The first half of the twentieth century was marked by the simultaneous development of logic and mathematics. Logic offered the necessary means to justify the foundations of mathematics and to solve the crisis that arose in mathematics in the early twentieth century. In European science in the late nineteenth century, the ideas of symbolic logic, based on the works of J. Bull, S. Jevons and continued by C. Pierce in the United States and E. Schroeder in Germany were getting popular. (...) The works by G. Frege and B. Russell should be considered more progressive towards the development of mathematical logic. The perspective of mathematical logic in solving the crisis of mathematics in Ukraine was noticed by Professor of Mathematics of Novorossiysk University Ivan Vladislavovich Sleshynsky. Sleshynsky is a Doctor of Mathematical Sciences, Professor of Novorossiysk University. After studying at the University for two years he was a Fellow at the Department of Mathematics of Novorossiysk University, defended his master’s thesis and was sent to a scientific internship in Berlin, where he listened to the lectures by K. Weierstrass, L. Kronecker, E. Kummer, G. Bruns. Under the direction of K. Weierstrass he prepared a doctoral dissertation for defense. He returned to his native university in 1882, and at the same time he was a teacher of mathematics in the seminary, Odesa high schools, and taught mathematics at the Odesa Higher Women’s Courses. Having considerable achievements in the field of mathematics, in particular, Pringsheim’s Theorem proved by Sleshinsky on the conditions of convergence of continuous fractions, I. Sleshynsky drew attention to a new direction of logical science. The most significant work for the development of national mathematical logic is the translation by I. Sleshynsky from the French language “Algebra of Logic” by L. Couturat. Among the most famous students of I. Sleshynsky, who studied and worked at Novorossiysk University and influenced the development of mathematical logic, one should mention E. Bunitsky and S. Shatunovsky. The second period of scientific work of I. Sleshynsky is connected with Poland. In 1911 he was invited to teach mathematical disciplines at Jagiellonian University and focused on mathematical logic. I. Sleshynsky’s report “On Traditional Logic”, delivered at the meeting of the Philosophical Society in Krakow. He developed the common belief among mathematicians that logic was not necessary for mathematics. His own experience of teaching one of the most difficult topics in higher mathematics – differential calculus, pushed him to explore logic, since the requirement of perfect mathematical proof required this. In one of his further works of this period, he noted the promising development of mathematical logic and its importance for mathematics. He claimed that for the mathematics of future he needed a new logic, which he saw in the “Principles of Mathematics” by A. Whitehead and B. Russell. Works on mathematical logic by I. Sleszynski prompted many of his students in Poland to undertake in-depth studies in this field, including T. Kotarbiński, S. Jaśkowski, V. Boreyko, and S. Zaremba. Thanks to S. Zaremba, I. Sleshynsky managed to complete the long-planned concept, a two-volume work “Theory of Proof”, the basis of which were lectures of Professor. The crisis period in mathematics of the early twentieth century, marked by the search for greater clarity in the very foundations of mathematical reasoning, led to the transition from the study of mathematical objects to the study of structures. The most successful means of doing this were proposed by mathematical logic. Thanks to Professor I. Sleshynsky, who succeeded in making Novorossiysk University a center of popularization of mathematical logic in the beginning of the twentieth century the ideas of mathematical logic in scientific environment became more popular. However, historical events prevented the ideas of mathematical logic in the domestic scientific space from the further development. (shrink)

The Monographs produced by the International Agency for Research on Cancer (IARC) apply rigorous procedures for the scientific review and evaluation of carcinogenic hazards by independent experts. The Preamble to the IARC Monographs, which outlines these procedures, was updated in 2019, following recommendations of a 2018 expert Advisory Group. This article presents the key features of the updated Preamble, a major milestone that will enable IARC to take advantage of recent scientific and procedural advances made during the 12 years since (...) the last Preamble amendments. The updated Preamble formalizes important developments already being pioneered in the Monographs Programme. These developments were taken forward in a clarified and strengthened process for identifying, reviewing, evaluating and integrating evidence to identify causes of human cancer. The advancements adopted include strengthening of systematic review methodologies; greater emphasis on mechanistic evidence, based on key characteristics of carcinogens; greater consideration of quality and informativeness in the critical evaluation of epidemiological studies, including their exposure assessment methods; improved harmonization of evaluation criteria for the different evidence streams; and a single-step process of integrating evidence on cancer in humans, cancer in experimental animals and mechanisms for reaching overall evaluations. In all, the updated Preamble underpins a stronger and more transparent method for the identification of carcinogenic hazards, the essential first step in cancer prevention. (shrink)

