El reto de la sofística obligó a Platón a afirmar el juego recíproco de Nomos y Logos, de ley y medida, para poder sostener debidamente la ilustración de la comunidad política en su intercambio retórico constante. La sofística demostró que el Nomos absoluto no existe y que son los hombres quienes tienen que forjarlo. Sobre la racionalidad de la retórica se erigió la sofística, cuyo objetivo fue ganar ilustración para las decisiones públicas. Retórica y sofística ven correctamente que la acción (...) política razonable está mediatizada por el lenguaje, pero caen en un error al asumir el Logos como mero instrumento o estrategia individuales, pues ello hace estallar la comunidad política. El saber como dialéctica es una respuesta de Platón a la lucha de opiniones que practican los sofistas. El saber es saber en la opinión, reflexión inmanente a la praxis, siempre abierta a la corrección. (shrink)

Plato’s Meno offers important elements of his educational theory. This article begins with a brief introduction to this work, and then presents an analysis of several ideas that appear throughout it, with a special emphasis on those dealing directly or indirectly with the central theme of education and human communication. The article concludes with a summary of the work’s main arguments.

Retomo, en este artículo, la conocida distinción platónica entre doxa y epistêmê, hecha principalmente en el Menón y la República. Pero subrayo con énfasis particular la diferencia de criterios, de un diálogo a otro. Mientras que en el primero predomina el criterio lógico de la estabilidad de epistêmê y la inestabilidad dóxa, debida respectivamente a la concatenación (desmós) y la falta de concatenación de sus elementos, el segundo enfatiza el criterio ontológico de los objetos:la misma cosa no puede ser aprehendida (...) por la ciencia y la opinión, pues la primera concierne al ser absoluto, identificado con las Formas platónicas, y la segunda a algo que es intermedio entre el ser absoluto y el no-ser absoluto. Después de objetar que Platón no logra demostrar su división tripartita de la realidad, sostengo que la diferencia de criterios aquí analizada se debe a la ausencia de la Teoría Platónica de las Formas en el Menón. Palabras clave: Platón; Doxa; Epistêmê; Distinción; CriteriosI return in this paper to the well-known Platonic distinction between doxa and episteme, drawn mainly in Meno and Republic. However, I stress now the difference in criteria from one dialogue to the other. While in the first prevails the logical criterion of stability of epistêmê and unstableness of dóxa, owing respectively to the concatenation (desmós) and the lack of concatenation of their elements, the second emphasizes the ontological criterion of objects: the same thing cannot be apprehended by science and opinion, for the former concerns to absolute being, identified with Platonic Ideas, while the latter to something which is halfway between absolute being and absolute not-being. After objecting that Plato fails to demonstrate his tripartite division of reality, I claim that the difference of criteria hereby analyzed is due to the absence of Plato’s Theory of Ideas in Meno. KeyWords: Plato; Doxa; Epistêmê; Distinction; Criteria. (shrink)

This work articulates two thesis: one Socratic and one Platonic; and displays how the first one is heir of the second. The Socratic one is called the principle of priority of definition; the Platonic one is the Recollection theory. The articulation between both theses is possible due to the Meno’s paradox, which makes a criticism on the first thesis, but it is solved with the second one. The consequence of this articulation is a new interpretation of the Recollection theory, as (...) a theory of knowledge acquisition that depends, mainly, on a distinction between knowledge and true opinion. To conclude, a new interpretation of the knowledge/true opinion distinction is displayed –not in the traditional fashion, evaluating the propositions one by one, and in an atomic way–, but as big blocks or chains of propositions shaping knowledge through explanatory reasoning (aitías logismós).

El presente artículo argumenta que hay un desarrollo en la postura de Platón frente a la geometría. A partir del primer contacto con la geometría, Platón se sintió atraído hacia la geometría por sus sorprendentes resultados. Por tal motivo, en un primer momento, Platón presenta en el Menón y en el Teeteto a la geometría como una ciencia ejemplar y le pide a los interlocutores que imiten sus procesos. En un segundo momento, Platón en la República incluye a la geometría (...) dentro de la filosofía, hace que el método de la geometría fundamente a su máxima ciencia dialéctica, incluye a los entes geométricos dentro del edificio ontológico, y a la ciencia geométrica dentro de las disciplinas que el rey-filosofo debe estudiar para ascender a las ideas. En un tercer momento, en el Timeo, la geometría es la ciencia básica que utiliza el Demiurgo para componer al universo. (shrink)

