Within many approaches to the interpretation of quantum mechanics, especially modal interpretations, one singles out a particular decomposition of the state vector in order to fix the properties that are well-defined for the system. We present a novel proposal for this preferred decomposition. Given a distinguished factorization of the Hilbert space, it is the decomposition that minimizes the Ingarden–Urbanik entropy from among all product decompositions with respect to the distinguished factorization. We incorporate this choice of preferred decomposition into a framework (...) for modal interpretations and investigate in detail the extent to which it provides a solution to the measurement problem and the extent to which it ensures that measurements whose outcomes are predictable with probability 1 reveal pre-existing properties of the system under investigation.

Modal interpretations constitute a particular approach to associating dynamical variables with physical systems in quantum mechanics. Given the “quantum logical” constraints that are typically adopted by such interpretations, only certain sets of variables can be taken to be simultaneously definite-valued, and only certain sets of values can be ascribed to these variables at a given time. Moreover, each allowable set of variables and values can be uniquely specified by a single “core” projector in the Hilbert space associated with the system. (...) In general, the core projector can be one of several possibilities at a given time. In most previous modal interpretations, the different possible core projectors have formed an orthogonal set. This paper investigates the possibility of adopting a non-orthogonal set. It is demonstrated that such non-orthogonality is required if measurements for which the outcome can be predicted with probability 1 are to reveal the pre-existing value of the variable measured, an assumption which has traditionally constituted a strong motivation for the modal approach. The existing framework for modal interpretations is generalized to explicitly accommodate non-orthogonal core projectors. (shrink)

The Hellenistic philosophers and schools of philosophy are emerging from the shadow of Plato and Aristotle and are increasingly studied for their intrinsic philosophical value. They are not only interesting in their own right, but also form the intellectual background of the late Roman Republic. This study gives a comprehensive and readable account of the principal doctrines of the Stoics, Epicureans and various sceptical traditions from the death of Alexander the Great in 323 B.C. to around 200 A.D. Discussions are (...) arranged topically in order to address underlying issues and to make clear what the different schools have in common and how they differ. At the same time the coherence of each system as a whole is emphasized. (shrink)

This book critically examines the case for and against the belief in personal survival of bodily death. It discusses key philosophical questions. How could a discarnate individual be identified as a person who was once alive? What is the relationship between minds and their brains? Is a 'next world' conceivable? The book also examines classic arguments for the immortality of the soul, and focuses on types of prima facie evidence of survival: near-death experiences, apparitions, mediumistic communications, and ostensible reincarnation cases.

This is the second of the three volumes comprising, Scholastic Humanism and the Unification of Europe. Focussing on the period from c.1090-1212, the volume explores the lives, scholarly resources, and contributions of a wide sample of people who either took part in the creation of the scholastic system of thought or gave practical effect to it in public life. The second volume of a compelling, original work which will redefine our perceptions of medieval civilization, the renaissance and the evolution of (...) modern Europe. Written by a man who was widely regarded as the greatest medieval historian. (shrink)

This book provides a collection of sources, many of them fragmentary and previously scattered and hard to access, for the development of Peripatetic philosophy in the later Hellenistic period and the early Roman Empire. It also supplies the background against which the first commentator on Aristotle from whom extensive material survives, Alexander of Aphrodisias (fl. c. AD 200), developed his interpretations which continue to be influential even today. Many of the passages are here translated into English for the first time, (...) including the whole of the summary of Peripatetic ethics attributed to 'Arius Didymus'. (shrink)

This paper critically examines the claim that parallel distributed processing (PDP) networks are autonomous learning systems. A PDP model of a simple distributed associative memory is considered. It is shown that the 'generic' PDP architecture cannot implement the computations required by this memory system without the aid of external control. In other words, the model is not autonomous. Two specific problems are highlighted: (i) simultaneous learning and recall are not permitted to occur as would be required of an autonomous system; (...) (ii) connections between processing units cannot simultaneously represent current and previous network activation as would be required if learning is to occur. Similar problems exist for more sophisticated networks constructed from the generic PDP architecture. We argue that this is because these models are not adequately constrained by the properties of the functional architecture assumed by PDP modelers. It is also argued that without such constraints, PDP researchers cannot claim to have developed an architecture radically different from that proposed by the Classical approach in cognitive science. (shrink)

