My job has been made easier tonight, given that Larry Hickman has already done most of the ‘heavy lifting’ for me. I think his paper is an excellent and convincing intervention into this debate, and one of the problems for me in constructing my talk has been that our discussions have forced me to rethink what I wanted to say. Given my Continental biases, I had expected to come out on Rorty’s side; in writing this paper, however, things have become (...) more complicated. So let me here thank Larry for both at once making my job tonight easier, and much to my chagrin, surprisingly difficult. What I want to suggest, in contrast to what you’ve just heard, is that the neopragmatism of Richard Rorty is not wholly inconsistent with Dewey’s pragmatism – or, at least, with a ‘thin’ version of Deweyian pragmatism. As we shall see, while the differences between Dewey and Rorty on the status of metaphysics are in all probability irreconcilable, Rorty’s reclamation of a ‘thin’ Dewey can be read as consistent with at least the spirit of Dewey’s work. I will try to make the stronger case that this reconciliation is possible according to the letter of Dewey’s philosophy as well, and the interrelated issues of method and social hope will serve as the avenues for this investigation. Given my audience, I imagine that what I’m about to say will be fodder for some interesting conversation, and so, in the spirit of Rorty’s thought, let me get on with my paper. (shrink)

Minęło już ponad trzydzieści lat od publikacji artykułu Hansa Slugi na temat niemieckiej filozofii w czasach narodowego socjalizmu. Tymczasem w Polsce artykuł ten został zupełnie zignorowany. Przytaczam najważniejsze ustalenia Slugi, ale dokonuję także własnej analizy filozoficznych manipulacji, których Nicolai Hartmann dopuścił się m. in. na pojęciu imperatywu kategorycznego. Pseudo-racjonalny charakter tych nadużyć otworzył drogę etyce, która pomogła wdrażać i usprawiedliwiać zbrodnicze poczynania nazistowskiego reżimu. Tym kontrowersyjnym wątkom powinniśmy się przyjrzeć na nowo, ponieważ mogą one stanowić fałszywe uzasadnienie dla demonów (...) przeszłości nękających naszą współczesność. (shrink)

It is a widespread intuition that the coherence of independent reports provides a powerful reason to believe that the reports are true. Formal results by Huemer, M. 1997. “Probability and Coherence Justification.” Southern Journal of Philosophy 35: 463–72, Olsson, E. 2002. “What is the Problem of Coherence and Truth?” Journal of Philosophy XCIX : 246–72, Olsson, E. 2005. Against Coherence: Truth, Probability, and Justification. Oxford University Press., Bovens, L., and S. Hartmann. 2003. Bayesian Epistemology. Oxford University Press, prove that, (...) under certain conditions, coherence cannot increase the probability of the target claim. These formal results, known as ‘the impossibility theorems’ have been widely discussed in the literature. They are taken to have significant epistemic upshot. In particular, they are taken to show that reports must first individually confirm the target claim before the coherence of multiple reports offers any positive confirmation. In this paper, I dispute this epistemic interpretation. The impossibility theorems are consistent with the idea that the coherence of independent reports provides a powerful reason to believe that the reports are true even if the reports do not individually confirm prior to coherence. Once we see that the formal discoveries do not have this implication, we can recover a model of coherence justification consistent with Bayesianism and these results. This paper, thus, seeks to turn the tide of the negative findings for coherence reasoning by defending coherence as a unique source of confirmation. (shrink)

Causal Modeling Semantics (CMS, e.g., Galles and Pearl 1998; Pearl 2000; Halpern 2000) is a powerful framework for evaluating counterfactuals whose antecedent is a conjunction of atomic formulas. We extend CMS to an evaluation of the probability of counterfactuals with disjunctive antecedents, and more generally, to counterfactuals whose antecedent is an arbitrary Boolean combination of atomic formulas. Our main idea is to assign a probability to a counterfactual (A ∨ B) > C at a causal model M as a weighted (...) average of the probability of C in those submodels that truthmake A∨ B (Briggs 2012; Fine 2016, 2017). The weights of the submodels are given by the inverse distance to the original model M, based on a distance metric proposed by Eva, Stern, and Hartmann (2019). Apart from solving a major problem in the epistemology of counterfactuals, our paper shows how work in semantics, causal inference and formal epistemology can be fruitfully combined. (shrink)

The article deals with the anthropological views of M. Olesnytskyі, a professor at the Kyiv Theological Academy (КТА), whose creative work has not yet been properly studied. It reveals the connection of his anthropological ideas with moral theology and ethical doctrine, which he had taught for a long time in the KTA. Anthropological implications of the moral formation of a human person are also paid attention to, in particular, the dependence of the moral character on anthropological factors. In this context, (...) the writing considers Olesnytskyі’s views on the peculiarities of a person’s body-build. The Kyiv scholar focused on the principles of human corporeality based on natural conditions. In particular, Olesnytskyі stressed that it was the earth’s conditions that formed the bodily nature of man. The article also explores those religious ideas that influenced the anthropological views of the Kyiv scholar, which is quite understandable in view of his Christian outlook. Olenytskyі demonstrates the possibility of effective application of contemporary philosophical studies to the theological and anthropological analysis of man as an individual. In this sense, the conceptual connections of the anthropological views of the Kyiv scholar with the ones of the influential contemporary European philosophers and anthropologists, such as А. Schopenhauer, R. H. Lotze, F. Schleiermacher, E. von Hartmann, and others, become clearly evident. The article emphasizes the significance of the concept of the unconscious for the moral anthropological doctrine of Olesnytskyі; it also argues for the connection of this concept to the leading European doctrines of the unconscious, which were elaborated in philosophy and psychology in the second half of the 19 th century.

