The nature and structure of time and time-intervals in physical, chemical and biological systems will be elucidated. The relation and dependence among time, energy and taking place of natural processes will be critically analyzed. The bio-processes taking place in nano-time intervals will be identified. Their relevance to nano-bio-science and nano-bio-technology will be developed and nano-time interval-aspect of nano-sciences and nano-technology will be advanced. -/- .

Since 2004, it has been mandated by law that all Danish undergraduate university programmes have to include a compulsory course on the philosophy of science for that particular program. At the Faculty of Science and Technology, Aarhus University, the responsibility for designing and running such courses were given to the Centre for Science Studies, where a series of courses were developed aiming at the various bachelor educations of the Faculty. Since 2005, the Centre has been running a (...) dozen different courses ranging from mathematics, computer science, physics, chemistry over medical chemistry, biology, molecular biology to sports science, geology, molecular medicine, nano science, and engineering. -/- We have adopted a teaching philosophy of using historical and contemporary case studies to anchor broader philosophical discussions in the particular subject discipline under consideration. Thus, the courses are tailored to the interests of the students of the particular programme whilst aiming for broader and important philosophical themes as well as addressing the specific mandated requirements to integrate philosophy, some introductory ethics, and some institutional history. These are multiple and diverse purposes which cannot be met except by compromise. -/- In this short presentation, we discuss our ambitions for using case studies to discuss philosophical issues and the relation between the specific philosophical discussions in the disciplines and the broader themes of philosophy of science. We give examples of the cases chosen to discuss various issues of scientific knowledge, the role of experiments, the relations between mathematics and science, and the issues of responsibility and trust in scientific results. Finally, we address the issue of how and why science students can be interested in and benefit from mandatory courses in the philosophy of their subject. (shrink)

This paper challenges the first Gettier counterexample to the tripartite account of knowledge. Noting that 'the man who will get the job' is a description and invoking Donnellan's distinction between their 'referential' and 'attributive' uses, I argue that Smith does not actually believe that the man who will get the job has ten coins in his pocket. Smith's ignorance about who will get the job shows that the belief cannot be understood referentially, his ignorance of the coins in his pocket (...) shows that it cannot be understood attributively. An explanation for why Smith appeared to have justified true belief is given by distinguishing between 'belief' and 'belief in truth'. Smith believes the sentence 'the man who will get the job has ten coins in his pocket' to be true (he mistakenly believes that Jones will get the job, of whom he knows that he has ten coins in his pocket) (hence his 'belief'), the sentence is true (hence 'truth'), and he has sufficient reason to assent to it (hence his 'justification'). But he does not believe the proposition expressed. Hence he does not know it either. (shrink)

Artificial intelligence has arrived. In the online world it is already a part of everyday life, sitting invisibly behind a wide range of search engines and online commerce sites. It offers huge potential to enable more efficient and effective business and government but the use of artificial intelligence brings with it important questions about governance, accountability and ethics. Realising the full potential of artificial intelligence and avoiding possible adverse consequences requires societies to find satisfactory answers to these questions. This report (...) sets out some possible approaches, and describes some of the ways government is already engaging with these issues. (shrink)

The development of machine learning and deep learning (DL) in the field of AI (artificial intelligence) is the direct result of the advancement of nano-electronics. Machine learning is a function that provides the system with the capacity to learn from data without being programmed explicitly. It is basically a mathematical and probabilistic model. DL is part of machine learning methods based on artificial neural networks, simply called neural networks (NNs), as they are inspired by the biological NNs that constitute (...) organic brains. Despite its similarity to biological organs such as human brains, major problems arise in trying to attribute moral responsibility to autonomic systems based on hardware including nano-electronic devices, which are sought to replace humans (moral agents) in the context of AI. It is suggested that the required emotional environment which enables actions according to reasons in humans is not witnessed at AI devices. Though AI technology raises an enticing resemblance to human actions, this resemblance is to be considered with a skeptical eye. It is because actions are associated with reasons while causes are connected to operations. Human agents are capable of acting upon their reasons, while AI devices are limited only to operations as they are conditioned by their programming, which is considered as an embodiment of some causes. As moral responsibility goes hand in hand with the capacity to act (according to reasons), attributing moral responsibility to AI devices is revealed to be but a misleading metaphor. (shrink)

Defining Ecosophy (ecological wisdom) like a contemporary philosophy of survival, security and a sustainable Human Development, terrestrial nature and society, the author of this article approaches the correlation between it and the digital version of security in the context of new technologies. Human survival is in connection with the protection, optimal functioning of the natural environment and the development of human society. Human evolution, physical and psychological (the issues of Anthropoecology, a medical-biological science, deals with them), depends on the (...) natural and social environment, on the development of new techniques and technologies. New technologies (nano-, bio-, info-, socio-technologies) can ensure the security and the increasing development of the human being, but they can threaten it too. The author does not deny behaviours, the possibility that human intellect could be non-biological. Moreover, the author believes if it comes to it, that we will not be able to speak about the human species. New technologies like the traditional and less new, are intended to help in solving various problems related to health, society interactions with nature, human society and diverse cultures, societies and states. The philosophy of security and the digital one, like the components of Ecosophy, along with philosophical aspects of Anthropoecology, General Ecology and Social Ecology, needs like any other science or philosophy to elaborate systems of concepts, principles and laws.

