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)

The successful early acquisition of reading literacy represents a crucial learning process determining the further course of academic development (Stanovich, 2009). During this process, interactions between children and their proximal social environment are of utmost importance. Therefore, we introduce a systemic framework for the development of learning potential (e.g., Mudrak et al., 2015, 2019, 2019b; Ziegler & Stoeger, 2017) and explore the interactions between the social and motivational processes associated with reading literacy development in school-age children. We base our analysis (...) on a representative Czech sample of fourth-grade pupils involved in the Progress in International Reading Literacy study (PIRLS, Martin et al., 2016). On the basis of the systemic framework, we hypothesized hierarchical relationships among family socioeconomic status, related developmental resources (including parental support, expectations, and reading resources), children’s reading motivation (including reading engagement and reading confidence), and manifested learning outcomes (including school grades and reading competence). We implemented three structural equation models to test the hypothesized relationships. The first model tested the direct effect of developmental resources on reading competence. The second model included the motivational variables as mediators between resources and competence. The third model included school grades as mediators between resources and motivational variables. Our analyses indicated the good fit of the proposed models. The final model explained 37.8 % of the variance in children’s school grades and 46.5 % of the variance in reading literacy test scores (compared to 34.8 % in the first model). Moreover, parental socioeconomic status was strongly associated with parental expectations, which were associated with reading confidence, partially through the effect of parental expectations on children’s school grades. Reading confidence was the main predictor of reading literacy within the model, followed by the direct effects of parental resources. The results illustrate complex processes through which the family environment affects the development of learning competencies such as reading literacy by providing children with the relevant social and material resources associated with their motivation and school outcomes. We discuss some of the reasons that these relationships may take place and consider their implications for educational practice. (shrink)

Many experimental found footage films base their meanings and effects on an interaction between the figurative content of the image and its material-technological underpinnings. Can this interaction arise accidentally without artistic appropriation? A recently digitised film by the Czech cinema pioneer Jan Kříženecký, Opening Ceremony of the Čech Bridge (1908), presents such an exercise in accidental aesthetics. At one point, the horizontal and vertical trembling of the cinematograph – obtained from the Lumière brothers – translates into a trembling of the (...) figures on the bridge so precisely that the figurative and material spheres appear to cooperate towards a common aesthetic goal. To account for such phenomena, film theory, found footage filmmaking, and archival practice need to join forces with philosophy. More specifically, Gilbert Simondon's notion of transduction, a process based on the intersection of diverse realities within a domain, allows us to conceptualise the paradoxical interaction between the figurative and material dimensions and the unintentional meanings that arise out of it. Transduction enables the distribution of elements between these heterogeneous spheres while maintaining a certain stability within a system. In the case of archival films in which transduction occurs without prior intention or expectation, transduction can be foregrounded and prolonged. The connection between transduction and the “trembling meaning” of Opening Ceremony, understood within the wider context of camera instability in experimental found footage, will uncover the aesthetic potentialities held by the autonomous creativity of film matter and its interferences with the figurative content.

Zjawisko ludobójstwa zostało zdefiniowane, opisane i skodyfikowane dopiero w kontekście II wojny światowej i po jej zakończeniu (Rafał Lemkin, Konwencja ONZ z 1948 r.). Jednak masowa przemoc spełniająca kryteria ludobójstwa sięga głęboko w czasy przednowoczesne. Podobnie współczesne ludobójstwa, w tym Holokaust, zawierają motywy związane ze światem średniowiecznym (i wczesnonowożytnym). Należą do nich m.in. _a priori _ostracyzacja ofiar oparta na celowym (ahistorycznym) aktualizowaniu realiów średniowiecznych, wykorzystywanie i nadużywanie argumentów religijnych oraz kościelnych itp. Rozdział dotyczy tłumaczenia tych symboli w kontekście wybranych, znaczących (...) ludobójstw XX w. (shrink)

