In lieu of an abstract, here is a brief excerpt of the content:Preface: Virtual Entities in ScienceRobert Harlander, Jean-Philippe Martinez, Friedrich Steinle, and Adrian WüthrichIt is not only since the sudden increase of online communication due to the COVID-19 situation that the concept of the “virtual” has made its way into everyday language. In this context, it mostly denotes a digital substitute for a real object or process. Virtual reality is perhaps the best-known term in this respect. With these digital (...) connotations, “virtuality” has also been used in science and research: Chemists use virtual laboratories, biologists do virtual scanning of molecular structures, and geologists engage in virtual field trips. But the concept of the virtual has a much longer tradition, dating back to long before the dawn of the digital age. Virtual images and virtual displacements were introduced in classical physics already in the late seventeenth and eighteenth centuries, respectively. They represent auxiliary objects or processes without instantiation, with the purpose of efficiently describing specific physical systems. In today’s physics, the term “virtual” is mostly associated with the quantum world, first and foremost with the “virtual particle” of quantum field theory. It has become such an integral part of modern high energy physics that its ontological character may be considered to go beyond the purely auxiliary, which is typically associated with the virtual. [End Page 263]In other disciplines, however, use of the term virtual without a digital connotation is much rarer. While concepts like “virtual adrenaline” show up in physiological research around 1940s, and Charles Darwin, in a private note in January 1840,1 spoke of “virtual change” in the context of embryology, these examples seem to be singular occurrences of entities that were explicitly called “virtual.” The basic idea behind the terminology of the virtual, however, might be much more common, even outside of physics. The “invisible hand” in economics, or the “vital force” in biology, for instance, may carry aspects of a virtual entity, even if they have not been referred to that way.These different observations raise several questions about the status of virtual entities in science. What has led scientists to call one entity “virtual” and not another? Do all virtual entities in science have the same roots and meet the same characteristics? Are they more than auxiliary objects or processes? Why does physics seem to occupy a specific position with respect to the use of the notion of virtuality? These are some points that led us to discuss virtual entities in science during a workshop, out of which grew the present collection. We invited contributions that addressed the historical formation and philosophical interpretation of concepts of virtual entities in physics and other disciplines—in whatever terms they may come. The main goal of the workshop was to bring to the fore similarities and differences in the meanings and functions of these concepts, so as to be able to precisely characterize why certain entities are considered virtual in specific contexts, why a different terminology was often used in each individual case, and in what sense the virtual entities relate to the real world.The organization of the workshop was part of our project “The formation and development of the concept of virtual particles,” a subproject of the Research Unit “The Epistemology of the Large Hadron Collider,” funded by the Deutsche Forschungsgemeinschaft (DFG) and Der Wissenschaftsfonds (FWF). The workshop took place online on four consecutive Fridays in March 2021. It brought together contributors who discussed the role of the concept of the virtual in theoretical as well as experimental activities, and investigated into the origins of the terminology of the virtual as it was applied to the various disciplines of natural science. Dealing with historical, philosophical, but also methodological questions, the presentations covered a wide time range, from the Middle Ages to the present day. While physics naturally emerged as the dominant field, natural philosophy, computer science and biology were also addressed. The papers in this volume were contributed by participants in this workshop and approach the subject from different angles. [End Page 264]First, Friedrich Steinle provides us with an introductory piece that reflects on the specific meaning of the use of the term ‘virtual’ in science. He highlights and... (shrink)

The famous theory of undecidable sentences created by Kurt Godel in 1931 is presented as clearly and as rigorously as possible. Introductory explanations beginning with the necessary facts of arithmetic of integers and progressing to the theory of representability of arithmetical functions and relations in the system (S) prepare the reader for the systematic exposition of the theory of Godel which is taken up in the final chapter and the appendix.

