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.

The fact that the names of biological species refer independently of identifying descriptions does not support the view of Ghiselin and Hull that species are individuals. Species may be regarded as natural kinds whose members share an essence which distinguishes them from the members of other species and accounts for the fact that they are reproductively isolated from the members of other species. Because evolutionary theory requires that species be spatiotemporally localized their names cannot occur in scientific laws. If natural (...) kind status is denied to species on this ground, it must also be denied to most classes of concrete entities which are now accorded such status. (shrink)

Sensory substitution devices (SSDs) aim to compensate for the loss of a sensory modality, typically vision, by converting information from the lost modality into stimuli in a remaining modality. “The vOICe” is a visual-to-auditory SSD which encodes images taken by a camera worn by the user into “soundscapes” such that experienced users can extract information about their surroundings. Here we investigated how much detail was resolvable during the early induction stages by testing the acuity of blindfolded sighted, naïve vOICe users. (...) Initial performance was well above chance. Participants who took the test twice as a form of minimal training showed a marked improvement on the second test. Acuity was slightly but not significantly impaired when participants wore a camera and judged letter orientations “live”. A positive correlation was found between participants' musical training and their acuity. The relationship between auditory expertise via musical training and the lack of a relationship with visual imagery, suggests that early use of a SSD draws primarily on the mechanisms of the sensory modality being used rather than the one being substituted. If vision is lost, audition represents the sensory channel of highest bandwidth of those remaining. The level of acuity found here, and the fact it was achieved with very little experience in sensory substitution by naïve users is promising. (shrink)

An important function of the self is to identify external objects that are potentially personally relevant. We suggest that such objects may be identified through mere ownership. Extant research suggests that encoding information in a self-relevant context enhances memory , thus an experiment was designed to test the impact of ownership on memory performance. Participants either moved or observed the movement of picture cards into two baskets; one of which belonged to self and one which belonged to another participant. A (...) subsequent recognition test revealed that there was a significant memory advantage for objects that were owned by self. Acting on items had no impact on memory. Results are discussed with reference to the importance of self-object associations in cognition. (shrink)

It is often argued that human emotions, and the cognitions that accompany them, involve refinements of, and extensions to, more basic functionality shared with other species. Such refinements may rely on common or on distinct processes and representations. Multi-level theories of cognition and affect make distinctions between qualitatively different types of representations often dealing with bodily, affective and cognitive attributes of self-related meanings. This paper will adopt a particular multi-level perspective on mental architecture and show how a mechanism of subsystem (...) differentiation could have allowed an evolutionarily “old” role for emotion in the control of action to have altered into one more closely coupled to meaning systems. We conclude by outlining some illustrative consequences of our analysis that might usefully be addressed in research in comparative psychology, cognitive archaeology, and in laboratory research on memory for emotional material.

Metabolic Syndrome is a cluster of risk factors (including obesity, hypertension and insulin resistance), which is associated with late‐onset diabetes and coronary heart disease. Elevated levels of the protease inhibitor PAI‐1 are well‐known molecular markers of the Metabolic Syndrome. Here, however, we present a hypothesis that PAI‐1 acts as a causative factor in the development of Metabolic Syndrome and its clinical sequelae. We propose that PAI‐1 inhibits the activity of members of the proprotein convertase (PC) class of serine proteases and (...) that this underlies, at a molecular level, many of the other features of the Metabolic Syndrome cluster.

Emotion regulation strategies may reduce the negative relationship between math anxiety and mathematics accuracy, but different strategies may differ in their effectiveness. We recorded electrodermal activity to examine the effect of physiological arousal on performance during different applied ER strategies. We explored how ER strategies might affect the decreases in accuracy attributed to physiological arousal in high math anxious individuals. Participants were instructed to use cognitive reappraisal, expressive suppression, or a “business as usual” strategy. During the ES condition, HMA individuals (...) showed decreases in math accuracy associated with increased EDA, compared to low math anxious individuals. For both HMA and LMA groups, CR reduced the association between physiological arousal and math accuracy, such that even elevated physiological arousal levels no longer had a negative association with math accuracy. These results show that CR provides a promising technique for ameliorating the negative relationship between math anxiety and math accuracy. (shrink)

Grounded procedures of separation are conceptualized as a learned concept. The simultaneous cultural universality of the general idea and immense diversity of its implementations might be better understood through the lens of dual inheritance theories. By drawing on examples from developmental psychology and emotion theorizing, we argue that an innate blueprint might underlie learned implementations of cleansing that vary widely.

