Introducing the thought of philosopher and theologian Jean-Yves Lacoste, this book provides an overview spanning Lacoste's earliest works on sacramentality to his latest work Etre en Danger in which Lacoste opens up the liturgical experience onto a spiritual experience of life. Schriijvers unfolds the logic of what Lacoste calls 'the liturgical experience' from its violent variety in Expérience et Absolu to the logic of love and love's possibility as it is developed in the later works. Throughout the book, the focus (...) is on Lacoste's dialogue with Heidegger and through this his attempt to widen the scope of phenomenology to include the phenomenality of the divine. (shrink)

At one point in We will never have been modern Latour notes that his thinking is a “challenge to philosophy”. This article argues that Latour's challenge lies in his repeated claim that his ontology makes us able to think again about the “passing of time”. If this is indeed the case then, this essay looks to Martin Heidegger to think of the question of temporality and ontology. This essay will in effect find that on a deeper level Latour repeats crucial (...) Heideggerian insights with regard to the ontological difference between being and beings. Yet on other points too Heidegger's impact is notable: for Heidegger too, something has gone wary with modernity and our modern constitution. Here too Latour's metaphors point in a rather Heideggerian direction, for the “invisible” modern constitution has become “visible” in certain ontic events—Latour notes the end of communism. This recalls Heidegger's critique of metaphysics. The article will then focus on Latour's distinction between delegation and what is being delegated, a distinction that pervades the conclusion of his 1991 book. Latour thus introduces a difference between delegation and what is being delegated. How not to recognize a duplicate of Heidegger's ontological difference? And, once recognized, what does this mean for our thinking of being and the thinking of the event of world which has been delegated to us? (shrink)

This article discusses the political economy of AI capitalism. It considers AI as a General Purpose Technology and argues we need to investigate the power concentration of Big Tech. AI capitalism is characterised by the commodification of data, data extraction and a concentration in hiring of AI talent and compute capacity. This is behind Big Tech’s unstoppable drive for growth, which leads to monopolisation and enclosure under the winner takes all principle. If we consider AI as a GPT—technologies that alter (...) society’s economic and social structures—we need to come up with alternatives in terms of ownership and governance. The commons is proposed as an alternative for thinking about how to organise AI development and how to distribute the value that can be derived from it. Using the commons framework is also a way of giving society a more prominent role in the debate about what we expect from AI and how we should approach it. (shrink)

Jean-Luc Nancy’s Deconstruction of Christianity views the current crisis of globalization as a mutation of our Christian culture and heritage. After outlining the basic premises of Nancy’s philosophy, this article situates Jacques Derrida’s critique of Nancy in his groundbreaking On Touching: whereas Nancy sees contemporary culture as a rupture (or indeed mutation) with the former Christian culture, Derrida argues that we are still dealing with the remnants and relics of precisely culture and are at best witnessing a metamorphosis of this (...) culture. This dialogue between Nancy and Derrida allows us to assess the critique of metaphysics in both thinkers. (shrink)

