Recent scholarship, focusing on the rapid decline of microscopy after the late 1680's, has shown that the limitations of microscopy and the ambivalent meaning of its findings led to a wide-spread sense of frustration with the new instrument. The present article tries to connect this fall from favor with the microscope's equally surprising but hitherto little noticed late rise to prominence. The crucial point is that when the microscope, more than a decade after the telescope, finally managed to arouse (...) the interest of natural philosophers, it did so as a corpuscularian tool, and as such it came to share the difficult fate of seventeenth-century corpuscularianism. The essay ends with the claim that the fall of microscopy was not only due to the failure of microscopy to corroborate corpuscularianism, but also to the changing definition of natural philosophy in the late seventeenth and early eighteenth centuries and to the separation of the domains of living matter from a physica whose recent mathematical framework excluded the organic world.

I. The Antiope.—The papyrus fragments of theAntiope, written in a small and crabbed hand of the third century B.C., were first published by Mahaffy in vol. 1 of the Petrie papyri in 1891, a time when the study of writing on papyrus was in its early days and there was not the abundance of other literary texts to provide practice and comparison that there is to-day. An advance in the study of the text was made by Blass in 1892, whose (...) readings were based on first-hand knowledge of the manuscript; he was followed by von Arnim, who in his text in the Supplementum Euripideum introduced several startling alterations, based on the autotypes alone and very rarely justified by the papyrus. A landmark in the history of the text was reached when Hans Schaal published his dissertation De Euripidis Antiopa; not only had he studied the papyrus closely in London, but he was able to make use of several readings of Wilamowitz. Though he left some of the major problems unattacked, perhaps too readily, his text represents a great advance on that of his predecessors, and I have found his readings in the majority of cases where he differs from Mahaffy or von Arnim confirmed by the papyrus, and consequently I have taken his text as the basis of my collation. That there was still a little more to be deciphered was suggested to me by the late Dr. Hunt, and I am indebted to him as the instigator of these notes if there is anything of value in them.

Despite the growing routinization of prenatal diagnosis, little research has examined men's roles in this reproductive arena or these technologies' possibilities for reinforcing or transforming gender roles and relations. The authors analyze male partners' participation in the amniocentesis decisions of Mexican-origin women at high risk for problems, drawing on interviews with 157 women and 120 of their male partners. The primary aim is to explore whether the normalization of prenatal testing poses a threat to women's autonomy in this decision (...) arena. The findings challenge critics of new reproductive and genetic technologies who assume that these technologies inherently represent male attempts to control women's bodies and the processes of reproduction. In contrast, the authors find many couples try to balance their desire to share equally in parenting responsibilities while maintaining the woman's ultimate control over her body and decisions associated with it.

As the rising costs of lifestyle-related diseases place increasing strain on public healthcare systems, the individual’s role in disease may be proposed as a healthcare rationing criterion. Literature thus far has largely focused on retrospective responsibility in healthcare. The concept of prospective responsibility, in the form of a lifestyle contract, warrants further investigation. The responsibilisation in healthcare debate also needs to take into account innovative developments in mobile health technology, such as wearable biometric devices and mobile apps, which may change (...) how we hold others accountable for their lifestyles. Little is known about public attitudes towards lifestyle contracts and the use of mobile health technology to hold people responsible in the context of healthcare. This paper has two components. Firstly, it details empirical findings from a survey of 81 members of the United Kingdom general public on public attitudes towards individual responsibility and rationing healthcare, prospective and retrospective responsibility, and the acceptability of lifestyle contracts in the context of mobile health technology. Secondly, we draw on the empirical findings and propose a model of prospective intention-based lifestyle contracts, which is both more aligned with public intuitions and less ethically objectionable than more traditional, retrospective models of responsibility in healthcare.