Antes de entrar cuidadosamente no estudo de cada filósofo, em suas respectivas ordens cronológicas, é necessário dar um panorama geral sobre eles, permitindo, de relance, a localização deles em tempos históricos e a associação de seus nomes com sua teoria ou tema central. l. OS FILÓSOFOS PRÉ-SOCRÁTICOS - No sétimo século antes de Jesus Cristo, nasce o primeiro filósofo grego: Tales de Mileto2 . Ele e os seguintes filósofos jônicos (Anaximandro: Ἀναξίμανδρος: 3 610-546 a.C.) e Anaxímenes: (Άναξιμένης: 586-524 a.C.) tentaram (...) expressar/elucidar o que é a arché, ou constitutivo fundamental do Universo. 4 Também sobressaem as teorias de Pitágoras (Ὁ Πυθαγόρας: 570 a.C.- 495 a.C.), completas de misticismo e Matemática; a de Heráclito (Ἡράκλειτος ὁ Ἐφέσιος: 540-470 a.C.), o filósofo do devir e o de seu oponente, Parmênides (Παρμενίδης: 530-460 a.C.), que elucida a primeira teoria do ser, e para qual é alcunhado como o iniciador da Metafísica. Anaxágoras (Ἀναξαγόρας: 500 a.C.- 428 a.C.) esboça uma teoria sobre o Nous, o espírito divino. Por outro lado, Demócrito (Δημόκριτος: Grécia: 460-370 a.C.) e Empédocles (Ἐμπεδοκλῆς: 490 a.C.-430 a.C.) insistem no materialismo. Em contrapartida, os sofistas (Parmênides, Cálicles (Καλλικλῆς: personagem platônico cuja existência é duvidosa) e Górgias (Γοργίας: 485 a.C.-380 a.C.)) gozam das suas aptidões à dialética, e colocam o relativismo como uma posição filosófica. Sócrates será o inimigo mais temível dessa posição. Este é o começo do movimento filosófico de Atenas, que culmina nos séculos quinto e quarto, tal qual, posteriormente, veremos. 2. O APOGEU GREGO – Sócrates (Σωκράτης: 469 a.C.-399 a.C.), Platão (Πλάτων: 428/427- 348/347 a.C.) e Aristóteles (Ἀριστοτέλης: 384 a.C.-322 a.C.) formam o triunvirato dos grandes filósofos gregos. O primeiro (Sócrates), com seu método "maiêutico" e sua teoria do conceito; o segundo (Platão), com sua teoria das ideias e seu estilo literário (dialogista); e o terceiro (Aristóteles), com a estruturação dos principais ramos filosóficos, como a Lógica, a Metafísica, a Ética, a Psicologia racional e a Política; todos eles elevaram a Filosofia para um posto de primeira ordem. Doravante, todos os filósofos tornam-se credores das contribuições desses gênios. Em certos autores, é clara a influência de Platão ou de Aristóteles. Sendo que, ambos os filósofos, tiveram influência absoluta de Sócrates, uma vez que Platão fora seu discípulo, e Aristóteles discípulo de Platão. A Idade Média, por exemplo, foi toda ela, em sua gênese e desenvolvimento, alicerçada no pensamento e nas ideias platônicas; tal era histórica é caracterizada pela luta em favor de um ou de outro autor; o platonismo tomou precedência nos primeiros séculos do cristianismo; somente após o décimo século Aristóteles foi redescoberto. 3. A FILOSOFIA CRISTÃ MEDIEVAL - Santo Agostinho (354 a.C.-430 a.C.) se destaca, no quinto século, com sua teoria da iluminação e a aplicação da teoria platônica ao Cristianismo. No século XIII, São Tomás de Aquino (1225-1274), sintetiza Aristóteles com o Cristianismo. Os dois autores formam o núcleo da filosofia cristã em seus respectivos séculos. A escolástica teve seu tempo de decadência. Se mencionam, principalmente, dois autores: João Duns Escoto (1266-1308) e Guilherme de Ockham (1285-1347). O primeiro é o "Doutor Sutil ", e o segundo cai em um fideísmo e um nominalismo, para todos os conceitos criticáveis. Em uma segunda parte, tentaremos explicar os respectivos pensamentos dos autores mencionados, e outros que pertencem ao mesmo tempo, antigos e medievais. Naquela época, a Filosofia era puramente realista, aplicada ao mundo e ao homem. Somente na Idade Moderna, a Filosofia assumirá o problema do conhecimento como a base e o começo de todo filosofar. 4. A FILOSOFIA RACIONALISTA (MODERNA) - Na Idade Moderna, sobressai o racionalismo de Descartes (1596-1650) prolongado, então, com Malebranche (1638-1715) (ocasionalismo), Espinosa (1632 -1677) (panteísmo) e Leibniz (1646-1716) (teoria das mônadas). Estamos nos séculos XVII e XVIII. A atenção será focada nas disputas filosóficas da corrente empirista contra a racionalista. 5. A FILOSOFIA EMPIRISTA – O empirismo é florescido, principalmente, na Inglaterra. Francis Bacon (1561-1626), primeiro, e depois Locke (1632-1704) com sua rejeição de ideias inatas, Berkeley (1685-1753) com postura e ideias paradoxais, também idealistas e Hume (1711-1776), com suas famosas críticas contra o princípio da causalidade e o conceito de substância, são os principais autores. 6. KANT E OS IDEALISTAS ALEMÃES - Como a tentativa de sintetizar o racionalismo e empirismo, está a teoria de Kant (1724-1804), no século XVIII. Para o seu gênio seguido pelos três idealistas alemães mais importantes: Fichte (1762-1814) (idealismo subjetivo), Schelling (1775-1854) (idealismo objetivo) e Hegel (1770-1831) (idealismo absoluto). Esses Autores representam o ápice da especulação filosófica. A análise, a profundidade, a complexidade da expressão e o espírito sistemático são as características do gênio alemão idealista. 7. OS FILÓSOFOS DO SÉCULO XIX - Antes de tudo, é necessário mencionar, no século dezenove, aos dois grandes críticos de Hegel, que são Kierkegaard (1813-1855) (precursor do existencialismo) e Marx (1818-1883) (com seu materialismo dialético). O próximo é outro casal: Nietzsche (1844-1900) (teoria do Super-homem) e Schopenhauer (1788-1860) (com seu absoluto pessimismo). Comte (1798-1857) com sua doutrina positivista, completará o quadro desses filósofos. Numa outra oportunidade, vamos desmembrar sobre o pensamento e principais ideias acerca desses autores. 8. OS FILÓSOFOS DO SÉCULO XX - Antes de tudo, há um autor que iluminou a filosofia do século XX: Edmund Husserl (1859-1938), fundador do método fenomenológico. Em seguida, existem dois fluxos que são derivados diretamente de Husserl, a saber, o existencialismo e a axiologia. Dentro da corrente axiológica, estudaremos Scheler (1874-2928). Por outro lado, o existencialismo tem quatro autores principais; dois são alemães: Heidegger (1889-1976) e Jaspers (1883-1969); e os demais são franceses: Sartre (1905-1980) e Marcel (1889-1973). Heidegger insiste em que seu tema tratado em sua filosofia não é a unicidade do homem, mas o ser em geral. Jaspers é famoso por seu conceito de transcendência (Deus). Sartre é um antiteísta sincero, e seu existencialismo é definido como um pensamento que assume todas as consequências da negação de Deus. Em contraste, Gabriel Marcel é um filósofo Católico, que conseguiu uma análise profunda das situações humanas, que aparecem em íntima concordância com as verdades cristãs. Vamos terminar com Russell (1872-1970), autor básico do positivismo lógico.