The prime purpose of this paper is, first, to restore to discourse-bound occasion sentences their rightful central place in semantics and secondly, taking these as the basic propositional elements in the logical analysis of language, to contribute to the development of an adequate logic of occasion sentences and a mathematical (Boolean) foundation for such a logic, thus preparing the ground for more adequate semantic, logical and mathematical foundations of the study of natural language. Some of the insights elaborated in this (...) paper have appeared in the literature over the past thirty years, and a number of new developments have resulted from them. The present paper aims at providing an integrated conceptual basis for this new development in semantics. In Section 1 it is argued that the reduction by translation of occasion sentences to eternal sentences, as proposed by Russell and Quine, is semantically and thus logically inadequate. Natural language is a system of occasion sentences, eternal sentences being merely boundary cases. The logic has fewer tasks than is standardly assumed, as it excludes semantic calculi, which depend crucially on information supplied by cognition and context and thus belong to cognitive psychology rather than to logic. For sentences to express a proposition and thus be interpretable and informative, they must first be properly anchored in context. A proposition has a truth value when it is, moreover, properly keyed in the world, i.e. is about a situation in the world. Section 2 deals with the logical properties of natural language. It argues that presuppositional phenomena require trivalence and presents the trivalent logic ${\rm PPC}_{3}$ , with two kinds of falsity and two negations. It introduces the notion of Σ-space for a sentence A (or / A /, the set of situations in which A is true) as the basis of logical model theory, and the notion of / ${\bf P}^{A}$ / (the Σ-space of the presuppositions of A), functioning as a 'private' subuniverse for / A /. The trivalent Kleene calculus is reinterpreted as a logical account of vagueness, rather than of presupposition. ${\rm PPC}_{3}$ and the Kleene calculus are refinements of standard bivalent logic and can be combined into one logical system. In Section 3 the adequacy of ${\rm PPC}_{3}$ as a truth-functional model of presupposition is considered more closely and given a Boolean foundation. In a noncompositional extended Boolean algebra, three operators are defined: $1_{a}$ for the conjoined presuppositions of a, ã for the complement of a within $1_{a}$ , and â for the complement of $1_{a}$ within Boolean 1. The logical properties of this extended Boolean algebra are axiomatically defined and proved for all possible models. Proofs are provided of the consistency and the completeness of the system. Section 4 is a provisional exploration of the possibility of using the results obtained for a new discourse-dependent account of the logic of modalities in natural language. The overall result is a modified and refined logical and model-theoretic machinery, which takes into account both the discourse-dependency of natural language sentences and the necessity of selecting a key in the world before a truth value can be assigned.

A contemporary philosophy of religion that offers a phenomenology of love. What is to be done at the end of metaphysics? Joeri Schrijvers’s contemporary philosophy of religion takes up this question, originally posed by Reiner Schürmann and central to continental philosophy. The book navigates the work of thinkers who have addressed such metaphysical concerns, including Martin Heidegger, Emmanuel Levinas, Jean-Luc Nancy, Jean-Luc Marion, Peter Sloterdijk, Ludwig Binswanger, Jacques Derrida, and more recently John D. Caputo, Mary-Jane Rubenstein, and Martin Hägglund. Notably, (...) Schrijvers engages both those who would deconstruct Christianity and those who remain within this tradition, offering an option that is “between:” between Christianity and atheism, between progressive and conservative, between faith and belief. Ultimately, Schrijvers confronts the end of metaphysics with a phenomenology of love and community, arguing for the radical primacy of togetherness. “Joeri Schrijvers’s book is a tour de force, ranging over a wide spectrum of contemporary thinkers in order to negotiate the distance between religion and religionlessness, God and Godlessness, ontotheology and its overcoming. The result is a nuanced and careful study that repays close study.” — John D. Caputo, Syracuse University “Among the many lusters of Joeri Schrijvers’s Between Faith and Belief is a beautiful recovery of Ludwig Binswanger’s phenomenology of love. Discussion of postmetaphysical theology is arid without philosophically informed and creative talk of love, and Binswanger’s is a voice that has been missing from the conversation for far too long. To put Binswanger into dialogue with Caputo and Nancy, in particular, is at once fascinating and nourishing.” — Kevin Hart, University of Virginia. (shrink)