Originally published in 1913, this book charts the development, growth and legacy of the schools of the Jansenists of Port-Royal based in Paris. The Port-Royalists used many innovative teaching methods in the years before they were closed down in the mid-seventeenth century, such as their use of the vernacular and their views on the role of the teacher, and Barnard examines the place that the Port-Royalists held in the context of French education more generally to illustrate their lasting influence on (...) other schools. This book will be of value to anyone with an interest in Jansenism and the history of education. (shrink)

Background Ethically, informed consent regarding randomised controlled trials (RCTs) should be understandable to patients. The patients can then give free consent or decline to participate in a RCT. Little is known about what patients really understand in consultations about RCTs. Methods Cancer patients who were asked to participate in a randomised trial were surveyed using a semi-standardised interview developed by the authors. The interview addresses understanding, satisfaction and needs of the patients. The sample included eight patients who participated in (...) a trial and two who declined. The data were analysed on the basis of Mayring's qualitative analysis. Results Patients' understanding of informed consent was less developed than anticipated, especially concerning key elements such as randomisation, content and procedure of RCTs. Analysing the result about satisfaction of the patients, most of the patients described their consultations as hectic and without advance notice. Health limitations due to cancer played a decisive role. However, most of the patients perceived their physician to be sympathetic. Analysing the needs of patients, they ask for a clear informed consent consultation with enough time and adequate advance notice. Conclusion This study fills an important empirical research gap of what is ethically demanded in an RCT consultation and what is really understood by patients. The qualitative approach enabled us to obtain new results about cancer patients' understanding of informed consent, to clarify patients' needs and to develop new ideas to optimise the informed consent.

_Psychological Types_ is one of Jung's most important and most famous works. First published by Routledge in the early 1920s it appeared after Jung's so-called fallow period, during which he published little, and it is perhaps the first significant book to appear after his own confrontation with the unconscious. It is the book that introduced the world to the terms 'extravert' and 'introvert'. Though very much associated with the unconscious, in _Psychological Types_ Jung shows himself to be a supreme (...) theorist of the conscious. In putting forward his system of psychological types Jung provides a means for understanding ourselves and the world around us: our different patterns of behaviour, our relationships, marriage, national and international conflict, organizational functioning. Appearing in paperback for the first time this central volume from Jung's Collected Works will be essential to anyone requiring a proper understanding of Jung's psychology. (shrink)

This article is a survey of familiar ground—those passages of the Poetics of Aristotle which throw light on the treatment of legend by the tragic poets. Although sweeping generalizations are often made on the use of the traditional stories in drama, our evidence on the subject is slight and inconclusive. We have little knowledge of the form in which most of the legends were known to the Attic playwrights, for the few we find in the Iliad and Odyssey appear (...) there in very different versions from those they take on in the plays, and the fragmentary remains of epic and lyric poetry between Homer and the fifth century B.C. present us with a wide field for speculation, but few certain facts; while vase paintings and other works of art supplement only here and there the scanty information gained from literature.The comments of ancient writers on this aspect of tragedy are surprisingly few, and carry us little farther. The Poetics stands out as the one source from which we can draw any substantial account of the matter. Even Aristotle, of course, is not directly concerned with the history of drama, and deals with it only incidentally in isolated passages; and in considering these it must constantly be borne in mind that he is discussing tragedy as he knew it in the late fourth century, for the benefit of fourth-century readers. But even so, his statements are the main foundation on which our view of the dramatists' use of legend must be built. (shrink)

Background When anti-cancer treatments have been given market authorization, but are not (yet) reimbursed within a healthcare system, physicians are confronted with ethical dilemmas. Arranging access through other channels, e.g., hospital budgets or out-of-pocket payments by patients, may benefit patients, but leads to unequal access. Until now, little is known about the perspectives of physicians on access to non-reimbursed treatments. This interview study maps the experiences and moral views of Dutch oncologists and hematologists.Methods A diverse sample of oncologists and (...) hematologists (n = 22) were interviewed. Interviews were analyzed thematically using Nvivo 12 qualitative data software.Results This study reveals stark differences between physicians’ experiences and moral views on access to anti-cancer treatments that are not (yet) reimbursed: some physicians try to arrange other ways of access and some physicians do not. Some physicians inform patients about anti-cancer treatments that are not yet reimbursed, while others wait for reimbursement. Some physicians have principled moral objections to out-of-pocket payment, while others do not.Conclusion Oncologists and hematologists in the Netherlands differ greatly in their perspectives on access to expensive anti-cancer treatments that are not (yet) reimbursed. As a result, they may act differently when confronted with dilemmas in the consultation room. Physicians working in different healthcare systems may face similar dilemmas. (shrink)

