We propose that, for the purpose of studying theoretical properties of the knowledge of an agent with Artificial General Intelligence (that is, the knowledge of an AGI), a pragmatic way to define such an agent’s knowledge (restricted to the language of Epistemic Arithmetic, or EA) is as follows. We declare an AGI to know an EA-statement φ if and only if that AGI would include φ in the resulting enumeration if that AGI were commanded: “Enumerate all the EA-sentences which you (...) know.” This definition is non-circular because an AGI, being capable of practical English communication, is capable of understanding the everyday English word “know” independently of how any philosopher formally defines knowledge; we elaborate further on the non-circularity of this circular-looking definition. This elegantly solves the problem that different AGIs may have different internal knowledge definitions and yet we want to study knowledge of AGIs in general, without having to study different AGIs separately just because they have separate internal knowledge definitions. Finally, we suggest how this definition of AGI knowledge can be used as a bridge which could allow the AGI research community to import certain abstract results about mechanical knowing agents from mathematical logic.

Missing from Quartz & Sejnowski's (Q&S's) unique and valuable effort to relate cognitive development to neural constructivism is an examination of the global emergent properties of adding new neural circuits. Such emergent properties can be studied with computational models. Modeling with generative connectionist networks shows that synaptogenic mechanisms can account for progressive increases in children's representational power.

Bridging the gap between the world of science and the realm of the spiritual, B. Alan Wallace introduces a natural theory of human consciousness that has its roots in contemporary physics and Buddhism. Wallace's "special theory of ontological relativity" suggests that mental phenomena are _conditioned_ by the brain, but do not _emerge_ from it. Rather, the entire natural world of mind and matter, subjects and objects, arises from a unitary dimension of reality that is more fundamental than these dualities, as (...) proposed by Wolfgang Pauli and Carl Jung. To test his hypothesis, Wallace employs the Buddhist meditative practice of _samatha_, refining one's attention and metacognition, to create a kind of telescope to examine the space of the mind. Drawing on the work of the physicist John Wheeler, he then proposes a more general theory in which the participatory nature of reality is envisioned as a self-excited circuit. In comparing these ideas to the Buddhist theory known as the Middle Way philosophy, Wallace explores further aspects of his "general theory of ontological relativity," which can be investigated by means of _vipasyana_, or insight, meditation. Wallace then focuses on the theme of symmetry in reference to quantum cosmology and the "problem of frozen time," relating these issues to the theory and practices of the Great Perfection school of Tibetan Buddhism. He concludes with a discussion of the general theme of complementarity as it relates to science and religion. The theories of relativity and quantum mechanics were major achievements in the physical sciences, and the theory of evolution has had an equally deep impact on the life sciences. However, rigorous scientific methods do not yet exist to observe mental phenomena, and naturalism has its limits for shedding light on the workings of the mind. A pioneer of modern consciousness research, Wallace offers a practical and revolutionary method for exploring the mind that combines the keenest insights of contemporary physicists and philosophers with the time-honored meditative traditions of Buddhism.

As bridges or brains become bigger or smaller, the changes pose problems of design thatneed to be solved. Larger brains could have larger or more neurons, or both. With largerneurons, it becomes difficult to maintain conduction times over longer axons andelectrical cable properties over longer dendrites. With more neurons, it becomes difficultfor each neuron to maintain its proportion of connections with other neurons. Theseproblems are addressed by making brains more modular, thereby reducing the lengths ofmany connections, and by altering functions. (...) Smaller brains may not have enoughneurons for all circuits, and they may lose modules and functions. Mammals with moreneocortex tend to have more cortical areas and more columns and types of columnswithin the larger areas. (shrink)

