The objective of this paper is to present the truth tables method of the propositional calculus of Tractatus Logico-Philosophicus as a result of computational procedures involving recursive operations in mathematics, since the secondary literature that is involved with such a problem fails to demonstrate such aspect of the work. The proposal is to demonstrate the base calculation of the truth operations as a consequence of the application of mathematical resources that involve the notion of recursivity, inspired both in the natural (...) numbers as well as in the factorial calculus, as well as in the procedures recommended by the combinatorial analysis and the calculation of probability. It is hoped, therefore, to present the truth operations of the propositional calculus as coming from the application of arithmetic to the logical resources. (shrink)

Esse artigo expõe as principais características das filosofias do dever moral e daquelas que explicam a ação humana a partir do sentimento moral. Essas filosofias são opostas em muitos pontos, mas coincidem na contraposição entre sentidos e razão humanos. Ambas as propostas filosóficas têm repercussões na Ética, no Direito e na Pedagogia, os quais acabam recebendo forte influência racionalista ou sentimentalista. Confrontamos esses dois sistemas com a atual “Ética das Virtudes”, a qual pretende sair do impasse surgido do debate entre (...) as duas teorias anteriores a partir do redescobrimento de pensadores como Aristóteles e Santo Tomás de Aquino. Atualmente, a Ética das Virtudes assume a colaboração de pesquisadores de diversas ciências contemporâneas, tais como a Sociologia, a Neurociência e a Filosofia Política. (shrink)

At workplaces where nanomaterials are produced or used, risk assessment and risk management are extremely difficult tasks since there is still limited evidence about the risks of nanomaterials. Measurement methods for nanoparticles are contested and safety standards have not yet been developed properly. To support compliance with the legal obligation of the employer to care for safe workplaces a large number of ‘soft’ regulatory tools have been proposed (e.g. codes of conduct, benchmarks, standards). However, it is not clear whether and (...) under which conditions soft regulation is complied with. This article discusses the potential advantages and drawbacks of soft regulation. It explores compliance issues when exposure measurement devices and other technology-related factors are involved. The exploration of three examples of soft regulation on occupational health and safety (a ministerial recommendation on preliminary exposure benchmarks, a nano-specific guidance of a chemical company and a public–private OHS guideline) shows that the capacity of the regulated parties to comply depends on the availability of appropriate technological devices and methods, technical expertise and other resources. When technological prerequisites are met, compliance is likely to increase. (shrink)

In order to understand how Deleuze's method of dramatization is ‘not privileging mankind in any way’, this article turns to the figure of the marionette as it is discreetly, but consistently, developed thorough Deleuze's books. Inspired by Kleist's On the Marionette Theatre, this marionette figure claims for a rhizomatic approach to the subject, defined by the lines it draws into space and exercising its freedom in the present of Aion through spatio-temporal dynamisms similar to those of Leibniz's monads. The strange (...) freedom developed by marionettes also leads to an examination of Nietzsche's ‘eternal return’, which is at the core of Deleuze's elaboration of the method of dramatization. Combining Nietzsche's eternal return with the characteristics of Deleuzian marionettes then requires us to revisit the famous concept of ‘becoming’: becomings are selective, both methodologically and ontologically.

Individuals exposed to dieting-related environmental cues have been repeatedly shown to be better able to resist tempting food. This especially applies to restrained eaters who hold a chronic dieting goal. Thus far, mainly short-term effects of environmental dieting cues have been examined and the individuals were typically unaware of being influenced. Yet, it is unclear whether individuals can deliberately apply environmental dieting cues for themselves to facilitate the pursuit of the longer-term goal of losing weight. The present longitudinal study applied (...) a 2 × 2 between-subjects design for 6 months. Our results provide preliminary indications that cue, awareness, and restrained eating interact. The results suggest that high restrained eaters could deliberately apply environmental dieting cues for themselves to facilitate losing weight. However, further studies are needed to explore the effects of environmental dieting cues over a longer period of time. (shrink)