RELAÇÃO E EFEITOS BIOQUÍMICO-NUTRICIONAIS SOBRE OS BEZERROS NATIMORTOS EM VACAS Emanuel Isaque Cordeiro da Silva Departamento de Agropecuária – IFPE Campus Belo Jardim [email protected] ou [email protected] WhatsApp: (82)98143-8399 15. NATIMORTOS Por natimortos, entende-se todos aqueles produtos (bezerros/bezerras) que nascem vivos após um tempo de gestação fisiológica normal, mas que morrem nas primeiras 24 horas de vida, ou às vezes nascem mortos, sem evidência clara de que a morte tenha ocorrido 48 horas (ou menos) antes do parto (FRAZER, 2005; GORDON, 1996). (...) Essa evidência, provém das mudanças autolíticas que o produto expelido apresenta. A causa que origina os natimortos é difícil de diagnosticar pela complexa e abundante presença de situações que poderiam levar à apresentação deste quadro. Entre essa complexa explicação etiológica, de origem nutricional podemos enumerar: 15.1 Nitratos e nitritos Um excesso de nitrogênio, seja não proteico ou originado da metabolização proteica excessiva, pode gerar natimortos, uma vez que os nitratos do alimento convertem-se no rúmen em nitritos e depois em amônio, que é excretado ou degradado de diferentes formas. Sob certas condições ambientais, como geadas, secas, granizo, etc. o metabolismo de algumas plantas como a cevada, aveia, milho, pastos e forragens de rápido crescimento não funciona normalmente, e os nitratos acumulam-se nas folhas e no caule; quando estes nitratos são consumidos pelo animal, alteram-se os processos metabólicos e ao haver excesso de nitritos e nitratos, há uma acumulação dos mesmos na corrente sanguínea, algo prejudicial. Os nitritos ligam-se à hemoglobina e geram a metahemoglobina, o que reduz a capacidade condutora do oxigênio no sangue, dificultando a chegada do mesmo ao feto, levando à óbito o produto em formação (DUPCHAK, 2005). Os sinais na vaca gestante geralmente são ofegantes, respiração rápida, tremores musculares, pulso fraco e acelerado, fraqueza, que termina com a queda do animal e convulsões terminais. Também se sabe que os nitratos têm um efeito vasodilatador, o que origina uma diminuição da pressão sanguínea, em todo caso a morte possui origem na acumulação de metahemoglobina. As vacas afetadas por esse excesso de nitratos desenvolvem incoordenação e dificuldades na capacidade respiratória que vão seguidas por colapso e morte. O sinal mais claro é que o sangue fica escuro. Sob condições de hipoxia o feto pode morrer ao ser iniciado o trabalho de parto, evento fisiológico de alto consumo de oxigênio pela contração muscular marcada necessária para conseguir a expulsão do produto. O estudo desses compostos podem não parecer importantes na vida corriqueira e laboral do campo, porém quando se aparecem problemas de difícil diagnóstico e tratamento, faz-se necessário um aprofundamento de toda a cadeia alimentar ou de ingestão dos animais, alimentos, bebidas, locais de descanso e dormida etc. Pois bem, o presente comentário norteia o assunto sobre os nitratos e nitritos que nada mais são do que compostos não proteicos e que em sua composição possuem nitrogênio e oxigênio, nitrato NO3- e nitrito NO2-. Diante da fermentação ruminal, o alimento rico em NO3- é reduzido pelo rúmen e se transforma em NO2- um composto altamente tóxico que, após absorvido na corrente sanguínea, causa anóxia por morte celular, sendo prejudicial tanto para o bovino adulto, quanto jovem e ainda mais para o feto em desenvolvimento. A ingestão excessiva desses compostos por meio da água ou das forragens podem ocasionar intoxicações. As forragens podem acumular nitrogênio através da fertilização do solo ou da planta com compostos ricos em N, são exemplos de plantas que acumulam bastante nitrato a Braquiária radicans e todas as plantas do gênero Amaranthus spp., para que se diminua o teor de nitratos presentes na forragem o mais indicado é o processo de ensilagem. Ainda relacionada a alimentação, vale ressaltar para o produtor rural que altos teores de nitrato ou nitrito no corpo animal ocasiona a deficiência da vitamina A que é essencial para o mecanismo fisiológico e metabólico do animal. As tabelas 1 e 2 trazem as concentrações ou os níveis ideais e máximos de nitrato presente nas forragens e na água, e se os teores expressos são recomendáveis ou não para a administração aos animais. Vale notar que os nitratos são compostos que se apresentam juntamente com o potássio K, o sódio Na e o próprio nitrogênio N na forma de nitrato e nitrito presente na água ou na matéria seca dos alimentos. Tabela 1: Concentrações de nitrato e recomendações quando apresentados na forma de nitrato de potássio KNO, nitrato de sódio NaNO, e N em forma de nitrato e nitrito na MS dos alimentos Forma de nitrato reportado Recomendações NO3-N NO3- KNO3- NaNO3- —————— 0 – 0,15% 0 – 0,65% 0 – 1% 0 – 0,9% Seguro para os ruminantes, pode utilizar 0,15 – 0,45% 0,65 – 2% 1 – 3% 0,9 – 2,7% Misturar com outros alimentos, compondo no máximo 50% da mistura > 0,45% > 2% > 3% > 2,7% Aumenta o nível de intoxicação, o mais indicado é não usar Fonte: BERCHIELLI et al., 2006. Tabela 2: Concentrações de NO3- e recomendações sobre os níveis de nitrato presente na água para bovinos Conteúdo de NO3- ppm Conteúdo de NO3-N ppm Recomendação 0 - 44 10 Pode utilizar 45 - 132 10 - 20 É seguro se o alimento tiver pouco nitrato e uma dieta balanceada 133 - 220 20 - 46 Prejudicial se for usada por muito tempo 220 – 660 40 – 100 Pode haver perdas e é um risco para vacas leiteiras 660 – 800 100 – 200 Aumenta a possibilidade de perdas, não é indicado usar > 800 > 200 Não utilizar Fonte: TEIXEIRA, 1997. Todas essas informações podem não parecer importantes para a prática no campo, porém em situações de problemas relacionados a altos índices de fetos que nascem mortos tais tabelas podem ser de extrema importância e salvar vidas. No caso de intoxicações, o indicado é o tratamento por azul de metileno a 1% sob dosagem de 4 – 14 mg/kg de peso vivo do animal. Todos esses manejos podem salvar o feto, o que faz com que o mesmo nasça vivo e torne-se um animal produtivo para a propriedade. 