The article provides a brief overview of the philosophical and methodological problems of modern collaborative research. Collaborations – distributed organizations with variable membership, consisting of a large number (sometimes several thousand) of participants – are common in experimental high-energy physics studying microcosm objects, elementary particles arising in collisions of beams of accelerated particles and nuclei at collider accelerators, as well as in biomedicine and climatology. The central issues are authorship, epistemic ownership and dependence in collaborations, the division of epistemic labor (...) in interdisciplinary research, as well as related issues of scientific organization – peer review and distribution of credit in a team. Formally, the author, conceived as a list of persons appearing as authors of a collaborative scientific work, seems to be defined by the specific participants of the collaboration core, i.e., is a construct. However, the question can also be understood as “What does it mean to be the author of a scientific work?”, and then the answer becomes much less certain. Authorship of thousand-people articles is justified psychologically as the desire for regular performance of a ritual, which allows demonstrating joint belonging to a certain tradition, such as a long experiment, affiliation with the “workshop” of scientists studying phenomena of the microworld, which allows scientists, despite of their daily preoccupation with technical routines, to distinguish themselves from non-epistemic communities (engineers, technicians). However, specific rules that determine exactly who and why are worthy of being included as co-authors have been undergoing changes in recent years. In addition to theoretical significance, many of the problems discussed are related to actual practical issues of scientometry and the organization of scientific research, and therefore approaches to their solution can be directly embodied in scientific policy.

In this article, the collective experimenter, arising in scientific projects from those modeled on the Alvarez group to megascience, is studied in the framework of the model of trading zones, as well as Actor-Network Theory. The collective experimenter is defined as a network of actors whose forms are trading zones, including the core – the empirical collective subject of cognition – and the peripheral part. The multitude of actors of the collective experimenter includes the core, as well as the community (...) of intentions and the external actors that are part of the periphery of the collective experimenter. Attention is focused on the differences between the author of epistemic claims, the subject of cognition and scientific collaboration. A classification of collective experimentalists is proposed that includes four types of ontologies. The classification is applied to JINR scientific projects, and within its framework projects of the Alvarez type, big science, proto-megascience and megascience are distinguished. Ways of developing projects to the megascience-level through the formation of cores-communicative communities in the structure of the collective experimenter are proposed. Premised on the results obtained, recommendations are formulated for the development of the JINR experiments program. (shrink)

Verification and validation of computer codes and models used in simulations are two aspects of the scientific practice of high importance that recently have been discussed widely by philosophers of science. While verification is predominantly associated with the correctness of the way a model is represented by a computer code or algorithm, validation more often refers to the model’s relation to the real world and its intended use. Because complex simulations are generally opaque to a practitioner, the Duhem problem can (...) arise with verification and validation due to their entanglement; such an entanglement makes it impossible to distinguish whether a coding error or the model’s general inadequacy to its target should be blamed in the case of a failure. I argue that a clear distinction between computer modeling and simulation has to be made to disentangle verification and validation. Drawing on that distinction, I suggest to associate modeling with verification and simulation, which shares common epistemic strategies with experimentation, with validation. To explain the reasons for their entanglement in practice, I propose a Weberian ideal–typical model of modeling and simulation as roles in practice. I examine an approach to mitigate the Duhem problem for verification and validation that is generally applicable in practice and is based on differences in epistemic strategies and scopes. Based on this analysis, I suggest two strategies to increase the reliability of simulation results, namely, avoiding alterations of verified models at the validation stage as well as performing simulations of the same target system using two or more different models. In response to Winsberg’s claim that verification and validation are entangled I argue that deploying the methodology proposed in this work it is possible to mitigate inseparability of V&V in many if not all domains where modeling and simulation are used.

Holding on to that distinction, I propose to relate verification to modeling and validation, which shares the common epistemology with experimentation, to simulation. To explain reasons of their intermittent entanglement I propose a weberian ideal-typical model of modeling and simulation as roles in practice. I suggest an approach to alleviate the Duhem problem for verification and validation generally applicable in practice and based on differences in epistemic strategies and scopes. (shrink)

In this paper, we addressed the problem of choosing a nuclear fuel cycle. Ethical problems related to the choice of a nuclear fuel cycle, such as the depletion of natural uranium reserves, the accumulation of nuclear waste, and the connection with the problems of nonidentity and distributive justice are considered. We examined cultural differences in attitudes toward nuclear safety and the associated ambiguities in the choice of a nuclear fuel cycle. We suggested that the reduction in consumption of natural uranium (...) does not seem to be a feasible way of reducing nuclear waste because of the nonidentity problem. (shrink)

