In his book Gabriele Lolli discusses the notion of proof, which is, according to him, the most important and at the same time the least studied aspect of mathematics. According to Lolli, a theorem is a conditional sentence of the form ‘if T then A’ such that A is a logical consequence of T, where A is a sentence and T is a sentence or a conjunction or set of sentences. Verifying that A is a consequence of T generally involves (...) considering infinitely many interpretations; so it is something which is impossible to do in finite terms. Proofs may serve as ‘shortcuts’ in this respect. A proof is defined by Lolli as any finite argument certifying that A is a consequence of T. A proof is a shortcut in the sense that it spares us considering infinitely many interpretations.The reason for such a very general definition of proof is Lolli's strong belief that mathematics is not a rigid system of explicit rules, but rather a set of tools; as a consequence, there is no prescription as to what a proof should or should not be. Actually, mathematics is historically situated and not timeless, and the history of mathematics is the …. (shrink)

_The purpose_ of the article is to comprehend the Husserlian model of constituting temporal modes through the ability of intentional "retentional-protentional" consciousness, as well as to clarify the possibility of interpreting its positions in the reconstruction of the concept of anthropic time. _Theoretical basis._ The theoretical framework of the research includes: 1) the interpretation of the phenomenological reflection of "time-consciousness" by E. Husserl in the context of solving the problem of phased-differentiation of this form of temporality; 2) the concept of (...) anthropic time (V. Khanzhy). _Originality._ For the first time in research literature, the possibilities of applying the ideas of Husserl to the reconstruction of the concept of anthropic time are considered through the interpretation of the phenomenological solution to the problem of temporality, proposed and specified in Husserl’s "time-consciousness" concept. _Conclusions._ The comprehension of the Husserlian model of intentionality of consciousness through the "grasping-from-now" and the constitution of phases of phenomenological time through the component of "exiting-from-now" showed that solving the problem of phased-differentiation of phenomenological time leads to the observation of the impossibility of isolating the modes of past, present, and future as self-sufficient and unconditional. More accurate indications, based on the constitutive intentionality of consciousness on the "grasping-from-now" phases of time (as conventional), are as follows: a) the abilities of retention and recollection are the foundation for the constitution of the past and its connections to the present; b) the perception establishes the basis for the phase of the present itself; c) the possibilities of protention and anticipation (as forms of imagination) constitute the future and its connections to the present. By the concept of retention, Husserl fixes a certain primary memory (the present "now" of a past interval), which enables retaining the past in the present. The category of recollection or secondary memory is used by the philosopher to refer to the self-sufficient reproduction of past experiences (without being joined to present perception). The fundamental difference between recollection and retention is that the former _re-_presents a temporal interval, grasping its content and reproducing it as it was in the past, while in the latter, the perceived duration is presented as a fragment of time that has just passed. According to the German philosopher, the "grasping" of the present phase is performed by perception. Through the constitutive intentionality of consciousness, perception synthesizes the results of primary-actual activity and retentional holding of duration. The second part of the article will present solutions to the following research tasks: 1) analysis of the possibilities of protention and anticipation in constituting the future and its connections with the present; 2) understanding the possibility of using interpreted forms of Husser’s ideas in reconstructing the concept of anthropic time.

The purpose. Critical social philosophy of education strives to provide a radical critique of existing models of education in the so-called Western models of democracy, creating progressive alternative models. In this context, the proposed integrative metatheory, which is based on classical and modern sources, concepts, aims for a comprehensive understanding and reconstruction of the phenomenon of education. One of the main tasks in the sphere of education’s democratization today, therefore, is to bring to education the results of restructuring and democratization (...) of the society, to reflect changes in conditions of life and thinking, experience and transformation of subjectivity in the context of the technological revolution and globalization. Methodology. The critical social theory, which developed in the framework of contemporary neo-Marxism, indicates the need for a thorough analysis of society, however, unlike other theoretical concepts and research programs in order to analyze not a fixation and a statement of the existing social givens. On the contrary, critical analysis of society involves the identification of existing antagonistic, alienating factors that distort public communication.The subject of social analysis is the whole sphere of human and non-human nature, which interacts a person depend on it, the whole system of relations between society and nature, society and man, which is covered by the historical practice of conscious – "praxis". The representative of "pure science" isn't the learning, research subject. He is a public a person, which is the totality of all social definitions included in society and its constituent individuals. For such a "total subject" Object of interest is not something external; on the contrary, the latter appears as a product of his own activity. The scientific novelty examines trends in educational institutions and models of globalizing society in the context of our particular relationship of education and society, man and the state, and processes. The research and systematic analysis of neoliberal reforms at the level of society in general and education in particular are conducted. It examines substantive, structural and functional characteristics of the concept of «critical social philosophy of education» in the context of institutional tendencies of social life, as well as forms and possibilities of its methodological application. It consider a model of «critical social philosophy of education», as embodied in the programs of social development and learning, which are primarily designed to teach people how to lead an independent and original research themselves, society and knowledge systems. However, it is proved that the models and programs should not be cut off from any individual and the collective system of moral and social values, theoretical and applied training, nor from further use of the acquired values, norms and skills in everyday life, science, or in production, sphere of all social institutions. Conclusions. Critical philosophical, educational, pedagogical-psychological surprisingly theory, its models and concepts seek to redefine public and private and the public mind. Based on these grounds, in the future, it allows philosophy of education to develop a more inclusive philosophical vision of education, to apply directly to the problems of democratization and changes in social relations in the direction of equality and social justice in the field of education. The point of view of socio-philosophical and philosophical-еducational, pedagogical-psychological, normative understanding and social critics also requires the use of active efforts in the reconstruuction of education and society, the social vision of what education and human life can be and what their specific limitations in existing societies.