The fault ride-through capability and fault current issues are the main challenges in doubly fed induction generator- based wind turbines. Application of the bridge-type fault current limiter was recognized as a promising solution to cope with these challenges. This paper proposes a nonlinear sliding mode controller for the BFCL to enhance the FRT performance of the DFIG-based WT. This controller has robust performance in unpredicted voltage sag level and nonlinear features. Theoretical discussions, power circuit, and nonlinear control consideration of (...) the SMC-based BFCL are conducted, and then, its performance is verified through time-domain simulations in the PSCAD/EMTDC environment. To reduce the chattering phenomenon and decrease the reaching time, it used the exponential reaching law for designed SMC. Also, the SMC-based BFCL performance is compared with the conventional and PI controller-based BFCL for both symmetrical and asymmetrical short-circuit faults. Simulation results reveal that the SMC-based BFCL provides better performance compared with the conventional and PI controller-based BFCL to enhance the FRT. (shrink)

Intermediate constructs are required as bridges between complex behaviors and realistic models of neural circuitry. For cognitive scientists in general, schemas are the appropriate functional units; brain theorists can work with neural layers as units intermediate between structures subserving schemas and small neural circuits.After an account of different levels of analysis, we describe visuomotor coordination in terms of perceptual schemas and motor schemas. The interest of schemas to cognitive science in general is illustrated with the example of perceptual schemas (...) in high-level vision and motor schemas in the control of dextrous hands.Rana computatrix, the computational frog, is introduced to show how one constructs an evolving set of model families to mediate flexible cooperation between theory and experiment. Rana computatrix may be able to do for the study of the organizational principles of neural circuitry what Aplysia has done for the study of subcellular mechanisms of learning. Approach, avoidance, and detour behavior in frogs and toads are analyzed in terms of interacting schemas. Facilitation and prey recognition are implemented as tectal-pretectal interactions, with the tectum modeled by an array of tectal columns. We show how layered neural computation enters into models of stereopsis and how depth schemas may involve the interaction of accommodation and binocular cues in anurans. (shrink)

Where much contemporary philosophy seeks to stave off the "threat" of nihilism by safeguarding the experience of meaning--characterized as the defining feature of human existence--from the Enlightenment logic of disenchantment, this book attempts to push nihilism to its ultimate conclusion by forging a link between revisionary naturalism in Anglo-American philosophy and anti-phenomenological realism in recent French philosophy. Contrary to an emerging "post-analytic" consensus which would bridge the analytic-continental divide by uniting Heidegger and Wittgenstein against the twin perils of scientism (...) and skepticism, this book short-circuits both traditions by plugging eliminative materialism directly into speculative realism.

