In lieu of an abstract, here is a brief excerpt of the content:Sighs and Tears:Biological Signals and John Donne's "Whining Poetry"Michael A. WinkelmanPhebe: Good shepherd, tell this youth what 'tis to love. Silvius: It is to be all made of sighs and tears...—Shakespeare, As You Like It (5.2.83–84)ISighs and tears permeate John Donne's poetry, as well they should. Crying in particular functions as a costly signal in biological terms: a blatant, physiologically-demanding, involuntary indicator of hurt feelings. "Tears dim mine (...) eyes," laments Donne's Sappho ("Sappho to Philaenis," l. 56); they are "Fruits of much grief" in "A Valediction of Weeping" (l. 7).1 The theory of costly signaling, related to the handicap principle, was developed fairly recently by Israeli zoologists Amotz and Avishag Zahavi. As the Zahavis explain: "in order to be effective, signals have to be reliable; in order to be reliable, signals have to be costly."2 Initially their idea was resisted, but it has since become widely accepted and it has proven very helpful in making sense of both animal and human behavior. Wasteful conspicuous consumption among upper-class Americans, as noted a century ago by sociologist Thorstein Veblen, exemplifies this handicap principle in action. Like gazelles jumping in place or stotting rather than running away when wolves appear, it indicates fitness by flaunting excess resources.Shedding tears when feeling sad is an evolved human adaptation that broadcasts unhappiness. The wailing of infants demands attention, and crying does something similar for grown-ups: among other things, it tests the commitment of hearers to appease the distressed. For instance, in Chaucer's tragic medieval romance Troilus and Criseyde, Pandarus advises [End Page 329] Troilus to provoke a suitable reaction from Criseyde by embellishing his billet-doux: "Towchyng thi lettre... Biblotte it with thi teris ek a lite" (touching thy letter... Be-blot it with thy tears a little).3 Early modern authors also knew their importance. In the words of Robert Herrick, "tears are tongues," while Claudius suspects that "There's matter in these sighs, these profound heaves" (Hamlet, 4.1.1).4As a case in point, Donne was overwhelmed by the death of his dear wife Anne in 1617. As his contemporaneous biographer Izaak Walton reported: "his very soul was elemented of nothing but sadness; now, grief took so full a possession of his heart, as to leave no place for joy."5 Donne even hoped to be literally entombed with her soon: "as the grave is become her house, so I would hasten to make it mine also; that we two might there make our beds together in the dark" (Walton, p. 51). His miserable mood was revealed in his initial sermon after her demise:His first motion from his house was to preach, where his beloved wife lay buried (in St. Clement's Church, near Temple-Bar, London) and his text was a part of the Prophet Jeremiah's Lamentation: "Lo, I am the man that have seen affliction."And indeed, his very words and looks testified him to be truly such a man; and they, with the addition of his sighs and tears expressed in his Sermon, did so work upon the affections of his hearers as melted and molded them into a companionable sadness; and so they left the Congregation.(Walton, p. 52)Listeners responded in kind to his honest confessions, a textbook illustration of the empathy generated by crying. (A related issue—how and why literature affects audiences so strongly—is currently generating some very interesting work from New Humanists investigating the question from an evolutionary perspective.)These qualities make sighs and tears fundamental to love poetry. In other words, writers deploy them because they reflect universal states of mind, rather than originating as some arbitrary, socially-constructed literary device. The copious opening sonnet of Petrarch's magnificent Rime sparse codifies the theme:6You who can hear in scattered rhymes the soundof all that sighing which once fed my heartin my first youthful error, when in partI was a person of a different kind—my changing manner as I weep and reason, [End Page 330] between vain aspirations and vain grief,leads everyone who has known...

Anthropology of Consciousness, Volume 32, Issue 2, Page 154-181, Autumn 2021.

Neurotheological approaches provide an important bridge between scientific and religious perspectives. These approaches have, however, generally neglected the implications of a primordial form of spiritual healing—shamanism. Cross‐cultural studies establish the universality of shamanic practices in hunter‐gatherer societies around the world and across time. These universal principles of shamanism reflect underlying neurological processes and provide a basis for an evolutionary theology. The shamanic paradigm involves basic brain processes, neurognostic structures, and innate brain modules. This approach reveals that universals of shamanism such (...) as animism, totemism, soul flight, animal spirits, and death‐and‐rebirth experiences reflect fundamental brain operations and structures of consciousness. The shamanic paradigm can contribute to a reconciliation of scientific and religious perspectives by providing a universalistic biopsychosocial framework that explicates the biological underpinnings of spiritual experiences and practices and provides a basis for neurotheology and evolutionary theology approaches.

