RELAÇÃO E EFEITOS BIOQUÍMICO-NUTRICIONAIS SOBRE O RETARDO DA MATURIDADE SEXUAL EM BOVINOS -/- -/- Emanuel Isaque Cordeiro da Silva -/- Departamento de Agropecuária – IFPE Campus Belo Jardim -/- [email protected] ou [email protected] -/- WhatsApp: (82)98143-8399 -/- -/- 12. RETARDO DA MATURIDADE SEXUAL -/- -/- Nos animais em crescimento, as deficiências em qualquer dos nutrientes: proteína, energia, macro ou microminerais, vitaminas e aporte hídrico, geram inibição das sínteses de proteínas específicas como os fatores de crescimento. Neste tipo de situação, as taxas (...) de ganho de peso e o desenvolvimento dos diferentes segmentos do trato reprodutivo se alteram. Os animais atrasam a idade a que chegam à puberdade, atrasando a entrada na vida produtiva como animais aptos a se reproduzir. O quadro de atraso à puberdade ocasiona atraso na idade a que se apresenta o primeiro parto, fator responsável por grande parte das falhas na eficiência reprodutiva. Sem dúvida, aspectos nutricionais são os maiores limitantes no crescimento e na maturidade reprodutiva, sendo assim, esse trabalho têm como cunho a apresentação de alguns destes fatores: -/- 12.1 Relação Energia:Proteína -/- A maturidade sexual relaciona-se com um consumo adequado de energia e com a obtenção de um peso corporal adequado; o crescimento depende, em grande medida, da ingestão abundante de elementos energéticos. Uma ração deficiente em energia diminui a velocidade de crescimento, reduz a produção de leite, retarda a puberdade, reduz a fertilidade e diminui a resistência às doenças e ao parasitismo. -/- Uma das causas mais comuns da baixa fertilidade e do atraso da maturidade sexual nas vacas leiteiras é a falta de energia em relação às necessidades do animal ou um balanço de energia negativo; além disso, este atraso no início tardio da maturidade sexual diminui o tempo de vida durante o qual os animais têm uma reprodução ativa. -/- A falta de energia na ração pode ser causada por um consumo insuficiente de alimentos ou por uma baixa digestibilidade de seus componentes (dieta de baixa qualidade) e, por um teor elevado de umidade na dieta. O baixo consumo de energia é normalmente o resultado de restrições alimentares. Em qualquer uma das situações, a falta de energia impede o animal de expressar seu potencial genético de produção e o problema complica-se se, por sua vez, existe deficiência em proteínas, minerais e vitaminas. -/- Como referenciado anteriormente, a energia têm papel fundamental em todos os mecanismos fisiológicos do animal, seja para a reprodução, fornecimento de leite ou para produção de carne, uma vez que possui relação direta com as mitocôndrias celulares. A energia é considerada um tipo de gordura, e possui relação direta com o sistema reprodutivo da vaca. Para a produção de leite, uma vaca pode utilizar suas reservas de gordura e transformá-las em leite, isto é, a cada quilo de gordura corporal pode-se obter de 7 a 9 quilos de leite. O fornecimento de energia têm como fator a categoria animal, o sistema produtivo, a idade etc. logo, a administração de energia deve obedecer os parâmetros de 1,75 a 1,25 Mcal/kg do alimento fornecido, seja matéria seca, volumoso ou ração concentrada. Vale frisar novamente que os níveis de energia administrada devem ser altos (1,72 Mcal/kg) para as vacas no início da lactação e deve-se diminuir gradativamente conforme chega o final da lactação, chegando a 1,54 Mcal/kg ou menos. No caso de prevenção contra o retardamento dos animais à idade reprodutiva, os níveis de energia para as bezerras de 0-3 meses com ± 150 kg deve ser de 1,70 Mcal/kg de MS para mantença e de 1,06 Mcal para ganho de peso diário; para bezerras com idade entre 6-12 meses e um peso de ± 250 kg o nível de energia deve ser de 1,54 Mcal para mantença e de 0,97 para ganho; por fim, para bezerras chegando a categoria de novilhas (> 12 meses) o ideal é o fornecimento de 1,39 Mcal para mantença e de 0,81 Mcal para ganho. Os alimentos que mais fornecem energia são o sebo, a gordura protegida, o milho, etc. -/- O efeito da proteína da dieta na reprodução é complexo. Em geral, quantidades inadequadas de proteína na dieta reduzem a produção de leite e o desempenho reprodutivo (maturidade sexual). Deficiências de proteínas diminuem os níveis de proteínas de reserva ou de transporte no sangue, fígado e músculos o que predispõe o animal a várias doenças que podem levar a não manifestação da maturidade sexual ou mesmo a morte. -/- Há tipos de proteínas como a PB (proteína bruta), a PDR (proteína degradada no rúmen), proteína metabolizável entre outras, ambas possuem relação com a PB e são primordiais no entendimento da nutrição de ruminantes. Os níveis de PDR se forem baixos mostra uma boa população microbiana presente no rúmen do animal, esse compartimento que se desenvolve conforme a ingestão de alimentos concentrados. -/- Para que se possa prevenir o retardamento dos animais à maturidade sexual, deve-se estar atentos aos níveis de proteína que se administra aos animais, em especial para as bezerras que entrarão logo na puberdade estando aptas para se reproduzir. Contudo, o tipo e a quantidade de proteína se limita a fatores como os ingredientes da ração, método alimentar utilizado na propriedade e o potencial produtivo do lote que se maneja. Sendo assim, os níveis oscilam conforme a categoria, idade e peso como demonstra na tabela 1, que traz os níveis ideias de proteína que devem estar presentes na alimentação das bezerras conforme idade e peso médio das mesmas. -/- Tabela 1: Exigências de proteína em bezerras e novilha -/- Nutriente 3-6 meses (± 150 kg) 6-12 meses (± 250 kg) > 12 meses (± 400 kg) -/- PB % 16 12 12 -/- PDR % 8,2 4,3 2,1 -/- Fonte: TEIXEIRA, 1997. -/- Para que as bezerras entrem na maturidade sexual sem atraso ou quaisquer problema, é ideal que a ração que viera ser fornecida para as mesmas possuam uma quantidade básica de 22% de PB presente na composição. Os alimentos mais proteicos são os de origem animal como a farinha de sangue, de penas etc., porém sua administração deve ser limitada. Sendo assim, a tabela 2 traz os possíveis melhores alimentos a serem ofertados aos animais e sua quantidade diária para que se possa suprir os requerimentos dos animais e prevenir o retardamento sexual ou qualquer outro problema reprodutivo que tenha relação nutricional. -/- Tabela 2: Alimentos proteicos e quantidades ideais para bovinos -/- Alimento PB% Quantidade % da mistura ou kg/cab./dia -/- Caroço de algodão 21 ± 50% da mistura da ração (1 kg = 0,5 kg de caroço) -/- Farelo de glúten de milho 23 Pode substituir o volumoso (máximo 3,5 kg/cab./dia) -/- Grão de soja 38 ± 20% da mistura (1 kg = 0,2 kg de grão) ou no máximo 2,5-3,5 kg/cab./dia -/- Farelo de algodão 41 ± 30-40% da mistura (1 kg = 0,3-0,4 kg de farelo) ou no máximo 4,5 kg/cab./dia -/- Fonte: TEIXEIRA, 1997. -/- A Ureia e outras substâncias que contêm nitrogênio não proteico (NNP) podem ser utilizadas pelos microrganismos do rúmen para a produção de proteínas bacterinas. Em geral, a utilização da NNP não é recomendada, exceto em situações especiais de alimentação e sob controle técnico, uma vez que um manejo inadequado, nomeadamente de excessos de consumo, pode provocar intoxicações com efeitos letais (ROIG, 2003; FERGUSON et al., 1989). É claro que as fontes de NNP não possuem aminoácidos e que muitos deles são essenciais e não são sintetizados pela microbiota ruminal. -/- Alguns autores argumentam que o nitrogênio não proteico (NNP) como a ureia, pode ser muito bem utilizado desde que não exceda um terço do total de nitrogênio na dieta diária ou 3% da ração de grãos de cereais e após adaptação gradual de, pelo menos, três semanas. A boa utilização da ureia nos ruminantes depende da ração conter pelo menos 75% de nutrientes digestíveis totais NDT, disponibilidade suficiente de amido e de CNE para converter o nitrogênio da ureia em proteína microbiana e quando o teor de proteína verdadeira da ração não for inferior a 12% (ROIG, 2003). -/- 12.2 Minerais (K e I) -/- Um excesso de potássio no sangue ocorre quando o consumo excede a capacidade do rim de o eliminar, provocando um atraso na maturidade sexual, ciclos sexuais irregulares e baixa natalidade; também interfere na absorção intestinal do magnésio, dificultando a absorção e o metabolismo do cálcio, magnésio e sódio; geralmente afeta fêmeas de alta produção leiteira (com o leite é excretado muito magnésio). -/- No macho, o excesso de potássio diminui a fecundidade, altera as vesículas seminais e influencia a composição espermática. Na fêmea prejudicaria os ciclos sexuais (duração e intensidade). -/- A excreção de íons de potássio diminui quando se ingere pouca quantidade deste elemento e de sódio, e quando há acidose aguda ou insuficiência das glândulas adrenais. -/- O potássio é um elemento de muitas funções no metabolismo animal e participa de múltiplos mecanismos fisiológicos, dentre eles o reprodutivo. Sendo assim, é importante o criador estar atento sobre a administração do mineral na alimentação das bezerras que vão entrar para a maturidade sexual. De forma geral, é indicado fornecer matéria seca que contenha K na ordem de 0,6 a 1% da composição do alimento. Em média, uma vaca de 600 kg que produz 15 kg de leite ingira cerca de 230 gramas desse mineral diariamente. -/- Em crescimento, a função tireoide tem um papel protetor da sexualidade e estimula a puberdade por suas relações com as funções hipofisária e ovariana, atuando como sensibilizador da gônada para o aparecimento do estro; sendo, na fêmea sinérgico com a FSH. Uma deficiência na produção de hormonas da tireoide induzirá uma redução na troca de energia e na liberação de calor corporal, ou seja, ocorre uma diminuição no metabolismo basal do -/- As iodo-proteínas ou tireoproteínas (T3 e T4) beneficiam o crescimento e a secreção láctea, no macho estimulam a puberdade (maturidade sexual) e são gametogênicas (a hipófise é estimulada pela tiroxina e a vitamina A). -/- Para se livrar do atraso e da desordem da administração dos animais e do cronograma da fazenda, o proprietário deve atentar ao fornecimento adequado de I que varia entre 0,34 e 0,88 mg/kg de MS. -/- As formas de prevenção por parte desses minerais poderá ser manejada através dos alimentos, da água ou via suplementação mineral injetável. Por fim, o criador poderá ficar tranquilo e ter seu cronograma estabelecido sendo posto e prática e obtendo êxito no plantel. -/- -/- REFERÊNCIAS BIBLIOGRÁFICAS -/- -/- BARRENHO, Gonçalo José Pinheiro.

