In der folgenden Übersicht wird versucht, die wissenschaftstheoretischen Tätigkeiten in den Niederlanden, insbesondere auf den Gebieten der Logik und Grundlagenforschung, Philosophie der Naturwissenschaften, Philosophie der Geschichtswissenschaft und der Sozialwissenschaften zu skizzieren. In einer Schlußbetrachtung werden die allgemeinen methodologischen Fragestellungen und die daraus sich ergebenden neuen Möglichkeiten einer Wissenschaftstheorie erörtert.

Could each and every one of us, instead of interacting with actual objects, really be brains in a vat? In the first chapter of his new book, Reason, Truth and History, Professor Putnam raises this and related questions with the aim of undermining what he calls the “metaphysical realist” or “externalist” conception of reality. Putnam describes metaphysical realism as a view which holds that the world consists in “some fixed totality of mind-independent objects”; truth on this view amounts to a (...) correspondence between words or thoughts and these objects. Putnam contrasts metaphysical realism with a doctrine which he names “internalism” and calls on Kant to explicate its basic ideas. Putnam claims that Kant was the first philosopher to see clearly the difficulties inherent in metaphysical realism. The doctrine of transcendental idealism, says Putnam, represents Kant’s attempt to avoid externalism. But is Kant’s doctrine really just an early version of Putnam’s internalism? In this paper I shall argue that it is not. Although Kant obviously rejects the position Putnam calls “externalism,” I shall try to show that Kant’s metaphysical theory is distinct from internalism. Kant couples transcendental idealism with a second doctrine of empirical realism, and this enables Kant to circumvent both the internalist’s coherence theory of truth as well as a simple-minded correspondence theory. To be sure, one of Kant’s major concerns is to argue against the possibility of knowing things-in-themselves; Kant thus maintains, as Putnam correctly points out, that the nature of perceivers must figure in the nature of what is perceived. But this is not to say, as Putnam implies, that there is no mind-independent reality in Kant’s theory. On the contrary, Kant’s Refutation of Idealism—an argument that strikingly resembles the first horn of Putnam’s brain-in-a-vat dilemma—is designed to establish the existence of “matter,” which is Kant’s general term for what we might call the “external” or the “mind-independent.” Kant does argue that the perception of matter must accord with space and time, the two forms of sensibility, and this is the source of his transcendental idealism. But if we take this to mean that there cannot be anything independent of our minds or of our conceptual schemes, then we miss the point of Kant’s double doctrine of transcendental idealism and empirical realism, which is intended to avoid a coherence-only theory of truth while yet affirming that objects are knowable only as appearances. Putnam, by running together a number of Kantian notions, misrepresents Kant’s position and thus fails to see that Kant does offer an alternative to both metaphysical realism and internalism. I shall begin my defense of the claim that Kant does provide a third alternative by exploring more fully the debate between Putnam and the externalist concerning the BV dilemma. I shall then explore the Refutation of Idealism to support my claim that Putnam’s internalism is distinct from transcendental idealism. We shall see in section IV that in interpreting Kant on transcendental idealism Putnam makes two crucial mistakes which lead him to equate internalism with transcendental idealism. The result of these mistakes is discussed in section V. (shrink)

Kant’s philosophy of mathematics presents two fundamental problems of interpretation: (1) Kant claims that mathematical truths or “judgments” are synthetic a priori; and (2) Kant maintains that intuition is required for generating and/or understanding mathematical statements. Both of these problems arise for us because of developments in mathematics since Kant. In particular, the axiomatization of geometry--Kant’s paradigm of mathematical thinking--has made it seem to some commentators as, for example, Russell, that both (1) and (2) are false (Russell 1919, p. 145).2 (...) If virtually all of mathematics, including geometry, is axiomatizable, it would seem that mathematics results in analytic judgments that are totally independent of sensibility, the source, according to Kant, of intuition. In this paper I will address both of these difficulties. I shall argue that Kant’s understanding of both “synthetic” and “intuition” make his position immune to these criticisms. (shrink)

This paper presents an interpretation of Kant's analytic/ synthetic distinction and of the capacity he terms "sensibility" in order to offer a new account of Kant's claim that mathematics consists primarily of synthetic judgments which involve intuition. In Section 1, it is argued that the analytic/synthetic distinction is based upon a theory of concepts going back to Aristotle which sees these as organizable into genus/species hierarchies. Analytic judgments are those whose predicates are genus-related to the subject while synthetic judgments do (...) not exhibit a genus/species relation between the predicate and the subject of the judgment. Section 2 considers the nature of sensibility which is argued to involve the discernment of mereological relations. Mathematics is then seen to involve the formation of concepts of these relations.

