The interpretation of quantum mechanics has been a problem since its founding days. A large contribution to the discussion of possible interpretations of quantum mechanics is given by the so-called impossibility proofs for hidden variable models; models that allow a realist interpretation. In this thesis some of these proofs are discussed, like von Neumann’s Theorem, the Kochen-Specker Theorem and the Bell-inequalities. Some more recent developments are also investigated, like Meyer’s nullification of the Kochen-Specker Theorem, the MKC-models and Conway and Kochen’s (...) Free Will Theorem. This last one is taken to suggest that the problems that arise for certain interpretations of quantum mechanics are not limited to realist interpretations only, but also affect certain instrumentalist interpretations. It is argued that one may arrive at a more satisfying interpretation of quantum mechanics if one adopts a logic that seems more compatible with the instrumentalist viewpoint namely, intuitionistic logic. The motivations for adopting this form of logic rather than classical logic or quantum logic are linked to some of the philosophical ideas of Bohr. In particular a new interpretation of Bohr’s notion of complementarity is proposed. Finally some possibilities are explored for linking the intuitionistic interpretation of quantum mechanics to the mathematical formalism of the theory. (shrink)

This article argues for acknowledging the existence of an absolute distinction between faith and science. It is often assumed in the science and religion debate that such a distinction would be ahistorical and uncontextual. After discussing this critique, the analogy with love and facts will be used to explain how an absolute distinction between faith and science may exist nonetheless. This contrast, however, does not imply compartmentalization. It is shown that the absolute distinction between faith and science is of crucial (...) importance to understand the historical contexts that so many contributors to the science and religion debate refer to in their argument against the approaches of Independence or Contrast. The article concludes that within our messy and complex practices there is an absolute distinction between faith and science—our historical contexts cannot be understood without it. (shrink)

Faith Envy explores the idea that both believers and nonbelievers envy those with more faith. Hermen Kroesbergen shows how philosophers Kierkegaard, Wittgenstein, and Weil, who each had their own kind of faith envy, can serve as guides to this phenomenon and the contemporary concept of faith.

This book discusses the Aristotelian setting of Thomas Hobbes' main work on natural philosophy, "De Corpore (1655).

A well known logical loophole for Bell’s theorem is that it relies on setting independence: the assumption that the state of a system is independent of the settings of a measurement apparatus probing the system. In this paper the implications of rejecting this assumption are studied from an operationalist perspective. To this end a generalization of the ontic models framework is proposed that allows setting dependence. It is shown that within this framework Bell’s theorem reduces to the conclusion that no-signaling (...) requires randomness at the epistemic level even if the underlying ontology is taken to be deterministic. The ideas underlying the framework are further used to defend setting dependence against the charges of being incompatible with free will and scientific methodology. The paper ends however with the sketch of a new problem for setting dependence: a necessary gap between the ontic and the epistemic level that may prevent the formulation of a successful setting dependent theory.

We argue that an understanding of livestock farming as normative practice clarifies how sustainability is to be understood in livestock farming. The sustainability of livestock farming is first approached by investigating its identity. We argue that the economic aspect qualifies and the formative aspect founds the livestock farming practice. Observing the normativity related to these aspects will be the first task for the livestock farmer. In addition, we can distinguish conditioning norms applicable to the livestock farming practice which should be (...) observed for competent performance of the practice. Failing to do justice to this normativity might affect the practice’s sustainability only in the long term—this is especially the case with conditioning norms. Motives to observe normativity have, therefore, the character of an ultimate conviction regarding the flourishing of the practice. Finally, the sustainability of the livestock farming practice crucially depends on the broader food system of which it is part. (shrink)

This article investigates how we should understand the prayer ‘But thy will not mine be done’, using Wittgenstein’s ordinary language approach. The later Wittgenstein argued that philosophy’s task is to assemble reminders of how language is used in daily life for a particular purpose. This approach offers a way to understand how, despite what theologians have argued, ‘Thy will be done’ is neither making prayer useless, nor is it fundamental to all petitionary prayers. Firstly, the framework and method of Wittgenstein’s (...) ordinary language will be explained. Secondly, reminders will be assembled for the purpose of showing that the prayer ‘Thy will be done’ does not need to make praying useless. Thirdly, the appropriate reminders to refute the statement that ‘Thy will be done’ is fundamental to all petitionary prayers will be presented. And, finally, these two sets of reminders will be connected to one another to provide a more truthful understanding of the prayer ‘Thy will be done’. (shrink)