Robustness arguments hold that hypotheses are more likely to be true when they are confirmed by diverse kinds of evidence. Robustness arguments require the confirming evidence to be independent. We identify two kinds of independence appealed to in robustness arguments: ontic independence —when the multiple lines of evidence depend on different materials, assumptions, or theories—and probabilistic independence. Many assume that OI is sufficient for a robustness argument to be warranted. However, we argue that, as typically construed, OI is not a (...) sufficient independence condition for warranting robustness arguments. We show that OI evidence can collectively confirm a hypothesis to a lower degree than individual lines of evidence, contrary to the standard assumption undergirding usual robustness arguments. We employ Bayesian networks to represent the ideal empirical scenario for a robustness argument and a variety of ways in which empirical scenarios can fall short of this ideal. (shrink)

The value-free ideal in science has been criticised as both unattainable and undesirable. We argue that it can be defended as a practical principle guiding scientific research even if the unattainability and undesirability of a value-free end-state are granted. If a goal is unattainable, then one can separate the desirability of accomplishing the goal from the desirability of pursuing it. We articulate a novel value-free ideal, which holds that scientists should act as if science should be value-free, and we argue (...) that even if a purely value-free science is undesirable, this value-free ideal is desirable to pursue. (shrink)

The value-free ideal for science holds that values should not influence the core features of scientific reasoning. We defend the difference-to-inference model of value-permeation, which holds that value-permeation in science is problematic when values make a difference to the inferences made about a hypothesis. This view of value-permeation is superior to existing views, and it suggests a corresponding maxim—namely, that scientists should strive to eliminate differences to inference. This maxim is the basis of a novel value-free ideal for science. -/- (...) . (shrink)

This study aimed to identify the learning and business incubation processes and their impact on developing the performance of business incubators in Gaza Strip, and the study relied on the descriptive analytical approach, and the study population consisted of all employees working in business incubators in Gaza Strip in addition to experts and consultants in incubators where their total number reached (62) individuals, and the researchers used the questionnaire as a main tool to collect data through the comprehensive survey method, (...) where (55) questionnaires were retrieved with a recovery rate of (88.7%). The results of the study showed that there is a high approval of the variables of the study, where the dimension of incubation operations came with a relative weight (84.89%), followed by the learning dimension which got a relative weight (82.50%), while the performance level of the incubators got a relative weight (80.12%) and as the study results showed There is a positive relationship statistically between the two dimensions of learning and business incubation processes and performance development in business incubators, and the linear regression analysis model showed that the main effect in improving the performance of business incubators is "after business incubation operations" while it showed weak effect after learning. The study came out with several recommendations, the most important of which is that business incubators seek to reinforce the learning process and incubation processes for business, and the need to periodically evaluate their performance, and that a more effective mechanism be designed to follow up with companies after the end of the incubation period and monitor the progress of these companies.

For Knox, ‘spacetime’ is to be defined functionally, as that which picks out a structure of local inertial frames. Assuming that Knox is motivated to construct this functional definition of spacetime on the grounds that it appears to identify that structure which plays theoperationalrole of spacetime—i.e., that structure which is actually surveyed by physical rods and clocks built from matter fields—we identify in this paper important limitations of her approach: these limitations are based upon the fact that there is a (...) gap between inertial frame structure and that which is operationally significant in the above sense. We present five concrete cases in which these two notions come apart, before considering various ways in which Knox’s spacetime functionalism might be amended in light of these issues. (shrink)

Brown and Pooley’s ‘dynamical approach’ to physical theories asserts, in opposition to the orthodox position on physical geometry, that facts about physical geometry are grounded in, or explained by, facts about dynamical fields, not the other way round. John Norton has claimed that the proponent of the dynamical approach is illicitly committed to spatiotemporal presumptions in ‘constructing’ space-time from facts about dynamical symmetries. In this article, I present an abstract, algebraic formulation of field theories and demonstrate that the proponent of (...) the dynamical approach is not committed, in special relativity, to the illicit presumptions to which Norton refers.

