Dogs display vast phenotypic diversity, including differences in height, skull shape, tail, etc. Yet, humans are almost always able to quickly recognize a dog, despite no single feature or group of features are critical to distinguish dogs from other objects/animals. In search of the mental activities leading human individuals to state “I see a dog”, we hypothesize that the brain might extract meaningful information from the environment using Ramsey sentences-like procedures. To turn the proposition “I see a dog” in a (...) Ramsey sentence, the term dog must be replaced by a long and complex assertion consisting only of observational terms, existential quantifiers and operational rules. The Ramsey sentence for “I see a dog” sounds: “There is at least an entity called dog which satisfies the following conditions: it is an animal, it has four legs, …, etc, …, and is something that I have in my sight”. We discuss the biological plausibility and the putative neural correlates of a Ramsey-like mechanism in the central nervous system. We accomplish a brain-inspired, theoretical neural architecture consisting of a parallel network that requires virtually no memory, is devoid of probabilistic choices and can analyze huge but finite amounts of unique visual details, combining them into a single conceptual output. In sum, Ramsey sentence stands for a versatile tool that can be used not just as a methodological device to cope with biophysical affairs, but also for a model to describe the real functioning of cognitive operations such as sensation and perception.

The compulsive habit model proposed by Everitt and Robbins has accumulated important empirical evidence. One of their proposals is the existence of an axis, on which each a person with a particular addiction can be located depending on the evolutionary moment of his/her addictive process. The objective of the present study is to contribute in addressing the identification of such axis, as few studies related to it have been published to date. To do so, the use/abuse of Information and Communication (...) Technologies (ICT) was quantified on an initial sample of 807 subjects. Questionnaires were also delivered to measure impulsivity, compulsivity and symptoms of prefrontal dysfunction. Evidence of the existence of the proposed axis was obtained by means of Machine Learning techniques, thus allowing the classification of each subject along the continuum. The present study provides preliminary evidence of the existence of the Impulsivity-Compulsivity axis, as well as an IT tool so that each patient that starts getting treatment for an addiction can be statistically classified as “impulsive” or “compulsive.” This would allow the matching of each person with the most appropriate treatment depending on his/her moment in the addiction/abuse process, thus facilitating the individualized design of each therapeutic process and a possible improvement of the results of the treatment.

The intention and the result of a scientific inquiry is to obtain an understanding and a control of some part of the universe. This statement implies a dualistic attitude on the part of scientists. Indeed, science does and should proceed from this dualistic basis. But even though the scientist behaves dualistically, his dualism is operational and does not necessarily imply strict dualistic metaphysics.

In a recent essay Professor Taylor criticizes the criteria used by Rosenblueth, Wiener and Bigelow in 1943 to distinguish purposeful from non-purposeful behavior. He also criticizes our definition of behavior, our concept of the vague as opposed to the general, our use of the word correlation, and our statement that a system may reach a final condition. Indeed, there seems to be little, if anything, in our paper to which he does not emphatically object.He maintains that the notions of purpose (...) and teleology are not only useless for the understanding of mechanical behavior, but wholly incongruous when applied to this behavior. He further affirms that our use of the term purpose “bears no similarity whatever to the meaning which is ordinarily attached to it.” He does not state, however, his own notions of purpose and teleology; and the meaning which he considers to be ordinarily attached to the term purpose. This omission weakens his criticism considerably. (shrink)

This article aims to offer an overview of the problem of suicide in Augustine of Hippo, from the anti-Manichean texts of the late 380s CE to De ciuitate dei and the rejoinder to Gaudentium (Contra Gaudentium). A transversal analysis of the evolution of the concept of voluntary death throughout the work of Augustine allows us to identify up to four different conceptions of suicide, each of them corresponding to a rather well-defined chronological period: a philosophical conception, that we find in (...) De libero arbitrio; a moral one, that we can excerpt from De mendacio; a polemical approach in the context of controversy against Donatism, which we can retrace in a set of writings from 400 to 412 CE, and especially in Contra epistulam Parmeniani; and, finally, the conception of suicide as homicide, that appears in De ciuitate dei and that will define the decisive and most widespread doctrine of Augustine in this matter. In this way, this paper aims to enrich, from a transversal and chronological perspective, the studies that have been carried out over the last decades on suicide in Augustine. (shrink)