The numerous perspectives offered on consciousness reflect a multifaceted phenomenon that results from a system of relations. An etymological approach identifies linguistic roots of the meanings of consciousness and illustrates their concern with self-referenced informational relationships of an organism with its environment, a "knowing system" formed in the epistemological relations between knower and known. Common elements of contemporary models suggest that consciousness involves interacting components of a system, including: attention-awareness; phenomenal experiences; self reference; action-behavior, including representations and learning; use of (...) information; interpretation of meaning; goal-directed behavior; and systems of social reference. It is suggested that manifestations of consciousness through the physical properties of the brain are universally represented in language. A preliminary systems model of consciousness is outlined with widespread lexical roots proposed as a culture-neutral framework for constructing theories of consciousness and identifying cognitive constructs which reveal the epistemological roots of consciousness within Indo-European traditions.

Soul belief is a universal of human culture and belief in multiple souls is common, especially in pre-modern traditions. This essay illustrates how a three-folded structure appears in the soul concepts of Mongolian shamanistic traditions. The reported accounts of the three souls among various Mongolian ethnic groups are somewhat divergent — especially in their consciousness-related attributes — which may reflect the cultural bias of data collectors, inconsistencies between data providers, and the evolution of these concepts due to historical events, socio-economic (...) changes, and external cultural influences. Despite these confounding effects, the soul concept of Mongolian shamanism is similar in its pluralism to the beliefs of many other cultures. Mongolian Indigenous concepts and their descriptions reveal key elements of consciousness. Although these soul concepts evoke spiritual interpretations, they nevertheless reflect aspects of an innately-disposed mindset which extends conceptualizations of consciousness beyond mind-body dualism.

This article reviews the origins of the concept of the shaman and the principal sources of controversy regarding the existence and nature of shamanism. Confusion regarding the nature of shamanism is clarified with a review of research providing empirical support for a cross-cultural concept of shamans that distinguishes them from related shamanistic healers. The common shamanistic universals involving altered states of consciousness are examined from psychobiological perspectives to illustrate shamanism’s relationships to human nature. Common biological aspects of altered states of (...) consciousness help explain the origins of shamanism while social influences on this aspect of human nature help to explain the diverse manifestations of shamanistic phenomena involving an elicitation of endogenous healing responses.

This paper reviews some of the evidence indicating that hallucinogens or psychedelic substances have therapeutic effects. The general character hallucinogen use in non- Western societies is briefly reviewed to present data about the characteristic beliefs and uses associated with these substances. Evidence for therapeutic effectiveness is addressed from several perspectives: the findings from clinical medicine on effects of LSD; a general model of altered states of consciousness, their physiological characteristics, and therapeutic effects; and laboratory studies of physiological, sensory, emotional, behavioral, (...) and cognitive effects of hallucinogens. These findings illuminate the general psychophysiological effects of hallucinogens and their consciousness altering and therapeutic mechanisms. (shrink)

In this book, Michael Arbib, a researcher in artificial intelligence and brain theory, joins forces with Mary Hesse, a philosopher of science, to present an integrated account of how humans 'construct' reality through interaction with the social and physical world around them. The book is a major expansion of the Gifford Lectures delivered by the authors at the University of Edinburgh in the autumn of 1983. The authors reconcile a theory of the individual's construction of reality as a network (...) of schemas 'in the head' with an account of the social construction of language, science, ideology and religion to provide an integrated schema-theoretic view of human knowledge. The authors still find scope for lively debate, particularly in their discussion of free will and of the reality of God. The book integrates an accessible exposition of background information with a cumulative marshalling of evidence to address fundamental questions concerning human action in the world and the nature of ultimate reality.

Bishop and Trout here present a unique and provocative new approach to epistemology. Their approach aims to liberate epistemology from the scholastic debates of standard analytic epistemology, and treat it as a branch of the philosophy of science. The approach is novel in its use of cost-benefit analysis to guide people facing real reasoning problems and in its framework for resolving normative disputes in psychology. Based on empirical data, Bishop and Trout show how people can improve their reasoning by relying (...) on Statistical Prediction Rules. They then develop and articulate the positive core of the book. Their view, Strategic Reliabilism, claims that epistemic excellence consists in the efficient allocation of cognitive resources to reliable reasoning strategies, applied to significant problems. The last third of the book develops the implications of this view for standard analytic epistemology; for resolving normative disputes in psychology; and for offering practical, concrete advice on how this theory can improve real people's reasoning. This is a truly distinctive and controversial work that spans many disciplines and will speak to an unusually diverse group, including people in epistemology, philosophy of science, decision theory, cognitive and clinical psychology, and ethics and public policy.

