El pensamiento de Leopoldo Zea comienza a tomar cuerpo a partir de la década de 1940 y forma parte de un legado representativo para la filosofía latinoamericana y, más específicamente, para la Historia de las Ideas Latinoamericanas. Las reflexiones que volcó en sus libros, y que expuso en foros de discusión que recorrieron el mundo, estuvieron siempre empeñadas en desentrañar el sentido de nuestra historia, con el fin de esclarecer y organizar los saberes y las prácticas de nuestra vida espiritual. (...) Ello, sin perder de vista la necesidad de buscar todos aquellos modos que permitan articular nuestra cultura y nuestra historia con la cultura y la historia universales. Además, su vasta obra contiene importantes aportes que nutren el legado de una tradición siempre orientada a reforzar la afirmación de los ideales de libertad, la autonomía de los pueblos, la integración y, fundamentalmente, la prospectiva de "imaginar sociedades del futuro igualmente deseables para unos y para otros", tal como lo enuncia Don Leopoldo.L. Zea's thinking begun to take shape during the 1940s; they are part of a representative legacy to Latin American philosophy and, more specifically, to the history of Latin American ideas. The reflections in his books, also presented at discussion forums all over the world, always tried to disclose the meaning of our history in order to enlighten and to organize the knowledge and the practices of our spiritual life, this being so without neglecting our concern about the way our history and culture articulate with the universal history and culture. Moreover, his work nourishes a tradition always aimed at strengthening the ideals of freedom, people's autonomy, and integration, and especially the capacity to "imagine future societies just as desirable for all", as don Leopoldo would say.

Following a previous article published in Biological Theory, in this study we present a mathematical theory for a science of qualities as directly perceived by living organisms, and based on morphological patterns. We address a range of qualitative phenomena as observables of a psychological system seen as an impredicative system. The starting point of our study is the notion that perceptual phenomena are projections of underlying invariants, objects that remain unchanged when transformations of a certain class under consideration are applied. (...) The study develops with the observables, the entailed total order and metric, whence the algebra and the geometry of such a science, presenting a formal phenomenological model for phenomena that are not rigidly Euclidean. We show how non-Euclidean perception can have many useful Euclidean formalizations, as well as locally-homeomorphic-to-Euclidean-space models. The mathematical models we provide are tested on the basis of results from experimental psychology, in particular from the field of color, time, and space perception. (shrink)

Scholars describe Global North feminisms as mostly ‘secular’ and often opposing religion. Contemporary feminist intersectional movements seem to offer different approaches able to overcome distances and articulate the role of religion in feminist emancipatory practice. This contribution explores the complex role of religion in intersectional feminist movements, drawing on the experiences of religious-feminist and secular-feminist women in Italy. The results highlight that religious women are increasingly part of feminist intersectional movements. Nonetheless, religious inequalities are often overlooked, and religion triggers ambivalent (...) reactions, often resulting in a process of othering minority women. (shrink)

A recent report from the UN makes the case for “global data literacy” in order to realise the opportunities afforded by the “data revolution”. Here and in many other contexts, data literacy is characterised in terms of a combination of numerical, statistical and technical capacities. In this article, we argue for an expansion of the concept to include not just competencies in reading and working with datasets but also the ability to account for, intervene around and participate in the wider (...) socio-technical infrastructures through which data is created, stored and analysed – which we call “data infrastructure literacy”. We illustrate this notion with examples of “inventive data practice” from previous and ongoing research on open data, online platforms, data journalism and data activism. Drawing on these perspectives, we argue that data literacy initiatives might cultivate sensibilities not only for data science but also for data sociology, data politics as well as wider public engagement with digital data infrastructures. The proposed notion of data infrastructure literacy is intended to make space for collective inquiry, experimentation, imagination and intervention around data in educational programmes and beyond, including how data infrastructures can be challenged, contested, reshaped and repurposed to align with interests and publics other than those originally intended.