15.2 Minerais A deficiência de cobre, também tem sido apontada como uma das possíveis causas de origem de natimortos, uma vez que o cobre está ligado à albumina no sangue e no fígado está ligado à aminoácidos. Sua deficiência gera anemia já que o mesmo está envolvido no metabolismo do ferro, necessário para a formação da hemoglobina. Na deficiência, muda-se a cor da pelagem e da pele devido a necessidade do cobre no mecanismo de síntese da polifenil oxidase, que transforma a tironina em melanina; a escassez altera também a enzima lisil oxidase, necessária na formação das cadeias polipeptídicas de colágeno, por onde surgem os problemas ósseos e articulares (DE ROSA & MATIOLLI, 2002). Altera-se também a atividade do citocromo oxidase que está envolvido na síntese dos fosfolipídios, que formam a camada de mielina necessária para a transmissão nervosa e a resposta motora, causando ataxia e problemas de necrose graves que ocasionam a morte do feto. Além disso, as concentrações de dopamina e noradrenalina são alteradas, afetando o endotélio vascular, resultando adicionalmente em problemas cardiovasculares com graves crises hemolíticas que também causam a morte do produto. Geralmente, diz-se que a soma de todos estes problemas conformam os fatores desencadeadores de morte súbita do feto. Quando há uma deficiência nutricional de cobre, o animal começa a usar seus depósitos hepáticos, se os depósitos se esgotam, evidencia-se uma diminuição nos níveis sanguíneos e aparece a hipocupremia e hipocuprose; depois dos sinais acima mencionados, ocorre a degeneração progressiva do miocárdio, o que também contribui para a morte súbita do feto. O excesso de molibdênio gera uma deficiência de cobre e este também está inter-relacionado com o zinco. Para que não haja dominância de um e deficiência de outro sempre deve-se frisar as quantidades exigidas dos minerais pelos bovinos. O Cu é um elemento essencial e sua disponibilidade deve ser de 10 – 18 mg/kg de MS. O Mo deve ser fornecido em quantidades que não ultrapassem os 15 – 20 mg/kg de MS, a relação entre o Cu e o Mo não deve ser superior que 20, um excesso de Mo causa deficiência de Cu induzida. Por fim, o Zn deve ser fornecido em quantidades que não ultrapassem os 21 – 73 mg/kg de MS. 15.3 Vitaminas A vitamina A é necessária para manter a integridade dos epitélios digestivo, respiratório, genito-urinário e ocular, além disso é fundamental para o desenvolvimento ósseo já que controla a atividade dos osteoclastos e osteoblastos, também assegura a manutenção da permeabilidade das membranas celulares e da pressão do líquido cefalorraquidiano, portanto a sua deficiência provoca queratinização dos tecidos epiteliais, problemas gastrointestinais, o que acaba complicando-se com a invasão de germes e doenças infecciosas. Sua escassez ou falta também ocasionam malformações ósseas e problemas nervosos como ataxia e falhas na contratilidade do miométrio, o que, por fim, resulta na morte do vitelo. Na avitaminose A, as células epiteliais são achatadas e apresentam menor resistência à infecção, pode-se dar que todos os canais glandulares se bloqueiem causando atrofia glandular e morte do bezerro por não poder realizar suas funções fisiológicas. Os betacarotenos das forragens são as fontes mais importantes de vitamina A. A vitamina A deve estar intrinsecamente presente na dieta dos animais em quantidades de 50.000 – 125.000 UI/dia. 15.4 fito-toxicidade O excesso de fitoestrogênios produzidos por leguminosas como o trevo vermelho, trevo subterrâneo, feijão de soja, etc., que possuem estrogênios vegetais semelhantes aos 17β-estradiol que interagem com os receptores nucleares desta hormona e influenciam sobre os seus processos endócrinos. Ocorre estrogenismo que gera infertilidade, já que se limita a liberação de LH e no animal gestante aumenta a contractilidade uterina gerando abortos ou natimortos. Entre os fitoestrógenos estão as isoflavonas, que sofrem algum tipo de transformação no rúmen, onde o Isoflavonoide formononetina se converte em equol enquanto as demais se degradam a produtos inativos. A progesterona é a hormona responsável por manter as condições ideais para a gestação, aumentando-se os níveis de estrogênios ocorrerá a inibição da progesterona e apresentam-se condições adversas para o desenvolvimento e/ou vida do feto. Para se livrar desse problema o mais indicado é a utilização de forragens que além de suprir as necessidades nutricionais dos animais sejam de boa qualidade e utilizadas o mais fresco possível.