This paper seeks to examine the roles and identities of engineers constituting one of the fundamental, but a completely indescribable community in modern big science with particle accelerators. Large communities of accelerator and detector specialists, which replaced experimenters and instrumentalists of the middle of the last century, themselves exhibit a complex structure and are divided. However, this division is in turn grounded on the division of those whose activities focus on the phenomena of nature considered independent of human beings and (...) those who design processes and phenomena of an artificial, technical nature. Nevertheless, in terms of their modus operandi and identity, the kinship between engineers and experimental scientists is considerable. I argue that such exclusion of the engineering community from epistemic practices can serve as an example of participatory injustice. As one of the ways to transcend participatory injustice, I suggest that the communities should be encouraged to work together in epistemically tantamount roles while structural hindrances to the mobility between communities need to be alleviated.

Simulation and Similarity is a novel and comprehensive account of, in first place, models and modeling. The author’s writing is exceptionally clear and intelligible. Simulation is referred to in the book only once, where it is defined as a kind of numerical analysis involving “computing the behavior of the model using a particular set of initial conditions” (82). Modeling, which is defined as “the indirect study of real-world systems via the construction and analysis of models” (4), appears to be the (...) primary focus of this book. This emphasis seems legitimate because the modeling practice precedes any simulation and is the key to its understanding as well.Chapter 2 “Three kinds of models” presents an account of the following kinds of models: concrete models (San Francisco Bay model being an example), mathematical models (Lottka–Volterra model of predation as an example), and computational models (illustrated by Schelling’s segregation model). First model example is a hydraulic one; the .. (shrink)

The paper focuses on the review of current literature on formal philosophy. Special attention is paid to the review of the book «Introduction to Formal Philosophy» [Hansson, Hendricks, 2018]. The book is a consistent introduction to the problems of formal philosophy, a research tradition that relies on the precise mathematical tools in order to study traditional philosophical problems. The methods of formal philosophy are successfully applied not only to the problems of ontology, epistemology and philosophy of language but also relevant (...) for the problems of ethics, axiology and social philosophy. The book demonstrates that it is not correct to identify formal philosophy with another area of study – philosophical logic, since formal philosophy uses not only logical methods of analysis, but also uses the tools of game theory, decision theory, probability theory, Bayesian statistics, and other theories. Although the book has a propaedeutic character, it also contains some open problems. These problems include the aggregation of the opinions of the group under the condition of a conflicting base of premises in the theory of public choice, there are still open problems in the interpretation of Arrow’s impossibility theorem and others. Certainly, formalization in itself is not a general solution to the particular philosophical problem, but only a tool that allows to formulate a problem in a more rigorous and precise way, which sometimes allows to reveal some unexpected consequences, some implicit contradictions and new solutions. Despite the importance of the concept of coherence in ethics, decision theory, philosophy of law, Bayesian epistemology, philosophy of science, the existing formalizations of the concept of coherence are highly specialized for epistemology, researchers recognize the lack of the relevant explanatory models. Overall, the book is an excellent introduction in to the field of formal philosophy, which provides a general overview of different aspects of formal philosophy and the opportunity to study particular research topics by means of an extensive bibliography accompanying each of the chapters.

This article explores contemporary approaches to the understanding and interpretation of the formation of inclusive society. The focus is on the investigation of the everyday experiences of individuals who face various limitations in their living conditions such as limited opportunities, special needs, and disabilities. The paper highlights the importance of considering the unique aspects of subjective time when systematically analyzing the functional characteristics and existential mechanisms of an inclusive society, which constitutes the living environment for people with disabilities. It points (...) out that the temporal intentionality of a mentally challenged individual manifests in a unique form of ordering, synchronization, and existence within various phenomena and events within the individual's mental imagery and inner experiences. The authors emphasize the necessity to differentiate two primary stages in an individual's perception and understanding of their actual existence—the evaluation stage and the stage of identifying prospects. The study shows how intentional temporality inherently transforms into individual time, revealing the peculiarities of internal experiences and the unique aspects of an individual's mental imagery. These are integral steps in the formation of a system of social events that are marked within the individual consciousness. The novelty of this study lies in the examination of intentionality within the framework of a disabled person's subjective time, a characteristic that is fundamentally individual yet resonates with the collective daily consciousness of disabled individuals within an inclusive micro-society.