This article aims to provide a brief overview of mental causation problem and its current proposed solutions. Indeed, mental causation turns out as one of the most difficult philosophical conundrums in contemporary philosophy of mind. In the first two sections, we offer an outline of the problem and the philosophical debate about it, and show that mental causation problem is pivotal within the contemporary philosophy of mind. In the third section, we focus on the most popular models of mental causation, (...) namely Kim's and Davidson's accounts, also discussing the objections raised against them. In the final section, we take into consideration some recent proposals poised to solve the mental causation problem, including powerism. Given the logical and metaphysical plausibility of almost all these different options, our conclusion is that mental causation is still an open problem and it is far from being resolved. (shrink)

Soviet Marxism is often characterized by the term ontologism. The latter could be defined as a totalizing assertion about material being as inherently dialectical, often coupled with an understanding of thought as mere reflection. This fundamental assertion is said to remain unchallenged among dogmatic party philosophers and critical Marxists alike. Far from an innocent misconception, Soviet ontologism is associated with some of the harshest historical events like the Lysenko affair, where the imposition of the dialectical optic onto the natural sciences (...) resulted in an ideological blockade of research. Various sources of this peculiarity have been identified in Soviet Marxism, from the endorsement of dialectics of nature to the rejection of Cartesian metaphysics. However, a political account of Soviet ontologism is yet to be written. This article will address the question of ontologism as it has been theorized in relation to the philosophy of Evald Ilyenkov. Tracing the history of Russian ontologism from the nineteenth century, we will recover its nationalist dimension. Then, drawing on the philosophical controversies between Lenin and Bogdanov, which in turn will be linked to Ilyenkov’s intervention, we will examine the various strands of ontological thinking in Soviet Marxism and identify Ilyenkov’s position. Finally, we will ask what insights can the ontological thinking of Soviet Marxism provide in the context of contemporary philosophical turns towards ontology. (shrink)

It is often asserted that a liberal theory of political obligation is unattainable. This is, largely, because liberalism revolves around consent and hence, is supposed to be intrinsically inimical to the existence of state authority. However, there is at least one liberal proposal – the argument of fair play, that makes a plausible case for justifying the establishment of a coercive entity. The most popular contemporary version of it, which is offered by George Klosko, turns on the fact that non-excludable (...) goods cannot be exchanged based on consent. Instead, there must be enforceable, independent, objective standards of fairness that should govern the distribution of the effects of such goods. In this article, I argue that if Klosko’s account is correct, then not only the existence of non-excludable goods but also, the production and exchange of existentially significant excludable goods warrant an establishment of coercive authority. I argue that in this way, we can take an important step towards establishing a full-blown liberal theory of political obligation. (shrink)

The majority of G protein-coupled receptors (GPCRs) self-assemble in the form dimeric/oligomeric complexes along the plasma membrane. Due to the molecular interactions they participate, GPCRs can potentially provide the framework for discriminating a wide variety of intercellular signals, as based on some kind of combinatorial receptor codes. GPCRs can in fact transduce signals from the external milieu by modifying the activity of such intracellular proteins as adenylyl cyclases, phospholipases and ion channels via interactions with specific G-proteins. However, in spite of (...) the number of cell functions they can actually control, both GPCRs and their associated signal transduction pathways are extremely well conserved, for only a few alleles with null or minor functional alterations have so far been found. This would seem to suggest that, beside a mechanism for DNA repairing, there must be another level of quality control that may help maintaining GPCRs rather stable throughout evolution. We propose here receptor oligomerization to be a basic molecular mechanism controlling GPCRs redundancy in many different cell types, and the plasma membrane as the first hierarchical cell structure at which selective categorical sensing may occur. Categorical sensing can be seen as the cellular capacity for identifying and ordering complex patterns of mixed signals out of a contextual matrix, i.e., the recognition of meaningful patterns out of ubiquitous signals. In this context, redundancy and degeneracy may appear as the required feature to integrate the cell system into functional units of progressively higher hierarchical levels. (shrink)

Four research strategies currently employed by mainstream psychologists in researching the experiences and behaviors of human subjects are criticized for diminishing the presence of subjectivity. Two perspectives that tend to exaggerate subjectivity are also criticized. A balanced approach to subjectivity is offered that: acknowledges a theoretical perspective that recognizes that there are invisible or nonsensorial characteristics of subjectivity that have to be theoretically appropriated, and that emphasizes the intersubjective dimension as being critical for properly assessing a balanced approach to human (...) subjectivity. A subject-dependent perspective that can efface its own interests is the attitude that is required for the achievement of objectivity. (shrink)