In recent years, evolutionary theorists have come to recognize that the reductionist, individualist, gene-centered approach to evolution cannot sufficiently account for the emergence of complex biological systems over time. Peter A. Corning has been at the forefront of a new generation of complexity theorists who have been working to reshape the foundations of evolutionary theory. Well known for his Synergism Hypothesis—a theory of complexity in evolution that assigns a key causal role to various forms of functional synergy—Corning puts this theory (...) into a much broader framework in _Holistic Darwinism_, addressing many of the issues and concepts associated with the evolution of complex systems. Corning's paradigm embraces and integrates many related theoretical developments of recent years, from multilevel selection theory to niche construction theory, gene-culture coevolution theory, and theories of self-organization. Offering new approaches to thermodynamics, information theory, and economic analysis, Corning suggests how all of these domains can be brought firmly within what he characterizes as a post–neo-Darwinian evolutionary synthesis.

Het verhaal van de natuurkunde is ook een persoonlijk verhaal, want achter de feiten gaan altijd mensen schuil. Van Einstein, die Beethoven op zijn viool probeert te spelen, tot Van Swinden, die jarenlang in het planetarium in Franeker werkt. Cees Andriesse, die 'Titan kan niet slapen' schreef, een biografie over Christiaan Huygens, heeft veel gevoel voor deze verhalen. In deze nieuwe geschiedenis van de natuurkunde wordt dan ook ruim aandacht besteed aan de zoektocht en wederwaardigheden van grote figuren, maar ook (...) van collega's uit de tijd dat Andriesse in Groningen werkte. De wetenschap draait om onmiskenbare relaties tussen harde feiten; die gaan spreken onder de pen van Andriesse, die oog heeft voor de ontdekkers en zichtbaar maakt hoe zijn eigen begrip is ontstaan. Het is hem niet te doen om de mechanisering van de natuurkunde, maar om de historisering daarvan. Dit boek biedt een nieuw perspectief op grote ontdekkingen, waarbij zowel God, als literatuur als psychologie een rol spelen. (shrink)

Johannine ethics was a problematic topic for a long time and has only been an acceptable and fruitful area of research since 2012. To stimulate and guide future research, this article proposes a model of Johannine ethics that consists of five aspects: Graeco-Roman virtue ethics is the broad ethical context for Johannine ethics; family is the theological context for Johannine ethics; mimesis is central to Johannine ethics; moral reasoning is the cognitive route to ethics; Spirit and community empower ethical living. (...) The argument is that the Johannine writings present ethics as divine family education that has mimesis at its centre and is facilitated by moral reasoning and the Spirit as the moral force. An Appendix contains a list of publications on Johannine ethics between 2012 and 2022. (shrink)

In many ways, the African world view and African theology are closer to nature than Euro-American theology is. This can be seen, for example, in its emphasis on holism and interconnectedness, and its inclination to consider all natural objects to be inhabited by the spirit world. This article argues that this closeness to nature should not be confused with a Romantic reverence for nature. Since the 19th century, Romanticism has been very influential in the Euro-American idea of nature. Nature came (...) to be seen as something that is both good and valuable in itself. The conception of nature that is dominant in African ways of thinking is very different: nature is seen as potentially threatening and, at best, ambivalent; and respect for nature and living in balance with nature is judged by the extent to which they help humans to live successfully. In this article, a theological and philosophical clarification of these two contrasting conceptions of nature is combined with qualitative anthropological analysis of the way Zambian pastors speak about nature in their sermons. These two approaches together bring out the often-misinterpreted non-Romantic idea of nature in African theology. Contribution: This article clarifies the important idea of nature within the context of African theology. It brings out how the meaning of holism and sacredness in African settings differs from the meaning of these ideas in Western eco-theological contexts. Hereby, it untangles important confusions in the field of eco-theology. (shrink)

This book presents a theoretical treatment of externalities, public goods, and club goods. The new edition updates and expands the discussion of externalities and their implications, coverage of asymmetric information, underlying game-theoretic formulations, and intuitive and graphical presentations. Aimed at well-prepared undergraduates and graduate students making a serious foray into this branch of economics, the analysis should also interest professional economists wishing to survey recent advances in the field. No other single source for the range of materials explored is currently (...) available. Topics investigated include Nash equilibrium, Lindahl equilibria, club theory, preference-revelation mechanism, Pigouvian taxes, the commons, Coase Theorem, and static and repeated games. The authors use mathematical techniques only as much as necessary to pursue the economic argument. They develop key principles of public economics that are useful for subfields such as public choice, labor economics, economic growth, international economics, environmental and natural resource economics, and industrial organization.