The article shows that Borisov’s direct solution to the problem of skepticism about meaning using a special type of introspection is associated with the assumption of the agent’s direct access to their own consciousness. This assumption has two complicating consequences: the analogy with Moore’s paradox and the Platonic concept of meaning. It is also shown that direct access to meaning as a way of Borisov’s direct solution of the skeptical paradox significantly uses the performativity of the speech act, narrowing the (...) scope of analysis of the original problem. The little-studied problem of distinction in the analysis of the skeptical paradox of meaningful and formalized mathematics is noted. (shrink)

This book is about the relationship between necessary reasoning and visual experience in Charles S. Peirce’s mathematical philosophy. It presents mathematics as a science that presupposes a special imaginative connection between our responsiveness to reasons and our most fundamental perceptual intuitions about space and time. Central to this view on the nature of mathematics is Peirce’s idea of diagrammatic reasoning. In practicing this kind of reasoning, one treats diagrams not simply as external auxiliary tools, but rather as immediate visualizations of (...) the very process of the reasoning itself. Thus conceived, one's capacity to diagram their thought reveals a set of characteristics common to ordinary language, visual perception, and necessary mathematical reasoning. The book offers an original synthetic approach that allows tracing the roots of Peirce’s conception of a diagram in certain patterns of interrelation between his semiotics, his pragmaticist philosophy, his logical and mathematical ideas, bits and pieces of his biography, his personal intellectual predispositions, and his scientific practice as an applied mathematician.

The paper provides an analysis of Giuseppe Vitali’s contributions to differential geometry over the period 1923–1932. In particular, Vitali’s ambitious project of elaborating a generalized differential calculus regarded as an extension of Ricci-Curbastro tensor calculus is discussed in some detail. Special attention is paid to describing the origin of Vitali’s calculus within the context of Ernesto Pascal’s theory of forms and to providing an analysis of the process leading to a fully general notion of covariant derivative. Finally, the reception of (...) Vitali’s theory is discussed in light of Enea Bortolotti and Enrico Bompiani’s subsequent works. (shrink)

The paper deals with the Ukrainian translation of Immanuel Kant's Critique of Pure Reason (1781/87). We tried to answer the question of whether the Ukrainian reader who is willing to understand Kant's argument but does not understand the German original would be able to understand it by using only accessible now Ukrainian translation of this text. After checking the adequacy of terminological patterns applied in the translation and the correctness of the interpretation of overly complex syntax used by Kant, we (...) concluded that it is impossible to understand Kant's argument by reading only accessible now Ukrainian translation of this text. It is noted that an unavoidable condition for a professional translation's success is the professional community's agreement on how specific terms of a particular author should be translated so that there could not be any terminological confusion during discussions. It is unacceptable when different words in the original language denote the same term in the original. The translation is always an interpretation. Consequently, the reader has to interpret the interpretation, so the translator's maximum task is to preserve the original meaning's multidimensionality as much as possible. However, it is, of course, impossible to achieve the multidimensionality inherent in the original completely. We concluded that the translator of a classical philosophical text should be a researcher who has proven his or her understanding of both the text he or she translates and the tradition to which this text belongs. All these conditions were not adequately met in the case of the translation of Kant's Critique. Due to many inconsistencies in the available Ukrainian translation of the Critique of Pure Reason, errors in the interpretation of the Kant's syntax, and sometimes even Kant's vocabulary, the reader will not be able to understand the key Kant terms.

In The Sources of Normativity Korsgaard introduces her conception of practical identities understood as the source of moral obligations. This conception forms a point of transition from Korsgaard’s theory of action to her solution to the problem of the authority of moral norms. In order to describe how universal categorical reasoning is compatible with the moral content of particular practical decisions, Korsgaard needs to show how our contingent practical identities can be reconciled with what she defines as the universally shared (...) identity that expresses our humanity. To make this reconciliation work, she devises an argument for the public shareability of reasons amended by her reinterpretation of the Kantian as if principle. I suggest that, in doing so, Korsgaard steps too far away from Kant’s architectonic approach to the question of why moral norms bind us, and that, consequently, the Korsgaardian reconciliation between the two kinds of identities, as it stands, cannot be accomplished.

In spite of all the industrious efforts Peirce scholars have made so far, Peirce’s biography still retains a number of gaps, among which the problem of identity of Peirce’s second wife, Juliette Froissy, stands out most significantly. It is all the more important that, as some scholars suggest, the discovery of any reliable facts about Juliette could provide an explanation to some of the decisions Peirce had made, which irrevocably changed the course of his life, as well as his semiotic (...) theory. By courtesy of Professor Dr. Nathan Houser and the Peirce Edition Project, the writer of the present paper was granted access to the archive materials containing the Max H. Fisch — Maurice Auger correspondence and Victor Lenzen’s notes on Juliette. The paper aims at arranging the dispersed data obtained from these and other sources into a set of several distinct versions, which curiously refer to each other and collectively impose a certain order on some major abductions concerning Juliette’s identity.

