We make use of a Theorem of Burris-McKenzie to prove that the only decidable variety of diagonalizable algebras is that defined by 0=1. Any variety containing an algebra in which 01 is hereditarily undecidable. Moreover, any variety of intuitionistic diagonalizable algebras is undecidable.

I give several characterizations of the set V₀ proposed in [3] as the set of meaningful and true sentences of first order arthimetic, and show that in Peano arithmetic the Σ₂ completeness of V₀ is provable.

This paper treats a kind of a modal logic based on the intuitionistic propositional logic which arose from the provability predicate in the first order arithmetic. The semantics of this calculus is presented in both a relational and an algebraic way.Completeness theorems, existence of a characteristic model and of a characteristic frame, properties of FMP and FFP and decidability are proved.

If the laws of nature are as the Humean believes, it is an unexplained cosmic coincidence that the actual Humean mosaic is as extremely regular as it is. This is a strong and well-known objection to the Humean account of laws. Yet, as reasonable as this objection may seem, it is nowadays sometimes dismissed. The reason: its unjustified implicit assignment of equiprobability to each possible Humean mosaic; that is, its assumption of the principle of indifference, which has been attacked on (...) many grounds ever since it was first proposed. In place of equiprobability, recent formal models represent the doxastic state of total ignorance as suspension of judgment. In this paper I revisit the cosmic coincidence objection to Humean laws by assessing which doxastic state we should endorse. By focusing on specific features of our scenario I conclude that suspending judgment results in an unnecessarily weak doxastic state. First, I point out that recent literature in epistemology has provided independent justifications of the principle of indifference. Second, given that the argument is framed within a Humean metaphysics, it turns out that we are warranted to appeal to these justifications and assign a uniform and additive credence distribution among Humean mosaics. This leads us to conclude that, contrary to widespread opinion, we should not dismiss the cosmic coincidence objection to the Humean account of laws. (shrink)

Certain results, most famously in classical statistical mechanics and complex systems, but also in quantum mechanics and high-energy physics, yield a coarse-grained stable statistical pattern in the long run. The explanation of these results shares a common structure: the results hold for a 'typical' dynamics, that is, for most of the underlying dynamics. In this paper I argue that the structure of the explanation of these results might shed some light --a different light-- on philosophical debates on the laws of (...) nature. In the explanation of such patterns, the specific form of the underlying dynamics is almost irrelevant. The conditions required, given a free state-space evolution, suffice to account for the coarse-grained lawful behaviour. An analysis of such conditions might thus provide a different account of how regular behaviour can occur. This paper focuses on drawing attention to this type of explanation, outlining it in the diverse areas of physics in which it appears, and discussing its limitations and significance in the tractable setting of classical statistical mechanics.

Den einen gilt Nietzsche als Verfasser blendender Aphorismen, in denen zu fast allen Themen kritische bis zynische Pointen zu finden sind, andere schatzen und ehren in ihm den systematischen Denker, dessen Relevanz fur die Geistesgeschichte des 20. Jahrhunderts kaum zu uberschatzen ist. Die vorliegende Studie zeigt, dass aphoristische wie systematische Aspekte Ausdruck eines Forschungsprogramms sind, welches Nietzsche als historische Philosophie bzw. historisches Philosophieren bezeichnet und praktiziert hat. Die im Werk verstreuten und bislang nicht systematisch ausgewerteten richtungweisenden Formulierungen werden umfassend aufgearbeitet.

El término nuestroamericano —utilizado por Horacio Cerutti— tiene sus fundamentos en el concepto "Nuestra América". Este hilo conductor de pensamiento tiene como hecho ineludible el hacerse cargo de la realidad en que se vive y del lugar en donde se está, hecho expresado en un permanente interés en la identidad cultural y nacional, como también por una lectura crítica y explicativa del desarrollo de las ideas. En el caso de Chile, a nuestro juicio, la memoria filosófica nuestroamericana ha tendido a (...) ser borrada, olvidada, siendo obnubilada por un fuerte eurocentrismo, lo que ha dado como resultado un escaso número de filósofos preocupados por "lo latinoamericano". Así, este trabajo indaga sobre los orígenes de la vertiente latinoamericanista en la filosofía chilena en la segunda mitad del siglo XX. A modo de conclusión, proponemos que no es sino hasta los años ochenta cuando, desde el Círculo de Filosofía de la Academia de Humanismo Cristiano, se genera un punto de inflexión con la tradición filosófica chilena, dando origen de forma más nítida a la vertiente nuestroamericana que, antes de esto, solo habría tenido pequeñas huellas dispersas.