Este texto pretende-se um ensaio sobre a questão do Espiritual na teoria pictórica de Kandinsky. Nele busco evidenciar a idéia de que as concepções do pintor russo, em grande parte construída em consonância com o pensamento esotérico do fim do século XIX, aproximam-se bastante de um tipo de cosmologia mágica, que abriga uma perspectiva análoga àquela das categorias do pensamento mágico segundo Marcel Mauss. No centro desta cosmologia encontra-se a arte, síntese do Espiritual, cuja noção central é a de gênio (...) que creio ser herdada em grande medida de Kant. (shrink)

Recent work in the physics literature demonstrates that, in particular classes of rotating spacetimes, physical light rays in general do not traverse null geodesics. Having presented this result, we discuss its philosophical significance, both for the clock hypothesis, and for the operational meaning of the metric field.

If we cannot directly empirically test the claims of particular scientific theory, then it would be nice to have some other criteria with which to assess its viability. In his 2013 book, String Theory and the Scientific Method, Richard Dawid aims to develop such criteria, with an eye to vindicating research programs in disciplines where direct empirical data is scant or non-existent. In an accompanying paper, Dawid, Hartmann and Sprenger formalise Dawid’s so-called ‘No Alternatives Argument’ using a generalised Bayesian framework, (...) as a first step towards formalising Dawid’s entire re- search programme. In this paper, I argue that the formalisation of the NAA cannot play the central role in Dawid’s programme as intended. This is based on the observation that not all confirmation is non-negligible confirmation. For Dawid’s programme to be useful, it must demonstrate the viability not just of non-empirical theory confirmation, but of non-negligible non-empirical theory confirmation. I argue that Dawid et al.’s appeal to Bayesian confirmation theory to formalise his NAA cannot guarantee non-negligible confirmation. As a result, I conclude that if Dawid’s overall project is to succeed, it must do so without the NAA formalised in this way. (shrink)

In psychiatry, pharmacological research has played a crucial role in the formulation, revision, and refinement of neurobiological theories of psychopathology. Besides being utilized as potential treatments for various mental disorders, pharmacological drugs play an important epistemic role as experimental instruments that help scientists uncover the neurobiological underpinnings of mental disorders (Tsou, 2012). Interventions with psychiatric patients using pharmacological drugs provide researchers with information about the neurobiological causes of mental disorders that cannot be obtained in other ways. This important source of (...) evidence for the biological causes of mental disorder is often overlooked in philosophical analyses of psychiatry, especially in skeptical analyses that debase the biological aspects of psychopathology (e.g., Szasz, 1960; Scheff, 1963; Laing, 1967). In discussing pharmacological interventions as a form of evidence for the physical basis of mental disorders, this paper aims to clarify the nature, reliability, and limitations of this evidence. In addition, it illustrates the central role that pharmacological findings in applied clinical contexts play in the acquisition of neurobiological knowledge in research contexts. (shrink)

Phase transitions are an important instance of putatively emergent behavior. Unlike many things claimed emergent by philosophers, the alleged emergence of phase transitions stems from both philosophical and scientific arguments. Here we focus on the case for emergence built from physics, in particular, arguments based upon the infinite idealization invoked in the statistical mechanical treatment of phase transitions. After teasing apart several challenges, we defend the idea that phase transitions are best thought of as conceptually novel, but not ontologically or (...) explanatorily irreducible to finite physics; indeed, by looking at ongoing work on “smooth phase transitions” we even suggest that they’re not even conceptually novel. In the case of renormalization group theory, consideration of infinite systems and their singular behavior provides a central theoretical tool, but this is compatible with an explanatory reduction. Phase transitions may be “emergent” in some sense of this protean term, but not in a sense that is incompatible with the reductionist project broadly construed. (shrink)

Jonathan Y. Tsou examines and defends positions on central issues in philosophy of psychiatry. The positions defended assume a naturalistic and realist perspective and are framed against skeptical perspectives on biological psychiatry. Issues addressed include the reality of mental disorders; mechanistic and disease explanations of abnormal behavior; definitions of mental disorder; natural and artificial kinds in psychiatry; biological essentialism and the projectability of psychiatric categories; looping effects and the stability of mental disorders; psychiatric classification; and the validity of the DSM's (...) diagnostic categories. The main argument defended by Tsou is that genuine mental disorders are biological kinds with harmful effects. This argument opposes the dogma that mental disorders are necessarily diseases that result from biological dysfunction. Tsou contends that the broader ideal of biological kinds offers a more promising and empirically ascertainable naturalistic standard for assessing the reality of mental disorders and the validity of psychiatric categories.

