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.

We inquire into the question whether the Aristotelean or classical \emph{ideal} of science has been realised by the Model Revolution, initiated at Stanford University during the 1950ies and spread all around the world of philosophy of science --- \emph{salute} P.\ Suppes. The guiding principle of the Model Revolution is: \emph{a scientific theory is a set of structures in the domain of discourse of axiomatic set-theory}, characterised by a set-theoretical predicate. We expound some critical reflections on the Model Revolution; the conclusions (...) will be that the philosophical problem of what a \emph{scientific theory} is has \emph{not} been solved yet --- \emph{pace} P.\ Suppes. While reflecting critically on the Model Revolution, we also explore a proposal of how to complete the Revolution and briefly address the intertwined subject of \emph{scientific representation}, which has come to occupy center stage in philosophy of science over the past decade.

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)

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)

With a new foreword by Paul Kelly 'I regard Hayek's work as a new opening of the most fundamental debate in the field of political philosophy' - Sir Karl Popper 'This promises to be the crowning work of a scholar who has devoted a lifetime to thinking about society and its values. The entire work must surely amount to an immense contribution to social and legal philosophy' - Philosophical Studies Law, Legislation and Liberty is Hayek's major statement of political philosophy (...) and one of the most ambitious yet subtle defences of a free market society ever written. A robust defence of individual liberty, it is also crucial for understanding Hayek's influential views concerning the role of the state: far from being an innocent bystander, he argues that the state has an important role to play in defending the norms and practices of an ordered and free society. His arguments had a profound influence on the policies of Thatcher in the 1980s and resonate today in visions of the 'Big Society'. First published in three separate volumes, this Routledge Classics edition makes one of his most important books available in a single volume. Essential reading for understanding the background to the recent world economic turmoil and financial crisis, it also foreshadows the subsequent heated debate about regulation and political governance if such disasters are to be avoided in the future.

Peirce and Frege both distinguished between the propositional content of an assertion and the assertion of a propositional content, but with different notational means. We present a modification of Peirce’s graphical method of logic that can be used to reason about assertions in a manner similar to Peirce’s original method. We propose a new system of Assertive Graphs, which unlike the tradition that follows Frege involves no ad hoc sign of assertion. We show that axioms of intuitionistic logic can be (...) derived from AGs, and argue that AGs analyse and represent assertions and illocutionary content in a way which is motivated both by its logical properties and its historical connection with the ideas that led to the development of the graphical method.

The chronic worldwide lack of organs for transplantation and the continuing improvement of strategies for in situ organ preservation have led to renewed interest in elective non-therapeutic ventilation of potential organ donors. Two types of situation may be eligible for elective intensive care: patients definitely evolving towards brain death and patients suitable as controlled non-heart beating organ donors after life-supporting therapies have been assessed as futile and withdrawn. Assessment of the ethical acceptability and the risks of these strategies is essential. (...) We here offer such an ethical assessment using the four principles of medical ethics of Beauchamp and Childress applying them in their broadest sense so as to include patients and their families, their caregivers, other potential recipients of intensive care, and indeed society as a whole. The main ethical problems emerging are the definition of beneficence for the potential organ donor, the dilemma between the duty to respect a dying patient's autonomy and the duty not to harm him/her, and the possible psychological and social harm for families, caregivers other potential recipients of therapeutic intensive care, and society more generally. Caution is expressed about the ethical acceptability of elective non-therapeutic ventilation, along with some proposals for precautionary measures to be taken if it is to be implemented. (shrink)

Hayek's substantial contribution to theoretical psychology has been addressed in the work of Thomas Szasz, Gerald Edelman, and Joaquin Fuster.

We maximally extend the quantum‐mechanical results of Muller and Saunders ( 2008 ) establishing the ‘weak discernibility’ of an arbitrary number of similar fermions in finite‐dimensional Hilbert spaces. This confutes the currently dominant view that ( A ) the quantum‐mechanical description of similar particles conflicts with Leibniz’s Principle of the Identity of Indiscernibles (PII); and that ( B ) the only way to save PII is by adopting some heavy metaphysical notion such as Scotusian haecceitas or Adamsian primitive thisness. We (...) take sides with Muller and Saunders ( 2008 ) against this currently dominant view, which has been expounded and defended by many. *Received July 2008; revised May 2009. †To contact the authors, please write to: F.