This is a commentary piece on Marco Pavanini's article ' ‘Multistability and Derrida’s Différance: Investigating the Relations Between Postphenomenology and Stiegler’s General Organology' in which I critically extend upon his comparative analysis of postphenomenology''s notion of multistability and Stiegler's conception of organology, focusing in particular on the pharmacological nature of Stiegler's organology and the latter's most recent re-interpretation of it in terms of entropy and negentropy. Among other things I show, and both are more intended as additions than criticisms with (...) respect to Pavanini’s very helpful comparison, that the most important concern for Stiegler in theorizing technology is the fact that the transductive relations between the three organ systems distinguished in his pharmaco-organology of technology open up affective or libidinal circuits between these systems, i.e., circuits either of desire or drive depending on the way the pharmakon is adopted or not, and that these circuits are fundamentally noetic circuits vulnerable to denoetization; and that these libidinal-noetic circuits as conditioned by technology should be interpreted in terms of entropy and negentropy. Both insights are lacking in postphenomenology, which generally fails to consider the irreducibly destitutive character of all technology, rightfully emphasized by Pavanini, since it lacks a genuine pharmacological awareness.

This paper investigates the impact of negative screening on the investment universe as well as on financial performance. We come up with a novel identification process and as such depart from mainstream socially responsible investing literature by concentrating on individual firms’ conduct and by studying a much wider range of issues. Firstly, we study the size and financial performance of fourteen potentially controversial issues: abortion, adult entertainment, alcohol, animal testing, contraceptives, controversial weapons, fur, gambling, genetic engineering, meat, nuclear power, pork, (...) stem cells, and tobacco. We investigate an international sample of more than 1,600 stocks for more than twenty years. We then analyze the impact of applying negative screens to a market portfolio. Our findings suggest that the choice for negative screening strategies does matter for the size of the investment universe as well as for risk-adjusted return performance. Investing in controversial stocks in many cases results in additional risk-adjusted returns, whereas excluding them may reduce financial performance. These findings suggest that there are opportunity costs to negative screening. (shrink)

In this article, we discuss the development of the concept of a ‘law’ (of nature) in the work of the Dutch natural philosopher and experimenter Petrus van Musschenbroek (1692–1761). Since Van Musschenbroek is commonly described as one of the first ‘Newtonians’ on the Continent in the secondary literature, we focus more specifically on its relation to Newton’s views on this issue. Although he was certainly indebted to Newton for his thinking on laws (of nature), Van Musschenbroek’s views can be seen (...) to diverge from Newton’s on crucial points. We show, moreover, how his thinking on laws of nature was shaped by both international and local factors. We start with a brief discussion of Newton’s concept of ‘laws of nature’ in order to set the stage for Van Musschenbroek’s. We then document the development of Van Musschenbroek’s views on laws of nature in chronological order. We demonstrate how his thinking on laws of nature was tied to institutional, theological and scientific factors. We conclude by pointing to the broader significance of this case study for our understanding of the development of the concept ‘law of nature’ during the eighteenth century. (shrink)

We generalize the modal interpretation of quantum mechanics so that it may be applied to composite systems represented by arbitrary density operators. We discuss the interpretation these density operators receive and relate this to the discussion about the interpretation of proper and improper mixtures in the standard interpretation.

One of the older questions in the debate about Corporate Social Responsibility (CSR) is whether it is worthwhile for organizations to pay attention to societal demands. This debate was emotionally, normatively, and ideologically loaded. Up to the present, this question has been an important trigger for empirical research in CSR. However, the answer to the question has apparently not been found yet, at least that is what many researchers state. This apparent ambivalence in CSR consequences invites a literature study that (...) can clarify the debate and allow for the drawing of conclusions. The results of the literature study performed here reveal that there is indeed clear empirical evidence for a positive correlation between corporate social and financial performance. Voices that state the opposite refer to out-dated material. Since the beginnings of the CSR debate, societies have changed. We can therefore clearly state that, for the present Western society, “Good Ethics is Good Business.”. (shrink)

In this dialogue with Yuk Hui, Pieter Lemmens explains the discipline called philosophy of technology and gives a concise overview of the most important contemporary approaches within this field. He also offers a critical evaluation of what are probably the two most salient characteristics of contemporary philosophy of technology, the so-called “empirical turn” and the “ethical turn,” which are deeply related and partly reflect the discipline’s on-going alignment with the global neoliberal agenda of exclusively profit-driven technological innovation. He also (...) critically reflects on recent developments in the molecular and informational life sciences such as genomics, metabolomics, bioinformatics and synthetic biology. (shrink)