The discussion of the construction with usus est is conventionally bound up with that of opus est, and comparatively little attention has been given to the problem presented by the use of the ablative case with the former phrase. The tendency to pass lightly over this matter is due doubtless to the manifest etymological connexion between usus and utor, which leads to the assumption that the verbal noun would naturally follow the syntax of the verb.

With the rise of the knowledge economy, the knowledge content of goods and services is going up just as their material content is declining. Economic value is increasingly seen to reside in the former - that is, in intangible assets - rather than in the latter. Yet we keep wanting to turn knowledge back into something tangible, something with definite boundaries which can be measured, manipulated, appropriated, and traded. In short, we want to reify knowledge. Scholars have been debating the (...) nature of knowledge since the time of Plato. Many new insights have been gained from these debates, but little theoretical consensus has been achieved. Through six thematically linked chapters, the book articulates the theoretical approach to the production and distribution of knowledge that underpins Max Boisot's conceptual framework, the Information Space or I-Space. In this way the book looks to provide theoretical and practical underpinnings to Boisot's book Knowledge Assets.Following an introductory chapter, how knowledge relates to data and information is first examined in chapter 1, and how different economic actors - entrepreneurs, managers, etc - use knowledge as a basis for action is explored in chapter 2. Chapter 3 looks at how the heterogeneity of economic actors arises naturally from their respective data processing strategies in spite of any similarities in the data that they might share. Chapter 4 argues, contra much transaction-based economics, that an organizational order must have preceded a market order, something that should be reflected in any knowledge-based theory of the firm. Chapter 5 discusses the cultural and institutional significance of different kinds of knowledge flows. Finally, chapter 6 presents an agent-based simulation model, SimISpace, that illustrates how the I-Space might be applied to concrete problems such those of intellectual property rights. A concluding chapter proposes a research agenda based on the theorizing developed in the book.The approach the book sets out is used by a whole range of organizations to issues of knowledge management, policy, economics, and organizational and cultural change.

Crowdfunded microfinance provides financial resources to impoverished entrepreneurs across the globe based on online appeals describing the entrepreneur’s values and venture potential and is considered a key player in the ethical finance movement. Despite knowledge that the content of the appeals impacts funding success, little is known regarding the role of religious expression, which is common and consequential in socially-oriented contexts. We leverage role congruity theory to address a theoretical tension concerning the effects of religious expression on crowdfunded microfinance (...) funding outcomes. Religious expression is associated with perceptions of trustworthiness, rule-following, and ethicality—qualities that would suggest an entrepreneur would likely avoid opportunist behavior and repay the loan. However, appeals to a higher power may be incongruent with the role of an entrepreneur to the extent that such expression communicates a lack of proactiveness and self-reliance. We use a two-study design to help resolve this tension. Our field study incorporating 253,130 loans from Kiva reveals that religious expression negatively influences funding, particularly for women. Our experiment using 1,795 individual loan assessments shows that the negative influence of religious expression is attenuated when individual lenders exhibit higher levels of religiosity. Post hoc analysis suggests campaigns can mitigate the negative impact of religious expression by being careful to also include aspects highlighting an entrepreneurial orientation. Overall, our work extends prior research suggesting that language tied to ethical or virtuous behaviors is generally not rewarded by lenders as using such language may make the applicant appear inconsistent with role of a stereotypical entrepreneur.

