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)

We present a bibliography of Francisco Miró Quesada Cantuarias’ works divided by subject and subdivided by work type, and compare it with the last version of that made by Sobrevilla.

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.

This paper discusses the question of whether politics and ideology could ever be considered sensible sources for logical evidence. After discussing some proposals for this possibility, I answer negatively by arguing that any attempt to deviate from classical logics on these grounds would consist of an ad hoc denial of a logic principle.

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 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.

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.

In this paper, I propose a formal framework for modelling the process of testing empirical statements, hypotheses, theories, and research programmes. Unlike the diverse forms of falsificationism, this framework does not require any commitment to classical logic or to any specific system of logic, as it aims to be useful regardless of the logic we presuppose. On this regard, the paper will focus on how this framework applies to two logical contexts: the classical and the paraconsistent contexts. I will show (...) that this framework converges with falsificationism for consistent classical theories, and that it has very interesting consequences for the variety of paraconsistent cases. Concerning the latter cases, what may be called "empirical dialetheism" will be severely undermined as I will show that not even in our quite liberal framework it is possible to reject an "observable contradiction.". (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)

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)

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 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)

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)

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.

The concept of topic-neutrality, though central to contemporary characterisations of logic, lacks a standard formal definition. I propose a formal reconstruction of topic-neutrality in terms of a topical partition of atoms and its applicability across consequence relations. I explore the implications of this reconstruction for logical pluralism and monism, distinguishing between topic-neutral and topic-specific variants of each. I argue that while topic-neutral pluralism posits various applicable consequence relations across domains, topic-specific pluralism holds that some relations are applicable only to specific (...) domains.

Priest's theory of motion is based on Leibniz's Continuity Condition (LCC), which states that any state that exists at each instant in a continuous set of moments also exists at its temporal limit. If we accept the CCL, a free-falling pen would have to be simultaneously in motion and at rest at the instant of change: the critical moment when it hits the ground, thus passing from the state of motion to that of rest. This seems to be a contradictory (...) state of affairs, which is precisely what Priest claims to be the case. In this article, I discuss the logical possibility of empirically testing whether such a contradictory state of affairs occurs. (shrink)

“Literature and the Right to Death” is probably the most quoted of French thinker Maurice Blanchot’s texts. For decades it has been discussed by such important figures as Emmanuel Levinas, Jacques Derrida, or even the writer Paul Auster. Its importance is twofold: on the one hand, it is often considered an important gateway to Blanchot’s literary thought. On the other hand, it constitutes a substantial example of the new reception of Hegel in France after the Second World War. Although there (...) is no doubt about its Kojèvo-Hegelian inspiration and its center in what we could call “literary experience”, this article intends to explore another of its layers: its relation to the discussion around humanism and the Terror, as forgotten as it was central in France at the end of the 1940’s. We will thus try to lay the foundations for a new reading of this fundamental piece in Blanchot’s production. (shrink)

Maslow’s Human Motivation extended Theory, in its late version, proposed transcendence as one of the highest levels, inclusive or holistic in the Human consciousness. Through Meaning Theory, Victor Frankl and Paul Wong suggested that self-transcendence is a fundamental expression of our spiritual nature and a distinctive concept. However, it is not clear whether at present, with an extensive offer of individualistic currents, transcending involves a personal issue or is rather a collective issue, related to community and culture. The objective of (...) this research is to determine if seeking personal transcendence and seeking collective transcendence are two differentiable categories, and if there is a priority among them, which would suggest an extension of the Theory. With the participation of 402 business students in Mexico, and with the help of a structured equation model, it was determined that there is a significant difference between orientation toward “I transcend” and the orientation toward “I help others transcend.” The results obtained from the selected sample indicate that individual transcendence and collective transcendence are distinguishable categories. In addition, it was found that young people prefer to seek a personal meaning rather than a collective one, which suggest that dimension of collective transcendence is prior to personal transcendence. These findings can be used to design job profiles for positions that require staff development, and it can serve as a positive pattern for life education and society. (shrink)

The text attempts to look upon globalization in the education as a problem, referring to the governmental strategy that guaranties the control and the social development beginning from a modernization project that is not determined. Therefore, when taking into account as a frame of reference the centuries XIX and XX, it is shown the ‘education role’ as a control mechanism in permanent relation with the public politics and it is questioned its apparent liberal character.

One problem that various thinkers have studied is the relationship between culture and social development. This article will try to explain the principal characteristics of South Korean culture and its Confucian heritage as positive factors in the development of South Korea. To do so, it addresses the existence of values of Confucian origin in government and society. Next, the article reviews historical factors that played an important part in South Korean development. Finally, the authors reach the conclusion that development is (...) possible in distinct cultural contexts, and that it is not possible to establish a deterministic connection between a specific social framework and the conditions of social development.

