The aim of this study consists of postulating an ethical approach to Human Rights conceiving them as rights of the other, claiming that this approach represent a starting point for the development of a legal pluralism that contributes to the achievement of an effective and authentic peace. For this study is based on the premise that the law must be able to deal with the serious and still pending social and environmental problems that underlie the violations of human rights, especially (...) those of ecological nature. By way of conclusion, the need for a radical change of the paradigm is evidenced, for which a perspective of ethics as a linguistic praxis is proposed, since such praxis has the potential to inspire the reformulation of human rights, for the purpose of reversing the dynamics of violence imposed by the logic of identity underlying the current legal system.

We consider small-weight Cutting Planes (CP * ) proofs; that is, Cutting Planes (CP) proofs with coefficients up to $\operatorname{Poly}(n)$ . We use the well known lower bounds for monotone complexity to prove an exponential lower bound for the length of CP * proofs, for a family of tautologies based on the clique function. Because Resolution is a special case of small-weight CP, our method also gives a new and simpler exponential lower bound for Resolution. We also prove the following (...) two theorems: (1) Tree-like CP * proofs cannot polynomially simulate non-tree-like CP * proofs. (2) Tree-like (CP * proofs and Bounded-depth-Frege proofs cannot polynomially simulate each other. Our proofs also work for some generalizations of the CP * proof system. In particular, they work for CP * with a deduction rule, and also for any proof system that allows any formula with small communication complexity, and any set of sound rules of inference. (shrink)

We introduce new proof systems for propositional logic, simple deduction Frege systems, general deduction Frege systems, and nested deduction Frege systems, which augment Frege systems with variants of the deduction rule. We give upper bounds on the lengths of proofs in Frege proof systems compared to lengths in these new systems. As applications we give near-linear simulations of the propositional Gentzen sequent calculus and the natural deduction calculus by Frege proofs. The length of a proof is the number of lines (...) in the proof. A general deduction Frege proof system provides at most quadratic speedup over Frege proof systems. A nested deduction Frege proof system provides at most a nearly linear speedup over Frege system where by "nearly linear" is meant the ratio of proof lengths is O) where α is the inverse Ackermann function. A nested deduction Frege system can linearly simulate the propositional sequent calculus, the tree-like general deduction Frege calculus, and the natural deduction calculus. Hence a Frege proof system can simulate all those proof systems with proof lengths bounded by O). Also we show that a Frege proof of n lines can be transformed into a tree-like Frege proof of O lines and of height O. As a corollary of this fact we can prove that natural deduction and sequent calculus tree-like systems simulate Frege systems with proof lengths bounded by O. (shrink)

We extend results of Bonet, Buss and Pitassi on Bondy’s Theorem and of Nozaki, Arai and Arai on Bollobás’ Theorem by proving that Frankl’s Theorem on the trace of sets has quasipolynomial size Frege proofs. For constant values of the parametert, we prove that Frankl’s Theorem has polynomial size AC0-Frege proofs from instances of the pigeonhole principle.

We consider a modification of the pigeonhole principle, M P H P, introduced by Goerdt in [7]. M P H P is defined over n pigeons and log n holes, and more than one pigeon can go into a hole (according to some rules). Using a technique of Razborov [9] and simplified by Impagliazzo, Pudlák and Sgall [8], we prove that any Polynomial Calculus refutation of a set of polynomials encoding the M P H P, requires degree Ω(log n). We (...) also prove a simple Lemma giving a simulation of Resolution by Polynomial Calculus. Using this lemma, and a Resolution upper bound by Goerdt [7], we obtain that the degree lower bound is tight. Our lower bound establishes the optimality of the tree-like Resolution simulation by the Polynomial Calculus given in [6]. (shrink)