One main argument that has been offered in support of the Knowledge Account of Assertion is that it successfully makes sense of a variety of Moorean-paradoxical claims. David Sosa has objected to the Knowledge Account by arguing that it does not generalize satisfactorily to make sense of the oddity of iterated conjunctions of the form “p but I don’t know whether I know that p”. Recently, Martin Montminy has offered a defense of the Knowledge Account. In this paper, I show (...) that both Montminy’s and Sosa’s arguments fail. First, I argue that Montminy does not offer a good reply to Sosa; then I show that Sosa’s objection actually does not constitute a real threat to the Knowledge Account. (shrink)

Outdoor Education (OE) refers to organized experiential education that takes place in the outdoor, characterized by action-centered and thematic learning processes. Literature shows how OE may have beneficial effects on different areas of child development, including cognitive abilities, social skills and motor development. This relationship is not necessarily linear, but moderated by different variables. Until now, few studies have examined, using rigorous methods, the role of OE in children’s development and studies of preschool aged children remain lacking. The current study (...) aimed to explore teachers’ perceptions of children’s developmental trajectories over 2 school years, investigating whether teachers’ perceptions differed between two kindergartens, one characterized by a consolidated OE approach and the other one characterized by a more traditional method of education. The sample was composed of 20 teachers, evaluating 93 children aged 3-5 (M= 46.95 months, SD= 6.73; 42 males): 13 teachers were from a traditional kindergarten (Traditional Group- TG) and evaluated 52 children; 7 teachers were from an OE kindergarten (Outdoor Group – OE) and observed 41 children. All the teachers completed the Kuno Beller Developmental Tables (Beller, 1995), in order to describe specific child developmental areas in 4 consecutive moments during 2 school years (T1-T2: January-May 2014; T3-T4: October 2014-May 2015). The 20 teachers also completed the “Outdoor Activities/Trips Diary”, an instrument created for this study to collect qualitative data on the characteristics of outdoor activities. Results showed that, in all the developmental areas, OE teachers perceived higher scores over time were found for the Outdoor Group compared to the Traditional one. Specifically, GLM ANOVAs Repeated Measures revealed a significant interaction of the 2 variables Time and Groups (p<0.001): contrast analyses showed that OE children, compared to the TG children, were perceived by their teachers with higher levels in all developmental areas at T1 and T2, but not at T3 and T4. The findings suggest that the OE activites, compared to indoor ones and according to teachers' perceptions, offer greater opportunities to promote the child’s development at different levels. especially when children are younger. Future studies are recommended analyzing possible moderating variables and long term effects of OE. (shrink)

This text has already been published in Studies in Philosophy and Education, Feb. 2018, n° 37, p.103–107. As we all know it, writing and reading takes time. In the contemporary social and academic context, often shaped by a destabilizing sense of acceleration and urgency, protecting the moments required for such ‘time-consuming' activities is not something that can be taken for granted anymore. The way we commit to a specific task expresses as much about the meaning it may carry that what (...) we - Débats. (shrink)

This article presents an exploratory analysis of the metaphoric structure of five artistic paintings within “Think aloud” protocols, in which a group of 14 English speakers with a low self-rated level of expertise in art and history of art expertise were asked to verbalize all their thoughts, ideas and impressions of the artworks. The main findings of this study can be summarized as follows: (1) multiple interpretations for the same artwork are possible, (2) the interpretations of the metaphorical structures described (...) by the participants often diverge from those advanced by the researchers. These findings challenge the methods by which metaphor identification and analysis in pictorials is currently approached. As a matter of fact, most of the research in pictorial metaphors tends to reduce stimuli such as artistic paintings to unique metaphoric interpretations generally produced by a single researcher by means of introspection. By addressing this methodological problem in metaphor research, this article contributes to the development of a theoretical and operational participant-based framework that takes into account the role of metaphoric conceptualization within the domain of art and art cognition.

This is a well-behaved concept in Newtonian physics. But a center of gravity is not an atom or a subatomic particle or any other physical item in the world. It has no mass; it has no color; it has no physical properties at all, except for spatio-temporal location. It is a fine example of what Hans Reichenbach would call an abstractum. It is a purely abstract object. It is, if you like , a theorist's fiction. It is not one of (...) the real things in the universe in addition to the atoms. But it is a fiction that has nicely defined, well delineated and well behaved role within physics. (shrink)

Originally published 1968, the book examines the ways in which the definitions of education held by different groups with power have changed since 1800 and traces which social institutions exercised the preponderant influence on the growth of the English educational system during the seminal period in which the state system was founded and grew to its present position. Especial attention is given to the influence of the ideologies of the various social classes, to the growing demands of the economy on (...) the educational system and to changes in the structure of the family.