Spontaneous brain activity has received increasing attention as demonstrated by the exponential rise in the number of published papers on this topic over the last thirty years. Such “intrinsic” brain activity, generated in the absence of an explicit task, is frequently associated with resting-state or default-mode networks. The focus on characterizing spontaneous brain activity promises to shed new light on questions concerning the structural and functional architecture of the brain and how they are related to “mind”. However, many critical questions (...) have yet to be addressed. In this review, we focus on a scarcely explored area, specifically the energetic requirements and constraints of spontaneous activity, taking into account both thermodynamical and informational perspectives. We argue that the “classical” definitions of spontaneous activity do not take into account an important feature, that is, the critical thermodynamic energetic differences between spontaneous and evoked brain activity. Spontaneous brain activity is associated with slower oscillations compared with evoked, task-related activity, hence it exhibits lower levels of enthalpy and “free-energy” (i.e. the energy that can be converted to do work), thus supporting noteworthy thermodynamic energetic differences between spontaneous and evoked brain activity. Increased spike frequency during evoked activity has a significant metabolic cost, consequently, brain functions traditionally associated with spontaneous activity, such as mind wandering, require less energy that other nervous activities. We also review recent empirical observations in neuroscience, in order to capture how spontaneous brain dynamics and mental function can be embedded in a non-linear dynamical framework, which considers nervous activity in terms of phase spaces, particle trajectories, random walks, attractors and/or paths at the edge of the chaos. This takes us from the thermodynamic free-energy, to the realm of “variational free-energy”, a theoretical construct pertaining to probability and information theory which allows explanation of unexplored features of spontaneous brain activity.

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)

Interest in the intersection between bilingualism and cognitive control and accessibility to neuroimaging methods have resulted in numerous studies with a variety of interpretations of the bilingual cognitive advantage. Neurocomputational Emergentism (or Neuroemergentism for short) is a new framework for understanding this relationship between bilingualism and cognitive control. This framework considers Emergence, in which two small elements are recombined in an interactive manner, yielding a non-linear effect. Added to this is the notion that Emergence can be captured in neural systems (...) using computationally inspired models. This review poses that bilingualism and cognitive control, as examined through the Neuroemergentist framework, are interwoven through development and involve the non-linear growth of cognitive processing encompassing brain areas that combine and recombine, in symbiotic and parasitic ways, in order to handle more complex types of processing. The models that have sought to explain the neural substrates of bilingual cognitive differences will be discussed with a reinterpretation of the entire bilingual cognitive advantage within a Neuroemergentist framework incorporating its neural bases. It will conclude by discussing how this new Neuroemergentist approach alters our view of the effects of language experience on cognitive control. Avenues to move beyond the simple notion of a bilingual advantage or lack thereof will be proposed. (shrink)

Schelling and music.- Music is a theme which enables us to have more direct access to the philosophy of Schelling. This is because in the Romantic period it is typical to find the conceptual framework provided by affirming a unity between reason and sensibility, while thought of the modern period tends to split these two. Here music is dealt with on the basis of a study of the meaning of art in the System of transcendental idealism, and of the question (...) of philosophy as a system of identity. (shrink)

The contribution describes some aspects related to the representation of special curves; recalling mechanisms created specifically for the design of these curves, which have particular characteristics. Through the construction of a simple apparatus, consisting of two pendulums—which oscillate at the same time- it is possible to graphically reproduce Lissajous’ experiments on the commuting vibrations of the diapasons. This equipment was first built by Samuel Charles Tisley (London 1829-Unknown), under the name of harmonographer. The contribution aslo illustrates the essential characteristics of (...) the harmonograph—born as a means of analysing vibrations—but which, by its principle belongs to mechanics, for its applications to acoustic science and geometry for the ability to draw “harmonious” curves.

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.