In lieu of an abstract, here is a brief excerpt of the content:Why the Phenomenology Remains FoundationalRobert Harland (bio)Keywordspsychology, cognitive-behavioral therapy (CBT), phenomenology, psychiatry, depressionDemian Whiting in his paper criticizes an exclusively cognitive approach to the treatment of emotional problems. There is no doubt that the cognitive model of the mind has been recently in the ascendancy and therapies based on it are to be found in almost every subspecialty of psychiatry. Cognitive-behavioral therapy (CBT) in particular is "discovered" as (...) being effective in everything from posttraumatic stress disorder to psychosis. The heartland of the approach is and remains anxiety and depression, the two most common emotional states that psychiatrists and psychologists are asked to deal with. As Dr. Whiting describes, leaving aside the behavioral aspects, the basic principle is about eliciting and challenging distorted cognitions. Cognitive theory suggests that distorted cognitions are the cause of, the substance of, and the maintaining factors in most if not all depression and anxiety.The author accepts that in certain cases distorted cognitions lead to an experience that is represented contra to reality. He suggests that in certain circumstances a cognitive therapist could help a patient to reappraise the world they find themselves in and by gathering evidence with the therapist, to challenge these distortions. So in depression, a patient sees themselves as worthless and their therapist suggests they gather evidence that helps them form a more balanced perspective. The cognition "I am worthless" is shown empirically to be a distortion. Whiting argues, correctly in my opinion, for the limitation of this approach. In doing so he argues against a growing psychological hegemony, one that sees itself as developing evidence-based practice that should be applied (on the back of national guidelines) to many presentations before or exclusively of others such as medication or alternative psychotherapeutic approaches.Whatever the outcome in the clinic, as opposed to the randomized controlled trials, many clinicians and health care managers are attracted to CBT because of its pragmatic, short-term, problem- and consumer-orientated nature. It has an approach tailored for most disorders and therefore fits very well within the organization of modern mental health services. With this background, nonclinical readers may more readily appreciate the potential target of Dr. Whiting's critique.Whiting suggests three examples where eliciting cognitions can at best be seen as secondary [End Page 247] to the problem in hand: First, where a drug (e.g., alcohol) or state (e.g., tiredness) directly causes an emotion; second, where an emotion causes a mistaken understanding of a situation; and third, where the representation is accurate but the response defective (e.g., the pedophile in his article, or more routinely a person particularly sensitive to anxiety). The phenomenology, before the prism of analysis, is that in all three cases the patients find themselves in an emotional state where any putative cognitive etiology is at best post hoc and at worst tautological. Furthermore, as the author states, in the cases where accurate representations elicit the wrong kinds of emotions, the question why cannot be answered by referring back to the person's representations.To answer the question of why someone is particularly sensitive to anxiety or gets aroused by children, Dr. Whiting points to several possibilities that all impact on treatment: First, the influence of noncognitive desires and emotions; second, physical contamination; third, an idiosyncratic or abnormal constitution; and fourth, a defective emotional acculturation. In all these cases, suggesting that the patient's problems will be resolved through altering eliciting cognitions seems illogical.The paper then preempts two criticisms from the cognitive approach. The first again rightly expands that, if a higher order evaluative level is proposed, this in no way answers a noncognitive critique. Either the higher level of evaluation is simply an unnecessary (or unpredictable) cognitive confirmation of a negative (or positive) representation, or the evaluation is a cognitive foil for an emotional reaction that is simply not cognitive; when someone says they are worthless they are merely giving voice to their depressed emotional state. Second, that retreating to a position where the cognitive approach is used to challenge distorted representations that are secondary to, and yet maintain, an inappropriate emotion may have a role, but does not mean that...

A recently popular formulation of the Higgs naturalness principle prohibits delicate cancellations between running renormalized Higgs mass parameters and EFT matching corrections, by contrast with the principle’s original formulation, which prohibits delicate cancellations between the bare Higgs mass parameter and its quantum corrections. While the need for this latter cancellation is sometimes viewed as unproblematic since bare parameters are thought by some to be divergent and unphysical, renormalized parameters are finite and measurable, and the need for delicate cancellations between the (...) renormalized Higgs mass parameter and EFT matching corrections is therefore considered by some to constitute a more salient formulation of the Higgs naturalness problem. Here, we argue that to the contrary, the need for fine tuning of the renormalized Higgs mass parameter is an eliminable, unphysical artifact of renormalization scheme, and that this severely weakens the grounds for regarding it as a problematic instance of fine tuning. In doing so, we highlight what we take to be a number of important conceptual lessons about the physical interpretation of model parameters in QFT. (shrink)

This review pertains to the book _Evolutionary Theology (Teologia ewolucyjna)_ written by Wojciech P. Grygiel and Damian Wąsek. The book presents a distinct and modern viewpoint on theology by offering a comprehensive analysis of the characteristics of theological language and utilizing it to reevaluate certain theological beliefs, such as the concept of original sin, within the framework of the ever-changing understanding of the Universe. This approach contributes significantly to the restoration of theology’s credibility in modern culture by bridging the gap (...) between science and theology. (shrink)

In this paper, the concept of structural information is presented. The mathematical foundation of the concept is put forward, and the nature of information encoded in a structure is studied. A method for calculating the amount of structural information is introduced. An application to the analysis of cognitive maps is also presented and discussed.

The way from the path integral to Feynman diagrams is sketched. The emphasis is put on the decrease of complexity in this process, from infinite-dimensional integrals down to the apparent simplicity of child’s play. On the other hand, also the subsequent increase in complexity when using Feynman diagrams to make realistic physical predictions is described, thus illustrating the dialectic between the simplicity and clarity of Feynman diagrams, and the complexity in their practical applications.