Abstract In this chapter, we challenge the presupposed concept of innovation in the responsible innovation literature. As a first step, we raise several questions with regard to the possibility of ‘responsible’ innovation and point at several difficulties which undermine the supposedly responsible character of innovation processes, based on an analysis of the input, throughput and output of innovation processes. It becomes clear that the practical applicability of the concept of responsible innovation is highly problematic and that a more thorough inquiry (...) of the concept is required. As a second step, we analyze the concept of innovation which is self-evidently presupposed in current literature on responsible innovation. It becomes clear that innovation is self-evidently seen as (1) technological innovation, (2) is primarily perceived from an economic perspective, (3) is inherently good and (4) presupposes a symmetry between moral agents and moral addressees. By challenging this narrow and uncritical concept of innovation, we contribute to a second round of theorizing about the concept and provide a research agenda for future research in order to enhance a less naïve concept of responsible innovation.

For millennia, diagnosticians distinguished natural sadness that arose from social circumstances from depressive disorders that were disproportionate to their contexts. In 1980, the DSM-III transformed this tradition through equating depressive disorders with symptoms without regard to context. Nevertheless, it excluded grieving people without especially severe or enduring symptoms from diagnosis. Subsequently, considerable empirical research indicated that bereavement was not unique but a model for all stressor-maintained conditions. Yet, despite the evidence showing that the causes, prognoses, and optimal treatments for context-specific (...) depressions differ from those that aren’t, the DSM-5 removed the bereavement exclusion from the diagnostic criteria for major depression. This article considers the reasons behind this elimination and its implications for the research, labeling, and treatment of depression. (shrink)

The increasing demographic changes of populations in many countries require an approach for managing the complexity of sociocultural differences. Such an approach could help healthcare organizations to address healthcare disparities and inequities, and promote cultural safety for healthcare providers and patients alike. Almutairi's critical cultural competence (CCC) is a comprehensive approach that holds great promise for managing difficulties arising from sociocultural and linguistic issues during cross‐cultural interactions.CCChas addressed the limitations of many other cultural competence approaches that have been discussed in (...) the literature. Therefore, the purpose of this study is to define the construct ofCCCand the theoretical components of theCCC. (shrink)

In the latest reform of the National Health Service great emphasis has been placed on the achievement and maintenance of quality. Mechanisms for ensuring this are being set up under the general title of “clinical governance”. What is the meaning of this term? The metaphor behind the phrase is of navigation through stormy seas, but who guides the helmsman? Clinical ethics committees could have a part to play in these changes, provided their role is properly understood. Clinical governance is concerned (...) with management according to an agreed set of aims. The task of ethics committees is Socratic rather than managerial. They should ask fundamental questions about the ethical norms of the services provided and give critical appraisal of the moral character of institutional policies. If these tasks are carried out then governance may become a watchword rather than just another buzzword. (shrink)