It is not uncommon for philosophers to name disinterestedness, or some like feature, as an essential characteristic of love. Such theorists claim that in genuine love, one’s concern for her beloved must be non-instrumental, non-egocentric, or even selfless. These views prompt the question, “What, if any, positive role might self-interestedness play in genuine love?” In this paper, I argue that attachment, an attitude marked primarily by self-focused emotions and emotional predispositions, helps constitute the meaning and import of at least some (...) kinds of adult reciprocal love. In this way, attachment represents a type of self-interestedness that not only contributes positively to such relationships but is also essential to them. (shrink)

This book, now open-access from OUP, develops a normative theory of political responsibility for solidarity with poor populations by engaging closely with empirical studies of poor-led social movements in the Global South. Monique Deveaux rejects familiar ethical framings of problems of poverty and inequality by arguing that normative thinking about antipoverty remedies needs to engage closely with the aims, insights, and actions of “pro-poor,” poor-led social movements. Defending the idea of a political responsibility for solidarity, nonpoor outsiders—individuals, institutions, and (...) states—can help to advance a transformative anti-poverty agenda only by supporting the efforts of these movements.

We often use the term “attachment” to describe our emotional connectedness to objects in the world. We become attached to our careers, to our homes, to certain ideas, and perhaps most importantly, to other people. Interestingly, despite its import and ubiquity in our everyday lives, the topic of attachment per se has been largely ignored in the philosophy literature. I address this lacuna by identifying attachment as a rich “mode of mattering” that can help to inform certain aspects of agency (...) and emotion. First, drawing on insights from Ancient stoicism and developmental and clinical psychology, I suggest that the relevant form of attachment involves a felt need for its object and a particular relationship between the object and the attached agent’s sense of security. I then argue that these features serve to distinguish the attitude from the more philosophically familiar notion of caring. Finally, I show that recognizing this form of attachment as a distinct mode of mattering has important implications for understanding grief. (shrink)

This paper investigates the semantics of implicit comparatives (Alice is tall compared to Bob) and its connections to the semantics of explicit comparatives (Alice is taller than Bob) and sentences with adjectives in plain positive form (Alice is tall). We consider evidence from two experiments that tested judgments about these three kinds of sentence, and provide a semantics for implicit comparatives from the perspective of degree semantics.

