In orthodox quantum mechanics, it has virtually become the custom to identify properties of a physical system with operationally testable propositions about the system. The causes and consequences of this practice are explored mathematically in this paper. Among other things, it is found that such an identification imposes severe constraints on the admissible states of the physical system.

Piron's axioms for a realistically interpreted quantum mechanics are analyzed in detail within the context of a formal mathematical structure expressed in the conventional set-theoretic idiom of mathematics. As a result, some of the serious misconceptions that have encouraged recent criticisms of Piron's axioms are exposed.

Applied Christian Ethics addresses selected themes in Christian social ethics. Part one shows the roots of contributors in the realist school; part two focuses on different levels of the significance of economics for social justice; and part three deals with both existential experience and government policy in war and peace issues.

Background: Electroconvulsive therapy is one of the most effective treatments for major depressive disorder. Recently, there has been increasing attention to evaluate the effect of ECT on resting-state functional magnetic resonance imaging. This study aims to compare rs-fMRI of depressive disorder patients with healthy participants, investigate whether pre-ECT dynamic functional network connectivity network estimated from patients rs-fMRI is associated with an eventual ECT outcome, and explore the effect of ECT on brain network states.Method: Resting-state functional magnetic resonance imaging data were (...) collected from 119 patients with depression or depressive disorder, and 61 healthy participants, with an age mean of 52.25 years old. The pre-ECT and post-ECT Hamilton Depression Rating Scale were 25.59 ± 6.14 and 11.48 ± 9.07, respectively. Twenty-four independent components from default mode and cognitive control network were extracted, using group-independent component analysis from pre-ECT and post-ECT rs-fMRI. Then, the sliding window approach was used to estimate the pre-and post-ECT dFNC of each subject. Next, k-means clustering was separately applied to pre-ECT dFNC and post-ECT dFNC to assess three distinct states from each participant. We calculated the amount of time each subject spends in each state, which is called “occupancy rate” or OCR. Next, we compared OCR values between HC and DEP participants. We also calculated the partial correlation between pre-ECT OCRs and HDRS change while controlling for age, gender, and site. Finally, we evaluated the effectiveness of ECT by comparing pre- and post-ECT OCR of DEP and HC participants.Results: The main findings include depressive disorder patients had significantly lower OCR values than the HC group in state 2, where connectivity between cognitive control network and default mode network was relatively higher than other states, Pre-ECT OCR of state, with more negative connectivity between CCN and DMN components, is linked with the HDRS changes. This means that those DEP patients who spent less time in this state showed more HDRS change, and The post-ECT OCR analysis suggested that ECT increased the amount of time DEP patients spent in state 2.Conclusion: Our finding suggests that dynamic functional network connectivity features, estimated from CCN and DMN, show promise as a predictive biomarker of the ECT outcome of DEP patients. Also, this study identifies a possible underlying mechanism associated with the ECT effect on DEP patients. (shrink)