RESUMO A bovinocultura sempre esteve atrelada ao desenvolvimento do Brasil e, pensando no avanço, as exigências da máxima eficiência nos sistemas de criação foi pautada na forma de como conseguir realizar a reprodução de bovinos com ênfase na eficiência econômica e reprodutiva. O objetivo deste trabalho é elucidar as principais biotecnologias que auxiliam na maior produtividade reprodutiva de bovinos. Dessa forma, o estudo foi realizado usando artigos do banco de dados do Google acadêmico e SciELO, além de livros do acervo (...) pessoal e sites oficiais. Com o manejo reprodutivo aplicado na bovinocultura, é possível identificar pontos a serem melhorados e implantação de práticas que auxiliam no incremento da eficiência reprodutiva como a estação de monta, que concentra a fertilização dos animais em uma determinada época do ano, o uso do índice de escore corporal, o qual consegue determinar a viabilidade da vaca a ser fertilizada, e a identificação da idade a puberdade, na qual a novilha com 60% de peso vivo quando adulta pode estar apta para reprodução, indicando que a nutrição é um fator importante para reduzir o intervalo entre partos, bem como na indução da precocidade, que ainda pode ser maximizada por uso de bioestimuladores. Assim como a implantação do uso de biotecnologias, que podem adicionar aos planteis, indivíduos geneticamente superiores, saudáveis e eficientes. Dentre as biotecnologias, a inseminação artificial é a mais usada no Brasil, com capacidade de fertilizar vacas com sêmen de touros de genética superior, nacional ou importado. Podem ser citadas ainda as técnicas de transferência de embriões e produção in vitro de embriões como tecnologias a serviço do desenvolvimento da eficiência reprodutiva. A utilização de protocolos hormonais no ciclo estral objetiva a sincronização do estro das vacas para facilitar o emprego das biotecnologias. São vários os protocolos usados para essa finalidade, sendo Ovsynch a base de GnRH e prostaglandina com até 50% de eficácia, protocolos à base de estradiol e progesterona com eficácia de até 86,6%, e protocolos que usam gonadotrofina coriônica equina (eCG), indicados para animais magros por condicionar maior diâmetro folicular, o qual é relacionado com aumento na taxa de prenhez. Dessa maneira, as práticas e tecnologias citadas neste estudo são usadas na reprodução assistida de bovinos. PALAVRAS-CHAVE: Criopreservação. Estro. Gestação. Hipófise. Nutrição. ABSTRACT Cattle farming has always been linked to Brazil’s development and, thinking about advancement, the requirements for maximum efficiency in breeding systems was based on how to achieve the reproduction of cattle with an emphasis on economic and reproductive efficiency. The objective of this work is to elucidate the main biotechnologies that help in the greater reproductive productivity of cattle. Thus, the study was done using articles from the Academic Google and SciELO databases, as well as books from the personal collection and official websites. With the reproductive management applied in cattle farming, it is possible to identify points to be improved and implement practices that help to increase reproductive efficiency, such as the breeding season, which concentrates the fertilization of animals at a certain time of year, use of the body score index, which can determine the viability of the cow to be fertilized, identification of age at puberty, in which the heifer with 60% live weight as an adult may be suitable for reproduction, indicating that nutrition is an important factor in reducing the interval between births, as well as in inducing precocity, which can still be maximized by the use of biostimulators. As well as the implementation of the use of biotechnology, which can add genetically superior, healthy and efficient individuals to the breeding stock. Among the biotechnologies, artificial insemination is the most used in Brazil, with the capacity to fertilize cows with superior genetic bull semen, whether national or imported. Embryo transfer techniques and in vitro embryo production can also be cited as technologies in the service of the development of reproductive efficiency. The use of hormonal protocols in the estrous cycle aims at synchronizing the estrus of cows to facilitate the use of biotechnologies. There are several protocols used for this purpose, with Ovsynch being based on GnRH and prostaglandin with up to 50% efficacy, protocols based on estradiol and progesterone with efficacy of up to 86.6%, and protocols that use equine chorionic gonadotropin (eCG), indicated for lean animals because they condition larger follicular diameter, which is related to an increase in the pregnancy rate. Thus, the practices and technologies mentioned in this study can help the assisted reproduction of cattle. KEYWORDS: Cryopreservation. Estro. Gestation. Hypophysis.