Nanotechnology, as with many technologies before it, places a strain on existing legislation and poses a challenge to all administrative agencies tasked with regulating technology-based products. It is easy to see how statutory schemes become outdated, as our ability to understand and affect the world progresses. In this article, we address the regulatory problems that nanotechnology posses for the Food and Drug Administration’s (FDA) classification structure for ‘‘drugs’’ and ‘‘devices.’’ The last major modification to these terms was in 1976, with (...) the enactment of the Medical Device Amendments. There are serious practical differences for a classification as a drug or device in terms of time to market and research. Drugs are classified, primarily, as acting by ‘‘chemical action.’’ We lay out some legal, philosophic, and scientific tools that serve to provide a useful, as well as legally and scientifically faithful, distinction between drugs and devices for the purpose of regulatory classification. These issues we raise are worth the consideration of anyone who is interested in the regulation of nano-products or other novel technologies. (shrink)

Safe-by-Design (SBD) frameworks for the development of emerging technologies have become an ever more popular means by which scholars argue that transformative emerging technologies can safely incorporate human values. One such popular SBD methodology is called Value Sensitive Design (VSD). A central tenet of this design methodology is to investigate stakeholder values and design those values into technologies during early stage research and development (R&D). To accomplish this, the VSD framework mandates that designers consult the philosophical and ethical literature to (...) best determine how to weigh moral trade-offs. However, the VSD framework also concedes the universalism of moral values, particularly the values of freedom, autonomy, equality trust and privacy justice. This paper argues that the VSD methodology, particularly applied to nano-bio-info-cogno (NBIC) technologies, has an insufficient grounding for the determination of moral values. As such, an exploration of the value-investigations of VSD are deconstructed to illustrate both its strengths and weaknesses. This paper also provides possible modalities for the strengthening of the VSD methodology, particularly through the application of moral imagination and how moral imagination exceed the boundaries of moral intuitions in the development of novel technologies.

Philosophers have recently argued, against a prevailing orthodoxy, that standards of knowledge partly depend on a subject’s interests; the more is at stake for the subject, the less she is in a position to know. This view, which is dubbed “Pragmatic Encroachment” has historical and conceptual connections to arguments in philosophy of science against the received model of science as value free. I bring the two debates together. I argue that Pragmatic Encroachment and the model of value-laden (...) class='Hi'>science reinforce each other. Drawing on Douglas’ argument about the indispensability of value judgments in science, and psychological evidence about people’s inability to objectively reason about what they care about, I introduce a novel argument for Pragmatic Encroachment.

A short position paper on how we can preemptively anticipate and design nanotechnology-safe futures.

Martine Nida-Rümelin (1996) argues that color science indicates behaviorally undetectable spectrum inversion is possible and raises this possibility as an objection to functionalist accounts of visual states of color. I show that her argument does not rest solely on color science, but also on a philosophically controversial assumption, namely, that visual states of color supervene on physiological states. However, this assumption, on the part of philosophers or vision scientists, has the effect of simply ruling out certain versions of (...) functionalism. While Nida-Rümelin is quite right to search for empirical tests for claims about the nature of visual states, philosophical issues remain pivotal in determining the correctness of these claims.

In this study, we aimed to investigate how prospective science teachers, who participated in a series of explicit-reflective activities for NOS teaching, understood "science in a social and cultural context" in the context of a biographical documentary film. We adopted a phenomenological approach. The data were analyzed descriptively by considering the aspects of nature of science and the levels of understanding as defined in Dilthey's hermeneutic approach. In this way, we determined participants’ levels of hermeneutic understanding regarding (...) the nature of science. The findings show that the participants regarded science within the framework of aspects of the consensus view blended with somewhat authentic interpretations and at a basic level of understanding from the point of view of hermeneutics. This finding highlights the importance of integrating the hermeneutic approach into the teaching process in understanding science. (shrink)

It is an unfortunate fact of academic life that there is a sharp divide between science and philosophy, with scientists often being openly dismissive of philosophy, and philosophers being equally contemptuous of the naivete ́ of scientists when it comes to the philosophical underpinnings of their own discipline. In this paper I explore the possibility of reducing the distance between the two sides by introducing science students to some interesting philosophical aspects of research in evolutionary biology, using biological (...) theories of the origin of religion as an example. I show that philosophy is both a discipline in its own right as well as one that has interesting implications for the understanding and practice of science. While the goal is certainly not to turn science students into philoso- phers, the idea is that both disciplines cannot but benefit from a mutual dialogue that starts as soon as possible, in the classroom.

Increasingly, in data-intensive areas of the life sciences, experimental results are being described in algorithmically useful ways with the help of ontologies. Such ontologies are authored and maintained by scientists to support the retrieval, integration and analysis of their data. The proposition to be defended here is that ontologies of this type – the Gene Ontology (GO) being the most conspicuous example – are a part of science. Initial evidence for the truth of this proposition (which some will find (...) self-evident) is the increasing recognition of the importance of empirically-based methods of evaluation to the ontology development work being undertaken in support of scientific research. The ontologies created by scientists must, of course, be associated with implementations satisfying the requirements of software engineering. But these ontologies are not themselves engineering artifacts, and to conceive them as such brings grievous consequences. Rather, we shall argue, ontologies such as the GO are comparable to scientific theories, to scientific databases, or to scientific journal publications. Such a view implies a radically new conception of what is involved in the authoring, maintenance and application of ontologies in scientific contexts, and therewith also a radically new approach to the evaluation of ontologies and to the training of ontologists.

The cultural transmission of theological concepts remains an underexplored topic in the cognitive science of religion (CSR). In this paper, I examine whether approaches from CSR, especially the study of content biases in the transmission of beliefs, can help explain the cultural success of some theological concepts. This approach reveals that there is more continuity between theological beliefs and ordinary religious beliefs than CSR authors have hitherto recognized: the cultural transmission of theological concepts is influenced by content biases that (...) also underlie the reception of ordinary religious concepts.

