An algebraic interpretation of multigraph networks is introduced in relation to conscious experience, brain and body. These multigraphs have the ability to merge by an associative binary operator \(\odot \), accounting for biological composition. We also study a mathematical formulation of splitting layers, resulting in a formal analysis of the transition from conscious to non-conscious activity. From this construction, we recover core structures for conscious experience, dynamical content and causal constraints that conscious interactions may impose. An important result is the (...) prediction of structural topological changes after conscious interactions. These results may inspire further use of formal mathematics to describe and predict new features of conscious experience while aligning well with formal tries to mathematize phenomenology, phenomenological tradition and applications to artificial consciousness.

El artículo expone la evolución de las expectativas acerca del futuro y destino final del hombre tanto a nivel individual como colectivo. Hasta el siglo XVIII predominaban las preocupaciones referidas al destino personal de cada hombre y el significado de la muerte. Tras las revoluciones que acabaron con el antiguo régimen, empezó a dominar el interés por el futuro de la humanidad en su conjunto. Desde mediados del siglo XX hay una preocupación creciente ante el peligro de que la especie (...) humana desaparezca y sea suplantada por otro tipo de entidades, tal vez desarrolladas por el propio hombre. El transhumanismo se ha presentado como una respuesta, basada en la ciencia, a las ansias de supervivencia y mejora del hombre. No obstante, sus propuestas adolecen de varias debilidades, algunas de ellas posiblemente irreparables. (shrink)

Traditional geometry concerns itself with planimetric and stereometric considerations, which are at the root of the division between plane and solid geometry. To raise the issue of the relation between these two areas brings with it a host of different problems that pertain to mathematical practice, epistemology, semantics, ontology, methodology, and logic. In addition, issues of psychology and pedagogy are also important here. To our knowledge there is no single contribution that studies in detail even one of the aforementioned areas.

We study the theory of a Hilbert space H as a module for a unital C*-algebra ${\mathcal{A}}$ from the point of view of continuous logic. We give an explicit axiomatization for this theory and describe the structure of all the representations which are elementary equivalent to it. Also, we show that this theory has quantifier elimination and we characterize the model companion of the incomplete theory of all non-degenerate representations of ${\mathcal{A}}$ . Finally, we show that there is an homeomorphism (...) between the space of types of norm less than 1 in this model companion, and the space of quasistates of the C*-algebra ${\mathcal{A}}$. (shrink)

In the Third Antinomy Kant exposes in a dramatically way the conflict between freedom and natural necessity. Kant uses denominations that they induce to confusion, because he resolves different problems than those we use to attribute to him. According to Kant, the new science opposes natural legality and freedom. This paper maintains that this false interpretation of the scientific epistemology depends on a slanted vision originated in the rationalistic metaphysics; among others reasons, because Kant takes the Physics from Wolff instead (...) of Newton.

Atherosclerosis is the major cause of death in the industrialised world. Though much work on the pathogenesis of atherosclerosis points to 'oxidised' low density lipoprotein (LDL) as a key aetiological feature in the generation of the atherosclerotic plaque, the nature of this 'oxidised' LDL in vivo remains an enigma. We argue here that glycated LDL shows many of the characteristics attributed to 'oxidised LDL' and may be the source of the latter in vivo. These include the increased uptake and impaired (...) degradation of glycated LDL by macrophages and the stimulation of transendothelial chemotaxis of monocytes, cytokine secretion and platelet aggregation. We hypothesise that the covalent binding of glycated LDL to the endothelial cell wall may result in the formation of the early atherosclerotic lesion of the fatty streak and that apolipoprotein E may mediate the physiological clearance of glycated moieties. The proposed role of glycation in the pathogenesis of atherosclerosis would explain its high incidence among diabetics and the contentious epidemiological and experimental correlations between dietary sugar and atherosclerosis.

The study on argumentation has been developed until it becoming into an independent studying field since mid last century. Nowadays, this field embraces its own academic structure of magazines, books series, societies, symposiums, Internet Web Pages, experts systems, and it even takes place within departments and curriculums concerning certain Universities' media, which attempt to give an academic discipline shape to the argumentation..

