In this paper we will review the history of Quechua in the Peruvian territory (including the eras of the Inca empire, the viceroyalty, and the republic) and consider the challenges it faces in order to survive from the bicentenary of our republic onwards. I begin by showing that most varieties of Quechua are in a process of extinction and reflect on the causes that may have determined this trend in the republican era. I defend the thesis that it was the (...) progressive increase in opportunities for social mobility in the republic that motivated an increasing adoption of Spanish by Quechua speakers, since such opportunities depended on mastering Spanish. The paper closes by discussing about the possibilities to reverse the trend towards the extinction of Quechua. (shrink)

In the course of this article we discussed the method of applying philosophy to adolescents, we count on the added experience during the year we worked in a technical college. We have chosen to apply a method that goes beyond the traditional, in order to make the philosophical act more natural and close to the students. We discuss the effectiveness of the traditional while showing the results achieved in this period. We worked with young people from fifteen to nineteen years, (...) these had their focus to learn the agricultural technical part, our challenge was to take philosophy to a group of students who had no real interest in the material, even thought it was useless. Thinking about the difficulties that it was to bring philosophical thought to these young people, together with the problems that are already part of the school, the different social contexts of the students, we developed classes and contents in order to work all these factors. We want to make these young people not simply knowledgeable of the concepts, but rather to broaden their worldview and logical thinking. (shrink)

This paper deals with a relatively recent trend in the history of analytic philosophy, philosophical logic, and theory of science: the philosophical study of the role of inconsistency in empirical science. This paper is divided in three sections that correspond to the three types of inconsistencies identified: (i) factual, occurring between theory and observations, (ii) external, occurring between two mutually contradictory theories, and (iii) internal, characterising theories that entail mutually contradictory statements.

Comments on the paper: Pluralismo y absolutismo en la crítica. Dialéctica reflexiva y política democrática a partir de M. Horkheimer y Th. W. Adorno, by Emiliano Matías Gambarotta.

El documento expone los antecedentes sugeridos por Paul Ricoeur sobre lo que podría denominarse “la polémica epistemológica en ciencias sociales”, referidos a la formulación de un método legítimo para la investigación en dichas ciencias que responda a las particularidades propias de su objeto de estudio. En este sentido, se rastrea la cuestión en la tradición hermenéutica romántica, concretamente en el pensamiento de Wilhelm Dilthey, pasando por la teoría estructural de estudio del texto escrito y la formulación de una teoría de (...) la acción anglosajona, para finalmente terminar en la ricoeurtiana consideración hermenéutica de la acción significativa, que asume al texto como paradigma y propuesta de superación de los escollos en torno a la referida polémica.

The standard definition of “argument” is satisfied by any series of statements in which one (of the statements) is marked as the conclusion of the others. This leads to the counter-intuitive result that “I like cookies, therefore, all swans are white” is an argument, since “therefore” marks “all swans are white” as the conclusion of “I like cookies”. This objection is often disregarded by stating that, although the previous sequence is an argument, it fails to be a good one. However, (...) when we compare our previous argument with a definitely bad argument like “this swan is white, therefore, all swans are white”, we see that there is an important difference between them. Whereas the former fails to fulfil our intuition of what an argument is, the latter does qualify as an argument, but as a bad one. In this talk, I will sketch a definition that better captures this feature of our intuition of what an argument is in three steps. Following Díez and Moulines (1999), I first reduce inductive validity to deductive validity through what we may call the method of deductivisation. Second, through epistemic predicates (cf. Thompson 2002), I introduce a broader concept of validity that accounts not only for deductive and inductive validity, but also for a weaker type of validity that may be called pseudo-validity. I show that these pseudo-valid arguments can also be deductivised with the help of the above-mentioned epistemic predicates. Finally, I re-define the concept of argument as any series of statements that is at least pseudo-valid, which leaves the “cookies argument” outside of this definition. (shrink)

This paper discusses the logical possibility of testing inconsistent empirical theories. The main challenge for answering this affirmatively is to avoid that the inconsistent consequences of a theory both corroborate it and falsify it. I answer affirmatively by showing that we can define a class of empirical sentences whose truth would force us to abandon such inconsistent theory: the class of its potential rejecters. Despite this, I show that the observational contradictions implied by a theory could only be verified (provided (...) we make some assumptions), but not rejected. From this, it follows that, although inconsistent theories are rejectable, they cannot be rejected qua inconsistent. (shrink)

Popper restricted his definition of falsifiability to consistent theories through what we may call his requirement of consistency. His main argument was that an inconsistent theory does not distinguish the sentences that corroborate it from those that contradict it, for all sentences follow from it. I propose to replace this requirement by the more basic requirement that the classes of potential corroborators and falsifiers of a theory do not overlap. This results not only in an unrestricted definition of falsifiability but (...) also in some inconsistent theories being falsifiable whenever that inconsistency is not located among its observational statements. Although this assumes a restriction of the principle of explosion or ex contradictione sequitur quodlibet (ECQ), it does not depend on any particular system or approach of paraconsistent logic. Finally, I propose to define the class of potential refuters of a theory, which is obtained by subtracting the class of potential corroborators from the class of potential falsifiers. Given that, by definition, the classes of potential refuters and corroborators of a theory do not overlap, it immediately follows that some observationally inconsistent theories are refutable in this sense. This establishes the bases for a new and more general formal theory of falsifiability of scientific factual/empirical theories. (shrink)