Purpose. The dynamics and pace of social and economic transformations that are characteristic of modern society, lead to an increase in tension and the destruction of habitual stereotypes – ideals, values, norms, patterns of behaviour that unite people. These moments encourage us to rethink the understanding of "security" essence, in particular, psychological, which emphasizes the urgency of its study in the philosophical and sociocultural coordinates. Theoretical basis of the research is based on the philosophical methodology of K. Jaspers, E. Fromm (...) and the A. Maslow’s psychological approach to understanding of a person. Originality. Psychological security is considered at different levels: first and foremost, society is a characteristic of social security, that is an analysis of how today’s social technologies, social changes affect the quality of life of the country’s population; secondly, the social environment – the family, the immediate environment, reference groups, training teams; thirdly, a person is an experience of his own security-insecurity, when it is possible to talk about the manifestations of psychological violence, when certain behavioral acts contribute to the violation of the security of the other or to self-destruction. It is found out that the knowledge of psychological security is closely connected with the socio-historical conditions of being, with the level of development of material and spiritual culture, with the interests and values prevailing in society, which determines its ontological, epistemological and axiological features. The presented issue is considered in the correlation of psychological security with types of scientific rationality – classical, nonclassical and post-nonclassical approaches, within the framework of which various perspectives, aspects, forms and types of psychological security are studied. Conclusions. The concept of security requires a systematic description of its manifestations, types, levels, concepts: security as the absence of dangers ; security as a certain activity to ensure or to prevent any threats or dangers ; security as a conscious necessity, the value of the individual. The study systematizes various ideas about psychological security in accordance with the logic of scientific knowledge: in the mainstream of classical, non-classical and post-nonclassical approaches.

Noncommutative geometries generalize standard smooth geometries, parametrizing the noncommutativity of dimensions with a fundamental quantity with the dimensions of area. The question arises then of whether the concept of a region smaller than the scale—and ultimately the concept of a point—makes sense in such a theory. We argue that it does not, in two interrelated ways. In the context of Connes’ spectral triple approach, we show that arbitrarily small regions are not definable in the formal sense. While in the scalar (...) field Moyal–Weyl approach, we show that they cannot be given an operational definition. We conclude that points do not exist in such geometries. We therefore investigate (a) the metaphysics of such a geometry, and (b) how the appearance of smooth manifold might be recovered as an approximation to a fundamental noncommutative geometry.

Family involvement in healthcare decision-making for competent patients occurs to varying degrees in many communities around the world. There are different attitudes about who should make treatment decisions, how and why. Legal and professional ethics codes in most jurisdictions reflect and support the idea that competent patients should be enabled to make their own treatment decisions, even if others, including their healthcare professionals, disagree with them. This way of thinking contrasts with some cultural norms that put more emphasis on the (...) family as a decision-making entity, in some circumstances to the exclusion of a competent patient. Possible tensions may arise between various combinations of patient, family members and healthcare professionals, and healthcare professionals must tread a careful path in navigating family involvement in the decision-making process. These tensions may be about differences of opinion about which treatment option is best and/or on who should have a say or influence in the decision-making process. While some relevant cultural, legal and policy considerations vary from community to community, there are ethical issues that healthcare professionals need to grapple with in balancing the laws and professional codes on decision-making and the ethical principle of respecting patients and their autonomy. This paper will highlight and propose that a partial resolution to these issues may lie in relational understandings of autonomy, which in principle justify interventions by healthcare professionals and family that support patients in decision-making.

Supersymmetry (SUSY) is a proposed symmetry between bosons and fermions. The structure of the space of SUSY generators is such that the distinction between internal and spacetime symmetries is blurred. As a result, there are two viable candidates for the correct spacetime setting for a flat supersymmetric field theory---Minkowski spacetime and superspace. an extension of four- dimensional Minkowski spacetime to include (at least) four new dimensions, coordinatised by mathematical objects known as supernumbers. These objects are, in one significant way, quite (...) different from real or complex number---some of them have the property that their order of multiplication makes a difference; in mathematical terms, they are said to have nontrivial commutation properties. This paper argues for two theses: first, that one standard set of arguments, related to universality of symmetry behaviour, that motivate a particular choice of spacetime structure in familiar spacetime theories motivates the choice of superspace as the appropriate spacetime for SUSY field theories. And second, that the metaphysical utility of the concept of spacetime requires more than just the satisfaction of this universality condition; in supersymmetric theories, the spacetime concept is not as useful as in special relativity.