A principle, according to which any scientific theory can be mathematized, is investigated. Social science, liberal arts, history, and philosophy are meant first of all. That kind of theory is presupposed to be a consistent text, which can be exhaustedly represented by a certain mathematical structure constructively. In thus used, the term “theory” includes all hypotheses as yet unconfirmed as already rejected. The investigation of the sketch of a possible proof of the principle demonstrates that it should be accepted (...) rather a metamathematical axiom about the relation of mathematics and reality. The main statement is formulated as follows: Any scientific theory admits isomorphism to some mathematical structure in a way constructive. Its investigation needs philosophical means. Husserl’s phenomenology is what is used, and then the conception of “bracketing reality” is modelled to generalize Peano arithmetic in its relation to set theory in the foundation of mathematics. The obtained model is equivalent to the generalization of Peano arithmetic by means of replacing the axiom of induction with that of transfinite induction. The sketch of the proof is organized in five steps: a generalization of epoché; involving transfinite induction in the transition between Peano arithmetic and set theory; discussing the finiteness of Peano arithmetic; applying transfinite induction to Peano arithmetic; discussing an arithmetical model of reality. Accepting or rejecting the principle, two kinds of mathematics appear differing from each other by its relation to reality. Accepting the principle, mathematics has to include reality within itself in a kind of Pythagoreanism. These two kinds are called in paper correspondingly Hilbert mathematics and Gödel mathematics. The sketch of the proof of the principle demonstrates that the generalization of Peano arithmetic as above can be interpreted as a model of Hilbert mathematics into Gödel mathematics therefore showing that the former is not less consistent than the latter, and the principle is an independent axiom. The present paper follows a pathway grounded on Husserl’s phenomenology and “bracketing reality” to achieve the generalized arithmetic necessary for the principle to be founded in alternative ontology, in which there is no reality external to mathematics: reality is included within mathematics. That latter mathematics is able to self-found itself and can be called Hilbert mathematics in honour of Hilbert’s program for self-founding mathematics on the base of arithmetic. The principle of universal mathematizability is consistent to Hilbert mathematics, but not to Gödel mathematics. Consequently, its validity or rejection would resolve the problem which mathematics refers to our being; and vice versa: the choice between them for different reasons would confirm or refuse the principle as to the being. An information interpretation of Hilbert mathematics is involved. It is a kind of ontology of information. The Schrödinger equation in quantum mechanics is involved to illustrate that ontology. Thus the problem which of the two mathematics is more relevant to our being is discussed again in a new way A few directions for future work can be: a rigorous formal proof of the principle as an independent axiom; the further development of information ontology consistent to both kinds of mathematics, but much more natural for Hilbert mathematics; the development of the information interpretation of quantum mechanics as a mathematical one for information ontology and thus Hilbert mathematics; the description of consciousness in terms of information ontology.

A survey of color science and color vision.

Open science will make science more efficient, reliable, and responsive to societal challenges. The European Commission has sought to advance open science policy from its inception in a holistic and integrated way, covering all aspects of the research cycle from scientific discovery and review to sharing knowledge, publishing, and outreach. We present the steps taken with a forward-looking perspective on the challenges laying ahead, in particular the necessary change of the rewards and incentives system for researchers (for (...) which various actors are co-responsible and which goes beyond the mandate of the European Commission). Finally, we discuss the role of artificial intelligence (AI) within an open science perspective. (shrink)

Oswald Spengler is best known as a philosopher of history. However, one can trace in volume one of his The Decline of the West a sustained consideration of philosophical issues pertaining to the nature and practice of science that I suggest can be considered to be a philosophy of science. Not only has Spengler’s philosophy of science been largely overlooked, so too has its peculiar fictionalist character. By elaborating on the fictionalist character of Spengler’s scientific views I (...) shall consider his work in comparison with that of Hans Vaihinger, a contemporary of Spengler and noted fictionalist with regards to science. This comparison not only supports my interpretation of Spengler’s philosophy of science as fictionalist, it also throws into relief the numerous affinities between the thought of two philosophers who are not usually associated, in particular with regards to their accounts of the origins of science in the structures of human consciousness. This fictionalist affinity in turn suggests the need for a wholesale reappraisal of Spengler’s philosophical outlook. (shrink)

In the growing Prussian university system of the early nineteenth century, "Wissenschaft" (science) was seen as an endeavor common to university faculties, characterized by a rigorous methodology. On this view, history and jurisprudence are sciences, as much as is physics. Nineteenth century trends challenged this view: the increasing influence of materialist and positivist philosophies, profound changes in the relationships between university faculties, and the defense of Kant's classification of the sciences by neo-Kantians. Wilhelm Dilthey's defense of the independence of (...) the methodology of the human sciences (Geisteswissenschaften) from those of the natural sciences (Naturwissenschaften) is as much a return to the ideal of Wissenschaft as a cooperative endeavor as it is a defense of the autonomy of interpretive or hermeneutic methods. The debate between Dilthey and the neo-Kantian Wilhelm Windelband at the close of the century illuminates the development of this dialogue over the nineteenth century. (shrink)

The shape of the Earth's surface, its topography, is a fundamental dimension of the environment, shaping or mediating many other environmental flows or functions. But there is a major divergence in the way that topography is conceptualized in different domains. Topographic cartographers, information scientists, geomorphologists and environmental modelers typically conceptualize topographic variability as a continuous field of elevations or as some discrete approximation to such a field. Pilots, explorers, anthropologists, ecologists, hikers, and archeologists, on the other hand, typically conceptualize this (...) same variability in terms of hills and valleys, mountains and plains, barrows and trenches, that is, as (special sorts of) objects, with locations, shapes, and often names of their own.

This paper explores whether it is possible to reformulate or re-interpret Lewis’s theory of fundamental laws of nature—his “best system analysis”—in such a way that it becomes a useful theory for special science laws. One major step in this enterprise is to make plausible how law candidates within best system competitions can tolerate exceptions—this is crucial because we expect special science laws to be so called “ceteris paribus laws ”. I attempt to show how this is possible and (...) also how we can thereby make the first step towards a solution for the infamous difficulties surrounding the troublesome ceteris paribus clause. The paper outlines the general ideas of the theory but also points out some of its difficulties and background assumptions. (shrink)

The empirical study of belief is emerging at a rapid clip, uniting work from all corners of cognitive science. Reliance on belief in understanding and predicting behavior is widespread. Examples can be found, inter alia, in the placebo, attribution theory, theory of mind, and comparative psychological literatures. Research on belief also provides evidence for robust generalizations, including about how we fix, store, and change our beliefs. Evidence supports the existence of a Spinozan system of belief fixation: one that is (...) automatic and independent of belief rejection. Independent research supports the existence of a system of fragmented belief storage: one that relies on large numbers of causally isolated, context-sensitive stores of belief in memory. Finally, empirical and observational data support at least two systems of belief change. One system adheres, mostly, to epistemological norms of updating; the other, the psychological immune system, functions to guard our most centrally held beliefs from potential inconsistency with newly formed beliefs. Refining our under- standing of these systems can shed light on pressing real-world issues, such as how fake news, propaganda, and brainwashing exploit our psychology of belief, and how best to construct our modern informational world.