The Lewis-Sider argument from vagueness is one of the most powerful objections against restricted composition. Many have resisted the argument by rejecting its key premise, namely that existence is not vague. In this paper, I argue that this strategy is ineffective as a response to vagueness-based objections against restricted composition. To that end, I formulate a new argument against restricted composition: the argument from determinate vagueness. Unlike the Lewis-Sider argument, my argument doesn’t require accepting that existence is not vague, but (...) only that it is not vague in a specific way, which, I argue, is entailed by restricted composition. I show that the rejection of this species of vague existence follows from assumptions even friends of vague existence should be happy to accept. (shrink)

Due to the COVID-19 Pandemic, several changes have been forcibly made and observed in various fields and areas of society, one of which include the field of education; the foundation of the formation of intellect and knowledge. After two years of studying indoors and private educational institutions holding virtual classes, the time has finally come for students to be re- adjusted once more to the blended mode of learning; a combination of virtual and in-person classes. Thus, this study aimed to (...) investigate the development of students’ study habits and how these habits could potentially affect the students’ academic achievement or performance. The study utilized a descriptivecorrelational design to examine the impact of study habits to the academic performance of 137 senior high school students. The study made use of the Palsane and Sharma’s Study Habits Inventory, or also known as PSSHI, and using this instrument, the study has been able to procure sufficient results that will answer the present study’s problems. Using linear regression analysis, the present study found that there was a significance between the study habits and academic performance of the senior high school students, thus the study’s null hypothesis was eventually rejected.

Psychologists often characterize the infant’s attachment to her primary caregiver as love. Philosophical accounts of love, however, tend to speak against this possibility. Love is typically thought to require sophisticated cognitive capacities that infants do not possess. Nevertheless, there are important similarities between the infant-primary caregiver bond and mature love, and the former is commonly thought to play an important role in one’s capacity for the latter. In this work, I examine the relationship between the infant-primary caregiver bond and love. (...) I argue that while these very early attachments do not represent genuine love, a fuller understanding of them can inform extant philosophical views of love. (shrink)

This article reflects on whether today, there is a need for a ‘new’ educational ideal of rationality. To articulate that objective, a critical analysis is made of the pedagogical ideas underlying two conflicting trends: transhumanism and critical thinking. First, the distinctive identity of the transhumanist philosophical movement is examined in terms of its partial ascription to, and, given its attempts to overcome it, its renunciation of Humanism. In the face of the apparent promises and pitfalls that techno-science portends for pedagogical (...) discourse, a distrust of reason is imminent. Contrary to such an assumption, critical thinking, as the embodiment of rationality in Israel Scheffler’s conception, illuminates the inconsistencies of scientific imperialism that conceal the moral-rational aspects of teaching. In view of the above, the discussion focuses on the relationship between theory and practice, justification and commitment, fallibility and wisdom; in short, between the moral and the rational of any educational ideal to be proposed.___________________________________________________________________________________________ ____________________________________________________________________________________________________ ________________________________ -/- Questo articolo riflette sulla necessità di un “nuovo” ideale educativo di razionalità. Per articolare tale obiettivo, viene effettuata un’analisi critica delle idee pedagogiche alla base di due tendenze in conflitto: il transumanesimo e il pensiero critico. In primo luogo, si esamina l’identità distintiva del movimento filosofico transumanista in termini di parziale ascrizione e, visti i suoi tentativi di superamento, di rinuncia all’Umanesimo. Di fronte alle apparenti promesse e insidie che la tecno-scienza comporta per il discorso pedagogico, si profila una sfiducia nella ragione. Contrariamente a tale ipotesi, il pensiero critico, in quanto incarnazione della razionalità nella concezione di Israel Scheffler, illumina le incongruenze dell’imperialismo scientifico che nascondono gli aspetti morali-razionali dell’insegnamento. Alla luce di quanto detto, la discussione si concentra sul rapporto tra teoria e pratica, giustificazione e impegno, fallibilità e saggezza; in breve, tra morale e razionale di qualsiasi ideale educativo da proporre.___________________________________________________________________________________________ ____________________________________________________________________________________________________ ________________________________________________________________HOW TO CITE / CÓMO CITAR: Castillo, P.

How should liberal democratic states respond to cultural practices and arrangements that run afoul of liberal norms and laws? This article argues for a reframing of the challenges posed by traditional or nonliberal cultural minorities. The author suggests that viewed from up close, such dilemmas are revealed to be primarily intracultural rather than intercultural conflicts, and reflect the political and practical interests of factions of communities much more than deep moral differences. Using the example of the reform of customary marriage (...) laws in post-apartheid South Africa, this article makes the case for a more pragmatic, politically focused approach to resolving conflicts of culture that it is argued is both more democratic and effective than alternatives recently advanced by liberals and deliberative democracy theorists.

Philosophers have urged that considerations about the psychopath’s capacity for practical rationality can help to advance metaethical debates. These debates include the role of rational faculties in moral judgment and action, the relationship between moral judgment and moral motivation, and the capacities required for morally responsible agency. I discuss how the psychopath’s capacity for practical reason features in these debates, and I identify several takeaway lessons from the relevant literature. Specifically, I show how the insights contained therein can illuminate the (...) complex structure of practical rationality, inform our standards for an adequate theory of practical reason, and frame our thinking about the significance of rational capacities in moral theory and social practice.

Addiction and certain varieties of interpersonal attachment share strikingly similar psycho-behavioral structures. Neuroscientists, psychologists, and philosophers have often adduced such similarities between addiction and attachment to argue that many typical cases of romantic love represent addictions to one’s partner and thus might be appropriate candidates for medical treatment. In this paper, I argue for the relatively neglected thesis that some paradigmatic cases of addiction are aptly characterized as emotional attachments to their objects. This has implications for how we should understand (...) the nature of addiction and for the ethics of attachment more broadly. (shrink)

The idea that we need our beloveds has a rich and longstanding history in classic literature, pop culture, social sciences, and of course, philosophical treatments of love. Yet on little reflection, the idea that one needs one’s beloved is as puzzling as it is familiar. In what, if any sense, do we really need our beloveds? And insofar as we do need them, is this feature of love something to be celebrated or lamented? In the relevant philosophical literature, there are (...) various ways of understanding the type(s) of psychological need internal to love and whether and how the necessity in question contributes to love’s value. In this chapter, I survey and critically analyze several accounts of felt necessity in love and advocate for a philosophically neglected perspective on the nature and value of needing our beloveds.