This work is an attempt to lay foundations for a theory of interactive computation and bring logic and theory of computing closer together. It semantically introduces a logic of computability and sets a program for studying various aspects of that logic. The intuitive notion of computational problems is formalized as a certain new, procedural-rule-free sort of games between the machine and the environment, and computability is understood as existence of an interactive Turing machine that wins the game against any possible (...) environment. The formalism used as a specification language for computational problems, called the universal language, is a non-disjoint union of the formalisms of classical, intuitionistic and linear logics, with logical operators interpreted as certain—most basic and natural—operations on problems. Validity of a formula is understood as being “always computable”, and the set of all valid formulas is called the universal logic. The name “universal” is related to the potential of this logic to integrate, on the basis of one semantics, classical, intuitionistic and linear logics, with their seemingly unrelated or even antagonistic philosophies. In particular, the classical notion of truth turns out to be nothing but computability restricted to the formulas of the classical fragment of the universal language, which makes classical logic a natural syntactic fragment of the universal logic. The same appears to be the case for intuitionistic and linear logics . Unlike classical logic, these two do not have a good concept of truth, and the notion of computability restricted to the corresponding two fragments of the universal language, based on the intuitions that it formalizes, can well qualify as “intuitionistic truth” and “linear-logic truth”. The paper also provides illustrations of potential applications of the universal logic in knowledgebase, resourcebase and planning systems, as well as constructive applied theories. The author has tried to make this article easy to read. It is fully self-contained and can be understood without any specialized knowledge of any particular subfield of logic or computer science.

Dzhaparidze, G., A generalized notion of weak interpretability and the corresponding modal logic, Annals of Pure and Applied Logic 61 113-160. A tree Tr of theories T1,...,Tn is called tolerant, if there are consistent extensions T+1,...,T+n of T1,...,Tn, where each T+i interprets its successors in the tree Tr. We consider a propositional language with the following modal formation rule: if Tr is a tree of formulas, then Tr is a formula, and axiomatically define in this language the decidable logics TLR (...) and TLRω. It is proved that TLR yields exactly the schemata of PA-provable sentences, if Tr is understood as “Tr is tolerant”. In fact, TLR axiomatizes a considerable fragment of provability logic with quantifiers over ∑1-sentences, and many relations that have been studied in the literature can be expressed in terms of tolerance. We introduce and study two more relations between theories: cointerpretability and cotolerance which are, in a sense, dual to interpretability and tolerance. Cointerpretability is a characterization of ∑1-conservativity for essentially reflexive theories in terms of translations. (shrink)

Involutive Stone algebras were introduced by R. Cignoli and M. Sagastume in connection to the theory of $n$-valued Łukasiewicz–Moisil algebras. In this work we focus on the logic that preserves degrees of truth associated to S-algebras named Six. This follows a very general pattern that can be considered for any class of truth structure endowed with an ordering relation, and which intends to exploit many-valuedness focusing on the notion of inference that results from preserving lower bounds of truth values, and (...) hence not only preserving the value $1$. Among other things, we prove that Six is a many-valued logic that can be determined by a finite number of matrices. Besides, we show that Six is a paraconsistent logic. Moreover, we prove that it is a genuine Logic of Formal Inconsistency with a consistency operator that can be defined in terms of the original set of connectives. Finally, we study the proof theory of Six providing a Gentzen calculus for it, which is sound and complete with respect to the logic. (shrink)

The paper gives a soundness and completeness proof for the implicative fragment of intuitionistic calculus with respect to the semantics of computability logic, which understands intuitionistic implication as interactive algorithmic reduction. This concept — more precisely, the associated concept of reducibility — is a generalization of Turing reducibility from the traditional, input/output sorts of problems to computational tasks of arbitrary degrees of interactivity.

O romance A Selva contou com quatro edições ilustradas: A de 1939, coordenada por Roberto Nobre, a de 1949, realizada por Machado da Luz, a de 1955, realizada por Cândido Portinari e uma última em 1974 realizada por Júlio Pomar. A primeira edição ilustrada correspondeu a um projecto de encomenda diferente das edições seguintes, nomeadamente da que serve aqui de termo de comparação, a de Portinari (1955). Roberto Nobre pretendia que oito ilustradores traduzissem picturalmente A Selva a partir de uma (...) geografia imaginária que o livro lhes desse a ver. Sendo a Selva um território estranho para os pintores desta edição, fica deste projecto uma tradução pela ilustração de paisagens sem identidade pictural – lugares brancos no conjunto das edições ilustradas do romance de Ferreira de Castro.