Science and religion are based on different aspects of human experience. Science is a way of knowing and understanding the natural world, using empirical evidence and testable explanations. Religious faith does not depend only on empirical evidence and typically involves supernatural forces or entities. Thus, science and religion are separate and address the aspects of human understanding in different ways. The dialogue between science and religion is productive from a theological point of view since the world-environment (...) in which the theologians live is most productively studied by the sciences. The Sikh teachings, as recorded in Sri Guru Granth Sahib (SGGS), not only recognize a relationship between religion and science, logic and culture, it describes them to be interdependent. Sikh doctrines enunciate that the pursuits of learning about the cosmos by science and religion are not confrontational but complementary. Sikh precepts stress that the key to creating syncretism between science and religion is to cultivate a spirit of humility among scientists, theologians, faith practitioners, and clerics in front of Infinite Wisdom (Creator).

What is the relation between science and ideology? Are they incompatible, complementary or the same thing? Should science avoid “contamination” from ideology? Is there an only way to do science? Does anyone of them lead to the same results and give us the same worldview? We will focus on the figure of Alexander Bogdanov, Russian physician and philosopher, in order to discuss these and other relevant topics. His theories gave birth to what may be called later “the (...) theory of two sciences”, which entitles this work. (shrink)

Pourquoi accorder un rôle essentiel à la délibération publique dans le choix des normes éthiques et politiques guidant les sciences? À partir d’un débat récent en économie du bien-être, cet article soutient que l’introduction de normes éthiques et politiques en sciences doit respecter le principe de neutralité procédurale, et qu’une délibération publique bien encadrée respecte ce principe. Je présenterai deux raisons de croire que les sciences doivent respecter la neutralité procédurale. Le premier argument est lié au rôle que devrait jouer (...) l’examen libre et critique dans le développement des sciences. Le second argument repose sur l’idée que les sciences devraient être sensibles aux procédures présentant le meilleur potentiel épistémique. Pour ces deux raisons, si elle prend position en faveur d’idéaux normatifs, l’économie du bien-être devrait se tourner vers une approche délibérative, rationnelle et impartiale pour y parvenir.

Feminism science is a science that makes women both the subject and the object of research. This study aims to reveal the social processes of the formation of feminism science. This research uses qualitative research methods with scientific theory study techniques, and uses the sociology of knowledge as an analytical approach. The result of this research is that the social process of the formation of feminism science takes place in three momentums, namely, externalization and objectification in (...) which feminist movements and thoughts emerge in three phases which provide the foundation for the formation of feminism science in its internalization momentum.

When scientists or science reporters communicate research results to the public, this often involves ethical and epistemic risks. One such risk arises when scientific claims cause cognitive or behavioural changes in the audience that contribute to the self-fulfilment of these claims. I argue that the ethical and epistemic problems that such self-fulfilment effects may pose are much broader and more common than hitherto appreciated. Moreover, these problems are often due to a specific psychological phenomenon that has been neglected in (...) the research on science communication: many people tend to conform to ‘descriptive norms’, that is, norms capturing (perceptions of) what others commonly do, think, or feel. Because of this tendency, science communication may frequently produce significant social harm. I contend that scientists have a responsibility to assess the risk of this potential harm and consider adopting strategies to mitigate it. I introduce one such strategy and argue that its implementation is independently well motivated by the fact that it helps improve scientific accuracy. (shrink)

Although the main focus of Hume’s career was in the humanities, his work also has an observable role in the historical development of natural sciences after his time. To show this, I shall center on the relation between Hume and two major figures in the history of the natural sciences: Charles Darwin (1809–1882) and Albert Einstein (1879–1955). Both of these scientists read Hume. They also found parts of Hume’s work useful to their sciences. Inquiring into the relations between Hume and (...) the two scientists shows that his philosophical positions had a partial but constructive role in the formation of modern biology and physics. This is accordingly a clear indication of Hume’s impact on the scientific tradition. Before proceeding to analyze Hume’s contribution to the history of science, it is important to address his broader role in the history of philosophy of science. Hume’s discussions concerning the topics of causation, induction, the distinction between mathematical and empirical propositions, and laws of nature have been important for the philosophy of science of the nineteenth and twentieth centuries.

Drawing on the SAGE minutes and other documents, I consider the wider lessons for norms of scientific advising that can be learned from the UK’s initial response to coronavirus in the period January-March 2020, when an initial strategy that planned to avoid total suppression of transmission was abruptly replaced by an aggressive suppression strategy. I introduce a distinction between “normatively light advice”, in which no specific policy option is recommended, and “normatively heavy advice” that does make an explicit recommendation. I (...) argue that, although scientific advisers should avoid normatively heavy advice in normal times in order to facilitate democratic accountability, this norm can be permissibly overridden in situations of grave emergency. SAGE’s major mistake in early 2020 was not that of endorsing a particular strategy, nor that of being insufficiently precautionary, but that of relying too heavily on a specific set of “reasonable worst-case” planning assumptions. I formulate some proposals that assign a more circumscribed role to “worst-case” thinking in emergency planning. In an epilogue, I consider what the implications of my proposals would have been for the UK’s response to the “second wave” of late 2020. (shrink)

On Nietzsche, science, the oral tradition -- or the troubadours and ancient Greek music drama.