In 1958, economist A. W. Phillips published an article describing what he observed to be the inverse relationship between inflation and unemployment; subsequently, the "Phillips curve" became a central concept in macroeconomic analysis and policymaking. But today's Phillips curve is not the same as the original one from fifty years ago; the economy, our understanding of price setting behavior, the determinants of inflation, and the role of monetary policy have evolved significantly since then. In this book, some of the top (...) economists working today reexamine the theoretical and empirical validity of the Phillips curve in its more recent specifications. The contributors consider such questions as what economists have learned about price and wage setting and inflation expectations that would improve the way we use and formulate the Phillips curve, what the Phillips curve approach can teach us about inflation dynamics, and how these lessons can be applied to improving the conduct of monetary policy.

Background: Discussions about medical errors facilitate professional learning for physicians and may provide emotional support after an error, but little is known about physicians’ attitudes and practices regarding error discussions with colleagues.Methods: Survey of faculty and resident physicians in generalist specialties in Midwest, Mid-Atlantic and Northeast regions of the US to investigate attitudes and practices regarding error discussions, likelihood of discussing hypothetical errors, experience role-modelling error discussions and demographic variables.Results: Responses were received from 338 participants . In all, 73% (...) of respondents indicated they usually discuss their mistakes with colleagues, 70% believed discussing mistakes strengthens professional relationships and 89% knew at least one colleague who would be a supportive listener. Motivations for error discussions included wanting to learn whether a colleague would have made the same decision , wanting colleagues to learn from the mistake and wanting to receive support . Given hypothetical scenarios, most respondents indicated they would likely discuss an error resulting in no harm , minor harm or major harm . Fifty-seven percent of physicians had tried to serve as a role model by discussing an error and role-modelling was more likely among those who had previously observed an error discussion .Conclusions: Most generalist physicians in teaching hospitals report that they usually discuss their errors with colleagues, and more than half have tried to role-model discussions. However, a significant number of these physicians report that they do not usually discuss their errors and some do not know colleagues who would be supportive listeners. (shrink)

This is a study of what Spinoza intended to be the refutation of orthodox Judaism, and indeed, of all religious orthodoxy. The recovery of that refutation, as Strauss illustrates in his preface to this translation, is needed by theology because the progressive liberalization of religion has now reached the point where theology is hardly able to distinguish itself from sundry civil moralities. Owing to this beginning, both in its plan and execution this study has little in common with historical (...) studies of the origin of religious liberalism. Part I distinguishes the classical or Epicurean critique of religion, which did not entail enlightenment, from the modern critique, whose origin Strauss finds in Hobbes. Part II examines Spinoza's critique of orthodoxy, the critique of Calvin, the teaching on the relation between religion and politics, and the concept of Bible criticism. Since Strauss' guiding concern is to discover whether the critique of orthodoxy can be met from the grounds of orthodoxy, he takes great care to specify precisely the assumptions of each argument and the belief against which it is directed. When completed, this effort becomes the articulation of the conflict between reason and revelation. That conflict is shown as it is understood by each side, and Strauss assesses the vulnerability of each to the other.—H. C. (shrink)

This chapter discusses four packages, including Ludovician, Aristotelian, Fortibracchian, and Quietist. There are two quite coherent packages of answers to the some issues: a neo‐Humeist or Ludovician package, and a neo‐Aristotelian package. Ludovicians put little weight on common sense beliefs, especially when they are embedded in ethical and legal practices, and they do not rely heavily on the "manifest image of the world". Aristotelians rely more heavily on the semantic intuition about what could possibly be the truthmakers for familiar (...) kinds of claims, including those involving tense and modality. This chapter lists the Aristotelian package as including Meinongianism, ontological vagueness, and Tensism on the passage of time. Fortibracchians are very similar in methodology to Ludovicains. In practice, Fortibracchians give more weight to a kind of naive realism with respect to scientific theory than do Ludovicians. (shrink)