Der Kern der Denkleistung Schellings kann als der fortgesetzte Versuch umschrieben werden, einen absoluten Anfang, den Ursprung, zu denken. Nach Schellings eigener Meinung ist die Losung dieser Aufgabe in seinen Weltalter-Texten erstmals formuliert. Hier liegt der Schlussel zum Verstandnis des spaten Schelling, vielleicht der ganzen Philosophie Schellings.

Measurement is a process aimed at acquiring and codifying information about properties of empirical entities. In this paper we provide an interpretation of such a process comparing it with what is nowadays considered the standard measurement theory, i.e., representational theory of measurement. It is maintained here that this theory has its own merits but it is incomplete and too abstract, its main weakness being the scant attention reserved to the empirical side of measurement, i.e., to measurement systems and to the (...) ways in which the interactions of such systems with the entities under measurement provide a structure to an empirical domain. In particular it is claimed that (1) it is on the ground of the interaction with a measurement system that a partition can be induced on the domain of entities under measurement and that relations among such entities can be established, and that (2) it is the usage of measurement systems that guarantees a degree of objectivity and intersubjectivity to measurement results. As modeled in this paper, measurement systems link the abstract theory of measuring, as developed in representational terms, and the practice of measuring, as coded in standard documents such as the International Vocabulary of Metrology.

This is a title on the foundations of defeasible logic, which explores the formal properties of everyday reasoning patterns whereby people jump to conclusions, reserving the right to retract them in the light of further information. Although technical in nature the book contains sections that outline basic issues by means of intuitive and simple examples. This book is primarily targeted at philosophers interested in the foundations of defeasible logic, logicians, and specialists in artificial intelligence and theoretical computer science.

In this paper we aim to show an intrinsic contradiction of contemporary Metaphysical Realism by focusing on the relation between the subject and the object. Metaphysical Realism considers facts and objects as being empirical, and therefore they are considered in relation to the subject, while at the same time facts are assumed to belong to an autonomous and independent reality. However, if a real object is considered to be independent from the subject, once it enters in a relation with the (...) latter, a real object must undergo an intrinsic transformation. However, since an object cannot avoid this transformation then recovering the real or “absolute” object from the perceived object is not possible. In this way, the inherent contradiction of the “absolute” as being determined, i.e., defined by virtue of a limit, is revealed. (shrink)

Can stable regularities be explained without appealing to governing laws or any other modal notion? In this paper, I consider what I will call a ‘Humean system’—a generic dynamical system without guiding laws—and assess whether it could display stable regularities. First, I present what can be interpreted as an account of the rise of stable regularities, following from Strevens [2003], which has been applied to explain the patterns of complex systems (such as those from meteorology and statistical mechanics). Second, since (...) this account presupposes that the underlying dynamics displays deterministic chaos, I assess whether it can be adapted to cases where the underlying dynamics is not chaotic but truly random—that is, cases where there is no dynamics guiding the time evolution of the system. If this is so, the resulting stable, apparently non-accidental regularities are the fruit of what can be called statistical necessity rather than of a primitive physical necessity. (shrink)

Due programmi diversi si intersecano nel lavoro di Frege sui fondamenti dell’aritmetica: • Logicismo: l’aritmetica `e riducibile alla logica; • Estensionalismo: l’aritmetica `e riducibile a una teoria delle estensioni. Sia nei Fondamenti che nei Principi, Frege articola l’idea che l’aritmetica sia riducibile a una teoria logica delle estensioni.

Con base en el sentido histórico de Zaratustra, se examina un problema que atraviesa toda la tradición, el problema de los dualismos, es decir, la explicación filosófica que tiende a la escisión o, en otras palabras, el planteamiento de una separación radical del todo en elemen tos (alma-cuerpo, sujeto-objeto, verdad-falsedad y así sucesivamente). No se investigan algunos dualismos, sino que se expone la dualidad como origen de las reflexiones dualistas y plantea cómo es que, más bien, es posible dar razón (...) de los dualismos mediante la unidad.

