In diesem Beitrag möchte ich mich darauf beschränken, einige Aspekte von Fichtes Verhältnis zu Kant zu berücksichtigen, die mir sowohl für das Verständnis Fichtes als auch für das Verständnis Kants sehr lehrreich zu sein scheinen. Denn die Einsicht in die unterschiedlichen Auffassungen des alten und des jungen Denkers läßt um so mehr da, wo der zweite meint, den ersten bloß zu wiederholen, treu zu interpretieren oder allenfalls treu weiterzudenken, den Geist der beiden philosophischen Ansätze am deutlichsten zutage treten. Den manchmal (...) unbestimmten Ausdruck »Geist« darf man in diesem Fall wohl verwenden, da die Textstellen, die dem Vergleich feste Bezugspunkte angeben, nicht isoliert dastehen, sondern jeweils in zwei verschiedene und scharf konturierte philosophische Ansätze hinein konvergieren.

In their attempt to connect the workings of the human mind with their neural realizers, cognitive neuroscientists often bracket out individual differences to build a single, abstract model that purportedly represents (almost) every human being’s brain. In this paper I first examine the rationale behind this model, which I call ‘Platonic Brain Model’. Then I argue that it is to be surpassed in favor of multiple models allowing for patterned inter-individual differences. I introduce the debate on legitimate (and illegitimate) ways (...) of mapping neural structures and cognitive functions, endorsing a view according to which function-structure mapping is context-sensitive. Building on the discussion of the ongoing debate on the function(s) of the so-called Fusiform “Face” Area, I show the necessity of indexing function-structure mappings to some populations of subjects, clustered on the basis of factors such as their expertise in a given domain.

In his article, ‘Social constructionism and climate science denial’, Hansson claims to present empirical evidence that the cultural theory developed by Dame Mary Douglas, Aaron Wildavsky and ourselves leads to science denial. In this reply, we show that there is no validity to these claims. First, we show that Hansson’s empirical evidence that cultural theory has led to climate science denial falls apart under closer inspection. Contrary to Hansson’s claims, cultural theory has made significant contributions to understanding and addressing climate (...) change. Second, we discuss various features of Douglas’ cultural theory that differentiate it from other constructivist approaches and make it compatible with the scientific method. Thus, we also demonstrate that cultural theory cannot be accused of epistemic relativism. (shrink)

This article makes first a critical review of the different definitions in the scientific literature of the 'underclass' concept. It is argued that the American and British concept of underclass is not necessarily transportable to Europe. The next part adresses the question of a possible emerging urban underclass in Belgium.It is concluded that although Belgium has to fight against social problems associated with underclass formation in the US and Britain, it has until now no clearcut underclass. The main reasons for (...) this are that economic marginality is not permanent and stable, and that economic marginality, deviant values and criminal behaviour are not systematically coinciding.

Since Austin and Searle, performatives are taken to be crucial for the construction of social reality. More recently, performatives have been proposed to be essential for the construction of personal identities, too. I intend to analyze the postmodern assumption according to which this identity construction is in the power of individuals, an assumption which presupposes a view of performatives as endowed with unconstrained power – that is, with a power that is not subject to objective constraints. I will consider some (...) reasons to reject this view. The first is rooted in Judith Butler’s idea that – since normative approaches to political correctness undesirably reduce freedom of speech in the name of equality – we should seriously consider how offensive performatives may fail, due to objective constraints on their felicity. A second reason to reject the postmodern view of performatives lies in the consideration of narcissism as an individual and political issue. Narcissism in the political sphere can be described as a transformation of the “passion for equality” in an individualistic appetite, deaf to everything else, and especially to social constraints and responsibilities. A different – less narcissistic and more social – model of the self is provided. (shrink)

Humans have been using fire for hundreds of millennia, creating an ancestral expansion toward the nocturnal niche. The new adaptive challenges faced at night were recurrent enough to amplify existing psychological variation in our species. Night-time is dangerous and mysterious, so it selects for individuals with higher tendencies for paranoia, risk-taking, and sociability. During night-time, individuals are generally tired and show decreased self-control and increased impulsive behaviors. The lower visibility during night-time favors the partial concealment of identity and opens more (...) opportunities for disinhibition of self-interested behaviors. Indeed, individuals with an evening-oriented chronotype are more paranoid, risk-taking, extraverted, impulsive, promiscuous, and have higher antisocial personality traits. However, under some circumstances, such as respiratory pandemics, the psychobehavioral traits favored by the nocturnal niche might be counter-productive, increasing contagion rates of a disease that can evade the behavioral immune system because its disease cues are often nonexistent or mild. The eveningness epidemiological liability hypothesis presented here suggests that during the COVID-19 pandemic, the evening-oriented psychobehavioral profile can have collectively harmful consequences: there is a clash of core tendencies between the nocturnal chronotype and the recent viral transmission-mitigating safety guidelines and rules. The pandemic safety protocols disrupt much normal social activity, particularly at night when making new social contacts is desired. The SARS-CoV-2 virus is contagious even in presymptomatic and asymptomatic individuals, which enables it to mostly evade our evolved contagious disease avoidance mechanisms. A growing body of research has indirectly shown that individual traits interfering with social distancing and anti-contagion measures are related to those of the nocturnal chronotype. Indeed, some of the social contexts that have been identified as superspreading events occur at night, such as in restaurants, bars, and nightclubs. Furthermore, nocturnal environmental conditions favor the survival of the SARS-CoV-2 virus much longer than daytime conditions. We compare the eveningness epidemiological liability hypothesis with other factors related to non-compliance with pandemic safety protocols, namely sex, age, and life history. Although there is not yet a direct link between the nocturnal chronotype and non-compliance with pandemic safety protocols, security measures and future empirical research should take this crucial evolutionary mismatch and adaptive metaproblem into account, and focus on how to avoid nocturnal individuals becoming superspreaders, offering secure alternatives for nocturnal social activities.

