Hybrid languages are expansions of propositional modal languages which can refer to worlds. The use of strong hybrid languages dates back to at least [Pri67], but recent work has focussed on a more constrained system called $\mathscr{H}$. We show in detail that $\mathscr{H}$ is modally natural. We begin by studying its expressivity, and provide model theoretic characterizations and a syntactic characterization. The key result to emerge is that $\mathscr{H}$ corresponds to the fragment of first-order logic which is invariant for generated (...) submodels. We then show that $\mathscr{H}$ enjoys interpolation, provide counterexamples for its finite variable fragments, and show that weak interpolation holds for the sublanguage $\mathscr{H}$. Finally, we provide complexity results for $\mathscr{H}$ and other fragments and variants, and sharpen known undecidability results for $\mathscr{H}$. (shrink)

This chapter subsumes David Marr’s levels of analysis account of explanation in cognitive science under the framework of mechanistic explanation: Answering the questions that define each one of Marr’s three levels is tantamount to describing the component parts and operations of mechanisms, as well as their organization, behavior, and environmental context. By explicating these questions and showing how they are answered in several different cognitive science research programs, this chapter resolves some of the ambiguities that remain in Marr’s account, and (...) shows that many different areas and traditions of cognitive scientific research can be unified under the mechanistic framework.

In this book, Carlos Montemayor and Harry Haladjian consider the relationship between consciousness and attention. The cognitive mechanism of attention has often been compared to consciousness, because attention and consciousness appear to share similar qualities. But, Montemayor and Haladjian point out, attention is defined functionally, whereas consciousness is generally defined in terms of its phenomenal character without a clear functional purpose. They offer new insights and proposals about how best to understand and study the relationship between consciousness and attention (...) by examining their functional aspects. The book's ultimate conclusion is that consciousness and attention are largely dissociated. -/- Undertaking a rigorous analysis of current empirical and theoretical work on attention and consciousness, Montemayor and Haladjian propose a spectrum of dissociation—a framework that identifies the levels of dissociation between consciousness and attention—ranging from identity to full dissociation. They argue that conscious attention, the focusing of attention on the contents of awareness, is constituted by overlapping but distinct processes of consciousness and attention. Conscious attention, they claim, evolved after the basic forms of attention, increasing access to the richest kinds of cognitive contents. -/- Montemayor and Haladjian's goal is to help unify the study of consciousness and attention across the disciplines. A focused examination of conscious attention will, they believe, enable theoretical progress that will further our understanding of the human mind. (shrink)

This book presents practical holism as a framework for understanding the ways in which our society and individual lives are affected by moral, legal, political, economic, and other considerations. Only nomadic thought is able to capture the interactions among all those crucial aspects.

The Aymara of the Andes use absolute (cardinal) frames of reference for describing the relative position of ordinary objects. However, rather than encoding them in available absolute lexemes, they do it in lexemes that are intrinsic to the body: nayra (“front”) and qhipa (“back”), denoting east and west, respectively. Why? We use different but complementary ethnographic methods to investigate the nature of this encoding: (a) linguistic expressions and speech–gesture co-production, (b) linguistic patterns in the distinct regional Spanish-based variety Castellano Andino (...) (CA), (c) metaphorical extensions of CA’s spatial patterns to temporal ones, and (d) layouts of traditional houses. Findings indicate that, following fundamental principles of Aymara cosmology, people, objects, and land—as a whole—are conceived as having an implicit canonical orientation facing east, a primary landmark determined by the sunrise. The above bodily based lexicalizations are thus linguistic manifestations of a broader macro-cultural worldview and its psycho-cognitive reality. (shrink)

RESUMO: O presente artigo aborda um tema específico da fenomenologia de Husserl: o problema da autoconstituição do eu transcendental. O artigo se encontra dividido em duas partes. Inicialmente, investiga o eu como polo idêntico que acompanha todos os vividos. Em seguida, introduz o problema da autoconstituição: ao constituir seus objetos, o eu transcendental se autoconstitui. Por fim, retoma o referido problema, para investigar a gênese temporal da vida subjetiva e a autoconstituição do ego por meio dos seus próprios habitus. ABSTRACT: (...) The present paper approaches a specific topic in Husserl's phenomenology: the problem of the self-constitution of the transcendental ego. The article is divided into two parts. First, the ego as an identical pole that accompanies every experience is investigated. Next the problem of self-constitution is introduced: in constituting the object, the transcendental ego constitutes itself. Finally, the temporal genesis of subjective life and the self-constitution of the ego through its own habitus is discussed. (shrink)

This book offers an account of exile in terms of the perspectives of morality, politics, literature, anthropology, and history. It also explores the moral implications of exile and how it connects to the meaning of life.

