Glover's planning–control model accommodates a substantial number of findings from subjects who have motor deficits as a consequence of brain lesions. A number of consistently observed and robust findings are not, however, explained by Glover's theory; additionally, the claim that the IPL supports planning whereas the SPL supports control is not consistently supported in the literature.

We offer additional points that support a distributed semantic memory: the activation of representations that are modality-specific; patients with inferotemporal lesions fail to activate visual object representations in semantic tasks, although normal subjects do; direct activation of action systems from pictorial information, but not from words; patients who demonstrate superiority with abstract words fail to access perceptual representations.

In 1958 I set down some thoughts that arose from an attempt to consider epistemological problems on the assumptions that The biology of the human nervous system is relevant to epistemology and The human nervous system, like every other object of biological investigation, is a product of evolution by natural selection. These thoughts lay more or less neglected until they were brought stunningly to mind by Professor George Gaylord Simpson's [1] recent paper on “Biology and the Nature of Science”. In (...) that paper Professor Simpson writes: “Still another consideration seems to me the most interesting of all, and yet I have never seen it clearly expressed elsewhere. It is, in a sense a validation of the ‘animal faith’ given by Russell … as sole basis for assuming that we really can obtain knowledge of the outer world. The fact is that man originated by a slow process of evolution guided by natural selection. At every stage in this long progression our ancestors necessarily had adaptive reactions to the world around them. As behavior and sense organs became more complex, perception of sensations from those organs obviously maintained a realistic relationship to the environment. To put it crudely but graphically, the monkey who did not have a realistic perception of the tree branch he jumped for was soon a dead monkey-and therefore did not become one of our ancestors. Our perceptions do give true, even though not complete, representations of the outer world because that was and is a biological necessity.”. (shrink)

I review arguments demonstrating how the concept of “particle” numbers arises in the form of equidistant energy eigenvalues of coupled harmonic oscillators representing free fields. Their quantum numbers (numbers of nodes of the wave functions) can be interpreted as occupation numbers for objects with a formal mass (defined by the field equation) and spatial wave number (“momentum”) characterizing classical field modes. A superposition of different oscillator eigenstates, all consisting of n modes having one node, while all others have none, defines (...) a non-degenerate “n-particle wave function”. Other discrete properties and phenomena (such as particle positions and “events”) can be understood by means of the fast but continuous process of decoherence: the irreversible dislocalization of superpositions. Any wave-particle dualism thus becomes obsolete. The observation of individual outcomes of this decoherence process in measurements requires either a subsequent collapse of the wave function or a “branching observer” in accordance with the Schrödinger equation—both possibilities applying clearly after the decoherence process. Any probability interpretation of the wave function in terms of local elements of reality, such as particles or other classical concepts, would open a Pandora’s box of paradoxes, as is illustrated by various misnomers that have become popular in quantum theory.

This book explores how and when biology emerged as a science in Germany. Beginning with the debate about organism between Georg Ernst Stahl and Gottfried Leibniz at the start of the eighteenth century, John Zammito traces the development of a new research program, culminating in 1800, in the formulation of developmental morphology. He shows how over the course of the century, naturalists undertook to transform some domains of natural history into a distinct branch of natural philosophy, which attempted not (...) only to describe but to explain the natural world and became, ultimately, the science of biology.

The study aimed to identify the knowledge management processes and their role in achieving competitive advantage at Al-Quds Open University. The study was based on the descriptive analytical method, and the study population consists of academic and administrative staff in each of the branches of Al-Quds Open University in (Tulkarm, Nablus and Jenin). The researchers selected a sample of the study population by the intentional non-probability method, the size of (70) employees. A questionnaire was prepared and supervised by a number (...) of specialists in order to obtain the results of the study. The study concluded that there is a positive direct relationship, that is, the higher the degree of application of knowledge management processes, the greater the degree of competitive advantage. Knowledge Technology came first with a score of 80.02% on all items. Competitive advantage came second with 81.74%. In the third place came "knowledge generation" where the total score on all paragraphs in this area (78.24%). In the fourth place, "knowledge transfer" (77.21%). "Developing and storing knowledge" came in fifth place (77.13%). "Acquisition of knowledge" came in sixth place (76.45%). Knowledge Organization ranked seventh (74.26%). The study recommended that the university should enable the employees to benefit from the experiences and expertise available to help generate knowledge. The University encourages the creation of knowledge through the system of incentives and open the way for creators to apply their creations and spread and invest in excellence and creativity. The university should design work performance levels based on the integration of knowledge and organize it according to policies that support freedom of research. The need for Palestinian universities to adopt a knowledge management approach. The need to adopt a system of incentives that rewards cognitive efforts, and give workers enough freedom to enable them to apply their knowledge. (shrink)

Brouwer's views on the foundations of mathematics have inspired the study of intuitionistic logic, including the study of the intuitionistic propositional calculus and its extensions. The theory of these systems has become an independent branch of logic with connections to lattice theory, topology, modal logic and other areas. This paper aims to present a modern account of semantics for intuitionistic propositional systems. The guiding idea is that of a hierarchy of semantics, organized by increasing generality: from the least general (...) Kripke semantics on through Beth semantics, topological semantics, Dragalin semantics, and finally to the most general algebraic semantics. While the Kripke, topological, and algebraic semantics have been extensively studied, the Beth and Dragalin semantics have received less attention. We bring Beth and Dragalin semantics to the fore, relating them to the concept of a nucleus from pointfree topology, which provides a unifying perspective on the semantic hierarchy. (shrink)