In lieu of an abstract, here is a brief excerpt of the content:The Fool’s Truth: Diderot, Goethe, and HegelJames SchmidtI. Of the many works that crossed from France into Germany during the “long” eighteenth century, none took as circuitous a route as Rameau’s Nephew. Begun by Diderot in 1761 but never published during his lifetime, the dialogue was among the works sent to Catherine the Great after his death in 1784. A copy of the manuscript was brought to Jena late (...) in 1804, where it was read by Schiller and passed on to Goethe, who immediately set about translating it into German. Goethe’s translation was published in the Spring of 1805 but, as Goethe later complained, made little impact on the German reading public. 1 There was, however, one notable exception: Georg Wilhelm Friedrich Hegel.Hegel’s interpretation of Diderot’s dialogue in his 1807 Phenomenology of Spirit has long been an topic of considerable interest. Marxists—and, for that matter, Marx himself—have regarded the Phenomenology’s discussion of Diderot as illustrative of Hegel’s interest in the social and economic foundations of modern society. 2 For Lionel Trilling, it marked an important step in the genesis of the modern ideal of “authenticity.” 3 More recently, the tensions between Diderot’s “dialogizing” of the Enlightenment and the [End Page 625] Hegelian dialectic have been explored by a number of commentators. 4 Less attention, however, has been paid to the fact that the words Hegel appropriated were not, strictly speaking, Diderot’s, but rather came from Goethe’s translation. 5 Before Rameau’s Nephew could appear in the pages of Hegel’s Phenomenology, it first passed into German in a translation that, no less than Hegel, inserted the text into a rather different context from the one in which it had originated.A consideration of Hegel’s appropriation of Rameau’s Nephew thus involves us in questions about the transporting, translating, and transposing of works across borders, languages, and genres. I will begin by examining briefly how Goethe went about presenting an eighteenth century French text to a nineteenth-century German audience. I will then explore, at greater length, how Hegel went about situating this most peculiar of dialogues into his most baffling of books. Finally, I will reflect on some of the tensions between what Diderot wrote and what Hegel attempted to do with it.II. “Now, think of a city like Paris,” Goethe told Eckermann, bemoaning the “isolated, miserable sort of life” to which German intellectuals had been condemned. In Paris one could find “all of the leading minds of a great kingdom all together at the same spot, mutually instructing and advancing one another through daily contact, conflict, and rivalry.” The leading German intellectuals, in contrast, were scattered about: “There is one in Vienna, another in Berlin, another in Königsberg, another in Bonn or Düsseldorf, all fifty to a hundred miles away from each other, so that personal contact and personal exchange of ideas count as rare events.” In Paris “the best from the realms of nature and art from throughout the world lies open for daily inspection,” while “every passage over a bridge or a square recalls a mighty past” and “every street corner has evolved into a piece of history.” It was a city where “men such as Molière, Voltaire, Diderot, and the like have kept up a current of intellect such as has not been found in a single spot anywhere else in the entire world.” 6 Weimar, quite clearly, was not Paris.Rameau’s Nephew was so thoroughly a creature of Paris that the mere thought of rendering it into German might have dismayed a weaker soul than Goethe. Moi and Lui begin a conversation at the Café de la Régence that will [End Page 626] lead them from discussions of the contest between French and Italian styles in music to a consideration of the prospects for human autonomy. In between they will pass over such matters as the social utility of geniuses, the tension between aesthetics and morality, the proper upbringing of children, and the structure of social dependency, pausing from time to time as Lui loses himself in increasingly wilder pantomimes.

The visuospatial system integrates inner and outer functional processes, organizing spatial, temporal, and social interactions between the brain, body, and environment. These processes involve sensorimotor networks like the eye–hand circuit, which is especially important to primates, given their reliance on vision and touch as primary sensory modalities and the use of the hands in social and environmental interactions. At the same time, visuospatial cognition is intimately connected with memory, self-awareness, and simulation capacity. In the present article, we review issues associated (...) with investigating visuospatial integration in extinct human groups through the use of anatomical and behavioral data gleaned from the paleontological and archaeological records. In modern humans, paleoneurological analyses have demonstrated noticeable and unique morphological changes in the parietal cortex, a region crucial to visuospatial management. Archaeological data provides information on hand–tool interaction, the spatial behavior of past populations, and their interaction with the environment. Visuospatial integration may represent a critical bridge between extended cognition, self-awareness, and social perception. As such, visuospatial functions are relevant to the hypothesis that human evolution is characterized by changes in brain–body–environment interactions and relations, which enhance integration between internal and external cognitive components through neural plasticity and the development of a specialized embodiment capacity. We therefore advocate the investigation of visuospatial functions in past populations through the paleoneurological study of anatomical elements and archaeological analysis of visuospatial behaviors.

The neural networks that constitute corticostriatothalamocortical circuits between prefrontal cortex and subcortical structure provide a heuristic framework for bridging gaps between neurocircuitry and executive dysfunction in attention deficit hyperactivity disorder (ADHD). “Cool” and “Hot” executive functional theory and the models of dual pathway are supposed to be applied within the neuropsychology of ADHD. The theoretical model elaborated response inhibition and delayed gratification in ADHD. We aimed to review and summarize the literature about the circuits on ADHD and ADHD-related (...) comorbidities, as well as the effects of neurocircuitry on the executive dysfunction in ADHD.

