Gil R, Arroyo-Anllo EM, Ingrand P, Gil M, Neau JP, Ornon C, Bonnaud V. Self-consciousness and Alzheimer’s disease. Acta Neurol Scand 2001: 104: 296–300. # Munksgaard 2001. Objectives – To propose a neuropsychological study of the various aspects of self-consciousness (SC) in Alzheimer’s disease. Methods – Forty-five patients with probable mild or moderate AD were included in the study. Severity of their dementia was assessed by the Mini Mental State (MMS). Fourteen questions were prepared to evaluate SC. Results – No (...) significant correlations were found between SC score and educational level, age, and duration of disease. A significant correlation was found between SC score and the severity of dementia, whereas frontal disturbances were just short of the significance threshold. The various aspects of SC were not impaired to the same degree. The most disturbed ones were awareness of cognitive deficiencies, moral judgements and prospective memory. The least disturbed aspects were awareness of identity and of mental representation of the body. Items relating to anosognosia and moral judgements were significantly correlated with the MMS score, whereas affective state, body representation disorders, prospective memory, and capacities for introspection were not related to the severity of the dementia. Consciousness of identity was sound, regardless of MMS score. Conclusions – AD clearly induces an heterogeneous impairment of SC. SC requires a convergence of many neural networks. In AD, neuronal alterations involve many cortical areas and information sent to the associative frontal cortex from memory, language and visuospatial areas is lacking or disturbed. Thus, the sequential order of successive stimuli cannot be maintained by the heteromodal associative cortex (dorsal convexity of the prefrontal cortex), and the supramodal associative cortex (located rostrally in the frontal lobes) is unable to provide reliable monitoring and assessment of simultaneous neural cognitive networks carrying insufficient and inadequate input. The core deficiency in AD patients might be impaired SC equated with the disability to maintain sequential and simultaneous ‘‘attention to life’’. The Self-Consciousness Questionnaire, a clinical scale providing multidimensional measurement, indicates that different aspects of consciousness are not correlated with overall cognitive deficiency as determined by the MMSE.

A major intervention that marks the first appearance of Gil's work in English, Metamorphoses of the Body gives us an entirely new way of looking at relationships between bodies, forces, politics, and people.
Łukasiewicz’s infinite-valued logic is commonly defined as the set of formulas that take the value 1 under all evaluations in the Łukasiewicz algebra on the unit real interval. In the literature a deductive system axiomatized in a Hilbert style was associated to it, and was later shown to be semantically defined from Łukasiewicz algebra by using a “truth-preserving” scheme. This deductive system is algebraizable, non-selfextensional and does not satisfy the deduction theorem. In addition, there exists no Gentzen calculus fully adequate (...) for it. Another presentation of the same deductive system can be obtained from a substructural Gentzen calculus. In this paper we use the framework of abstract algebraic logic to study a different deductive system which uses the aforementioned algebra under a scheme of “preservation of degrees of truth”. We characterize the resulting deductive system in a natural way by using the lattice filters of Wajsberg algebras, and also by using a structural Gentzen calculus, which is shown to be fully adequate for it. This logic is an interesting example for the general theory: it is selfextensional, non-protoalgebraic, and satisfies a “graded” deduction theorem. Moreover, the Gentzen system is algebraizable. The first deductive system mentioned turns out to be the extension of the second by the rule of Modus Ponens. (shrink)
The objective of this paper is analyzing to which extent the multiverse hypothesis provides a real explanation of the peculiarities of the laws and constants in our universe. First we argue in favor of the thesis that all multiverses except Tegmark’s “mathematical multiverse” are too small to explain the fine tuning, so that they merely shift the problem up one level. But the “mathematical multiverse" is surely too large. To prove this assessment, we have performed a number of experiments with (...) cellular automata of complex behavior, which can be considered as universes in the mathematical multiverse. The analogy between what happens in some automata (in particular Conway’s “Game of Life") and the real world is very strong. But if the results of our experiments can be extrapolated to our universe, we should expect to inhabit—in the context of the multiverse—a world in which at least some of the laws and constants of nature should show a certain time dependence. Actually, the probability of our existence in a world such as ours would be mathematically equal to zero. In consequence, the results presented in this paper can be considered as an inkling that the hypothesis of the multiverse, whatever its type, does not offer an adequate explanation for the peculiarities of the physical laws in our world.