Book synopsis: Aristotle's probing inquiry into some of the fundamental problems of philosophy, The Metaphysics is one of the classical Greek foundation-stones of western thought, translated from the with an introduction by Hugh Lawson-Tancred in Penguin Classics. The Metaphysics presents Aristotle's mature rejection of both the Platonic theory that what we perceive is just a pale reflection of reality and the hard-headed view that all processes are ultimately material. He argued instead that the reality or substance of things lies in (...) their concrete forms, and in so doing he probed some of the deepest questions of philosophy: What is existence? How is change possible? And are there certain things that must exist for anything else to exist at all? The seminal notions discussed in The Metaphysics - of 'substance' and associated concepts of matter and form, essence and accident, potentiality and actuality - have had a profound and enduring influence, and laid the foundations for one of the central branches of Western philosophy. Hugh Lawson-Tancred's lucid translation is accompanied by a stimulating introduction in which he highlights the central themes of one of philosophy's supreme masterpieces. Aristotle (384-22 BC) studied at the Academy of Plato for 20 years and then established his own school and research institute, 'The Lyceum'. His writings, which were of extraordinary range, profoundly affected the whole course of ancient and medieval philosophy and are still eagerly studied and debated by philosophers today. (shrink)

In recent times Wittgenstein's work in logic has had an influence on other branches of philosophy. I am thinking, in particular, of social philosophy and the philosophy of religion. In these branches, Wittgenstein's followers have made much use of his notion of a language game. It has been argued, for example, that religion forms a language game of its own, having its own standards of reason, and is therefore not subject to criticism from outside. This argument has given rise to (...) controversy, some seeing it as a subtle attempt by the religious to evade criticism. I have come myself to feel that the notion of a language game has been put to uses with which Wittgenstein himself might not have agreed, or, if he had, would have been wrong to do so. In order to explain what I mean I should like to look closely at the opening section of Peter Winch's article ‘Understanding a Primitive Society’. (shrink)

In the modern world of total technologization, scientific knowledge devoid of worldview correction (humanitarian expertise) carries a threatening tendency of self-denial: without a constant, philosophically correct transformation of objective knowledge about certain fragments (branches) of the surrounding reality into human knowledge (questions) about itself, the practical effectiveness of such knowledge inevitably accumulates in itself the threat of practical helplessness. Aim and the tasks of the research. Based on an in-depth analysis of the category of existence, as well as on modern (...) philosophical reflections on the methodological and cognitive insolvency of the idea of the world, to find out the real meaning of those changes that this idea meaningfully undergoes in the conditions of the modern total technologization of human life. The research methodology. From a methodological point of view, the author prefers a dialectical approach, considering the analyzed phenomena, regardless of the mode of their reality, in their development and internally contradictory essence. H. Plesner’s theory of eccentric positionality serves as a certain base point for the analysis of human nature and, accordingly, the world of human existence. Research results: The problematic existence of the world and the epistemological «failure» of the corresponding category, declared in some modern philosophical reflections, are connected exclusively with its anthropological and worldview function, which is based on the fundamental uncertainty of a man’s place in the world. The «worthlessness» («futility») of worldview thematization is derived from the allencompassing inability of the human figure in the world, from that «emptiness» and «invisibility» (specific own transparency) of the spiritual dimension of human existence, on which, however, this existence is based. Discussion. The human «option» of fulfilling the unity of living being can be characterized as extremely intense. In this variant, the phylogenetic line of development turns into an ontogenetic point of worldliness devoid of predetermined content, a fundamentally new type of integration. The horizons of such integration far exceed primarily because of its understanding. And the subject of such a meaningful life is forced to integrate everything that happens to him every time into a certain system (synthesis) of the world. That subjectivity the world has distinguishes the subject from the thing. Subjectivity and the world mutually belong to each other - they are correlative. A thing exists because it is what it is. The subject (and with it his world) does not exist like that. A subject is how and to what it relates. But the relation «how» and «to what» is not carried out completely anew and isolated every time, but exists in its multiplicity in a certain relationship. Each individual case, each individual action (method of action) acquires its meaning from a wider, structured context – in whole or in part. This context is the «world», the «life world» of the real subject, or the «world» as an anthropological idea. Conclusions. The task of modern humanitarianism is not only to find opportunities for rational use of the fact of the fundamental openness of the human being, but also to cultivate the ability to reconcile a man with himself, to accept himself. This gives us certain reasons to hope for the enduring significance of worldview thematization. Criticism regarding the seemingly paradoxical conclusion that to become a man, one must already be one, could be considered fair, but only if one does not take into account the principled nature of such an aphoristic position, because this is exactly how the human world exists - as the art of tolerance uncertainty.

