When talking about decisionmaking for children with a life-threatening condition, the death of children with brain tumors deserves special attention. The last days of the lives of these children can be particularly harsh for bystanders, and raise questions about the suffering of these children themselves. In the Netherlands, these children are part of the group for whom a wide range of end-of-life decisions are discussed, and questions raised. What does the end-of-life for these children look like, and what motivates physicians (...) and parents to make decisions that may affect the life and death of these children? This article highlights the story of the parents of the sisters Roos and Noor. When both their daughters were diagnosed with a hereditary brain tumor, they had to make similar decisions twice. Their story sheds light on the suffering of children in the terminal phase, and how this suffering may motivate parents and physicians to make decisions that influence the end of life of these children’s lives.We argue that complete knowledge about suffering in the terminal phase of children with brain tumors is impossible. However, by collecting experiences like those of Roos and Noor, we can move toward an experienced-based understanding and better guide parents and physicians through these hardest of decisions.

One of the hardest questions to answer for a (Neo)platonist is to what extent and how the changing and unreliable world of sense perception can itself be an object of scientific knowledge. My dissertation is a study of the answer given to that question by the Neoplatonist Proclus (Athens, 411-485) in his Commentary on Plato’s Timaeus. I present a new explanation of Proclus’ concept of nature and show that philosophy of nature consists of several related subdisciplines matching the ontological stratification (...) of nature. Moreover, I demonstrate that for Proclus philosophy of nature is a science, albeit a hypothetical one, which takes geometry as its methodological paradigm. I also offer an explanation of Proclus’ view of what is later called the mathematization of physics, i.e. the role of the substance of mathematics, as opposed to its method, in explaining the natural world. Finally, I discuss Proclus’ views of the discourse of philosophy of nature and its iconic character. (shrink)

This is the first volume of a projected three-volume work on the little known South Indian folk cult of the goddess Draupadi and on the classical epic, the Mahabharata, that the cult brings to life in mythic, ritual and dramatic forms.

This article offers a critical reading of three major biographies of the British novelist and philosopher Iris Murdoch. It considers in particular how a limited concern for gender issues has hampered their portrayals of Murdoch as a creator of images and ideas. The biographies are then contrasted to a biographical sketch constructed from Murdoch's philosophical writing. The assessment of the biographies is set against the larger background of the relation between women and philosophy. In doing so, the paper offers a (...) critical response to Sally Haslanger's recent “Musings” (Haslanger 2008), which is contrasted to Virginia Woolf's A Room of One's Own (1929) and Michèle Le Doeuff's Hipparchia's Choice (2007).

This study examines the answers of Suarez and Descartes to basic questions regarding the philosophical knowledge of God. It is placed against the background of the reactions to both by Dutch Reformed theologians and philosophers in the seventeenth Century.

The goal of the present study was to investigate whether children’s cognitive strengths can compensate the accompanied weaknesses related to their specific learning difficulties. A Bayesian multigroup mediation SEM analysis in 281 fourth-grade children identified a cognitive compensatory mechanism in children with mathematical learning difficulties (n= 36): Children with weak number sense, but strong rapid naming performed slightly better on mathematics compared to peers with weak rapid naming. In contrast, a compensatory mechanism was not identified for children with a comorbid (...) mathematical and reading difficulty (n= 16). One explanation for the latter finding could relate to the lack of ability to compensate, because of the difficulties these children experience in both academic domains. These findings lead to a new direction in research on learning difficulties in mathematics and/or reading by suggesting that children with a learning disability each have a unique profile of interrelated cognitive strengths and weaknesses. Children might compensate with these strengths for their weaknesses, which could lead to (small) learning gains in the affected domain. (shrink)