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)

The book is an extended study of the problem of consciousness. After setting up the problem, I argue that reductive explanation of consciousness is impossible , and that if one takes consciousness seriously, one has to go beyond a strict materialist framework. In the second half of the book, I move toward a positive theory of consciousness with fundamental laws linking the physical and the experiential in a systematic way. Finally, I use the ideas and arguments developed earlier to defend (...) a form of strong artificial intelligence and to analyze some problems in the foundations of quantum mechanics. (shrink)

[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.

SummarySubjecting to a detailed analysis Kant's diagnosis of dialectical error in the Transcendental Dialectic of the first Critique, the author posits that Kant's understanding of such error is, to the extent that it conflates the subjective‐objective, phenomenal‐noumenal, and regulative‐constitutive distinctions, fundamentally incoherent. The author argues not only that these three distinctions cannot on Kant's own terms be conflated, but also that Kant's treatment of dialectical error is further vitiated by circularity of argument: Kant proposes to explain the three distinctions by (...) means of the notion of transcendental error, which however the distinctions themselves were supposed to explain in the first place. After showing that Kant's diagnosis of dialectical error cannot be salvaged even by resorting to the Kantian concept of “transcendental subreption”, the author concludes that unless Kant could in some other way spell out the minimal conditions for dialectical error, Kant's very distinction between understanding and reason becomes difficult to justify.

Abstract: A 1991 article by psychologist John D. Carter offers an underdeveloped insight that typologies for relating science and religion might be fruitfully formulated in discipline-specific perspectives. This essay thus covers a specifically theological perspective only briefly outlined in Carter, and it expands four models that theologians have used to relate religion and science. This essay renames these models and expands their implications, especially for addressing the behavioral sciences. (1) The contrarian model generally opposes science, (2) the apologetic makes theology (...) congenial to science, (3) the correlational holds both disciplines in tension, and (4) the synthetic attempts a grand unification of them. Arguing from the theologian's perspective, this essay is intended to demonstrate that different models/methods for relating science and religion are really reflections of deeper religious attitudes and argues that the task for which a method is employed ultimately determines its adequacy within that attitude's constraints.

In 2018, William Lane Craig and Erik J. Wielenberg participated in a debate at North Carolina State University, addressing the question: "God and Morality: What is the best account of objective moral values and duties?" Craig argued that theism provides a sound foundation for objective morality whereas atheism does not. Wielenberg countered that morality can be objective even if there is no God. This book includes the full debate, as well as endnotes with extended discussions that were not included in (...) the debate. It also includes five chapters by other philosophers who have written substantive responses to the debate - J. P. Moreland, David Baggett, Mark Linville, Wes Morriston, and Michael Huemer. The book provides crucial resources for better understanding moral realism and its dependence on, or independence from, theistic foundations. Key Features A valuable debate about whether or not God is the best explanation for objective morality, bringing together theists and atheists working on the same subject who normally are not in conversation with each other. Includes clear coverage of ontological and epistemological issues in metaethical theories, focusing on Divine Command Theory and Non-natural Robust Moral Realism. Engaging and accessible throughout, making the book well suited for undergraduate and seminary classrooms. (shrink)

There has been considerable recent interest in the “collective moral autonomy” thesis (CMA), that is, the notion that we can predicate moral successes, failures, and duties of collectives even if there are no comparable successes, failures, and duties among members. One reason why this position looks appealing is because the opposing individualist position seems to have what we might call an accounting problem. Individualists maintain that only individuals can be subjects of moral success, failure, or duty; however, many reasonable judgments (...) about collective actions include moral information on a scale and of a stringency that it does not seem possible to predicate even of the duties of members who have steering power in the actions of the collective. Here I offer a paradigm for thinking about responsibility judgments in organized collective cases to help individualism solve its accounting problem, and allow us to account within a strict individualist perspective for moral information that ostensibly favors CMA.

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)

I argue that virtual reality is a sort of genuine reality. In particular, I argue for virtual digitalism, on which virtual objects are real digital objects, and against virtual fictionalism, on which virtual objects are fictional objects. I also argue that perception in virtual reality need not be illusory, and that life in virtual worlds can have roughly the same sort of value as life in non-virtual worlds.

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.

In this book, David Stump traces alternative conceptions of the a priori in the philosophy of science and defends a unique position in the current debates over conceptual change and the constitutive elements in science. Stump emphasizes the unique epistemological status of the constitutive elements of scientific theories, constitutive elements being the necessary preconditions that must be assumed in order to conduct a particular scientific inquiry. These constitutive elements, such as logic, mathematics, and even some fundamental laws of nature, (...) were once taken to be a priori knowledge but can change, thus leading to a dynamic or relative a priori. Stump critically examines developments in thinking about constitutive elements in science as a priori knowledge, from Kant’s fixed and absolute a priori to Quine’s holistic empiricism. By examining the relationship between conceptual change and the epistemological status of constitutive elements in science, Stump puts forward an argument that scientific revolutions can be explained and relativism can be avoided without resorting to universals or absolutes.