Optimism has reigned supreme for a long time regarding the potential of education (schooling) to address the many societal ailments that humankind has had to deal with. The outbreak of the COVID-19 pandemic in March 2020 shifted all such aspirations to the back-burner. Now, after just more than a year after the initial outbreak of the pandemic, the question can be raised whether those who managed the pandemic in the educational context followed the correct policies and instituted the correct (ethical, (...) moral) measures in combatting the pandemic. This comparison between the situation in the Netherlands and South Africa reveals that although the role-players in both countries had a good understanding of the situation and of their duties in such conditions, they tended to treat education as just another facet of society, thereby demonstrating a lack of empathy with the unique demands of education (schooling). CONTRIBUTION: In this article, the authors investigate the governance performance of two different countries during the first year of the COVID-19 pandemic concerning education and judge that performance based on a Biblically driven ethical-moral-pedagogical framework.

Recent policy developments in the area of livestock husbandry have suggested that, from the perspective of optimizing animal welfare, new animal husbandry systems should be developed that provide opportunities for livestock animals to be raised in environments where they are permitted to engage in “natural behavior.” It is not known whether consumers regard animal husbandry issues as important, and whether they differentiate between animal husbandry and other animal welfare issues. The responsibility for the development of such systems is allocated jointly (...) between farmers, regulators, different actors in the food chain, and consumers. This research focuses on understanding consumer attitudes and preferences regarding the development and introduction of such systems, to ensure that they are acceptable to consumers as well as producers, regulators, and scientists. Consumer perceptions of animal welfare and animal husbandry practices were evaluated using quantitative consumer survey, which focused on two animal husbandry issues – farmed pigs and farmed fish. Following pilot work, 1000 representative Dutch consumers were sampled about their attitudes to either pig or fish husbandry. The results indicated that consumers think about animal welfare in terms of two broad categories related to their health and living environment, but do not think about welfare issues at a more detailed level. Greater concern was expressed about the welfare of pigs compared to fish. Consumer trust in labeling also emerged as an important issue, since consumers need to trust different food chain actors with responsibility for promoting animal welfare, and are reluctant to consider the details of animal husbandry systems. As a consequence, a transparent, enforceable, and traceable monitoring system for animal welfare friendly products is likely to be important for consumers. (shrink)

Recent results have shown that the relative activation of muscles is different for isometric contractions and for movements. These results exclude an explanation of muscle activation patterns by a combination ofreciprocal and coactivation commands. These results also indicate that joint stiffness is not uniquely determined and that it may be different for isometric contractions and movements.

Queen pheromones, which signal the presence of a fertile queen and induce daughter workers to remain sterile, are considered to play a key role in regulating the reproductive division of labor of insect societies. Although queen pheromones were long thought to be highly taxon‐specific, recent studies have shown that structurally related long‐chain hydrocarbons act as conserved queen signals across several independently evolved lineages of social insects. These results imply that social insect queen pheromones are very ancient and likely derived from (...) an ancestral signalling system that was already present in their common solitary ancestors. Based on these new insights, we here review the literature and speculate on what signal precursors social insect queen pheromones may have evolved from. Furthermore, we provide compelling evidence that these pheromones should best be seen as honest signals of fertility as opposed to suppressive agents that chemically sterilize the workers against their own best interests.

The ‘ars inveniendi’ of Cicero has been discussed in studies on Rhetoric, but hardly within the framework of philosophy. This article stresses its importance for philosophical reflection by analysing the ‘ars inveniendi’ in the works of Cicero and tracing its further development (Boethius, Agricola, Ramus). Its effect can be retraced in later philosophers who are using the topic of ‘ars inveniendi’, referring to Cicero, such as Bacon and Leibniz.

Introduction In 2007, a national review committee was instituted in The Netherlands to review cases of active ending of life for newborns. It was expected that 15–20 cases would be reported. To date, however, only one case has been reported to this committee. Reporting is essential to obtain societal control and transparency; the possible explanations for this lack of reporting were therefore explored. Methods Data on end-of-life decision-making were scrutinised from Dutch nation-wide studies (1995, 2001 and 2005), before institution of (...) the committee. Physicians received a questionnaire about their medical decision-making for stratified samples of deceased infants up to 1 year, drawn from the central death registry. Results In 2005, 58% of all deaths were preceded by an end-of-life decision, compared with 68% in 2001 and 62% in 1995. The use of drugs with a possible life-shortening effect tended to be lower. In 2005, all four cases in the study in which an infants' life was actively ended were preceded by a decision to forego life-prolonging treatment. In three cases, the infant's life expectancy was short; one case involved a longer life expectancy. Discussion The expected number of cases is probably an overestimation due to changes in medical practice such as the tendency to attribute less life-shortening effects to opioids. The lack of reports is probably also associated with requirements in the regulation; it may be difficult to fulfil them due either to time constraints or the nature of the suffering that is addressed. If societal control of active ending of life is considered useful, changes in the regulation may be needed. (shrink)

Genomic research results and incidental findings with health implications for a research participant are of potential interest not only to the participant, but also to the participant's family. Yet investigators lack guidance on return of results to relatives, including after the participant's death. In this paper, a national working group offers consensus analysis and recommendations, including an ethical framework to guide investigators in managing this challenging issue, before and after the participant's death.