Since cognitive neuroscience aims at giving an integrated account of mind and brain, its ontology should include both neural and cognitive entities and specify their relations. According to what we call the standard ontological framework of cognitive neuroscience, the aim of cognitive neuroscience should be to establish one-to-one mappings between neural and cognitive entities. Where such entities do not yet closely align, this can be achieved by reforming the cognitive ontology, the neural ontology, or both. In order to assess the (...) limits and the possibilities of the SOFCN, we will examine a paradigmatic case study: the concept of Broca’s area, which indicates an alleged mapping between the left inferofrontal gyrus and the production of language. We review evidence showing that such a mapping does not hold, thus calling into question either the status of Broca’s area or the validity of the SOFCN. We then propose some strategies for addressing the issue and suggest that it may be solved within the SOFCN by adopting both of the following strategies: first, more accurately defining the relevant neural structures and second, switching the focus of neural ontology from structures to events, individuated by a where conjoint with a how.

We offer a novel picture of mathematical language from the perspective of speech act theory. There are distinct speech acts within mathematics, and, as we intend to show, distinct illocutionary force indicators as well. Even mathematics in its most formalized version cannot do without some such indicators. This goes against a certain orthodoxy both in contemporary philosophy of mathematics and in speech act theory. As we will comment, the recognition of distinct illocutionary acts within logic and mathematics and the incorporation (...) of illocutionary force indicators in the formal language for both goes back to Frege’s conception of these topics. We are, therefore, going back to a Fregean perspective. This paper is part of a larger project of applying contemporary speech act theory to the scientific language of mathematics in order to uncover the varieties and regular combinations of illocutionary acts present in it. For reasons of space, we here concentrate only on assertive and declarative acts within mathematics, leaving the investigation of other kinds of acts for a future occasion. (shrink)

El imaginario poético que emerge de la cultura porteña del Pacífico Sur es un producto de la imaginación que responde a un ejercicio escritural histórico. Hacemos un repaso de estas manifestaciones a partir de tres momentos o sensibilidades que construyen una imagen del puerto de Valparaíso. Desde el relato de viaje, el gesto modernista y la narrativa del naturalismo, todos previos a un producto estético-literario mayor, enseñan en su mirada un modo de habitar el puerto que permiten proponer la existencia (...) de una cultura en conflicto con Occidente. Los pasajes de estas manifestaciones no pueden leerse aislados de esa poética del habitar porteño, sino como parte integral de un discurso de frontera que se pronuncia contra el olvido y a favor de la sobrevivencia histórica de estos puertos.

Neste trabalho a noção de fenômeno saturado, proposta por Jean-Luc Marion, é apresentada criticamente e revista. Apoiando-se nas objeções levantadas por L.B. Puntel, que têm um impacto considerável sobre o projeto de Marion de pensar Deus exclusivamente de um ponto de vista fenomenológico, o autor revê o fenômeno saturado através de um retorno à sua fonte primeira: a terceira Crítica de Kant. Desta forma, a natureza simbólica desse fenômeno fica enfatizada, assim como sua constituição estrutural pela imaginação analógica. Em seguida, (...) enfocando o tipo específico de fenômeno saturado que é o fenômeno da revelação, mostra-se como esta versão revista da noção de Marion é adequada para se pensar a experiência do sagrado. Por fim, corrobora-se esse ponto de vista por meio de uma breve alusão à concepção de experiência religiosa em Rudolf Otto. (shrink)

In this event-related potential study a masking technique that prevents conscious perception of words and non-words through attentional distraction was used to reveal the temporal dynamics of word processing under non-conscious and conscious conditions. In the non-conscious condition, ERP responses differed between masked words and non-words from 112 to 160 ms after stimulus-onset over posterior brain areas. The early onset of the word–non-word differences was compatible with previous studies that reported non-conscious access to orthographic information within this time period. Moreover, (...) source localisations provided evidence for automatic activation of prelexical phonological information, whereas no evidence for non-conscious semantic processing was found. When subjects were informed about the masking technique, lexical differences occurred at later time intervals, suggesting conscious access to additional word related information. These results indicate that early visual word processing does not depend entirely on attentional resources, but that non-conscious processing probably is restricted to rather lower-level linguistic information.