Dilthey’s moral writings have received scant attention over the years, perhaps due to his apparent tendency toward relativism. This essay offers a unified look at Dilthey’s moral writings in the context of his Kantian-styled “Critique of Historical Reason.” I present the Dilthey of the moral writings as an observer of reason in the spirit of Kant, watching practical reason devolve into error when it applies itself beyond the bounds of possible experience. Drawing on moral writings from across Dilthey’s corpus, I (...) retrace Dilthey’s argument that moral theories from Kantianism and utilitarianism to natural law theory suffer significant motivational problems because of the way they transcend the “synthesis” of moral perception. Dilthey’s argument suggests that abstract moral theory is always bound to seem unmotivating and unreal from the standpoint of lived experience, and perhaps that, to avoid this, moral philosophy should confine itself to more situated, case-specific judgments.

Is conceptual analysis required for reductive explanation? If there is no a priori entailment from microphysical truths to phenomenal truths, does reductive explanation of the phenomenal fail? We say yes . Ned Block and Robert Stalnaker say no.

The philosophical interest of verbal disputes is twofold. First, they play a key role in philosophical method. Many philosophical disagreements are at least partly verbal, and almost every philosophical dispute has been diagnosed as verbal at some point. Here we can see the diagnosis of verbal disputes as a tool for philosophical progress. Second, they are interesting as a subject matter for first-order philosophy. Reflection on the existence and nature of verbal disputes can reveal something about the nature of concepts, (...) language, and meaning. In this article I first characterize verbal disputes, spell out a method for isolating and resolving them, and draw out conclusions for philosophical methodology. I then use the framework to draw out consequences in first-order philosophy. In particular, I argue that the analysis of verbal disputes can be used to support the existence of a distinctive sort of primitive concept and that it can be used to reconstruct a version of an analytic/synthetic distinction, where both are characterized in dialectical terms alone.

David J. Kalupahana's Buddhist Philosophy: A Historical Analysis has, since its original publication in 1976, offered an unequaled introduction to the philosophical principles and historical development of Buddhism. Now, representing the culmination of Dr. Kalupahana's thirty years of scholarly research and reflection, A History of Buddhist Philosophy builds upon and surpasses that earlier work, providing a completely reconstructed, detailed analysis of both early and later Buddhism.

This chapter analyzes aspects of the relationship between consciousness and intentionality. It focuses on the phenomenal character and the intentional content of perceptual states, canvassing various possible relations among them. It argues that there is a good case for a sort of representationalism, although this may not take the form that its advocates often suggest. By mapping out some of the landscape, the chapter tries to open up territory for different and promising forms of representationalism to be explored in the (...) future. In particular, it argues for a nonreductive, narrow, and Fregean variety of representationalism, which contrasts strongly with more widely explored varieties. It concludes with some words about the fundamental relationship between consciousness and intentionality. (shrink)

Cartesian arguments for global skepticism about the external world start from the premise that we cannot know that we are not in a Cartesian scenario such as an evil-demon scenario, and infer that because most of our empirical beliefs are false in such a scenario, these beliefs do not constitute knowledge. Veridicalist responses to global skepticism respond that arguments fail because in Cartesian scenarios, many or most of our empirical beliefs are true. Some veridicalist responses have been motivated using verificationism, (...) externalism, and coherentism. I argue that a more powerful veridicalist response to global skepticism can be motivated by structuralism, on which physical entities are understood as those that play a certain structural role. I develop the structuralist response and address objections. (shrink)

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..

One of the enduring concerns of moral philosophy is deciding who or what is deserving of ethical consideration. Much recent attention has been devoted to the "animal question" -- consideration of the moral status of nonhuman animals. In this book, David Gunkel takes up the "machine question": whether and to what extent intelligent and autonomous machines of our own making can be considered to have legitimate moral responsibilities and any legitimate claim to moral consideration. The machine question poses a (...) fundamental challenge to moral thinking, questioning the traditional philosophical conceptualization of technology as a tool or instrument to be used by human agents. Gunkel begins by addressing the question of machine moral agency: whether a machine might be considered a legitimate moral agent that could be held responsible for decisions and actions. He then approaches the machine question from the other side, considering whether a machine might be a moral patient due legitimate moral consideration. Finally, Gunkel considers some recent innovations in moral philosophy and critical theory that complicate the machine question, deconstructing the binary agent--patient opposition itself. Technological advances may prompt us to wonder if the science fiction of computers and robots whose actions affect their human companions could become science fact. Gunkel's argument promises to influence future considerations of ethics, ourselves, and the other entities who inhabit this world. (shrink)