Zusammenfassung Der Beitrag widmet sich der Entstehung des Faches Religionsgeschichte in Frankreich. Die Vorgeschichte zu diesem Prozess beginnt mit Benjamin Constants Religionsphilosophie der 1810–1820er Jahre, in der die lokalen und diachronen Veränderungen des allgemein menschlichen religiösen Gefühls als ein Schlüssel zur Religionsgeschichte verstanden wurden. Nach einer langen Pause wird das Thema des religiösen Gefühls in Albert Révilles liberaltheologischem Projekt wieder aktuell. Ausgehend von Schleiermachers Voraussetzungen hoffte Réville dadurch die Apologetik zu modernisieren wie auch den Weg zum theologischen Inklusivismus zu bahnen. (...) Sein Sohn Jean, ebenfalls Theologe, neutestamentlicher Forscher und Sentimentalist, arbeitete mit dem Vater zusammen an der Institutionalisierung des Faches Religionsgeschichte in Frankreich. Albert Réville leitete von 1886 bis zu seinem Tod 1906 die fünfte (religionswissenschaftliche) Sektion der École Pratique des Hautes Études, gleichzeitig war Jean Réville seit 1884 Herausgeber der Fachzeitschrift Revue de l’histoire des religions. Révilles theoretischer Standpunkt wurde von É. Durkheim und seinen Gleichgesinnten H. Hubert und M. Mauss, die die weitere weltanschauliche Säkularisierung förderten, nach 1898 stark kritisiert. Diese Serie von Erwiderungen zeigt die Kluft zwischen der Methodologie der (dem Ursprung nach) evangelischen Religionsgeschichte und der durkheimischen Religionssoziologie. (shrink)

We present a novel variant of decision making based on the mathematical theory of separable Hilbert spaces. This mathematical structure captures the effect of superposition of composite prospects, including many incorporated intentions, which allows us to describe a variety of interesting fallacies and anomalies that have been reported to particularize the decision making of real human beings. The theory characterizes entangled decision making, non-commutativity of subsequent decisions, and intention interference. We demonstrate how the violation of the Savage’s sure-thing principle, known (...) as the disjunction effect, can be explained quantitatively as a result of the interference of intentions, when making decisions under uncertainty. The disjunction effects, observed in experiments, are accurately predicted using a theorem on interference alternation that we derive, which connects aversion-to-uncertainty to the appearance of negative interference terms suppressing the probability of actions. The conjunction fallacy is also explained by the presence of the interference terms. A series of experiments are analyzed and shown to be in excellent agreement with a priori evaluation of interference effects. The conjunction fallacy is also shown to be a sufficient condition for the disjunction effect, and novel experiments testing the combined interplay between the two effects are suggested. (shrink)

Questions connected with the admissibility of rules of inference and the solvability of the substitution problem for modal and intuitionistic logic are considered in an algebraic framework. The main result is the decidability of the universal theory of the free modal algebra imageω extended in signature by adding constants for free generators. As corollaries we obtain: there exists an algorithm for the recognition of admissibility of rules with parameters in the modal system Grz, the substitution problem for Grz and for (...) the intuitionistic calculus H is decidable, intuitionistic propositional calculus H is decidable with respect to admissibility . A semantical criterion for the admissibility of rules of inference in Grz is given. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Matter and Mathematics: An Essentialist Account of the Laws of Nature by Andrew YOUNANDominic V. CassellaYOUNAN, Andrew. Matter and Mathematics: An Essentialist Account of the Laws of Nature. Washington, D.C.: The Catholic University of America Press, 2023. xii + 228 pp. Cloth, $75.00Andrew Younan’s work situates itself between two opposing philosophical accounts of the laws of nature. In one corner, there are the Humeans (or Nominalists); in the (...) other, the Anti-Humeans (or Platonists). The goal of the book is to find an explanation for the orderliness of the natural world that avoids falling into the difficulties of the two opposing philosophies. For example, the Humeans treat “events” as fundamental, and the laws of nature follow from these “events.” For the Humeans, reality is essentially random, with any order being something of our own contrivance. Whereas for the Anti-Humeans, the laws of nature are fundamental and are treated as causing events, turning the effect of necessity into the cause of material [End Page 166] characteristics. Looking to Aristotle and Thomas Aquinas, Younan proposes the recovery of a third option, the Essentialist position. This Essentialist position understands substances, that is, individual beings, as fundamental and all else (for example, events and laws of nature) follow from these individual beings. The thesis of the book, generally understood, is that Essentialism evades the critiques that the Humeans and Anti-Humeans put against one another while retaining what is right in each approach.The book is divided into two parts. The book’s first part deals with general objections and replies and is divided into three chapters. Chapters 1 and 2 address the two opposing accounts of nature mentioned, while chapter 3 argues for the benefits of recovering an Essentialist position. Chapter 1 examines the objection that Aristotelian natural philosophy is incompatible with modern science, an objection raised by Descartes. Chapter 2 addresses the objections of the Humeans, namely, that natural philosophy and, with it, causality and induction have been debunked. Chapter 3 looks at the fathers of quantum theory, specifically Heisenberg, and argues that a return to Aristotle’s understanding of nature would benefit the modern scientific project. The book’s second part is an argument for the Essentialist position and is divided into three chapters. Chapters 4 and 5 are the foundation for chapter 6. Chapter 4 is an abstractive account of mathematics, differing from Descartes and his conceptions, which draws on the texts of Aristotle and Aquinas’s Division and Methods. Chapter 5 situates necessity and its role in Aristotelian natural philosophy. Chapter 6 is the author’s attempt at defining what it is to be a law of nature.Younan argues that adopting an essentialist understanding of nature in a system where all knowledge begins in the senses has three significant “payoffs.” The first is that it avoids governance language, that is, it avoids making laws themselves causes of necessity; the second is that it avoids the assertion of a priori knowledge; the third is that it understands individual things as the fundamental primitives in nature, restoring the substance to its proper place as the thing that “stands under” accidental being.The book is concluded with an appendix that explores and rearticulates Thomas Aquinas’s fifth way under the consideration of everything the author had argued for in the book’s main text. Taking as established by the rest of the book that necessity and teleology go hand in hand, Younan argues for a creator God who establishes a universe freely but within certain parameters that follow upon being itself. Younan concludes, with Thomas Aquinas, that laws of nature are “ordinances of reason” that must come from a rational mind. To be as consistent as they are, the laws of nature must be promulgated by God, and they are discoverable within the nature of matter itself.Younan’s book often engages its interlocutors on the big-picture scale, frequently giving generalizations and not going into details to avoid getting bogged down in the weeds. The author is very aware of what he is doing. [End Page 167] It is appropriate since engaging the multiheaded hydra of the schools of thought that Younan... (shrink)