Dietmar Hübner and Lucie White question the ethical justification of employing risky neurosurgical interventions to treat imprisoned psychopaths. They argue that (1) such interventions would confer no medical benefit on the psychopath as there is no “subjective suffering” involved in psychopathy and (2) psychopaths could not voluntarily consent to such procedures because they could have no “internal motivation” for doing so. In the course of their discussion, the authors insightfully show that certain aspects of the psychopath’s personality structure are especially (...) relevant to assessing the ethics of risky treatment options. As I argue, however, the particular conclusions that the authors draw are too strong. A deeper look at the psychopathic profile casts doubt on (1) and (2). In some cases, psychopaths can be plausibly construed as experiencing subjective suffering on account of their disorder and as appropriately motivated to voluntarily consent to neurosurgical treatment. After arguing for this view, I suggest that the psychopath’s consent to neurosurgical intervention might nonetheless be problematic, as their emotional incapacities might preclude their abilities to adequately appreciate the relevant risks.

One of the significant problems for philosophy’s development into a more diverse discipline is the familiar sharp reduction in the proportion of women and students of color after initial, introductory-level courses. This contributes to a lack in the breadth of perspective and experience that both upper-level students and faculty bring to philosophy, which in turn undermines the strength of the discipline as a whole. Much of the transformation of philosophy must necessarily happen at the departmental, and even university, level; but (...) there are, nonetheless, a number of strategies available to individual teachers of philosophy to help to retain marginalized students—from the composition of course syllabi and assignment choices, to increased awareness of challenges within the discipline to students’ success and embracing error as a learning tool. This variety of pedagogical tools provides a means to help to make philosophy more broadly inclusive. (shrink)

Linguistics of Saying is to be analyzed in the speech act conceived as an act of knowing. The speaking, saying and knowing subject, based on contexts and the principles of congruency and trust in the speech of other speakers, will create meanings and interpret the sense of utterances supplying the deficiencies of language by means of the intellective operations mentally executed in the act of speech. In the intellective operations you can see three steps or processes: first the starting point, (...) intuition or aísthesis; second, the process of abstraction; and third, the inverse: the process of determination or fixing the construct created. (shrink)

Linguistics of saying studies language in its birth. Language is the mental activity executed by speaking subjects. Linguistics of saying consists in analyzing speech acts as the result of an act of knowing. Speaking subjects speak because they have something to say. Tthey say because they define themselves before the circumstance they are in. And this is possible because they are able to know. Speaking, then, is speaking, saying and knowing. In this sense there is a progressive determination. Knowing makes (...) possible saying, and saying determines speaking, or, in other words: speaking involves saying and knowing, and saying involves knowing. The problem thus is to determine the meaningful intentional purpose of the individual speaker to say something in every speech act. (shrink)

Language is nothing but human subjects in as much as they speak, say and know. Language is something coming from the inside of the speaking subject manifest in the intentional meaningful purpose of the individual speaker. A language, on the contrary, is something coming from the outside, from the speech community, something offered to the speaking subject from the tradition in the technique of speaking. The speech act is the performance of an intuition by the subject, both individual and social.

In both scientific and popular circles it is often said that we are in the midst of a sixth mass extinction. Although the urgency of our present environmental crises is not in doubt, such claims of a present mass extinction are highly controversial scientifically. Our aims are, first, to get to the bottom of this scientific debate by shedding philosophical light on the many conceptual and methodological challenges involved in answering this scientific question, and, second, to offer new philosophical perspectives (...) on what the value of asking this question has been — and whether that value persists today. We show that the conceptual challenges in defining ‘mass extinction’, uncertainties in past and present diversity assessments, and data incommensurabilities undermine a straightforward answer to the question of whether we are in, or entering, a sixth mass extinction today. More broadly we argue that an excessive focus on the mass extinction framing can be misleading for present conservation efforts and may lead us to miss out on the many other valuable insights that Earth’s deep time can offer in guiding our future.

Human beings make themselves with language in history. Language defines human beings making them subjects of their being and mode of being. In this sense language is essential and exclusive of humans. The problem with language consists in explaining the reality of language, something internal to speakers but manifesting itself as external to them.

The human subject in as much as he knows transforms the sensitive and concrete (the thing perceived) into abstract (an image of the thing perceived), the abstract into an idea (imaginative representation of the thing abstracted), and ideas into contents of conscience (meanings). The last step in the creation of meanings, something being executed in the speech act, consists in fixing the construct mentally created thus making it objectified meanings in the conscience of speakers. The interchange amongst the different steps (...) in the creation of meaning manifests lógos, the state lived by speakers in their interior when speaking, created and developed in words and because of words. (shrink)

Meaning defines language because it is the internal function of language. At the same time, meaning does not exist unless in language and because of language. From the point of view of the speaking subject meaning is contents of conscience. From the point of view of a language, meaning is the objectification of knowledge in linguistic signs. And from the point of view of the individual speaking subject, meaning is the expressive intentional purpose to say something.

En este artículo se plantea una reconsideración de la elección del reduccionismo de Parfit en Razones y personas como la posición que mejor explica el vínculo de dos sucesos mentales separados en el tiempo. Sin embargo, veremos cómo Parfit basa dicha elección en la consideración de la noción de persona como una sustancia, lo que en principio deja fuera cualquier otra perspectiva. El problema aparece cuando éste no considera apropiadamente el origen histórico de la pregunta en Locke, donde la noción (...) de “persona” se caracteriza en función de la “conciencia de sí”, lo que abre la posibilidad de entender dicha noción a partir de su naturaleza modal en vez de sustancial. En esta medida, se verá cómo esta tercera alternativa incluye una explicación de la conciencia de sí que podría considerarse más razonable bajo los propios términos de Parfit. (shrink)

El acto lingüístico como acto de hablar, decir y conocer es una actividad que realiza el sujeto desde lo profundo de su conciencia. Consiste en la síntesis cognoscitiva que realiza el hablante de su intuición y de lo que añade mediante su imaginación y su razón, convirtiéndola en palabras de una lengua. El acto lingüístico y, por tanto, el lenguaje, es la proyección hacia las cosas de lo que el sujeto realiza en su interior. Las cosas así tienen un grado (...) de realidad relativo, el que el sujeto les da proyectando su intención significativa hacia lo que le rodea, utilizando para ello las palabras de una lengua, creando así su verdad o su logos. Mi intención en este artículo es reflexionar sobre la realidad humana del acto lingüístico en cuanto que es la respuesta del sujeto que vive una situación dada. (shrink)

