There is a longstanding debate on the metaphysical relation between quantum states and the systems they describe.

In this paper I investigate the question of what that claim might be taken to mean in light of these theorems. It is argued that, even if one accepts the framework and assumptions (...) employed by such theorems, such a conclusion is not warranted.

El ensayo procura explicar la noción de experiencia en el arte desde la filosofia hermenéutica. Para ello desarrolla los siguienres pasos: 1. Su temporalidad como una experiencia de la actualidad en el encuentro de los interlocutores, la obra de arte y el receptor. 2. La importancia de la conversación como modelo para el encuentro. 3. El reconocimiento y la apertura de un horizonte de sentido. Esta experiencia es un acomecimiento que lo cambia a uno mismo e implica por lo tanto (...) una atención especial a la representación, ejecución o realización de la obra de arte. (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.

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.

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.

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)

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)

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)

Can a contemplative philosopher describe a particular religious practice as superstitious, or is he thereby overstepping his boundaries? I will discuss the way in which the Wittgensteinian philosopher of religion D. Z. Phillips uses ‘Superstition’ as a contemplative term. His use of the distinction between genuine religion and superstition is not a weakness as is often supposed, but a necessity. Without contemplating ‘Superstition’ and ‘genuine religion’ Phillips would not have been able to elucidate the meaning that religious beliefs have in (...) the lives of both the faithful and their critics. I will defend the aptness of Phillips’s use of this term and illustrate his approach using examples such as the concept of genuine friendship or gratitude, and then I apply this approach to the question whether, from a philosophical point of view, particular Christian practices such as the prosperity gospel are genuinely religious or should be called superstitious.

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)

In this article, a novel Wittgensteinian approach to philosophy of religion is presented which uses autobiographical exposition as a way of clarifying religious concepts. After analyzing what Wittgenstein is trying to accomplish in his philosophical approach, Wittgenstein’s type of grammatical inquiry into concept formation is applied to religion in this very straightforward manner. How a child learns to use religious concepts and how people check whether the child is using these concepts correctly, reminds us of the actual role these concepts (...) play in our discourses. In the third and fourth sections, the Wittgensteinian investigation of concept formation into religion conducted in this article is used to establish that the two common criticisms, namely that a Wittgensteinian approach fails to acknowledge that for believers God is real and that religious conflicts exist, are misplaced. It is shown that a Wittgensteinian approach in philosophy of religion merits renewed attention. (shrink)

With this article, I wish to introduce the concept of ‘faith envy’. From time to time, both believers and non-believers envy those who have faith or more faith. People envy, for example, Muslims or Charismatics for the significance and certainty of their convictions in their lives. I propose using ‘faith envy’ as an angle to investigate faith and religious language. This perspective opens up important new questions about faith. If we look at faith from this angle, we see aspects of (...) faith that remain obscure in many debates on religion, aspects beyond historical or factual matters. Firstly, I explore what it is exactly that is envied in faith envy. Secondly, I argue for the use of the concept ‘envy’ rather than ‘jealousy’ or ‘admiration’ in this context. Thirdly, I indicate how using the concept of faith envy may open up new theoretical perspectives on faith and in particular the nature of religious language. I show how the lives and works of Sören Kierkegaard, Ludwig Wittgenstein and Simone Weil are illuminated by looking at them as people who envy faith. I conclude this article by providing some impressions of what novel perspectives using the concept of faith envy may bring to light. (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)

"Williams's masterful translation satisfies (at last!) a long-standing need. There are lots of good translations of Augustine's great work, but until now we have been forced to choose between those that strive to replicate in English something of the majesty and beauty of Augustine's Latin style and those that opt instead to convey the careful precision of his philosophical terminology and argumentation. Finally, Williams has succeeded in capturing both sides of Augustine's mind in a richly evocative, impeccably reliable, elegantly readable (...) presentation of one of the most impressive achievements in Western thought--Augustine's Confessions." --Scott MacDonald, Professor of Philosophy and Norma K.

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)

The Moral Nexus develops and defends a new interpretation of morality—namely, as a set of requirements that connect agents normatively to other persons in a nexus of moral relations. According to this relational interpretation, moral demands are directed to other individuals, who have claims that the agent comply with these demands. Interpersonal morality, so conceived, is the domain of what we owe to each other, insofar as we are each persons with equal moral standing. The book offers an interpretative argument (...) for the relational approach. Specifically, it highlights neglected advantages of this way of understanding the moral domain; explores important theoretical and practical presuppositions of relational moral duties; and considers the normative implications of understanding morality in relational terms. The book features a novel defense of the relational approach to morality, which emphasizes the special significance that moral requirements have, both for agents who are deliberating about what to do and for those who stand to be affected by their actions. The book argues that relational moral requirements can be understood to link us to all individuals whose interests render them vulnerable to our agency, regardless of whether they stand in any prior relationship to us. It also offers fresh accounts of some of the moral phenomena that have seemed to resist treatment in relational terms, showing that the relational interpretation is a viable framework for understanding our specific moral obligations to other people.

At the 1927 Como conference Bohr spoke the famous words “It is wrong to think that the task of physics is to find out how nature is. Physics concerns what we can say about nature.” However, if the Copenhagen interpretation really adheres to this motto, why then is there this nagging feeling of conflict when comparing it with realist interpretations? Surely what one can say about nature should in a certain sense be interpretation independent. In this paper I take Bohr’s (...) motto seriously and develop a quantum logic that avoids assuming any form of realism as much as possible. To illustrate the non-triviality of this motto, a similar result is first derived for classical mechanics. It turns out that the logic for classical mechanics is a special case of the quantum logic thus derived. Some hints are provided as to how these logics are to be used in practical situations and finally, I discuss how some realist interpretations relate to these logics. (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)

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)

We should approach this topic with great fear and respect. It is not a merely “academic” issue. Human rights are trampled upon in the East as in the West, in the North as in the South of our planet.

Chemical structures are among the trademarks of our profession, as surely chemical as flasks, beakers and distillation columns. When someone sees one of us busily scribbling formulas or structures, he or she has no trouble identifying a chemist. Yet these familiar objects, which accompany our work from start to end, from the initial doodlings (Fig. I) to the final polished artwork in a publication (Fig. II), are deceptively simple. They raise interesting and difficult questions about representation. It is the intent (...) of this article to reflect upon molecular graphics. (shrink)