In this paper I formalise the falsificationist proposal omitting Popper’s requirement of consistency. This omission results in (i) trivial theories being falsifiable in an inappropriate sense of the term, but also in (ii) some inconsistent non-trivial theories being so in an appropriate one. This justifies a slight alteration of the definition of falsifiability that excludes (i) but allows (ii). Instead of requiring that a falsifiable theory be consistent, my proposal only requires that the intersection of its classes of potential corroborators (...) and falsifiers be empty. (shrink)

According to falsificationism, a theory is scientific if it can be incompatible with some empirically testable statements. This epistemological approach has been criticized because, in practice, it is impossible to decide when a particular fact should be considered incompatible with a theory. These criticisms, however, neglect the fact that the Popperian sense of falsification is a “logical sense.” Thus, the Popperian criterion of falsifiability only requires that, assuming certain auxiliary hypotheses, the theory in question be logically incompatible with some empirically (...) testable statements. This paper presents a reassessment of these criticisms, justifying that the criterion of falsifiability is unrenounceable insofar as our best theories should aspire to satisfy it. (shrink)

In this paper, I study the relation between arguments against the person (aka ad hominem or personal attack arguments) and disqualifications for conflicts of interests. I show that both types of arguments share a similar logical structure and that they can be considered to be acceptable in similar circumstances.

This is the story of how the noble squire Sancho Panza, while governing what he thought to be an insula, ingeniously solved a paradox not unlike those of modern logic.

From the apparently trivial problem of homonyms, I argue that proper names as they occur in natural languages cannot be characterised as strings of sounds or characters. This entails, first, that the proper names philosophers talk about are not physical entities, like strings, but abstractions that, second, may be better characterised as triples (s, m, C), where s is the string that conveys the meaning m in a set of contexts C. Third, the generality principle of compositionality may be put (...) into question, for apparently its converse holds in some cases. Finally, the prominence of context for determining the meaning expressed by a sign suggests a strong connection between proper names and indexicals. This connection has been largely overlooked by the analytic tradition, in spite that both proper names and indexicals have been among their hottest topics. This may be because the analytic literature about proper names has been decisively influenced by Frege’s work, which was better suited for formal languages. Izydora Dąmbska and Jerzy Pelc, with their semiotic background, were able to have a finer understanding of this quasi-indexical character of proper names. (shrink)

The possibility of testing contradictory statements about the factual world has been suggested but barely discussed in the relevant literature. Here I argue that if we assume that there are contradictory observation sentences, it would be logically impossible to falsify them. Accordingly, the extension of the dialetheist programme into empirical science would be non-advisable, for it would introduce logically unfalsifiable claims.

In this paper, I generalise the logical concept of compatibility into a broader set-theoretical one. The basic idea is that two sets are incompatible if they produce at least one pair of opposite objects under some operation. I formalise opposition as an operation ′ ∶ E → E, where E is the set of opposable elements of our universe U, and I propose some models. From this, I define a relation ℘U × ℘U × ℘U^℘U, which has (mutual) logical compatibility (...) as its more natural interpretation. (shrink)

A non-embracing consequence relation is one such that no set of wffs closed under it is equal to the set of all wffs. I prove that these relations have no deductive power if they are also extensive and monotonic.

This dissertation offers a proof of the logical possibility of testing empirical/factual theories that are inconsistent, but non-trivial. In particular, I discuss whether or not such theories can satisfy Popper's principle of falsifiablility. An inconsistent theory Ƭ closed under a classical consequence relation implies every statement of its language because in classical logic the inconsistency and triviality are coextensive. A theory Ƭ is consistent iff there is not a α such that Ƭ ⊢ α ∧ ¬α, otherwise it is inconsistent. (...) We say, instead, that Ƭ is non-trivial iff there is at least one α such that Ƭ ⊢ α, otherwise we say that it trivial. This happens because classical logic satisfies the principle of explosion, according ex contradictione sequitur quodlibet (from a contradiction anything follows). Under these conditions inconsistent classical theories would be compatible with any well-formed formula, which makes them useless for science. There are, however, so-called paraconsistent logics in which the principle of explosion does not generally hold and in which a theory can be (simply) inconsistent, but also absolutely consistent. It is in this logical framework that we can prove that some inconsistent theories can be falsifiable. (shrink)

Logic systems that can handle contradictions were being used for some time without having a general technical name. One of the main proposers of these systems, Newton da Costa, asked Francisco Miró Quesada to suggest him a name for those systems. In the historical letter that here we translate into English for the first time, Miró Quesada suggests three names to da Costa for this purpose: ‘ultraconsistent’, ‘metaconsistent’, and ‘paraconsistent’; explaining their pros and cons. -/- Paper based on a letter (...) by Francisco Miró Quesada Cantuarias to Newton da Costa, edited, translated, and annotated by Luis Felipe Bartolo Alegre.

In this historical article, Newton da Costa discusses Francisco Miró Quesada’s philosophical ideas about logic. He discusses the topics of reason, logic, and action in Miró Quesada’s work, and in the final section he offers his critical view. In particular, he disagrees with Miró Quesada’s stance on the historicity of reason, for whom “reason is essentially absolute”, whereas for da Costa it “is being constructed in the course of history”. Da Costa concludes by emphasizing the importance of Miró Quesada’s theory (...) of logic and reason, despite it still being incomplete. -/- Historical article by Newton da Costa, annotated and translated by J.

