In the introduction to his famous book, La Science et l’hypothèse, Poincaré remarks on the necessary role and legitimacy of hypotheses. He establishes a triple classification of hypotheses, dividing them into verifiable, useful, and apparent. However, in chapter 9, entitled ‘Les hypothèses en physique’, he gives a slightly different triadic classification: natural hypotheses, indifferent hypotheses, and real generalizations. The origin of this second classification is a lecture given at the International Congress of Physics, Paris, 1900. What are the similarities and (...) differences between these two classifications? My main purpose is to provide a possible equivalence between the two classifications in order to clarify the role of hypotheses in Poincaré’s epistemology of natural science. The discussion will be based on the two fundamental texts mentioned above and on the contrast between Poincaré’s use of the notion of hypothesis and that of some of his contemporaries. (shrink)

This paper aims at understanding the concept of convention in mechanics as a notion transferred from the field of jurisprudence. This enables us to clarify it as a new epistemic category having a pertinent role in the transformation of mechanics in the nineteenth century. Such understanding permits a separation from linguistic and arbitrary conventions, thus highlighting its epistemic features and not transforming fundamental principles into mere arbitrary agreements. After addressing the main references in the literature discussing the role of convention (...) in mechanics, we analyze its classical use as a concept originating from law. Then we explain its use by Carl G. Jacobi, Ferdinand F. Reech, and J. Henri Poincaré. Here we also show how their uses conform to the features analyzed regarding conventions in jurisprudence. Finally, we try to explain how the use of this concept, among other factors, contributed to the transformation of mechanics. (shrink)

The aim of this paper is to argue that there existed relevant interactions between mechanics and geometry during the first half of the nineteenth century, following a path that goes from Gauss to Riemann through Jacobi. By presenting a rich historical context we hope to throw light on the philosophical change of epistemological categories applied by these authors to the fundamental principles of both disciplines. We intend to show that presentations of the changing status of the principles of mechanics as (...) a mere epiphenomenon of the emergence of non-Euclidean geometries are inaccurate, that the relations between the two disciplines were richer than what is usually considered in the literature. These claims will be based on historical and philosophical arguments, starting from the fact that disciplinary boundaries at the time were not rigid as we are used today. It is widely known that the main figures we target worked in different areas, which is a first piece of evidence for the plausibility of our main thesis. (shrink)

Much of the focus on Poincaré’s philosophy of science has been on the notion of convention, a crucial concept that has become distinctive of his position. However, other notions have received much less attention. That is the case of verifiable hypotheses. This kind of hypotheses seems to be constituted from the generalization of several observable facts. So, in order to understand what these hypotheses are, we need to know what a fact to Poincaré is. He divides facts into brute and (...) scientific facts. The characterization of this duality is not trivial at all, and leads us to the following questions that we will discuss in this paper: which the part of construction that exists in a scientific fact and which the part of translation, that is, what remains from the brute fact in the scientific one?; and when we conceive a generalized hypothesis, are we supposed to do it from scientific or from brute facts? The clarification of these questions could lead to distinguish the part of construction and the part of translation in the first steps of science, which is essential to get a better understanding of Poincaré’s conception of science.

Este artículo comenta una conferencia de Louis de Broglie de 1952 en la que se replantea sus ideas iniciales sobre la mecánica cuántica. Defenderemos la tesis de que, en ese trabajo, pese a la referencia al indeterminismo, el objetivo del físico francés es presentar una interpretación causal de esta teoría y no poner de manifiesto su indeterminismo. Así, analizaremos la noción de causalidad que presenta con el objetivo de separarla del determinismo. Estructuraremos la noción presentada por de Broglie en tres (...) partes y la conexión entre las mismas. Para separar causalidad de determinismo utilizaremos una definición no restrictiva de esta noción y presentaremos los problemas que tiene la noción de causalidad utilizada por de Broglie. Finalmente, defenderemos una interpretación de las ideas de de Broglie más como una concepción filosófica que científica y ofreceremos alternativas filosóficas a la misma. (shrink)