En Die Sache selbst (PhG, pp. 333 ss.), Hegel expone la pretensión de un individuo racional según la cual puede expresar su propia “naturaleza en el obrar” (Siep, 2015, p. 161). Esta es entendida por el individuo en función de su fidelidad a un estado mental interno al agente; esta posición ha sido llamada “compatibilismo” (Pippin, 2008, p. 148). No obstante, Hegel sostiene que la causa de dicha acción no puede ser realmente fiel a su naturaleza a menos que el (...) individuo sea consciente de su contexto social. (shrink)

Este artículo se propone la tarea de evaluar al utilitarismo de regla en distintos aspectos, a saber, en tanto es capaz de dar solución a casos difíciles sin consecuencias indeseables y si, en caso de ser resueltas, podrían considerarse como una solución distinta al utilitarismo de acto. De esta forma, responder la segunda pregunta va a permitir evaluar la primera, en la medida en que parece que el utilitarismo de regla no puede distanciarse apropiadamente del utilitarismo de acto debido a (...) dos razones, en primer lugar, porque, desde cierta perspectiva, el utilitarismo de regla es extensionalmente idéntico al de acto y no ofrece una alternativa, o bien, ofrece una alternativa no utilitarista.

Este artículo se propone analizar las razones por las cuales Hegel afirma en la Fenomenología del Espíritu que el modelo de autoconciencia Yo=Yo no es propiamente autoconciencia. Lamentablemente, se verá que la evidencia de la Fenomenología resulta insuficiente para esta tarea; por lo que, se complementará con un análisis de ciertos pasajes del escrito sobre la Diferencia entre los sistemas de filosofía de Fichte y Schelling en la medida en que allí se encuentra una versión más detallada de los fundamentos (...) de la crítica a dicho modelo. La evidencia conjunta pretende justificar que el modelo cuyo principio absoluto es Yo=Yo necesariamente es incapaz de constituir autoconciencia en el contexto de la Fenomenología. Asimismo, se podría llegar a una tesis más fuerte, puesto que se verá que estos elementos que se proponen como necesarios cumplen la función de dato insoslayable que cualquier modelo de autoconciencia debe asumir si efectivamente busca explicar la relación de la conciencia consigo misma.

El presente artículo se propone la tarea de interpretar la noción de infinito (τὸ ἄπειρον), expuesta por Aristóteles en su Física (1995), a la luz de la noción de trascendental, tal como la presenta en la Crítica de la razón pura (2011). Esta propuesta surge a partir del estatuto único que Aristóteles le otorga a la noción de infinito potencial, el que no es ni sustancia ni accidente. Esto sugiere una interpretación no objetual del mismo, que lo aproxima a la (...) noción de trascendental propuesta por Kant (cf. KrV, B25). Esta exposición puede ser orientadora en la medida en que Kant y sus comentaristas tienen mejores herramientas conceptuales para abordar el extraño concepto de infinito potencial aristotélico.

El presente artículo se encarga de ampliar la afirmación kantiana según la cual la unidad analítica presupone la unidad sintética (Kant, KrV, B 133) a una discusión en torno a la conciencia de dicha unidad sintética. Sostendré que muchas posiciones han incomprendido la naturaleza de esta forma de conciencia, debido a una concepción errónea de la relación entre la unidad de la experiencia y sus partes. Veremos como cualquier consideración que propone describir o delimitar un objeto u evento supone la (...) comprensión de su unidad, la cual rebasa siempre la pretendida delimitación inicial.

FENOMENOLOGIA Y FISICA EN HUSSERL, WEYL Y NEELAMKAVIL: MATERIA-CAMPO BASADO EN EXTENSIÓN-CAMBIO Castillo Ochoa, Ruth Transferencias Interculturales e Históricas de la Europa Medieval Mediterránea RESUMEN La historia de la terminología científica posibilita dar cuenta de 'cambios lingüísticos' o contingencia de términos en Ciencia. La Fenomenología de Husserl resulta un marco filosófico completo para elucidar significados en terminología científica enfatizando el carácter a priori de conceptos fundacionales, su aspecto contingente (lenguaje), intersubjetividad, sujeto transcendental y epojé. En tal sentido, soportar las (...) nociones fundacionales en física bajo las categorías universales Extensión-Cambio de Neelamkavil contribuye al ideal husserliano. Aún no se llega a una imagen adecuada de las intricadas relaciones entre Filosofía y Ciencia. Sin embargo, los hallazgos científicos de Moser-Britt (2014) soportan posiciones kantianas y husserlianas en torno a los términos a priori que fundamentan las teorías físicas. Como consecuencia, los resultados han despertado el interés de filósofos y científicos hacia las ideas husserlianas en tanto terminología lingüística y comprensión aprioricista del mundo. De esta forma, dentro del estado actual del arte, P. Berghofer y H. Wiltsche (2018) abordan el rol de fenomenología en Filosofía de la Física; mientras J. Drummond (2019) en "Husserl: German Perspectives" analiza el rol de la fenomenología en Ciencia. R. Neelamkavil (2018) da cuenta de un nuevo conjunto de categorías en física que comulgan con las ideas de Husserl. La comprensión de los términos Masa y Campo en física, se aborda el estudio de H. Grelland "Husserl, Einstein y Weyl and Concepts of Space, Time and Space-Time" y H. Weyl, "Space, Matter and Time". Un análisis metalingüísitico entre términos científicos y fenomenológicos no se ha realizado aún.

SYMMETRY IN PHYSICS: FROM PROPORTION AND HARMONY TO THE TERM OF METALENGUAJE -/- Ruth Castillo Universidad Central de Venezuela -/- The revolutionary changes in physics require a careful exploration of the way in which concepts depend on the theoretical structure in which they are immerse. A historical reconstruction allows us to show how the notion of symmetry evolves from the definition as proportion and harmony to its consideration within the language of contemporary physics, as a linguistic meta-theoretical requirement in (...) physical theories. In contemporary terms, symmetry is a fundamental category of research to which the usual categories of the natural sciences can be reduce in: space, time, causality, interaction, matter, strength, etc ... Thus, symmetry is a concept with different meanings: heuristically symmetric models inspire scientists in the search for solutions to different problems. Methodologically, symmetric structures are use to make theories, laws with invariant properties. A description of nature in terms of symmetric structures and symmetry ruptures seems to be the proper way to describe the complexity of reality. (shrink)

Language exists because human subjects define themselves in the circumstance they are in. This is possible because they are able to know, not directly through their senses only, but adding something new to the construct they create in their conscience. The main thing they add to the construct created is categories, something invented or fabricated by the human subject at the moment of speaking.