El propósito de este texto es ofrecer una visión general de la relación entre nación e historia en los debates que se generaron por parte de los historiadores y otros intelectuales de las ciencias sociales a finales del siglo XIX y durante gran parte del siglo XX. La reflexión central que se plantea consiste entonces en estudiar y mostrar cómo al mismo tiempo que las naciones modernas eran objeto de un proceso de redefinición política, en el escenario intelectual de las (...) ciencias sociales, y en particular de los historiadores, fueron apareciendo también un conjunto de debates y obras que intentaban problematizar y someter a consideración las relaciones que pretendían establecerse entre la nación y la historia como un elemento que las justificaba.

В работе рассматриваются некоторые актуальные аспекты творчества великих философов, писателей и поэтов - тех мыслителей, которые наиболее убедительно продемонстрировали генетическую связь философии и литературы.

Open peer commentary on the article “Perception-Action Mutuality Obviates Mental Construction” by Martin Flament Fultot, Lin Nie & Claudia Carello. Upshot: In my view, the clash between ecological psychology, enactivism, and constructivism in general has more to do with irreconcilable metaphysical and theoretical incommensurabilities than disagreements about specific mechanisms or processes of perception. Even with mutual enabling of action and perception, some internal process of self-modification is still needed if novel behavior is to be adequately explained.

The Nuremberg Trials of leading National Socialists established the principle that individuals may be legally punished, even by death, for obeying the laws of their country. Is there then a higher law by which enacted valid positive laws may be judged, so that persons subject to such laws would be duty-bound to defy them? In recent years the theory of natural law has been revived by a number of philosophers and jurists, who however often disagree sharply among themselves about the (...) proper methods for defining and deriving natural law. Howard Kainz surveys the history of natural law from its foreshadowing in ancient Greece down to the most recent controversies. Natural Law both introduces the subject to newcomers and sheds fresh light on such figures as Plato, Aristotle, Hume, Kant, Veatch, McInerny, Grisez, and Finnis. (shrink)

Frankish's argument for illusionism -- the view that there are no real instances of phenomenal consciousness -- depends on the claim that phenomenal consciousness is an 'anomalous phenomenon', at odds with our scientific picture of the world. I distinguish two senses in which a phenomenon might be 'anomalous': its reality is inconsistent with what science gives us reason to believe, its reality adds to what science gives us reason to believe. I then argue that phenomenal consciousness is not anomalous in (...) the first sense, and the fact that phenomenal consciousness is plausibly anomalous in the second sense is only problematic if it can be shown that our introspectively-based reasons for believing in consciousness are epistemically problematic. I finish by suggesting that Frankish might be motivated to adopt radical naturalism because he takes doing so to be the appropriate response to the incredible success of natural science. I outline a way of thinking about the history of science which undermines this motivation. (shrink)

Context: There is a movement to change education so that it is adequate to social expectations and uses the full potential of technology. However, there has been no significant breakthrough in this area and there is no clear evidence why. Problem: A potential issue explaining why education falls behind is the way educators focus on education. There is a possibility that a significant step in the learning process is routinely neglected. Method: Two different approaches to using IT in education are (...) tested in two different environments: a university level course based on constructionism and IBL projects for secondary school students. Results: It is possible to apply constructionism in education, but there are still problems. They are not related to how students construct knowledge, but how they deconstruct knowledge. Implications: The most significant problem of deconstruction is that it requires creative skills. This makes it very difficult to formalize it and to provide effective recommendations for its application. Constructivist Content: Deconstruction is a prerequisite of construction, thus deconstructionism deserves more attention and study. A proper application of deconstructionism will make it possible to reconstruct education in a way that is impossible with the current approaches. (shrink)

Purpose: At Silvio Ceccato’s suggestion, I invited Ernst von Glasersfeld to the “Séminaire Leibniz” which took place in Brussels, in February 1961. The paper he delivered then, Operational Semantics: Analysis of Meaning in Terms of Operations, was included in a Euratom internal report and is published here for the first time. Conclusion: These early works clearly show von Glasersfeld’s methodological and philosophical coherence as well as his faithfulness to Ceccato’s endeavour.