Impairment of the Self has been described in frontal–temporal dementia but little research has been carried out in patients with Alzheimer’s disease .ObjectiveThe aim of this study was to explore changes in the self in patients with AD.MethodForty-seven patients with mild to moderate AD were examined using a semi-structured scale designed to assess the self-concept along three dimensions, namely, the Material Self, the Social Self and the Spiritual Self.ResultsThe majority of patients presented impairment of at least one dimension of the (...) Self. When only one dimension was affected, it was always the Social Self. The severity of impairment of the Self was correlated to the impairment of the semantic autobiographical memory and apathy.ConclusionThe Self is impaired in AD and the Social Self dimension appears to be more vulnerable in AD than other dimensions.

This landmark work will make a genuine contribution to the theory and practice of reparations.
In this paper we show that, in Gentzen systems, there is a close relation between two of the main characters in algebraic logic and proof theory respectively: protoalgebraicity and the cut rule. We give certain conditions under which a Gentzen system is protoalgebraic if and only if it possesses the cut rule. To obtain this equivalence, we limit our discussion to what we call regular sequent calculi, which are those comprising some of the structural rules and some logical rules, in (...) a sense we make precise. We note that this restricted set of rules includes all the usual rules in the literature. We also stress the difference between the case of two-sided sequents and the case of many-sided sequents, in which more conditions are needed. (shrink)
Espero defender la tesis de que la lingüística contemporánea se ha ido consolidando como una ciencia estable. Para ello analizaré, en los conocidos términos de Hempel, casos concretos de explicaciones nomológico-deductivas y probabilístico-inductivas brindadas por la teo-ría generativa y por la teoría sistémico-funcional. Estas explicaciones so-bre hechos del lenguaje son muy superiores a las “no-científicas” : Se sostienen en leyes universales y probabilísticas, cumplen con los requi-sitos de contrastabilidad y pertinencia explicativa y, fundamentalmente, sirven para establecer o comprender las predicciones. (...) Finalmente, el problema de la incompatibilidad manifiesta entre los supuestos de una teoría “biologista” y los de una teoría “sociológica” , puede interpretarse en función de la vieja idea de que en la ciencia no hay experimentos cruciales.In this paper I shall argue that contemporary linguistics has developed as a stable science. I will use Hempel’s well known concep-tual apparatus in my analysis, and apply it to concrete examples of no-mologic-deductive and probabilistic-inductive explanations provided both by the generative and the systemic-functional theory. The expla-nations of concrete linguistic facts yielded by these theories are much better than “non-scientific” explanations : they are based on universal and probabilistic laws, they satisfy the requirements of contrastability and explicative relevance and, more importantly, they are useful in es-tablishing or understanding predictions. Finally, the manifest incom-patibility between the assumptions of a “biologist” theory and those of a “sociologic” theory can be analyzed in terms of the old idea that there are no crucial experiments in science.

Perhaps the most remarkable feature about this book is the effort made by its author in order to shed light on the most intriguing question that surrounds disgust: how is it possible for disgust to be so flexible with its objects? This book is highly recommended for those readers interested in the latest and most exciting aspects of current scholarship on the study of the emotions. Readers too who are interested on evolutionary psychology, moral psychology or neuroethics will find this (...) book stimulating. However, it should be noted that perhaps it may not be liked for readers allergic to evolutionary approaches and the vocabulary of cognitive science. (shrink)
In order to improve the management of copyright in the Internet, known as Digital Rights Management, there is the need for a shared language for copyright representation. Current approaches are based on purely syntactic solutions, i.e. a grammar that defines a rights expression language. These languages are difficult to put into practise due to the lack of explicit semantics that facilitate its implementation. Moreover, they are simple from the legal point of view because they are intended just to model the (...) usage licenses granted by content providers to end-users. Thus, they ignore the copyright framework that lies behind and the whole value chain from creators to end-users. Our proposal is to use a semantic approach based on semantic web ontologies. We detail the development of a copyright ontology in order to put this approach into practice. It models the copyright core concepts for creation, rights and the basic kinds of actions that operate on content. Altogether, it allows building a copyright framework for the complete value chain. The set of actions operating on content are our smaller building blocks in order to cope with the complexity of copyright value chains and statements and, at the same time, guarantee a high level of interoperability and evolvability. The resulting copyright modelling framework is flexible and complete enough to model many copyright scenarios, not just those related to the economic exploitation of content. The ontology also includes moral rights, so it is possible to model this kind of situations as it is shown in the included example model for a withdrawal scenario. Finally, the ontology design and the selection of tools result in a straightforward implementation. Description Logic reasoners are used for license checking and retrieval. Rights are modelled as classes of actions, action patterns are modelled also as classes and the same is done for concrete actions. Then, to check if some right or license grants an action is reduced to check for class subsumption, which is a direct functionality of these reasoners. (shrink)
Este artículo analiza la concepción de la intencionalidad colectiva de John Searle. Primero, enmarca dicho concepto en el conjunto de la ontología social del autor, y expone algunos puntos clave de su teoría de la intencionalidad. Segundo, presenta el modo en que Searle concibe la intencionalidad colectiva y el modo en que compatibiliza dicha idea con el individualismo metodológico y con el internalismo mental. Por último, explica las principales insuficiencias de la propuesta de Searle y la incoherencia existente entre los (...) propósitos generales del autor y su tratamiento de la intencionalidad colectiva.

