In this work we analyze the case of resistive conductor plates carrying constant currents, utilizing surface charge distributions. We obtain the electric potential in the plates and in the space surrounding them. We obtain a non-vanishing electric field outside the conductors. We compare the theoretical results with experimental data present in the literature.

Warning research participants and patients about potential risks associated with participation/treatment is a fundamental part of consent. However, such risk warnings might cause negative expectations and subsequent nocebo effects (i.e., negative expectations cause negative outcomes) in participants. Because no existing review documents how past research has quantitatively examined nocebo effects – and negative expectations – arising from consent risk warnings, we conducted a pre-registered scoping review (N = 9). We identified several methodological issues across these studies, which in addition to (...) mixed findings, limit conclusions about whether risk warnings cause nocebo effects. (shrink)

Nous considérons la structure dans son rapport au temps : sous ce rapport, la structure est normative, et l’avenir aide à constituer le présent et le passé. Des exemples sont empruntés à l’embryologie et à la géologie. On explique pourquoi il est difficile de concevoir une structure cosmique spatio-temporelle, et comment le développement récent de la physique nous y aide ; dans cette physique, la notion de structure cosmique a un rôle éminent. Il en résulte que seules sont viables les (...) combinaisons qui sont dans La ligne historique de la nature. (shrink)

The subject is in both cases the voyage of the Argo, and therefore the use of the same words is not likely to be coincidental, even though the words themselves are scarcely uncommon. One would hesitate to deny, however, that such reminiscence might be unconscious; that Lucan had famous tags in his head is suggested by another allusion to famous opening lines.

What are physical quantities, and in particular, what makes them quantitative? This book presents an original answer to this question through the novel position of substantival structuralism, arguing that quantitativeness is an irreducible feature of attributes, and quantitative attributes are best understood as substantival structured spaces.

Limits to Action: The Allocation of Individual Behavior presents the ideas and methods in the study of how individual organisms allocate their limited time and energy and the consequences of such allocation. The book is a survey of individual resource allocation, emphasizing the relationships of the concepts of utility, reinforcement, and Darwinian fitness. The chapters are arranged beginning with plants and general evolutionary considerations, through animal behavior in nature and laboratory, and ending with human behavior in suburb and institution. Topics (...) discussed include operant conditioning; the principle of diminishing returns; and issues in relation to mating strategies. Biologists, sociologists, economists, and psychologists will find the book interesting. (shrink)

Although Professor of Philosophy at Calvin College, Alvin Plantinga has developed a theodicy that is fundamentally Arminian rather than Calvinistic. Anthony Flew, although the son of an Arminian Christian minister, regards the Arminian view of ‘free will’ to be both unacceptable on its own terms and incompatible with classical Christian theism. In this paper I hope to disentangle some of the involved controversy regarding theodicy which has developed between Plantinga and Flew, and between Flew and myself. The major portion of (...) this paper is devoted to showing that Plantinga's theodicy contains some serious flaws and undesirable implications. (shrink)

Measurement realism, the view that measurement targets quantitative attributes and that not all attributes are quantitative, has come under attack both from metrologists and philosophers. In this paper, I take a close look at two influential arguments against measurement realism: the argument from obsolescence and the argument from coordination. I concede that these arguments do challenge the epistemological position traditionally taken by measurement realists, but argue that the metaphysical core of measurement realism survives the challenge posed by these arguments. This (...) metaphysical core is vital to maintaining a clear and ambitious standard for successful measurement. (shrink)

It is standardly assumed that there are three — and only three — ways to solve problem of temporary intrinsics: (a) embrace presentism, (b) relativize property possession to times, or (c) accept the doctrine of temporal parts. The first two solutions are favoured by endurantists, whereas the third is the perdurantist solution of choice. In this paper, I argue that there is a further type of solution available to endurantists, one that not only avoids the usual costs, but is structurally (...) identical to the temporal-parts solution preferred by perdurantists. In addition to providing a general characterization of this new type of solution, I discuss certain of its anticipations in the literature on bundle theory, as well as provide a detailed development of it in terms of my own preferred metaphysics of ordinary objects — namely, a distinctive form of substratum theory tracing to Aristotle.

'To think often, and never to retain it so much as one moment, is a very useless sort of thinking' In An Essay concerning Human Understanding, John Locke sets out his theory of knowledge and how we acquire it. Eschewing doctrines of innate principles and ideas, Locke shows how all our ideas, even the most abstract and complex, are grounded in human experience and attained by sensation of external things or reflection upon our own mental activities. A thorough examination of (...) the communication of ideas through language and the conventions of taking words as signs of ideas paves the way for his penetrating critique of the limitations of ideas and the extent of our knowledge of ourselves, the world, God, and morals. Locke's masterpiece laid the foundation of British empiricism and is of enduring interest to anyone exploring the development of philosophical thought. This sensitive abridgement uses P. H. Nidditch's authoritative text, and together with an illuminating introduction and other features, makes Locke's arguments more accessible. (shrink)

The end of World War II marked the beginning of a new chapter in German Leibniz scholarship, with conferences all over the country gearing up to commemorate the 300th anniversary of his birth in 1946, and participants intent on promoting Leibniz as a pan-European thinker. Just a few years earlier, for obvious reasons, the outlook could not have been more different. To take one example, Oskar Becker, in his lecture, “Leibniz, the German Thinker and Good European,” had divided the different (...) versions of Leibniz up along strictly national lines: “In the international Leibniz literature of today the different aspects of his philosophy… are shown in the views of one nation from this, of another nation from that side. Thus for the West European scholars Louis Couturat and Bertrand Russell Leibniz is fundamentally a logician, while for the Germans he is fundamentally a metaphysician.”. (shrink)