We examine physicists’ charge of ad hocness against the Higgs mechanism in the standard model of elementary particle physics. We argue that even though this charge never rested on a clear-cut and well-entrenched definition of “ad hoc”, it is based on conceptual and methodological assumptions and principles that are well-founded elements of the scientific practice of high-energy particle physics. We further evaluate the implications of the recent discovery of a Higgs-like particle at the CERN’s Large Hadron Collider for the charge (...) of ad hocness against the Higgs mechanism. (shrink)

Recent years have seen the appearance of many English-language hand books of logic and numerous monographs on topical discoveries in the foundations of mathematics. These publications on the foundations of mathematics as a whole are rather difficult for the beginners or refer the reader to other handbooks and various piecemeal contribu tions and also sometimes to largely conceived "mathematical fol klore" of unpublished results. As distinct from these, the present book is as easy as possible systematic exposition of the now (...) classical results in the foundations of mathematics. Hence the book may be useful especially for those readers who want to have all the proofs carried out in full and all the concepts explained in detail. In this sense the book is self-contained. The reader's ability to guess is not assumed, and the author's ambition was to reduce the use of such words as evident and obvious in proofs to a minimum. This is why the book, it is believed, may be helpful in teaching or learning the foundation of mathematics in those situations in which the student cannot refer to a parallel lecture on the subject. This is also the reason that I do not insert in the book the last results and the most modem and fashionable approaches to the subject, which does not enrich the essential knowledge in founda tions but can discourage the beginner by their abstract form.

During the global financial crisis of 2007–2009 and the currentCovid-19 debacle, central banks acted quickly, boldly, and effectively. The paper argues that they did so thanks to the lessons learned from the past financial crises, which provided them with opportunities to reconsider their previous beliefs. A case in point is the banking crisis in the United States during the Great Depression of the 1930s that taught central banks to act rapidly and decisively in order to prevent an initial liquidity crisis (...) from escalating into a solvency crisis leading to bankruptcies of banks with potentially disastrous consequences for the entire economy. The paper revisits the consequences of the currency crises of the 1990s, which transformed exchange rate regimes across the world: the EMS one of 1992–1993 that accelerated the launch of the euro, and the Asian one of 1997–1998 resulted in the proliferation of floating exchange rates in emerging economies.

The main aim of the present paper is to explain a nature of relationships exist between Nelson and Heyting algebras. In the realization, a topological duality theory of Heyting and Nelson algebras based on the topological duality theory of Priestley for bounded distributive lattices are applied. The general method of construction of spaces dual to Nelson algebras from a given dual space to Heyting algebra is described. The algebraic counterpart of this construction being a generalization of the Fidel-Vakarelov construction is (...) also given. These results are applied to compare the equational category N of Nelson algebras and some its subcategories with the equational category H of Heyting algebras. It is proved that the category N is topological over the category H. (shrink)

In this article, the author notes that Thomas Aquinas, in his brief work entitled De Ente et Essentia, proved that at the base of understanding the world, the human being, and God in particular, there is our understanding of being and its essence. When we make a small mistake at the beginning in our understanding of being and its essence, it will turn to be a big one in the end. And what is “at the end” of our knowledge is (...) the discovery of the First and Ultimate Cause of all things, known as: Ipsum Esse, God, the Absolute, The Most Perfect Substance, on whom everything depends, and who depends not on anything else. These present inquiries about the proper understanding of being and its essence are aimed at formulating proof of the necessity of existence of a Being that is the First Cause, and which, existing as Ipsum Esse, is the source and reason of existence of all beings. Without these inquiries, the proof itself would be incomprehensible, and more importantly it would be a purely a priori one. Furthermore, without the existential conception of being, which Thomas first formulated, one could not discover the First Cause which, as Ipsum Esse, is the source of the existence of every being. This issue seems to have escaped the attention of the author of the book Aquinas’s Way to God. The Proof in “De Ente et Essentia.”. (shrink)

This paper repudiates Manuel Vargas’s attempt to supplant the traditional moral influence theory of responsibility with his ‘agency cultivation model’. By focusing on fostering responsiveness to moral considerations, ACM purports to avoid the chief pitfalls of MIT. However, I contend that ACM is far less distinctive than it initially appears and so possesses all of MIT’s defects. I also assail Vargas’s counterfactual test for assessing whether a wrongdoer can respond to moral considerations. It is argued that the counterfactual test is (...) epistemically redundant because it can only be fleshed out once we have settled the issues it is supposed to resolve. Moreover, it tacitly inverts the relation between freedom and responsibility—we cannot attribute free will to wrongdoers unless we have already established their blameworthiness. The upshot of this is that enquiries into an agent’s freedom are irrelevant to the ethics of holding her responsible. (shrink)

We examine some extensions of the constructive propositional logic with strong negation in the setting of varieties of $\mathcal{N}$ -lattices. The main aim of the paper is to give a description of all pretabular, primitive and preprimitive varieties of $\mathcal{N}$ -lattices.

Natural Deduction Natural Deduction is a common name for the class of proof systems composed of simple and self-evident inference rules based upon methods of proof and traditional ways of reasoning that have been applied since antiquity in deductive practice. The first formal ND systems were independently constructed in the 1930s by G. Gentzen and S. Jaśkowski and … Continue reading Natural Deduction →.