El propósito de este ensayo es explorar la doctrina política de Platón sobre la democracia a partir del concepto sinergia, es decir, de poder sinérgico, colaboración creativa que reduce los grados de dominación en el régimen político, tal como lo entiende James Craig. Aunque el concepto de poder sinérgico no fue conocido por Platón y ha sido descuidado tanto por la politología como por la filosofía política, considero que es el criterio indispensable para dejar en claro muchas de las ambigüedades (...) del pensamiento platónico. Partimos de la paradójica premisa que Platón pretende crear un autoritarismo absoluto sin dominación. En el desarrollo, se hará evidente que el pensamiento político de Platón está condicionado por unos supuestos que le obligan a aceptar un utopismo irrealizable. Entre esos supuestos destaca la Falacia Angélica, tal como la expone Mortimer Adler. También supone una concepción absolutista de la libertad positiva, así como que la libertad moral atrapada en un estado estancado. La conclusión se resume en un cuadro comparativo entre las características de la utopía platónica y el ideal sinérgico. Destaca en dicho cuadro como Platón toma partido por el autoritarismo virtuoso que condena la transformación política al reino de lo imaginario, en vez de tomar partido por las formas de gobierno compartido. Esto ha dado como resultado histórico la tentación totalitaria de pensar que hay algo mejor que la democracia. Palabras Clave : Platón; política; democracia; sinergia; libertad moral; libertad positiva; falacia angélica. Plato against democracy or the misfortunes of synergyThe purpose of this essay is to explore Plato’s political doctrine on democracy in the light of the concept of synergy, that is to say, of synergic power, which is a creative cooperation that lowers the degrees of domination within the political regime, as is understood by James Craig. Although the concept of synergic power was not known by Plato, and has been neglected by both political science and political philosophy, I consider it to be the indispensable criterion to clarify many ambiguities of Platonic thought. We start from the paradoxical premise that Plato intends to create an absolute authoritarianism without domination. As we progress it will become evident that Plato’s political thought is conditioned by assumptions that make him accept an unfeasible utopianism. Among those assumptions there stands out the Angelical Fallacy, as is exposed by Mortimer Adler. It also implies an absolutistic conception of positive freedom, as well as the idea that moral freedom is trapped in a stagnant state. The conclusion is summed up in a chart comparing the characteristics of Platonic utopia and synergic ideal. In that chart there stands out how Plato takes sides for virtuous authoritarianism, which dooms political transformation to the realm of the imaginary, instead of taking sides for the forms of shared government. This has brought as a historical result the totalitarian temptation of thinking that there might be something better than democracy. Keywords : Plato; Politics; Democracy; Synergy; Moral Freedom; Positive Freedom; Angelical Fallacy. (shrink)
En el siguiente estudio examinaremos el sentimiento de vergüenza desde dos planteamientos distintos formulados por Aristóteles: el de la Retórica, por una parte, y el de la Ética Nicomáquea , por otra, con la finalidad de dar cuenta de las diferencias, así como de los puntos de confluencia que existen entre ambos. Asimismo, consideraremos la intrincada conexión que existe entre la agencia humana y cuestiones tales como la voluntariedad, la responsabilidad y la culpa, así como el papel fundamental de esta (...) emoción en las relaciones interpersonales.