The mind-body problem arises because all theories about mind-brain connections are too deeply obscure to gain general acceptance. This essay suggests a clear, simple, mind-brain solution that avoids all these perennial obscurities. (1) It does so, first of all, by reworking Strawson and Stoljar’s views. They argue that while minds differ from observable brains, minds can still be what brains are physically like behind the appearances created by our outer senses. This could avoid many obscurities. But to clearly do so, (...) it must first clear up its own deep obscurity about what brains are like behind appearances, and how they create the mind’s privacy, unity and qualia – all of which observable brains lack. (2) This can ultimately be done with a clear, simple assumption: our consciousness is the physical substance that certain brain events consist of beyond appearances. For example, the distinctive electrochemistry in nociceptor ion channels wholly consists of pain. This rejects that pain is a brain property: instead it’s a brain substance that occupies space in brains, and exerts forces by which it’s indirectly detectable via EEGs. (3) This assumption is justified because treating pains as physical substances avoids the perennial obscurities in mind-body theories. For example, this ‘clear physicalism’ avoids the obscure nonphysical pain of dualism and its spinoffs. Pain is instead an electrochemical substance. It isn’t private because it’s hidden in nonphysical minds, but instead because it’s just indirectly detected in the physical world in ways that leave its real nature hidden. (4) Clear physicalism also avoids puzzling reductions of private pains into more fundamental terms of observable brain activity. Instead pain is a hidden, private substance underlying this observable activity. Also, pain is fundamental in itself, for it’s what some brain activity fundamentally consists of. This also avoids reductive idealist claims that the world just exists in the mind. They yield obscure views on why we see a world that isn’t really out there. (5) Clear physicalism also avoids obscure claims that pain is information processing which is realizable in multiple hardwares (not just in electrochemistry). Molecular neuroscience now casts doubt on multiple realization. Also, it’s puzzling how abstract information gets ‘realized’ in brains and affects brains (compare ancient quandries on how universals get embodied in matter). A related idea is that of supervenient properties in nonreductive physicalism. They involve obscure overdetermination and emergent consciousness. Clear physicalism avoids all this. Pain isn’t an abstract property obscurely related to brains – it’s simply a substance in brains. (6) Clear physicalism also avoids problems in neuroscience. Neuroscience explains the mind’s unity in problematic ways using synchrony, attention, etc.. Clear physicalism explains unity in terms of intense neuroelectrical activity reaching continually along brain circuits as a conscious whole. This fits evidence that just highly active, highly connected circuits are fully conscious. Neuroscience also has problems explaining how qualia are actually encoded by brains, and how to get from these abstract codes to actual pain, fear, etc.. Clear physicalism explains qualia electrochemically, using growing evidence that both sensory and emotional qualia correlate with very specific electrical channels in neural receptors. Multiple-realization advocates overlook this important evidence. (7) Clear physicalism thus bridges the mind-brain gulf by showing how brains can possess the mind’s qualia, unity and privacy – and how minds can possess features of brain activity like occupying space and exerting forces. This unorthodox nonreductive physicalism may be where physicalism leads to when stripped of all its reductive and nonreductive obscurities. It offers a clear, simple mind-body solution by just filling in what neuroscience is silent about, namely, what brain matter is like behind perceptions of it. (shrink)

In its forty years of existence, Artificial Intelligence has suffered both from the exaggerated claims of those who saw it as the definitive solution of an ancestral dream — that of constructing an intelligent machine-and from its detractors, who described it as the latest fad worthy of quacks. Yet AI is still alive, well and blossoming, and has left a legacy of tools and applications almost unequalled by any other field-probably because, as the heir of Renaissance thought, it represents a (...) possible bridge between the humanities and the natural sciences, philosophy and neurophysiology, psychology and integrated circuits-including systems that today are taken for granted, such as the computer interface with mouse pointer and windows. This writing describes a few results of AI that have modified the scientific world, as well as the way a layman sees computers: thetechnology of programming languages, such asLISP-witness the unique excellence of academic departments that have contributed to them-thecomputing workstations-of which our modern PC is but a vulgarised descendant-theapplications to the educational field-e.g., the realisation of some ideas of genetic epistemology-and tointerdisciplinary philosophy-such as Hofstadter's associations between the arts and mathematics-and the use ofAI techniques in music and musicology. All this has led to a generalisation of AI towards Negrotti's overallTheory of the Artificial, which encompasses further specialisation such asartificial reality, artificial life, and applications ofneural networks among others.

