We discuss the case against Factorism, which is the standard assumption in quantum mechanics that the labels of the $$\otimes$$ ⊗ -factor Hilbert-spaces in direct-product Hilbert-spaces of composite physical systems of similar particles refer to particles, either directly or descriptively. We distinguish different versions of Factorism and argue for their truth or falsehood. In particular, by introducing the concepts of snapshot Hilbert-space and Schrödinger-movie, we demonstrate that there are Hilbert-spaces and $$\otimes$$ ⊗ -factorisations where the labels do refer, even descriptively, (...) to similar particles, which renders them probabilistically absolutely discernible.

The first clinical ethics committees in Norway were established in 1996. This started as an initiative from hospital clinicians, the Norwegian Medical Association, and health authorities and politicians. Norwegian hospitals are, by and large, publicly funded through taxation, and all inpatient treatment is free of charge. Today, all the 23 hospital trusts have established at least one committee. Center for Medical Ethics , University of Oslo, receives an annual amount of US$335,000 from the Ministry of Health and Care Services to (...) coordinate the committees and to facilitate competency building for committee members.

In his 2009 PSA Recent Ph.D. Award winning contribution to the bi-annual PSA Conference at Pittsburgh in 2008, C. Wu ̈thrich mounted an argument against struc- turalism about space-time in the context of the General Theory of Relativity, to the effect that structuralists cannot discern space-time points. An “abysmal embarrass- ment” for the structuralist, Wu ̈thrich judged. Wu ̈thrich’s characterisation of space-time structuralism is however incorrect. We demonstrate how, on the basis of a correct char- acterisation of space-time structuralism, it (...) is possible to discern space-time points in the GTR-structures under consideration. Thus Wu ̈thrich’s argument crumbles. (shrink)

On the History of Modern Philosophy is a key transitional text in the history of European philosophy. In it, F. W. J. Schelling surveys philosophy from Descartes to German Idealism and shows why the Idealist project is ultimately doomed to failure. The lectures trace the path of philosophy from Descartes through Spinoza, Leibniz, Kant, Fichte, Jacobi, to Hegel and Schelling's own work. The extensive critiques of Hegel prefigure many of the arguments to be found in Feuerbach, Kierkegaard, Marx, Nietzsche, Heidegger, (...) and Derrida. This is the first English translation of On the History of Modern Philosophy. In his introduction Andrew Bowie sets the work in the context of Schelling's career and clarifies its philosophical issues. The translation will be of special interest to philosophers, intellectual historians, literary theorists, and theologians. (shrink)

The notorious ‘measurement problem’ has been roving around quantum mechanics for nearly a century since its inception, and has given rise to a variety of ‘interpretations’ of quantum mechanics, which are meant to evade it. We argue that no less than six problems need to be distinguished, and that several of them classify as different types of problems. One of them is what traditionally is called ‘the measurement problem’. Another of them has nothing to do with measurements but is a (...) profound metaphysical problem. We also analyse critically Maudlin’s (Topoi 14:7–15, 1995) well-known statement of ‘three measurements problems’, and the clash of the views of Brown (Found Phys 16:857–870, 1986) and Stein (Maximal of an impossibility theorem concerning quantum measurement. In: R. S. Cohen et al. (Eds.), Potentiality, entanglement and passion-at-a-distance, 1997) on one of the six measurement problems. Finally, we summarise a solution to one measurement problem which has been largely ignored but tacitly if not explicitly acknowledged. (shrink)

All Canadian bioethicists need to reflect on the meaning and value of their work, to see more clearly how the ethics of bioethics is being undermined from within. In the case involving Dr Olivieri, the Hospital for Sick Children, the University of Toronto, and Apotex Inc, there were countless opportunities for bioethical heroism. And yet, no bioethics heroes emerged from this case. Much has been written about the hospital’s and the university’s failures in this case. But what about the deafening (...) silence from the Canadian bioethics community? Given the duty of bioethicists to “speak truth to power”, this silence is troubling. To date, nothing has been written about the silence. This article is intended as a partial remedy. As well, the article pays tribute to heretofore unsung heroes among Dr Olivieri’s research colleagues. (shrink)