En el presente artículo me aproximo a la relación que guarda el marxismo y la democracia con la idea de justicia que sostuvo el filósofo hispano-mexicano Adolfo Sánchez Vázquez. Para ello me serviré de algunas de sus principales obras pero sobre todo de sus escritos menores, porque en ellos se vislumbra de mejor manera la concepción de justicia del filósofo y se evidencia la estrecha relación de ésta con presupuestos marxistas y socialistas. Para llevar a cabo esta labor será (...) también importante considerar su vida así como situarlo en su contexto, es decir, tener en cuenta desde su experiencia en la guerra civil española hasta su exilio y vida en el México de la segunda mitad del siglo XX. // In this article I approach the issue of the relationship between marxism, democracy, and the idea of justice held by the Hispanic-Mexican philosopher Adolfo Sánchez Vázquez. For doing this, I will take into account some of his main works, but even more I will consider his minor works because they glimpse in a better way his conception of justice, and show the close relationship between such conception and the Marxist and socialist tenets. To do this it will be also important to consider both Sánchez Vázquez’s life and his context, that is, take into consideration since his experience in the Spanish Civil war to his exile in Mexico in the second half of the 20th century.

Los desencuentros de la filosofía latinoamericana con Nietzsche pueden entenderse como un sínto-ma de algo más que un problema de legibilidad o malentendido. En tanto pensamiento de lo uno, la filosofía latinoamericana (mayoritaria) no puede servirse del pensamiento nietzscheano: es imposi-ble construir un pensamiento del origen y la unidad desde un pensamiento de lo múltiple, como el de Nietzsche. La identidad, tan buscada por esa filosofía latinoamericana mayoritaria, es una ansiedad antigenealógica. En ese sentido, esa filosofía y su procedencia no (...) es solo eurocéntrica, como ya ha sido expuesto por otros comentaristas, sino reactiva, y esto vale para tres de sus tendencias principa-les: la filosofía normalizadora, la corriente historicista y la filosofía latinoamericana de la liberación. De ahí, de paso, la fascinación de dicho pensamiento con la idea de carencia —nunca hemos sido lo suficientemente civilizados—. Esto ha instaurado un cuerpo sufriente en América Latina, atrapado en la dialéctica de la víctima y el victimario. Se trata entonces de pensar con Nietzsche para intentar pensar sin resentimiento desde América Latina y sobre esta. ¿Nietzsche en América Latina? Sí, pero más allá de los estudios de recepción e influencia: Nietzsche como aquel estruendo capaz de infundirle una dimensión geológica al pensamiento. -/- . (shrink)

Las relaciones entre Nietzsche y América Latina están marcadas por el desencuentro. Lo cual no implica que Nietzsche no haya sido leído en Latinoamérica; pero es diferente aludir a Nietzsche, a asumir una perspectiva nietzscheana. Por eso, en vez de usar a Nietzsche para analizar su moral, para desplazar el punto de vista, en América Latina se moraliza a Nietzsche al ponerlo al servicio de esa moral, dejándola indemne. El caso de la filosofía latinoamericana es síntoma de ese desencuentro: en (...) tanto pensamiento de lo uno, no puede servirse del pensamiento nietzscheano, ya que es imposible construir un pensamiento del origen y la unidad desde un pensamiento de lo múltiple, como el de Nietzsche. Explorar y explotar al máximo ese desencuentro, sin intentar subsanarlo, permite construir la relación entre Nietzsche y América Latina en términos nietzscheanos, lo que implicaría deshacerse de la idea misma de América Latina en tanto sujeto, para concentrarse en la disección de sus fuerzas y en la potencia y miseria de sus pasiones.

Relativamente difundida na teoria democrática contemporânea, a dicotomia entre democracia epistêmica e democracia agonística é endossada por autores como Luis Felipe Miguel, Chantal Mouffe e Nadia Urbinati. De acordo com eles, a ideia de que a deliberação democrática possa funcionar como uma troca de argumentos racionais que visa à verdade é incompatível com o reconhecimento do conflito como um componente basilar da política. Tudo se passa, pois, como se a abordagem epistêmica estivesse fadada a obliterar a dimensão agonística (...) da política. A fim de problematizar semelhante entendimento, este artigo reconstrói a associação entre democracia e compromisso feita por John Stuart Mill, John Morley e Hans Kelsen e conclui que a conceitualização da democracia como compromisso oferece uma alternativa à dicotomia democracia epistêmica vs. democracia agonística.