This paper aims to support the claim that analytic metaphysics should be more cautious regarding the constraints that truthmaking considerations impose on metaphysical theories. To this end, I reply to Briggs and Forbes (2017), whoargue that certain truthmaking commitments are incurred by a Humean metaphysics and by the Growing-Block theory. First, I argue that Humean Supervenience does not need to endorse a standard version of truthmaker maximalism. This undermines Briggs and Forbes’s conclusion that Humean Supervenience and the Growing-Block theory are (...) incompatible. Second, I argue that the Growing-Block theory does not commit us to any weaker version of truthmaker maximalism, which also undermines Briggs and Forbes’s conclusion. Finally, I point out other reasons to think that any version of truthmaker maximalism is disputable, undermining a fortiori Briggs and Forbes’s conclusion and supporting the moral that metaphysical theories—or at least Humean Supervenience, the Growing-Block theory, and presentism—are little constrained by truthmaking commitments.

The purpose of this article is studying An Answer to the Question: ‘What is Enlightenment?’ by Immanuel Kant —a renowned text in the field of philosophy— assuming the dimension of the public as a central piece of analysis. In order to do that, the lectures of Michel Foucault on the same text are presented in the first place. Second, the diagram formed by the terms öffenlicht and Publikum is approached by pointing out their articulating elements and the tensions produced from (...) their different uses. Finally, the uses and senses of what is public are reflected upon, while trying to characterize the current model of political rationality. This mutual operationalization between the uses of the public in the text is noticeable as a particularly relevant and pertinent instance to evaluate diverse processes and phenomena, all related to the problem of government in its political dimension.

Este trabajo avanza la tesis de que los estudios de gubernamentalidad se han definido por la ausencia de un perímetro o dominio concerniente al poder político para realizar sus análisis. Lo han hecho por la sencilla razón de que se trata de un fenómeno interior a las mismas artes de gobierno. Y esto, lejos de obstaculizar el estudio de las complejas formas de conducción de conductas y el papel de las instancias estatales, privadas, o comunitarias en ellas, comporta la ventaja (...) de realizar un diagnóstico a partir de la inmanencia de sus propios modos de inteligir lo real. Para dar cuenta de esto, propongo una lectura sujeta a estos objetivos de las principales apuestas analíticas involucradas en el enfoque. Concluyo exponiendo brevemente que la diferencia específica de los estudios de gubernamentalidad ya no radica tanto en la propuesta explícita y puntual respecto a la forma de entender al estado (no es uno, no tiene esencia, etc.) sino en el movimiento que consiste en atribuir a las artes de gobierno sus propias escalas de poder político. Es aquí donde el enfoque sobre las artes gubernamentales se distancia de buena parte de los proyectos de teoría y filosofía política imperantes a comienzos del siglo XXI, aún en pugna en las altas cumbres de las definiciones.

We extend the deceptive advertising model of Piccolo et al. :611–624, 2015) to a framework in which consumers may be loss averse. There are two sellers, competing on prices and offering experience goods with some differences in quality. Prospective customers may be harmed by deceptive advertising: a marketing practice that can induce them to make bad purchases. We show that although deceptive advertising occurs depending on the degree of consumers’ loss aversion, this behavioral bias does not reflect on firms’ prices. (...) Nevertheless, the presence of loss-averse consumers crucially changes the optimal deterrence rule that a Public Authority should adopt against false claims and misleading advertising. Unlike Piccolo et al., in this more general model, strong enforcements may improve the buyer welfare according to the degree of loss aversion. (shrink)

Universities have long been involved in knowledge transfer activities. Yet the last 30 years have seen major changes in the governance of university–industry interactions. Knowledge transfer has become a strategic issue: as a source of funding for university research and (rightly or wrongly) as a policy tool for economic development. Universities vary enormously in the extent to which they promote and succeed in commercializing academic research. The identification of clear-cut models of governance for university–industry interactions and knowledge transfer processes is (...) not straightforward. The purpose of this article is to critically discuss university knowledge transfer models and review the recent developments in the literature on research collaborations, intellectual property rights and spin-offs, those forms of knowledge transfer that are more formalized and have been institutionalized in recent years. The article also addresses the role played by university knowledge transfer organizations in promoting commercialization of research results. (shrink)

Anhand historischer und quellenkritischer Untersuchungen analysiert das Buch entscheidende Momente des Verhältnisses von Kunst und Wissenschaft in Nietzsches Werk. Zum Leitmotiv der vorgeschlagenen Interpretation wird die Idee einer "Tragödie der Erkenntnis" als Vervollständigung der ästhetischen Tragödie. Aldo Venturelli beleuchtet damit auch Aspekte von Nietzsches besonderer Stellung im philosophischen Diskurs der Moderne.

