The Igbo knowledge system articulated by Amaechi Udefi is insufficient to ensure knowledge progress as opposed to the system found in fallibilism theory. The reason is that there is a level of intellectual openness fallibilism theory guarantees that is not found in Udefi’s thought. This paper aims to do a comparative study of fallibilism theory and Udefi’s account of the Igbo knowledge system. The study also investigates to what extent each knowledge system can ensure knowledge growth and development. The significance (...) of this study is to highlight the importance of knowledge progress in the overall development of society. This paper argues that even though Udefi and Popper were reasoning from different cultural environments, Popper’s falsifiability theory is more open to knowledge progress than Udefi’s Igbo knowledge system. The expository, historical, comparative and evaluative methods were used. (shrink)

The idea of transgender identity is less perceived as a mental illness but as a sexual health condition in many parts of the Western world, while it is seen as an anomaly in most parts of Africa. Transgender identity is a gender expression that differs from the naturally assigned sex. The widely accepted reason behind transgender is unsatisfactory feelings toward assigned sex by the individual. This work sets out to explore transgender identity and family life in Africa. Several works have (...) explored the concept but with less emphasis on family life as it relates to the African setting. Furthermore, this work sets out to demonstrate some implications of transgender identity in an ideal African family. In this work, we shall argue that once transgender identity is normalized in Africa, it will be a threat to family life. The arguments to be used are historical, analytical, descriptive as well as evaluative. (shrink)

Two semantic theories of proper names are explained and assessed. The theories are Burge’s treatment of proper names as complex demonstratives and Larson and Segal’s quasi-descriptivist account of names. The two theories are evaluated for empirical plausibility. Data from deficits, processing models, developmental studies and syntax are all discussed. It is concluded that neither theory is fully confirmed or refuted by the data, but that Larson and Segal’s theory has more empirical plausibility.

This article seeks to contribute to a vision for leadership in business based on a recovery of virtue. The vision for leadership articulated here draws principally on the writings of the classical philosopher Aristotle and of the contemporary philosopher Josef Pieper. Without discounting the ever-increasing complexity of modern business, this essay will attempt to reconstruct Aristotle’s emphasis on virtue and moral character, and argues for the philosopher’s relevance to modern management and corporate leadership. The paper concludes that the message of (...) virtue is a message of hope and attempts to find plain language to articulate its value to those engaged in business or concerned with the formulation of government policy.

We shall introduce in this paper a language whose formulas will be interpreted by games of imperfect information. Such games will be defined in the same way as the games for first-order formulas except that the players do not have complete information of the earlier course of the game. Some simple logical properties of these games will be stated together with the relation of such games of imperfect information to higher-order logic. Finally, a set of applications will be outlined.

Because humans cannot know one another’s minds directly, every form of communication is a solution to the same basic problem: how can privately held information be made publicly accessible through manipulations of the physical environment? Language is by far the best studied response to this challenge. But there are a diversity of non-linguistic strategies for representation with external signs as well, from facial expressions and fog horns to chronological graphs and architectural renderings. The general thesis of this dissertation is that (...) there is an impressively wide spectrum of conventional systems of representation, corresponding to the many ways that the problem of communication can be solved, and that these systems can be described and explained using the tools of contemporary mathematical semantics. As a partial corrective to the countervailing norm, this work concentrates on the class of systems arguably most different from language— those governing the interpretation of pictorial images. Such representations dominate practical communication: witness the proliferation of maps, road signs, newspaper photographs, scientific illustrations, television shows, engineering drawings, and even the fleeting imagery of manual gesture. I argue that systems of depiction and languages embody a parallel technologies of communication. Both are based on semantics: systematic and conventional mappings from signs to representational content. But I also provide evidence that these semantics are profoundly divergent. Whereas the semantics of languages are based on arbitrary associations of signs and denotations, the semantics of systems of depiction are based on rules of geometrical transformation. Drawing on recent research in computer graphics and computational vision, I go on to develop a precise theory of pictorial semantics. This in turn facilitates a detailed comparison of iconic, image-based representation, and symbolic, language-based representation. A consequence of these conclusions is that the traditional, language-centric conception of semantics must be overhauled to allow for a more general semantic theory, one which countenances the wide variety of interpretive mechanisms actually at work in human communication.

This essay argues for a model of pictorial representation which aims to explain the relationship between pictorial content and pictorial accuracy. Focusing on cases where pictures are intended to convey accurate information, the model distinguishes between two fundamental representational relations: on one hand, a picture expresses a content; on the other, it aims at a target scene. Such a picture is accurate when the content it expresses fits the target scene it aims at. In addition, the model follows the traditional (...) division of content into two aspects: singular content specifies the particular individuals which a picture is of, and attributive content specifies the properties and relations which the picture ascribes to those individuals. For a picture to be accurate, both aspects must be matched in the target. I call this the Three-Part Model because it distinguishes between the triad of factors, singular content, attributive content, and target, which together determine pictorial accuracy. Though previous work on depiction has not recognized the distinctive role played by target, I will argue that it is essential in order to make sense of accuracy judgements across a range of central cases.