Uma das questões que desafia educadores e educador@s [1], inserid@s no campo da relação que envolve os processos de ensino e de aprendizagem, consiste no papel da educação do ponto de vista da vida em sociedade. E uma resposta aceita de forma genérica aponta para a dimensão da humanização. Questiona-se: até que ponto a relação educativa possui a capacidade e potencialidade de humanizar? Como relacionar a construção do conhecimento à perspectiva de valoração que promova a sociabilidade humana? A partir destes (...) questionamentos abordamos duas dimensões fundamentais: a ética e a moral, campos que estão na base da cultura, do mito, das relações de poder e, portanto, da política. Assim, esse texto objetiva refletir sobre os impactos da ética e da moral nas relações de poder e no processo de humanização, apontando para uma relação dialógica, na perspectiva da alteridade, como uma das saídas viáveis para a humanidade. E para tanto, utilizamos Martin Buber (1974, 1987) e Paulo Freire (1979, 1983) como principais referências teóricas, pensando o papel da educação no enfrentamento deste problema. A partir das leituras, compreendemos o conceito de alteridade, que aponta para o caminho da desmitologização da realidade por meio desta mesma dimensão, que pode ser compreendida no campo da educação. Concluímos que, somente na perspectiva da ética, esta relação pode ser dialógica. E, somente na relação dialógica este processo pode ser transformador e libertador. Esse procedimento educativo potencializa relações de solidariedade e, consequentemente, humaniza em seu significado mais pleno de ser com @ outr@. [1] Utilizamos o símbolo “@” para referenciar de modo simultâneo os gêneros feminino e masculino. Trata-se de um posicionamento político-cultural que vem de encontro às normas gramaticais postas.

Three philosophical attitudes in dialogue are suggested in answering the question posed by the Journal. An inviting, First Inner Voice undeerstands philosophy as a shareable theoretical task that can be explained and understood even across distant philosophical paradigms. A Second Inner Voice, sometimes termed in the dialogue as sceptic, distrusts any metaphilosophical definition of what philosophy is and what it should do, but would, nevertheless, aspire to retain a certain universalistic understanding of its own work, though it cannot be strongly (...) and conceptualy rendered. A Third Inner Voice, regarded in the text as somewhat Hegelian, insists in the unavoidability of strong philosophical definitions both in historical and in conceptual terms. No proposal or conclusion is forwarded regarding what should be done in contemporary philosophy, though an analysis of harm experiences is taken as an example of philosophical work. (shrink)

This paper aims to investigate the relationship between the phenomenological epoché and the phenomenological problem of the relationship between the consciousness and the world. Initially, the article examines the first implication of the exercise of epoché : the idea of "loss of the world." Then examines the second implication of this exercise: the idea of "recovery of the world" in the transcendental consciousness. Finally, the article elucidates the specificity of phenomenological idealism of Husserl. The widespread exercise of the epoché does (...) not imply a denial of the existence of the world. The task of this idealism is elucidate the phenomenological sense of this world that is formed intentionally in the transcendental subjectivity. (shrink)

O presente artigo aborda a dupla tarefa da teoria do conhecimento nas “Cinco Lições” de Edmund Husserl: a tarefa crítica denuncia o contrasenso inerente aos tipos de ceticismo em relação ao conhecimento; a tarefa positiva promove a pergunta pela essência do conhecimento. O artigo destaca que a dupla tarefa da teoria do conhecimento é o que determina o itinerário das “Cinco Lições”. O artigo revela, por fim, que a teoria do conhecimento equipara-se a uma fenomenologia do conhecimento, e o que (...) vale para esta fenomenologia valerá para a fenomenologia em geral. (shrink)

In this paper, I propose that time representation should be classified as agent dependent motor-intentional, agent dependent conceptual and agent independent conceptual. I employ this classification to explain certain features of psychological and cultural time and discuss how biological time constrains such features. The paper argues that motor-intentional time is a crucial psychophysical link that bridges the gap between purely biochemical cycles and conceptual-intentional representations of time, and proposes that the best way to understand the transitions from biological to psychological (...) time is to characterize them as phase transitions that emerge on the global properties of a system regardless of specific aspects of the underlying processing units. With respect to hierarchical models of time, the paper claims that although the hierarchical organization of constraints limits the number of possible instantiations of temporal information, informational phases have principles of organization of their own. Based on these proposals, I conclude that since information assembles itself into the temporal behavior of an agent, it is more accurate to call the principles governing such a behavioral unity a phase, rather than a hierarchy. To support these theses, the paper draws upon research in biology, neuroscience, philosophy and psychology. (shrink)

La conquista del poder por la izquierda ha tenido un carácter internacional desde su génesis en el siglo XIX. Esta aproximación colaborativa permite contextualizar lo que significó el Foro de São Paulo a finales del siglo XX para la izquierda latinoamericana tras la desintegración de la URSS. Por lo que se analiza al Socialismo del siglo XXI como su principal producto, explicando las circunstancias que permitieron su surgimiento en Venezuela, así como su proceso de expansión y crisis, que se vería (...) acentuada por la muerte de los líderes históricos de la izquierda latinoamericana. Finalmente, se presenta al Grupo de Puebla como una respuesta a la iniciativa articuladora de la derecha en América Latina, el Grupo de Lima, indicando por medio de ello los elementos de continuidad y disrupción con el Foro de São Paulo, sirviendo como instancia articuladora de la izquierda en la región.