Human coalitions frequently persist through multiple, overlapping membership generations, requiring new members to cooperate and coordinate with veteran members. Does the mind contain psychological adaptations for interacting within these intergenerational coalitions? In this paper, we examine whether the mind spontaneously treats newcomers as a motivationally privileged category. Newcomers—though capable of benefiting coalitions—may also impose considerable costs (e.g., they may free ride on other members, they may be poor at completing group tasks). In three experiments we show (1) that the mind (...) categorizes coalition members by tenure, including newcomers; (2) that tenure categorization persists in the presence of orthogonal and salient social dimensions; and (3) that newcomers elicit a pattern of impressions consistent with their probable ancestral costs. These results provide preliminary evidence for a specialized component of human coalitional psychology: an evolved concept of newcomer. (shrink)

Este artigo apresenta uma abordagem inicial sobre a caracterização do campo meta-teórico de pesquisa em educação inclusiva e, em particular, examina as forças que produzem seu discurso na pesquisa documental. É reconhecida a necessidade de avançar na exploração de uma perspectiva epistêmica que permita superar o absentismo teórico enfrentado pela educação inclusiva em tempos complexos. O desenvolvimento atual da pesquisa em educação inclusiva é alimentado por vários campos de confluência fora da pedagogia, o que resultou na cristalização de um discurso (...) crítico e não crítico sobre si mesmo. As diferenças entre as perspectivas crítica e acrítica residem na ausência de raciocínio para politizar a discussão sobre a inclusão como mecanismo de transformação de todos os campos da vida do cidadão. Isso confirma a presença de políticas de produção de conhecimento que impõem fundamentos intelectuais binários e poucos pontos de fuga para problematizar as relações estruturais da desigualdade. Soma-se a isso as fortes raízes de padrões que impõem modelos epistêmicos quebrados para pensar nas opressões objeto das diversas identidades que chegam ao espaço escolar e demarcam novas formas de expressão cidadã. Conclui-se com base em um modelo pré-construído de tipo normativo para refletir sobre as questões fundamentais do desenvolvimento humano e cidadão. É necessário promover um processo de descolonização em todos os campos da Ciência da Educação, bem como uma crítica genealógica dos fundamentos híbridos que este modelo propõe, dada a uniformidade de seu discurso em todos os ciclos e níveis de ensino. Palavras-chave: educação inclusiva, políticas de produção de conhecimento, epistemologia, identidades e temas educacionais. (shrink)

A compreensão epistemológica da Educação Inclusiva expressa um funcionamento diaspórico, isto é, as formas de construção do seu conhecimento, operam através de uma dispersão do conhecimento, distribuída por uma multiplicidade de geografias epistêmicas, entre elas, Feminismo, Teoria Queer, Estudos Postcolonial, entre outros. Neste caso, as contribuições do Feminismo e dos Estudos Queer, tornam-se instâncias chave do conhecimento para promover a proposta de uma nova racionalidade - cada vez mais ampla em suas propostas e sistemas de raciocínio - para justificar a (...) relevância da inclusão para além da produção de ficções baseadas na inclusão no mesmo - dentro da Ciência da Educação no século XXI. Retornando à idéia de Educação Inclusiva como "categoria de análise" e "dispositivo macroeducativo", esta entrevista analisa as interseções políticas, epistêmicas e pedagógicas que a Pedagogia Queer compartilha com a Educação Inclusiva; reconhecendo o primeiro como uma das suas principais memórias epistêmicas de transformação. Nessa ocasião, o Dr. Nilson Dinis, acadêmico do Departamento de Educação e Não-Programa de Graduação em Educação da Universidade Federal de São Carlos, nos dá reflexões interessantes sobre a configuração de um campo que, embora exprima uma longa história em epistemologias subalternas, é conhecida e entendida a partir de uma posição de afastamento e periferia na educação e no treinamento de professores. O Dr. Dinis também aprofunda a compreensão do trans, sua agência e repercussões políticas nas gramáticas educacionais. Ao mesmo tempo, dá idéias-chave para abordar o currículo, as lógicas operacionais das instituições educacionais e a co-gestão das identidades sexuais no contexto educacional. Indubitavelmente, suas contribuições contribuem para posicionar um tópico que as políticas públicas e educacionais no campo da produção de Educação Inclusiva, é subalternizado, gerando novas estratégias de apartheid do conhecimento ou em termos de Spivak ou Foucault, a violência epistêmica, se tornam os chamados "vazios da diversidade", que são apenas declarações que atraem a noção de diferença para o centro do capitalismo, sem abordá-lo, deixando-o em uma situação permanente de desvalorização social e indefesa. Em suma, a entrevista espelha uma crescente complexidade, convidando-nos a superar as simplicidades pedagógicas a este respeito. Palavras-chave: pedagogia queer, educação inclusiva, multiplicidade de diferenças, ação e resistência política. (shrink)