Portraits of Wittgenstein is a major collection of memoirs and reflections on one of the most influential and yet elusive personalities in the history of modern philosophy, Ludwig Wittgenstein. Featuring a wealth of illuminating and profound insights into Wittgenstein's extraordinary life, this unique collection reveals Wittgenstein's character and power of personality more vividly and comprehensively than ever before. With portraits from more than seventy-five figures, Portraits of Wittgenstein brings together the personal recollections of philosophers, students, friends and acquaintances, including Bertrand (...) Russell, G. E. Moore, F. R. Leavis, A. J. Ayer, Karl Popper, Friedrich von Hayek, G. H. von Wright, Rush Rhees, Freeman Dyson, G. E. M. Anscombe, Iris Murdoch, Mary Midgley and Mary Warnock. These authors testify to the life-long influence Wittgenstein had on the lives of those he met. Their fascinating memoirs, reflections and commentaries, often at odds with each other, reveal Wittgenstein's kindness, and how much genuine friendship meant to him, as well as his suffering and despair. They show too how the philosopher's ruthless honesty and uncompromising integrity often resulted in stern advice and harsh rebukes to friends and foes alike. Now available in a single, revised and updated volume, Portraits of Wittgenstein includes new selections, revised contributions, photographs, maps and introductory overviews that provide historical context to Wittgenstein's relationships with his intellectual and social circle. This collection of valuable and hard-to-find material is an indispensable resource for scholars and students of the life and work of Ludwig Wittgenstein. (shrink)

By focussing on the intentional character of observation in science, we argue that Constructive Empiricism—B.C. van Fraassen’s much debated and explored view of science—is inconsistent. We then argue there are at least two ways out of our Inconsistency Argument, one of which is more easily to square with Constructive Empiricism than the other.

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.

Much research effort has been directed in different physiological contexts towards describing realistic behaviors with differential equations. One observes obviously that more state-variables give the model more accuracy. Unfortunately, the computational cost involved is higher. A new algorithm is presented for simulating a model described by a system of differential equations in which efficiency may not be altered by its size. In order to do this, the method is based on a polynomial description of the state-variables' evolution and on a (...) computation distributed control. Evaluations and results performed with classical models like Fitzhugh Nagumo or Hodgkin Huxley, allow validation of the method and exhibits its potential to decrease the computational costs.

Researchers have identified the phenomena of moral distress through many studies in Western countries. This research reports the first study of moral distress in Iran. Because of the differences in cultural values and nursing education, nurses working in intensive care units may experience moral distress differently than reported in previous studies. This research used a qualitative method involving semistructured and in-depth interviews of a purposive sample of 31 (28 clinical nurses and 3 nurse educators) individuals to identify the types of (...) moral distress among clinical nurses and nurse educators working in 12 cities in Iran. A content analysis of the data produced four themes to describe the nurses’ moral distress. The four themes were as follows: (a) institutional barriers and constraints; (b) communication problems; (c) futile actions, malpractice, and medical/care errors; (d) inappropriate responsibilities, resources, and competencies. The results demonstrate that moral distress for intensive care unit nurses is different and that the nursing leaders must reduce moral distress among nursing in intensive care. (shrink)

The use of human fetal tissue for scientific research has enormous potential but is subject to government legislation. In the United Kingdom the Polkinghorne Committee's guidelines were accepted by the Department of Health in 1990. These guidelines set out to protect women undergoing termination of pregnancy from exploitation but in so doing may significantly restrict potential research. Although the committee took evidence from a wide variety of experts they did not seek the views of the general public. We asked 108 (...) women about to have a therapeutic abortion; 167 women who had had a pregnancy terminated in the past, and 419 women who had never had an abortion, their views on research using human fetal tissue. Regardless of their past experiences the women were overwhelmingly in favour of research using fetal tissue (94 per cent). They made little distinction between basic research and research with obvious clinical relevance and supported the concept of using transplanted fetal tissue for the treatment of adult disease such as Parkinsonism. Women about to undergo an abortion were significantly more likely (p < 0.001) to approve of all types of research including that aimed at improving methods of abortion and research using live fetuses in utero.