Although research into the biosemiotic mechanisms underlying the purposeful behavior of brainless living systems is extensive, researchers have not adequately described biosemiosis among neurons. As the conscious use of signs is well-covered by the various fields of semiotics, we focus on subconscious sign action. Subconscious semiotic habits, both functional and dysfunctional, may be created and reinforced in the brain not necessarily in a logical manner and not necessarily through repeated reinforcement. We review literature that suggests hypnosis may be effective in (...) changing subconscious dysfunctional habits, and we offer a biosemiotic framework for understanding these results. If it has been difficult to evaluate any psychological approach, including hypnosis, this may be because contemporary neuroscience lacks a theory of the sign. We argue that understanding the fluid nature of representation in biological organisms is prerequisite to understanding the nature of the subconscious and may lead to more effective of treatments for dysfunctional habits developed through personal experience or culture.

While specifications and verifications of concurrent systems employ Linear Temporal Logic , it is increasingly likely that logical consequence in image will be used in the description of computations and parallel reasoning. Our paper considers logical consequence in the standard image with temporal operations image and image . The prime result is an algorithm recognizing consecutions admissible in image, so we prove that image is decidable w.r.t. admissible inference rules. As a consequence we obtain algorithms verifying the validity of consecutions (...) in image and solving the satisfiability problem. We start by a simple reduction of logical consecutions of image to equivalent ones in the reduced normal form . Then we apply a semantic technique based on image-Kripke structures with formula definable subsets. This yields necessary and sufficient conditions for a consecution to be not admissible in image. These conditions lead to an algorithm which recognizes consecutions admissible in image by verifying the validity of consecutions in special finite Kripke structures of size square polynomial in reduced normal forms of the consecutions. As a consequence, this also solves the satisfiability problem for image. (shrink)

The paper aims to analyze three discussions pertaining to the artificial intelligence project that took place on both sides of the “Iron Curtain” since the 1960s: 1) E.V. Ilyenkov – D.I. Dubrovsky (USSR), 2) H. Dreyfus – computer scientists (USA), 3) H. Dreyfus – H. Collins (USA – UK). The authors observe the originality of the arguments of Soviet philosophers in comparison with the discussions in the US and UK. The basis for a comparative analysis of these discussions is the (...) typology of social intercourse paradigms, which assumes the existence of three fundamentally different views of humans as social beings: the information-instrumental, the existential-phenomenological, and the social-institutional paradigms. These views correlate with the ideas about humans within different theoretical structures examining artificial intelligence. The information-instrumental paradigm poses the problem of social intercourse regarding communication, material, and informational exchange (D.I. Dubrovsky, computer scientists). The social-institutional paradigm considers social intercourse as personification, actualization, and implementation of the structural characteristics of social relations (E.V. Ilyenkov). The existential-phenomenological paradigm characterizes social intercourse as the realization of the internal potency of a self-conscious individual (H. Dreyfus). The paper exposes that the theoretical and methodological foundations of the discussions under consideration are similar to the paradigmatic foundations of the analysis of social intercourse in social philosophy and social sciences. There are “two and a half floors” in the research of problems associated with the entry of artificial intelligence technologies into the everyday life of society: 1) philosophy, computer and cognitive sciences; 2) social sciences; 3) interdisciplinary research. A particular paradigmatic structure and a unique research problem characterize each of them. In conclusion, “new old questions” are highlighted that structure the field of contemporary social analytics for studying artificial intelligence and artificial sociality. (shrink)