We do not need ‘the earth’ as the space for encounter and cooperation between world religions in the way Moltmann suggests. Firstly, this fails to do justice to the contemporary situation concerning religious diversity: people from different religions have no problem in working together either for promoting ecological goals or for fighting them together. Within religions, there are often greater divergences between eco-friendly and anti-ecological adherents of that same religion. Secondly, Moltmann’s proposal misguidedly confuses boundaries of beliefs and boundaries of (...) grammar concerning religious diversity. Paying attention to religions as grammar provides a more accurate picture of the reality concerning world religions from an ecological perspective. In the final section of this article, I present some suggestions on moving forward in the debate about ecology from within this new perspective. We need to keep in mind that it is not religions but people who have opinions about ecology. The dialogue that needs to take place is not a high-level bureaucratic one between officials of different religions but one between people. In this grassroots-level discussion, it is important to listen to the other person rather than to consider him or her as a representative of his or her religion. We should not allow people to claim an entire religion for their position, dismissing others as revisionists. Religions are grammars that can express both eco-friendly and anti-ecological messages.Contribution: This article contributes to an in-depth understanding of religious diversity; it proves the usefulness of the distinction between grammar and beliefs in the study of religion and demonstrates this using the case of ecotheology as an example.

One way to reconstruct the miracle argument for scientific realism is to regard it as a statistical inference: since it is exceedingly unlikely that a false theory makes successful predictions, while it is rather likely that an approximately true theory is predictively successful, it is reasonable to infer that a predictively successful theory is at least approximately true. This reconstruction has led to the objection that the argument embodies a base rate fallacy: by focusing on successful theories one ignores the (...) vast number of false theories some of which will be successful by mere chance.In this paper, I shall argue that the cogency of this objection depends on the explanandum of the miracle argument. It is cogent if what is to be explained is the success of a particular theory. If, however, the explanandum of the argument is the distribution of successful predictions among competing theories, the situation is different. Since the distribution of accidentally successful predictions is independent of the base rate, it is possible to assess the base rate by comparing this distribution to the empirically found distribution of successful predictions among competing theories.

Francis Bacon (1561-1626) was een belangrijk Engels staatsman en invloedrijk humanistisch filosoof. Zijn publicaties liggen aan de oorsprong van onze moderne visie op het wetenschappelijk onderzoek. Toch is hij vandaag weinig bekend: in overzichtswerken komt hij nauwelijks aan bod en er verschijnt relatief weinig over hem. Dit boek brengt Bacons ideeën opnieuw voor het volle voetlicht. Bacon schreef toegankelijke teksten: essays, manifesten voor een nieuwe wetenschap en zelfs een fictief verhaal over een ideale kennismaatschappij. Zijn stijl was helder en vaak (...) aforistisch, met bondige en sprankelende zinnen die we vandaag zonder dralen zouden retweeten. Dit eigenzinnige boek bespreekt de belangrijkste juridische, filosofische en wetenschapsethische inzichten van Bacon, verweven met diens intrigerende levenswandel. Zijn uitspraken zijn door de auteur gemoderniseerd en voorgesteld als tweets. Bacons beschouwingen zouden ook vandaag wel eens het verschil kunnen maken in de wetenschappelijke wereld die stilaan in het slop raakt door de vermarkting van de universiteit. (shrink)

The use of probability theory is widespread in our daily life as well as in scientific theories. In virtually all cases, calculations can be carried out within the framework of classical probability theory. A special exception is given by quantum mechanics, which gives rise to a new probability theory: quantum probability theory. This dissertation deals with the question of how this formalism can be understood from a philosophical and physical perspective. The dissertation is divided into three parts. In the first (...) part, the formalism of quantum probability theory and its relation to quantum mechanics is presented. The second part considers the possibility of reformulating quantum probability theory to embed it within classical probability. Mathematically, this possibility overlaps with the possibility of the existence of hidden variables theories of quantum mechanics: theories that attempt to solve fundamental problems in quantum mechanics by introducing additional physical properties of systems. The conclusion of this part is that, although classical reformulations of quantum probability theory are formally possible, they offer little insight into the formalism of quantum probability theory itself. The third part regards a more direct investigation of quantum probability theory. A reformulation of quantum probability theory is obtained by constructing a quantum logic on the basis of empirical non-probabilistic predictions of quantum mechanics. In this reformulation quantum probability functions are conditional probability functions on an algebra of propositions about measurements and measurement outcomes. (shrink)

People can learn to perform new tasks very quickly by making use of lower‐level skills they have developed when learning previous tasks. Hoekstra, Martens, and Taatgen model this process, showing how a system trained on simple tasks (visual search and two working memory tasks) can then quickly learn to perform the attentional blink task, and it ends up making the same sorts of errors as people do.