The article presents an analysis of K.A. Rodin’s argument that after publishing of Peter Winch’s book “The Idea of Social Science” (1958) the discussions of rule-following problem concerning to social epistemology and the methodology of social studies have not had tangible results. It is shown by the example of modern legal studies that this conclusion is not valid. On the contrary, Wittgenstein’s problem of rule-following and the very idea of rule-shaped activity have proved to have a great importance for an (...) analytical legal philosophy and turned into an independent subject of study.

The Ecclesiastical History of Orderic Vitalis has been called `the greatest of all medieval chronicles'. Written in Normandy between 1114 and 1141, it is a detailed history of the Norman people and their conquests, full of vivid, often penetrating portraits of the lives and characters of kings and queens, lords and bishops, simple knights, and humble villagers. The chronicle gives a unique, authentic picture of feudal society during a period of rapid change in church and state which saw the emergence (...) of the Anglo-Norman realm, the spread of new forms of monasticism, and the launching of the Crusades.

InMind and World,John McDowell claims that we need to steer our way between bald naturalism and rampant platonism as two ways to explain our capacity to use concepts. Performing this task requires an explanation of how concepts can be both socially charged and, at the same time, genuinely involving the world as it really is. I suggest that McDowell’s explanation is insufficient and that Wilfrid Sellars’s idea of sense impressions might be used to clarify the relationship between social practices and (...) conceptual knowledge without incurring too much damage to the overall architectonics of McDowell’s theory.DansMind and World, John McDowell affirme que nous devons nous éloigner du naturalisme dépouillé et du platonisme exubérant comme étant deux manières d’expliquer notre capacité à utiliser des concepts.

The present paper is aimed at showing some correlations between Charles Peirce’s life, his intellectual habits as a logician and mathematician, his semiotic theory and his practice as a geodesist. For this purpose, it makes use of Peirce’s ideas about the nature of visual experience, some facts of his intellectual biography, and his definitions of sign and the term “virtual.” It appears that Peirce’s mature pragmatist and semiotic ideas find some support in his early practice as a scientist and a (...) mathematician, thus providing an interesting example of the intersection of scientific practice and philosophical speculation.

Continuing the investigations of X. Yu and others, we study the role of set existence axioms in classical Lebesgue measure theory. We show that pairwise disjoint countable additivity for open sets of reals is provable in RCA0. We show that several well-known measure-theoretic propositions including the Vitali Covering Theorem are equivalent to WWKL over RCA0.

The appearance in 1945 of the idea of the open texture of empirical concepts, which anticipated Friedrich Waismann’s thesis of a many-level-structure of language, led to a re-evaluation of “context”. It widens the sense of context that we are accustomed to mentioning as being Wittgenstein’s conception of meaning in his later philosophy. The new idea Waismann brought into the landscape is how to “clarify the context”, which is in a way a very non-Wittgensteinian question as well as an “explanation of (...) context”, where open texture plays a key role. But despite the amount of literature about open texture, this idea of Waismann is still not properly understood. Open texture must be situated as an obstacle to exhaustiveness of definition for internal reasons not only because of unforeseen conditions that could always arise in the future, but also by virtue of an a priori aspect of the texture of concepts. Thus, the main goal of this paper is to propose an interpretation of open texture as an immanent property of a concept, that is, as something that is underlying its nature. (shrink)

The article presents a careful analysis of the idea of the “open texture” of empirical concepts and the problems of verification in the way that they were formulated by Friedrich Waismann. The idea of the “open texture” means for Waismann a certain type of a linguistic indeterminacy or a sort of lack of definition, which must be distinguished from, and linked to, another types like vagueness or ambiguity. It is shown that empirical statements are not conclusively verifiable for two different (...) reasons: the incompleteness of description of the material object and the open texture of the terms involved. We cannot conclusively verify statements in which the empirical concepts are used, because we cannot define these concepts in an exhaustive way because of their open texture. Thus, the definition of the concept will be incomplete. Waismann’s approach to definition plays here a key role, and it is directly related to the open texture of concepts. The author proposes interpreting the open texture as an immanent property of the concept, as something that is embedded in it a priori, and which can cause a vagueness. Nevertheless, an open texture must be distinguished form a vagueness. This leads to the conclusion that an open texture is a possibility of vagueness; vagueness can be remedied by giving more accurate rules, open texture cannot. In this sense, the “open texture” of a language allows for a more precise definition of concepts (by adjusting the definition) if appropriate circumstances arise. This justifies the thesis that the argument of the open texture is the ontological basis of the linguistic anti-reductionism of Friedrich Waismann. (shrink)