1. La política desde la ética -- 2. Problemas morales de las democracias.

Of all the thinkers of the century of genius that inaugurated modern philosophy, none lived an intellectual life more rich and varied than Gottfried Wilhelm Leibniz. Maria Rosa Antognazza's pioneering biography provides a unified portrait of this unique thinker and the world from which he came. At the centre of the huge range of Leibniz's apparently miscellaneous endeavours, Antognazza reveals a single master project lending unity to his extraordinarily multifaceted life's work. Throughout the vicissitudes of his long life, Leibniz (...) tenaciously pursued the dream of a systematic reform and advancement of all the sciences. As well as tracing the threads of continuity that bound these theoretical and practical activities to this all-embracing plan, this illuminating study also traces these threads back into the intellectual traditions of the Holy Roman Empire in which Leibniz lived and throughout the broader intellectual networks that linked him to patrons in countries as distant as Russia and to correspondents as far afield as China.

QUESTIONS DE METHODE I. Au contraire de Sartre qui, a partir de quelques elements cueillis dans les ecrits de HusserI concernant la conscience ima geante, a bllti sa propre doctrine de!'imagination, nous nous proposons de reconstituer, a partir de ces m~mes elements, ce qu'on pourrait appeler la theort:e husserlienne de l'imagination, c'est-a-dire la theorie que HusserI eut lui-m~me construite, s'il avait reuni en une synthese les elements qu'il a laisses epars. Une entreprise de ce genre est toujours delicate et souleve (...) des prob!emes difficiles - a commencer par celui de sa legitimite. N ous ecartons d'emblee l'objection d'ordre general qui contesterait Ie droit de systematiser dans l'reuvre d'un auteur ce que lui-m~me a laisse disperse et eventuellement inacheve. Par un tel scrupule, on sacrifie sans doute a la rigueur historique mais on est beaucoup moins soucieux de penetrer une pensee dans son dynamisme in terne et profond et, en derniere analyse, on protege les droits de l'archeologie mais non pas ceux de la culture et de son progreso Nous pensons a une difficulte beaucoup plus serieuse; de sa so lution depend l'attitude a adopter en face des textes dont nous devons nous servir dans notre etude. Nous utilisons des ouvrages qui couvrent la totalite de la car riere philosophique de HusserIl. (shrink)

The scientist Richard Lovell Edgeworth, educated at Trinity College, Dublin, and Oxford, was a Member of the Lunar Society of Birmingham, where he exchanged ideas with other scientists, including James Watt, and was known for his significant mechanical inventions. However, Edgeworth's real interest was education: in this 1788 two-volume work, written with his daughter, the poet Maria Edgeworth, he draws on his own experience of raising twenty children, from which the work derives its authority and innovative character. The work (...) was very influential, and led to his Essays on Professional Education. The two volumes discuss the theories of philosophers and educationalists, while in general arguing for the importance and formative character of early childhood experiences. Volume 1 deals with different areas of childhood education, including play, learning, and obedience and good behaviour. (shrink)

Despite many attempts to achieve an adequate definition of living systems by means of a set of necessary and sufficient conditions, the opinion that such an enterprise is inexorably destined to fail is increasingly gaining support. However, we believe options do not just come down to either having faith in a future success or endorsing skepticism. In this paper, we aim to redirect the discussion of the problem by shifting the focus of attention from strict definitions towards a philosophical framework (...) that allows conceiving of living systems as a natural kind, but whereby natural kinds are not to be defined by fixed necessary and sufficient conditions. We argue for a property-cluster kind approach according to which living systems constitute a natural kind with vague boundaries, capable of changing, and whose members do not need to instantiate every property. We draw from Boyd’s homeostatic property-cluster theory and introduce two modifications, one regarding homeostatic mechanisms and another related to the scientific role of kinds. Thus, our view overcomes some difficulties of Boyd’s theory and we are able to account for the natural kindhood of living things. We also emphasize the most appealing features of our approach for specific research fields and address three objections to this sort of approach. (shrink)

Ante ciertos modelos causales del agente libre inspirados en Tomás de Aquino, resulta interesante atender al modelo causal presentado por Tomás mismo, especialmente en un texto a partir del cual se puede rastrear la exposición de la acción libre como el efecto de los cuatro sentidos causales aristotélicos. Se trata de la cuestión sobre los actos imperados (ST I–II, q. 17); en cuyos primeros cuatro artículos –y en sus textos paralelos– determina que la voluntad es causa agente; la razón práctica, (...) causa ordenadora; y el imperium de ambas (razón y voluntad) se relaciona con el acto imperado como lo formal con lo material.