A obra apresenta uma discussão sobre o sentido da democracia e sua relação com os padrões de dominação presentes na sociedade. A ordem democrática liberal não pode ser entendida como a efetiva realização dos valores que promete, pois a igualdade entre os cidadãos, a possibilidade de influenciar as decisões coletivas e a capacidade de desfrutar de direitos são sensíveis às múltiplas assimetrias que vigoram na sociedade. Porém, tampouco pode ser lida segundo a crítica convencional às "liberdades formais" e à "democracia (...) burguesa", que a apresenta como mera fachada desprovida de qualquer sentido real. Assim, a democracia não é um ponto de chegada, e sim um momento de um conflito que se manifesta como sendo entre aqueles que desejam domá-la, tornando-a compatível com uma reprodução incontestada das assimetrias sociais, e quem, ao contrário, pretende usá-la para aprofundar contradições e avançar no combate às desigualdades. Portanto, o conflito na democracia é um conflito também sobre o sentido da democracia, isto é, sobre quanto ela pode se realizar no mundo real como projeto emancipatório e quanto as instituições vigentes contribuem para promovê-la ou para refreá-la.

In 1967 I began writing this book in New York as an analysis of what had been enunciated in the visual arts, conditioned between technology and rebellion. When I return to Buenos Aires I continued to write (until 1972) in a different context where rebellion had revolutionary cravings for the prevailing dictatorship. In the early 1970s, very tough times began in our country (Argentina) and in Latin America in general. For that reason, I didn't publish it. It is now unquestionable (...) that what this work called "militant thinking of change" begins to develop again: the creative and answering act first and foremost in action. Its development in certain fields such as the feminist revolution, ecological awareness and the assessment of free sexual choice are manifestations of a cultural revolution. For this reason, publishing [this book] today makes sense again even if it was written half a century ago. The coordinator of the Centro Cultural de la Cooperación, Juan Pablo Pérez, wrote the appendix of the book and is the result of a series of reflections that occupied Luis Felipe Noé during his stay in New York and on his return to Argentina, between 1967 and 1972. The book was written in a period of estrangement from painting, overturned to intense writing at a time of crisis, which led Noé to another type of intellectual, political and theoretical production.

The rating of perceived exertion can be used to monitor the exercise intensity during laboratory and specific tests, training sessions, and to estimate the internal training load of the athletes. The aim of the present study was to develop and validate a specific pictorial perceived exertion scale for soccer players called GOAL Scale. The pictorial GOAL Scale was validated for twenty under-17 soccer players. In the validation phase, the athletes were evaluated in a progressive protocol involving stimuluses of 3 min (...) with 1 min for the rest into the stages until the voluntary exhaustion in Maximal Cardiopulmonary Effort Test, and in the Yo Yo Intermittent Recovery Test – Level 1. The RPE identified by the GOL Scale, by the Borg Scale 6 – 20 and by the Cavasini Scale, as well as the heart rate, perceptual of the heart rate and the blood lactate concentration were immediately evaluated after each stage of both tests. Spearman’s correlation coefficient was used. Construct scale validity was examined by regressing GOAL Scale against Borg Scale 6 – 20 and Cavasini Scale and concurrent scale validity was investigated by regressing GOAL Scale against HR, beats/min and blood lactate concentration during two progressive tests. There was a significant correlation values of the GOAL Scale with Borg Scale, Cavasini Scale, %HRmax, HR and lactate during tests. The results evidenced concurrent and construct validity of the GOAL Scale across a wide range of exercise intensity. The absence of verbal anchors makes the use of this instrument to soccer, futsal and beach soccer athletes of different languages and different literacy levels possible. (shrink)

BackgroundMonitoring recovery–stress balance in sport is becoming more relevant to prevent training maladaptation and reach the optimal performance for each athlete. The use of questionnaires that identify the athlete’s recovery–stress state have much acceptance in sports due to reliability and useful, furthermore for its low cost. Identifying possible differences between sport modalities and sex is important to determine specific needs and possible intervention ways to keep a recovery–stress balance. The aim was to analyze the differences in the recovery–stress state and (...) mood states by sex and sport type during the competitive phase in young Mexican athletes. As a secondary objective, the psychometric properties of the Mexican version of the Recovery–Stress Questionnaire for Athletes were analyzed.MethodsA cross-sectional study was carried on with 461 athletes, 17.95 years old, from six sports disciplines. The RESTQ-Sport and Profile of Mood States were applied in a single moment. Differences by sex and sports modality were analyzed. RESTQ-Sport’s confirmatory factor analysis was performed after the stress and recovery theoretical structure of two stress and two recovery dimensions, and last, the concurrent validation with the POMS was carried on.ResultsSignificant differences by sex were found in the General Recovery and Sport Stress dimensions of the RESTQ-Sport as well as Vigor factor of the POMS, being higher for men; furthermore, both the Sport Recovery dimension of RESTQ-Sport and Cholera and the Fatigue and Depression factors from POMS also had differences by sport type, showing a less recovery and high stress for individual sport athletes. Goodness-of-fit indexes of the model for the RESTQ-Sport were acceptable. Pearson’s correlation between questionnaires was moderate.ConclusionThe recovery–stress state shows differences in the function of sex and sport modality. More special attention is suggested for women and individual sport athletes. The higher punctuation for men compared with women in sport stress dimension did not negatively affect the recovery–stress balance for male athletes. Finally, the Mexican context adaptation of the RESTQ-Sport provides a psychometric instrument suitable to assess the recovery–stress balance in Mexican athletes. (shrink)