Les hypothèses sur l’innéité d’un trait formulées par les sciences cognitives – l’hypothèse d’une faculté innée de langage, par exemple – peuvent-elles échapper à la tautologie? Aucune définition générale de l’innéité ne semble pleinement satisfaisante. En tant que notion dispositionnelle, l’innéité rencontre le « problème de la tautologie » mis en évidence par Locke. Les jugements en matière d’innéité, qu’ils relèvent d’une théorie innéiste ou d’une théorie empiriste (puisque même les empiristes doivent en formuler), dépendent toujours d’une vision particulière du (...) développement cognitif. Ce fait ne condamne pourtant pas ces jugements à la tautologie mais offre au contraire un critère opératoire externe qui permet de les justifier : une explication développementale jugée pertinente permettra de formuler des hypothèses solides en matière d’innéité.

Facultés, concepts, théories et modules innés... Le débat philosophique contemporain sur la structure naturelle de l'esprit multiplie les références aux idées innées. Noam Chomsky lui-même, défenseur d'une faculté innée de langage, s'inscrit dans la lignée de la philosophie moderne. Mais les idées innées contemporaines ont-elles le même sens que celles posées par Descartes et Leibniz? Les progrès des sciences biologiques et cognitives permettent-ils d'attester ou d'infirmer l'existence des idées innées? L'étude analyse les théories modernes et contemporaines des idées innées puis (...) propose une définition de l'innéisme qui démontre l'actualité du débat amorcé à l'âge classique entre innéisme et empirisme."--Page 4 of cover.

The purpose of this article is to point out five aspects of Nietzschean thought that may be relevant to debates in the philosophy of science around the nature and representation of scientific knowledge. To this end, a literature review is carried out with the aim of selecting excerpts from Nietzschean works such as The Birth of Tragedy, Genealogy of Morals, The Gay Science and others that allow us to interpret Nietzsche as a philosopher of science concerned with the construction of (...) scientific knowledge about the physical reality. As a result, it is possible to identify an epistemological proposal in the Nietzschean perspective, whose objective representation of the world should point to an aesthetics of life. (shrink)

In his 1978 paper “Mathematical Explanation”, Mark Steiner attempts to modernize the Aristotelian idea that to explain a mathematical statement is to deduce it from the essence of entities figuring in the statement, by replacing talk of essences with talk of “characterizing properties”. The language Steiner uses is reminiscent of language used for proofs deemed “pure”, such as Selberg and Erdős’ elementary proofs of the prime number theorem avoiding the complex analysis of earlier proofs. Hilbert characterized pure proofs as those (...) that use only “means that are suggested by the content of the theorem”, a characterization we have elsewhere called “topical purity”. In this paper we will examine the connection between Steiner’s account of mathematical explanation and topical purity. Are Steiner-explanatory proofs necessarily topically pure? Are topically pure proofs necessarily Steiner-explanatory? Answers to these questions will shed light on the general question of the relation between purity and explanatory power. (shrink)

For more than a century, Harlem has been the epicenter of black America, the celebrated heart of African American life and culture—but it has also been a byword for the problems that have long plagued inner-city neighborhoods: poverty, crime, violence, disinvestment, and decay. Photographer Camilo José Vergara has been chronicling the neighborhood for forty-three years, and Harlem: The Unmaking of a Ghetto is an unprecedented record of urban change. Vergara began his documentation of Harlem in the tradition of such (...) masters as Helen Levitt and Aaron Siskind, and he later turned his focus on the neighborhood’s urban fabric, both the buildings that compose it and the life and culture embedded in them. By repeatedly returning to the same locations over the course of decades, Vergara is able to show us a community that is constantly changing—some areas declining, as longtime businesses give way to empty storefronts, graffiti, and garbage, while other areas gentrify, with corporate chain stores coming in to compete with the mom-and-pops. He also captures the ever-present street life of this densely populated neighborhood, from stoop gatherings to graffiti murals memorializing dead rappers to impersonators honoring Michael Jackson in front of the Apollo, as well as the growth of tourism and racial integration. Woven throughout the images is Vergara’s own account of his project and his experience of living and working in Harlem. Taken together, his unforgettable words and images tell the story of how Harlem and its residents navigated the segregation, dereliction and slow recovery of the closing years of the twentieth century and the boom and racial integration of the twenty-first century. A deeply personal investigation, Harlem will take its place with the best portrayals of urban life. (shrink)