This article will introduce Isaac Newton’s fundamental methodological concepts applied for a solution concerning a question of gravity in his Principia Mathematica. The method of deduction of propositions from phenomena can be described as demonstrative induction. The main aim is to show that this method proposed by Newton explicitly contains a criticism of hypothetico-deductive methodology as an inadequate approach to the study of nature. As opposed to hypothetico-deductive method, demonstrative induction is capable of producing theories with much richer empirical and (...) epistemological value. Delimitation against hypothetically deduced theories is closely connected with criticism of mechanical materialism, most notably in a form proposed by René Descartes. Consequently, it has led Newton to not only reject the universality of mechanical premise but also to certain level of immunization against all competitive hypothetically based theories. (shrink)

The claim that having aesthetic properties supervenes on having non-aesthetic properties has been widely discussed and, in various ways, defended. In this article, I aim to demonstrate that even if it is sometimes true that a supervenience relation holds between aesthetic properties and ‘subvenient’ non-aesthetic ones, it is not the interesting relation in the neighbourhood. As we shall see, a richer, asymmetric, and irreflexive relation is required, and I shall defend the claim that the increasingly popular relation of grounding does (...) amuch better job than supervenience.

We study search problems and reducibilities between them with known or potential relevance to bounded arithmetic theories. Our primary objective is to understand the sets of low complexity consequences of theories Si2 and Ti2 for a small i, ideally in a rather strong sense of characterization; or, at least, in the standard sense of axiomatization. We also strive for maximum combinatorial simplicity of the characterizations and axiomatizations, eventually sufficient to prove conjectured separation results. To this end two techniques based on (...) the Herbrand's theorem are developed. They characterize/axiomatize Σb1-consequences of Σb2-definable search problems, while the method based on the more involved concept of characterization is easier and gives more transparent results. This method yields new proofs of Buss' witnessing theorem and of the relation between PLS and Σb1, and also an axiomatization of Σb1. (shrink)

Metaphysical theories are beautiful. At the end of this book, Jiri Benovsky defends the view that metaphysical theories possess aesthetic properties and that these play a crucial role when it comes to theory evaluation and theory choice.Before we get there, the philosophical path the author proposes to follow starts with three discussions of metaphysical equivalence. Benovsky argues that there are cases of metaphysical equivalence, cases of partial metaphysical equivalence, as well as interesting cases of theories that are not equivalent. (...) Thus, claims of metaphysical equivalence can only be raised locally. The slogan is: the best way to do meta-metaphysics is to do first-level metaphysics.To do this work, Benovsky focuses on the nature of primitives and on the role they play in each of the theories involved. He emphasizes the utmost importance of primitives in the construction of metaphysical theories and in the subsequent evaluation of them.He then raises the simple but complicated question: how to make a choice between competing metaphysical theories? If two theories are equivalent, then perhaps we do not need to make a choice. But what about all the other cases of non-equivalent "equally good" theories? Benovsky uses some of the theories discussed in the first part of the book as examples and examines some traditional meta-theoretical criteria for theory choice (various kinds of simplicity, compatibility with physics, compatibility with intuitions, explanatory power, internal consistency,...) only to show that they do not allow us to make a choice.But if the standard meta-theoretical criteria cannot help us in deciding between competing non-equivalent metaphysical theories, how then shall we make that choice? This is where Benovsky argues that metaphysical theories possess aesthetic properties – grounded in non-aesthetic properties – and that these play a crucial role in theory choice and evaluation. This view, as well as all the meta-metaphysical considerations discussed throughout the book, then naturally lead the author to a form of anti-realism, and at the end of the journey he offers reasons to think better of the kind of anti-realist view he proposes to embrace. www.jiribenovsky.org.