You may not know me well enough to evaluate me in terms of my moral character, but I take it you believe I can be evaluated: it sounds strange to say that I am indeterminate, neither good nor bad nor intermediate. Yet I argue that the claim that most people are indeterminate is the conclusion of a sound argument—the indeterminacy paradox—with two premises: (1) most people are fragmented (they would behave deplorably in many and admirably in many other situations); (2) (...) fragmentation entails indeterminacy. I support (1) by examining psychological experiments in which most participants behave deplorably (e.g., by maltreating “prisoners” in a simulated prison) or admirably (e.g., by intervening in a simulated theft). I support (2) by arguing that, according to certain plausible conceptions, character evaluations presuppose behavioral consistency (lack of fragmentation). Possible reactions to the paradox include: (a) denying that the experiments are relevant to character; (b) upholding conceptions according to which character evaluations do not presuppose consistency; (c) granting that most people are indeterminate and explaining why it appears otherwise. I defend (c) against (a) and (b). (shrink)

This essay interprets Butler’s distinction between identity in the loose and popular sense and in the strict and philosophical sense. Suppose there are different standards for counting the same things. Then what are two distinct things counting strictly may be one and the same thing counting loosely. Within a given standard identity is one-one. But across standards it is many-one. An alternative interpretation using the parts-whole relation fails, because that relation should be understood as many-one identity. Another alternative making identity (...) relative to sort fails, because whole and parts can be of the same sort. (shrink)

Against caricatures of the poet-philosopher Friedrich Schiller as an unoriginal popularizer of Kant, or a forerunner of totalitarianism, Frederick Beiser reinterprets him as an innovative, classical republican, broadening his analysis to include Schiller’s poetry, plays, and essays not widely available in English translation, such as the remarkable essay, “On Grace and Dignity.” In that spirit, the present article argues that the latter text, misperceived by Anglophone critics as self-contradictory, is better understood as centering on gender and dance. In brief, grace (...) is a virtuous power of beautiful gestures associated with women, while dignity is a power of sublime gestures associated with men, and the improvised combination thereof is a divinely androgynous power of gesture that I term “stateliness,” in a three-step choreography of aesthetic education.

This is an encyclopedia article about epistemic closure principles. The article explains what they are, their various philosophical uses, how they are argued for or against, and provides an overview of the related literature.

I want to argue that self-deception is a species of a more general phenomenon, which I shall call pseudorationality, which in turn is necessitated by what I shall describe as our highest-order disposition to literal self-preservation. By "literal self-preservation," I mean preservation of the rational intelligibility of the self, in the face of recalcitrant facts that invariably threaten it.

In recent analytic literature on the Trinity we have seen a variety of "social" models of the Trinity. By contrast there are few "non-­‐social" models. One prominent "non-­‐social" view is Brian Leftow's "Latin Trinity." I argue that the name of Leftow's model is not sufficiently descriptive in light of diverse models within Latin speaking theology. Next, I develop a new "non-­‐social" model that is inspired by Richard of St. Victor's description of a person in conjunction with my appropriating insights about (...) indexicals from David Kaplan and John Perry. I point out that the copula in tokens of statements like, "I am the Father," is an ambiguous term and when used by a certain divine person a different proposition is affirmed. Central to this model is the claim that the copula bears the "is of identity" and the "is of numerical sameness without identity." Further, I show that Leftow's model employs two concepts of "person," a Lockean one and a Boethian one, and mine employs Richard of St. Victor's. I describe Leftow's model as a "hard non-­‐social" model and mine as a "soft non-­‐social" model that is nearer to some social models. I conclude that Leftow's model is not the lone candidate among "non-­‐social" models and that the variety of "non-­‐social" models has yet to be exhausted. (shrink)

Ideas for integrating AI into politics are now emerging and advancing at accelerating pace. This chapter highlights a few different varieties and show how they reflect different assumptions about the value of democracy. We cannot make informed decisions about which, if any, proposals to pursue without further reflection on what makes democracy valuable and how current conditions fail to fully realize it. Recent advances in political philosophy provide some guidance but leave important questions open. If AI advances to a state (...) where it can secure superior political outcomes, leading perspectives in political philosophy suggest that democracy may become obsolete. If we find this suggestion troubling, we need to put the case for democracy on stronger foundations. (shrink)

As a retired professor, I join in the growing concerns among educators, and others, about plagiarism, especially now that AI tools like ChatGPT are so readily available. However, I feel more caution is needed, regarding temptations to rely on supposed automatic detection tools, like Turnitin, to solve the problems. Students can be unfairly accused if such tools are used unreflectingly. The Toronto Star's online version of this published Op Ed is available at the link shown below. The version attached here (...) is a pre-print, which also includes annotations for my references, which are not displayed in the published version. (shrink)

It is often claimed that the greatest value of the Bayesian framework in cognitive science consists in its unifying power. Several Bayesian cognitive scientists assume that unification is obviously linked to explanatory power. But this link is not obvious, as unification in science is a heterogeneous notion, which may have little to do with explanation. While a crucial feature of most adequate explanations in cognitive science is that they reveal aspects of the causal mechanism that produces the phenomenon to be (...) explained, the kind of unification afforded by the Bayesian framework to cognitive science does not necessarily reveal aspects of a mechanism. Bayesian unification, nonetheless, can place fruitful constraints on causal–mechanical explanation. 1 Introduction2 What a Great Many Phenomena Bayesian Decision Theory Can Model3 The Case of Information Integration4 How Do Bayesian Models Unify?5 Bayesian Unification: What Constraints Are There on Mechanistic Explanation?5.1 Unification constrains mechanism discovery5.2 Unification constrains the identification of relevant mechanistic factors5.3 Unification constrains confirmation of competitive mechanistic models6 ConclusionAppendix.