The principle of energy conservation is widely taken to be a se- rious difficulty for interactionist dualism (whether property or sub- stance). Interactionists often have therefore tried to make it satisfy energy conservation. This paper examines several such attempts, especially including E. J. Lowe’s varying constants proposal, show- ing how they all miss their goal due to lack of engagement with the physico-mathematical roots of energy conservation physics: the first Noether theorem (that symmetries imply conservation laws), its converse (that conservation (...) laws imply symmetries), and the locality of continuum/field physics. Thus the “conditionality re- sponse”, which sees conservation as (bi)conditional upon symme- tries and simply accepts energy non-conservation as an aspect of interactionist dualism, is seen to be, perhaps surprisingly, the one most in accord with contemporary physics (apart from quantum mechanics) by not conflicting with mathematical theorems basic to physics. A decent objection to interactionism should be a posteri- ori, based on empirically studying the brain. (shrink)

One of the most serious challenges (if not the most serious challenge) for interactive psycho-physical dualism (henceforth interactive dualism or ID) is the so-called ‘interaction problem’. It has two facets, one of which this article focuses on, namely the apparent tension between interactions of non-physical minds in the physical world and physical laws of nature. One family of approaches to alleviate or even dissolve this tension is based on a collapse solution (‘consciousness collapse/CC) of the measurement problem in quantum mechanics (...) (QM). The idea is that the mind brings about the collapse of a superposed wave function onto one of its eigenstates. Thus, it is claimed, can the mind change the course of things without violating any law figuring in physical theory. I will first show that this hope is premature because energy and momentum are probably not conserved in collapse processes, and that even if this can be dealt with, the violations are either severe or produce further ontological problems. Second, I point out several conceptual difficulties for interactionist CC. I will also present solutions for those problems, but it will become clear that those solutions come at a high cost. Third, I shall briefly list some empirical problems which make life even harder for interactionist CC. I conclude with remarks about why no- collapse interpretations of QM don’t help either and what the present study has shown is the real issue for ID: namely to find a plausible integrative view of dualistic mental causation and laws of nature.

La Universidad de París en la Europa de finales del siglo XIII fue centro de acaloradas discusiones acerca del alma del hombre. La cuestión del alma es el punto doctrinal central y se muestra decisivo porque en la resolución de este único punto puede verse el trasfondo antropológico y metafísico de toda una cosmovisión filosófica e incluso teológica del universo. Una de las más problemáticas cuestiones que se plantearon acerca del alma es el problema de la unidad del intelecto para (...) todos los hombres. Parecería contradictorio pensar que todos los hombres piensan con un único intelecto, pero a su vez suena absurdo afirmar que un principio espiritual, inmaterial, se una a un cuerpo por un tiempo determinado para luego separarse. Ambas posiciones surgen de la consideración de nuevos textos llegados a las manos de los pensadores parisinos a través de autores árabes: los textos del De anima de Aristóteles. (shrink)

Citizen participation today needs to be understood as both an empowerment practice to create urban futures as well as the perpetuation of entrepreneurial and neoliberal modes of planning. The exponential progress of technologies and the digitalisation of everyday life have led to a surge of innovation. Since hybridity has become a key factor, citizen participation now involves citizens and governments meeting online and offline in a multi-stakeholder setting to plan the city in parallel layers, often according to controversial or even (...) contradictory logic (Horelli et al., 2015). As digital citizen participation opens up new tools and means to mobilise people and shape urban futures, this chapter analyses these new aspects through the categories of top-down/bottom-up participation as well as formal/informal practices. Using four case studies comparatively, our aim with this chapter is to find a new theoretical basis and contextualisation for digital citizen participation. The case studies are situated across Europe and North America: we study participatory budgeting in Helsinki, digitalising citizen participation in Lubbock, Texas, the National Map of Security Threats in Poland, and digital placemaking by a grassroots movement in an urban planning participation process in Zürich, Switzerland. The findings of the article show that (1) digital citizen participation fosters novel multi-actor networks negotiating governance of the urban space, (2) studies of citizen participation need to acknowledge the multi-layered hybridity and (3) new modes of governance enable novel senses of informality in participation.