F. H. Bradley (1846–1924) was the foremost philosopher of the British Idealist school, which came to prominence in the second half of the nineteenth century and remained influential into the first half of the twentieth. Bradley, who was influenced by Hegel and also reacted against utilitarianism, was recognised during his lifetime as one of the greatest intellectuals of his generation, and was the first philosopher to receive the Order of Merit, in 1924. In this major work, originally published in 1883, (...) Bradley discusses the basic principles of logic: judgment and inference. He rejects the idea of a separation between mind and body, arguing that human thought cannot be separated from its worldly context. In the second edition, published in 1922 and reissued here, Bradley added a commentary and essays, but left the text largely unaltered. Volume 1 contains Book 1 on judgment and Book 2 on inference.

The highly sophisticated techniques of modern engineering are normally conceived of in practical terms. Corresponding to the instrumental function of technology, they are designed to direct the forces of nature according to human purposes. Yet, as soon as the realm of mere skills is exceeded, the intended useful results can only be achieved through planned and preconceived action processes involving the deliberately considered application of well designed tools and devices. This is to say that in all complex cases theoretical reasoning (...) becomes an indispensable means to accomplish the pragmatic technological aims. Hence the abstracting from the actual concrete function of technology opens the way to concentrate attention on the general conceptual framework involved. If this approach is adopted the relevant knowledge and the procedures applied clearly exhibit a logic of their own. This point of view leads to a methodological and even an epistemological analysis of the theoretical structure and the specific methods of procedure characteristic of modern technology. Investigations of this kind, that can be described as belonging to an ana lytical philosophy of technology, form the topic of this anthology. The type of research in question here is closely akin to that of the philosophy of science. But it is an astonishing fact that the commonly accepted and carefully investigated philosophy of science has not yet found its counterpart in an established philosophy of technology. (shrink)

This is a book about the philosophy of Henri Bergson which shows how relevant Bergson is to much contemporary philosophy. The book takes as its point of departure Bergson's insistence on precision in philosophy. It then discusses a variety of topics including laughter, the nature of time as experienced, how intelligence and language should be construed as a pragmatic product of evolution, and the antinomies of reason represented by magic and religion. This is not just another exposition of Bergson's work. (...) It offers an account of why Bergson commanded such a massive reading public in his own day and why he deserves to be read now. Written in a terse and clear style, this book will prove appealing to teachers and students of philosophy, cognitive science, psychology, religious studies and literature. (shrink)

Zeller argued that the ‘innumerable worlds’ mentioned in accounts of Anaximander's system must be an endless succession of single worlds, not an unlimited number of coexistent worlds scattered through infinite space, some always coming into being while others are passing away. Zeller pointed out that a succession of single worlds is grounded in the principles of the system. ‘Things perish into that from which they had their birth… according to the order of Time,’ a cycle of birth, existence, and destruction. (...) A world ends, and the living divine stuff begets a new world to take its place. On the other hand, there is much in the system to contradict the idea of coexistent worlds. Anaximander's successors, Anaximenes, Anaxagoras, and Diogenes, show that this idea is not a necessary consequence of the unlimitedness of the original world-stuff. Nothing in the appearances of Nature suggests it. Anaximander is a monistic hylozoist, whereas Democritus is a pluralist with his innumerable independent atoms producing, by similar processes, independent world-systems in different parts of an infinite void.

The general context of this paper is the locality problem in quantum theory. In a recent issue of this journal, Redei (1991) offered a proof of the proposition that algebraic Lorentz-covariant quantum field theory is past stochastic Einstein local. We show that Redei's proof is either spurious or circular, and that it contains two deductive fallacies. Furthermore, we prove that the mentioned theory meets the stronger condition of stochastic Haag locality.