Imagine a world where machines can see and understand the world the way humans do. Rapid progress in artificial intelligence has led to smartphones that recognize faces, cars that detect pedestrians, and algorithms that suggest diagnoses from clinical images, among many other applications. The success of computer vision is founded on a deep understanding of the neural circuits in the brain responsible for visual processing. This book introduces the neuroscientific study of neuronal computations in visual cortex alongside of the (...) psychological understanding of visual cognition and the burgeoning field of biologically-inspired artificial intelligence. Topics include the neurophysiological investigation of visual cortex, visual illusions, visual disorders, deep convolutional neural networks, machine learning, and generative adversarial networks among others. It is an ideal resource for students and researchers looking to build bridges across different approaches to studying and developing visual systems. (shrink)

This volume contains twenty-one selected articles and lectures written by the author over a period of some two decades. The remarkable range of McCulloch's abilities and interests is attested to by the diverse character of the contents, which range from neurophysiology to poetry and a scathing attack on Freud and psychoanalysis. Despite the dazzling diversity of topics treated, there is a readily discernible theme underlying all of McCulloch's work. It is represented explicitly in such papers as the classic "A Logical (...) Calculus of the Ideas Immanent in Nervous Activity," a progenitor of more recent automata studies, and "Why the Mind is in the Head," McCulloch's contribution to the Hixon Symposium. This theme is, in the author's words, "the attempt to found a physiological theory of knowledge" or "experimental epistemology." Philosophers who take identity solutions to the mind-body problem seriously will applaud McCulloch's ingenious and sustained efforts to bridge the gap between conceptual analysis of mental concepts and painstaking scientific investigation of the physical "embodiments" of mental processes. Nevertheless, many philosophers will also be irritated by the way in which McCulloch tends to use mentalistic concepts. When nerve impulses are treated as atomic propositions and thinking is unhesitatingly attributed to a reverberating neural circuit, one cannot help but feel that genuine philosophical issues are in serious danger of being obscured rather than illumined.—V.

The neurosciences are generating new findings regarding genetic and neurobiological aspects of the pathophysiology of mental disorders. Especially, certain genetic risk factors like neuregulin-1 seem to predispose individuals to a psychotic phenotype beyond the limits of traditional classificatory boundaries between organic psychoses in Alzheimer’s disease, bipolar affective disorder and schizophrenia. Little, however, is known about how such genetic risk factors actually confer an increased risk for psychosis in an individual patient. A gap between neuroscientific findings and psychopathological phenomena exists. The (...) main hypothesis how this gap may be bridged is that mental disorders arise as a consequence of dysfunctions of normal mental functions. Modularity may provide a useful conceptual framework in that temporally and/or spatially stable neural circuits subserve certain physiological functions of the human brain, which become the target of pathophysiological effectors. The idea of a modular construction of the human brain is based on neurobiological evidence regarding the columnar architecture of the cerebral cortex, which provides certain elementary analytical functions. Modular dysfunctions may be assessed with methods of experimental psychopathology, in which subsystems of brain functions are tested with standardized experimental psychological techniques (functional psychopathology). The main questions here are how to define a module, and whether the classical neuroscientific definitions can be used to characterize higher integrative functions of the human brain. (shrink)

In this chapter, which has evolved over the last ten years to what I hope will be its perfect Platonic form, I shall first discuss those features of constructive mathematics that distinguish it from its traditional, or classical, counterpart, and then illustrate the practice of that distinction in aspects of complex analysis whose classical treatment ought to be familiar to a beginning graduate student of pure mathematics.

