El presente trabajo plantea la necesidad de volver a la clásica distinción de conocimiento teórico y conocimiento práctico y repensar el lugar de la voluntad y la libertad humanas en el proceso cognoscitivo en general. Desde la consideración de la noción de conciencia, del valor dado a la dimensión cognoscitiva en el ámbito moral, la índole del conocer como relación con lo real y la idea de verdad, llegamos a la conclusión de que el planteamiento racionalista que excluye a la (...) fe como ajena al conocimiento lo hace por el mismo motivo por el que excluye a la voluntad: para evitar la necesidad de tener que decidir.

Reciprocity is ubiquitous in our lives, both as a way of rewarding and punishing others. Consequently, the social sciences have devoted many studies to this phenomenon. However, the concept of 'reciprocity' is quite polyvalent, and is used in many different ways across different disciplines - a situation potentially prone to equivocation, which hinders fruitful interdisciplinary work. At the same time, although philosophers often invoke 'reciprocity' in their work, there is a lack of conceptual clarification about what reciprocity actually means - (...) an eminently philosophical task. This thesis fills such a gap, by offering a general framework that allows us to understand how 'reciprocity' is used across different sciences. Such a framework consists in a grammar of several uses/meanings of reciprocity. Moreover, the thesis fills a second gap, regarding the correct interpretation of the psychological role of the reciprocity-motive in economic experiments. There has been a long-standing tradition in economics which overemphasizes the role of inequality aversion and downplays the role of reciprocity. Contrary to this deeply ingrained trend, I argue that reciprocity is the main motive of punishment of free-riders in the public goods game. My argument includes the first systematic critique of an experiment which is currently quite popular in behavioural economics. I show that the latter does not deserve the credit which it has received so far, and thus many economists need to revise their endorsement of inequality aversion. By offering a renewed interpretation of the motives in economic experiments, the thesis highlights reciprocity as a distinctive motivation. The thesis also offers tools to rethink key aspects of economic methodology, and proposes a distinction between prediction, explanation and rationalization of behaviour, in order to achieve psychologically realistic explanations of behaviour. The disciplinary home of the thesis is in philosophy of social science, economics and moral psychology. (shrink)

The purpose of the present study is to examine the attitudes of Portuguese chartered accountants with respect to questions of ethical nature that can arise in their professional activity. Respondents were asked to respond to the Ethics Position Questionnaire developed by Forsyth (Journal of Personality and Social Psychology 39(1), 175–184, 1980), in order to determine their idealism and relativism levels. Subsequently, they answered questions about five scenarios related to accounting practices, with the objective of measuring their ethical judgments. Based on (...) the idealism and relativism levels of our respondents, they were classified into one of four groups, representing different ethical ideologies (absolutism, exceptionism, subjectivism, and situationism). The results indicated that age was the major determinant of relativism. Contrary to previous research, older respondents revealed themselves significantly more relativistic than younger ones. Gender seems to be the most important determinant of ethical judgments; against expectations, men evidenced significantly stricter judgments than women in two of the five scenarios. Findings also indicated that respondents’ ethical judgments did not differ significantly based on their ethical ideology, supporting the idea that ethical ideology is not an important determinant of ethical judgments.

This article concerns a phenomenon of elementary quantum mechanics that is quite counter-intuitive, very non-classical, and apparently not widely known: a quantum particle can get reflected at a potential step downwards. In contrast, classical particles get reflected only at upward steps. As a consequence, a quantum particle can be trapped for a long time (though not forever) in a region surrounded by downward potential steps, that is, on a plateau. Said succinctly, a quantum particle tends not to fall off a (...) table. The conditions for this effect are that the wave length is much greater than the width of the potential step and the kinetic energy of the particle is much smaller than the depth of the potential step. We point out how the topic is accessible with elementary methods, but also with mathematical rigor and numerically. (shrink)

Journal Name: Semiotica Issue: Ahead of print.