Involving patients in decisions on primary prevention can be questioned from an ethical perspective, due to a tension between health promotion activities and patient autonomy. A nurse-led intervention for prevention of cardiovascular diseases, including counselling (risk communication, and elements of shared decision-making and motivational interviewing) and supportive tools such as a decision aid, was implemented in primary care. The aim of this study was to evaluate the nurse-led intervention from an ethical perspective by exploring in detail the experiences of patients (...) with the intervention, and their views on the role of both the nurse and patient. The study had a qualitative design. 18 patients who had received the intervention participated. Data were gathered by in-depth interviews. The interviews were analysed using directed content analysis. The findings revealed that patients perceived the consultations not as an infringement on their autonomy, but as supportive to risk reduction efforts they tried but found hard to realise. They specifically emphasised the role of the nurse, and appreciated the nurse's realistic advice, encouragement, and help in understanding. Patients' views on and experiences with risk management are in line with notions of relational autonomy, caring cooperation and communicative action found in the literature. We conclude that patients define the relationship with the nurse as shared work in the process of developing a healthier lifestyle. (shrink)

In late antiquity, logic developed into what Ebbesen calls the LAS, the Late Ancient Standard. This paper discusses the Neoplatonic use of LAS, as informed by epistemological and metaphysical concerns. It demonstrates this through an analysis of the late ancient debate about hypothetical and categorical logic as manifest in the practice of syllogizing Platonic dialogues. After an introduction of the Middle Platonist view on Platonic syllogistic as present in Alcinous, this paper presents an overview of its application in the syllogizing (...) practice of Proclus and others. That overview shows that the two types were considered two sides of the same coin, to be used for the appropriate occasions, and both relying on the methods of dialectic as revealing the structure of knowledge and reality. Pragmatics, dialectic, and didactic choices determine which type or combination is selected in syllogizing Plato. So even though there is no specific Neoplatonic logic, there is a specific Neoplatonic use of LAS. (shrink)

"Initium ut esset, creatus est homo": Iris Murdoch on Authority and Creativity In 1970 the British novelist and philosopher Iris Murdoch published both her thirteenth novel, A Fairly Honourable Defeat, and her best known work of philosophy, The Sovereignty of Good. Given the proximity of these publication dates, it does not surprise that there are many points of comparison between these two works. The novel features, for instance, a character writing a work of moral philosophy not unlike Murdoch's own The (...) Sovereignty of Good, while another character exemplifies her moral philosophy in his life.This article proposes a reading of the novel as a critical commentary on the philosophical work, focusing on the tension between creation and authority. While Murdoch considers humans to be first and foremost creative, she is at the same time wary of the misleading nature of any act of creation. For Murdoch, any creator and any creation—a beautiful picture as well as a watertight theory—may transmit a certain authority, and that authority may get in the way of acknowledging reality. It thus hinders the moral life, which for Murdoch should be thought of as a life of attention—to reality and ultimately to the Good—rather than a series of wilful creations and actions.A Fairly Honourable Defeat queries the possibility and danger of creation, through different characters as well as through images of cleanliness and messiness. Thus, the character whose book of moral philosophy is challenged and who is found wanting when putting his ideas to practice, likes ‘to get things clear’. Another character, whose interferences create the novel's drama, has a self-confessed ‘passion for cleanliness and order’. The saint of the story, in contrast, does not interfere unless by necessity, and resides in one of the filthiest kitchens in the history of literature. Yet, none of the main characters exemplifies a solution to the tension between creation and authority found in Murdoch's philosophy. An indication of a solution is found in a minor character, and in his creations of outrageous bunches of flowers, unusual meals, and absurd interiors. Yet, its location in a subplot suggests that this solution is not in any way final. It is concluded that any final solution should not be expected, not in the least because of the pervasive nature of the tension between creation and authority, which goes well beyond Murdoch's own authorship.

The recent discovery of an indeterministic system in classical mechanics, the Norton dome, has shown that answering the question whether classical mechanics is deterministic can be a complicated matter. In this paper I show that indeterministic systems similar to the Norton dome were already known in the nineteenth century: I discuss four nineteenth century authors who wrote about such systems, namely Poisson, Duhamel, Boussinesq and Bertrand. However, I argue that their discussion of such systems was very different from the contemporary (...) discussion about the Norton dome, because physicists in the nineteenth century conceived of determinism in essentially different ways: whereas in the contemporary literature on determinism in classical physics, determinism is usually taken to be a property of the equations of physics, in the nineteenth century determinism was primarily taken to be a presupposition of theories in physics, and as such it was not necessarily affected by the possible existence of systems such as the Norton dome.