Science and philosophy study well-being with different but complementary methods. Marry these methods and a new picture emerges: To have well-being is to be "stuck" in a positive cycle of emotions, attitudes, traits and success. This book unites the scientific and philosophical worldviews into a powerful new theory of well-being.

The article analyzes the neural and functional grounding of language skills as well as their emergence in hominid evolution, hypothesizing stages leading from abilities known to exist in monkeys and apes and presumed to exist in our hominid ancestors right through to modern spoken and signed languages. The starting point is the observation that both premotor area F5 in monkeys and Broca's area in humans contain a “mirror system” active for both execution and observation of manual actions, and that F5 (...) and Broca's area are homologous brain regions. This grounded the mirror system hypothesis of Rizzolatti and Arbib (1998) which offers the mirror system for grasping as a key neural “missing link” between the abilities of our nonhuman ancestors of 20 million years ago and modern human language, with manual gestures rather than a system for vocal communication providing the initial seed for this evolutionary process. The present article, however, goes “beyond the mirror” to offer hypotheses on evolutionary changes within and outside the mirror systems which may have occurred to equip Homo sapiens with a language-ready brain. Crucial to the early stages of this progression is the mirror system for grasping and its extension to permit imitation. Imitation is seen as evolving via a so-called simple system such as that found in chimpanzees (which allows imitation of complex “object-oriented” sequences but only as the result of extensive practice) to a so-called complex system found in humans (which allows rapid imitation even of complex sequences, under appropriate conditions) which supports pantomime. This is hypothesized to have provided the substrate for the development of protosign, a combinatorially open repertoire of manual gestures, which then provides the scaffolding for the emergence of protospeech (which thus owes little to nonhuman vocalizations), with protosign and protospeech then developing in an expanding spiral. It is argued that these stages involve biological evolution of both brain and body. By contrast, it is argued that the progression from protosign and protospeech to languages with full-blown syntax and compositional semantics was a historical phenomenon in the development of Homo sapiens, involving few if any further biological changes. Key Words: gestures; hominids; language evolution; mirror system; neurolinguistics; primates; protolanguage; sign language; speech; vocalization. (shrink)

Here, we argue that any neurobiological theory based on an experience/function division cannot be empirically confirmed or falsified and is thus outside the scope of science. A ‘perfect experiment’ illustrates this point, highlighting the unbreachable boundaries of the scientific study of consciousness. We describe a more nuanced notion of cognitive access that captures personal experience without positing the existence of inaccessible conscious states. Finally, we discuss the criteria necessary for forming and testing a falsifiable theory of consciousness.

While many books have appeared on limited aspects of one subfield or another of brain theory and neural networks, the (...) Handbookcovers the entire sweep of topics—from detailed models of single neurons, analyses of a wide variety of biological neural networks, and connectionist studies of psychology and language, to mathematical analyses of a variety of abstract neural networks, and technological applications of adaptive, artificial neural networks. The excitement, and the frustration, of these topics is that they span such a broad range of disciplines including mathematics, statistical physics and chemistry, neurology and neurobiology, and computer science and electrical engineering as well as cognitive psychology, artificial intelligence, and philosophy. Thus, much effort has gone into making the Handbookaccessible to readers with varied backgrounds while still providing a clear view of much of the recent, specialized research in specific topics. The heart of the book, part III, comprises of 267 original articles by leaders in the various fields, arranged alphabetically by title. Parts I and II, written by the editor, are designed to help readers orient themselves to this vast range of material. Part I, Background, introduces several basic neural models, explains how the present study of brain theory and neural networks integrates brain theory, artificial intelligence, and cognitive psychology, and provides a tutorial on the concepts essential for understanding neural networks as dynamic, adaptive systems. Part II, Road Maps, provides entry into the many articles of part III through an introductory "Meta-Map" and twenty-three road maps, each of which tours all the Part III articles on the chosen theme.

Although our subjective impression is of a richly detailed visual world, numerous empirical results suggest that the amount of visual information observers can perceive and remember at any given moment is limited. How can our subjective impressions be reconciled with these objective observations? Here, we answer this question by arguing that, although we see more than the handful of objects, claimed by prominent models of visual attention and working memory, we still see far less than we think we do. Taken (...) together, we argue that these considerations resolve the apparent conflict between our subjective impressions and empirical data on visual capacity, while also illuminating the nature of the representations underlying perceptual experience.