RELAÇÃO E EFEITOS BIOQUÍMICO-NUTRICIONAIS SOBRE A METRITE EM VACAS -/- Emanuel Isaque Cordeiro da Silva Departamento de Agropecuária – IFPE Campus Belo Jardim [email protected] ou [email protected] WhatsApp: (82)98143-8399 -/- •__3. METRITE -/- O transtorno caracterizado pela inflamação do útero, devido a causas sépticas ou assépticas que atuam sobre ele, denomina-se genericamente como metrite. As metrites são afecções de grande importância, tanto pela frequência como pela gravidade. As metrites podem ser divididas segundo seu caráter anatômico, como mucosa (catarral), purulenta, hemorrágica, crupal, (...) pútrida e flegmonosa e segundo seu curso, em agudas e crônicas (FRAZER, 2005; GORDON, 1996). Estão associadas às doenças do puerpério. Quando a inflamação é limitada à mucosa é chamada de endometrite; e se ademais interessa a camada muscular denomina-se metrite ou miometrite; se afeta o revestimento peritoneal, perimetrite ou metroperitonite; e se a inflamação se estende ao paramétrio, ou seja, ao tecido conjuntivo pélvico e ligamentos, chama-se parametrite (FÖLDI, et al. 2006). A metrite ocorre em consequência de diversos acidentes que resultam de partos distócicos, após retenção fetal ou secundinas seguidas de putrefação, por arrancamento brutal dos cotilédones; por injeções uterinas irritantes; após o prolapso uterino; tudo o que favorece o desenvolvimento microbiano. Em fêmeas que se inseminam artificialmente sob condições sépticas ou de pobre destreza se produz endometrite seguida com infecundidade passageira, isto se produz como consequência das erosões produzidas pela pistola de inseminação, desassossego geral no procedimento ou por levar o sêmen a maior temperatura que a devida e em lugar inadequado. Algumas situações de origem nutricional se associam em maior ou menor grau com a incidência de metrite, em especial processos de retenção de placenta ou involução uterina de origem nutricional podem levar, de forma indireta, a incidência de metrite. 3.1 Relação energia e proteína Uma das situações de origem nutricional associada à metrite é o excesso de proteína crua na dieta. As vacas necessitam de um adequado fornecimento de proteína. No afã de suprir as necessidades nutricionais e evitar as limitações de aminoácidos, cai-se no erro de fornecer excessos de proteína, trazendo como consequência uma diminuição da eficiência reprodutiva, devido à relação dos altos níveis de proteína na dieta com a falha reprodutiva específica. Um excesso de proteína resulta num aumento da produção de amoníaco e, como consequência, numa maior síntese de ureia pelo fígado (BACH, 2000). Consequentemente, existe um aumento do nível de ureia no sangue, no útero e no muco vaginal. A nível uterino, a ureia parece ter um efeito sobre a função hormonal e depressora da proteção imunitária. O mecanismo específico baseia-se na toxicidade direta da ureia, na perda do balanço energético e na concentração de diaminas de ácido carbônico que favorecem a ampla difusão da ureia em todo o endométrio. O fornecimento de fontes alternativas de nitrogênio na alimentação dos animais vêm ganhando espaço no debate entre os especialista e a ureia é uma dessas fontes. Ela é conhecida como uma fonte de nitrogênio não-proteico (NNP), porém não se destaca tanto pelos inúmeros fatores negativos como a baixa aceitabilidade dos animais ou aos índices de intoxicação pela mesma. O rúmen necessita de um teor de 1% de nitrogênio para manter os mecanismos fisiológicos e a população microbiana, sendo assim, o produtor deve estar atento ao fornecimento desse mineral para seus animais. Especialistas apontam a fórmula de 30 g de ureia por dia para animais de 100 kg, e que essa quantidade nunca pode exceder os 200 g por animal por dia. Esses dados só podem ser postos em prática se as forrageiras existentes na propriedade não conseguirem suprir a exigência de 1% de nitrogênio no animal. Uma fonte vegetal de ótima qualidade e abundante em meios nutricionais e fonte extra de renda é a cana-de-açúcar. Ao nível hormonal a presença de ureia impede a manutenção do gradiente de pH (induzido pela progesterona) que existe entre as células apicais e basais da parede uterina (MARÍN & CÁRDENAS, 1999). Assim, a progesterona não consegue manter o gradiente de pH e aumenta a secreção de PGF2α, que afeta negativamente tanto a sobrevivência como o desenvolvimento embrionário. A nível imunológico, ocorre um efeito negativo devido à elevada concentração de amônio e ureia no sangue, o que diminui a atividade dos linfócitos e impede a defesa celular contra os agentes nocivos provocadores da metrite infecciosa, favorecendo o desenvolvimento microbiano. Para determinar a quantidade e a qualidade da nutrição proteica do animal são utilizados indicadores como a concentração de ureia no sangue e no leite. As proteínas, em geral, possuem inúmeras funções, dentre elas componentes estruturais, funções enzimáticas, funções hormonais, recepção de estímulos hormonais e armazenamento de informações genéticas. Na nutrição animal, as proteínas são divididas entre bruta (PB) e metabolizável (PM), ainda outras, mas o enfoque são essas. Os animais necessitam de níveis distintos de proteínas em suas respectivas fases de vida. Para elucidar melhor, tomemos como exemplo uma vaca nelore de 420 kg no final da gestação necessita, em média, de 389 g/dia de proteína metabolizável e, em média de 581 g/dia de proteína bruta. Os alimentos de origem vegetal (forrageiras) fornecem muito bem e eficazmente teores aceitáveis de proteínas, porém como o elemento mais presente é a fibra, faz-se