‘Hated in the Nation’ invites us to reflect about our social media responsibility: in this episode, the hashtag #DeathTo sends a swarm of killing bee‐drones to the most unpopular candidate of the day. But, although there are no tiny bee drones yet in real life, it is not uncommon to shame someone online for a variety of reasons, and the consequences can be life‐changing. But, is this online trial truly fair? In this chapter I take some central points from the (...) philosophy of John Rawls and Hannah Arendt to explore under what conditions these online trials might be adequate. (shrink)

The choice to pursue fertility treatments is a complex one. In this paper I explore the issues of choice, agency, and gender as they relate to assisted reproductive technologies (ARTs). I argue that narrative approaches to bioethics such as those by Arthur Frank and Hilde Lindemann Nelson clarify judgments about autonomy and fertility medicine. More specifically, I propose two broad narrative categories that help capture the experience of encounters with fertility medicine: narratives of hope and narratives of resistance. This narrative (...) typology captures the inevitable conflict that women feel when they become subjects of fertility medicine. On the one hand, they must remain hopeful; on the other, they must not surrender themselves completely. Nelson's account of counterstories as narratives of resistance helps us see how women can reconcile the experience of a strong desire to have children with the desire to remain authentic and whole.

A Short Modern History of Studying Sacrobosco’s De sphaera. The treatise generally known as De sphaera offered at the beginning of the 13th century a general image of the structure of the Cosmos. In this paper I’m first trying to present a triple stake with which this treaty of Johannes de Sacrobosco (c. 1195 - c. 1256). This effort is intended to draw a context upon the treaty on which I will present in the second part of this paper namely, (...) a short modern history of studying this treaty starting from the beginning of the 20th century up to this day. The first stake consists in the well-known episode of translation of the XI-XII centuries in the Latin milieu of the Greek and Arabic treaties. The treatise De sphaera taking over, assimilating and comparing some of the new translations of the texts dedicated to astronomy. The second consists in the fact that Sacrobosco`s work can be considered a response to a need of renewal of the curriculum dedicated to astronomy at the University of Paris. And the third consists in the novelty and the need to use the De sphaera treatise in the Parisian University’s curriculum of the 13th century. (shrink)

Background: Mismatch between the perception of one’s moral duty and one’s real social contribution may trigger moral distress, especially when no specific resistance strategies are used to counteract morally distressing situations. Considering a philosophical-ethical conception, individuals need to first reflect upon themselves to later turn to the world and confront their current situation in order to change it. Objectives: To understand moral distress experienced by nursing professors teaching in higher education institutions and the use of parrhesia as a coping strategy. (...) Method: This qualitative exploratory-descriptive study addressed 33 nursing professors working in Brazilian federal public universities using an open-ended question form. Data were collected between June and December 2018 and analyzed using discursive textual analysis. Ethical considerations: The Institutional Review Board at the Federal University of Rio Grande approved this study. Findings: Three categories emerged: performance of nursing professors and potentially distressing situations, the experience of moral distress, and parrhesia as a strategy to deal with moral distress. Nursing professors face situations that cause moral distress in the context of higher education, however, those who adopt parrhesia as a coping strategy find it easier to express their beliefs from the perspective of moral duty, even in the face of conflicts. Conclusion: When the nursing professors in this study acknowledge elements in the power structure that hinder their actions, they express parrhesia, as an essential virtue in an attempt to modify unsymmetrical power relations that can trigger moral distress.

This commentary addresses the concept of learning stemming from Eva Jablonka and Simona Ginsburg’s theory of the emergence of consciousness. Jablonka and Ginsburg find strong support in biosemiotics for their argument that learning offers an evolutionary transition marker for the emergence of consciousness. Indeed, biosemiotics embraces a view on evolution that integrates both phylogeny and ontogeny. It does not polarize learning and evolving. At the same time, Jablonka and Ginsburg’s argument gives both biosemiotics and learning theory a shake, forcing scholarship (...) in these fields to tackle difficult questions on agency, selfhood, consciousness and anthropological difference. I explore some of the main questions that arise from this theoretical development, particularly in reference to Andrew Stables’ semiotic learning theory, which has been easily nested in a biosemiotic framework.