Linguistics of saying studies language in its birth. Language is the mental activity executed by speaking subjects. Linguistics of saying consists in analyzing speech acts as the result of an act of knowing. Speaking subjects, speak because they have something to say; they say something because they define themselves before the circumstance they are in; and this is possible because they are able to know. Speaking, then, is speaking, saying and knowing. In this sense there is a progressive determination. Knowing (...) makes possible saying, and saying determines speaking. The problem thus is to determine the linguistic intention of the individual speaker to say something in every speech act. (shrink)

Some of the central questions that have been explored by Latin American and Latinx philosophers are questions of metaphilosophy. "Metaphilosophy" refers to philosophical reflections on the nature of philosophy itself. For example, we might ask: What is the purpose of doing philosophy? How does philosophy compare and contrast with other disciplines, such as science, theology, or literature? And what is the best way of categorizing the different kinds and traditions of philosophy? These are philosophical questions about philosophy as an activity (...) and as a discipline. In this chapter, we discuss some ways that Latin American and Latinx philosophers have addressed these and other metaphilosophical issues. Our focus will be on the following questions: What are the defining characteristics of Latin American philosophy and Latinx philosophy? Do they constitute distinctive traditions of philosophy, and if so, what is especially valuable about these traditions? (shrink)

INTRODUCTION. Today's fervent scientific and technological development needs to be governed by human values. Pedagogical and transhumanist discourses respond jointly to this purpose, in the face of a society that is in danger of both the abuse of progress and the renunciation of it. However, among the challenges of transhumanism are the possibilities of changing the most genuine condition of humanity. The deepest longings and the most important achievements require a controversial act of discernment present in every corner of current (...) education. METHOD. A hermeneutic-reflexive methodology has been used to carry out an exploratory analysis of the main implications of transhumanism, as an intellectual and cultural movement, in 21st century education. RESULTS. In the light of what has been studied, three axes can be distinguished: time, capacity and freedom. We live under parameters of instantaneity, fluidity and accelerated performance, but we advocate slowness for human flourishing; we long for the consecration of intelligence, but we fear losing what makes us unique; we foresee the end of our limits, but we risk chaining our freedom. DISCUSSION. The resulting discussion revolves around the crisis of postmodernity and the deep scepticism that emerges about one of the ends of education: our own reason; the soul of democracy.__________________________________________________________________________________________ _______________________________________________________________________________________________INTRO DUCCIÓN. El ferviente desarrollo científico y tecnológico actual necesita ser gobernado por los valores humanos. Los discursos pedagógicos y transhumanistas responden conjuntamente a este propósito, ante una sociedad que peligra tanto del abuso del progreso como de la renuncia al mismo. Sin embargo, entre los desafíos del transhumanismo se encuentran las posibilidades de modificar la condición más genuina de la humanidad. Los anhelos más profundos y los logros más importantes requieren de un controvertido acto de discernimiento presente en cada esquina de la actualidad educativa. MÉTODO. Se ha utilizado una metodología hermenéutica-reflexiva para llevar a cabo un análisis exploratorio de las principales implicaciones del transhumanismo, como movimiento intelectual y cultural, en la educación del siglo XXI. RESULTADOS. A la luz de lo estudiado se distinguen tres ejes: tiempo, capacidad y libertad. Vivimos bajo parámetros de instantaneidad, fluidez y rendimiento acelerado, pero abogamos por la lentitud para el florecimiento humano; anhelamos la consagración de la inteligencia, pero tememos perder lo que nos hace singulares; auguramos el fin de nuestros límites, pero nos arriesgamos a encadenar nuestra libertad. DISCUSIÓN. La discusión resultante gira en torno a la crisis de la postmodernidad y al profundo escepticismo que emerge sobre uno de los fines de la educación: nuestra propia razón de ser; el alma de la democracia._________________________________________________________________________________________ ___________________________________________HOW TO CITE / CÓMO CITAR: Castillo, P.

Speakers live language, that is, they intuit, create, acquire, perform, speak and say, interpret, use, evaluate and, even, speak of language. The real language is the language lived by speakers. On the contrary linguists, who at the same time are speakers and linguists, study language as something manifesting of front of them. In order to study language it is necessary to determine the degree of reality of the thing called language as the reality lived and used by speakers.

What are and where are the ethical limits of neuroeducation? The article reflects on a necessary question for the evolution of cognitive processes through critical deliberation, the delimitation of boundaries and the estimation of progress. On the one hand, it argues that the experimental turn could call into question the ethical and humanistic goal of education; on the other hand, it argues that a systematic renunciation of neuroscientific advances would also mean abandoning the quest for human flourishing. The humanities alone (...) do not provide the biopsychosocial approach from which we must understand our self-realisation. Thus, the first of the limits that is the origin of all the others arises from a scientific-humanist dilemma. The new boundaries to be delimited are the neuroscientific implications in themselves and how these are translated into educational, if they were to be valid in this field. Here neuromyths play an important role. It is precisely neuroethics as an applied ethics or branch of bioethics that takes up these aspects through neuroeducational ethics and educational neuroethics. In its fundamental branch, this discipline opens up the debate on moral neuroeducation. But the possibility of reducing morality and all that we are to our neural bases leads to new limits. To overcome them, he highlights the potential of a sociocultural and biological symbiosis with the notions of 'neuroculture' and 'proactive epigenesis'. Finally, the essay deliberates on the more speculative boundaries between what we are and our possibilities for understanding it on the basis of transhumanism. ____________________________________________________________________________________________________ ______________________________________________________________________________________________¿Cuále s son y dónde están los límites éticos de la neuroeducación? El artículo reflexiona sobre una cuestión necesaria para el devenir de los procesos cognitivos mediante la deliberación crítica, la delimitación de fronteras y la estimación del progreso. Su hilo argumental proyecta, por un lado, que el giro experimental podría poner en entredicho el objetivo ético y humanista de la educación; por otro lado, que una renuncia sistemática a los avances de las neurociencias supondría, igualmente, abandonar la búsqueda del florecimiento humano. Las humanidades solo no brindan el enfoque biopsicosocial desde el que hemos de entender nuestra autorrealización. Por ende, el primero de los límites que es origen de todos los demás surge dada una disyuntiva científico-humanista. Los nuevos confines a delimitar subyacen de las implicaciones neurocientíficas en sí mismas y de cómo estas se trasladan a la praxis escolar, si es que tuviesen validez en este campo. Aquí los neuromitos juegan un papel importante. Precisamente, la neuroética como ética aplicada o rama de la bioética recoge estos aspectos mediante la ética neuroeducativa y la neuroética educativa. En su rama fundamental, dicha disciplina abre el debate sobre la neuroeducación moral. Pero la posibilidad de reducir lo moral y todo lo que somos a nuestras bases neurales deriva en nuevos límites. Para superarlos, destaca el potencial de una simbiosis sociocultural y biológica con las nociones de ‘neurocultura’ y de ‘epigénesis proactiva’. Finalmente, el ensayo delibera sobre los límites más especulativos entre lo que somos y nuestras posibilidades para entenderlo en base al transhumanismo._____________________________________________________________________________________ ____________________________________________________________________________________________________ _______HOW TO CITE / CÓMO CITAR: Castillo, P.

