Within Jean Paul Sartre’s atheistic program, he objected to Christian mysticism as a delusory desire for substantive being. I suggest that a Christian mystic might reply to Sartre’s attack by claiming that Sartre indeed grasps something right about the human condition but falls short of fully understanding what he grasps. Then I argue that the true basis of Sartre’s atheism is neither philosophical nor existentialist, but rather mystical. Sartre had an early mystical atheistic intuition that later developed into atheistic mystical (...) experience. Sartre experienced the nonexistence of God. (shrink)

I urge philosophers of religion to investigate far more vigorously than they have until now the acceptability of varied components of the world religions and their epistemological underpinnings. By evaluating "acceptability" I mean evaluation of truth, morality, spiritual efficacy and human flourishing, in fact, any value religious devotees might think significant to their religious lives. Secondly, I urge that philosophers of religion give more attention to what scholars have called the "esoteric" level of world religions, including components of strong ineffability, (...) weak ineffability, and an alleged perennial philosophy. All this should involve a cooperative effort between analytic, comparative, and feminist philosophy of religion. (shrink)

In what follows I offer an explanation for the evils in our world that should be a live option for theists who accept middle knowledge. My explanation depends on the possibility of a multiverse of radically different kinds of universes. Persons must pass through various universes, the sequence being chosen by God on an individual basis, until reaching God’s goal for them. Our universe is depicted as governed much by chance, and I give a justification, in light of my thesis, (...) for why God would have people pass through a universe of just such a sort. (shrink)

Philosophers have given much attention to belief and knowledge. Here I introduce an epistemic category close to but different from belief, that I call ‘ersatz’belief. Recognition of this category refines our catalogue of epistemic attitudes in an important way.

Pierre-Henri Castel provides a short but richly argued precis of his recently published two-volume 1,000-page masterwork on the history of obsessive-compulsive disorder. Having not read the as-yet-untranslated books, I write this commentary from Plato’s cave, trying to infer the reality of Castel’s analysis from expository shadows. I am unlikely to be more successful than Plato’s poor troglodytes, so I apologize ahead of time for any misunderstandings. Moreover, I cannot assess Castel’s detailed evidential case for his substantive theses.1 I thus focus (...) on some key philosophical issues that impinge on an area of my concern, the concept of mental disorder. Castel is a rare breed of French.. (shrink)

Science is a crowning glory of the human spirit and its applications remain our best hope for social progress. However, there are limitations to existing science and perhaps to any science. The general mind-body problem is known to be currently intractable and mysterious (8). This is one of many deep problems that are generally agreed to be beyond the present purview of Science, including many quantum phenomena, etc. However, all of these famous unsolved problems are either remote from everyday experience (...) (entanglement, dark matter) or are hard to even define sharply (phenomenology, consciousness, etc.). In this note, we will consider some computational problems in vision that arise every time that we open our eyes and yet are demonstrably inconsistent with current theories of neural computation. The focus will be on two famous related phenomena, known as the neural binding problem and the experience of a detailed stable visual world. I, among many others, have struggled with these issues for more than fifty years (1, 2, 3). Somewhat paradoxically, the continuing progress in scientific methods and knowledge reveals that these are both unsolvable within existing neuroscience. By considering some basic facts about how the brain processes image input, we will show that, under the standard theory, there are not nearly enough brain neurons to compute what we experience as vision. Inconsistencies like the ones shown here have had a profound effect on paradigm change in the sciences. More directly, the discussions below suggest possible new theories and experiments. (shrink)

I have spent over 50 years of dedicated research on this theme. These are my overall conclusions. I think that science-as-it-is has come to too-limited conclusions, largely because, by in large, they are using an outmoded, "Newtonian" model of reality, (echoing Penrose, D'Espagnat, Maturana). Twentieth century physics has changed that, and it is time to apply its results to the rest of our world picture. I contend that the "materialists", as exemplified by Dennett, are archeological artifacts! There still remains room (...) for the human mind and the human soul -and my book shows how! This book proposes an entirely new perspective and an actual solution to the problem based on modern biology,(Maturana), modern physics, (Bohr, D'Espagnat, Einstein), modern logic, (Quine) and modern philosophy, (Cassirer), but it is still firmly grounded in Realism. It's conclusion is that the existence of "mind" is a necessary consequence of realism. (shrink)

Employing the ideas of modern mathematics and biology, seen in the context of Ernst Cassirer's "Symbolic Forms, the author presents an entirely new and novel solution to the classical mind-brain problem. This is a "hard" book, I'm sorry, but it is the problem itself, and not me which has made it so. I say that Dennett, and, indeed, the whole of academia is wrong.