PDP networks that use nonmonotonic activation functions often produce hidden unit regularities that permit the internal structure of these networks to be interpreted (Berkeley et al., 1995; McCaughan, 1997; Dawson, 1998). In particular, when the responses of hidden units to a set of patterns are graphed using jittered density plots, these plots organize themselves into a set of discrete stripes or bands. In some cases, each band is associated with a local interpretation. On the basis of these observations, Berkeley (2000) (...) has suggested that these bands are both subsymbolic and symbolic in nature, and has used the analysis of one network to support the claim that there are fewer differences between symbols and subsymbols than one might expect. We suggest below that this conclusion is premature. First, in many cases the local interpretation of each band is difficult to relate to the interpretation of a network's response; a more appropriate relationship only emerges when a band associated with one hidden unit is considered in the context of other bands associated with other hidden units (i.e., interpretations of distributed representations are more useful than interpretations of local representations). Second, the content that a band designates to an external observer (i.e., the interpretation assigned to a band by the researcher) can be quite different from the content that a band designates to the output units of the network itself.. We use two different network simulations – including the one described by Berkeley (2000) – to illustrate these points. We conclude that current evidence involving interpretations of nonmonotonic PDP networks actually illustrates the differences between symbolic and subsymbolic processing. (shrink)

Claims about ‘the meaning of life’ have tended to be made and discussed in conjunction with bold metaphysical and theological affirmations. For life to have meaning, there must be a comprehensive divine plan to give it meaning, or there must be an intelligible cosmic process with a ‘telos’ that a man needs to know if his life is to be meaningfully orientated. Or, it is thought to be a condition of the meaningfulness of life, that values should be ultimately ‘conserved’ (...) in some way, that no evil should be unredeemable and irrational. And it may be claimed that if death were to end our experience, meaninglessness would triumph. (shrink)

This paper examines whether a classical model could be translated into a PDP network using a standard connectionist training technique called extra output learning. In Study 1, standard machine learning techniques were used to create a decision tree that could be used to classify 8124 different mushrooms as being edible or poisonous on the basis of 21 different Features (Schlimmer, 1987). In Study 2, extra output learning was used to insert this decision tree into a PDP network being trained on (...) the identical problem. An interpretation of the trained network revealed a perfect mapping from its internal structure to the decision tree, representing a precise translation of the classical theory to the connectionist model. In Study 3, a second network was trained on the mushroom problem without using extra output learning. An interpretation of this second network revealed a different algorithm for solving the mushroom problem, demonstrating that the Study 2 network was indeed a proper theory translation. (shrink)

This study describes the level of moral sensitivity among nursing students enrolled in a traditional baccalaureate nursing program and a master’s nursing program. Survey responses to the Modified Moral Sensitivity Questionnaire for Student Nurses from 250 junior, senior, and graduate students from one nursing school were analyzed. It was not possible to draw conclusions based on the tool. Moral category analysis showed students ranked the category structuring moral meaning highest and interpersonal orientation second. The moral issue ranking highest was honesty, (...) respect for the patient second, and third was responsibility to know the patient’s situation. Seniors agreed more often about the need to focus on patient safety. As students progress through the baccalaureate program and into the graduate program, their perspectives increasingly recognize the contextuality of moral issues. The results show a need to further develop a tool to measure moral sensitivity, using student understanding and perceptions of moral issues. (shrink)