necessário a suplementação nos animais, e um meio de suprir as necessidades dos mesmo, é optando por farelos de soja que possuem mais de 60% de proteína em sua composição, ou outras fontes alternativas como as farinhas de origem animal como a de sangue, por exemplo. A deficiência de fibra crua desencadeia principalmente uma deficiência de energia no ruminante; pois a partir da fibra formam-se os ácidos graxos voláteis (AGV) que constituem até 60% das fontes energéticas para estes animais. Devido à síntese reduzida de AGV, é muito baixa a concentração destes, são absorvidos pela corrente sanguínea e o animal entra em estado de déficit de precursores glicogênios. Como o consumo de alimento no pós-parto está reduzido, e não há a suficiente disposição de energia (deficiência de AGV principalmente ácido acético, devido a deficiência em fibra crua), o organismo realiza uma mobilização de ácidos graxos para a compensação energética. Os ácidos graxos são levados até acetil-CoA, este é convertido pelo fígado em corpos cetônicos que são utilizados em baixa concentração por alguns tecidos periféricos (cérebro) como fonte de energia, pois os excessos de corpos cetônicos produzem toxicidade. Os excessos de acetil-CoA no fígado podem sofrer condensação e converterem-se em β-hidroxi-β-metil-glutaril-CoA que serve como fonte de mevalonato (precursor do colesterol formado em excesso). Os excessos provocam fígado graxo que gera danos hepáticos, isso deprime a síntese de ácidos graxos para a formação do colesterol que se encontra diretamente implicado na síntese de estrogênios. Após o parto uma deficiência de estrogênio provoca de forma subsequente atonia uterina, retenção de placenta, endometrite puerperal e finalmente metrite. 3.2 Vitaminas Outra causa nutricional que incide na manifestação de metrite, é a vitamina A, que faz parte do grupo de vitaminas lipossolúveis e tem relevância especial na função reprodutiva. Esta exerce sua ação sobre a integridade estrutural e funcional das células epiteliais do organismo animal, atua sobre o crescimento, a reprodução e o desenvolvimento embrionário; mas seu papel principal é atuar como protetora dos epitélios, incluindo o endométrio. Além disso, tem um efeito estabilizador sobre várias membranas celulares e atua regulando a permeabilidade da membrana. A vitamina A, atua como estimuladora dos epitélios da mucosa tubária, uterina e vaginal, aumentando sua resistência contra os agentes infecciosos que produzem problemas que finalizam em metrite, também é necessária para as alterações histológicas que ocorrem na mucosa durante as diferentes fases do ciclo estral. Uma deficiência de vitamina A, pode causar morte embrionária, aborto, bezerros fracos ao nascimento e de forma subsequente uma retenção de placenta, (BACH, 2000) devido a não regulação da filtração de líquidos e gases através das membranas fetais; também dificulta a fecundação, devido à geração de uma atresia ovariana e à degeneração do epitélio germinal. Além disso, são produzidos edemas que ocasionam bezerros mortos ou prematuros (natimortos), o que provoca uma posterior retenção de placenta. Estas retenções provocam metaplasia queratinizam-te, dos epitélios da mucosa uterina-vaginal, o que provoca o aparecimento de metrite. Também, uma deficiência de outras vitaminas provocam o aparecimento de pequenas hemorragias, inchaço vulvar e degeneração epitelial das mucosas, em geral, isto provoca uma endometrite que posteriormente torna-se em metrite devido ao que se afeta a submucosa e a camada muscular do útero. Em relação ao pós-parto precoce, a capacidade de consumo de alimentos (forragem) é limitada, o que conduz, principalmente, a uma deficiência de fibras cruas na ruminação do animal, que conduzirá, em algumas circunstâncias, à predisposição para o desenvolvimento de metrite. Atentos a essas intempéries, o produtor deve estar atento aos requerimento exigidos pelos animais de vitaminas para que possam manter seu funcionamento normal e longe de quaisquer problema ou agente infeccioso ou patógeno. Para tanto, os níveis de vitaminas por categoria animal, deve prezar pelas quantidades conforme demonstrado nas tabelas abaixo: Tabela 1: Exigências de vitaminas por categoria animal em bovinos de corte -/- Categoria Vitamina A (UI/dia) Vitamina E (mg/dia) Vitamina D (UI/dia) Niacina (g/dia) Vacas lactantes 80.000 – 120.000 100 – 1.000 15.000 – 50.000 1 - 2 Vacas secas 75.000 – 125.000 500 – 900 10.000 – 20.000 0 – 1 Fonte: BERCHIELLI et al., 2006. Tabela 2: Exigências de vitaminas em vacas gestantes de corte -/- Vitamina UI/kg de MS A 2.800 D 275 Fonte: BERCHIELLI et al., 2006. Para que se consiga suprir todas essas quantidades requeridas dos animais, em especial, das vacas gestantes para que não venha a ocorrer a incidência de metrite ou outro transtorno reprodutivo, o criador poderá optar pela injeção direta de complexos vitamínicos e minerais mediante os inúmeros fármacos da indústria farmacêutica animal, ou poderá suprir essas necessidades fisiológicas mediante o fornecimento de rações com teores adequados de vitaminas, ou ainda por intermédio de alimentos volumosos que além das vitaminas necessárias fornecem também as fibras. As forrageiras, leguminosas e gramíneas fornecem minerais, fibras e vitaminas; dentre elas as espécies tifton (capim) apresenta cerca de 34,8% de vitamina A, o capim-tanzânia apresenta 24% e a alfafa 23,4%. Por fim, métodos para fornecimento de fibras, vitaminas e/ou minerais não faltam. Apoio -/- Realização •_ _referências bibliográficas -/- BACH, Alex; ESPAÑA, Purina.