Far from being non‐realism or antirealism, Wittgensteinian philosophy of religion shows the meaning of practices within which the whole weight is in the picture that God speaks. ‘The authority of the community of believers determines what is the word of God’ does not contradict ‘God himself determines what is the word of God.’ As is shown by an example of Peter Winch, the distinction between inside and outside perspectives on religious practices is already given in those practices themselves. Wittgensteinian philosophy (...) of religion does justice to the independent reality of God, without the adjustments proposed by Stephen Mulhall and Andrew Moore. (shrink)

Leadership in Africa is inextricably connected to the spirit world. Leaders may be chosen through elections or other human processes, but ultimately, they are seen as appointed by God. Leaders may base their decisions upon science or intuition, but ultimately, they let themselves be inspired by revelations from the spiritual realm. Yet, what is meant by the spirit world in this respect? In this article, a new way is explored for investigating what references to the spirit world mean. Instead of (...) discussing which theoretical concept applies to the kind of reality spirits have, or what analogy fits spirits, I demonstrate that we can discover what it means to speak of the spirit world by investigating what we already know about it before theoretical labels and comparisons. Such a Wittgensteinian approach in line with the re-emerging brand of ethnographically informed philosophy of religion enhances our understanding of what kind of reality the spirit world has. If you see leadership as being empowered by the spirit world, this is not a choice, option or interpretation, but you cannot see it any other way. Contribution: This article contributes to a better understanding of the kind of reality that the spirit world has, in particular in an African context. The topic of leadership in Africa is used here to illustrate how this kind of reality is often misunderstood. A clear understanding of the kind of reality of the spirit world is indispensable for a proper investigation of Christianity in Africa and religion in general. (shrink)

Recently Cator and Landsman made a comparison between Bell’s Theorem and Conway and Kochen’s Strong Free Will Theorem. Their overall conclusion was that the latter is stronger in that it uses fewer assumptions, but also that it has two shortcomings. Firstly, no experimental test of the Conway–Kochen Theorem has been performed thus far, and, secondly, because the Conway–Kochen Theorem is strongly connected to the Kochen–Specker Theorem it may be susceptible to the finite precision loophole of Meyer, Kent and Clifton. In (...) this paper I show that the finite precision loophole does not apply to the Conway–Kochen Theorem. (shrink)

In this article von Neumann’s proposal that in quantum mechanics projections can be seen as propositions is followed. However, the quantum logic derived by Birkhoff and von Neumann is rejected due to the failure of the law of distributivity. The options for constructing a distributive logic while adhering to von Neumann’s proposal are investigated. This is done by rejecting the converse of the proposal, namely, that propositions can always be seen as projections. The result is a weakly Heyting algebra for (...) describing the language of quantum mechanics. (shrink)

In coarse-grained environments specialists are generally predicted to dominate. Empirically, however, coexistence with generalists is often observed. We present a simple, but previously unrecognized, mechanism for coexistence of a habitat generalist and a number of habitat specialist species. In our model all species have a metapopulation structure in a landscape consisting of patches of different habitat types, governed by local extinction and colonization. Each specialist is limited to its specific type of habitat. The generalist can use more types of habitat, (...) has a lower local competitive ability but can exploit patches left open by the specialists. Our modeling shows that coexistence is easily possible. The mechanism amounts to a colonization/competition trade-off at the landscape level, where the colonization advantage of the inferior competitor does not arise from a higher colonization rate but from its ability to use more types of habitat. Habitat availability has to be intermediate: when there are few patches of each habitat, only the generalist is able to maintain itself and when there are many patches, high propagule pressure of the specialists excludes the generalist. Habitat selection or temporal variations in relative habitat quality are not necessary for coexistence. Increased niche-width, colonization rate or local competitive ability of the generalist enhances its performance compared to the specialists. Various types of habitat degradation favour generalism. When able to use a broad range of habitats, generalists can generate so much propagule pressure that only a low level of local competitive ability is needed to globally exclude the specialists. Hence, in a reversal of the original problem, the question is why there are so many specialist metapopulations? (shrink)