Nerve cells - neurons - are arguably the most complex of all cells. From the action of these cells comes movement, thought and consciousness. It is a challenging task to understand what molecules direct the various diverse aspects of their function. This has produced an ever-increasing amount of molecular information about neurons, and only in Molecular Biology of the Neuron can a large part of this information be found in one source. In this book, a non-specialist can learn about the (...) molecules that control information flow in the brain or the progress of brain disease in an approachable format, while the expert has access to a wealth of detailed information from a wide range of topics impacting on his or her field of endeavour. The text is designed to achieve a balance of accessibility and broad coverage with up-to-date molecular detail. In the six years since the first edition of Molecular Biology of the Neuron there has been an explosion in the molecular information about neurons that has been discovered, and this information is incorporated into this second edition. Entirely new chapters have been introduced where recent advances have made a new aspect of neuronal function more comprehensible at the molecular level. Written by leading researchers in the field, the book provides an essential overview of the molecular structure and function of neurons, and will be an invaluable tool to students and researchers alike.

There are numerous ‘solutions’ to the problem of evil, from which theists can and do freely take their pick. It is fairly clear that any attempt at a solution must involve a scaling-down of one or more of the assertions out of whose initial conflict the problem arises – either by a downward revision of what we mean by omnipotence, or omniscience, or benevolence, or by minimizing the amount or condensing the varieties of evil actually to be found in the (...) universe. And indeed, in one or more of these different ways, the charge of logical inconsistency can no doubt always be vouchsafed at least a formal answer. Unfortunately, the mere ironing-out of formal inconsistencies does not of itself go very far towards providing a solution to this central problem of theism which will be morally, religiously, and intellectually convincing and acceptable as well as logically impeccable. Everything depends on how the inconsistencies are ironed out. For every attempt at a solution of the problem of evil has to be made at a price, in keeping with the scale and type of conceptual or ethical readjustments which it requires of us. And if the solutions which are generally offered seldom seem to carry much conviction, this is because the price they require us to pay nearly always seems far too high. A ‘solution’ to the problem of evil that is to count as a genuine solution must not require us to make any conceptual or ethical readjustments which it would not on independent grounds be entirely reasonable to make. A ‘solution’ that was finally to count as the solution of the problem of evil would presumably need to be that particular one which required us to make only those conceptual and ethical readjustments which were on independent grounds the ones that it was the most reasonable to make. What follows is offered as a solution, in the above sense, of the problem of evil. However, I shall not here attempt to argue that it is the solution. (shrink)

Most readers will agree with the starting assumptions of Klee that contemporary science and philosophy assume a primarily micro-deterministic view of nature–and that this has long been the case, or was at least until the 1970s. Defending a strict micro-determinism, Klee argues that concepts of emergence that seemingly are opposed to micro-determinist doctrine can be shown, on analysis, to be ultimately consistent with a thoroughgoing philosophy of micro-determinism. An exception is made, however, in the case of my own view, labeled (...) “direct macro-determinism,” which he describes as “ultimately more troublesome” but then disposes of as being based on “simplistic analogies” and “metaphors” and “too weak to be conclusive.”.

In an important article in the opening issue of Religious Studies , Professor H. H. Price states that: ‘Epistemologists have not usually had much to say about believing “in”, though ever since Plato's time they have been interested in believing “that”’ . We are all considerably in debt to Professor Price for his extremely lucid analysis which will, I think, go a very long way towards filling the lacuna to which he points. As I find myself in agreement with almost (...) every point which Price has made, my purpose here is not to make a ‘reply’ to his article in the usual sense but to suggest that his analysis of believing is curiously and disappointingly incomplete. I shall offer some reasons of my own in support of this suggestion, not so much in criticism of Price's thesis as in hopes of finding some way out of the difficulties which, I take it, forced Price to stop short just where he did. It will be the burden of my argument to show that a more complete and satisfactory account of believing must include a description of its ‘metaphysical element’ as well as of its epistemological and psychological conditions. For it is at the point of what I shall call the ‘metaphysics of believing’ that Price's analysis and description of belief ‘in’ and belief ‘that’ stops short. 1. (shrink)