Construing the instantiation of a universal by a particular in terms of my theory of aspects resolves the basic mystery of this "non-relational tie", and gives theoretical unity to the four characteristics of instantiation discerned by Armstrong. Taking aspects as distinct in a way akin to Scotus's formal distinction, I suggest that instantiation is the sharing of an aspect by a universal and a particular--a kind of partial identity. This approach allows me to address Plato's multiple location and One over (...) Many problems, Bradley's problem concerning the instantiation of relations, and the problem of change. (shrink)

Imperatives cannot be true or false, so they are shunned by logicians. And yet imperatives can be combined by logical connectives: "kiss me and hug me" is the conjunction of "kiss me" with "hug me". This example may suggest that declarative and imperative logic are isomorphic: just as the conjunction of two declaratives is true exactly if both conjuncts are true, the conjunction of two imperatives is satisfied exactly if both conjuncts are satisfied—what more is there to say? Much more, (...) I argue. "If you love me, kiss me", a conditional imperative, mixes a declarative antecedent ("you love me") with an imperative consequent ("kiss me"); it is satisfied if you love and kiss me, violated if you love but don't kiss me, and avoided if you don't love me. So we need a logic of three -valued imperatives which mixes declaratives with imperatives. I develop such a logic. (shrink)

Biological evolution is a complex blend of ever changing structural stability, variability and emergence of new phe- notypes, niches, ecosystems. We wish to argue that the evo- lution of life marks the end of a physics world view of law entailed dynamics. Our considerations depend upon dis- cussing the variability of the very ”contexts of life”: the in- teractions between organisms, biological niches and ecosys- tems. These are ever changing, intrinsically indeterminate and even unprestatable: we do not know ahead of (...) time the ”niches” which constitute the boundary conditions on selec- tion. More generally, by the mathematical unprestatability of the ”phase space”, no laws of mo- tion can be formulated for evolution. We call this radical emergence, from life to life. The purpose of this paper is the integration of variation and diversity in a sound concep- tual frame and situate unpredictability at a novel theoretical level, that of the very phase space. Our argument will be carried on in close comparisons with physics and the mathematical constructions of phase spaces in that discipline. The role of symmetries as invariant preserving transformations will allow us to under- stand the nature of physical phase spaces and to stress the differences required for a sound biological theoretizing. In this frame, we discuss the novel notion of ”enablement”. Life lives in a web of enablement and radical emergence. This will restrict causal analyses to differential cases. Mutations or other causal differ- ences will allow us to stress that ”non conservation princi- ples” are at the core of evolution, in contrast to physical dynamics, largely based on conservation principles as sym- metries. Critical transitions, the main locus of symmetry changes in physics, will be discussed, and lead to ”extended criticality” as a conceptual frame for a better understanding of the living state of matter.

PHILOSOPHY OF SCIENCE, vol. 52, number 1, pp.44-63. R.M. Nugayev, Kazan State |University, USSR. -/- THE HISTORY OF QUANTUM THEORY AS A DECISIVE ARGUMENT FAVORING EINSTEIN OVER LJRENTZ. -/- Abstract. Einstein’s papers on relativity, quantum theory and statistical mechanics were all part of a single research programme ; the aim was to unify mechanics and electrodynamics. It was this broader program – which eventually split into relativistic physics and quantummmechanics – that superseded Lorentz’s theory. The argument of this paper is (...) partly historical and partly methodological. A notion of “crossbred objects” – theoretical objects with contradictory properties which are part of the domain of application of two different research programs – is developed that explains the dynamics of revolutionary theory change.

Binding specificity is a centrally important concept in molecular biology, yet it has received little philosophical attention. Here I aim to remedy this by analyzing binding specificity as a causal property. I focus on the concept’s role in drug design, where it is highly prized and hence directly studied. From a causal perspective, understanding why binding specificity is a valuable property of drugs contributes to an understanding of causal selection—of how and why scientists distinguish between causes, not just causes from (...) noncauses. In particular, the specificity of drugs is precisely what underwrites their value as experimental interventions on biological processes. (shrink)

Notions of procedural justice alone are sufficient to support evidentiary exclusions in a wide variety of legal and law-like institutions that focus on conflict resolution, including courts. Special attention is paid to the relevance and need for exclusion of parties’ own assessments of the value of their claims.

The purpose of this paper is to show that, if Kant’s universalization formulations of the Categorical Imperative are our only standards for judging right from wrong and permissible from impermissible, then we have no obligations. I shall do this by examining five different views of how obligations can be derived from the universalization formulations and arguing that each one fails. I shall argue that the first view rests on a misunderstanding of the universalization formulations; the second on a misunderstanding of (...) the concept of an obligation; the third on a misunderstanding of the concept of a maxim; the fourth on a misunderstanding of the limits of action description; and the fifth on a misunderstanding of the universalization formulations again.

