The covariant Klein-Gordon equation requires twice the boundary conditions of the Schrödinger equation and does not have an accepted single-particle interpretation. Instead of interpreting its solution as a probability wave determined by an initial boundary condition, this paper considers the possibility that the solutions are determined by both an initial and a final boundary condition. By constructing an invariant joint probability distribution from the size of the solution space, it is shown that the usual measurement probabilities can nearly be recovered (...) in the non-relativistic limit, provided that neither boundary constrains the energy to a precision near ℏ/t 0 (where t 0 is the time duration between the boundary conditions). Otherwise, deviations from standard quantum mechanics are predicted. (shrink)

A time-symmetric formulation of nonrelativistic quantum mechanics is developed by applying two consecutive boundary conditions onto solutions of a time- symmetrized wave equation. From known probabilities in ordinary quantum mechanics, a time-symmetric parameter P0 is then derived that properly weights the likelihood of any complete sequence of measurement outcomes on a quantum system. The results appear to match standard quantum mechanics, but do so without requiring a time-asymmetric collapse of the wavefunction upon measurement, thereby realigning quantum mechanics with an important (...) fundamental symmetry.

Mind uploading speculation and debate often concludes that a procedure described as gradual in-place replacement preserves personal identity while a procedure described as destructive scan-and-copy produces some other identity in the target substrate such that personal identity is lost along with the biological brain. This paper demonstrates a chain of reasoning that establishes metaphysical equivalence between these two methods in terms of preserving personal identity.

Background: Emergency exception to informed consent regulation was introduced to provide a venue to perform research on subjects in emergency situations before obtaining informed consent. For a study to proceed, institutional review boards need to determine if the regulations have been met.Aim: To determine IRB members’ experience reviewing research protocols using emergency exception to informed consent.Methods: This qualitative research used semistructured telephone interviews of 10 selected IRB members from around the US in the fall of 2003. IRB members were chosen (...) as little is known about their views of exception to consent, and part of their mandate is the protection of human subjects in research. Interview questions focused on the length of review process, ethical and legal considerations, training provided to IRB members on the regulations, and experience using community consultation and notification. Content analysis was performed on the transcripts of interviews. To ensure validity, data analysis was performed by individuals with varying backgrounds: three emergency physicians, an IRB member and a layperson.Results: Respondents noted that: emergency exception to informed consent studies require lengthy review; community consultation and notification regulations are vague and hard to implement; current regulations, if applied correctly, protect human subjects; legal counsel is an important aspect of reviewing exception to informed-consent protocols; and IRB members have had little or no formal training in these regulations, but are able to access materials needed to review such protocols.Conclusions: This preliminary study suggests that IRB members find emergency exception to informed consent studies take longer to review than other protocols, and that community consultation and community notification are the most difficult aspect of the regulations with which to comply but that they adequately protect human subjects.

This volume brings together flux essays by an eminent scholar on the origins, development, and import of Kant's philosophy, chiefly in its metaphysical aspects. Four of these were separately published between 1924 and 1926, but until now have been difficult to obtain, despite great demand. Their appearance here will be welcomed. The thesis emerging from these studies is that the critical philosophy originates in metaphysical probings concerning the nature and presuppositions of being, and issues in doctrines which, despite psychological, epistemological, (...) and ethical presentation, are intended to have definite ontological import. --L.