We give three counterexamples to the folklore claim that in an arbitrary theory, if a complete type p over a set B does not divide over $C\subseteq B$, then no extension of p to a complete type over $\operatorname {acl}(B)$ divides over C. Two of our examples are also the first known theories where all sets are extension bases for nonforking, but forking and dividing differ for complete types (answering a question of Adler). One example is an $\mathrm {NSOP}_1$ theory (...) with a complete type that forks, but does not divide, over a model (answering a question of d’Elbée). Moreover, dividing independence fails to imply M-independence in this example (which refutes another folklore claim). In addition to these counterexamples, we summarize various related properties of dividing that are still true. We also address consequences for previous literature, including an earlier unpublished result about forking and dividing in free amalgamation theories, and some claims about dividing in the theory of generic $K_{m,n}$ -free incidence structures.

The study aims at expanding the idea of knowledge beyond the notion of descriptive knowledge. It examines a pluralism of scientific, philosophical, literary, and aesthetic forms of knowledge. This pluralism is not relativistic but complementary. Different ways of knowing enrich each other thus facilitating a more comprehensive and differentiated conception of the world.".

The European Commission produces the European Core Health Indicators, a database containing different tools used to compare European Union countries and recommend policy changes. The ECHI feeds multiple reports and documents and finds its way into health policies. From this arises the main research question addressed in this paper: How is health in Europe influenced by ECHI data practices? Specifically, we look at how some health issues or populations are prioritized or dismissed, which ultimately shapes the meaning of and knowledge (...) about health in Europe. To do so, we first develop the conceptual framework of “data performativity,” underlining how data practices shape their object/subject. We then explore the politics of evidence behind the ECHI health data that materialize into the absence of some health issues and populations and the hypervisibility of neoliberal health. In the end, we argue, the ECHI serves as a site of individual, collective, and political identity enunciation. (shrink)

Para España y para varios otros países importantes, como Rusia, China, Italia, Portugal, Grecia y México, el período de adolescencia fue el siglo XX, y vino acompañado de grandes crisis políticas y económicas: una gran depresión, un destronamiento, una guerra civil y dos dictaduras, una de ellas, la de Franco, de 36 años. Pero cosas parecidas ocurrieron en los otros países mencionados, mutatis mutandis. El autor de este artículo es de los que piensan que entre los muchos usos de la (...) Historia está el allegar elementos para conjeturar sobre el futuro. Esta era también una de las sugerencias de los editores de Araucaria. La madurez de España comienza casi exactamente con el siglo XXI y el hito escogido es la adopción del euro. A pesar de que esta operación vino coronada por el éxito, la prognosis del autor no es muy optimista, ya que la adolescencia de España no sirvió para resolver varios graves problemas, entre los que destacan el de los nacionalismos periféricos y el de la formación de capital humano.

The use of genomic testing in pregnancy is increasing, giving rise to questions over how the information that is generated should be offered and returned in clinical practice. While these tests provide important information for prenatal decision-making, they can also generate information of uncertain significance. This paper critically examines three models for approaching the disclosure of variants of uncertain significance (VUS), which can arise from forms of genomic testing such as prenatal chromosomal microarray analysis (CMA). Contrary to prevailing arguments, we (...) argue that respect for reproductive autonomy does not justify adopting a model on which an offer to disclose VUS is a routine part of genetic counselling. Instead, we contend that a commitment both to solidarity between healthcare providers and pregnant women and to the acceptance of a novel principle of caution under normative uncertainty means that we should instead adopt a model of VUS disclosure that imposes a strong presumption against offering to disclose VUS. The upshot of this is that it should be standard practice to only offer to disclose VUS when this is requested by the woman undergoing CMA. We defend our position against claims that arise from an alleged right to such information and that a presumption against an offer will lead to inequity. (shrink)

El presente trabajo se propone subrayar la relevancia filosófica del amor acudiendo al desarrollo analítico que del mismo realiza Harry G. Frankfurt. Para ello nos valdremos de la categorización que establece Bennett Helm y encuadraremos la teoría de Frankfurt dentro de una categoría concreta: la del amor como «gran preocupación» [«robust concern»]. Esto nos servirá para atender a la psicología moral de dicho autor y al peso decisivo que el amor juega en la misma; revestido aquel, como afirma Frankfurt, de (...) una autoridad tal que dota de sentido último a nuestro razonamiento práctico. Finalmente, y expuesta la relevancia del amor dentro de todo este proceso, se procederá a discutir de la mano de Jonathan Lear si el amor posee la autoridad que Frankfurt le asigna. (shrink)