In this reply I try to show that, contrary to Milberry’s apparent assertion, the general intellect of the multitude does not have the explanatory robustness she accredits to it. Digital network technologies are currently overwhelmingly effective in proletarianizing and disempowering the cognitariat and only an active technopolitics of deproletarianization could reverse this hegemonic situation. In my response to Verbeek, I attempt to correct his misinterpretation of the Stieglerian approach as being dialectical in nature and show that, far from reinstating the (...) humanist dichotomy between human beings and technologies, my analysis assumes their original, albeit fundamentally ambiguous and even ‘uncanny’ [unheimlich] interconnection. I conclude with pointing out some implications of this view for a ‘really realistic’ political theory of technology. (shrink)

This article discusses the final volume of Heidegger’s Gesamtausgabe. It does so by contextualizing its main themes, that is, by relating it to other writings of Heidegger of roughly the same period. Three such themes can be discovered in Heidegger’s “final” writing: a discussion of the nature of phenomenology, the abandonment of the ontological difference and the relation between the thought of being and the discipline of theology. The essay concludes with a comparison of Heidegger’s thinking of Ereignis to how (...) theology configured the relation between God and the human being, so arguing that Heidegger seemed more indebted to the tradition of theology that he at times could acknowledge.

‘The art of living with ICTs ’ today not only means finding new ways to cope, interact and create new lifestyles on the basis of the new digital technologies individually, as ‘consumer-citizens’. It also means inventing new modes of living, producing and, not in the least place, struggling collectively, as workers and producers. As the so-called digital revolution unfolds in the context of a neoliberal cognitive and consumerist capitalism, its ‘innovations’ are predominantly employed to modulate and control both production processes (...) and consumer behavior in view of the overall goal of extracting surplus value. Today, the digital networks overwhelmingly destroy social autonomy, instead engendering increasing social heteronomy and proletarianization. Yet it is these very networks themselves, as technical pharmaka in the sense of French ‘technophilosopher’ Bernard Stiegler, that can be employed as no other to struggle against this tendency. This paper briefly explores this possibility by reflecting upon current diagnoses of our ‘technological situation’ by some exemplary post-operaist Marxists from a Stieglerian, pharmacological perspective.

This article aims to be a confrontation with Nancy's 'deconstruction of Christianity.' Its arguments are instructed by Derrida's thesis in his On Touching—Jean-Luc Nancy , in which he speaks of the 'destructive effects' of Nancy's own thinking. One such effect is, according to Derrida, Nancy's complicity with some form of metaphysical thinking. The conclusion of this article therefore aims to expound on just what sort of metaphysics returns in Nancy's work and proposes a more viable—and phenomenological—option with regard to the (...) question of what is to be done with the relics of the Christian tradition through forging an opening towards Levinas' and Merleau-Ponty's philosophies.

This presentation offers a short overview of the basic insights of Jean-Yves Lacoste’s latest book La phénoménalité de Dieu. Apart from this, this essay seeks to establish some links with Lacoste’s earlier work.

This book explores Caputo's proposal for a radical theology of our time. Philosophers and theologians from within Europe respond to Caputo's attempt to configure a less rigid, less dogmatic form of religion. These scholars, in turn, receive responses by Caputo, thereby strengthening the development of radical theology in Europe and abroad.