Are thought experiments nothing but arguments? I argue that it is not possible to make sense of the historical trajectory of certain thought experiments if one takes them to be arguments. Einstein and Bohr disagreed about the outcome of the clock-in-the-box thought experiment, and so they reconstructed it using different arguments. This is to be expected whenever scientists disagree about a thought experiment's outcome. Since any such episode consists of two arguments but just one thought experiment, the thought experiment cannot (...) be the arguments. (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)

The generality problem is widely considered to be a devastating objection to reliabilist theories of justification. My goal in this paper is to argue that a version of the generality problem applies to all plausible theories of justification. Assume that any plausible theory must allow for the possibility of reflective justification—S's belief, B, is justified on the basis of S's knowledge that she arrived at B as a result of a highly (but not perfectly) reliable way of reasoning, R. The (...) generality problem applies to all cases of reflective justification: Given that is the product of a process-token that is an instance of indefinitely many belief-forming process-types (or BFPTs), why is the reliability of R, rather than the reliability of one of the indefinitely many other BFPTs, relevant to B's justificatory status? This form of the generality problem is restricted because it applies only to cases of reflective justification. But unless it is solved, the generality problem haunts all plausible theories of justification, not just reliabilist ones. (shrink)

Epistemic responsibility involves at least two central ideas. (V) To be epistemically responsible is to display the virtue(s) epistemic internalists take to be central to justification (e.g., coherence, having good reasons, fitting the evidence). (C) In normal (non-skeptical)circumstances and in thelong run, epistemic responsibility is strongly positively correlated with reliability. Sections 1 and 2 review evidence showing that for a wide range of real-world problems, the most reliable, tractable reasoning strategies audaciously flout the internalist''s epistemic virtues. In Section 3, I (...) argue that these results force us to give up either (V), our current conception of what it is to be epistemically responsible, or (C) the responsibility-reliability connection. I will argue that we should relinquish (V). This is likely to reshape our epistemic practices. It will force us to alter our epistemic judgments about certain instances of reasoning, to endorse some counterintuitive epistemic prescriptions, and to rethink what it is for cognitive agents to be epistemically responsible.

If a brain is uploaded into a computer, will consciousness continue in digital form or will it end forever when the brain is destroyed? Philosophers have long debated such dilemmas and classify them as questions about personal identity. There are currently three main theories of personal identity: biological, psychological, and closest continuer theories. None of these theories can successfully address the questions posed by the possibility of uploading. I will argue that uploading requires us to adopt a new theory of (...) identity, psychological branching identity. Psychological branching identity states that consciousness will continue as long as there is continuity in psychological structure. What differentiates this from psychological identity is that it allows identity to continue in multiple selves. According to branching identity, continuity of consciousness will continue in both the original brain and the upload after nondestructive uploading. Branching identity can also resolve long standing questions about split-brain syndrome and can provide clear predictions about identity in even the most difficult cases imagined by philosophers.

First-ever comprehensive introduction to the major new subject of quantum computing and quantum information.

My essay, “Multi-modal argumentation” was published in the journal, _Philosophy of the Social Sciences,_ in 1994. This information appeared again in my book, _Coalescent argumentation_ in 1997. In the ensuing twenty years, there have been many changes in argumentation theory, and I would like to take this opportunity to examine my now middle-aged theory in light of the developments in our discipline. I will begin by relating how a once keen intended lawyer and then formal logician ended up in argumentation (...) theory. (If you do not care to read this bit of autobiography, skip to Section 2).

Thirty years ago, I elaborated on a position that could be seen as a compromise between an "extreme," symbol-based AI, and a "neurochemical reductionism" in AI. The present article recalls aspects of the espoused framework of schema theory that, it suggested, could provide a better bridge from human psychology to brain theory than that offered by the symbol systems of A. Newell and H. A. Simon.

This article is concerned with developing a philosophical approach to a number of significant changes to academic publishing, and specifically the global journal knowledge system wrought by a range of new digital technologies that herald the third age of the journal as an electronic, interactive and mixed-media form of scientific communication.

The paper (...) is the result of a collective writing process. (shrink)

Computational modeling of the macaque brain grounds hypotheses on the brain of LCA-m. Elaborations thereof provide a brain model for LCA-c. The Mirror System Hypothesis charts further steps via imitation and pantomime to protosign and protolanguage on the path to a "language-ready brain" in Homo sapiens, with the path to speech being indirect. The material poses new challenges for both experimentation and modeling.