This paper compares Charles Peirce’s and Robert Brandom’s conceptions of normative objectivity. According to Brandom, discursive norms are instituted by practical attitudes of the members of a community, and yet the objectivity of these norms is not reducible to social consensus. Peirce’s conception of normative objectivity, on the contrary, is rooted in his idea of a community of inquiry, which presupposes a consensus achievable in the long run. The central challenge in both cases is to explain how the norms that (...) all members of a community take to be correct differ from those that are correct objectively. I argue that, in meeting the challenge of reconciling the social character of knowledge and the objectivity of norms shared by a community of knowers, Brandom’s approach might benefit from the Peircean idea of the ultimate agreement.

The article presents a detailed consideration of the arguments from the symposium “Verifiability”, which was held on July 14, 1945 in London, proposed by Scottish philosopher and theologian Donald MacKinnon, Austrian logician and mathematician Friedrich Waismann and English logician and philosopher of science William Kneale. MacKinnon’s approach to verifiability was based on the metaphysics of fact, while Waismann and Kneale’s approach was based on the semantic specificity of empirical concepts (“open texture” and context of use) and on the truth-values of (...) empirical propositions. The symposium in question is interesting primarily because it is the last meaningful discussion on the concept of verifiability in the form in which it was understood by the Vienna Circle. Despite the fact that, in the coming years, this concept received a completely different interpretation, which stands away from the original source, the 1945 symposium could be rightfully treated as a canonical discussion on verifiability in the sense that nothing like this has ever happened in the philosophy after.

This paper deals with the so-called “external history” of the origin of Critique of the power of judgment that is based primarily on the philosopher’s correspondence in the period between May 1787 and October 1789. Two letters from Kant to Reinhold (28.12.1787 and 12.05.1789) as well as modifications in the interpretation of the term “aesthetics” in the first Critique (KrVA 22, B 35-36) are crucial for the evolution of the project Critique of Taste in the book Critique of the Power (...) of Judgment. Special attention was paid to the debate between some modern scholars and editors about the importance of the reports on ‘Grundlegung’ / ‘Grundlage’ of Critique of Taste in the initial phase of work on the text. However, the available evidence does not allow us to reconstruct the “internal history” of the development of Kant’s thought during the period of writing the third Critique. Some modern scholars try to establish other objective criteria for this kind of reconstruction by identification in the text of Critique direct or hidden hints or citations to the literature of the 18th century. The author considers that the use of so-called “reflections” from the philosopher’s manuscript heritage, which can be seen as the formation and development of certain concepts of Kant’s theory, can be fruitful. The well-known problem of dating the reflections can be partially solved if terminus a quo will be not the published works, but Kant’s lectures on anthropology and logic taught at that time.

The article examines K.A. Rodin’s thesis on the possibility of including Wittgenstein’s remarks on intention and action in the context of legal philosophy research. It is shown that although the concepts of intention and intentional action are relevant to the philosophy of law, Wittgenstein’s own ideas did not have a significant impact on their relevance (and some of them did not have it at all). This influence is confined to the fact that, like Wittgenstein, many jurists and legal theorists, mainly (...) those who were influenced by the ideas of H.L.A. Hart, also objected to the causal theory of action. However, the influence is limited to this approach. (shrink)

The paper investigates the way in which criminal law of most countries allocates to the idea of intention, as one of the principal determinants of liability to punishment. All civilized penal systems make liability to punishment for at any rate serious crime dependent not merely on the fact that the person to be punished has done the outward act of a crime, but on his having done it in a certain state of frame of mind. These mental or intellectual elements (...) are many and various andare collected together in the legal terminology under the description of a guilty mind. But the most prominent, of these mental elements, and in many ways the most important, is a man's intention. The law's concern with intention generates a number of problems, some of which are discussed in this paper. It is argued that even before one reaches these problems there is a more fundamental question to be addressed: what is a man's intention? This is a question which, quite apart from the law, philosophers have found both intriguing and difficult to answer. The author discusses howit can add complexity to what is considered intentional in criminal law. (shrink)

During its hundred-year history, Ludwig Wittgenstein’s Tractatus Logico-Philosophicus has undergone a variety of interpretations and explanations. But the significance of this work cannot be limited to an assessment of whether it had an impact on the development of logical positivism or not. Similarly, the reading of Tractatus cannot be reduced to just an ethical or some other readings. This article proposes to study a possible reading of “Tractatus” in terms of legal philosophy, which is based on the relation between facts, (...) values and norms, as well as on how interesting it could be (or would be) for legal philosophy.