This paper aims to stablishes the sense in which propositions included under the perceptual use of ‘seeing-as’, developed by Wittgenstein in the Second Part of Philosophical Investigations, are justifiable from an epistemic point of view. To do this, first, it will be clarified the internal link between ‘visual experience’ and ‘interpretation’ for the type of mentioned cases. Second, it will be shown how the ‘seeing-as’ respects the rule-following paradox’s solution, as long as it does not presuppose any intermediary or need (...) anyone to account for what is perceived, highlighting the notions of ‘practice’, ‘familiarity’ and ‘context’ common both in the aforementioned solution and in the ‘seeing-as’ cases. Third, the general distinction between certainties or ‘hinges’ and ‘epistemic propositions’ presented by Wittgenstein in On Certainty will be applied to cases of aspect perception as a possible field of application of the so called Hinge Epistemology, showing how, in specific cases, the perceptual certainties that shape our way of life and that are groundless, can be recontextualized and merit reasonable justification.Keywords: Wittgenstein, aspect perception, seeing-as, hinges, certainty, justification.

Hilary Putnam is one of the world’s leading philosophers. His highly original and often provocative ideas have set the agenda for a variety of debates in philosophy of science, philosophy of mind and philosophy of language. His now famous philosophical thought experiments, such as the ‘Twin earth’ and ‘the brains in the vat’ have become part of the established canon in philosophy and cognitive science. _Reading Putnam_ is an outstanding overview and assessment of Hilary Putnam’s work by a team of (...) international contributors, and includes replies by Putnam himself. Divided into clear sections, it contains chapters on key aspects of Putnam’s large body of writing, including: Scientific realism and the changes that Putnam’s thought has undergone on this topic analyticity and ontology, including the important interconnections between the views of Putnam and Quine Putnam’s arguments concerning externalist views of meaning and reference, questions of conceptual relativity, and his preoccupation with ethics through a denial of the fact–value dichotomy Putnam’s developing views on perception. Offering an excellent survey of Putnam’s work, _Reading Putnam_ is essential for those studying philosophy of mind, philosophy of language, and philosophy of science, as well as for anyone interested in contemporary philosophy.

Asking students to generate a prediction before presenting the correct answer is a popular instructional strategy. This study tested whether a person’s degree of confidence in a prediction is related to their curiosity and surprise regarding the answer. For a series of questions about numerical facts, participants (N = 29) generated predictions and rated their confidence in the prediction before seeing the correct answer. The increase in pupil size before viewing the correct answer was used as a physiological marker of (...) curiosity, and the increase in pupil size after viewing the correct answer was used as a physiological marker of surprise. The results revealed that the pupillometric marker of curiosity was most pronounced if students were slightly more confident in their prediction than usual, and it was lower for predictions made with either very high or very low confidence. Furthermore, the results showed that high-confidence prediction errors and low-confidence correct responses yielded a pupillary surprise response, suggesting that highly unexpected results evoke surprise, independent of the correctness of the prediction. Together, results suggest that confidence in a prediction plays an important role in the occurrence of epistemic emotions such as curiosity and surprise. (shrink)

The placenta’s role as a mediating passage between bodies has been a conceptual resource for feminist theorists and philosophers interested in developing more nuanced explanations of the maternal–fetal relation, a relation that has tended to be identified with maternal and fetal bodies rather than with the placenta between them. I draw on efforts by philosopher Luce Irigaray and her readers to theorise placental relations as a model for the negotiation of differences. In her more recent work, Irigaray figures the placenta (...) as an enveloping space of metaphorical enclosure. The placental relation in Irigaray’s work thus offers insights into the temporal structure of her theory of becoming and can inform a more ‘materialist’ account of pregnancy. I then consider how placental relations are conceptual resources for re-imagining relations of self–other in pregnancy, and for addressing emergent ethical concerns over the transformation of the placenta into a scientific object.