The main aim of this study is to explain passage 35b4-37a2 of Plato’s Timaeus which deals with three main topics: the mathematization of the world’s soul, its movement, and its binding to the world’s body. First, it is argued that the mathematical structure of the world-soul allows it to participate in and be sensitive to harmony, which is essential for the correct workings of its cognitive capacities. Second, the division of the world-soul to the circle of the same and the (...) circles of the different and its self-motion comes in. This allows it to ‘touch’ and cognize the forms and the material things, as well as rule the movement of the corporeal world and care for it. In this aspect, the world-soul continues the process that started with the original creative act of the demiurge. Third, it is argued that the description of the world-soul’s binding to the world-body entails its conception as a spatially extended entity, which, in turn, explains of the possibility of an interaction between the corporeal world and its soul.

In this book, Jiri Benovsky takes a stand for a variant of panpsychism as being the best solution available to the mind-body problem. More exactly, he defends a view that can be labelled 'dual-aspect-pan-proto-psychism'. Panpsychism claims that mentality is ubiquitous to reality, and in combination with dual-aspect monism it claims that anything, from fundamental particles to rocks, trees, and human animals, has two aspects: a physical aspect and a mental aspect. In short, the view is that the nature of (...) reality is 'phental' (physical-mental). But this does not mean, according to the author, that rocks and photons think or have conscious experiences, in the sense in which human animals have experiences. This is where pan-proto-psychism enters the picture as being a better theoretical option, where the mental aspects of fundamental particles, rocks, and trees are not experiential. Many hard questions arise here. In this book, Benovsky focuses on the combination problem: in short, how do tiny mental aspects of fundamental particles combine to yield macro-phenomenal conscious experiences, such as your complex experience when you enjoy a great gastronomic meal? What makes the question even harder is that the combination problem is not just one problem, but rather a family of various combination issues and worries. Benovsky offers a general strategy to deal with these combination problems and focuses on one in particular – namely, the worry concerning the existence of subjects of experience. Indeed, if standard panpsychism were true, we would need an explanation of how tiny micro-subjects combine into a macro-subject like a human person. And if panprotopsychism is true, it has to explain how a subject of experience can arise from proto-micro-mental aspects of reality. Benovsky shows that understanding the nature of subjectivity in terms of the growingly familiar notion of mineness in combination with a reductionist/eliminativist view of the self, allows us to have a coherent picture, where this type of combination problem is avoided, without throwing the baby out with the bathwater.

David Lewis’ modal counterpart theory falls prey to the famous Saul Kripke’s objection, and this is mostly due to his ‘static’ ontology of possible worlds. This paper examines a genuinely realist but different, branching ontology of possible worlds and a new definition of the counterpart relation, which attempts to provide us with a better account of de remodality, and to meet satisfactorily Kripke’s claim, while being also ontologically more ‘parsimonious’.

History and the philosophy of science have played a very important role in dialectical materialism; their results have been destined to support the correctness of the ideas of Marxist philosophers, especially in their application in historical materialism.From this point of view, the circumstances of the origin of the works of the Marxist classics cannot be neglected: Engels wrote hisDialectics in Nature in the period of classical physics, and Lenin published hisMaterialism and Empirio-Criticism at the beginning of the 20th century when (...) our modern physics first began: shortly before the publication of Lenin's book, Röntgen and Becquerel discovered new kinds of radiation, Balmer published his ideas concerning the regularity of the hydrogen spectrum, Plank wrote his first articles about the elementary quantum and Einstein published his three famous articles (1905).

In this paper, I explore several versions of the bundle theory and the substratum theory and compare them, with the surprising result that it seems to be true that they are equivalent (in a sense of 'equivalent' to be specified). In order to see whether this is correct or not, I go through several steps : first, I examine different versions of the bundle theory with tropes and compare them to the substratum theory with tropes by going through various standard (...) objections and arguing for a tu quoque in all cases. Emphasizing the theoretical role of the substratum and of the relation of compresence, I defend the claim that these views are equivalent for all theoretical purposes. I then examine two different versions of the bundle theory with universals, and show that one of them is, here again, equivalent to the substratum theory with universals, by examining how both views face the famous objection from Identity of Indiscernibles in a completely parallel way. It is only the second, quite extreme and puzzling, version of the bundle theory with universals that is not be equivalent to any other view; and the diagnosis of why this is so will show just how unpalatable the view is. Similarly, only a not-so-palatable version of the substratum theory is genuinely different from the other views; and here again it's precisely what makes it different that makes it less appealing.