Our brains are us. But we are neither happy, fulfilled, nor all that we 'should' (or maybe could) be. We have everything previous generations could have dreamed of, but it seems it's never quite enough. What's going on? Has it anything to do with the way those brains have developed, by any chance? Gillian Bridge takes us on a journey through time, history and the mysterious labyrinth that is the brain, investigating strange happenings and unlikely people on the way. (...) The Significance Delusion is a challenging explanation of our species' peculiar vulnerability to disorders of both thinking and social cohesion. It is a power pack of research, ideas, facts and fascinating real life stories which explores our species' obsession with meaning and significance. What does it all mean for me? What do I mean to you? The Significance Delusion is humorous as well as deeply serious, and it is the must read compilation of lifestyle advice for tomorrow's well-adjusted people. It is a book about what it takes to thrive and survive as an individual human and as a society. From it you will learn the meaning of life, and your place in the world. For parents, educators, thinkers, psychologists, psychotherapists and policy makers. (shrink)

In A General View of Positivism French philosopher Auguste Comte gives an overview of his social philosophy known as Positivism. Comte, credited with coining the term 'sociology' and one of the first to argue for it as a science, is concerned with reform, progress and the problem of social order in society. In this English edition of the work, published in 1865, he addresses the practical problems of implementing his philosophy or doctrine, as he also refers to Positivism, into society. (...) He believes that society evolves through a series of stages that are ruled by social laws and culminate in a superior form of social life. During this reorganisation of society, which will find its greatest supporters among women and the working class, a 'new moral power' will emerge. Under the motto 'love, order and progress' Comte wishes humanism to replace organised religion as the object of spiritual worship. (shrink)

This is an introduction to, and survey of, the constructive approaches to pure mathematics. The authors emphasise the viewpoint of Errett Bishop's school, but intuitionism. Russian constructivism and recursive analysis are also treated, with comparisons between the various approaches included where appropriate. Constructive mathematics is now enjoying a revival, with interest from not only logicans but also category theorists, recursive function theorists and theoretical computer scientists. This account for non-specialists in these and other disciplines.

We prove constructively that, in order to derive the uniform continuity theorem for pointwise continuous mappings from a compact metric space into a metric space, it is necessary and sufficient to prove any of a number of equivalent conditions, such as that every pointwise continuous mapping of [0, 1] into R is bounded. The proofs are analytic, making no use of, for example, fan-theoretic ideas.

The nature of modern constructive mathematics, and its applications, actual and potential, to classical and quantum physics, are discussed.

This paper explores the political potential of digital failure as a refusal to work in service of today’s dataveillance society. Moving beyond criticisms of flawed digital systems, this paper traces the moments of digital failure that seek to break, rather than fix, existing systems. Instead, digital failure is characterized by pesky data that sneaks through the cracks of digital capitalism and dissipates into the unproductive; it supports run-away data prone to misidentifications by digital marketers, coders, and content moderators; and it (...) celebrates data predisposed to “back-talk” with playful irreverence toward those that seek to bring order through normative categorization and moderation. I call these data entropic, fugitive, and queer and explore their mischievous practices through three case studies: the unaccountable data in identity resolution, public shaming of the ImageNet training data, and reading practices of sex worker and influencer, @Charlieshe. Together these case studies articulate the political potential of digital failure as a process of unbecoming the good data subject by pushing past the margins of legibility, knowability, and thinkability, to reveal what is made illegible, unknowable, and unthinkable to data’s seeing eye. As predictive analytics, automated decision-systems, and artificial intelligence take on increasingly central roles in public governance, digital failure reveals how data itself is a flawed concept prone to political abuse and social engineering to protect the interests of the powerful, while keeping those marginalized over-surveilled and underrepresented.

One of the chief aims of Donald Davidson's later work was to show that participation in a certain causal nexus involving two creatures and a shared environment–Davidson calls this nexus “triangulation”–is a metaphysically necessary condition for the acquisition of thought. This doctrine, I suggest, is aptly regarded as a form of what I call transcendental externalism. I extract two arguments for the transcendental-externalist doctrine from Davidson's writings, and argue that neither succeeds. A central interpretive claim is that the arguments are (...) primarily funded by a particular conception of the nature of non-human animal life. This conception turns out to be insupportable. The failure of Davidson's arguments presses the question of whether we could ever hope to arrive at far-reaching claims about the conditions for thought if we deny, as does Davidson, the legitimacy of the naturalistic project in the philosophy of mind.