Poincaré’s conventionalism has been interpreted in many writings as a philosophical position emerged by reflection on certain scientific problems, such as the applicability of geometry to physical space or the status of certain scientific principles. In this paper I would like to consider conventionalism as a philosophical position that emerged from Poincaré’s scientific practice. But not so much from dealing with scientific problems, as from the use of two specific methodologies proper to modern mathematics and the modern natural sciences: methodological (...) structuralism and the hypothetical-deductive method—thus, as a philosophical position which emerged from a way (or rather, two ways) ofdoingscience. With this approach, I try to deepen the analysis of connections between Poincaré’s scientific practice and his philosophy. (shrink)

Guest Editors’ introduction to the Monographic Section.

This paper discusses the different teaching-learning styles and how they can be applied to university education. It is a common misconception that there are only three learning styles: visual, auditory, and kinesthetic. There are nine different learning styles that can be applied to university teaching-learning. With a literature review, these nine different learning styles and how they can be used in the classroom setting will be explored. In addition, teaching techniques and strategies in a university education will be explored. The (...) importance of these techniques and how they can be improved will also be discussed, considering three different methods: active learning, collaborative learning, and self-directed learning, taking into account the integration of technology in its design. Finally, a dissertation will be made on the new forms of teaching for the training of professionals for industry 4.0 and the new labor demands. (shrink)

The controversy between Euclidean and non-Euclidean geometry arose new philosophical and scientific insights which were relevant to the later development of natural science. Here we want to consider Poincaré and Helmholtz’s positions as two of the most important and original ones who contributed to the subsequent development of the epistemology of natural sciences. Based in these conceptions, we will show that the role of philosophy is still important for some aspects of science.

Muita da literatura sobre a filosofia da ciência de Poincaré tem estado focada na noção de convenção, um conceito crucial que identifica a sua posição. No entanto, há outras noções que têm recebido menos atenção. Este é o caso das hipóteses verificáveis. Este tipo de hipótese parece ser constituído a partir da generalização de vários fatos observáveis. Assim, para compreender o que são estas hipóteses, temos de saber o que é um fato para Poincaré. Ele divide fatos em brutos e (...) científicos. A caracterização desta dualidade não é de tudo trivial, e nos leva às seguintes questões que discutiremos neste artigo: (1) qual a parte de construção que existe num fato científico e qual a parte de tradução? Isto é, o que permanece do fato bruto no fato científico? E (2) quando concebemos uma hipótese generalizada, a generalização é feita a partir dos fatos científicos ou dos fatos brutos? A clarificação destas questões pode levar a distinguir a parte de construção e a parte de tradução desde os primeiros passos da ciência, o que é essencial para conseguir uma melhor compreensão da concepção de ciência de Poincaré.

Pervasive feminism is a component located in emotionality—feminist emotion—and contains women's primary agency. Because affect and emotions are elusive, an interpretive conceptual tool is necessary and is key to making use of their potential for feminist politics aimed at women's empowerment and well-being and to build gender equality. This essay builds on contemporary feminist theory and affect theory and draws from multidisciplinary research. It presents a new theoretical framework anchored in hermeneutics and phenomenology to pin down the affective component of (...) women's multifaceted, intersectional emotional experiences of gender. A case study also illustrates how the theoretical premises around the concept of feminist emotion are compatible with and useful for feminist praxis. (shrink)

The DNase I hypersensitive sites (DHSs) of chromatin constitute one of the best landmarks of eukaryotic genes that are poised and/or activated for transcription. For over 35 years, the high‐mobility group nucleosome‐binding chromosomal proteins HMGN1 and HMGN2 have been shown to play a role in the establishment of these chromatin‐accessible domains at transcriptional regulatory elements, namely promoters and enhancers. The critical presence of HMGNs at enhancers, as highlighted by a recent publication, suggests a role for them in the structural and (...) functional fine‐tuning of the DHSs in vertebrates. As we review here, while preferentially out‐competing histone H1 binding and invading neighbor nucleosomes, HMGNs may also modulate histone H3 at serine 10 (H3S10ph), which plays an important role in enhancer function and transcriptional initiation.