El artículo examina el sentido de la metafísica a partir de Kant. El objetivo no es desmenuzar cada una de las determinaciones que el filósofo ofrece, toda vez que describe tanto el quehacer de la tradición como el suyo propio, sino revisar en qué consiste la posibilidad de esa diferencia —y unidad— entre la metafísica tradicional y la kantiana. El énfasis yace, por tanto, en la historicidad de la filo- sofía kantiana de acuerdo con algunos conceptos fundamentales.

El presente ensayo ofrece algunas meditaciones en torno a lo que representan la lengua y la patria para la filosofía. Estas reflexiones son motivadas por la publicación, en este número de Estudios, de los Ensayos del catalán de Eduardo Nicol, filósofo que se vio obliga do a elaborar su obra no solo desde el exilio de su patria, sino en una lengua, hasta cierto punto, extranjera. El objetivo, no obstante, no es plantear las correspondientes preguntas desde un ángulo nacionalista particular, (...) sino desde uno universal metafísico, quehacer al que Nicol se consagró a lo largo de toda su obra.

In our paper, monadic modal pseudocomplemented De Morgan algebras are considered following Halmos’ studies on monadic Boolean algebras. Hence, their topological representation theory is used successfully. Lattice congruences of an mmpM is characterized and the variety of mmpMs is proven semisimple via topological representation. Furthermore and among other things, the poset of principal congruences is investigated and proven to be a Boolean algebra; therefore, every principal congruence is a Boolean congruence. All these conclusions contrast sharply with known results for monadic (...) De Morgan algebras. Finally, we show that the above results for mmpM are verified for monadic tetravalent modal algebras.

It is not uncommon in the history of science and philosophy to encounter crucial experiments or crucial objections the truth-value of which we are ignorant, that is, about which we suspend judgment. Should we ignore such objections? Contrary to widespread practice, I show that in and only in some circumstances they should not be ignored, for the epistemically rational doxastic attitude is to suspend judgment also about the hypothesis that the objection targets. In other words, suspension of judgment “propagates” from (...) the crucial objection to the hypothesis. In this paper I study under which conditions this phenomenon occurs, and discuss its significance for the topics of skepticism, scientific realism, and peer disagreement. (shrink)

The purpose of this note is to acknowledge a gap in a previous paper — “The Complexity of Revision”, see [1] — and provide a corrected version of argument.

Insurgent Universality offers a novel attempt to access history through a problematisation of the notion of universalism. Its main argument is based on three notions articulated in revolutionary events: temporalities, universality and insurgency. In this article we review their theoretical aspects, comment on their limitations, and outline potential reformulations.

In situations where we ignore everything but the space of possibilities, we ought to suspend judgment—that is, remain agnostic—about which of these possibilities is the case. This means that we cannot sum our degrees of belief in different possibilities, something that has been formalized as an axiom of non-additivity. Consistent with this way of representing our ignorance, I defend a doxastic norm that recommends that we should nevertheless follow a certain additivity of possibilities: even if we cannot sum degrees of (...) belief in different possibilities, we should be more confident in larger groups of possibilities. It is thus shown that, in the type of situation considered (in so-called ‘classical ignorance’, i.e. “behind a thin veil of ignorance”), it is epistemically rational for advocates of suspending judgment to endorse this comparative confidence; while on the other hand it is shown that, even in classical ignorance, no stronger belief—such as a precise uniform probability distribution—is warranted.