In this book, Jiri Benovsky defends the view that he doesn't exist. In this book, he also defends the view that this book itself doesn't exist. But this did not prevent him to write the book, and although in Benovsky's view you don't exist either, this does not prevent you to read it. Benovsky defends a brand of non-exceptionalist eliminativism. Some eliminativists, typically focusing on ordinary material objects such as chairs and hammers, make exceptions, for instance for blue whales (...) (that is, living beings) or for persons (that is, conscious organisms). Benovsky takes one by one all types of allegedly existing objects like chairs, whales, and persons and shows that from the metaphysical point of view they are more trouble than they are worth – we are much better off without them. He thus defends an eliminativist view about ordinary objects as well as the 'no-Self' view, where he explores connections between metaphysics, phenomenology, and Buddhist thought. He then also considers the case of aesthetic objects, focusing on musical works and photographs, and shows that the claim of their non-existence solves the many problems that arise when one tries to find an appropriate ontological category for them, and that such an eliminativist view is more natural than what we might have thought. The arguments provided here are always topic-specific: each type of entity is given its own type of treatment, thus proving a varied and solid foundation for a generalized, non-exceptionalist, full-blown eliminativist worldview.

Abstract: There are two traditionally rival views about the nature of time: substantivalism that takes time to be a substance that exists independently of events located in it, and relationism that takes time to be constructed out of events. In this paper, first, I want to make some progress with respect to the debate between these two views, and I do this mainly by examining the strategies they use to face the possibilities of ‘empty time’ and ‘time without change’. As (...) we shall see, the two allegedly very different rival views are much less different than has been thought: their structure is extremely similar, their strategies are extremely similar, and they can both face the possibilities of ‘empty time’ and ‘time without change’ in the same way. Thus, I argue in favour of a certain kind of equivalence between the two views; I discuss a Strong and a Weak version of this claim; and I provide reasons for endorsing the former. I also discuss the parallel between this pair of views about the nature of time and another analogous pair of views: the bundle theory and the substratum theory about the nature of material objects, with respect to the problem with Identity of Indiscernibles.

Model-theoretic concepts of saturation and categoricity are studied in the context of accessible categories. Accessible categories which are categorical in a strong sense are related to categories of $M$-sets ($M$ is a monoid). Typical examples of such categories are categories of $\lambda$-saturated objects.

We investigate the interactions of formula complexity in weak set theories with the axioms available there. In particular, we show that swapping bounded and unbounded quantification preserves formula complexity in presence of the axiom of foundation weakened to an arbitrary set base, while it does not if the axiom of foundation is further weakened to a proper class base. More attention is being paid to the necessary axioms employed in the positive results, than to the combinatorial strength of the positive (...) results themselves. (shrink)

