The domains of quantum theory and general relativity overlap in situations where quantum mechanical effects cannot be ignored. In order to deal with this overlap of theoretical domains, there has been a tendency to apply the rules of quantum field theory to the classical gravitational field equations and without much regard for the implications of the whole enterprise. The gravitational version of the asymmetric ageing of identical biological specimens shows that curved spacetime is not dispensable. This result is used to (...) conclude that the particle-based interpretations of quantum gravity are not acceptable. (shrink)

Examines the relationship between sport and education from both social and moral points of view. The text argues that sport has such a vital role to play in society that it should be an integral part of the curriculum. It presents guidelines for an effective teaching of sports in schools.

This book examines the philosophical foundations of the realist view of the progress of science as cumulative. It is a view that has recently been faced with a number of powerful attacks in which successive scientific theories are seen, not as extending their scope and honing their explanations, but as incommensurable. There is, it is held, in principle no way of establishing that they are about the same things. From the voluminous literature on the topic, Dr Smith has selected relevantly (...) and incisively and his exposition of the contending arguments is vigourous and clear, without undue technicality. As an explication and defence of realism it will interest all those concerned with this basic question in the philosophy of science and the philosophy of language. (shrink)

Robert Frost is by far the most celebrated major American poet of the twentieth century. In part, this is because his poetry seems, on the surface, to be so accessible, even homey. But Frost was not just a powerful writer of popular lyric and narrative verse, argues Peter J. Stanlis in this major contribution to American literary study and philosophy. Rather, his work is deeply rooted in a complex philosophical dualism that opposes both idealistic monism, centered in spirit, and (...) scientific positivism, which posits that the universe can be understood as nothing but matter. In _Robert Frost: The Poet as Philosopher,_ Stanlis shows how Frost’s philosophical dualism of spirit and matter is perceived through metaphors and applied to science, religion, art, education, and society. He further argues that Frost’s dualism provides a critique of the monistic forces that were instrumental in the triumph of twentieth-century totalitarianism. Thoroughly informed by his twenty-three year friendship and correspondence with Frost, Stanlis’s landmark volume is the first attempt to deal with the poet’s philosophy in a systematic manner. It will appeal not only to fans of Frost but to all who understand poetry as a form of revelation for understanding human nature. (shrink)

A commentary on Richard Joyce's The Evolution of Morality.

The paradox in Inquiry in Plato's Meno raises the fundamental epistemological problem of how one can come to know the basic and primary criteria of philosophical reasoning. Two key tenets of the Socratic search for definitions underlie the paradox. First, Socrates argues in both the Euthyphro and Hippias Major, that knowledge of particular instances of a given Form presupposes knowledge of the universal Form. Secondly, Socrates insists in the Meno that knowledge of essence logically preceeds knowledge of a Form's other (...) properties. Taken together, these two principles entail that one cannot gain knowledge of essence either by inductive or by deductive reasoning. Thus when Socrates seeks to determine the correct definition of the essence of virtue, he faces the apparently insuperable problem of having no rational method for establishing the proper definition. The paradox of inquiry states in effect that Socratic elenchus is absurd because it posits an essence both as the goal and the necessary starting point of rational argumentation. ;It is in the face of this serious skeptical dilemma that Plato articulates a profoundly original conception of reasoning. According to Plato, the solution to the paradox is that reasoning toward a definition of essences involves raising to explicit consciousness one's implicit knowledge of the very essence being sought. The description of this process as a recalling of knowledge actually acquired in an earlier life is intended only as a metaphor: it illuminates the process of bringing to full awareness what one already implicitly knows. Both the problem and the solution presented in the Meno exhibit the characteristic Platonic interrelationship of metaphysicis and epistemology. When Socrates asks for a definition of virtue in the Meno, he means to uncover the nature of a Form which exists separately from its examples. Socratic definition is neither a form of conceptual analysis nor an analysis of immanent characteristics in particulars. The failure of many commentators to appreciate the recollection theory often derives from a failure to comprehend these metaphysical dimensions of Plato's solution. (shrink)

The brain displays both the anatomical features of a vast amount of interconnected topological mappings as well as the functional features of a nonlinear, metastable system at the edge of chaos, equipped with a phase space where mental random walks tend towards lower energetic basins. Nevertheless, with the exception of some advanced neuro-anatomic descriptions and present-day connectomic research, very few studies have been addressing the topological path of a brain embedded or embodied in its external and internal environment. Herein, by (...) using new formal tools derived from algebraic topology, we provide an account of the metastable brain, based on the neuro-scientific model of Operational Architectonics of brain-mind functioning. We introduce a “topodynamic” description that shows how the relationships among the countless intertwined spatio-temporal levels of brain functioning can be assessed in terms of projections and mappings that take place on abstract structures, equipped with different dimensions, curvatures and energetic constraints. Such a topodynamical approach, apart from providing a biologically plausible model of brain function that can be operationalized, is also able to tackle the issue of a long-standing dichotomy: it throws indeed a bridge between the subjective, immediate datum of the naïve complex of sensations and mentations and the objective, quantitative, data extracted from experimental neuro-scientific procedures. Importantly, it opens the door to a series of new predictions and future directions of advancement for neuroscientific research. (shrink)

