s behavioral integrity (BI), and employee reports of job satisfaction, stress, job engagement, turnover likelihood, absenteeism, work-to-family conflict, health, and life satisfaction were tested using data from the 2008 National Study of the Changing Workforce (n = 2,679). BI was positively related to job satisfaction, job engagement, health, and life satisfaction and negatively to stress, turnover likelihood, and work-to-family conflict, while moral distress was inversely related to those (...) outcomes. The magnitudes of relationships with job satisfaction, job engagement, and life satisfaction were greater with BI than with moral distress. Moral distress mediated the relationships between BI and the employee outcomes, supporting the view that employee’s perceptions of their manager’s BI might influence the employee’s behaviors as well as their attitudes.

In response to a recent argument by David Bloor, I argue that denying absolutes does not necessarily lead to relativism, that one can be a fallibilist without being a relativist. At issue are the empirical natural sciences and what might be called “framework relativism”, that is, the idea that there is always a conceptual scheme or set of practices in use, and all observations are theory-laden relative to the framework. My strategy is to look at the elements that define (...) a relativist stance and show where the pragmatic fallibilist disagrees. Defending the pragmatic notion of experience will be central, given that relativists reject the idea that experience can play a role in objectively justifying belief. We can reject all absolutes and start from the premise that everything is historical, contingent, and situated. One of the lessons of pragmatism is that universal and fixed principles are not necessary for objective knowledge. (shrink)

There is a long tradition in philosophy of using a priori methods to draw conclusions about what is possible and what is necessary, and often in turn to draw conclusions about matters of substantive metaphysics. Arguments like this typically have three steps: first an epistemic claim , from there to a modal claim , and from there to a metaphysical claim.

We prove various results connected together by the common thread of computability theory.First, we investigate a new notion of algorithmic dimension, the inescapable dimension, which lies between the effective Hausdorff and packing dimensions. We also study its generalizations, obtaining an embedding of the Turing degrees into notions of dimension.We then investigate a new notion of computability theoretic immunity that arose in the course of the previous study, that of a set of natural numbers with no co-enumerable subsets. We demonstrate how (...) this notion of $\Pi ^0_1$ -immunity is connected to other immunity notions, and construct $\Pi ^0_1$ -immune reals throughout the high/low and Ershov hierarchies. We also study those degrees that cannot compute or cannot co-enumerate a $\Pi ^0_1$ -immune set.Finally, we discuss a recently discovered truth-table reduction for transforming a Kolmogorov–Loveland random input into a Martin-Löf random output by exploiting the fact that at least one half of such a KL-random is itself ML-random. We show that there is no better algorithm relying on this fact, in the sense that there is no positive, linear, or bounded truth-table reduction which does this. We also generalize these results to the problem of outputting randomness from infinitely many inputs, only some of which are random.Abstract prepared by David J.

Doctors’ strikes are legally permissible in the UK, with the situation differing in other countries. But are they morally permissible? Doug McConnell and Darren Mann have systematically attempted to dismiss the arguments for the moral impermissibility of doctors’ strikes and creatively attempted to provide further moral justification for them. Unfortunately for striking doctors, they fail to achieve this. Meanwhile, junior doctors’ strikes have continued in the UK through 2023 and have now extended into 2024. In this response, which focuses on (...) the UK situation and specifically junior doctors’ strikes in the National Health Service (NHS) in England, I will demonstrate a central problem with their arguments—namely that they underplay the harms caused by prolonged doctors’ strikes by ignoring the harms to patients with cancer. This weakens their conclusion that strikes are morally permissible in terms of the conditions and thresholds they set. I then provide a psychological critique of their justification for strikes in terms of the interests of the public. It follows that invoking the controversial concept of supererogatory action is ungrounded but also absurd when you consider time-critical cancer care. If those representing striking doctors wish to maintain a modicum of moral respectability, they should mitigate for patients with cancer and negotiate reasonably and with urgency. (shrink)

I trace the development of arguments for the consistency of non-Euclidean geometries and for the independence of the parallel postulate, showing how the arguments become more rigorous as a formal conception of geometry is introduced. I analyze the kinds of arguments offered by Jules Hoüel in 1860-1870 for the unprovability of the parallel postulate and for the existence of non-Euclidean geometries, especially his reaction to the publication of Beltrami’s seminal papers, showing that Beltrami was much more concerned with the existence (...) of non-Euclidean objects than he was with the formal consistency of non-Euclidean geometries. The final step towards rigorous consistency proofs is taken in the 1880s by Henri Poincaré. It is the formal conception of geometry, stripping the geometric primitive terms of their usual meanings, that allows the introduction of a modern fully rigorous consistency proof. (shrink)