This chapter provides an analysis of the often mentioned but rarely explained ‘systematicity’ of Proclus’ version of Neoplatonism, and an introduction into the basics of his metaphysics. Starting from the assumption that any philosophical system stems from the desire for explanations, and that for Platonists this involved bridging the opposition between explanandum and explanans, it formulates a number of ensuing requirements, which lead to the construction of what is generally called a philosophical system. The authors then show how this pans (...) out in Proclus’ metaphysics, specifically the One, causality, and triads. Finally, they address the relevance of all this for human life, and briefly evaluate the downsides of Proclus’ systematicity and what sets him apart from predecessors. (shrink)

In this paper I show that Proclus is an adherent of the Classical Model of Science as set out elsewhere in this issue (de Jong and Betti 2008), and that he adjusts certain conditions of the Model to his Neoplatonic epistemology and metaphysics. In order to show this, I develop a case study concerning philosophy of nature, which, despite its unstable subject matter, Proclus considers to be a science. To give this science a firm foundation Proclus distills from Plato’s Timaeus (...) the basic concepts Being and Becoming and a number of basic propositions, among others the quasi-definitions of the basic concepts. He subsequently explains the use of these quasi-definitions, that are actually epistemic guides, in such a way that he obtains a connection between a rational and an empirical approach to the natural world. A crucial task in establishing the connection is performed by the faculty of doxa and by geometrical conversion. The result is that Proclus secures a universal, necessary and known foundation for all of philosophy of nature. (shrink)

During the period 1860-1880, a number of physicists and mathematicians, including Maxwell, Stewart, Cournot and Boussinesq, used theories formulated in terms of physics to argue that the mind, the soul or a vital principle could have an impact on the body. This paper shows that what was primarily at stake for these authors was a concern about the irreducibility of life and the mind to physics, and that their theories can be regarded primarily as reactions to the law of conservation (...) of energy, which was used among others by Helmholtz and Du Bois-Reymond as an argument against the possibility of vital and mental causes in physiology. In light of this development, Maxwell, Stewart, Cournot and Boussinesq showed that it was still possible to argue for the irreducibility of life and the mind to physics, through an appeal to instability or indeterminism in physics: if the body is an unstable or physically indeterministic system, an immaterial principle can act through triggering or directing motions in the body, without violating the laws of physics.

This study was designed to investigate the trust relationship between parents and teachers in first grade. Additional research questions were whether trust was related to ethnicity and reading performance. The five facets of trust; benevolence, reliability, competence, honesty and openness, were measured on a 4-point Likert scale. Reading performance was measured by the three-minute test. Parents were found to have more trust in the reliability, competence and honesty of teachers than teachers in parents. Native-Dutch and immigrant parents have the same (...) trust level towards their children?s teacher. However, teachers reported lower trust levels on all five facets of trust for immigrant parents. Our findings indicated that ethnicity has no influence on parents trust in teachers, but ethnicity may explain teachers? trust in parents. Some support was found for the assumption that teachers? trust plays a role in reading performance. Children were found to have higher reading performance when teachers reported higher trust in the benevolence and openness of parents. (shrink)

The theory of quantum mechanics has often been thought to show an affinity with logical empiricism: in both, observation plays a central role, and questions about what is unobservable are dismissed. However, there were also strong tensions between the logical empiricism of the Vienna Circle and implications drawn from quantum physics. In the 1920s and 1930s, many physicists thought that quantum mechanics revealed a limit to what could be known scientifically, and this opened the door to a wide range of (...) speculations, in which quantum mechanics was connected with free will, organic life, psychology, and religion—speculations in which many leading quantum physicists were engaged. Members of the Vienna Circle, such as Frank and Schlick, looked at quantum mechanics for a confirmation of their empiricist views, but they were at the same time critical about these wider implications drawn from quantum mechanics, which in their eyes were connected with broader mystical and irrational trends in society. They engaged in particular with the views of Bohr and Jordan, both of whom expressed a sympathy for logical empiricism while at the same time arguing for claims that proved hard to reconcile with the scientific world conception of the Vienna Circle.