Hypnotic responding might be due to attenuated frontal lobe functioning after the hypnotic induction. Little is known about whether personality traits linked with frontal functioning are associated with responsiveness to hypnotic suggestions. We assessed whether hypnotic suggestibility is related to the traits of self-control and impulsivity in 154 participants who completed the Brief Self-Control Scale, the Self-Regulation Scale, the Barratt Impulsiveness Scale , and the Harvard Group Scale of Hypnotic Susceptibility . BIS-11 non-planning impulsivity correlated positively with HGSHS:A . (...) Furthermore, in the best model emerging from a stepwise multiple regression, both non-planning impulsivity and self-control positively predicted hypnotic suggestibility, and there was an interaction of BIS-11 motor impulsivity with gender. For men only, motor impulsivity tended to predict hypnotic suggestibility. Hypnotic suggestibility is associated with personality traits linked with frontal functioning, and hypnotic responding in men and women might differ. (shrink)

Endothelial cells line the inside of all blood vessels, forming a structurally and functionally heterogenous population of cells. Their complexity and diversity has long been recognized, yet very little is known about the molecules and regulatory mechanisms that mediate the heterogeneity of different endothelial cell populations. The constitutive organ‐ and microenvironment‐specific phenotype of endothelial cells controls internal body compartmentation, regulating the trafficking of circulating cells to distinct vascular beds. In contrast, surface molecules associated with the activated cytokine‐inducible endothelial phenotype (...) play a critical role in pathological conditions including inflammation, tumor angiogenesis, and wound healing. Differentiation of the endothelial cell phenotypes appears to follow similar mechanisms to the differentiation of hematopoietic cells, with the exception that endothelial cells maintain transdifferentiating competence. The present review offers a scheme of endothelial cell differentially expressed endothelial cell molecules as targets for directed therapeutic intervention. (shrink)

Fossil fuel divestment movements have gained momentum since 2011, aimed at ending fossil fuel use and a move toward a cleaner, affordable, and sustainable energy system, for business and society. The present study investigates the direct impact of fossil fuel divestment announcements on stock prices of firms listed on the United States' stock exchanges. Using an event study and guided by the United Nation's sustainable development goals (SDGs), we test the effects of 116 divestments announcements between 2014 and 2019 on (...) 51 publicly traded fossil fuel companies. Our results suggest that there is a negative effect of these announcements on fossil fuel firm stock prices. Also, we find that the type of fossil fuel firm (coal or oil and gas), the type of divestment (partial, coal only, or full), the timing of the announcement, and the size of the divesting investor have some explanatory power in relation to the (cumulative) abnormal returns following the divestment announcements. While the negative impact on stock prices is not surprising, the reaction from the divested firms after such large divestitures is not consistent with what may be expected, given past reactions to divestitures seeking to achieve different social goals. Given the SDGs, it seems clear why investors are divesting themselves from fossil fuel firms, but why has the reaction to the 116 divestments led to very little change in the way these publicly traded fossil fuel firms do business given their direct and growing impacts on society? We conclude the study with some suggestions for future research. (shrink)

Patients fit with cochlear implants commonly indicate at the time of device fitting and for some time after, that the speech signal sounds abnormal. A high pitch or timbre is one component of the abnormal percept. In this project, our aim was to determine whether a number of years of CI use reduced perceived upshifts in frequency spectrum and/or voice fundamental frequency. The participants were five individuals who were deaf in one ear and who had normal hearing in the other (...) ear. The deafened ears had been implanted with a 18.5 mm electrode array which resulted in signal input frequencies being directed to locations in the spiral ganglion that were between one and two octaves higher than the input frequencies. The patients judged the similarity of a clean signal presented to their implanted ear and candidate, implant-like, signals presented to their normal-hearing ear. Matches to implant sound quality were obtained, on average, at 8 months after device activation and at 35 months after activation. At Time 1, the matches to CI sound quality were characterized, most generally, by upshifts in the frequency spectrum and in voice pitch. At Time 2, for four of the five patients, frequency spectrum values remained elevated. For all five patients F0 values remained elevated. Overall, the data offer little support for the proposition that, for patients fit with shorter electrode arrays, cortical plasticity nudges the cortical representation of the CI voice toward more normal, or less upshifted, frequency values between 8 and 35 months after device activation. Cortical plasticity may be limited when there are large differences between frequencies in the input signal and the locations in the SG stimulated by those frequencies. (shrink)