Our visual experience seems to suggest that no continuous curve can cover every point of the unit square, yet in the late 19th century Giuseppe Peano proved that such a curve exists. Examples like this, particularly in analysis received much attention in the 19th century. They helped to instigate what Hans Hahn called a ‘crisis of intuition’, wherein visual reasoning in mathematics came to be thought to be epistemically problematic. Hahn described this ‘crisis’ as follows : " Mathematicians had for (...) a long time made use of supposedly geometric evidence as a means of proof in much too naive and much too uncritical a way, till the unclarities and mistakes that arose as a result forced a turnabout. Geometrical intuition was now declared to be inadmissible as a means of proof … "Avoiding geometrical evidence, Hahn continued, mathematicians aware of this crisis pursued what he called ‘logicization’, ‘when the discipline requires nothing but purely logical fundamental concepts and propositions for its development’. On this view, an epistemically ideal mathematics would minimize, or avoid altogether, appeals …. (shrink)

We study Hilbert spaces expanded with a unitary operator with a countable spectrum. We show that the theory of such a structure is ω -stable and admits quantifier elimination.

Theoretical accounts of negative expressives such as damn have ascribed two main properties to this type of adjective, namely that they are typically speaker-oriented, and that they can be flexible with regard to their syntactic attachment. However, it is not clear what this means during online sentence processing. For example, is it effortful for comprehenders to derive the speaker's negative attitude conveyed by an expressive adjective, or is it a rapid, automatic process? And do comprehenders understand the speaker's attitude regardless (...) of the expressive's syntactic position? The current work provides the first evidence supporting theoretical claims by investigating the incremental processing of Italian negative expressive adjectives. In an eye-tracking study, we show that expressive content is rapidly integrated with information about the speaker's attitude, resulting in the anticipation of an upcoming referent, regardless of the expressive's syntactic realization. We argue that comprehenders use expressives as an ostensive cue that allows for automatic retrieval of the speaker's negative attitude. (shrink)

In this paper, I critique a popular yet seldom recognized theory of the political role of religious reasons. According to this theory, the Free Marketplace model, laws may be justified on religious reasons as long as such laws do not impinge on rights. I argue that this theory is internally contradictory and can only be defended by either accepting normatively unacceptable consequences, or resorting to ad hoc distinctions between compelling and non-compelling legal justifications.

William Blake and Zadie Smith reached strikingly similar critical positions towards philosophical trends current in their respective eras. Both excoriate those who, for selfish ends, disparage beauty and in so doing sabotage justice, love, joy and genuine freedom. Smith’s On Beauty, like Blake’s America: A Prophecy and Visions of the Daughters of Albion, indicts the reprehensible intellectual discourses of the day that undermine human happiness and corrupt the social order. Whereas Blake critiqued the rights revolutions set in motion by Thomas (...) Paine, William Godwin, Mary Wollstonecraft and others from a more broadly moral and future-oriented angle than has generally been recognized (as Saree Makdisi has shown), Smith wittily dramatizes that same vision through a huge range of up-to-date ideological discourses and antagonisms–many of them descended from Paine et al.–to refurbish Blake’s particular brand of radical antinomianism and to celebrate much the same optimistic spirit that Blake invested in America and Visions. Indeed, Smith’s novel anticipates and critiques ab ovo the sweepingenthusiasms that are animating current uprisings worldwide. (shrink)

l propósito de este trabajo es indagar la relación existente entre el fenóme-no de la ciencia, su eclosión y progreso, y la presencia de una atmósfera cultural cristiana. Se trata de dirimir si en la práctica han dominado más las voces que dentro del cristianismo han alentado a los investigadores o si han predominado más las que la han cohibido y reprimido. El autor se inclina por la primera alternativa. A través de una mirada histórica, constata las profundas raíces cristianas (...) de la ciencia moderna. (shrink)