Although perceptual grouping has been widely studied, its mechanisms remain poorly understood. We propose a neural model of grouping that, through top-down control of its circuits, implements a grouping strategy involving both a connection strategy (which elements to connect) and a selection strategy (that defines spatiotemporal properties of a selection signal to segment target elements and facilitate identification). We apply the model to a letter discrimination task that investigated relationships among uniform connectedness and the grouping principles of proximity and shape (...) similarity. Participants reported whether small circles formed a global letter E or H, and these circles could be connected by a line or be embedded in a matrix of squares. In the model, a good grouping strategy for this task consists of a connection strategy that connects circles but not squares for all conditions and a selection strategy that uses a selection signal of varying size, depending on whether squares were present. Consistent with empirical results, which were verified in two replication studies, model performance is worse with distractor squares, and line connectors improve performance only in the condition with squares. Rather than relying on abstract grouping principles, we show how the empirical results can be explained in terms of observers implementing a task-dependent grouping strategy that promotes overall performance.

Probability is the subject of considerable attention by Nagel, who devoted to it several writings. In the 1930s, Nagel put forward his “truth frequency” view of probability intended as a variant of the frequency theory minus the flaws to which this latter was susceptible. This paper illustrates how, according to Nagel, the issue of the meaning of probability should be addressed; Nagel’s criticism of the major interpretations of probability advanced in the literature, and the main traits of his “truth-frequency” theory.

The article is devoted to the study of the phenomenon of ideology in the context of its normative and regulatory function. The author's contribution to the further knowledge of the ideology was the following main conclusions. The emergence of ideology as a regulatory mechanism was primarily due to the transition from a traditional society to a modern one. Ideology is an attribute of modern society, since it acts as an intermediary between a person and social reality, determining and regulating the (...) activities of all people and relations between them in any sphere of society. In the XIX – first half of the XX centuries political ideology in its theoretical form dominated. As a regulatory mechanism, it functioned alongside religion, morality, and law, complementing them. In the second half of the XX – XXI centuries, as a result of the third STR, ideology in an ordinary and practical form became widespread. It began to replace the traditional regulatory mechanisms, surpassing them in the degree of influence on public consciousness and becoming the main mechanism of social regulation. (shrink)

Introduction: In 2020, according to the Global Cancer Observatory, nearly 10 million people died of cancer. Amongst all cancers, breast cancer had the highest number of new cases and lung cancer had the highest number of deaths. Even though the literatures suggest a possible connection between psychological factors and cancer risk, their association throughout studies remains inconclusive. The present systematic review studied the connection between psychological factors and the risk of breast and lung cancer, prior to a cancer diagnosis. The (...) psychological factors of trauma, grief, and depression were studied.Methods: The current systematic review was carried out across multiple databases in two phases, an initial exploratory research in June 2020, refined with a second electronic research in December 2020. The inclusion criteria included studies describing the association between trauma, posttraumatic stress disorder, grief, and depression with breast and lung cancer risk. The psychological data collection must have been carried out prior to a confirmed breast or lung cancer diagnosis, and accessed through self-report measures, questionnaires, clinical interviews, or clinical diagnoses. Study reports had to contain information about the incidence of cancer and effect size. The exclusion criteria were studies in which psychological factors were collected after cancer diagnosis.Results and Conclusion: A total of 26 studies were included. Although non-consensual, the findings from the present systematic review suggest that, in addition to the known risk factors, psychological factors may play an important role in the etiology of both breast and lung cancer. To include psychological factors as a variable that affects cancer development may be fundamental to opening new avenues for prevention and intervention.Systematic Review Registration: [www.ClinicalTrials.gov], identifier [CRD42020209161].