Achille Mbembe’s book Critique of Black Reason has attracted scholarly interest and commentaries. In a conversation that took place between David Theo Goldberg and Mbembe, both men discuss some of the themes that are raised in the book. This paper examines that conversation and focuses on the idea of the archive and how the dehumanisation, damage, destruction and death that racism has visited on many black people can be resurrected, dusted down and repaired. I have used Mbembe’s idea of blackness (...) as a way into the archive to retrieve and retell a particular story and, in doing so, to repair the damage to the life of an African American man, as only writing can do. I revive the humanity and dignity of that life against the brutal racism that ultimately claimed it. This is a requiem for Mr Wilson. (shrink)

Achille Mbembe’s latest book addresses some of the existential concerns of the modern age and the power structures that have shaped them. Modernity’s allure has created a false belief in the idea of progress while concealing a destructive streak in human activities. He warns that there is trouble ahead unless humans chart a different course. But is this the lamentation of a Jeremiad or a timely intervention in the current state of the world?

This paper offers a new version of a historically influential, yet today unpopular, neglected, and on the whole insufficiently developed argument for socialism: socialism makes it possible for people to really act together. This idea of socialist action, combining the claims that there is a particularly valuable form of joint action and that socialism is about making such action possible, played an important role in the history of the labor movement, going back to the early Marx and running through various (...) strands of socialist thought. I shall argue that socialist action should be seen as central to the socialist project, its critique of capitalism, and the institutional alternatives envisaged by it. (shrink)

In this paper we show that first-order languages extended with partially ordered connectives and partially ordered quantifiers define, under a certain interpretation, their own truth-predicate. The interpretation in question is in terms of games of imperfect information. This result is compared with those of Kripke and Feferman.

While much has been written on phronesis, there is a dearth of empirical work on the how the concept can be developed and implemented in practice, particularly in an educational setting. To address this problem, characteristics of phronesis were identified through a review of current literature and an examination of related themes from a special issue of the Philosophy of Management Journal on the philosophy of innovation. The implementation of the concept was investigated using an illustrative study of ongoing work (...) aimed at embedding phronesis in an innovation educational module. The study will contribute to the nascent debate by providing evidence of embedding Aristotle’s phronesis in the curriculum of future managers, in this case Engineering and Business students, working in cross-functional teams. A schema is proposed, based on concepts distilled from the literature and the illustrative study, to examine whether an educational project cultivates phronesis among the students. (shrink)

Xenophon’s anecdote concerning the exchange of clothes between a big boy and a little boy in Cyropaedia offers a valuable framework for understanding his conception of justice and the problematics of administering it. Interpreters have erred by assuming that Cyrus’ teacher, as well as Socrates in Memorabilia, simply identifies the just with the lawful. Rather than identifying the two, both characters argue that the law is just; but they differ widely in their explanations of what makes the law just. For (...) Cyrus’ teacher, the obligation to observe the law rests on a universal pre-legal ban on violence; for Socrates statutory law is to be obeyed for utilitarian reasons. Socrates’ view thus justifies both the teacher’s insistence that Cyrus obey the law—since the law is of benefit to the community—and also Cyrus’ decision to violate the law to achieve a just and beneficial redistribution. But it offers no justification for a universal ban on violence. In conformity with the Socratic principle, Cyrus avoids violence as far as possible, but only for the prudential reasons expressed by his mother. Once he acquires the power to coerce, Cyrus uses it to enforce the principle of proportional equality and meritorious redistribution he had approved in his judgment of the actions of the big boy.

As it has historically been the case with many pandemics, the Covid-19 experience will induce many philosophers to reconsider the value of medical practice. This should be a good opportunity to critically scrutinize the way medical research and medical interventions are carried out. For much of its history, medicine has been very inefficient. But, even in its contemporary forms, a review of common protocols in medical research and medical interventions reveal many shortcomings, especially related to methodological flaws, and more importantly, (...) conflicts of interests due to profit incentives. In the face of these problems, we propose a program of “gentle medicine”. This term, originally formulated by philosopher Jacob Stegenga, describes a form of medicine in which physicians intervene less than they currently do. As part of this general program, we advance a series of reform recommendations that could be enacted both by medical staff in their everyday practice, but also by public health officials and policymakers.