Sport poses a number of important and no less significant questions, which, on the face of it, may not necessarily seem very important or significant to begin with – a peculiarity that we believe to be integral to sport itself. This article introduces, explores and outlines the psychoanalytic significance of this peculiarity. It explores how the emotions stirred by sport are intertwined with a realm of fiction and fantasy. Despite its lack of practical utility, sport carries an undeniable gravity, encapsulating (...) the aspirations of communities, nations and continents. As a result, psychoanalysis can be used to critically reflect on the purpose and meaning of sport: that is, why do we need sport, and why, for large sections of the world’s population, do we rely on it? Ultimately, while psychoanalysis maintains a unique relation to a variety of unexpected fields of study – including art, culture and neuroscience – we seek to add to this expanding list of inquiry by including sport in this critical domain. By utilising sport as a platform to elucidate psychoanalytic concepts, it is recognised that sport can also prompt questions for psychoanalysis. In so doing, theoretical discussions on the social, cultural and political dimensions of sport through psychoanalytic theory are introduced and applied. (shrink)

The reward system of science is the priority rule. The first scientist making a new discovery is rewarded with prestige, while second runners get little or nothing. Michael Strevens, following Philip Kitcher, defends this reward system, arguing that it incentivizes an efficient division of cognitive labor. I argue that this assessment depends on strong implicit assumptions about the replicability of findings. I question these assumptions on the basis of metascientific evidence and argue that the priority rule systematically discourages replication. My (...) analysis leads us to qualify Kitcher and Strevens’s contention that a priority-based reward system is normatively desirable for science. (shrink)

En este texto nos proponemos abordar la última clase del semanario de Deleuze sobre el poder en Foucault a partir de dos momentos. El primero tiene que ver con el concepto de imagen y la interpretación sobre el cine que ya venía siendo una constante —aunque marginalmente— en estas clases de Deleuze. Seguidamente, el segundo momento tiene que ver con la relación entre poder y resistencia que arroja como resultado una interpretación del pensamiento de Foucault por parte de Deleuze como (...) una obra viva y en constante construcción. Así, cumpliremos con la exigencia de una lectura que invita a pensar en los conceptos como herramientas de análisis integradas al desarrollo de situaciones donde el poder se presenta como noción central.

This collection highlights the new trend away from rationalism and toward empiricism in the epistemology of modality. Accordingly, the book represents a wide range of positions on the empirical sources of modal knowledge. Readers will find an introduction that surveys the field and provides a brief overview of the work, which progresses from empirically-sensitive rationalist accounts to fully empiricist accounts of modal knowledge. Early chapters focus on challenges to rationalist theories, essence-based approaches to modal knowledge, and the prospects for naturalizing (...) modal epistemology. The middle chapters present positive accounts that reject rationalism, but which stop short of advocating exclusive appeal to empirical sources of modal knowledge. The final chapters mark a transition toward exclusive reliance on empirical sources of modal knowledge. They explore ways of making similarity-based, analogical, inductive, and abductive arguments for modal claims based on empirical information. Modal epistemology is coming into its own as a field, and this book has the potential to anchor a new research agenda. (shrink)

The philosophy of perception has been mostly focused on vision, to the detriment of other modalities like audition or olfaction. In this paper I focus on olfaction and olfactory experience, and raise the following questions: is olfaction a perceptual-representational modality? If so, what does it represent? My goal in the paper is, firstly, to provide an affirmative answer to the first question, and secondly, to argue that olfaction represents odors in the form of olfactory objects, to which olfactory qualities are (...) attributed. In order to do this I develop an empirically adequate notion of olfactory object that is sensitive to the peculiarities of olfaction, and defend it against various objections. (shrink)

The intuitive distinction between natural and unnatural properties (e.g., green vs. grue) informs our theorizing not only in fundamental physics, but also in non-fundamental domains. This paper develops a reductive account of this broad notion of naturalness that covers non-fundamental properties: for a property to be natural, I propose, is for it to figure in a law of nature. After motivating the account, I defend it from a potential circularity charge. I argue that a suitably broad notion of lawhood can (...) be defined independently of naturalness, if we help ourselves to the notion of a fundamental physical property. I end by showing how the notions of naturalness and lawhood that my account delivers help illuminate a number of other important philosophical notions, like causation, reference/meaning, and rational induction.

This essay proposes a reductive account of robust macro-regularities. On the view proposed, regularities can earn their elite scientific status by featuring in good summaries of restricted regions in the space of physical possibilities: our “modal neighborhoods.” I argue that this view vindicates “nomic foundationalism”, while doing justice to the practice of invoking physically contingent generalizations in higher-level explanations. Moreover, the view suggests an explanation for the particular significance of robust macro-regularities: we rely on summaries of our modal neighborhoods when (...) reasoning hypothetically about “agentially accessible” possibilities.

One challenge faced by aesthetics is the development of an account able to trace out the continuities and discontinuities between general experience and aesthetic experiences. Regarding this issue, in this paper, I present an enactive model of some raw cognitive dynamics that might drive the progressive emergence of aesthetic experiences from the stream of general experience. The framework is based on specific aspects of John Dewey’s pragmatist philosophy and embodied aesthetic theories, while also taking into account research in ecological psychology, (...) cognitive sciences, and dynamic systems theory. The model focuses on dynamically relevant nodes at the pre-reflective and the reflective side of experience that would work as nested rhythmic constraints at different cognitive timescales with the potential to shunt experiences toward the aesthetic in everyday situations. My proposal constitutes a way to explore aesthetic experiences from an enactive perspective that regards them as transformative events in which cognitive processes entrain and are entrained by changes taking place in the environment, the brain, and the body.

In this paper I present reasons for us to accept the hypothesis that suspended judgment has correctness conditions, just like beliefs do. Roughly put, the idea is that suspended judgment about p is correct when both p and ¬p might be true in view of certain facts that characterize the subject’s situation. The reasons to accept that hypothesis are broadly theoretical ones: it adds unifying power to our epistemological theories, it delivers good and conservative consequences, and it allows us to (...) assess processes of reasoning involving attitudes of suspended judgment.