One cannot have the concept of a red object without having the concept of an extended object. But the word "red" doesn't contain the word "extended." In general, our concepts are interconnected in ways in which the corresponding words are not interconnected. This is not an accidental fact about the English language or about any other language: it is inherent in what a language is that the cognitive abilities corresponding to a person's abilities to use words cannot possibly be reflected (...) in semantic relations holding among those words. This fact in its turn is a consequence of the fact that expressions are, whereas concepts are not, digital structures, for which reason the ways in which cognitive abilities interact cannot possibly bear any significant resemblance to the ways in which expressions interact. Consequently, there is no truth to the contention that our thought-processes are identical with, or bear any resemblance to, the digital computations that mediate computer-activity. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:This Universalism Which Is Not OneLinda M. G. Zerilli (bio)Ernesto Laclau. Emancipation(s). London: Verso, 1996.Judging from the recent spate of publications devoted to the question of the universal, it appears that, in the view of some critics, we are witnessing a reevaluation of its dismantling in twentieth-century thought. One of the many oddities about this “return of the universal” 1 is the idea that contemporary engagements with it are (...) more or less of a piece, and that they reflect a growing consensus that poststructuralist political theories are incapable of generating a viable alternative to the collective fragmentation that characterizes late modernity. 2 The putative return to the universal marks, on this view, both a homecoming to Enlightenment ideals—purified of their more poisonous elements, of course—and a reconciliation of sorts between those who refuted these ideals and those who sought to realize them. Now that “we” all know and agree that poststructuralism is critically valuable but politically bankrupt; now that we all know and agree that the “old universal” was indeed a “pseudo-universal,” so the homecoming narrative goes; we can get on with the project of constructing a “new universal.” 3 This authentic universal would really be inclusive of all people, regardless of race, class, gender, sexuality, ethnicity, nationality, and whatever else attaches to the “embarrassing etcetera” that, as Judith [End Page 3] Butler reminds us, inevitably accompanies such gestures of acknowledging human diversity.Before signing on to this felicitous agreement about “the necessity of universalism,” we may wish to know whether we have anything like a minimal agreement in language, that is, whether we who speak of this universal are even speaking about the same thing. Apart from the not insignificant problem of translating from a philosophical to a political idiom, the whole question of this agreement is virtually occluded by the rush to rescue politics from the virulent particularisms that admit no common ground or sense of collective belonging. Presented in terms of the familiar binary couple, the choice between universalism and particularism seems settled by merely pointing to global and domestic political realities. Universalism is the only alternative to social fragmentation, wild child of the collapse of communism, the rise of deadly nationalisms, and the multiculturalist romance with particularism. To invoke the name of the universal in any affirmative sense is already to sign on to the political diagnosis and its solution.One of the many virtues of Ernesto Laclau’s Emancipation(s) is that it offers both an alternative to the binarisms spawned by the “return” to the universal (for example, false universalism/true universalism) and a trenchant critique of the original binary couple itself (universalism/ particularism). Demonstrating the imbrication of the universal and the particular, Laclau shows why it is a matter not of choosing one over the other but of articulating, in a scrupulously political sense, the relation between the two. He thus explicitly rejects the notion that this relation is one of mutual exclusion, and shows that the tendency to see it as just that has led to the impasse of the contemporary debate, an impasse that is glossed over in some highly visible academic cases by proclaiming the necessary return to the universal. Although the language of universalism as spoken by Laclau searches for some common ground between particularists and universalists, it is more by way of articulating their mutual contamination, that is, how each is rendered impure by the irreducible presence of the other.The Problem of UniversalsLaclau situates his collection of essays in the context of the increasingly polarized debate over multiculturalism, a debate in which the classical universalism of the philosophical tradition has come under serious question. Reading his essays, one comes to see the deep dependence of the entire contemporary discussion on this tradition, even when its metaphysical assumptions are explicitly rejected (as, say, in the work of Seyla Benhabib) or insufficiently comprehended (as in most of the popularized political discourse). Laclau’s book can help us to see that the political question of universalism cannot be posed properly as long as it remains tethered to the classical philosophical “problem of universals.” At stake in sorting out the affinities and...

We need modal imagination in order to extend our conception of reality - and, in particular, of human beings - beyond our immediate experience in the indexical present; and we need to do this in order to preserve the significance of human interaction. To make this leap of imagination successfully is to achieve not only insight but also an impartial perspective on our own and others' inner states. This perspective is a necessary condition of experiencing compassion for others. This is (...) the primary thesis I will try to defend in this discussion. (shrink)

Background If trials of therapeutic interventions are to serve society's interests, they must be of high methodological quality and must satisfy moral commitments to human subjects. The authors set out to develop a clinical - trials compendium in which standards for the ethical treatment of human subjects are integrated with standards for research methods. Methods The authors rank-ordered the world's nations and chose the 31 with >700 active trials as of 24 July 2008. Governmental and other authoritative entities of the (...) 31 countries were searched, and 1004 English-language documents containing ethical and/or methodological standards for clinical trials were identified. The authors extracted standards from 144 of those: 50 designated as ‘core’, 39 addressing trials of invasive procedures and a 5% sample of the remainder. As the integrating framework for the standards we developed a coherent taxonomy encompassing all elements of a trial's stages. Findings Review of the 144 documents yielded nearly 15 000 discrete standards. After duplicates were removed, 5903 substantive standards remained, distributed in the taxonomy as follows: initiation, 1401 standards, 8 divisions; design, 1869 standards, 16 divisions; conduct, 1473 standards, 8 divisions; analysing and reporting results, 997 standards, four divisions; and post-trial standards, 168 standards, 5 divisions. Conclusions The overwhelming number of source documents and standards uncovered in this study was not anticipated beforehand and confirms the extraordinary complexity of the clinical trials enterprise. This taxonomy of multinational ethical and methodological standards may help trialists and overseers improve the quality of clinical trials, particularly given the globalisation of clinical research.

Minimal Negation is defined within the basic positive relevance logic in the relational ternary semantics: B+. Thus, by defining a number of subminimal negations in the B+ context, principles of weak negation are shown to be isolable. Complete ternary semantics are offered for minimal negation in B+. Certain forms of reductio are conjectured to be undefinable (in ternary frames) without extending the positive logic. Complete semantics for such kinds of reductio in a properly extended positive logic are offered.

“Erotism and Censorship“ offers an introduction to the history of picture postcards and explores the German censorship until 1930. The specificity of the medium to react to the desires of the clients (mostly male) and to shape them simultaneously is explained in interpretations of examples. A documentary part presents a selection of texts about reproduction technologies. These texts were originally published in journals for collectors of postcards.