When considering m-sequents, it is always possible to obtain an m-sequent calculus VL for every m-valued logic (defined from an arbitrary finite algebra L of cardinality m) following for instance the works of the Vienna Group for Multiple-valued Logics. The Gentzen relations associated with the calculi VL are always finitely equivalential but might not be algebraizable. In this paper we associate an algebraizable 2-Gentzen relation with every sequent calculus VL in a uniform way, provided the original algebra L has a (...) reduct that is a distributive lattice or a pseudocomplemented distributive lattice. We also show that the sentential logic naturally associated with the provable sequents of this algebraizable Gentzen relation is the logic that preserves degrees of truth with respect to the original algebra (in contrast with the more common logic that merely preserves truth). Finally, for some particular logics we obtain 2-sequent calculi that axiomatize the algebraizable Gentzen relations obtained so far. (shrink)
There are many open questions concerning relationships between social subjects and armed actors in a context of prolonged violence. The collective actors and the role of autonomous actions are at issue. This situation is even more complex if we focus on a segment of the population: Colombian women, historically, have been excluded and victimized by the war in many ways. Exploring the framework of forced migration in Colombia, this paper analyzes claims made about recognition and inclusion and examines the political (...) strategies that emergent actors are attempting to implement. Women in a war context have developed holistic and empowered ways of resistance to create a space where self-determination is possible. Beyond the struggle for sheer survival, the everyday experience of conflict, interactions among diverse actors and the practices of the resistance show that women have an active role in mobilization and self-organization instead of being merely co-opted or submitted by the armed actors.

This work is devoted to clear how the foundation of modern thought takes place as a reinforced reiteration of metaphysics which is provoked by a defensive fold of reason against the assault of transrational. We begin showing the way this asault is experimented by Descartes in a decisive moment of his life and how reagently replies to him. The article continues showing how physics and metaphysics are being moved in Descartes on the wake of a try to build seawalls against (...) the incessant return of what has been repressed. (shrink)
A couple of decades ago natural phenomena began to be approached from a comprehensive and transdisciplinary point of view, as it was understood that living beings and their environments are not linear but complex. There is no doubt that this perspective of visualizing complexity and working inter-and transdisciplinarily has to be applied. The reflection on the theoretical observation (i.e. meta-observation) involved in the concept of poly-contexturality is the framework in which a theory of complex systems is possible, which in turn (...) enables an observation that oscillates (a concept of chaos theory) between modelsstructured in a hierarchical order (normally linked to a logical-deductive formalization) and models structured in hetero‐hierarchy. And this would allow this reflection to be done in a formalized language that does not follow either the principles of the Aristotelian logic or the postulates of the Kantian transcendental reflection. It is precisely this liberation from the dictates of mono-contextural logic what paves the way to an observation of complexity, in which one or the other language is used to model the states of things, such as the epistemological problems of molecular biology or the social systems. And-what is gaining relevance-it also paves the way to a true transdisciplinary meta-observation, since each discipline chooses its own contexture and only the use of poly-contexturality makesit possible to formulate transdisciplinary relationships within the framework of such meta-logic.

Es indudable que el inconsciente colectivo estudiado por Jung y su escuela psicoanalítica, nos ha demostrado fehacientemente que las conductas observadas y aprendidas en la infancia tanto en la familia como en la sociedad, se reproducen de manera muy similar en las generaciones jóvenes.
La teoría generativa y la teoría sistémico-funcional pueden concebirse como teorías científicas: Han confirmado hipótesis, proveen explicaciones y, a partir de estas últimas, efectúan predicciones. Sin embargo, ambas teorías manejan supuestos incompatibles sobre el mismo objeto: el lenguaje. Después de analizar el problema de las confirmaciones y las explicaciones en lingüística, se intentará demostrar que esa incompatibilidad puede resolverse mediante un “principio de complementariedad”: El lenguaje es, al mismo tiempo, una “facultad de la mente” y un “producto de la cultura”, (...) aunque los dos aspectos no puedan captarse en el ámbito de una sola teoría.Palabras llave: Lingüística; incompatibilidad; mente; cultura; complementariedad.Generative and systemic-functional theories may be conceived as scientific theories: they have confirmed hypotheses, they provide explanations, and based on these explanations, they make predictions. Nevertheless, both theories use incompatible assumptions about the same object: language.