Este trabajo no pretende seguramente aportar nada nuevo a la filosofía práctica. Nuestro propósito, más bien, es hacer algunas reflexiones acerca del filosofar mismo desde una perspectiva popperiana, pues consideramos que ella puede suministrar algunas herramientas útiles para aquellos que se ocupan de la filosofía práctica y la aplican. Se trata de ver a la filosofía como una actividad crítica de las nociones o creencias compartidas que aparecen como �sentido común�. En definitiva, consideramos que una filosofía práctica puede cumplir un (...) papel útil, incluso indispensable, si nunca pierde ese aguijón crítico, aguijón que es también indispensable en la llamada filosofía académica.

En este artículo se sintetiza una visión moderna de las lógicas modales y temporales. En vez de dar una motivación histórica, el paper presenta estas lógicas en relación con ciertos fragmentos de la lógica de primer orden que poseen propiedades interesantes. Esta visión de la lógica es seductora porque nos permite diseñar lenguajes a medida, es decir, optimizados para una tarea específica.

Previous research has demonstrated that ratings of the perceived pleasantness and quality of odors can be modulated by auditory stimuli presented at around the same time. Here, we extend these results by assessing whether the hedonic congruence between odor and sound stimuli can modulate the perception of odor intensity, pleasantness, and quality in untrained participants. Unexpectedly, our results reveal that broadband white noise, which was rated as unpleasant in a follow-up experiment, actually had a more pronounced effect on participants’ odor (...) ratings than either the consonant or dissonant musical selections. In particular, participants rated the six smells used as being less pleasant and less sweet when they happened to be listening to white noise, as compared to any one of the other music conditions. What is more, these results also add evidence to support the existence of a close relationship between an odor’s hedonic character and the perception of odor quality. So, for example, independent of the sound condition, pleasant odors were rated as sweeter, less dry, and brighter than the unpleasant odors. These results are discussed in terms of their implications for the understanding of crossmodal correspondences between olfactory and auditory stimuli. (shrink)

Movements of the Mind offers a compelling and empirically grounded theory of agency and attention, arguing that the structure of action depends on the capacity of attention. This capacity is also central to the explanation of how memory can be geared towards immediate action, as memory 'for work', because attention is essential for the solution of selection problems that require working memory. This seemingly simple structure has substantial and broad consequences for various aspects of cognition, allowing for the integration of (...) automatic processing and top-down routines with the articulation of physical and mental action. This account of agency and attention is also applicable to non-human cognition. (shrink)

A central claim in Luiz Pessoa’s (2013) book is that the terms “emotion” and “cognition” can be useful in characterizing behaviors but will not be cleanly mapped into brain regions. In order to be verified, this claim requires models for the integration and interfacing of emotion and cognition; yet, such models remain problematic.

Neste artigo, procura-se enquadrar na perspetiva da retórica e da argumentação a problemática do chamado “negacionismo” da COVID-19, entendendo-se por um tal conceito não tanto ou simplesmente a rejeição da identificação médica dessa doença, mas, fundamentalmente, quer a negação da sua gravidade e a da sua amplitude pandémica como matéria de saúde pública, quer a negação das medidas adotadas para a combater, de maneira geral, pelas autoridades competentes. As posições defendidas sobre o assunto por uma autoridade médica especializada, mas rotulada (...) e estigmatizada como “negacionista” (Fernando Nobre, médico, ex-Professor catedrático convidado da Faculdade de Medicina da Universidade de Lisboa e doutor honoris causa pela mesma Universidade), servem de caso em estudo.

Algunas experiencias del siglo XX -Auschwitz, el Gulag, Hiroshima- han vuelto a herir la conciencia ilustrada y replanteado el problema del mal en nuestra cultura. Más que una indagación metafísica sobre la naturaleza del mal, el artículo aboga por un análisis de cómo llegamos a elaborar su experiencia, un proceso que aquí prefiere concebirse como una indagación en torno al daño. Se analizan las estructuras conceptuales, modales y temporales de esa experiencia y, en la segunda parte, se propone la idea (...) de que la elaboración pública del daño es una clave para comprender la dimensión normativa del espacio público.