Provider claims to conscientious objection have generated a great deal of heated debate in recent years. However, the conflicts that arise when providers make claims to the "conscience" are only a subset of the more fundamental challenges that arise in health care practice when patients and providers come into conflict. In this piece, the author provides an account of patient-provider conflict from within the moral tradition of St. Thomas Aquinas. He argues that the practice of health care providers should be (...) understood as a form of practical reasoning and that this practical reasoning must necessarily incorporate both "moral" and "professional" commitments. In order to understand how the practical reasoning of provider should account for the needs and commitments of the patient and vice versa, he explores the account of dependence provided by Alasdair MacIntyre in his book Dependent Rational Animals. MacIntyre argues that St. Thomas’ account of practical reasoning should be extended and adapted to account for the embodied vulnerability of all humans. In light of this insight, providers must view patients not only as the subjects of their moral reflection but also as fellow humans upon whom the provider depends for feedback on the effectiveness and relevance of her practical reasoning. The author argues that this account precludes responsive providers from adopting either moral or professional conclusions on the appropriateness of interventions outside the individual circumstances that arise in particular situations. The adoption of this orientation toward patients will neither eradicate provider-patient conflict nor compel providers to perform interventions to which they object. But this account does require that providers attend meaningfully to the suffering of patients and seek feedback on whether their intervention has effectively addressed that suffering. (shrink)

A collection of six unrelated articles by as many authors. First come three scholarly studies, dealing with causality in Aristotle, St. Augustine's metaphysics of created being, and St. Thomas as a commentator on Aristotle. The fourth is an exposition of Hegel's views on scepticism. Next comes a reconstruction, within the scholastic spirit, of "classical formal logic." The concluding and most interesting article is a bibliographical survey of recent works in the history of ancient philosophies. --L. K. B.

Part of a series on Spanish philosophy, this work presents medieval Islamic philosophy from an unusual and consciously restricted perspective. This is most evident in the distribution of emphasis: Al-Kindi, Al-Zarabi, Algazel, even Avicenna are considered in the brief introductory discussion of "Oriental" Islamic philosophy, while the system of Averroes is treated in great detail as the culmination of a distinctly Spanish tradition. Not a definitive history of the subject, but a "scientific manual" of the present state of historical-philosophical knowledge, (...) based on available bibliographies and edited texts, this work will nevertheless serve many as a valuable and authoritative reference source on a neglected chapter in the history of ideas.--L.

A sympathetic exposition, carefully documented, of the meaning and function of aesthetic concepts in the Enneads. The Plotinian dialectic is compared to the artistic process. Aesthetic experience is found analogous to the mystical, and artistic intuition similar to ecstasy.--L.K.B.

A remarkably condensed statement of the main features of Ortega's philosophy, organized "biographically" around three stages of his intellectual development, termed "objectivism," "perspectivism," and "ratio-vitalism," with chief attention given to the last. The presentation is marked by a soberness unusual in writers on Ortega. As a result, a certain fairness and balance are achieved, yet not at the cost of any adequacy to the vitality of Ortega's own thought.--L. K. B.

A philological examination of the text of the Pensées.--L. K. B.

The report of a special commission engaged by the National Book Committee, Inc. to make an inquiry into the theory of censorship and the freedom to read. It presents 1. a philosophical, sociological, and legal analysis of the grounds and implications of censorship, 2. recommendations concerning the needed systematic empirical investigation into the effects of books, the formation of reading taste, etc., and 3. suggestions as to immediate action.--L.

There is a great deal of interest in the relation between the status of women and fertility—by humanists, academics and policy-makers concerned with bringing about fertility declines. The three aspects of women's status most frequently linked to fertility are their education, employment and type of husband-wife interaction. Research to date has not given us a clear and consistent explanation of these relationships and has not confirmed causality. The effects of these three factors on fertility vary considerably across national boundaries and (...) even within different sectors of the same society. Some of the assumptions held by both researchers and policymakers must be re-thought in the interests of more useful future research and of sounder policy. (shrink)

The wounds inflicted by Homer's warriors fascinate readers, since they are vividly described and often curious or even grotesque. Commentators have struggled to explain some of them since commentaries began: some of the explanations are more curious than the wounds. Not surprisingly, the commentaries have not usually been graced by a high standard of anatomical or, especially, physiological background knowledge, and are often misleading in these respects. When such knowledge is applied, some wounds which have appeared problematic become realistic, but (...) some which have been accepted as straightforward become problematic. (shrink)