A key premise of the kalam cosmological argument is that the universe began to exist. However, while a number of philosophers have offered powerful criticisms of William Lane Craig’s defense of the premise, J.P. Moreland has also offered a number of unique arguments in support of it, and to date, little attention has been paid to these in the literature. In this paper, I attempt to go some way toward redressing this matter. In particular, I shall argue that Moreland’s philosophical (...) arguments against the possibility of traversing a beginningless past are unsuccessful. (shrink)

While most people believe the best possible life they could lead would be an immortal one, so‐called “immortality curmudgeons” disagree. Following Bernard Williams, they argue that, at best, we have no prudential reason to live an immortal life, and at worst, an immortal life would necessarily be bad for creatures like us. In this article, we examine Bernard Williams' seminal argument against the desirability of immortality and the subsequent literature it spawned. We first reconstruct and motivate Williams' somewhat cryptic argument (...) in three parts. After that, we elucidate and motivate the three best (and most influential) counterarguments to Williams' seminal argument. Finally, we review, and critically examine, two further distinct arguments in favor of the anti‐immortality position. (shrink)

El concepto de desarrollo humano del Programa de las Naciones Unidas para el Desarrollo (PNUD) surge en 1990 como una crítica a la consideración de la economía como el fin último de los esfuerzos del desarrollo. En la visión del PNUD, la economía es considerada un fin relativo, es decir, un fin y un medio para el desarrollo humano. Al considerar, por su parte, el fin del desarrollo humano, este es identificado con el ensanchamiento de las opciones y libertades de (...) que gozan los individuos. En este sentido, este concepto de desarrollo humano hace alusión a una práctica política más que a un entendimiento ético-ontológico del ser humano, evitando referirse a desarrollo humano entendido como un desarrollo del ser humano. Este artículo explora los antecedentes del concepto del desarrollo humano del PNUD y los fines que consideran estos enfoques previos. Se observa que la consideración subjetivista del PNUD proviene de la teoría de Amartya Sen, quien queda sujeto a la crítica objetivista de Martha Nussbaum al no considera un fin objetivo para los asuntos humanos, crítica que puede de igual manera aplicarse al concepto de desarrollo humano del PNUD.

The underlying contention guiding this collection is that psychoanalysis can provide a novel approach to theorising our investments in sport. When exploring, examining, discussing, and debating the fascination and frustrations that characterizes sport, what this collection will consider are the very ways in which we become “stuck” in sport. For us, getting “stuck” helpfully describes the degree to which one can both be interested in sport, following a particular team or training regularly, while also being frustrated, angered, and undermined by (...) sport (grievances, which, in most cases, in no way discount or prevent one’s very love of sport). What compounds this contradiction is that a psychoanalytic approach to sport does not necessarily provide or outline any answers to the problems of sport. Rather, we double-down on the fact there is no rational explanation as to why millions of people choose to partake in strenuous forms of physical exclusion for years on end, with the only reward being a medal or personal best for the lucky few—not to mention the multitudes who choose to watch these athletic spectacles. Certainly, this is not to say that sport does not have its explanations. We are all too familiar with the cliched responses and tired explanations: “it makes me feel good”, “it keeps me busy”, “it releases endorphins”, “I enjoy the social-side”, “my Dad followed this team, so, in a way, I’m continuing the tradition”. What goes amiss in such routine responses is why this specific activity—sport, in whatever form—is chosen? When so much of sport requires one to partake in choices that fundamentally affect one’s life, then we require a theoretical space in which we can begin to ask important questions of both sport and ourselves. On this basis, sport is not necessarily detached from our lives, a mere weekend past-time, separate from the world of work (although it can be described as such); instead, as this collection will assert, a psychoanalytic account of sport can allow us to question and explore what it is that makes us human and what is it about our inherent sociality that makes sport such an important part of so many lives. To do so, requires an investigation into the desires, fears, and fantasises that underscore the subject—the very phenomena that psychoanalysis seeks to examine. (shrink)

Foundational ontologies, central constructs in ontological investigations and engineering alike, are based on ontological categories. Firstly proposed by Aristotle as the very ur- elements from which the whole of reality can be derived, they are not easy to identify, let alone partition and/or hierarchize; in particular, the question of their number poses serious challenges. The late medieval philosopher Dietrich of Freiberg wrote around 1286 a tutorial that can help us today with this exceedingly difficult task. In this paper, I discuss (...) ontological categories and their importance for foundational ontologies from both the contemporary perspective and the original Aristotelian viewpoint, I provide the translation from the Latin into English of Dietrich's De origine II with an introductory elaboration, and I extract a foundational ontology–that is in fact a single-category one–from this text rooted in Dietrich's specification of types of subjecthood and his conception of intentionality as causal operation.

Ontologies are some of the most central constructs in today's large plethora of knowledge technologies, namely in the context of the semantic web. As their coinage indicates, they are direct heirs to the ontological investigations in the long Western philosophical tradition, but it is not easy to make bridges between them. Contemporary ontological commitments often take causality as a central aspect for the ur-segregation of entities, especially in scientific upper ontologies; theories of causality and philosophical ontological investigations often go hand-in-hand, (...) and were essentially inseparable in medieval thought. This constitutes the foundation for a bridge, and this article analyzes the causality-based ontology of the late medieval philosopher Dietrich of Freiberg from the viewpoint of today's upper-ontology engineering. In this bridging attempt, it offers a translation into English of the first part of Dietrich's De origine (abbreviated title) that is a compromise between traditional scholarly translations of medieval Latin philosophical texts and contemporary ontology.