Hahn held on February 19, 2005, and were compiled for presentation here by Sharon (Hahn) Crowell.A Tribute to Dr. Lewis E. Hahn (1908-2004) from a Global PerspectiveGeorge C. H. Sun President, Thomé H. Fang Institute, Inc., Mobile, AlabamaAmong the philosophical community in both the East and the West, no word of introduction is needed for our beloved Master, who was the recipient of numerous distinctions and honors, with titles that included "Man of the Year in Philosophy" and "Award of Lifetime Achievement." The very name "Lewis E. Hahn" itself already stands now for genuineness, dedication, and fulfillment.A great work is a dialogue with eternity; a great person is such a work. In less than thirty years he succeeded in developing Carbondale from what had been a small college town in the Midwest into the Mecca of American philosophy. His most important achievements were the Dewey Center and the Pepper Archives that he helped install at SIUC These, among other such institutions, will remain a unique contribution, a glory of American philosophy, and a monument in the history of human thought.For posterity Lewis E. Hahn will remain an object of wonder and amazement. How is it possible for one human being to have accomplished so much, so well, and in so short a span of time—less than one century—in breadth, depth, and diversity? Some one hundred years ago, by bridging the gap between the New World and the Old, William James was hailed as the great genius of international friendship among philosophical thinkers, but we now find a greater genius in Lewis E. Hahn, who succeeded in bringing together the peoples of East and West from at least four continents: Europe, Australia, America (both North and Latin America), and Asia. To my knowledge, few of his predecessors and contemporaries have been half so widely read and liberal-minded as he was, in view of the range and scope of the Library of Living Philosophers that he helped continue after the passing of its founder, Dr. Paul A. Schilpp.What type of man was Hahn, our younger generation will wonder? Only a pluralist approach can help us understand the true character of such a legendary pluralist-contextualist. In short, he was "a full personality." As I recall, while working on my dissertation with him in the 1970s, we had a brief discussion on Confucius, the sage of ancient China. "A full personality!" was his laconic assessment. Suddenly I realized, to quote the Analects: "The Master is talking about himself!" For, as the Buddhists put it, only a Buddha can understand a Buddha. Or, as William James put it, only one who has philosophy can appreciate philosophy. Many friends [End Page 1] of my generation admire him so much; Te Chen of Hong Kong calls him "a great Confucian in America." Those who regret the loss of many precious Confucian virtues in China today have now rediscovered them in the person of Lewis E. Hahn! If Nietzsche called Kant "a great Chinese in Königsberg," it is simply because he had not encountered our own Master.A paradigm of academic leadership, Dr. Hahn is simply irreplaceable—this is a tribute I personally heard in Carbondale in the late 1960s. It is not an exaggeration to say that he was a superb administrator, and he could have been the best Secretary of the State we ever had, for he possessed more in the way of philosophical wisdom than all his predecessors put together! As a great teacher, he was no less "serene, good, learned, wise, and ardent" than... (shrink)

The prefrontal cortex is widely believed to play an important role in facilitating people's ability to switch performance between different tasks. We present a biologically‐based computational model of prefrontal cortex (PFC) that explains its role in task switching in terms of the greater flexibility conferred by activation‐based working memory representations in PFC, as compared with more slowly adapting weight‐based memory mechanisms. Specifically we show that PFC representations can be rapidly updated when a task switches via a dynamic gating mechanism based (...) on a temporal‐differences reward‐prediction learning mechanism. Unlike prior models of this type, the present model develops all of its internal representations via learning mechanisms as shaped by the demands of continuous periodic task switching. This advance opens up a new domain of research into the interactions between working memory task demands and the representations that develop to meet them. Results on a version of the Wisconsin card sorting task are presented for the full model and a number of comparison networks that test the importance of various model features. Furthermore, we show that a lesioned model produces perseverative errors like those seen in frontal patients. (shrink)

In neither of his two major forays into the laws of war and peace – De iure praedae or De iure belli ac pacis – did Hugo Grotius discuss the legal institutions of reprisal – whether special or general – or privateering in their own right. His profoundly novel reading of the just war doctrine in the context of his theory of natural rights, however, gave powerful legitimisation to the practices of special reprisals, as well as of privateering in times (...) of war and of peace.

The Cambridge Companion to Grotius offers a comprehensive overview of Hugo Grotius for students, teachers, and general readers, while its chapters also draw upon and contribute to recent specialised discussions of Grotius' oeuvre and its later reception. Contributors to this volume cover the width and breadth of Grotius' work and thought, ranging from his literary work, including his historical, theological and political writing, to his seminal legal interventions. While giving these various fields a separate treatment, the book also delves into (...) the underlying conceptions and outlooks that formed Grotius' intellectual map of the world as he understood it, and as he wanted it to become, giving a new political and religious context to his forays into international and domestic law.