In "Ordinary Morality Implies Atheism" (2009), I argued that traditional theism threatens ordinary morality by relieving us of any moral obligation to prevent horrific suffering by innocent people even when we easily can. In the current issue of this journal, Jerome Gellman attempts to rescue that moral obligation from my charge that theism destroys it. In this reply, I argue that his attempted rescue fails.

In this paper, I critically analyse Jerome Gellman’s proposal that there existsa type of experience in which a subject experiences evil and perceives in this evil that there is no God. This a-religious experience gives prima facie support to the belief that there is no God. I show how accepting Gellman’s pro-posal allows us to go beyond the classical distinction between the intellectualand the emotional problem of evil. It also allows us to defend the rationality of some (...) atheists, who do not believe in God because they experienced evil, but do not know the relevants arguments from evil. I suggest that there are twoproblems with Gellman’s account. The first is that there are no clear criteria of identifying a given experience of evil as the perception of God’s non-existence. The second problem concerns the scope of Gellman’s proposal. It is possible that some experiences of evil, which lead people to the belief that there is no God, do not count as perceptions that there is no God. In case of beliefsformed on the basis of such experiences, one must therefore look for another,non-perceptual grounds for justifying such beliefs. (shrink)

Jean-Paul Sartre is rarely discussed in the philosophy of religion. In 2009, however, Jerome Gellman broke the silence, publishing an article in which he argued that the source of Sartre’s atheism was neither philosophical nor existential, but mystical. Drawing from several of Sartre’s works – including Being and Nothingness, Words, and a 1943 review entitled ‘A New Mystic’ – I argue that there are strong biographical and philosophical reasons to disagree with Gellman’s conclusion that Sartre was a (...) ‘mystical atheist’. Moreover, I question the likelihood of drawing any definitive conclusions regarding the sources of Sartre’s ambiguous atheism. (shrink)

Advances in behavioral and brain sciences have engendered wide ranging efforts to help understand consciousness. The target article suggests that abstract computational models are ill-advised. This commentary broadens the discussion to include mysteries of subjective experience that are inconsistent with current neuroscience. It also discusses progress being made through demystifying specific cases and pursuing evolutionary considerations.

This paper proposes a methodological strategy to investigate the question of the individuation of the senses both from a commonsensical and a scientific point of view. We start by discussing some traditional and recent criteria for distinguishing the senses and argue that none of them taken in isolation seems to be able to handle both points of views. We then pay close attention to the faculty of hearing which offers promising examples of the strategy we pursue of combining commonsense and (...) science. In particular, we argue in favour of a distinction between two kinds of modes of presentation associated with sound perception: a mechanical mode of presentation that makes sounds perceptible by other modalities than audition such as touch and a tonal mode of presentation that makes people conceive of sounds as the proper objects of auditory perception.

The objective of this study is to present a theoretical paper about a clinical issue. Our aim is to propose some clinical and semiological considerations for a psychopathological conception of psychopathy. We will discuss several major theoretical works dedicated to this nosographic entity. We will also examine a significant issue raised by Cooke et al., namely whether psychopathic functioning is consistently related to antisocial behavior. This theoretical essay is informed by clinical situations. The method applied a phenomenological psychopathology analysis to (...) the clinical material. We first compare Binswanger’s conception of mania with psychopathic functioning. Patients’ behavior is similar but there is a difference related to the dialectic between the ego and the alter ego. A patient with mania has a fundamental crisis of the ego, which a psychopath does not have. A second finding of our investigations concerns emotions and the adaptive dimension of the psychopathic disorder. An epistemological discussion of the concept of emotions reveals that psychopaths are competent in the management of emotional stimuli, which confers a psychological advantage upon them. (shrink)