Recent publications have argued that practical wisdom is increasingly important for medical practices, particularly in complex contexts, to stay focused on giving good care in a moral sense to each individual patient. Our empirical investigation into an ordinary medical practice was aimed at exploring whether the practice would reveal practical wisdom, or, instead, adherence to conventional frames such as guidelines, routines and the dominant professional discourse. We performed a thematic analysis both of the medical files of a complex patient and (...) her daughter’s diary. We did find practical wisdom, but only sporadically, whereas it has proved to be essential for professional care. This deficit appeared to result from several factors like: the organization of the practice; established routines; a hierarchical culture; and a traditional medical discourse. Moreover, we discerned various negative consequences. More empirical research into practical wisdom in everyday medical practices is needed for the benefit of professional and morally good care for every patient. (shrink)

This article starts from the observation that Socratic dialogues in the Nelson–Heckmann tradition can create a sense of belonging or community among participants. This observation has led me to the current argument that Socratic dialogue offers an alternative to more prominent forms of conversation, which I have called ‘discussion’ and ‘discourse of uncritical acceptance.’ I explain the difference between these forms of conversation by considering the role of experience in Socratic dialogue and the requirement that participants put themselves in each (...) other’s shoes. My argument is structured according to the different phases in a Socratic dialogue and placed within the literature on this method, as well as Hannah Arendt’s writing on imagination. (shrink)

The development of rigorous foundations of differential calculus in the course of the nineteenth century led to concerns among physicists about its applicability in physics. Through this development, differential calculus was made independent of empirical and intuitive notions of continuity, and based instead on strictly mathematical conditions of continuity. However, for Boltzmann and Poincaré, the applicability of mathematics in physics depended on whether there is a basis in physics, intuition or experience for the fundamental axioms of mathematics—and this meant that (...) to determine the status of differential equations in physics, they had to consider whether there was a justification for these mathematical continuity conditions in physics. For this reason, their ideas about continuity and discreteness in nature were entangled with epistemology and philosophy of mathematics. They reached opposite conclusions: Poincaré argued that physicists must work with a continuous representation of nature, and thus with differential equations, while Boltzmann argued that physicists must ultimately take nature to be discrete.

Philosophy is one of the least inclusive disciplines in the humanities and this situation is changing only very slowly. In this article I consider how one of the women of the Wartime Quartet, Iris Murdoch, can help to challenge this situation. Taking my cue from feminist and philosophical practices, I focus on Murdoch's experience of being a woman and a philosopher and on the role experience plays in her philosophical writing. I argue that her thinking is best characterised with the (...) notion of common sense orsensus communis. This term recognises her understanding of philosophy as based in experience and as a shared effort ‘to make sense of our life’, as Mary Midgley puts it. (shrink)

Proclus was one of the last great philosophers of Antiquity. His legacy in the cultural history of the west can hardly be overestimated. This book is the most comprehensive guide to Proclus' life, thought and legacy that is currently available.

The reversibility problem (better known as the reversibility objection) is usually taken to be an internal problem in the kinetic theory of gases, namely the problem of how to account for the second law of thermodynamics within this theory. Historically, it is seen as an objection that was raised against Boltzmann's kinetic theory of gases, which led Boltzmann to a statistical approach to the kinetic theory, culminating in the development of statistical mechanics. In this paper, I show that in the (...) late nineteenth century, the reversibility problem had a much broader significance - it was widely discussed and certainly not only as an objection to Boltzmann's kinetic theory of gases. In this period, there was a conflict between mechanism and irreversibility in physics which was tied up with central issues in philosophy of science such as materialism, empiricism and the need for mechanistic foundations of physical theories, as well as with concerns about the heat death of the universe. I discuss how this conflict was handled by the major physicists of the period, such as Maxwell, Kelvin, Duhem, Poincaré, Mach and Planck, as well as by a number of lesser-known authors. (shrink)