In lieu of an abstract, here is a brief excerpt of the content:?;5. HUME AND SPINOZA It is strange that there has been so little interest in comparing two great philosophers, Hume and -Spinoza, who were both so important and influential in bringing about the decline of traditional religion. Jessop's bibliography indicates no interest in Hume and Spinoza up to the 1930 's. The Hume conferences of 1976, as far as I have been able to 2 determine, avoided the topic. (...) In one of the better new Hume volumes, Livingston and King, Hume, A Re-evaluation, 3 Spinoza is cited twice, and once incorrectly at that. On the other hand, in the massive new Spinoza volume edited by Siegfried Hessing, Speculum Spinozanun 1677-1977, Hume is mentioned four times, but only one of these has any real relevance to Hume's views vis-a-vis Spinoza's. Some discussion of Hume's comments, usually brief, occurs in the commentators. B. M. Laing, in David Hume, (London 1932), has just three short references to Spinoza. John Laird, in Hume's Philosophy of Human Nature, (London 1932) has a couple of cursory references to Spinoza, plus a bit more extended statement of Pierre Bay le" s critique of him. In H. H. Price, Hume's Theory of the External World, (Oxford 1940), there is one paragraph on Hume and Spinoza. In Norman Kemp Smith, The Philosophy of David Hume (London 1941), there are three references to Spinoza. Rachel Kydd, Reason and Conduct in Hume's Treatise (Oxford 194 6), has the greatest number of references to Spinoza. She was concerned to compare him with Hume on other matters than are dealt with in this paper, namely Spinoza's theory of reason and 9 the passions. In contrast, André Leroy, David Hume, (Paris 1953), has just one paragraph on Spinoza dealing with the immateriality of the soul; and Ernest C. Mossner, in his monumental Life of David Hume, (Austin 1954), has only one reference to Spinoza - James Beattie's denunciation of Hume, Hobbes, Malebranche, Leibniz and Spinoza. Lastly, in a fairly recent commentary by James Noxon, Spinoza is mentioned 66. three times, but not for anything in Hume's text. Noxon does point out (p. 75) that Spinoza is not mentioned in ] 2 Hume's correspondence. John H. Randall has offered an explanation for this neglect of Spinoza by Hume scholars, namely that "Hume stands for all time as the antithesis of Spinoza in his thought". In the England of Hume's day, Spinoza was little known, but still better known at the time than he was in France or England. Spinoza's Tractatus Theologico-Politicus 14 had been twice translated into English anonymously. He had been attacked by Bishop Stillingfleet, by John Evelyn, by Berkeley and several others. But Spinoza was not a major figure, except to the English Deists, and to Hume's early patron, the Chevalier Andrew Michael Ramsay. Most of the information known about Spinoza came from Pierre Bayle' s Historical and Critical Dictionary, where the article "Spinoza" is the longest in the Dictionary, about three hundred pages in length. My suspicion, or hypothesis, is that Hume first became interested in Spinoza through Ramsay, and then learned what he knew about Spinoza from Bayle' s article. When the young David Hume went to France to write his A Treatise of Human Nature in 1734, he went first to see the Chevalier Ramsay, who entertained Hume for about two weeks. Ramsay was a leading Scottish Catholic, was the teacher of Bonnie Prince Charlie, a leading Scottish revolutionary, 18 as well as the Grand Master of the Free Masons. With Ramsay's eclectic views it is not odd that he had a serious interest in Spinoza's theory, and that he was composing answers to it. Ramsay advised Hume about his own book, and Hume felt he had to show Ramsay the Treatise before he 19 brought it back to England. In the Treatise there is a not too well studied section on Spinoza, Of the immateriality of the soul 20 (T240-45). In introducing Spinoza into the discussion of 67. the immateriality of the soul, Hume follows what was common practice in his day, namely to insult Spinoza and his theory... (shrink)

Both Carnap and Quine made significant contributions to the philosophy of mathematics despite their diversedviews. Carnap endorsed the dichotomy between analytic and synthetic knowledge and classified certainmathematical questions as internal questions appealing to logic and convention. On the contrary, Quine wasopposed to the analytic-synthetic distinction and promoted a holistic view of scientific inquiry. The purpose of thispaper is to argue that in light of the recent advancement of experimental mathematics such as Monte Carlosimulations, limiting mathematical inquiry to the domain of (...) logic is unjustified. Robustness studies implemented inMonte Carlo Studies demonstrate that mathematics is on par with other experimental-based sciences. (shrink)

John Calvin claims that the foundation of Scripture is the oracles and visions revealed to the patriarchs, transmitted through countless generations by an oral tradition that faithfully preserved these oracles. The oral tradition of the patriarchs also contains practices not found in written Scripture that are applicable to the church of Calvin day.

This paper examines the investigations carried out between 1798 and 1834 to determine whether, and how, magnetism affected the rate at which marine chronometers gained or lost time. There were persistent claims that chronometers systematically altered rate between those determined on land and those at sea, and magnetism was thought by some to be the most likely cause. Others disputed any rate difference at all. The experiments carried out to determine the influence of magnetism and those carried out to determine (...) if there was a difference between land and sea rates of chronometers will be considered. The data will be re-analysed in an attempt to extract additional information to clarify the answers to these questions. The influence these experiments had on certain navigational practices will be discussed briefly. (shrink)