The right temporo-parietal junction (rTPJ) has been associated with two apparently disparate functional roles: in attention and in social cognition. According to one account, the rTPJ initiates a “circuit-breaking” signal that interrupts ongoing attentional processes, effectively reorienting attention. It is argued this primary function of the rTPJ has been extended beyond attention, through a process of evolutionarily cooption, to play a role in social cognition. We propose an alternative account, according to which the capacity for social cognition depends on a (...) network which is both distinct from and in tension with brain areas involved in focused attention and target detection: the default mode network. Theory characterizing the rTPJ based on the area’s purported role in reorienting may be falsely guided by the co-occurrence of two distinct effects in contiguous regions: activation of the supramarginal gyrus (SMG), associated with its functional role in target detection; and the transient release, during spatial reorienting, of suppression of the angular gyrus (AG) associated with focused attention. Findings based on meta-analysis and resting functional connectivity are presented which support this alternative account. We find distinct regions, possessing anti-correlated patterns of resting connectivity, associated with social reasoning (AG) and target detection (SMG) at the rTPJ. The locus for reorienting was spatially intermediate between the AG and SMG and showed a pattern of connectivity with similarities to social reasoning and target detection seeds. These findings highlight a general methodological concern for brain imaging. Given evidence that certain tasks not only activate some areas but also suppress activity in other areas, it is suggested that researchers need to distinguish two distinct putative mechanisms, either of which may produce an increase in activity in a brain area: functional engagement in the task versus release of suppression.

The purpose of the article is to reveal the scientific approach that substantiates the impact of the creation of strategic alliances (SA) on the digital transformation of business and the development of their innovative power based on identified success factors. The aim was achieved using the following methods: abstract logic and typification (for classification of SA's success factors), generalization (to determine the peculiarities of SA's influence on their innovation development), analytical and ranking method (to determine the relationship between the dynamics (...) creating of SA and the degree of acceleration of digital transformation), expert evaluation (to determine the degree of influence of SA success factors by business areas). Implementing a business-integrated approach to understanding digital transformation will accelerate implementation of innovation and organizational change, identifies future prospects for market, customer and business relationships, highlighting the importance of researching the factors that ensure their success. An alternative vision of SA’s success factors is suggested, which are determined by the possibilities the organization of partnerships and organizational culture, integration of business sectors, compatibility of management goals, external relevance, obtaining synergies. Innovation is considered by the authors as an integration factor that reconciles all groups of SA success factors, giving them the necessary focus to solve business problems. The results of the study show that the creation of SA has a significant impact on accelerating and changes priority of digital transformation of business areas involved in strategic partnerships, and the impact of SA on the development of their innovation power is crucial.

Biological individuality is a notoriously thorny topic for biologists and philosophers of biology. In this paper we argue that biological individuality presents multiple, interconnected questions for biologists and philosophers that together form a problem agenda. Using a case study of an interdisciplinary research group in ecology, behavioral and evolutionary biology, we claim that a debate on biological individuality that seeks to account for diverse practices in the biological sciences should be broadened to include and give prominence to questions about uniqueness (...) and temporality. We show that broadening the problem agenda of biological individuality draws attention to underrecognized philosophical issues and discussions and thereby organizes and enriches the existing debate.

People are motivated by shared social values that, when held with moral conviction, can serve as compelling mandates capable of facilitating support for ideological violence. The current study examined this dark side of morality by identifying specific cognitive and neural mechanisms associated with beliefs about the appropriateness of sociopolitical violence, and determining the extent to which the engagement of these mechanisms was predicted by moral convictions. Participants reported their moral convictions about a variety of sociopolitical issues prior to undergoing functional (...) MRI scanning. During scanning, they were asked to evaluate the appropriateness of violent protests that were ostensibly congruent or incongruent with their views about sociopolitical issues. Complementary univariate and multivariate analytical strategies comparing neural responses to congruent and incongruent violence identified neural mechanisms implicated in processing salience and in the encoding of subjective value. As predicted, neuro-hemodynamic response was modulated parametrically by individuals’ beliefs about the appropriateness of congruent relative to incongruent sociopolitical violence in ventromedial prefrontal cortex, and by moral conviction in ventral striatum. Overall moral conviction was predicted by neural response to congruent relative to incongruent violence in amygdala. Together, these findings indicate that moral conviction about sociopolitical issues serves to increase their subjective value, overriding natural aversion to interpersonal harm. (shrink)