Corruption within the private sector has often not been dealt with in Brazil. Organizations may find corrupt acts in its operations or practices, but specific concepts and programs to avoid them are neither concrete nor clear. Some Brazilian stockholders have become aware of the risks involved in unethical procedures and are adopting the Best Practices of Corporate Governance initiative. International agencies have intensively supported organizations and governments in an effort to define policies that inhibit illegal or corrupt cultural habits throughout (...) the world, but Brazilian practitioners show insufficient response. Skepticism may indicate a lack of understanding about how an ethical leadership can guide employees, setting high standards for the organizational culture and climate, clearly defining limits of correct behavior, and creating appropriate codes of ethics. Transparency still has to be discovered as a significant tool to encourage professionalism in performance and reporting of data in Brazilian companies. In this article, we analyze the ethical behavior of the purchasing department of a multinational company in its host country, Brazil. It focuses specifically on the supplier–buyer relationship. The results indicate that despite the negative reputation Brazilians have in business ethics, a company can still develop a positive and ethical relationship with its stakeholders. Communication, transparency, compliance with the company’s code of conduct as well as the supplier’s awareness of the buyer’s code of conduct are the factors which influence the supplier–buyer relationship. Transparency can be used as a tool to reduce corruption, thereby increasing ethical behavior and company image. Good ethical behavior can help to build up a company’s image. (shrink)

El escrito continúa una discusión mantenida por Macarena Marey, María Julia Bertomeu y Nuria Sánchez Madrid en torno a la capacidad de los principios del republicanismo kantiano para transformar el espacio social en un ámbito en el que la autosuficiencia material constituya una de las condiciones fundamentales para que la igualdad formal ante la ley y la libertad política puedan actualizarse. En estas coordenadas se manifiestan también algunas discrepancias en lo concerniente a la percepción kantiana de las injusticias sociales y (...) políticas propias de su tiempo, si bien se alcanza el acuerdo de que el diseño institucional del republicanismo kantiano constituye un dispositivo conceptual suficiente para eliminar la desigualdad económica que comporta pasividad civil y política.

Émilie Du Châtelet is the only French woman author of a work included in the corpus of clandestine philosophical literature: a set of treatises, dissertations, or letters that circulated in Europe, and especially in France, mainly in manuscript form, during the seventeenth and eighteenth centuries, the main purpose of which was to subject religion to rigorous rational criticism (philosophical, historical, scientific). These Examens de la religion, one of the most controversial works in this corpus, circulated during the eighteenth century and (...) gave rise to a form of legend: sometimes said to be the work of Émilie Du Châtelet, sometimes the result of a form of collaboration between Du Châtelet and the one whose life she shared for a long time: Voltaire. If the feminine point of view on the Bible played a role in the recent attribution of this text to Émilie Du Châtelet, the existence of a properly feminine writing in the wider context of clandestine philosophical literature can now be discussed. This article aims to put this debate into perspective, at both the methodological and philosophical level. (shrink)

This article examines Sartre’s works in which his attempt to find an existentialist ethics is evident. Most of the clues to this project are to be found in texts published posthumously since during his lifetime he never managed to fulfil the promise he made at the end of Being and Nothingness. It will be argued that this existentialist ethics owes a strong debt to Kantian philosophy, even if it confronts more directly the historical dynamics of violence and oppression. Despite the (...) fact that this project is unfinished and only sketched out, it is possible to ask what Sartre’s direction of development would have been, pointing to the outline of a normative theory, Critical Existentialism, that could have its place in contemporary ethical debate.