This paper will highlight Maathai’s insights regarding empowerment, tracing several important themes in her approach, namely, empowerment’s relationship to self esteem, teamwork, and political action, its ambivalent relationship to formal education, and the role of cultural traditions in providing alternatives to colonial-era cultural impositions and current exploitative effects of neo-liberal capitalism. After reviewing Maathai’s thoughts on each of these topics, I will briefly draw upon other East African thinkers and Africanists’ studies of East African communities to present corroborating evidence for (...) Maathai’s views or for challenges to her position. Listening to the perspectives of Maathai and other East Africans provides several important correctives to current popular uses of the term “empowerment.”. (shrink)

In this paper, I propose to look closely at certain crucial aspects of the logic of Rawls' argument in Political Liberalism and related subsequent writings. Rawls' argument builds on the notion of comprehensiveness, whereby a doctrine encompasses the full spectrum of the life of its adherents. In order to show the mutual conflict and irreconcilability of comprehensive doctrines, Rawls needs to emphasise the comprehensiveness of doctrines, as their irreconcilability to a large extent emanates from that comprehensiveness. On the other hand, (...) in order to show the possibility and plausibility of the political liberal solution he needs to emphasise that most of these doctrines are reasonable: i.e., they are willing to cede a portion of their authority to political liberalism for the right reasons. Yet, if they are willing to cede a portion of their authority to a political conception they cannot be as comprehensive as we initially thought they were. All these elements highlight the tension in the argument itself. I suggest that many of these tensions can be removed by making Rawls' account more flexible. In this context I propose certain amendments to Rawls' account, which may overcome some of the tensions mentioned above. (shrink)

In this paper, I open an inquiry that provides a catalyst for the inauguration of African Philosophy of Medicine and Bioethics (APMB) as a full-fledged academic pursuit. I situate this inquiry within the quest of early professional African philosophers for a stirring of the course of contemporary African philosophy along the path of critically retrieving, clarifying, and articulating aspects of traditional African culture and practices in the light of social pluralism and modernization. The case I make for the establishment of (...) this discipline and my effort to delineate its nature, scope, and method hinge on three important realities: (i) The existence of African Traditional Medicine (ATM); (ii) the existence of philosophical puzzles in ATM that require conceptual, metaphysical, epistemological, ethical, and socio-political analyses; and (iii) the need to carry out this analysis in the context of the twenty-first-century reality of medical pluralism and globalization. Solidifying my effort to map out the landscape of this new enterprise, in the concluding part of this paper, I make recommendations on the direction the discipline is to take if it must fulfil its goal of providing a framework for the improvement of medical knowledge and practice in contemporary Africa.

Every quantum state can be represented as a probability distribution over the outcomes of an informationally complete measurement. But not all probability distributions correspond to quantum states. Quantum state space may thus be thought of as a restricted subset of all potentially available probabilities. A recent publication (Fuchs and Schack, arXiv:0906.2187v1, 2009) advocates such a representation using symmetric informationally complete (SIC) measurements. Building upon this work we study how this subset—quantum-state space—might be characterized. Our leading characteristic is that the inner (...) products of the probabilities are bounded, a simple condition with nontrivial consequences. To get quantum-state space something more detailed about the extreme points is needed. No definitive characterization is reached, but we see several new interesting features over those in Fuchs and Schack (arXiv:0906.2187v1, 2009), and all in conformity with quantum theory. (shrink)

Most moral theories share certain features in common with other theories. They consist of a set of propositions that are universal, general, and hence impartial. The propositions that constitute a typical moral theory are (1) universal, in that they apply to all subjects designated as within their scope. They are (2) general, in that they include no proper names or definite descriptions. They are therefore (3) impartial, in that they accord no special privilege to any particular agent's situation which cannot (...) be justified under (2) and (3). These three features do not distinguish moral theories from other theories, nor indeed from most general categorical propositions we assert. Yet, in recent years, these features of moral theories have been the target of a certain concerted and sustained criticism, namely, that to be committed to such a moral theory, or to aspire to act in accordance with its requirements, results in what has come to be known as moral alienation. Moral alienation, according to this criticism, consists in (i) viewing one's ground projects from an impersonal, "moral point of view" engendered by one's acceptance of the theory; (ii) being prepared to sacrifice these projects to the requirements of moral principle; and (iii) making such a sacrifice specifically and self-consciously in order to conform to these requirements. Moral alienation is said to manifest itself in one (or both) of two ways, depending on the nature of the project thus susceptible to sacrifice. One may be alienated from oneself, if the project consists of tastes, convictions, or aspirations that are centrally definitive of one's self. In this case one's commitment to the project can be at best conditional on its congruence with one's moral theory. It is claimed that this must make for a rather tepid and unenthusiastic commitment indeed. Alternatively, one may be alienated from others, if the project is an interpersonal relationship such as a friendship, marriage, or collegial relationship. In this case one's responses to the other are motivated by one's awareness of what one's moral theory requires. It is claimed that this obstructs a genuine and unmediated emotional response to the other as such. My aim here will be to argue that this very compelling criticism - call it the moral-alienation criticism - is nevertheless misdirected. The real culprit is not any particular moral theory, but rather a certain familiar personality type that may or may not adopt it. (shrink)

Alongside science and law, argumentation is also of central importance in everyday life. But what characterizes a good argument? This question has occupied philosophers and psychologists for centuries. The theory of Bayesian argumentation is particularly suitable for clarifying it, because it allows us to take into account in a natural way the role of uncertainty, which is central to much argumentation. Moreover, it offers the possibility of measuring the strength of an argument in probabilistic terms. One way to do this, (...) implicit in much work, is to identify the strength of an argument with the degree to which the premises of the argument confirm the conclusion. We criticize this prima facie plausible proposal and suggest instead that the strength of an argument has something to do with how much the premises and the conclusion of the argument cohere with each other. This leads to a new probabilistic measure whose properties we examine in more detail. (shrink)

In “The Irrelevance of the Diachronic Money-Pump Argument for Acyclicity,” The Journal of Philosophy CX, 8 (August 2013), 460-464, Johan E. Gustafsson contends that if Davidson, McKinsey and Suppes’ diachronic money-pump argument in their "Outlines of a Formal Theory of Value, I," Philosophy of Science 22 (1955), 140-160 is valid, so is the synchronic argument Gustafsson himself offers. He concludes that the latter renders irrelevant diachronic choice considerations in general, and the two best-known diachronic solutions to the money pump problem (...) in particular. I argue here that this reasoning is incorrect, and that Gustafsson’s synchronic argument is faulty on independent grounds. Specifically, it is based on a false analogy between the derivation of a synchronic ordinal ranking from a transitive series of pairwise comparisons, and the putative derivation of such a ranking from an intransitive series. The latter is not possible under the assumption of revealed preference theory, and is highly improbable even if that assumption is rejected. Moreover, Gustafsson’s argument raises issues of fidelity to the historical texts that must be addressed. I conclude that the money pump, and cyclical choice more generally, are necessarily diachronic; and therefore that the two best-known diachronic solutions to the money pump problem remain relevant.