This paper is an attempt at a vindication of induction. The point of departure is that induction requires a justification and that the only kind of justification possible is a vindication. However traditional vindications of induction have rested on unjustified assumptions about the aim of induction. This vindication takes the end pursued in induction simply to be correct prediction. It is argued that induction is the only reasonable way of pursuing this end because induction is the only objective method of (...) predicting. While objectivity is not a necessary condition for successful predicting, it is a sufficient condition for the possession of a property that is, in turn, a necessary condition for correct predicting; and further there could be no reason to expect any non-objective method to possess this necessary condition for success. Induction is the only objective method of predicting for it alone uses facts which must be identified by any predicting method based on rules; and it alone uses these facts according to a relationship that must hold between facts and any meaningful empirical statement. Any alternative to induction must assume that the factual regularities that have been detected will alter in the future and the way they are expected to alter must be arbitrary. It is further claimed that this vindication is proof against the criticisms that have been advanced against practicalist justifications of induction. (shrink)

Diagnostic errors are more frequently a result of the clinician's failure to combine medical knowledge adequately than of data inaccuracy. Diagnostic reasoning studies are valuable to understand and improve diagnostic reasoning. However, most diagnostic reasoning studies are characterized by some limitations which make these studies seem more simple than diagnostic reasoning in real life situations actually is. These limitations are connected both to the failure to acknowledge components of knowledge used in clinical practice as well as to acknowledge the physician-patient (...) relationship's influence on clinical knowledge and on the reasoning process itself. In addition the modes of reasoning described in these studies frequently is oversimplified. In this paper three simplistic and competing models of diagnostic reasoning are analyzed and criticized, followed by an evaluation of two alternative models proposing a combined view. (shrink)

Objective: To pilot informed consent materials developed for Aboriginal parents in a vaccine trial, and evaluate their design and the informed consent process.Methods: Cross sectional quantitative and qualitative survey of 20 Aboriginal and 20 non-Aboriginal women in Alice Springs. Information about the proposed research was presented to Aboriginal participants by an Aboriginal researcher, using purpose designed verbal, visual, and written materials. Non-Aboriginal participants received standard materials developed by the sponsor. Questionnaires were used to evaluate recall and understanding immediately and five (...) days later. Qualitative analysis of Aboriginal participants’ interviews was performed.Results: There were no differences between the groups in understanding of diseases prevented by the vaccine, the potential risks of participating, or the voluntary nature of participation. Most Aboriginal participants had difficulty with the concept of a “licensed” versus “unlicensed” vaccine. The non-Aboriginal group had a good understanding of this. Aboriginal participants identified the use of the flipchart, along with a presentation by a doctor and Aboriginal health worker, as preferred delivery modes. Group presentations were preferred rather than one-on-one discussions. The use of the questionnaire posed considerable methodological difficulties.Conclusions: A one-off oral presentation to Aboriginal participants is unlikely to produce “informed consent”. Key but unfamiliar concepts require identification and particularly considered presentation. (shrink)

Reichenbach held that all scientific inference reduces, via probability calculus, to induction, and he held that induction can be justified. He sees scientific knowledge in a practical context and insists that any rational assessment of actions requires a justification of induction. Gaps remain in his justifying argument; for we can not hope to prove that induction will succeed if success is possible. However, there are good prospects for completing a justification of essentially the kind he sought by showing that while (...) induction may succeed, no alternative is a rational way of trying.Reichenbach's claim that probability calculus, especially via Bayes' Theorem, can help to exhibit the structure of inference to theories is a valuable insight. However, his thesis that the weighting of all hypotheses rests only on frequency data is too restrictive, especially given his scientific realism. Other empirical factors are relevant. Any satisfactory account of scientific inference must be deeply indebted to Reichenbach's foundation work. (shrink)

The object of this paper is to determine the relations between the two parts of Parmenides' poem: the Way of Truth, which deduces the necessary properties of a One Being, and the False Way, which contains a cosmogony based on ‘what seems to mortals, in which there is no true belief.’.