Conceiving new technologies as social experiments is a means to discuss responsible deployment of technologies that may have unknown and potentially harmful side-effects. Thus far, the uncertain outcomes addressed in the paradigm of new technologies as social experiments have been mostly safety-related, meaning that potential harm is caused by the design plus accidental events in the environment. In some domains, such as cyberspace, adversarial agents may be at least as important when it comes to undesirable effects of deployed technologies. In (...) such cases, conditions for responsible experimentation may need to be implemented differently, as attackers behave strategically rather than probabilistically. In this contribution, we outline how adversarial aspects are already taken into account in technology deployment in the field of cyber security, and what the paradigm of new technologies as social experiments can learn from this. In particular, we show the importance of adversarial roles in social experiments with new technologies. (shrink)

Evolutionary psychiatrists invariably consider schizophrenia to be a paradox: how come natural selection has not yet eliminated the infamous ‘genes for schizophrenia’ if the disorder simply crushes the reproductive success of its carriers, if it has been around for thousands of years already, and if it has a uniform prevalence throughout the world? Usually, the answer is that the schizophrenic genotype is subject to some kind of balancing selection: the benefits it confers would then outbalance the obvious damage it does. (...) In this paper, however, I will show that the assumptions underlying such evolutionary accounts of schizophrenia are at least implausible, and sometimes even erroneous. First of all, I will examine some factual assumptions, in particular about schizophrenia’s impact on reproductive success, its genetics, its history, and its epidemiology. Secondly, I will take a critical look at a major philosophical assumption in evolutionary psychiatric explanations of schizophrenia. Indeed, evolutionary psychiatrists take it for granted that schizophrenia is a natural kind, i.e. a bounded and objectively real entity with discrete biological causes. My refutation of this natural kind view suggests that schizophrenia is in fact a reified umbrella concept, covering a heterogeneous group of disorders. Therefore, schizophrenia, as we now know it, simply doesn’t have an evolutionary history. (shrink)

This book is about how to understand quantum mechanics by means of a modal interpretation. Modal interpretations provide a general framework within which quantum mechanics can be considered as a theory that describes reality in terms of physical systems possessing definite properties. Quantum mechanics is standardly understood to be a theory about probabilities with which measurements have outcomes. Modal interpretations are relatively new attempts to present quantum mechanics as a theory which, like other physical theories, describes an observer-independent reality. In (...) this book, Pieter Vermaas summarises the results of this work. The book will be of great value to undergraduates, graduate students and researchers in philosophy of science, and physics departments with an interest in learning about modal interpretations of quantum mechanics.

Dr Seuren's study deals with the problem of presenting an adequate model of grammatical description. The model he proposes conforms in its main outlines to the transformational generative grammar established by Chomsky, but differs in important respects. These mainly affect that part of Chomsky's syntactic component known as the 'base', which generates basic or 'deep' structures. In the model of the base proposed here two main constituents are distinguished for every deep structure representation of a sentence, vis-a-vis the operators and (...) the nucleus. The deep structure of a sentence is thus seen to be very similar to the logical structure of a proposition. The arguments given in support of this analysis are based on mainly on considerations of simplicity and semantic adequacy. (shrink)

According to Leininger, presentists and growing blockers cannot explain why past and present regularities persist in the future. In order to do so, they would have to appeal to enforcers, such as causation, laws or dispositions. But in a world with no future, these enforcers are powerless and cannot guarantee future regularity. I disagree and argue that Leininger’s coordination problem can be met by distinguishing type- from token-level necessitation. Whereas token-level necessitation is cross-temporal and subject to Leininger’s coordination problem, type-level (...) necessitation is atemporal and immune to the coordination problem. For this solution to work, though, type-level necessitation must be ontologically prior to token-level necessitation. This forces us to adopt a Platonist position according to which universals are transcendent, and not immanent. (shrink)