The ethics of citation has attracted increased attention in recent discussions of research and publication ethics, fraud and plagiarism. Little attempt has been made, however, to situate specific citation misbehaviors in terms of broader ethical practices and principles. To investigate researchers’ perceptions of citation norms, we surveyed active US researchers receiving federal funding from the National Institutes of Health (NIH), the National Science Foundation (NSF), and the National Endowment for the Humanities (NEH). Participants (_n_ = 257) were asked about citation (...) norms they endorse (norm reports), the behaviors they perceive others to engage in (peer reports), and their own citation behaviors (self-reports). Our analyses showed that while considerable discrepancies exist between norm reports, peer reports and self-reports, respondents’ discipline has no significant effect on these. Participants indicated that their own practices and that of their peers falls short of the norms they endorse, but that their own behavior is much less ethically deficient than that of their peers. An exploratory factor analysis revealed that ethically questionable citation behaviors could be grouped usefully into three categories: strategic citations, neglectful citations, and blind citations. Contrary to our hypothesis, the survey showed that greater experience does not always result in better citation practices. A particularly divisive issue pertained to intentionally citing authors from underrepresented demographic groups for reasons of social justice, but broad support for this practice is lacking, although arts and humanities scholars are slightly more supportive. Most researchers view questionable citation practices as negatively affecting their disciplines. Our findings suggest the need for clearer articulations of the citation norms and improved guidance and training about citations. (shrink)

Aristotle's views on the fundamental nature of reality are usually taken to be inconsistent. The two main sources for these views are the Categories and the central books of the Metaphysics, particularly book Zeta. In the early theory of the Categories the basic entities of the world are concrete objects such as Socrates: Aristotle calls them 'primary substances'. But the later theory awards this title to the forms of concrete objects. Michael Wedin proposes a compatibilist solution to this long-standing puzzle, (...) arguing that Aristotle is engaged in quite different projects in the two works. The theory of Metaphysics Zeta is meant to explain central features of the standing doctrine of the Categories, and so presupposes the essential truth of the early theory. The Categories offers a theory of underlying ontological configurations, while book Zeta gives form the status of primary substance because it is primarily the form of a concrete object that explains its nature, and this form is the substance of the object. So when the late theory identifies primary substance with form, it appeals to an explanatory primacy that is quite distinct from the ontological primacy that dominates the Categories. Wedin's new interpretation thus allows us to see the two treatises as complementing each other: they are parts of a unified history of substance. (shrink)

Current models of cortical speech and language processing include multiple regions within the temporal lobe of both hemispheres. Human communication, by necessity, involves complex interactions between regions subserving speech and language processing with those involved in more general cognitive functions. To assess these interactions, we utilized an ecologically salient conversation-based approach. This approach mandates that we first clarify activity patterns at the earliest stages of cortical speech processing. Therefore, we examined high gamma (70-150 Hz) responses within the electrocorticogram (ECoG) recorded (...) simultaneously from Heschl’s gyrus (HG) and lateral surface of the superior temporal gyrus (STG). Subjects were neurosurgical patients undergoing evaluation for treatment of medically intractable epilepsy. They performed an expanded version of the Mini-mental state examination (MMSE), which included additional spelling, naming, and memory-based tasks. ECoG was recorded from HG and the STG using multicontact depth and subdural electrode arrays, respectively. Differences in high gamma activity during listening to the interviewer and the subject's self-generated verbal responses were quantified for each recording site and across sites within HG and STG. The expanded MMSE produced widespread activation in auditory cortex of both hemispheres. No significant difference was found between activity during listening to the interviewer's questions and the subject's answers in posteromedial HG (auditory core cortex). A different pattern was observed throughout anterolateral HG and posterior and middle portions of lateral STG (non-core auditory cortical areas), where activity was significantly greater during listening compared to speaking. No systematic task-specific differences in the degree of suppression during speaking relative to listening were found in posterior and middle STG. Individual sites could, however, exhibit task-related variability in the degree of suppression during speaking compared to listening. The current study demonstrates that ECoG recordings can be acquired in time-efficient dialog-based paradigms, permitting examination of language and cognition in an ecologically salient manner. The results obtained from auditory cortex serve as a foundation for future studies addressing patterns of activity beyond auditory cortex that subserve human communication. (shrink)