The evolution of Intelligent Tutoring System (ITS) is the result of the amount of research in the field of education and artificial intelligence in recent years. English is the third most common languages in the world and also is the internationally dominant in the telecommunications, science and trade, aviation, entertainment, radio and diplomatic language as most of the areas of work now taught in English. Therefore, the demand for learning English has increased. In this paper, we describe the design of (...) an Intelligent Tutoring System for teaching English language grammar to help students learn English grammar easily and smoothly. The system provides all topics of English grammar and generates a series of questions automatically for each topic for the students to solve. The system adapts with all the individual differences of students and begins gradually with students from easier to harder level. The intelligent tutoring system was given to a group of students of all age groups to try it and to see the impact of the system on students. The results showed a good satisfaction of the students toward the system. (shrink)

In his text, “The Question Concerning Technology”, Heidegger argues that modern mind is unaware of Being’s self-destining which determines Dasein’s relation to their own essence and that of other beings because it is in a delusion of being an ‘efficient cause’. A bluntness of this kind not only endangers human-freedom but also puts natural entities at the risk of losing their authenticity since the modern mode of production regards nature as a reserve that is constantly in the service of human-doings. (...) Accordingly, the discussion carried out in this article is, despite his criticism of the conception of ‘agency’ underlying western metaphysics, whether or not Heidegger overcomes the problem of anthropocentrism in his own philosophy.

The approach to the study the role of strategic alliances in the conditions of digital business transformations has been further developed in the article. In the course of a critical analysis of the content of scientific publications of modern scientists who studied the behavior, peculiarities of activity and the meaning of strategic alliances, it was established that the role of strategic alliances in the conditions of digital transformations does not disappear, but brings new advantages, requiring the maximization of returns from (...) more dynamic partnership relations, which requires more in-depth study of such benefits. Dynamics analysis of the number of concluded agreements in the field of strategic partnership in the period of 2014-2023 demonstrates their increase starting from 2017, which led to the activation of digital business transformations. In the course of research, it was determined that the role of strategic alliances in the conditions of digital business transformations is to ensure strategic flexibility under the conditions of continuity of digital transformations, improve competitive positions on the market, increase their innovativeness and efficiency, improve organizational stability and the ability of companies to learn, create opportunities for obtaining synergistic effect. It develops the ability of companies to proactively manage changes, contributes to the joint solution of strategic tasks and goals of partner companies, provides significantly greater opportunities for the development of innovative processes through the development and implementation of new methods and forms of work, new solutions in economic sectors, innovations in management, contributes to survival in market competitive environment and is an important competitive imperative to ensure overall long-term digital transformation.

Philosophy of immunology is a subfield of philosophy of biology dealing with ontological and epistemological issues related to the studies of the immune system. While speculative investigations and abstract analyses have always been part of immune theorizing, until recently philosophers have largely ignored immunology. Yet the implications for understanding the philosophical basis of organismal functions framed by immunity offer new perspectives on fundamental questions of biology and medicine. Developed in the context of history of medicine, theoretical biology, and medical anthropology, (...) philosophy of immunology differs from these related branches of study in its focus on traditional philosophical questions concerning identity, individuality, ecology, cognition, scientific methodology and theory construction. This broad agenda derives from immunology’s multifaceted research program that has developed from its initial clinical challenges of host defense, transplantation, autoimmunity, tumor immunology, and allergy. In addition to these well-established research areas, immunity is now understood to play a central role in other physiological functions, development, ecology, and evolutionary mechanics. Holding together these diverse domains of inquiry lie philosophical commitments oriented by organismal identity. In this regard, pertinent issues are raised concerning cognition (organization of immune perception and information processing), the character of individuality (framed by the ecological context of immune-mediated assimilation and rejection), and the dynamics of complex systems (understood as holistic systems biology). Indeed, immunology, in the context of cognitive science, evolutionary biology, environmental sciences, and development provides multi-focal perspectives for philosophy of science. (shrink)

To clarify the proper role of values in science, focusing on controversial expert responses to Covid-19, this article examines the status of (in)convenient hypotheses. Polarizing cases like health experts downplaying mask efficacy to save resources for healthcare workers, or scientists dismissing “accidental lab leak” hypotheses in view of potential xenophobia, plausibly involve modifying evidential standards for (in)convenient claims. Societies could accept that scientists handle (in)convenient claims just like nonscientists, and give experts less political power. Or societies could hold scientists to (...) a higher bar, by expecting them not to modify evidential standards to avoid costs only incidentally tied to error. (shrink)

The Swiss psychologist Jean Piaget contends that children below the age of 12 see no necessity for the logical law of non-contradiction. I argue this view is problematic. First of all, Piaget's dialogues with children which are considered supportive of this position are not clearly so. Secondly, Piaget underestimates the necessary nature of following the logical law of non-contradiction in everyday discourse. The mere possibility of saying something significant and informative at all presupposes that the law of non-contradiction is enforced.