The development of modern science has depended strongly on specific features of the cultures involved; however, its results are widely and trans-culturally accepted and applied. The science and technology of electricity provides a particularly interesting example. It emerged as a specific product of post-Renaissance Europe, rooted in the Greek philosophical tradition that encourages explanations of nature in theoretical terms. It did not evolve in China presumably because such encouragement was missing. The trans-cultural acceptance of modern science and (...) technology is postulated to be due, in part, to the common biological dispositions underlying human cognition, with generalizable capabilities of abstract, symbolic and strategic thought. These faculties of the human mind are main prerequisites for dynamic cultural development and differentiation. They appear to have evolved up to a stage of hunters and gatherers perhaps some 100 000 years ago. However, the extent of the correspondence between some constructions of the human mind and the order of nature, as revealed by science, is a late insight of the last centuries. Quantum physics and relativity are particularly impressive examples. (shrink)

Debates over the reality of race often rely on arguments about the connection between race and science—those who deny that race is real argue that there is no significant support from science for our ordinary race concepts; those who affirm that race is real argue that our ordinary race concepts are supported by scientific findings. However, there is arguably a more fundamental concern here: How should we define race concepts in the first place? The reason I claim that (...) this definitional question is more fundamental is that our handling of the underlying definitional problem often determines the scientific support our ordinary race concepts need, and importantly the likelihood of finding such support. In short, the defini- tional question, “How do we define race?” often undercuts the question of whether race is scientifically meaningful. (shrink)

In the last decade Open Science principles, such as Open Access, study preregistration, use of preprints, making available data and code, and open peer review, have been successfully advocated for and are being slowly adopted in many different research communities. In response to the COVID-19 pandemic many publishers and researchers have sped up their adoption of some of these Open Science practices, sometimes embracing them fully and sometimes partially or in a sub-optimal manner. In this article, we express (...) concerns about the violation of some of the Open Science principles and its potential impact on the quality of research output. We provide evidence of the misuses of these principles at different stages of the scientific process. We call for a wider adoption of Open Science practices in the hope that this work will encourage a broader endorsement of Open Science principles and serve as a reminder that science should always be a rigorous process, reliable and transparent, especially in the context of a pandemic where research findings are being translated into practice even more rapidly.

There is a correlation between positions taken on some scientific questions and political leaning. One way to explain this correlation is the cultural cognition hypothesis (CCH): people's political leanings are causing them to process evidence to maintain fixed answers to the questions, rather than to seek the truth. Another way is the different background belief hypothesis (DBBH): people of different political leanings have different background beliefs which rationalize different positions on these scientific questions. In this article, I argue for two (...) things. I argue that two attempts by proponents of the CCH to discredit the DBBH fail. And I argue that this matters, because while the CCH makes epistemic paternalistic interventions seem called for (as some philosophers have argued compellingly), the DBBH does not. The DBBH makes it much easier to stay closer to an ideal of deliberative democracy. (shrink)

Weber's 'science as a vocation' has often been viewed as a therapeutic concept with no functional significance in the fully bureaucratized and professionalized modern science. However, development in the philosophy of science in the last century, especially the Kuhn thesis of the discontinuity of scientific progress and the Duhem-Quine thesis of underdetermination, shows that Weber's distinction between science as a vocation and science as a profession (career) can potentially answer one of the oldest questions in (...) science studies: What makes scientific breakthroughs possible?

In a world of ever growing specialization, the idea of a unity of science is commonly discarded, but cooperative work involving cross-disciplinary points of view is encouraged. The aim of this paper is to show with some textual support that Charles S. Peirce not only identified this paradoxical situation a century ago, but he also mapped out some paths for reaching a successful solution. A particular attention is paid to Peirce's classification of the sciences and to his conception of (...) science as a collective and cooperative activity of all those whose lives are animated by the desire to discover the truth. -/- .

This short paper, written for a wide audience, introduces "science and values" topics as they have arisen in the context of eugenics. The paper especially focuses on the context of 20th century eugenics in western Canada, where eugenic legislation in two provinces was not repealed until the 1970s and thousands of people were sterilized without their consent. A framework for understanding science-value relationships within this context is discussed, and so too is recent relevant work in philosophy of (...) class='Hi'>science. (shrink)

This review article discusses the book Understanding How Science Explains the World by Kevin McCain, published by Cambridge University Press (2022). With an impressive combination of clarity and depth, McCain provides the reader with a firm grasp of how science works, of what science aims to achieve, and of what makes science a successful epistemic enterprise. The review article reconstructs the book’s overall dialectic and identifies one potential point of tension which concerns the role of truth (...) or accuracy in scientific knowledge. -/- . (shrink)

Science is founded on a method based on critical thinking. A prerequisite for this is not only a sufficient command of language but also the comprehension of the basic concepts underlying our understanding of reality. This constraint implies an awareness of the fact that the truth of the World is not directly accessible to us, but can only be glimpsed through the construction of mod- els designed to anticipate its behaviour. Because the relationship between models and reality rests on (...) the interpretation of founding postulates and in- stantiations of their predictions (and is therefore deeply rooted in language and culture), there can be no demarcation between science and non-science. However, critical thinking is essential to ensure that the link between models and reality is gradually made more adequate to reality, based on what has already been established, thus guaranteeing that science progresses on this basis and excluding any form of relativism.

The chapter discusses two points of intersection between the communication of science-based information about risk and philosophical ethics. The first is a logically unnecessary bias toward consequentialist ethics, and a corresponding tendency to overlook the significance of deontological and virtue based ways to interpret the findings of a scientific risk analysis. The second is a grammatical bias that puts scientific communicators at odds with the expectations of a non-scientific audience.