The discrepancy between syntax and semantics is a painstaking issue that hinders a better comprehension of the underlying neuronal processes in the human brain. In order to tackle the issue, we at first describe a striking correlation between Wittgenstein's Tractatus, that assesses the syntactic relationships between language and world, and Perlovsky's joint language-cognitive computational model, that assesses the semantic relationships between emotions and “knowledge instinct”. Once established a correlation between a purely logical approach to the language and computable psychological activities, (...) we aim to find the neural correlates of syntax and semantics in the human brain. Starting from topological arguments, we suggest that the semantic properties of a proposition are processed in higher brain's functional dimensions than the syntactic ones. In a fully reversible process, the syntactic elements embedded in Broca's area project into multiple scattered semantic cortical zones. The presence of higher functional dimensions gives rise to the increase in informational content that takes place in semantic expressions. Therefore, diverse features of human language and cognitive world can be assessed in terms of both the logic armor described by the Tractatus, and the neurocomputational techniques at hand. One of our motivations is to build a neuro-computational framework able to provide a feasible explanation for brain's semantic processing, in preparation for novel computers with nodes built into higher dimensions.

First of all, we would like to gratefully thank all commentators for the attention and effort they have put into reading and responding to our review paper [this issue] and for useful observations that suggest novel applications for our framework. We understand and accept that some of our claims might appear controversial and raise skepticism, because the overall neural framework we have proposed is difficult to frame in established categories, given its strong multidisciplinary character. To make an example, Elsevier is (...) publishing the British Neuroscience Association (BNA) 2017 Special Issue Collection. However, our paper could not fully fit in any of their Special Issues—attention, motivation, behavior; sensory and motor systems; novel treatments and translational neuroscience; genetics and epigenetics; learning and memory; neurodegenerative disorders and ageing; developmental neuroscience; neuronal, glial and cellular mechanisms; neuroendocrine and autonomic nervous systems; psychiatry and mental health; methods and techniques. Perhaps because our paper was mathematically, physically, biologically (neuroscientifically), and phenomenologically motivated from the start? Nevertheless, venturing in novel, fresh, testable proposals is badly needed in contemporary neuroscience, so to break into “the utter darkness of the inner mechanism of psychic acts… during the production of the concomitant phenomena of perception and thought, namely, feelings, consciousness and volition”—as Cajal had already observed in his opus magnus ‘Textura’. But as he soberly confessed: “This ideal is still very distant” (Ramon y Cajal, 1899-1904, p. 1,141). In the pursuit of that very ideal, neuroscience and psychology have had, and continue to have, a plethora of movements and schools of thought: behaviorism, cognitivism, neural Darwinism, social constructivism, Bayesian optimization...In our paper, we propose to go a step further, via the notion of topodynamics, towards “projectionism.” In what follows, trying to elucidate the main features of this Emperor’s new clothing, we proceed with the responses to the comments received.

Physical and biological measurements might display range values extending towards infinite. The occurrence of infinity in equations, such as the black hole singularities, is a troublesome issue that causes many theories to break down when assessing extreme events. Different methods, such as re-normalization, have been proposed to avoid detrimental infinity. Here a novel technique is proposed, based on geometrical considerations and the Alexander Horned sphere, that permits to undermine infinity in physical and biophysical equations. In this unconventional approach, a continuous (...) monodimensional line becomes an assembly of countless bidimensional lines that superimpose in quantifiable knots and bifurcations. In other words, we may state that Achilles leaves the straight line and overtakes the turtle. (shrink)

Neuroscientists are able to detect physical changes in information entropy in the available neurodata. However, the information paradigm is inadequate to describe fully nervous dynamics and mental activities such as perception. This paper suggests explanations to neural dynamics that provide an alternative to thermodynamic and information accounts. We recall the Banach–Tarski paradox, which informally states that when pieces of a ball are moved and rotated without changing their shape, a synergy between two balls of the same volume is achieved instead (...) of the original one. We show how and why BTP might display this physical and biological synergy meaningfully, making it possible to model nervous activities. The anatomical and functional structure of the central nervous system’s nodes and edges makes it possible to perform a sequence of moves inside the connectome that doubles the amount of available cortical oscillations. In particular, a BTP-based mechanism permits scale-invariant nervous oscillations to amplify and propagate towards widely separated brain areas. Paraphrasing the BTP’s definition, we could state that: when a few components of a self-similar nervous oscillation are moved and rotated throughout the cortical connectome, two self-similar oscillations are achieved instead of the original one. Furthermore, based on topological structures, we illustrate how, counterintuitively, the amplification of scale-free oscillations does not require information transfer. (shrink)

Whys and Ways of Science presents the issues, arguments and the theories that have attracted the greatest attention and which are covered in the greater majority of tertiary courses offered in philosophical and social studies of science. A primary aim of the book is to present a suitably broad picture of the spectrum of theories about science without sacrificing too much detail. About one-half of the book is devoted to the most influential philosophical theories of science and scientific change to (...) emerge post-World War Two in Western countries, in particular the holistic theories of Thomas Kuhn, Imre Lakatos and Larry Laudan. The second half deals with socially-oriented theories of science such as Functionalist sociology of science; the Strong Programme in the Sociology of Scientific Knowledge; the Interests analysis of science, the theories of Paul Feyerabend and of Bruno Latour. The final chapter examines the question of whether the rationality of science can be sustained in the face of growing accounts of science as a purely social activity and presents an original model for theory choice in science.