Since Mendeleev’s discovery in 1869, the periodic table has figured as the ultimate paper tool in chemical research. It has proved to be a vital research instrument in the arsenal of the chemical community. No chemistry textbook, lecture theatre or scientific laboratory is complete without a copy of the periodic table of the elements. -/- This however, should not necessarily imply that the periodic table has never had to contend with problems. In this thesis, the history of the accommodation of (...) the rare-earth elements in the periodic table will be addressed. When Mendeleev published his periodic table in 1869, the rare earths already constituted a major obstacle. Mendeleev was able to include only four members of the rare earths and he experienced great difficulties in positioning these elements. Question marks and wrong atomic weights reigned in the last rows of Mendeleev’s system. -/- This problematic accommodation quickly grew into one of the most serious threats for the periodic law. For over fifty years, chemists continually struggled with the placement of these maddeningly similar elements. As a consequence, a lot of chemists started to question the validity of the periodic law, but others took it as a sign that the concept of a chemical element had to be reconsidered. As a result, this work intends to retrace the mutual influence of the philosophical ideas about the nature of chemical elements and the development of the periodic table from its inception in 1869 to the discovery of Moseley’s law in 1913 and Bohr’s publication of his landmark paper On the Constitution of Atoms and Molecules. -/- The aim of this thesis is to show how, on the one hand, the periodic table (as a research instrument) helped in reformulating the contemporary ideas about chemical elements, and how it aided in developing a new research program in order to resolve the rare earth crisis. On the other hand, the question will be taken up to what extent Crookes’ evolutionary ideas about meta elements helped in saving the periodic table from a severe downfall by solving the gnawing problem of the rare-earth elements. In particular, this work will also focus on the investigations of the Czech chemist, Bohuslav Brauner. It will be shown how Brauner, under the influence of Crookes’ ideas, was led to his formulation of the Asteroid Hypothesis, according to which all the rare-earth elements should be placed in a single case of the periodic table.

La teoría democrática rara vez se ajusta a las prácticas democráticas y las fluctuaciones de la opinión pública rara vez coincide con la cobertura de ese mismo actor político en los medios de comunicación.

he 4th Industrial Revolution introduced a highly automated and connected business environment. Nevertheless, many organizations are reeling in the wake of the speed and severity of the COVID-19 pandemic's impact, catching many unawares, and placing their sustainability in question. Given the connectedness promulgated by the 4th Industrial Revolution, one might expect organizational resilience to be a given - only time will tell whether this was the case. This article considers the concept of cybernetics as contributing to systems-thinking, which may enable (...) resilience strategies to come to fruition. Cybernetics is a goal-driven approach in which constant feedback is analyzed and applied in correcting the current course. We reflect on the roots and principles of the cybernetic concept, developing it into a management cybernetics concept. We take a non-technological approach in acknowledging organizations as systems. Management theories such as stakeholder and stewardship theories are systems components that can play a crucial role in effectively communicating management information within the cybernetic loop. We conclude that an integrative and cooperative relationship with legitimate stakeholders can play an essential role in an organization's preparedness. (shrink)

This paper outlines a multi-agent architecture for regulated information exchange of crime investigation data between police forces. Interactions between police officers about information exchange are analysed as negotiation dialogues with embedded persuasion dialogues. An architecture is then proposed consisting of two agents, a requesting agent and a responding agent, and a communication language and protocol with which these agents can interact to promote optimal information exchange while respecting the law. Finally, dialogue policies are defined for the individual agents, specifying their (...) behaviour within a negotiation. Essentially, when deciding to accept or reject an offer or to make a counteroffer, an agent first determines whether it is obligatory or permitted to perform the actions specified in the offer. If permitted but not obligatory, the agent next determines whether it is in his interest to accept the offer. (shrink)

Ausgangspunkt der Betrachtung von Aristoteles’ Ansichten zur Ontologie mathematischer Gegenstände ist die Sichtweise seines Lehrers Platon auf die Gegenstände der Mathematik. Dieser war der Ansicht, dass die eigentlichen Gegenstände der mathematischen Wissenschaften Geometrie und Arithmetik sowohl unveränderlich als nicht wahrnehmbar sind, und daher als getrennt von den physikalischen Gegenständen existierend angenommen werden müssen. Die Gründe, die Platon dafür hatte, sind von zweierlei Art.