Recent years have seen a heightened focus on the study of minimal forms of awareness during sleep to advance the study of consciousness and understand what makes a state conscious. This focus draws on an increased interest in anecdotical descriptions made by classic Indian philosophical traditions about unusual forms of awareness during sleep. For instance, in the so-called state of witnessing-sleep or luminosity sleep, one is said to reach a state that goes beyond ordinary dreaming and abide in a state (...) of just awareness, a state in which one is not aware of anything else other than one’s own awareness. Moreover, for these traditions, this state is taken to be the essence or background of consciousness. Reports on such a state opens the door to exciting new lines of research in the study of consciousness, such as inquiry into the so-called “objectless” awareness during sleep—states of awareness that lack an ordinary object of awareness. In this two-staged research project, we attempted to find the phenomenological blueprints of such forms of awareness during sleep in 18 participants by conducting phenomenological interviews, informed by a novel tool in qualitative research, the micro-phenomenological interview (MPI) method. Following a phenomenological analysis, we isolated a similar phase across 12 reported experiences labelled as ‘nothingness phase’ since it described what participants took to be an experience of ‘nothingness’. his common phase was characterised by minimal sense of self—a bodiless self, yet experienced as being ‘somewhere’—, the presence of non-modal sensations, relatively pleasant emotions, an absence of visual experience, wide and unfocused attention, and an awareness of the state as it unfolded.

Why should we avoid incoherence? An influential view tells us that incoherent combinations of attitudes are such that it is impossible for all of those attitudes to be simultaneously vindicated by the evidence. But it is not clear whether this view successfully explains what is wrong with certain akratic doxastic states. In this paper I flesh out an alternative response to that question, one according to which the problem with incoherent combinations of attitudes is that it is impossible for all (...) of those attitudes to be simultaneously knowledgeable. This alternative response explains what is wrong with akratic combinations of attitudes using commonly accepted epistemological theses. The paper still shows how this proposal is able to explain the badness of incoherent combinations involving the absence of attitudes, suspended judgment and credence. These explanations deploy the notions of knowledge and being in a position to know, instead of the notion of responding properly to the evidence. Finally, I suggest that this picture can be generalized to the realm of practical rationality as well. (shrink)

Con el método de las letras numeradas se podrá construir un robot con inteligencia artificial que pueda tener infinitos conocimientos. Pero no podrá tener libre albedrío, ya que éste solo se puede tener si se posee vida. Como las máquinas con inteligencia artificial no pueden poseer vida nunca podrán por su propia cuenta ser un peligro para la humanidad, solo podrán actuar según lo programado por los programadores. La vida nos obliga a vivir, a tener necesidades vivientes que nos hacen (...) poder actuar por nuestra propia cuenta, por eso tenemos libre albedrío. Gracias a que necesitamos vivir, tanto para lo bueno como para lo malo, podemos amar, odiar, desear, ambicionar, etc., y por eso podemos poseer libre albedrío. El lenguaje de las letras numeradas será el medio que se utilizará para que las máquinas puedan pensar y adquirir información sin fin, informaciones que la podrán adquirir por medio de los sentidos artificiales y de los programas que se les instalen. Las informaciones que obtenemos con nuestros sentidos se obtienen de manera cuántica binaria, aunque cada sentido tenga su propio lenguaje. Estas informaciones cuánticas binarias se llevarán al pensamiento a velocidades cuánticas, el cual se encargará de buscar los significados de las informaciones, como si buscara en un diccionario cuántico, para así poder saber en forma de números binarios qué significa cada información obtenida. Eso es pensar. (shrink)

For millennia, knowledge has eluded a precise definition. The industrialization of knowledge (IoK) and the associated proliferation of the so-called knowledge communities in the last few decades caused this state of affairs to deteriorate, namely by creating a trio composed of data, knowledge, and information (DIK) that is not unlike the aporia of the trinity in philosophy. This calls for a general theory of knowledge (ToK) that can work as a foundation for a science of knowledge (SoK) and additionally distinguishes (...) knowledge from both data and information. In this paper, I attempt to sketch this generality via the establishing of both knowledge structures and knowledge systems that can then be adopted/adapted by the diverse communities for the respective knowledge technologies and practices. This is achieved by means of a formal–indeed, mathematical–approach to epistemological matters a.k.a. formal epistemology. The corresponding application focus is on knowledge systems implementable as computer programs. (shrink)

The logos question, one of the most important among the subjects that traverse the Plato's Sophist, has in fact some different aspects: the criticism of father Parmenides' logos, that is unable to speak about the not-being, but also about the being; the relations between logos and its cognates, phantasia, doxa and dianoia; the logos’ complex structure, that is a compound with onoma and rema; the difference between naming and saying, two distinct but inseparable actions; the logical and ontological conditions that (...) make possible to say the truth, or to lie or simply to joke; the necessity of a most flexible logos that allows us to speak about the not-being, and about the being, but at the same time is a logos dangerously similar to the sophist’ one; finally, the identity between the power to produce “spoken images” and the very power to speak. The aim of the present article is giving a systematical view of the matter that grasps all these faces. (shrink)