Making adaptive choices between solution strategies is a central element of contemporary mathematics education. However, previous studies signal that students make suboptimal choices between mental and written strategies to solve division problems. In particular, some students of a lower math ability level appear inclined to use mental strategies that lead to lower performance. The current study uses a pretest-training-posttest design to investigate the extent to which these students’ choices for written strategies and performance may be increased. Sixth graders of below-average (...) mathematics level (N = 147) participated in one of two training conditions: an explicit-scaffolding training designed to promote writing down calculations or a practice-only training where strategy use was not explicitly targeted. Written strategy choices and performance increased considerably from pretest to posttest for students in both training conditions, but not in different amounts. Exploratory results suggest that students’ strategy choices may also be affected by their attitudes and beliefs and the sociocultural context regarding strategy use. (shrink)

In this paper I examine the foundations of Laplace's famous statement of determinism in 1814, and argue that rather than derived from his mechanics, this statement is based on general philosophical principles, namely the principle of sufficient reason and the law of continuity. It is usually supposed that Laplace's statement is based on the fact that each system in classical mechanics has an equation of motion which has a unique solution. But Laplace never proved this result, and in fact he (...) could not have proven it, since it depends on a theorem about uniqueness of solutions to differential equations that was only developed later on. I show that the idea that is at the basis of Laplace's determinism was in fact widespread in enlightenment France, and is ultimately based on a re-interpretation of Leibnizian metaphysics, specifically the principle of sufficient reason and the law of continuity. Since the law of continuity also lies at the basis of the application of differential calculus in physics, one can say that Laplace's determinism and the idea that systems in physics can be described by differential equations with unique solutions have a common foundation.

This paper aims to show that the development of Feyerabend’s philosophical ideas in the 1950s and 1960s largely took place in the context of debates on quantum mechanics. In particular, he developed his influential arguments for pluralism in science in discussions with the quantum physicist David Bohm, who had developed an alternative approach to quantum physics which (in Feyerabend’s perception) was met with a dogmatic dismissal by some of the leading quantum physicists. I argue that Feyerabend’s arguments for theoretical pluralism (...) and for challenging established theories were connected to his objections to the dogmatism and conservatism he observed in quantum physics. However, as Feyerabend gained insight into the physical details and historical complexities which led to the development of quantum mechanics, he gradually became more modest in his criticisms. His writings on quantum mechanics especially engaged with Niels Bohr; initially, he was critical of Bohr’s work in quantum mechanics, but in the late 1960s, he completely withdrew his criticism and even praised Bohr as a model scientist. He became convinced that however puzzling quantum mechanics seemed, it was methodologically unobjectionable – and this was crucial for his move towards ‘anarchism’ in philosophy of science. (shrink)

Besides offering opportunities in both clinical and non-clinical domains, the application of novel neuroimaging technologies raises pressing dilemmas. ‘Responsible Research and Innovation’ (RRI) aims to stimulate research and innovation activities that take ethical and social considerations into account from the outset. We previously identified that Dutch neuroscientists interpret “responsible innovation” as educating the public on neuroimaging technologies via the popular press. Their aim is to mitigate (neuro)hype, an aim shared with the wider emerging RRI community. Here, we present results of (...) a media-analysis undertaken to establish whether the body of articles in the Dutch popular press presents balanced conversations on neuroimaging research to the public. We found that reporting was mostly positive and framed in terms of (healthcare) progress. There was rarely a balance between technology opportunities and limitations, and even fewer articles addressed societal or ethical aspects of neuroimaging research. Furthermore, neuroimaging metaphors seem to favour oversimplification. Current reporting is therefore more likely to enable hype than to mitigate it. How can neuroscientists, given their self-ascribed social responsibility, address this conundrum? We make a case for a collective and shared responsibility among neuroscientists, journalists and other stakeholders, including funders, committed to responsible reporting on neuroimaging research.

In the mid-eighteenth century, it was usually taken for granted that all curves described by a single mathematical function were continuous, which meant that they had a shape without bends and a well-defined derivative. In this paper I discuss arguments for this claim made by two authors, Emilie du Châtelet and Roger Boscovich. I show that according to them, the claim follows from the law of continuity, which also applies to natural processes, so that natural processes and mathematical functions have (...) a shared characteristic of being continuous. However, there were certain problems with their argument, and they had to deal with a counterexample, namely a mathematical function that seemed to describe a discontinuous curve. (shrink)