La pregunta acerca de qué es un humano tiene una respuesta trivial: cualquier individuo perteneciente a la especie Homo sapiens. Pero si nos interrogamos por el sentido de lo que es un ser humano, cuáles son los rasgos distintivos respecto de otras especies, cómo evolucionaron y por qué, en qué medida los antecesores nuestros disponían de ellos y dónde y cuándo vivieron esos ancestros, entonces entramos en un terreno de difícil recorrido. En los últimos siete millones de años existieron varias (...) especies a las que cabe llamar «humanas» o, por lo menos, «homínidas». Es éste un repaso breve y muy sintético de lo que supuso tal panorama diverso y dinámico que conduciría, a la postre, a los humanos actuales. Nuestras propias características adquieren una nueva luz cuando se contemplan a lo largo del proceso de su filogénesis. (shrink)

La infancia es un hecho social y por este principio no se reduce a una única expresión. En Colombia, las investigaciones de la memoria histórica han omitido esta concepción sociológica al resumir la interacción de la guerra y la infancia al estudio del reclutamiento de menores de edad.

Para tal fin, propone empezar por cuatro infancias (la (...) desplazada, la masacrada, la desaparecida y la violentada sexualmente), tomando en cuenta algunas herramientas metodológicas e interpretativas para abordarlas.

Este ensaio explora a superação do sofrimento pela arte trágica na teoria da tragédia grega de Friedrich Nietzsche, com foco nas seções 7 a 10 de O nascimento da tragédia. Iniciamos a análise em Nietzsche apresentando o papel crucial do coro na transformação do dionisíaco em uma experiência estética disruptiva e a ideia do trágico como um critério para pensar a profundidade filosófica da arte grega. Em seguida, consideramos a questão do conceito hegeliano de Aufhebung em Nietzsche e sua relevância (...) para a tese da arte como feiticeira da verdade. Por fim, destacamos a capacidade única da tragédia em explorar tensões fundamentais da existência em suas complexidades, contradições e a prazeres inerentes à vida. (shrink)

During the last few months, several pioneer genome‐wide transcriptomic, proteomic and metabolomic studies have revolutionised the understanding of bacterial biological processes, leading to a picture that resembles eukaryotic complexity. Technological advances such as next‐generation high‐throughput sequencing and high‐density oligonucleotide microarrays have allowed the determination, in several bacteria, of the entire boundaries of all expressed transcripts. Consequently, novel RNA‐mediated regulatory mechanisms have been discovered including multifunctional RNAs. Moreover, resolution of bacterial proteome organisation (interactome) and global protein localisation (localizome) have unveiled an (...) unanticipated complexity that highlights the significance of protein multifunctionality and localisation in the cell. Also, analysis of a complete bacterial metabolic network has again revealed a high fraction of multifunctional enzymes and an unexpectedly high level of metabolic responses and adaptation. Altogether, these novel approaches have permitted the deciphering of the entire physiological landscape of one of the smallest bacteria, Mycoplasma pneumoniae. Here, we summarise and discuss recent findings aimed at defining the blueprint of any prokaryote. (shrink)

We compare two different elicitation methods for measuring risk attitudes on a sample of French farmers. We consider the lottery tasks initially proposed by Holt and Laury (Econ Rev 92:1644–1655, 2002) and by Eckel and Grossman (Evol Hum Behav 23:281–295, 2002; J Econ Behav Org 68:1–7, 2008). The main empirical result from this within-subject study is that risk preference measures are affected by the type of mechanism used. We first show that this risk preference instability can be related to non-expected (...) utility preferences of farmers. Using a risk-taking psychometric questionnaire, we then demonstrate that risk preferences of farmers are context-dependent. This may be another explanation of the observed risk preference instability. (shrink)