In its jurisprudence relating to Article 267 TFEU, the Court of Justice of the European Union seems to oscillate between two different approaches. According to the jurisprudential mainstream, the preliminary ruling is an instrument of dialogue between national courts and the Court of Justice. This constant dialogue can fulfill the role assigned to the Court to ensure consistency of interpretation and application of Union law. Another line of cases, however, seems to make preliminary rulings means for individuals to ensure their (...) rights which derive from EU law. These two visions of the preliminary references recently have been opposed in discussions about a particular aspect of the preliminary procedure, which is the late withdrawal of the question referred by the national court. In fact, when the national court considered that the response of the Court of Justice was not “necessary to render judgment,” it could, at any time, including both before and after the deliberate publication, date the judgment to the parties and remove this issue. Therefore, the jurisdiction of the Court of Justice became dependent on matters of procedure (dealings between the parties, amicable agreements, etc.) that occurred in extremis before the national court, which sometimes cast doubt on a possible manipulation of the Court by the parties to the main proceedings. It became necessary to find a solution to solve this problem. The two different visions were then compared. If the preliminary ruling is conceived as an additional instrument for the rights that individuals derive from EU law, there is no need for the Court of Justice of the European Union to make a decision when the dispute is resolved before the national court and the defendant has obtained satisfaction. Conversely, if the preliminary ruling is conceived as an instrument to ensure the uniform application and interpretation of EU law, this judgment may be necessary. In fact, without deciding in abstracto, the Court in its judgement will anchor an interpretation that should be applied in all similar cases in the courts of the 27 Member States. In this case, a judgment may still be necessary, even if the dispute before the national court ended off. In order to preserve this approach, the new Rules of Procedure now contain a provision in Article 100 (1) which reads as follows: “The Court shall remain seised of a request for a preliminary ruling for as long as it is not withdrawn by the court or tribunal which made that request to the Court. The withdrawal of a request may be taken into account until notice of the date of delivery of the judgment has been served on the interest persons referred to in Article 23 of the Statute”. Thus, the late withdrawal of a request for a preliminary ruling is clearly limited in time and, even if such removal would occur in extremis, the judgment of the Court will be delivered in the interest of interpretation and uniform application of Union law.

Consistent application of dialectical materialism leads Marxism-Leninism to the assertion that matter is infinite in its properties. However, the history of physics shows that the various levels of matter possess geometric dimensions that originate at the lowest level and continue through the others. The search for absolute natural constants — which Planck called the most pleasant task of physics — shows the conviction of the physicists that there is a limit to the parameters, a limit beyond which matter is no (...) longer divisible.

Na úvod připomínám medailon Josefa Zumra k Lubošovým šedesátinám ve Filosofickém časopisu 1995, jako doklad, že našeho tehdejšího vedoucího katedry si vážili nejen filosofové z Brna. Luboš se narodil ve stejném roce jako já, ale středoškolská studia stihl dokončit o rok dříve. Tak se stalo, že jsem se s ním v roce 1950 na Filosofické fakultě setkal jako s učitelem- -asistentem (na jeho přednášce z etiky) a on se mnou jako s jedním ze svých prvních univerzitních posluchačů filosofie. Když jsem (...) s ním od roku 1954 působil na jedné katedře, setkávali jsme se nejen „služebně”, ale i jako kamarádi mimo školu; nezapomenutelné mi zůstávají např. naše zájezdy na slovenskou chalupu k Pavlu Páclovi, kde jsem se utvrzoval v poznání, jak přirozeně Luboš umí být výborným společníkem i v takovém prostředí (nejen při karetních hrách, ale i když jsme se snažili přispět k údržbě Pavlovy chalupy a k její přípravě na zimní období). Pokusil jsem se povědět pár slov o Lubošově vztahu k rodině, v níž se narodil, k jeho vlastní rodině, k rodnému kraji, a ovšem i Lubošovi učiteli, všemi studenty oblíbeném a váženém. Muselo - bohužel - nakonec dojít i na slova obdivu k jeho statečnému zápasu s nemocí, které posléze podlehl. (shrink)

This article addresses several aspects of interaction between procedural and conflict rule regulation in private international law both of which are subject to unification process under the European Community law. They are interdependent of each other, and use the same or similar terms on many occasions. Problems with interpretation arise in application of these legal regulations. The European Court of Justice addresses them more or less successfully. As demonstrated in this article, the interpretation of procedural rules of regulation may contribute (...) to the clarification of the conflict rules and vice versa. It can be even said that the mutual interaction of conflict rules and procedural rules through interpretation is both unavoidable and desirable. (shrink)

In this paper, I examine various theories of persistence through time under presentism. In Part I, I argue that both perdurantist views (namely, the worm view and the stage view) suffer, in combination with presentism, from serious difficulties and should be rejected. In Part II, I discuss the presentist endurantist view, to see that it does avoid the difficulties of the perdurantist views, and consequently that it does work, but at a price that some may consider as being very high: (...) its ontological commitments to platonic universals and to the substratum theory, that as we shall see follow from the combination of endurantism with presentism, will perhaps not be to everyone's taste.