It is argued that alcoholism, and substance addiction generally, is a disease. It is not of its nature chronic or progressive, although it is in serious cases. It is better viewed as a psychological disease than a neurological one. It is argued that each time an alcoholic takes a drink, this is the result of choice; however, in cases of serious affliction, such choices are compulsive and may be called 'involuntary' in that they are made against the subject's will, motivated (...) by an overwhelmingly powerful desire that he wishes he did not have and not to act on. Alternative accounts in terms social learning theory and behavioral economics are critiqued. The conception of alcoholism as a tripartite disease composed of a 'physical allergy,' a mental obsession, and a 'spiritual malady' is defended from a contemporary scientific point of view. (shrink)

Bien que les théories de la conspiration médicale existent depuis au moins deux siècles, elles sont devenues plus populaires et plus persistantes ces derniers temps. C’est devenu un problème urgent pour la pratique médicale, car ces croyances irrationnelles peuvent constituer un obstacle à des procédures médicales importantes, telles que la vaccination. Si les spécialistes s’accordent à dire que le problème des théories de la conspiration médicale doit être abordé, il n’y a pas de consensus sur la meilleure approche à adopter. (...) Dans cet article, nous évaluons quelques stratégies. Malgré les risques encourus, il est important de s’intéresser aux théories de la conspiration médicale et de les réfuter. Toutefois, la proposition de le faire dans le cadre d’une “infiltration cognitive” est trop risquée. Les médias ont un rôle majeur à jouer dans la réfutation des théories de la conspiration médicale, mais il est important que les journalistes ne politisent pas cette tâche. Deux autres stratégies à long terme sont également nécessaires: la stimulation de la pensée critique dans l’enseignement et l’autonomisation des groupes traditionnellement marginalisés. (shrink)

Independence‐Friendly logic introduced by Hintikka and Sandu studies patterns of dependence and independence of quantifiers which exceed those found in ordinary first‐order logic. The present survey focuses on the game‐theoretical interpretation of IF‐logic, including connections to solution concepts in classical game theory, but we shall also present its compositional interpretation together with its connections to notions of dependence and dependence between terms.

For n≥3, define Tn to be the theory of the generic Kn-free graph, where Kn is the complete graph on n vertices. We prove a graph-theoretic characterization of dividing in Tn and use it to show that forking and dividing are the same for complete types. We then give an example of a forking and nondividing formula. Altogether, Tn provides a counterexample to a question of Chernikov and Kaplan.

In his article The Foundations of Mathematics (1925) Ramsey was concerned with the nature of the statements of 'pure mathematics' and the way these statements differ from those in empirical sciences. He thought that the answer given to these questions by Hilbert and the formalist school according to which mathematical statements are meaningless formulas, is unsatisfactory for several reasons, which will not be discussed here. He also expressed serious doubts about the intuitionist program developed by Brouwer and Weyl. It is (...) the logicist school of Frege, Russell and Whitehead, which attempted to reduce mathematics to few logical concepts, that came closest to Ramsey’s views, although he was not completely satisfied with it, either.

No decorrer do debate sobre o realismo científico, alguns antirrealistas, tal como Leo Tolstói e Larry Laudan, criaram um desafio cético para os realistas, questionando, com base na história da ciência, a crença realista de continuidade entre as teorias do passado, atuais e futuras. Stathis Psillos ofereceu uma réplica que ficou conhecida como realismo seletivo ou divide et impera, alegando que, através de um minucioso exame, podemos encontrar elementos teóricos de continuidade entre teorias passadas e atuais, assegurando, por analogia, que (...) as teorias futuras também possuirão elementos de continuidade com as atuais. A estratégia de Psillos, se bem empregada, pode evidenciar que a leitura realista de história da ciência também possui suas virtudes e deve ser considerada. Todavia, no presente artigo, argumentamos que mesmo que o realismo seletivo de Psillos se mostre aplicável, ele deve ser considerado como uma crítica a concepções descontinuístas em história da ciência e não necessariamente ao antirrealismo científico em geral, posto que o empirismo construtivo de Bas van Fraassen, por exemplo, admite a continuidade teórica na ciência.

O presente artigo objetiva realizar um estudo de caso que aplica o modelo de inferência da melhor explicação (inference to the best explanation, IBE) de Peter Lipton ao episódio histórico da construção do modelo de dupla-hélice do DNA, no século XX. Procura avaliar a eficiência de tal modelo quando confrontado com a história da ciência e em que medida é capaz de rivalizar com ou superar outros modelos de explicação já consolidados na literatura de filosofia da ciência, tais como os (...) modelos nomológico-dedutivo e indutivo-estatístico de Carl Hempel, o modelo de relevância estatística de Wesley Salmon, ou, ainda, o modelo pragmático de explicação de Bas van Fraassen. Por fim, a conclusão apresentada é que o modelo de inferência da melhor explicação se mostra mais eficaz para ilustrar esse episódio da história da genética do que as outras propostas filosóficas analisadas.