This study focuses on the differences in the perception of business ethics across two groups of management students from France and Romania (n = 220). Data was collected via the ATBEQ to measure preferences for three business philosophies: Machiavellianism, Social Darwinism, and Moral Objectivism. The results show that Romanian students present more favorable attitudes toward Machiavellianism than French students; whereas, French students valued Social Darwinism and Moral Objectivism more highly. For Machiavellianism and Moral Objectivism the results are consistent with the (...) literature and our hypotheses. However, contrary to our expectations, we find that Social Darwinism is more important in France than Romania. The results indicate that religious practice does not influence preferences for the three business philosophies. In terms of gender differences, women have less favorable attitudes toward Machiavellianism and more favorable attitudes toward Moral Objectivism than men. (shrink)

Why do we have social norms—of fairness, cooperation, trust, property, or gender? Modern-day Humeans, as I call them, believe these norms are best accounted for in cultural evolutionary terms, as adaptive solutions to recurrent problems of social interaction. In this paper, I discuss a challenge to this “Humean Program.” Social norms involve widespread behaviors, but also distinctive psychological attitudes and dispositions. According to the challenge, Humean accounts of norms leave their psychological side unexplained. They explain, say, why we share equally, (...) but not why we disapprove of those who don’t. I defend the Humean Program against this challenge. In particular, I suggest an idea for how to extend the Program to account for the psychological side of norms. Socially adaptive behaviors aren’t just likely to emerge in a group; They are also likely to be widely taught within it. The transmission of these behaviors through instruction explains why they are associated with distinctive normative attitudes and dispositions. These attitudes play a pedagogical role in helping transmit these behaviors to children and newcomers. (shrink)

Many mathematicians have cited depth as an important value in their research. However, there is no single widely accepted account of mathematical depth. This article is an attempt to bridge this gap. The strategy is to begin with a discussion of Szemerédi's theorem, which says that each subset of the natural numbers that is sufficiently dense contains an arithmetical progression of arbitrary length. This theorem has been judged deep by many mathematicians, and so makes for a good case on which (...) to focus in analyzing mathematical depth. After introducing the theorem, four accounts of mathematical depth will be considered. (shrink)

Como imperturbables representantes de la teología cristiana, Santo Tomás y Leibniz adhieren prima facie a la tesis según la cual el mundo es una creación divina a partir de la nada (creatio ex nihilo), elevando esta verdad a la categoría de misterio o milagro de la religión. Pese a que el mismo Leibniz invoque la autoridad de Santo Tomás para circunscribir la creación del mundo en el contexto de la Revelación, el estatus epistemológico de las pruebas o argumentos sobre cuya (...) base ambos justifican la tesis de la creatio ex nihilo es diferente: mientras que el aquinate reconoce que, habiendo sido creado de la nada, el mundo podría haber sido eterno -con lo cual Santo Tomás apunta a preservar intacta la omnipotencia de Dios-, el polímata alemán piensa de manera diferente, a saber, que no es racionalmente demostrable que el mundo existente o actual no sea, en efecto, eterno. De hecho, en ciertos pasajes, Leibniz sugiere que el mundo, en vez de ser el resultado de una creación, puede ser concebido como una eterna emanación divina. Sobre la base de diversas piezas textuales de ambos autores, nuestro propósito consiste en esbozar un estudio comparativo que examine inicialmente la manera en que Leibniz, apoyándose en la autoridad de Santo Tomás, concibe la creación divina del mundo al interior de su metafísica teológica (sección 1) con el objeto de analizar retrospectivamente, en una segunda etapa, la doctrina creacionista de Santo Tomás (sección 2), para así determinar si, finalmente, ambos sostienen o no una doctrina filosófica coincidente acerca de la creación en el plano metafísico-teológico (sección 3).

Part of the task of doing moral philosophy is to strengthen our confidence in morality or to bring back the gravitas of morality. I argue that this cannot be done by a representational view of moral reality and by downplaying the importance of human sentiments that make our moral assertions more natural and authentic.