In 2010, the Dutch Scientific Council for Governmental Policy called for an explicit and adequate intervention ethics for policy on international development cooperation. Yet, as appears from a careful reading of their report, the council’s own overall commitment to a modernist worldview hinders the fruitful development of such an intervention ethics. There is, however, a strand in their thinking that draws attention to the importance of practical knowledge. We argue specifically that an intervention ethics for development cooperation in agriculture should (...) start from this practical knowledge, which points to the inherent normativity of agricultural development cooperation. That is, agricultural development cooperation is a normative practice of which the inherent normativity consists in facilitating other practices in the agricultural domain. As such, agricultural development cooperation should respect the normativity inherent in those other practices. (shrink)

The experience of feeling safe even in the midst of trials and temptations seems to be a central feature of the Christian faith. In this article I will try to solve some possible difficulties in understanding this kind of absolute safety by discussing some problems noted by philosophers in connection with the related statements by Socrates that a good man cannot be harmed, and by Wittgenstein that he sometimes feels absolutely safe, that nothing can injure him whatever happens. First, I (...) will investigate whether there is an invalid prediction implied in this feeling of absolute safety: how can someone know that nothing will hurt him or her? Second, I will examine whether this experience of complete safety is dependent upon impossible requirements, such as to be a good man or an impeccable Christian. Third, I will consider the character of the people who claim absolute safety as portrayed by different philosophers: do these people really need to be so cold and inhumanly detached from the world for them to be able to say that nothing can hurt them? I will argue that if, instead of asking how someone can claim absolute safety, we ask to what someone commits him- or her-self in making this claim, these difficulties disappear. (shrink)

This book employs contemporary philosophy, scientific research, and clinical reports to argue that pain, though real, is not an appropriate object of scientific generalisations or an appropriate target for medical intervention. Each pain experience is instead complex and idiosyncratic in a way which undermines scientific utility. In addition to contributing novel arguments and developing a novel position on the nature of pain, the book provides an interdisciplinary overview of dominant models of pain. The author lays the needed groundwork for improved (...) models and targeted treatments at a time when pain science, pain medicine, and philosophy are explicitly searching for both and failing to find them. The Complex Reality of Pain will be of interest to a broad range of researchers and students, including those working in philosophy of mind, philosophy of science, cognitive science, neuroscience, medicine, health, cognitive and behavioural psychology, and pain science.

Mimesis is a fundamental and pervasive human concept, but has attracted little attention from Johannine scholarship. This is unsurprising, since Johannine ethics, of which mimesis is a part, has only recently become a fruitful area of research. Bennema contends that scholars have not yet identified the centre of Johannine ethics, admittedly due to the fact that mimesis is not immediately evident in the Johannine text because the usual terminology for mimesis is missing. This volume is the first organized study on (...) the concept of mimesis in the Johannine literature. The aim of the study is to establish that mimesis is a genuine Johannine concept, to explain its particulars and to show that mimesis is integral to Johannine ethics. Bennema argues that Johannine mimesis is a cognitive, creative process that shapes the believer's identity and behaviour within the context of the divine family. Besides being instrumental in people's moral transformation, mimesis is also a vital mechanism for mediating the divine reality to people. (shrink)

Er is de laatste decennia nogal wat te doen over de metafoor en haar functie. En vaak wordt daarbij verwezen naar een belangrijke tekst van de Griekse filosoof Aristoteles. Ik wil in het hierna volgende nagaan wat Aristoteles over de metafoor zegt. Ik begin met de hierboven bedoelde passage in haar verband zo letterlijk mogelijk te vertalen. Dan bezie ik verder wat Aristoteles met de metafoor die hij als voorbeeld gebruikt, doet en vervolgens bezien we wat Aristoteles verder over de (...) ‘overdracht’ zegt, en wat enkele geleerden zeggen over Aristoteles-en-de-metafoor. Tenslotte stel ik de vraag of, afgezien van Aristoteles, er reden is om te denken dat de metafoor een ‘cognitief extra’ heeft boven een mededeling in normale bewoordingen, en speciaal de wat soms genoemd wordt ‘levende’ metafoor. Ik zelf kan daar niet van overtuigd raken. (shrink)