When we speak of language we usually use the concept of a particular language. In this sense the concept denoted with the word language may vary from one language to another. Real language (=the language spoken) on the contrary is the reality lived by speakers thus encompassing complex and multifarious activities. Depending on the language spoken, the modes of thinking, modes of being in the conception of things, and systems of beliefs transmitted by means of particular languages, denote the living (...) reality of language with different grammatical categories. The concept “language” is expressed sometimes with a noun, thus denoting something existing in it; sometimes with a verb, thus denoting an action or an activity; and sometimes with an adverb, thus denoting the mode of an activity. The reality or degree of reality implicit in these grammatical categories involves a particular mode of thinking, prompted with a particular mode of being in the conception of things. Because of this it is necessary to distinguish the concept of language as something different from the reality of language. But first of all it is necessary to determine the reality or degree of reality of both the reality lived by speakers and the thing usually conceived of as language or a language. (shrink)

Reconstruying historically the beginning of development scientific thought in Venezuela, particularly in Physics, allow to account imperative need to preserve academic-scientific formation of Venezuelan society in 21st century. The Venezuelan historians Rafael Balza and Yajaira Freites in their respectively studies "Modern Physics in the Caraqueña Society of the late eighteenth century: between Mathematics and technique and "The problem of knowledge between hacendados and illustrated merchants of the province of Caracas-Venezuela (1793-1810)" allow to account efforts of Agustín de la Torre to (...) insert, in Venezuelan society of 18th century, teaching , research, divulgation and application of modern physical sciences initiated in Europe, marking the beginning of development of eighteenth-century Venezuelan technical and scientific thought. It should be noted that historical study of Agustín de la Torre is a complicated due to scarce documentation and cultural complexity of eighteenth-century Venezuela. The contribution of study is to account for risk of loss of Science in Venezuela in XXI century, through historical reconstruction around of Agustín de la Torre and his countless and tireless efforts to develop the study and application of physics experimental in Venezuela. The scope of this research is framed in the need to show the importance in the preservation of scientific talent. Studying the efforts in eighteenth-century Venezuela allows this. The historical study around Agustín de la Torre gives an account of the origin in the studies of physics and the complex situation within the scientific and social context to develop Science in Venezuela.

En las actividades ordinarias de nuestra vida cotidiana encontramos nuestros actos de percepción confrontados por las cosas materiales. A ellos ─actos de percepción─ les atribuimos una existencia "real" asumiéndolos de tal manera que los sumergimos y transfundimos, de forma múltiple e indefinida, dentro del entorno de realidades análogas que se unen para formar un único mundo al que yo, con mi propio cuerpo, pertenezco. Ahora bien sí frente a la cotidianidad descrita anteriormente asumimos una actitud escéptica acerca de lo que (...) es “real” en el mundo,nos descubriremos haciendo una reflexión filosófica. Bajo esta deliberación encontramos que, por ejemplo, la cualidad "verde", tiene existencia por medio de la sensación "verde"asociada a un objeto dado por la percepción, lo que nos lleva a pensar que no tiene sentido vincularla sensación como cosa en sí misma a cosas materiales existentes en sí mismos , esto nos lleva a pensar que las cualidades de los sentidostienen carácter subjetivo.A pesar de esta reflexión es conveniente acotar que esta subjetividad no interesaa las ciencias exactas ya que éstas procuran lo objetivo. -/- Desde este punto de vista,encontramos dentro de los estudios de Galileo Galilei el principio que subyace al método matemáticoconstructivo de nuestra física moderna ; de esta manera, y bajo este principio,los colores ─ por ejemplo “verde”─ son solo vibraciones en un medio repudiando de esta forma el carácter subjetivo a la vez que se mantiene la objetividad. Sin embargo, dentro del campo de la filosofía el idealismo transcendental de Kant marca un cambio de paradigma en relación a lo anterior. Kant sostiene que no solamente las cualidades de los sentidos tienen carácter subjetivo, sino que espacio y tiempo, conceptos fundacionales dentro de la física, no tienen significación absoluta; en otras palabras, espacio y tiempo son formas de nuestra percepción . Para Kant aquello que sustenta nuestra percepción y aquello que sustenta el conocimiento matemático aplicado a la experiencia son lo mismo: intuiciones puras a priori del espacio y el tiempo. De esta manera, y bajo esta perspectiva, sólo la teoría de la relatividad deja muyen claro que las dos esencias: espacio y tiempo, como formas de la intuición en términos kantianos, no tienen lugar en el mundo construido por la física matemática concebida por Galileo . -/- Según esto, los colores no son siquiera vibraciones en un medio sino simplemente una serie de valores de funciones matemáticas en las que se producen cuatro parámetros independientes que corresponden a las tres dimensiones del espacio y la del tiempo, expresado como principio general esto significa que el mundo real y cada uno de sus constituyentes con sus características sólo pueden ser, en términos husserlianos, objetos intencionales de actos de conciencia . En otras palabras: los datos inmediatos que recibo son las experiencias de la conciencia. Esto nos permite afirmar que la sensación de un objeto está presente de una forma físicamente real para mí con quien esa sensación se relaciona. Esto es lo que Brentano llama objeto intencional ;es así como al percibir un objeto, por ejemplo: veo este “libro” mi atención está totalmente dirigida hacia él. Yo "tengo" la percepción, pero sólo cuando hago de esta percepción ─ acto libre de reflexión ─algo que "conozco" con respecto a ella ─y no sólo el “libro”─ llego precisamente a un segundo acto: objetos intencionales de actos de conciencia, que son a los que referíamos antes . -/- El objeto intencional es inmanente y lo que es inmanente es absoluto ; es exactamente lo que es en la forma en que lo tengo, y puedo reducir esto, su esencia, por los actos de reflexión . En otras palabras, es un componente real de mis experiencias; contrario a lo que sucede con el acto primario de percepción, donde el objeto es trascendental , esto es, se da en una experiencia de conciencia pero no es un componente real de la misma. Por otra parte, los objetos trascendentales tienen sólo una existencia fenoménica; son apariencias que se presentan de múltiples maneras. Ninguno de estos modos de aparición puede pretender presentar aquello que percibimos – por ejemplo el libro- tal como es en sí, además en toda percepción está involucrada la tesis de la realidad del objeto que aparece en ella; este último es, de hecho, un elemento fijo y duradero de la tesis general de la realidad del mundo . En resumen, lo que interesa ver claramente es la importancia enel dato de la conciencia como punto de partida en el que debemos situarnos si queremos comprender el significado absoluto . (shrink)

Under the approach of basic concepts analysis and historical reconstruction, the evolution in meaning and use of symmetry, from the Greek world to the modern age is recognized, classifying it under the schemes of Branding-Castellani, R. Carnap and J. Roche. In this sense, two problems are studied: 1) the existence or not of the term symmetry in antiquity and 2) the Leibnizian position in reference to the understanding of the inertial problem and its repercussions in the evolution of the notion.