The host of SUSY(supersymmetry) based string theories is considered. Superstrings are comprehended as possible candidates on Quantum Gravity basic objects. It is argued that superstring theories constitute mainly mathematical progress and can reconcile general relativity with quantum field theory at best. Yet they cannot provide the genuine synthesis. Superstring unification of all the four forces at hand is a formal one . It is contended that genesis and proliferation of superstrings can better be described not by philosophy of science models (...) but in terms of modern sociology of science. The formal character of gravity and quantum fields fusion and the lack of experimental verification make the transition to superstring theories ad hoc in Lakatosian standards. Possible way of explanation is proposed based on social interests conception of Andrew Pickering. -/- Key words: superstrings, unification, Kaluza-Klein, sociology of science . (shrink)

This work introduces the framework for selecting architecture in 5G networks, considering various technological, performance, economic, and operational factors. With the emergence of 5G technology, the architecture selection process has become pivotal in meeting diverse requirements for ultra-high-speed connectivity, low latency, scalability, and diverse service demands. The evaluation comprehensively analyses different architecture options, including centralized, distributed, cloud-based, and virtualized architectures. Factors such as network performance, scalability, cost-effectiveness, security, and compatibility are considered within a multi-criteria decision-making framework. Findings reveal each architecture (...) option's diverse strengths and limitations, emphasizing the importance of aligning architectural choices with specific use cases, deployment scenarios, and business objectives. We used the concept of multi-criteria decision-making (MCDM) methodology to control the various criteria. We used the single-valued neutrosophic set (SVNS) to deal with vague and inconsistent data. The SVNS is integrated with the hyperSoft set. The proposed methodology uses a single-valued neutrosophic hyperSoft set (SVNHSS) to select the best 5G architecture. We used the VIKOR method as an MCDM method to rank the alternatives. The proposed framework provides stakeholders with a structured methodology to evaluate and prioritize architecture options, facilitating informed decision-making in the complex landscape of 5G network deployments.

Software piracy is older than the PC and has been the subject of several studies, which have found it to be a widespread phenomenon in general, and among university students in particular. An earlier study by Cohen and Cornwell from a decade ago is replicated, adding questions about downloading music from the Internet. The survey includes responses from 224 students in entry-level courses at two schools, a nondenominational suburban university and a Catholic urban college with similar student profiles. The study (...) found that there has been few if any changes in student opinions regarding the unauthorized duplication of copy- righted materials. Students generally felt that copying commercial software and downloading music from the Internet was acceptable and found that there was no significant correlation between student attitudes and their school’s religious affiliation or lack thereof. Additionally, the study found that a small but significant percentage of respondents considered the other questionable behaviors as ethically acceptable. Finally, the reasons for these attitudes are discussed as well as what colleges can do to correct the situation. (shrink)

I propose an approach to naturalized philosophy of science that takes the social nature of scientific practice seriously. I criticize several prominent naturalistic approaches for adopting "cognitive individualism", which limits the study of science to an examination of the internal psychological mechanisms of scientists. I argue that this limits the explanatory capacity of these approaches. I then propose a three-level model of the social nature of scientific practice, and use the model to defend the claim that scientific knowledge is socially (...) produced. (shrink)

Recursion or self-reference is a key feature of contemporary research and writing in semiotics. The paper begins by focusing on the role of recursion in poststructuralism. It is suggested that much of what passes for recursion in this field is in fact not recursive all the way down. After the paradoxical meaning of radical recursion is adumbrated, topology is employed to provide some examples. The properties of the Moebius strip prove helpful in bringing out the dialectical nature of radical recursion. (...) The Moebius is employed to explore the recursive interplay of terms that are classically regarded as binary opposites: identity and difference, object and subject, continuity and discontinuity, etc. To realize radical recursion in an even more concrete manner, a higher-dimensional counterpart of the Moebius strip is utilized, namely, the Klein bottle. The presentation concludes by enlisting phenomenological philosopher Maurice Merleau-Ponty’s concept of depth to interpret the Klein bottle’s extra dimension. (shrink)

After some years (or millennia) most works would no longer be considered eligible for "review." But an exception is called for, if the thrust of an older work is closely paralleled in a much more modern piece, as is the case between Plato's Theaetetus and Richard Rorty's acclaimed, and more recent volume, Philosophy and the Mirror of Nature. To fully understand and appreciate Rorty 's contribution to the subjects he raises, one must study his book in conjunction with Plato's Theaetetus-where (...) very similar issues have been discussed before. Both works concern a central question for philosophy: "What is knowledge?" The discussants in Plato's dialogue the Theaetetus, never do succeed in finding a satisfactory definition for knowledge, yet they at least realize to avoid thinking they know about the subject when, in fact, they lack that knowledge. Since Rorty explores some new (and not so new) ideas on these topics, Plato's discussants ask him a few questions. (Reprinted from original in Antioch Review). (shrink)

Goodman draws together, in this memoir, his explorations of meaning and coincidence, and his lived experiences of chance, and his professional experiences teaching, writing, and consulting about risk. The book opens by describing the author's life-changing encounter with a Zen Buddhist monk in 1977, over a cup of tea. Returning to his beginnings, Goodman recounts his coming-of-age, from participating the 1960’s U.S. protests and Vietnam-War resistance, to finally settling down in Canada. He describes his role in a supporting, silent vigil (...) around Willard Straight Hall at Cornell University, the night after it had been occupied by protestors, and his later application for Conscientious Objector status, following the U.S. draft lottery in 1969. He reflects on the challenges and changes on his road taken, in his career and personal relationships, and in spiritual searches, to share some insights about the seamless nature of chance, and about seeing a Both/And perspective in life that encourages openness to possibilities. -/- .