From the phenomenological perspective, intentionality is an important concept for understanding consciousness. The idea was introduced into psychology by Brentano in the 19th century who got it from Scholasticism. Husserl modified its meaning and made it a key concept in his philosophy. This paper shows one way in which intentionality can help clarify psychological phenomena.

En medio de una sociedad que nos invita constantemente a la extroversión, cabe preguntarnos si el encuentro con nosotros mismos a través de una actitud “interior” y reflexiva no puede representar un factor clave para detener, en alguna medida, el proceso de deshumanización que descompone a Occidente.

The paper demonstrates that a detailed analysis of Hegel’s criticism of rationalist metaphysics in the “Vorbegriff” (Preliminary Conception) chapter of the Encyclopedia Logic can shed light on the following critical features of Hegel’s metaphysics: (1) advancing semantic holism as an alternative to semantic atomism; (2) renouncing the projection of a substance-attribute formal structure onto actuality; (3) dismissing sense perception as the source of conceptual content; and (4) rejecting dualist ontology.

El análisis propuesto en este texto señala que, en el proceso de imaginar y hacer posible la nación moderna en la América hispánica, el Libertador Simón Bolívar invocó el origen cívico y revolucionario de los nacientes Estados, y no la uniformidad etnocultural. En este aspecto, su postura fue radicalmente moderna y antigenealógica, en tanto afirmó que la unidad del carácter que supone la nación como comunidad política no tiene que coincidir, necesariamente, con los límites de las nacionalidades. Este artículo toma (...) como referencia el Discurso de Angostura, pronunciado por el Libertador en 1819, para mostrar que, al momento de construir esa gran nación que se debía llamar Colombia, Bolívar apeló a premisas políticas y territoriales, y no a los presupuestos nacionalistas de igualdad lingüística, racial o cultural. En tal sentido, su propuesta constitucional se inscribe en la tradición del patriotismo republicano y el ideal de la nación de ciudadanos. (shrink)

This research characterizes and compares the job satisfaction of fitness professionals in Portugal between genders, ages, professional experience, professional title, and educational qualifications. A total of 401 fitness professionals answered the online questionnaire Job Satisfaction Scale, which has 16 factors rated on a Likert scale with seven levels. The statistical analysis comprises descriptive and statistical tests to compare the results of two (t-test) or more (ANOVA) groups. Overall, the results demonstrated that fitness professionals were moderately satisfied with their work. The (...) lower degrees of job satisfaction were concerning salary, opportunities for promotion, and stability at work. The highest levels of job satisfaction were related to the freedom to choose their work method, their work colleagues, the physical conditions of their workplace, and the opportunity to use their competencies. There were no differences in job satisfaction in terms of gender and a few differences between professional title and between educational levels. Regarding age and professional experience, the results showed significant differences in almost all factors, suggesting that, as fitness professionals get older and more experienced, their job satisfaction is greater. The results of this study suggest that even though fitness professionals are, in general, moderately satisfied with their work, some aspects can be improved by employers to increase their satisfaction levels. Such findings would assist employers in guiding the job satisfaction of their employees with consequent enhancements in the services provided by fitness professionals, which can increase participants’ retention in exercise fitness activities.

Quite a few cognitive scientists are working toward a naturalization of phenomenology. Looking more closely at the relevant literature, however, the ‘naturalizing phenomenology’ proposals show the presence of different conceptions, assumptions, and formalisms, further differentiated by different philosophical and/or scientific concerns. This paper shows that the original Husserlian stance is deeper, clearer and more advanced than most supposed contemporary improvements. The recent achievements of experimental phenomenology show how to ‘naturalize’ phenomenology without destroying the guiding assumptions of phenomenology. The requirements grounding (...) the scientific explanation of subjective experience are discussed, such as the nature of the stimuli, their variables, and their manipulation by properly phenomenological methods.

This article points out the criteria necessary in order for a qualitative scientific method to qualify itself as phenomenological in a descriptive Husserlian sense. One would have to employ description within the attitude of the phenomenological reduction, and seek the most invariant meanings for a context. The results of this analysis are used to critique an article by Klein and Westcott , that presents a typology of the development of the phenomenological psychological method.