How can we think about things in the outside world? There is still no widely accepted theory of how mental representations get their meaning. In light of pioneering research, Nicholas Shea develops a naturalistic account of the nature of mental representation with a firm focus on the subpersonal representations that pervade the cognitive sciences.

Unity of science was once a very popular idea among both philosophers and scientists. But it has fallen out of fashion, largely because of its association with reductionism and the challenge from multiple realisation. Pluralism and the disunity of science are the new norm, and higher-level natural kinds and special science laws are considered to have an important role in scientific practice. What kind of reductionism does multiple realisability challenge? What does it take to reduce one phenomenon (...) to another? How do we determine which kinds are natural? What is the ontological basis of unity? In this Element, Tuomas Tahko examines these questions from a contemporary perspective, after a historical overview. The upshot is that there is still value in the idea of a unity of science. We can combine a modest sense of unity with pluralism and give an ontological analysis of unity in terms of natural kind monism. This title is available as Open Access on Cambridge Core. (shrink)

Credences are similar to levels of confidence, represented as a value on the [0,1] interval. This chapter sheds light on questions about credence, including its relationship to full belief, with an eye toward the empirical relevance of credence. First, I’ll provide a brief epistemological history of credence and lay out some of the main theories of the nature of credence. Then, I’ll provide an overview of the main views on how credences relate to full beliefs. Finally, I’ll turn to the (...) empirical, and suggest some ways that cognitive science does and could answer questions about credence, such as what credences one has, how credences relate to beliefs, and the extent to which we can control our credences.

Neurath’s scientific utopianism is the proposal that the social sciences should engage in the elaboration, development, and comparison of counterfactual scenarios, the ‘utopias’. Such scenarios can be understood as centerpieces of scientific thought experiments, that is, in exercises of imagination that not only promote conceptual revision, but also stimulate creativity to deal with experienced problems, as utopias are efforts to imagine what the future could look like. Moreover, utopian thought experiments can offer scientific knowledge to inform political debates and decisions, (...) contributing to the shaping of society. This essay reconstructs a historical event as an example of Neurath’s utopianist methodology. In the late 1970s and early 1980s, a scientific and political commission appointed by the Western German Parliament devised and compared four scenarios for future energetic-economic policies. Conclusions of the commission informed political decisions that put Western (later reunified) Germany in a route towards becoming a green industrial power. A fundamental part of the commission’s work involved an appeal to imagination, allowing for the characterization under Neurath’s methodology. (shrink)

Science was not far from philosophy in ancient thought, but the two were one thing. I do not know whether the ancient philosophers considered themselves the issue of the relationship between them, as the modern and contemporary philosophers did. But the sure thing is that the natural sciences became independent from philosophy in the modern era, and most of the scientific departments in universities were divided into two parts: sciences, literature, and humanities. At the end of the nineteenth century (...) and what followed, there were attempts to link them. Charles Peirce wrote on the scientific method and scientific metaphysics. The Vienna Circle presented a scientific conception of the world and the logical empiricists and Popper was concerned with the problem of distinguishing science from pseudoscience. The logical empiricists provided the criterion of verifiability, and Popper proposed the falsification principle. Quine defended a natural epistemology that asserts that philosophy is part of natural science. Bunge offered his own criteria for distinguishing science in the context of scientific philosophy. In this article, I want to refute the claim that philosophy has died and that science does not need it. I proved that the notion that philosophy is useless to science is not only wrong but also harmful to society, education, and science itself. This comes in a broader context, which is the moderate scientific tendency that I have defended in some of my writings. -/- لم يكن العلم بعيدًا عن الفلسفة في الفكر القديم، بل كان الاثنان شيئًا واحدًا. ولست أدرى أكان الفلاسفة القدماء يلقون على أنفسهم مسألة العلاقة بينهما مثل ما ألقاها الفلاسفة المحدثون والمعاصرون أم لا. ولكن الشيء المحقق أن العلوم الطبيعية استقلت عن الفلسفة في العصر الحديث، وانقسمت معظم الأقسام العلمية في الجامعات إلى قسمين: العلوم، والآداب والإنسانيات. وظهرت في أواخر القرن التاسع عشر وما تلاه محاولات لربطهما. كتب تشارلز بيرس عن المنهج العلمي والميتافيزيقا العلمية. وقدمت جماعة فيينا تصورًا علميًّا للعالم، واهتم التجريبيون المنطقيون وبوبر بمشكلة تمييز العلم من العلم الزائف؛ قدم التجريبيون المنطقيون معيار القابلية للتحقق، واقترح بوبر مبدأ التكذيب. ودافع كواين عن إبستمولوجيا طبيعية تؤكد أن الفلسفة جزء من العلم الطبيعي. وقدم بونجي معاييره الخاصة لتمييز العلم في سياق الفلسفة العلمية.

I first quickly outline what I think grasping is, and suggest that it is both among our basic aims of inquiry and not essentially tied to belief, justification, or knowledge. Then, I briefly look at some places in the metaphysics of science in which it looks like our aim of grasping and our aim in knowing—or perhaps more specifically in knowing the explanations for things—might seem to conflict. I will use this conflict to support a broader view: sometimes, we (...) might develop philosophical views or theories—and even endorse them—in order to better grasp them, regardless of whether we genuinely believe them, or are justified in so doing. At other times, we may be aiming at propositional knowledge. These aims can come apart, and perhaps even systematically come apart. A pluralism about the value of those aims doesn’t entail an “anything goes” attitude with respect to how we think about what philosophical views to put forward, defend, or endorse, however—far from it. Instead, it suggests that what counts as a virtue of a philosophical theory depends on our aims in espousing it. If philosophers have distinct aims at the meta-level, it will be hard for them to engage in joint theory evaluation at the first-order level. At least all three of theoretical virtues, evaluative judgments of philosophical views, and what attitudes we ought to have towards the views we ourselves espouse will vary according to our guiding metaphilosophical aims.