There is growing evidence that some individuals engage in both self-harm and aggression during the course of their lifetime. The co-occurrence of self-harm and aggression is termed dual-harm. Individuals who engage in dual-harm may represent a high-risk group with unique characteristics and pattern of harmful behaviours. Nevertheless, there is an absence of clinical guidelines for the treatment and prevention of dual-harm and a lack of agreed theoretical framework that accounts for why people may engage in this behaviour. The present work (...) aimed to address this gap in the literature by providing a narrative review of previous research of self-harm, aggression and dual-harm, and through doing so, presenting an evidence-based theory of dual-harm – the cognitive-emotional model of dual-harm. This model draws from previous studies and theories, including the General Aggression Model, diathesis-stress models and emotional dysregulation theories. The cognitive-emotional model highlights the potential distal, proximal and feedback processes of dual-harm, the role of personality style and the possible emotional regulation and interpersonal functions of this behaviour. In line with our theory, various clinical and research implications for dual-harm are suggested, including hypotheses to be tested by future studies. (shrink)

The brain, rather than being homogeneous, displays an almost infinite topological genus, since it is punctured with a high number of “cavities”. We might think to the brain as a sponge equipped with countless, uniformly placed, holes. Here we show how these holes, termed topological vortexes, stand for nesting, non-concentric brain signal cycles resulting from the activity of inhibitory neurons. Such inhibitory spike activity is inversely correlated with its counterpart, i.e., the excitatory spike activity propagating throughout the whole brain tissue. (...) We illustrate how Pascal’s triangles and linear and nonlinear arithmetic octahedrons are capable of describing the three-dimensional random walks generated by the inhbitory/excitatory activity of the nervous tissue. In case of nonlinear 3D paths, the trajectories of excitatory spiking oscillations can be depicted as the operation of filling the numbers of octahedrons in the form of “islands of numbers”: this leads to excitatory neuronal assemblies, spaced out by empty areas of inhibitory neuronal assemblies. These mathematical procedures allow us to describe the topology of a brain of infinite genus, to represent inhibitory neurons in terms of Betti numbers and to highlight how spike diffusion in neural tissues is generated by the random activation of tiny groups of excitatory neurons. Our approach suggests the existence of a strong mathematical background subtending the intricate oscillatory activity of the central nervous system. (shrink)

The Causal Theory of Quantum Mechanics provides a better understanding of the fundamentals of quantum mechanics than is provided by Orthodox (i.e. Copenhagen) Quantum Theory by describing micro-phenomena in terms of entities and processes in space and time, thereby embracing causality at the quantum level. The book focuses especially on finding solutions to conceptual issues about the nature of energy, the conservation of energy, forces, and the Exclusion Principle within the context of the Causal Theory of Quantum Mechanics.

Yet these volumes also indicate that religious ethics should pay more attention to particular sins. (shrink)

Letter to the Editors in response to Alasdair Richmond's 'Time Travelers'.

The perplexing nature of time has been more contemplated, speculated, written, and debated about over the ages than virtually any other subject, with the possible exception of religion. Yet time seems more elusive than the vast majority of other metaphysical concepts. Time remains mysterious, for we lack an understanding of time at a basic physical level. Concepts of time in theories of modern physics and time as found in contemporary western analytic philosophy are discussed.

Most people would probably agree that the obvious feature about time is that it progresses (or flows). However, our everyday experience of the apparent ‘dynamic’ nature of time conflicts with the basic laws of physics which do not posit any passage of time. This clash between experience and fundamental physics has led a few physicists to develop theories of the universe in which time’s passage is an explicit feature. Two such theories are discussed along with a possible non-‘dynamic’ alternative.

Most arguments against the possibility of time travel use the same old, familiar objection: If I could travel back in time, then I could kill my earlier (i.e. younger) self. Since I do exist such an action would result in a contradiction. Therefore time travel is impossible. This is a statement of the Principal Paradox of Time Travel. Some philosophers have argued that such actions as attempting to kill one’s earlier self would always fail and that there is nothing especially (...) strange about such failures. Despite these arguments, the problem generally is not viewed as being solved in favour of time travel. The above objection to time travel is also used to dismiss a particular class of cosmological models as being unphysical. This paper provides a solution to the Principal Paradox by exploring both the logical and causal implications of time travel. (shrink)