The eternalist endurantist and perdurantist theories of persistence through time come in various versions, namely the two versions of perdurantism: the worm view and the stage view , and the two versions of endurantism: indexicalism and adverbialism . Using as a starting point the instructive case of what is depicted by photographs, I will examine these four views, and compare them, with some interesting results. Notably, we will see that two traditional enemies—the perdurantist worm view and the endurantist theories—are more (...) like allies : they are much less different than what is usually thought, and some alleged points of central disagreement fall prey to closer scrutiny. The aim of this paper is to examine carefully all those points, and to call attention to the places where the real differences between these views lie. I will then turn to the perdurantist stage view, and claim that with respect to some central issues it is the view that is the most different from the other three, but that in some places the reason why it different is also the reason why it is less satisfactory.

Sometimes, I like to write 'philosophical stories' that explain a philosophical problem, and this book is a compilation of five such stories. So this is a book for non-philosophers or for beginners in philosophy. There is a story of a bald punk that allows me to explain theories of vagueness, a story about brains in vats that gives rise to a discussion of scepticism about the external world, a story about a theft in a museum where the thief is condemned (...) twice (once for stealing a statue, and once for stealing a piece of bronze of which the statue was made), a time travel story, and a ship od Theseus revisited story. I hope to have achieved something that is both fun and serious and that will give a good picture of what philosophy is to the general public. The book is also intented for first or second year philosophy students, who can find there a starting point for understanding some debates. (shrink)

Dans ce livre sur les photographies, l'auteur defend l'idee que les photographies n'existent pas. En effet, pour le philosophe, la nature des photographies est assez evasive. Quel type d'entites sont-elles? Des objets materiels concrets comme des tirages papier? Des types abstraits qui peuvent etre instanties dans de nombreuses formes tres diverses (tirages, fichiers, images a l'ecran,...)? Nous allons voir qu'aucune categorie metaphysique traditionnelle ne parvient a rendre compte de la nature des photographies, et je soutiendrai alors la these que les (...) photographies n'existent pas. Mais qu'elles existent ou pas, les photographies soulevent un certain nombre de questions philosophiques importantes.

Nous allons egalement aborder le cas particulier de representation de la duree temporelle: une image statique, telle qu'une photographie, comment peut-elle representer un intervalle temporel non-instantane.

The paper deals with the problematic of concept and image as independent forms of mediating the thought. A specific role in incorporating the media of concept and image into the system of thought is played by the mediality itself, which operates as an entity mediating between heterogeneous worlds. The symbolized messages of the concept and image thus represent using the dispositive of representation between the visual and intellectual worlds. The author takes the concept as the initial form of thought, which (...) describes the object from the perspective of its being without making any propositions about it; the image, on the other hand, is taken as a sensory representation of the object. However, each of them is only a particular form of mediation. Representing a concept thus means taking the thought as a conceptual representation. (shrink)

The subject takes part in and constructs what it perceives, shifting, thus, the presuppositions, that is, the ‚pre-formats‘ of this construction into the background, out of reach of that which is manifesting itself. In fact, within the framework of its own construction, the subject does not dispose of any possibilities of transferring other heterogeneous settings into a unique target format upon which the world of objects is constructed. In order to achieve this the subject needs a determinate interactive interface, i. (...) e., mediation. Access to mediation, that is, to the interfaces combining the different settings, to complexity and to the real, helps us to understand the differences that become accessible to us. Furthermore, access helps us to reach an adequate understanding of the role of the subject in the world, a world in which the subject is not only mechanically constructed but, above all, mediated accordingly.