It has been said that all philosophy begins with a set of concerns and a set of intuitions. With this idea in mind, we ask: Would it be helpful to understand Mexican-American philosophy as a kind of philosophy that begins with the concerns and intuitions of the Mexican-American community? On this view, what distinguishes Mexican-American philosophy is the orientation from which the philosophical investigation proceeds. Such an orientation is shaped by the experiences and relationships that are characteristic of those who (...) identify as Mexican-American. We offer a list of concerns and intuitions that we suggest are widely held by the Mexican-American community. Focusing on questions surrounding linguistic assimilation in the U.S., we illustrate how beginning from these particular starting points might alter the way we think about philosophical issues.

Meaning as the original function of language is the arrangement of internal things on the part of the creative and historical individual subject who speaks a particular language. Meaning constitutes the series of contents making up the linguistic world human subjects can manage real things with. Real things are not described with meanings but merely represented and designated. Meanings represent the essence of things thus making them members of a category. In this sense, meaning is the base to create things (...) in as much as they constitute entities. Only through the operation of determination can meanings designate individual real things. Since meaningful categories are intended to particular purposes, meaning is intentional and inclusive. (shrink)

The current technoscientific progress has led to a sectorization in the philosophy of science. Today the philosophy of science isn't is informal interested in studying old problems about the general characteristics of scientific practice. The interest of the philosopher of science is the study of concepts, problems and riddles of particular disciplines. Then, within this progress of philosophy of science, neuroscientific research stands out, because it invades issues traditionally addressed by the humanities, such as the nature of consciousness, action, knowledge, (...) normativity, etc. As a result, the new area of interdisciplinary study of neuroscience and philosophy arises: neurophilosophy. This emerging area applies neuroscientific concepts to traditional philosophical questions, limiting their responses to neuroscientific revelations about nervous systems. Neurophilosophy research focuses on problems related to the indirect nature of mind and brain, computational or representative analysis of brain process, relationships between psychological and neuroscientific research, adequate adaptations of physical and philosophical concepts in neuroscience and the place of cognitive functions. Now, the temporal representation of conscious experience and the types of the neural architecture to represent objects in time have aroused scientific interest. Under these interests, we focus on the studies on the temporary triadic structure of phenomenological consciousness in Dan Lloyd and Rick Grush. From Grush’s studies, the importance of Kantian ideas for cognitive neuroscience emerges, due to the active way in which Kant conceived space and time as forms of intuition, within which the mind interprets its experience. Under this perspective, the theoretical arguments of Dennett-Kinsbourne and Eagleman-Sejnowski represent winks in the direction of Kant-Husserl within the neuroscientific goal while considering that the contents provided by the mind included space, objects and perception of causal relationships. Then, theories of cognitive neuroscience are beginning to suggest that these elements are also, as Kant argued, interpretative elaborations provided by mind / brain, and not only content received from outside. In other words, current cognitive neuroscientific theories try to pass from its Humean phase to a Kantian phase. So, the challenge has been to explain that these elements are provided by the mind and the world itself, and how they have the content they have come from. These are lacking in current studies. Filling this gap helps to involve the analysis of the scientist’s experience in his theoretical attitude. In this sense, an investigation under the Kantian-Husserlian approach that involves pure intuitions a priori with the experience of the scientific and neuroscientific concepts represents a ground-breaking. At present, a neurophilosophical study about this does not exist. In this sense, one feasible proposal for research would be based on the application of neuroscientific results of Moser-Britt to philosophical problems of foundational notions in relativistic physics: space, time, space-time, field, etc., under the Kantian-Husserlian approach, which allows to demonstrate the multidisciplinary link between neurophilosophy and physics. This represents a ground-breaking area in current interests in scientific research, with a positive impact in the field of neuroscience, and contributing to the study of abstraction emphasizing the importance of Kant’s Copernican turn and Husserl’s phenomenological ideas in the construction of physical theories. -/- .

The most comprehensive manifestation of language can be seen in the activity of speaking. In it the activity of speaking cannot be understood unless it is referred to the concepts of language and a language. Anything in language can be found in the activity of speaking. Because of this you can find what language is if you abstract from the innumerable manifestations of the activity of speaking.

El exilio de académicos y científicos venezolanos, representa un desastre para una colectividad emergente y joven dentro del país. La desatención a la comunidad académica venezolana en el exilio, puede llevar a una desconexión, pérdida y aislamiento de la Ciencia venezolana ─formada antes y durante los primeros años del periodo totalitario─ dentro del contexto nacional e internacional. Actualmente los intentos por mantener la cohesión de la comunidad académica venezolana en el exilio están fragmentados y desvinculados entre sí, lo que se (...) traduce en desaprovechamiento de las distinta iniciativas y perjuicio a la población académica-científica. No existe una adecuada organización que permita cohesionar a los académicos y científicos venezolanos en riesgo. Esta desorganización conlleva la “no integración” del talento venezolano académico-científico en programas internacionales en países de acogida. Y digo “académica” y no “científica”, porque la mayoría de programas e iniciativas internacionales están dirigidas solo ciencias exactas dejando de lado las ciencias humanísticas. Sin embargo, son las investigaciones humanísticas las que muestran el devenir de científicos exiliados. En los países que han sufrido regímenes totalitarios, guerras y/o situaciones de conflicto, el desvanecimiento de la investigación y acción humanística representa uno de los primeros objetivos. Es por esto, que he querido usar el término “Academia” en lugar de “Ciencia” ya que la primera acepción tiene un mayor radio de inclusión, evitándose posibles disertaciones positivistas y neopositivistas —desde el ámbito filosófico—en torno a lo que entendemos o categorizamos por “Ciencia.