We focus on the literature about UBI and the experiments developed all around the world to test it in order to address how UBI implementation could affect entrepreneurship. Building on these findings and various strands of entrepreneurial theory, we develop a theoretical framework to explain how the implementation of UBI would dramatically change the environment of entrepreneurial activity, shaping entrepreneurial action at three levels: (i) the desirability of becoming an entrepreneur; (ii) the perceived feasibility of becoming an entrepreneur; (iii) the (...) propensity to act. Consequently, UBI implementation would arguably facilitate the decision to become an entrepreneur. The contribution of the paper is threefold. It firstly provides a theoretical framework that opens new directions for further research on the relationship between UBI and entrepreneurship. Secondly, it offers new insights for policy makers by shedding light on potential effects of UBI implementation. Finally, it raises further questions that remains unsolved related to the role of non-pecuniary motivations and financial constraints. (shrink)

This volume presents a selection of papers from the Poincaré Project of the Center for the Philosophy of Science, University of Lisbon, bringing together an international group of scholars with new assessments of Henri Poincaré's philosophy of science-both its historical impact on the foundations of science and mathematics, and its relevance to contemporary philosophical inquiry. The work of Poincaré (1854-1912) extends over many fields within mathematics and mathematical physics. But his scientific work was inseparable from his groundbreaking philosophical reflections, and (...) the scientific ferment in which he participated was inseparable from the philosophical controversies in which he played a pre-eminent part. The subsequent history of the mathematical sciences was profoundly influenced by Poincaré's philosophical analyses of the relations between and among mathematics, logic, and physics, and, more generally, the relations between formal structures and the world of experience. The papers in this collection illuminate Poincaré's place within his own historical context as well as the implications of his work for ours. (shrink)

Mathematical Knowledge and the Interplay of Practices. By Ferreirós José.

Cuando fray Luis de Granada fue invitado por Antonio Pinheiro, obispo abogado de Miranda, a pronunciar un sermón en la ceremonia de su ordenación episcopal, abordó el oficio y las costumbres de los obispos. Posteriormente ese sermón fue ampliado y convertido en un auténtico libro sobre el oficio de pastor de almas.

Posteriormente, será examinada como o sentido de biopolítica na obra “Emdefesa da sociedade” se relaciona com o genocídio do povo negro e (...) pobre. Em seguida, serão analisadas a obra “A Vontade de Saber” e as biopolíticas anti feministas no contexto dessa pandemia. Em quarto lugar, será compreendido o sentido de biopolítica em “Território e População” e sua relação com as estatística s e o isolamento social. Por fim, será abordado o conceito de biopolítica em “Nascimento da biopolítica” e sua relação com agovernamentalidade neoliberal durante a pandemia do coronavírus. (shrink)

In Greek inscriptions on cult foundations and regulations from the Hellenistic period onwards it is possible to see the development of an especial religious discourse that includes ancient and new hymnic elements, in addition to new topoi that do not belong to the Hymn tradition. This new religious discourse develops incorporating new features of Greco-Roman religion, strongly influenced by oriental cults, and at the same time well aware of the new philosophical trends that very much pervaded religion at this time. (...) Some sacred inscriptions from the third century BC onwards show precedents of elements well attested in the sacred literary prose of the second century AD. In this paper, the main topoi that constitute this new religious discourse will be analyzed looking specifically at the topoi concerning the founder of the sacred institution or norms, the god or gods worshipped and the worshippers, and also the topoi concerning the content of the foundation norms and the resources used to force the observance of the norms.

El deseo de modificar artificialmente la conciencia es un hecho tan antiguo como la humanidad pero no es hasta muy recientemente cuando surge el interés científico y social entorno a la relación entre enfermedad mental y drogas. En las últimas décadas esta preocupación se ha avivado vistos los efectos devastadores del consumo de algunas sustancia, la aparición de nuevas drogas y a los avances en la organización del saber en torno a la psicopatología. Entrar a fondo en el tema ser (...) ía largo, supondría exponer las definiciones y límites de los conceptos "enfermedad mental" y "toxicomanía" así como las interacciones entre ambos problemas que dan como resultado complejos entrecruzamientos intercmbios.