This essay has two goals. The first is to define the behavioristic study of natural events and to classify behavior. The second is to stress the importance of the concept of purpose.Given any object, relatively abstracted from its surroundings for study, the behavioristic approach consists in the examination of the output of the object and of the relations of this output to the input. By output is meant any change produced in the surroundings by the object. By input, conversely, is (...) meant any event external to the object that modifies this object in any manner. (shrink)

As is well known, A. C. Haddon visited Torres Straits for the first time in the\nsummer of 1888 with the purpose of studying, as a marine biologist, the fauna\nand the structure and mode of formation of the coral reefs in Torres Straits. There\nbegan Haddon’s ’conversion’ from zoology to anthropology.’ It seems that\nHaddon felt an urgent need to collect ethnographic information on the islanders\nbecause he saw they were changing and diminishing in number very quickly, and\ntherefore their customs were vanishing.\nVery soon after (...) my arrival in the Straits I found that the natives of the\nislands had of late years been greatly reduced in number, and that, with the\nexception of but one or two individuals, none of the white residents knew\nanything about the customs of the natives, and not a single person cared\nabout them personally. When I began to question the natives I discovered\nthat the young men had a very imperfect acquaintance with the old habits\nand beliefs, and that only from the older men was reliable information to be\nobtained. So it was made clear to me that if I neglected to avail myself of the\npresent opportunity of collecting information on the ethnography of the\nislanders, it was extremely probable that that knowledge would never be\ngleaned - for if no one interested himself in the matter meanwhile, it was\nalmost certain that no trustworthy information could be collected in, say, ten years’ time. This being my opinion, I felt it my duty to fill up all the\ntime not actually employed in my zoological researches in anthropological\nstudies. (shrink)

Original, or 'old', institutional economics (OIE) – also known as 'institutionalism' – played a key role in its early stages; it could be said that it was once the 'mainstream economics' of the time. This period ran approximately from the first important contributions of Thorstein Veblen in 1898 to the implementation of the New Deal in the early 1930s, where many institutionalists played a significant role. However, notwithstanding its promising scientific and institutional affirmation, institutional economics underwent a period of marked (...) decline that spanned from the mid-1930s to the late 1980s, when a new season for institutional economics was set in motion. In order to cast some light on this complex issue – without any claim of completeness – we have organised the work as follows: in the first section we consider the main interpretations of this phenomenon. In the subsequent sections we analyse a number of 'endogenous' aspects which might have played a significant role in the period of decline: (i) the relations of institutional economics with Keynes's macroeconomic theory; (ii) the links between theoretical and empirical analysis and the supposed lack of a clear theory; (iii) the interdisciplinary orientation.

La polarización, los populismos y la posverdad forman tres fenómenos sociopolíticos fundamentales para comprender cómo se está orientando la política en los sistemas demoliberales. La polarización política se suele entender como un proceso dinámico de activación de las divisiones entre dos o más grupos sociales en el transcurso de los debates públicos que puede terminar con una ruptura comunicativa o una comunicación fallida. Si bien los especialistas no coinciden a la hora de definir el populismo, se puede comprender como una (...) forma concreta de construir el pueblo mediante un discurso que contrapone este al anti-pueblo. La posverdad se referiría a una tendencia cultural donde las verdades de hecho sufren una merma en favor de las verdades vivenciadas subjetivamente. Estos fenómenos tienden a ser percibidos por una buena parte de la sociedad y del mundo académico como una amenaza grave para las bases pluralistas y reflexivas de la democracia. Sin embargo, esa consideración está decantada normativamente. Este artículo trata de explorar un marco referencial diferente, el emotivismo, y cómo, desde este ángulo, toman sentido los tres conceptos clave: polarización, populismo y posverdad. (shrink)

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)

This paper examines how international law contributes to contemporary understandings of transitional justice with respect to reparations for victims of gross and systematic human rights abuses. The author surveys the jurisprudence of the Inter-American Court of Human Rights through 2003 to determine how the Court’s practice can be used to guide the formulation of reparatory policies during political transition. Recognizing that the direct application of Inter-American case law to situations of mass atrocity is not always viable in practice, the author (...) analyzes regional human rights jurisprudence, particularly that relating to compensation, to determine what role the Court’s rules can and cannot play as a reference for policymakers and societies faced with the challenge of designing a reparations program. He concludes that while landmark Court decisions like Velásquez Rodríguez provide general normative guidance, there are significant obstacles to extending to the transitional justice context many of the measures, amounts, and formulas relied upon by the Court in awarding compensation. The fairness of compensation outside the courtroom cannot be determined with reference to predetermined rules, but depends on the factual context in which the measures are adopted including the number of victims involved. A better source of comparative inspiration is found in the Court’s growing practice of adopting non-monetary reparations measures to deal with moral harm. (shrink)