This paper presents a soundness and completeness proof for propositional intuitionistic calculus with respect to the semantics of computability logic. The latter interprets formulas as interactive computational problems, formalized as games between a machine and its environment. Intuitionistic implication is understood as algorithmic reduction in the weakest possible — and hence most natural — sense, disjunction and conjunction as deterministic-choice combinations of problems , and “absurd” as a computational problem of universal strength.

In the contemporary scene, psychological researchers seeking alternative research strategies are turning increasingly toward interpretation theory. However, other strategies are also available, and one of these is descriptive science. Descriptive practices as the basis for the clarification of meanings have received less emphasis because of several epistemological assumptions about meaning that have appeared in the literature of interpretive science. Based upon the work of contemporary transcendental philosophers, especially J. N. Mohanty, this article argues that a descriptive scientific perspective can respond (...) to some of the hermeneutic arguments about meaning and that solid findings can be established descriptively. It is argued that both description and interpretation are legitimate but that they are tied to different conditions and interests. (shrink)

Empiricism had dominated scientific activities for about three centuries but beginning with the 20th Century a new philosophy, phenomenology, began to develop and certain scientists who conducted research with humans began to turn to phenomenology as the basis for their scientific work rather than empiricism. What was known as the Utrecht School in Holland just after World War II, psychologists at Duquesne University during mid-twentieth century, pedagogists in Canada at about the same time and nurses later in the twentieth century (...) all began to base their research on phenomenological philosophical principles rather than on empiricism. Certain philosophers criticized the approach of these scientists and offered their own praxis based directly on phenomenological philosophy. However, one of the members of the Duquesne University’s group strongly criticized the evaluation of his approach by the philosophers and demonstrated the significant errors of their criticism. The psychologist then clarified his scientific phenomenological approach toward psychological phenomena and emphasized the role of the phenomenological epoche’ and reduction for Husserlian scientific phenomenology.

This book considers the semantic and syntactic nature of indexicals - linguistic expressions, as in I, you, this, that, yesterday, tomorrow , whose reference shifts from utterance to utterance.There is a long-standing controversy as to whether the semantic reference point is already present as syntactic material or whether it is introduced post-syntactically by semantic rules of interpretation. Alessandra Giorgi resolves this controversy through an empirically grounded exploration of temporal indexicality, arguing that the speaker's temporal location is specified in the syntactic (...) structure. She supports her analysis with theoretical and empirical arguments based on data from English, Italian, Chinese, and Romanian. Professor Giorgi addresses some difficult and longstanding issues in the analysis of temporal phenomena - including the Italian imperfect indicative, the properties of the so-called future-in-the-past, and the properties of Free Indirect Discourse - and shows that her framework can account elegantly for all of them. Carefully argued, succinct, and clearly written her book will appeal widely to semanticists in linguistics and philosophy from graduate level upwards and to linguists interested in the syntax-semantics interface.

This book presents an historical and conceptual reconstruction of the theories developed by Meinong and a group of philosophers and experimental psychologists in Graz at the turn of the 19th century. Adhering closely to original texts, the contributors explore Meinong's roots in the school of Brentano, complex theories such as the theory of intentional reference and direct reference, and ways of developing philosophy which are closely bound up with the sciences, particularly psychology. Providing a faithful reconstruction of both Meinong's contributions (...) to science and the school that arose from his thought, this book shows how the theories of the Graz school raise the possibility of engaging in the scientific metaphysics and ontology that for so long have been considered off limits.

Defining a class of sets to be uniform Δ02 if it is derived from a binary {0,1}{0,1}-valued function f≤TKf≤TK, we show that, for any C⊆DeC⊆De induced by such a class, there exists a high Δ02 degree c which is incomparable with every degree b ϵ Ce \ {0e, 0'e}. We show how this result can be applied to quite general subclasses of the Ershov Hierarchy and we also prove, as a direct corollary, that every nonzero low degree caps with both (...) a high and a nonzero low Δ02 degree.

Experimental phenomenology is the study of appearances in subjective awareness. Its methods and results challenge quite a few aspects of the current debate on consciousness. A robust theoretical framework for understanding consciousness is pending: current empirical research waves on what a phenomenon of consciousness properly is, not least because the question is still open on the observables to be measured and how to measure them. I shall present the basics of experimental phenomenology and discuss the current development of experimental phenomenology, (...) its main features, and the many misunderstandings that have obstructed a fair understanding and evaluation of its otherwise enlightening outcomes.