The main purpose of this work is to provide a semiotic ontology for redescription of active cognitive externalism, recently developed by the paradigm 4E (embodied, embedded, enactive, extended cognition). In our approach, distributed cognitive systems (DCSs) are described as semiosis, signs in action. We explored the relationship between semiosis and cognition, as conceived by C. S. Peirce, in association with the notion of distributed cognitive system (DCS). We introduce Peircean externalist approach with an emphasis on the notion of temporal distribution (...) of semiosis, and describe DCSs, and their elements, as “sign in action”. To develop this argument, we describe an example of DCS -- verbal-musical improvisation of repente, repentismo, or viola singing. It is a phenomenon of verbal-musical improvisation that takes the form of a challenge in versified oral poetry. We describe the phenomenon as the embodiment of the formal structure of a cognitive task and an inferential process. This embodiment corresponds to a semiotization of the repente performances as DCSs. The temporally distributed tendency of repentismo organizes the DCS as a system that performs metasemiotic experiments on the action of signs. (shrink)

En este documento, debato ampliamente sobre la fenomenología de la intersubjetividad presentada por Husserl y por Sartre, centrándome en los conceptos de empatía y ser-para-otros. Contrariamente a la opinión más común, rechazo la objeción de solipsista dirigida a Husserl y sostengo que es la descripción de Sartre la que da lugar a esa objeción, en la medida en que él describe la conciencia de otro sujeto como una forma de autoconocimiento como un "objeto" (para "otros"). Termino señalando algunas directrices para (...) convertir el análisis de Husserl de la aprehensión de otros sujetos en una fenomenología de la comunicación del más alto nivel. (shrink)

We prove that every weakly square compact cardinal is a strong limit cardinal, and therefore weakly compact. We also study Aronszajn trees with no uncountable finitely splitting subtrees, characterizing them in terms of being Lindelöf with respect to a particular topology. We prove that the class of such trees is consistently non-empty and lies between the classes of Suslin and Aronszajn trees.

Scott Sehon argues that the conception of determinism employed in the Consequence Argument is implausible because it rules out the logical possibility of the laws of nature being violated. Sehon says, for instance, that determinism is incompatible with the logical possibility of an interventionist God. His objection to the Consequence Argument boils down to a way of reading the box in what is implied by van Inwagen's conception of determinism. Sehon reads the box as logical necessity, and this clearly precludes (...) the logical possibility of the laws of nature being violated. However, I argue that determinism as employed in the argument is not implausible. First, I try to show that it is legitimate to read the box of □ as either metaphysical or logical necessity depending on the account of laws that one assumes. If one accepts a fully Humean account of laws, then the box should be read as logical necessity. Nevertheless, I argue that this is not a problem for the Humean. On the other hand, if one reads the box as metaphysical necessity, which is mainly motivated by the dispositional account of laws and might be motivated by Armstrong's account, then determinism is compatible with the logical possibility of the laws being violated.

O envelhecimento da população, ou seja, o peso das pessoas mais velhas no conjunto da população, é uma tendência globalmente partilhada que resulta do fato de as pessoas viverem mais em consequência dos progressos realizados pela humanidade. Não se trata apenas do aumento do peso da população sênior. A extensão da longevidade tem implicado o reforço do grupo de idade mais avançada, a chamada “grande Idade”, colocando a taxa de crescimento do grupo com mais de 85 anos acima da do (...) grupo de 65 ou mais anos. Os seniores não são apenas mais numerosos como cada vez mais velhos. As fronteiras da vida são empurradas para mais longe, acarretando novos desafios para a sociedade. Um desses desafios é precisamente no campo dos direitos. Considerando que o envelhecimento se faz acompanhar por um aumento de situações de vulnerabilidade que podem afetar a dignidade humana, a questão dos direitos que assistem esse grupo é sem dúvida inadiável. À luz dos direitos humanos, o texto desenvolve uma reflexão a respeito dos direitos da “velhice” a partir de alguns documentos que têm proposto uma base para a sua formulação. Palavras-chave: Envelhecimento. Direitos humanos. Envelhecimento ativo. Idadismo. Participação social. (shrink)