The beginnings of Hegel’s interest in “logic” as a branch of philosophy are somewhat obscure. In a lecture of 1830 Schelling claimed that Hegel first began to attend to the subject only because “his friends at the University” suggested that it was a good topic for his lectures because it was being neglected. Schelling’s object by then was evidently to suggest that Hegel’s “logic” had always been a superficial pretense. But Hegel was alive to contradict him. So I think (...) his statement of the facts must be right as far as it goes. I do not therefore believe that Hegel came to Jena with any “logical” manuscripts. In my view, it was Schelling himself—especially in his System of Transcendental Idealism —who sparked Hegel’s interest in the subject. (shrink)

Albert Einstein's attitude towards quantum mechanics—and statistical physics in general—was a puzzle to many of his contemporaries, and has remained a puzzle to the present. Though he made many significant contributions to statistical physics, he continually refused to regard that branch of science as fundamental. The present essay demonstrates that his attitude towards statistical physics was formed during his earliest investigations—between 1901 and 1903. In particular, it is shown that in Einstein's view, statistical laws are based upon non-statistical assumptions. (...) This view influenced much of his later thinking. A few illustrations are offered, concluding with a discussion of his opposition to quantum mechanics. (shrink)

1. "The map of logic." Comparatively recently, Kant's words to the effect that in the two thousand years since Aristotle logic had made "not a single step forward and, all things considered, it seems to be a fully finished and completed discipline" used to be quoted widely and not unsympathetically. Today, however, there are works about logic in which the listing of logical disciplines runs into the dozens. In this regard the attempt by the American logician N. Rescher to compile (...) a diagram or "map of logic," in which the list of the branches of logic takes up several pages, is noteworthy. Also characteristic is the following statement by one of the major modern representatives of mathematical logic, S. Kleene: "Since the discovery of non-Euclidean geometries by Lobachevsky and Bolyai , it has become clear that different systems of geometries are conceptually equally possible…. Identically, there are different logics.". (shrink)

Matthew H. Bowker offers a novel analysis of "experience": the vast and influential concept that has shaped Western social theory and political practice for the past half-millennium. While it is difficult to find a branch of modern thought, science, industry, or art that has not relied in some way on the notion of "experience" in defining its assumptions or aims, no study has yet applied a politically-conscious and psychologically-sensitive critique to the construct of experience. Doing so reveals that most (...) of the qualities that have been attributed to experience over the centuries — particularly its unthinkability, its correspondence with suffering, and its occlusion of the self — are part of unlikely fantasies or ideologies. By analyzing a series of related cases, including the experiential education movement, the ascendency of trauma theory, the philosophy of the social contract, and the psychological study of social isolation, the book builds a convincing case that ideologies of experience are invoked not to keep us close to lived realities and ‘things-in-themselves,’ but, rather, to distort and destroy true knowledge of ourselves and others. In spite of enduring admiration for those who may be called champions of experience, such as Michel de Montaigne, Ralph Waldo Emerson, and others treated throughout the work, the ideologies of experience ultimately discourage individuals and groups from creating, resisting, and changing our experience, urging us instead to embrace trauma, failure, deprivation, and self-abandonment.

Sydney Shoemaker has claimed that functionalism, a theory about mental states, implies a certain theory about the identity over time of persons, the entities that have mental states. He also claims that persons can survive a "Brain-State-Transfer" procedure. My examination of these claims includes description and analysis of imaginary cases, but-notably-not appeals to our "intuitions" concerning them. It turns out that Shoemaker's basic insight is correct: there is a connection between the two theories. Specifically, functionalism implies that "non-branching functional continuity" (...) is sufficient for personal identity. But there is no implication that it is necessary. And the "BST" procedure may not preserve functional continuity. I consider several possibilities. On what may be the most attractive, the survivor of this-or any similar-procedure is not identical with the original person, but related to him or her as are the survivors in a case of fission.

In patients with pain characterized by a painful focus and allodynia, the painful symptoms arise from altered central processing that is initiated and subsequently maintained by persistent input from nociceptive afferents. Treatments directed at this normal consequence of persistent input are inherently limited. The most efficacious treatments will target the pathology, the various sources of ongoing nociceptor input.

The individual soul is an ageless idea, attested in prehistoric times by the oral traditions of all cultures. But as far as we know, it enters history in ancient Egypt. I will begin with the individual soul in ancient Egypt, then recount the birth of the world soul in the Pythagorean community of ancient Greece, and trace it through the Western Esoteric Tradition until its demise in Kepler's writings, along with the rise of modern science, around 1600 CE. Then I (...) tell of the rebirth of the world soul recently, in new branches of mathematics. (shrink)

Embodied cognition is a well-established and increasingly influential branch of the cognitive, neural, and psychological sciences. Unlike embodied cognition, extended cognition is not as well-established or influential. Our goal is to defend the idea that if cognition is truly embodied, then it is embodied in systems, and if it is embodied in systems, then it extends beyond animal boundaries. In order to demonstrate this, we situate the idea of extended cognitive systems in a historical context. Then, we present a (...) theoretical and methodological framework for investigating extended cognitive systems. Finally, we discuss some potential experimental work that could adjudicate the existence of extended cognitive systems. (shrink)