In her Idea of Perfection, Ms. Murdoch criticizes what she takes to be an existentialist conception of ethics. This conception is not, however, existentialist, either in the sense in which Sartre characterized it, or any of those other existentialists from Dostoyevsky onwards. Whether her alternative ethic is better or worse than that of the existentialist, I do not know; but the one is not in contrast to the other.

In contemporary scholarship, it is readily assumed that Nietzsche’s Eternal Recurrence either does or does not overcome the ‘problem of nihilism’. This exclusive disjunction, however, is false. It has arisen out of the poor exegesis that Eternal Recurrence is meant to overcome nihilism and, if it does not, then this can be considered a shortcoming of Nietzsche’s philosophic enterprise. But Eternal Recurrence only overcomes what you want it to: if you do not want to overcome nihilism but embrace it, then (...) Eternal Recurrence does not overcome nihilism, but this is in no way its failure. (shrink)

The article is aimed at studying environmental responsibility of multinational enterprises in electronics and IT sectors. The main aspects of environmental policy of global business enterprises have been systematized, their characteristics for such high-tech market leaders as Alphabet Inc, IBM and Intel Corporation have been given. Corporate policies have been analyzed and compared in three aspects of environmental activity of the companies selected for this study: waste recycling, energy use and environmental impact. The results of the analysis of eco-responsible companies’ (...) practices show that each company forms management style and tools by implementing environmental responsibility, but none of them has managed to hold higher positions in the ranking of business environmental responsibility. Reserves for activating eco-oriented companies’ policy in IT sector have been identified. (shrink)

Intermediate phenomena of reality present particular characteristics of systemic self-organization, multilevel interrelations, recursivity, emergence of new «objects» with properties different from those of the elements that form them, and evolutionary dynamics, that probably need the formulation of new theoretical concepts and different paradigm principles. The sciences or perspectives of complexity, or the «complex» thinking, try to respond adequately to this complexity of reality. This approach adopts a multidimensional, integrated and dynamic view of reality: the world is made up of overlapping (...) levels of different elements which produce new properties or new organizations at higher levels. If we conceive what we call languages as simple and decontextualized objects, we can understand some of the more mechanical aspects but we will ignore their conditions of existence, functionality, maintenance, variation, change and extinction.

In this book, Ilhan Inan questions the classical definition of curiosity as _a desire to know._ Working in an area where epistemology and philosophy of language overlap, Inan forges a link between our ability to become aware of our ignorance and our linguistic aptitude to construct terms referring to things unknown. The book introduces the notion of inostensible reference. Ilhan connects this notion to related concepts in philosophy of language: knowledge by acquaintance and knowledge by description; the referential and the (...) attributive uses of definite descriptions; the _de re/de dicto_ distinction; and Kripke’s distinction between rigid and accidental designators. Continuing with a discussion of the conditions for curiosity and its satisfaction, Inan argues that the learning process—starting in curiosity and ending in knowledge—is always an effort to transform our inostensible terms into ostensible ones. A contextual account is adopted for the satisfaction of curiosity. It then discusses the conditions of successful reference to the object of curiosity and its presuppositions. The book concludes with a discussion on the limits of curiosity and its satisfaction. (shrink)

In this paper I consider recent discussions within the representationalist theories of phenomenal consciousness, in particular, the discussions between first order representationalism (FOR) and higher order representationalism (HOR). I aim to show that either there is only a terminological dispute between them or, if the discussion is not simply terminological, then HOR is based on a misunderstanding of the phenomena that a theory of phenomenal consciousness should explain. First, I argue that we can defend first order representationalism from Carruthers' attacks (...) and ignore higher order thoughts in our account of phenomenal consciousness. Then I offer a diagnostic of Carruthers' misunderstanding. In the last section I consider further reasons to include mindreading abilities in an explanation of phenomenal consciousness. (shrink)