In a recent article, Halvorson and Manchak (Br J Philos Sci, Forthcoming) claim that there is no basis for the Hole Argument, because (in a certain sense) hole isometries are unique. This raises two important questions: (a) does their argument succeed?; (b) how does this formalist response to the Hole Argument relate to other recent responses to the Hole Argument in the same tradition—in particular, that of Weatherall (Br J Philos Sci 69(2):329–350, 2018)? In this article, _ad_ (a), we argue (...) that Halvorson and Manchak’s claim does not go through; _ad_ (b), we argue that although one _prima facie_ plausible reading would see Halvorson and Manchak as filling an important hole (no pun intended) in Weatherall’s argument, in fact this reading is implausible; there is no need to supplement Weatherall’s work with Halvorson and Manchak’s results.

Therapeutic privilege is a defence that may be available to doctors who fail to disclose to the patient relevant information when seeking informed consent for treatment if they have a reasonable belief that providing that information would likely cause the patient concerned serious physical or mental harm. In a landmark judgement, the Singapore Court of Appeal introduced a novel interpretation of TP, identifying circumstances in which it might be used with patients who did not strictly lack capacity but might be (...) inclined to refuse recommended treatments. In this paper, we explore the conceptual and practical challenges of this novel interpretation of TP. We propose that more emphasis should be placed on forms of shared and supported decision-making that foster the autonomy of patients with compromised mental capacity while being mindful of the need to safeguard their well-being. The kind of privilege that doctors might need to invoke is one of time and supportive expertise to ensure a flexible, responsive approach calibrated to the individual patients’ needs. The provision of such service would extinguish the need for the novel TP proposed by the Singapore Court of Appeal. (shrink)

This article tracks the journeys made by the term ‘gender’ in India. From its beginnings in the 1970s as a feminist contribution to public discourse, destabilizing the biological category of ‘sex’, we find that gender has taken two distinct forms since the 1990s. On the one hand, gender as an analytical category is being used to challenge the notion of ‘woman’ as the subject of feminist politics. This challenge comes from the politics of caste and sexuality. On the other hand, (...) gender is mobilized by the state to perform a role in discourses of development, to achieve exactly the opposite effect; that is, gender becomes a synonym for ‘women’. Thus, the first trend threatens to dissolve, and the second to domesticate, the subject of feminist politics. This article explores the implications of both journeys in terms of a feminist horizon.

The study aims to address the existing research gap through a thematic comparison between the aesthetics of Kant and Abhinavagupta. This paper explores Kant’s notion of aesthetic judgment based on disinterestedness with Abhinavagupta’s analysis of sādhāraṇīkaraṇa. We argue that the notions of “disinterested judgment” in Kant and sādhāraṇīkaraṇa in Abhinavagupta points towards the impersonal nature of aesthetic delight which makes the universality of aesthetic experience possible. Hence, aesthetics in both Kant and Abhinavgupta are not the personal and subjective experience but (...) a kind of universality based on the ability to experience the impersonal joy. However, the notion of aesthetic delight in Kant is confined to the agreeable mental states only while in Abhinavgupta the notion of rasa includes both positive as well as the negative mental states like fear, disgust, etc. In this regard, the paper will also analyze the affinity between notion of sensus communius in Kant and sahṛdaya in Abhinavagupta which highlights the importance of aesthetic community and the impersonal nature of aesthetic delight.

Objective To document the legal guardian-related barriers to consent procurement, and their stated reasons for non-participation in a paediatric critical care research study.Study design A multicentre, prospective, cohort study.Participants Legal guardians of children who participated in a multicentre study on adrenal insufficiency in paediatric critical illness. Data were collected on all consent encounters in the main study.Methods Screening data, reasons for consent not being obtained, paediatric risk of mortality scores and age were collected on all 1707 patients eligible for participation (...) in the Adrenal Insufficiency Study.Results The main barriers to approaching legal guardians for consent were lack of availability of the legal guardians and language barriers . Legal guardians of 917 patients were approached with an overall consent rate of 42% . 81% of the 528 legal guardians who declined consent provided an unsolicited reason for refusal. The three most commonly stated reasons were: being overwhelmed , not wanting anything else done to their child and not wanting an additional medication . In addition, 14.2% cited research-related concerns as the reason for their non-participation.Conclusions Barriers to consent procurement in a non-therapeutic paediatric critical care study appear to occur at many levels with lack of availability of legal guardians, and legal guardians feeling overwhelmed, being the most commonly recorded reasons. Further research into the impact of these findings on the validity and generalisability of the results of such studies is necessary prior to the development and study of future consent models.