The recent development of biosemiotics has revealed the achievement of knowledge and the development of science to be the results of the semiosis of all life forms, including those commonly regarded as cultural constructs. Education is thus a semiosic structure to which evolution itself has adapted, while learning is the semiotic phenomenon that determines the renewal of life itself. Historically, it was a semiotic paradigm that determined the emergence of institutions such as universities and that underpinned the development of liberal (...) education. The present article considers the history of education in terms of sign emergence and evolution, regarding education as currently being conceived and practised as a stage in the general evolutionary action of signs. This approach differs from the prevailing modern approaches to education, which are mostly applied psychology and sociology. (shrink)

Desde o início da teorização freudiana, inibição, defesa e censura são processos que devem incidir sobre as pulsões. O primitivo pulsional precisa ser reprimido ou transformado. Este artigo problematiza a relação entre as pulsões sexuais e a defesa psíquica, ao longo do período pré-psicanalítico e da primeira tópica freudiana. Situamos o conflito entre sexualidade e repressão, apontado por Freud como característico das psiconeuroses, enquanto que nas neuroses atuais a angústia está relacionada a um registro quantitativo e não exatamente a um (...) conflito psíquico. Nesse caso, revela-se desencontros entre um sexual corpóreo e sua representação psíquica. Pretende-se, neste trabalho, evidenciar o caráter negativo das pulsões e pôr em relevo a natureza do antagonismo que se opõe às pulsões sexuais. A formulação das pulsões de autoconservação como aquilo que deve se contrapor às pulsões sexuais não esclarece completamente porque é imperativo que algo aconteça face às vivências pulsionais fundantes do aparelho. A satisfação em estado bruto acarreta prejuízos, tanto do ponto de vista psíquico quanto social; logo, a repressão das pulsões sexuais é condição necessária para a existência individual e coletiva. Evidencia-se assim algo específico do humano, afinal, se toda a natureza funciona afirmando o instinto, a espécie humana somente se desenvolve a partir de sua negação. A partir de tais construções teóricas, questiona-se se a psicanálise ainda permanece demasiadamente tributária de uma concepção de natureza revestida de pressupostos morais, sustentando a noção de que tenha que ser continuamente negada, afastada, coagida e domesticada, em prol de construções sociais bastante questionáveis, porém acatadas como necessárias.

This paper explores a semiotic notion of body as starting point for bridging biosemiotic with social semiotic theory. The cornerstone of the argument is that the social semiotic criticism of the classic view of meaning as double articulation can support the criticism of language-centrism that lies at the foundation of biosemiotics. Besides the pragmatic epistemological advantages implicit in a theoretical synthesis, I argue that this brings a semiotic contribution to philosophy of mind broadly. Also, it contributes to overcoming the polemic (...) in linguistics between, loosely put, cognitive universalism and cultural relativism. This possibility is revealed by the recent convergence of various semiotic theories towards a criticism of the classic notion of meaning as double articulation. In biosemiotics, the interest to explicate meaning as multiply articulated stems from the construal of Umwelt as relying on the variety of sense perception channels and semiotic systems that a species has at its disposal. Recently, social semiotics developed an unexplored interest for embodiment by starting from the other end, namely the consideration of the modal heterogeneity of meaning. To bridge these notions, I employ the cognitive semantic notion of embodiment and Mittelberg’s cognitive semiotic notion of exbodiment. In light of these, I explore the possible intricacies between the biosemiotic notion of primary modeling system and concepts referring to preconceptual structures for knowledge organization stemming from cognitive linguistics. Further, Mittelberg’s concept of exbodiment allows for a construal of meaning articulation as mediation between the exbodying and embodying directions of mind. (shrink)

Prior to having its authenticity and transparency examined the openness of human existence may be said to need preservation as is, regardless of its receptivity and responsiveness to the truth of Being. Paradoxically, in self-sacrifice the fulfilment of Dasein’s ownmost potentiality-for-being is dependent upon a most radical disowning of itself. This investigation approaches self-sacrifice on the basis of its analogy with the creation of the work of art – as the peculiar fixation of the existing, already disclosed world of everydayness (...) within Dasein’s final absence. Finally, the suggestion is made that the incommensurable greatness of the heroic self-sacrifice needs to be itself preserved from the degradation brought about by massive and compulsive reproduction.