Background: Existing ethical guidelines recommend that, all else equal, past receipt of a medical resource (e.g. a scarce organ) should not be considered in current allocation decisions (e.g. a repeat transplantation).DiscussionOne stated reason for this ethical consensus is that formal theories of ethics and justice do not persuasively accept or reject repeated access to the same medical resources. Another is that restricting attention to past receipt of a particular medical resource seems arbitrary: why couldn't one just as well, it is (...) argued, consider receipt of other goods such as income or education? In consequence, simple allocation by lottery or first-come-first-served without consideration of any past receipt is thought to best afford equal opportunity, conditional on equal medical need. There are three issues with this view that need to be addressed. First, public views and patient preferences are less ambiguous than formal theories of ethics. Empirical work shows strong preferences for fairness in health care that have not been taken into account: repeated accessto resources has been perceived as unfair. Second, while difficult to consider receipt of many other prior resources including non-medical resources, this should not be used a motive for ignoring the receipt of any and all goods including the focal resource in question. Third, when all claimants to a scarce resource are equally deserving, then use of random allocation seems warranted. However, the converse is not true: mere use of a randomizer does not by itself make the merits of all claimants equal.SummaryMy conclusion is that not ignoring prior receipt of the same medical resource, and prioritizing those who have not previously had access to the medical resource in question, may be perceived as fairer and more equitable by society.

Tomas Aquinas defined truth as the correspondence between things and understanding. Castro Alves paints the horror of the slave nautical traffic. In his essay On the Concept of History, Walter Benjamin reminds us: “The tradition of the oppressed teaches us that the ‘emergency situation’ in which we live is the rule.” This ‘emergency situation’ was Fascism. Albert Camus defended his romance La Peste against the accusation of Roland Barthes that is was “dehors de l’histoire”, pointing out that it was not (...) only about the recent historical phenomenon of Fascism, but also about the permanent risk of its rebirth. Agnes Heller associates faith with prejudice and alienation. The following article will explore the Thomist concept of truth, Benjamin’s concept of history, Camus’ allegory of the plague, Agnes Heller’s notion of faith and Castro Alves’ powerful denouncement of slave traffic, to better criticize the phenomenon of post-truth, a rebirth of fascist information practices.

In the “Sala dei Mesi” of Palazzo Schifanoia the months and the zodiacal constellations go from right to left, while the decans (three for every sign) go in the opposite direction. This problem was not clarified by Aby Warburg in his well-known essay Italian Art and International Astrology in the Palazzo Schifanoia of Ferrara (1912). The purpose of this paper is to investigate the reasons of this double direction.

Partiendo de la genealogía del neoliberalismo que Michel Foucault traza en _Nacimiento de la biopolítica_ hasta los ordoliberales alemanes, se sostendrá que, si en lugar de haberla basado en sus textos posteriores a la Segunda Guerra Mundial, Foucault hubiera acudido a los textos fundacionales de la época de Weimar: a) no hubiera incurrido en el equívoco de pensar que el papel del Estado fue secundario para estos, y b) habría advertido el carácter autoritario de su propuesta. Así, analizaremos en detalle (...) la inverosímil confluencia en torno a una misma tesis de Carl Schmitt y de los ordoliberales en la década de 1930: Estado fuerte, economía sana. Se concluirá invitando a seguir analizando el papel central del Estado y el autoritarismo en el neoliberalismo, tanto en el pasado como en el presente. (shrink)

El presente artículo analiza el concepto de Diferencia en la filosofía de Gilles Deleuze. Se constata, en este sentido, que la dicotomía inmanencia-trascendencia juega un papel protagónico en la articulación de dicha propuesta. Si bien un plano de composición inmanente no entra en una dialéctica negativa de tipo hegeliano respecto a un plano de organización trascendente, la primacía del primero resulta evidente en la conceptualización de la diferencia. Así, analizaremos las tensiones generadas por dicho enfoque en lo concerniente al despliegue (...) de la diferencia como razón suficiente en un plano inmanente, lo cual nos llevará a problematizar este concepto desde un plano diferente; a saber, un plano inminente que emerge de forma silenciosa en el último trabajo de Gilles Deleuze.

This paper argues that the path integral formulation of quantum mechanics suggests a form of holism for which the whole (total ensemble of paths) has properties that are not strongly reducible to the properties of the parts (the single trajectories). Feynman’s sum over histories calculates the probability amplitude of a particle moving within a boundary by summing over all the possible trajectories that the particle can undertake. These trajectories and their individual probability amplitudes are thus necessary in calculating the total (...) amplitude. However, not all possible trajectories are differentiable, thus suggesting that they are not physical possibilities, but only mathematical entities. It follows that if the possible differentiable trajectories are taken to be part of the physical system, they are not sufficient to calculate the total probability amplitude. The conclusion is that the total ensemble is weakly non-supervenient upon the physically possible trajectories. (shrink)