ObjectivesQuality of Life depends on the discrepancy between desired and current experiences, thus in chronic illness, adjustment of expectations and interpretation of the current situation are crucial. Depression is known to influence this gap, and the present study aims to further assess the role of resilience and health locus of control.MethodsA total of 94 patients with neurological disorders were screened via telephone regarding depression, resilience and HLC. Current and desired state of several life domains were assessed, such as Fitness, General (...) Health, Pain, Daily Activities, Finances, Leisure, and Family. Elastic net regularization and analyses of variance were used to disentangle the impact of depression, resilience, HLC, and sociodemographic factors on the perception of current and desired state, and the gap between both.ResultsA gap was present for all domains but largest for pain. Interpretation of the current state was linked to desired state, HLC, and age. All gaps were related to depression; certain domains were in addition influenced by resilience, HLC and sociodemographic factors. Of note, for most domains, patients did not select the highest possible desired state.ConclusionOlder patients with neurological disorders report a gap between current and desired state for many aspects of life. Adjusting expectations is beneficial in the face of declining health, but a reasonably increased desired state may positively influence the perception of the current situation. Depression negatively influences the interpretation of the Calman gap. (shrink)

There is ample evidence that in classical truth table task experiments false antecedents are judged as ?irrelevant?. Instead of interpreting this in support of a suppositional representation of conditionals, Schroyens (2010a, 2010b) attributes it to the induction problem: the impossibility of establishing the truth of a universal claim on the basis of a single case. In the first experiment a truth table task with four options is administered and the correlation with intelligence is inspected. It is observed that ?undetermined? is (...) chosen in one third of the judgements and ?irrelevant? in another third. A positive correlation is revealed between intelligence and the number of ?irrelevant? and ?undetermined? judgements. The data do not exclude that a part of the ?irrelevant? judgements in classical truth table task experiments might be caused by the induction problem. In the second experiment participants are presented with a simplified four-option truth table task and asked for a justification of their judgements. These justifications show the induction problem is not the reason for choosing the ?irrelevant? or ?undetermined? option, which is supportive for a suppositional representation of conditionals.

Physicalists typically believe that neurophysiology has refuted the thesis that non-physical minds can interact with the brain. In this paper, I argue that it is precisely a closer look at the neurophysiology of volitional actions that suggests otherwise. I start with a clarification of how the present inquiry relates to the main argument for physicalism, and how the most common alternative views relate to the findings of my study. I then give a brief overview of the neurophysiological research about volitional (...) actions, finding that there is no research specifically directed at the pertinent question. I proceed by pointing out what it would take for a complete physical explanation of volitional actions to be true: namely a complete physical explanation of the increase in the firing rate of the neurons with which the sequence leading up to volitional actions starts. Since no dedicated research about this question is available, I offer a study of the known mechanisms of neuronal excitation as a substitute, finding that there is no plausible biochemical or physical mechanism that could explain the causal initiation of volitional actions – at least none that upholds energy conservation. But non-conservation is precisely what interactive dualism, in its most plausible version, predicts. Thus, rather than buttressing physicalism, our empirical knowledge of volitional actions points toward interactive dualism. (shrink)

This paper reconsiders semiotic modelling in light of recent scholarship on Charles Peirce, particularly regarding his concept of proposition. Conceived in the vein of Peirce’s phenomenological categories as well as of his taxonomy of signs, semiotic modelling has mostly been thought of as ascending from simple, basic sign types to complex ones. This constitutes the backbone of most currently accepted semiotic modelling theories and entails the further acceptance of an unexamined a priori coherence between complexity of cognition and complexity of (...) signification. Following recent readings of Peirce’s post-1900 semiotic, we engage in a discussion as to what are the limits of this approach. From Stjernfelt’s conception of the dicisign in nature, we derive a perspective that affords understanding the practice of modelling as a reciprocal interplay between decomposition of complexity and recombination into further complexity. This discussion is facilitated by the recent extrapolation of the constructivist concept of scaffolding in biosemiotics research. Cognition, we argue, begins with a fundamental irritation of trying to make sense of a structure that is more complex than what can directly be derived from experience and, in so doing, urges meaning-seeking processes. The yet unknown object is decomposed into more tangible objects and is subsequently reassembled from these more manageable conceptions of the object. In support of our argument, we discuss the notions of semiotic competences and resources in light of such a naturalized account of meaning-making. (shrink)