Directional deep brain stimulation contacts provide greater spatial flexibility for therapy than traditional ring-shaped electrodes, but little is known about longitudinal changes of impedance and orientation. We measured monopolar and bipolar impedance of DBS contacts in 31 patients who underwent unilateral subthalamic nucleus deep brain stimulation as part of a randomized study. At different follow-up visits, patients were assigned new stimulation configurations and impedance was measured. Additionally, we measured the orientation of the directional lead during surgery, immediately after surgery, (...) and 1 year later. Here we contrast impedances in directional versus ring contacts with respect to local anatomy, active stimulation contact, and over time. Directional contacts display larger impedances than ring contacts. Impedances generally increase slightly over the first year of therapy, save for a transient decrease immediately post-surgery under general anesthesia during pulse generator placement. Local impedances decrease at active stimulation sites, and contacts in closest proximity to internal capsule display higher impedances than other anatomic sites. DBS leads rotate slightly in the immediate postoperative period but otherwise remain stable over the following year. These data provide useful information for setting clinical stimulation parameters over time. (shrink)

Looking at current scholarship and opinion in American philosophy, one can easily conclude that there has been much more work done on studying the history of pragmatist philosophy than there has been on what pragmatist philosophy can give to the study of history.

Bücheler assigns this epitaph to the Caesarian epoch: and it is clearly not of later date. The fifth line is corrupt. Bücheler suggests tentatively the insertion of the word dilecto after Cadmo. That will indeed give us a verse of six feet. But we shall not be much the happier. We shall still have to believe that a member of the gens Heluia married, circa 100&50 B.C, a husband of the name of Cadmus Scrateius.

Although there is good experimental evidence for the Aharonov–Bohm phase shift occurring when a solenoid is placed between the beams forming a double-slit electron interference pattern, there has been very little analysis of the relevant classical electromagnetic forces. These forces between a point charge and a solenoid involve subtle relativistic effects of order v 2 /c 2 analogous to those discussed by Coleman and Van Vleck in their treatment of the Shockley–James paradox. In this article we show that a (...) treatment exactly analogous to that given by Coleman and Van Vleck predicts classical electromagnetic forces which provide the basis for the Aharonov–Bohm phase shift. The magnetic force on the solenoid due to the passing charge leads to a displacement of the solenoid center of energy which must be balanced by the displacement of the passing charge. This classical displacement of the passing charge is exactly what is required to account for the Aharonov–Bohm phase shift. Also, we discuss a magnetic moment model which appears frequently in the literature and note that although the model provides conservation of linear momentum, it does not satisfy the general requirements for relativistic theories. We give an example suggesting that the new equation of motion for a magnetic moment proposed by Aharonov, Pearle, and Vaidman based upon the hidden momentum of the magnetic moment is completely inappropriate. Finally, we emphasize that the Aharonov–Casher phase shift is also explained by classical electromagnetic forces exactly parallel to those explaining the Aharonov–Bohm phase shift. (shrink)

In his note [5] Hausner states a simple combinatorial principle, namely: $$(H)\left\{ {\begin{array}{*{20}c} {if f is a function a non - empty finite set \sigma into itself, p a} \\ {prime, f^p = i_\sigma and \sigma _0 the set of fixed points of f, then } \\ {\left| \sigma \right| \equiv \left| {\sigma _0 } \right|(mod p).} \\\end{array}} \right.$$ .He then shows how this principle can be used to prove:Fermat's little theorem,Cauchy's theorem for finite groups,Lucas' theorem for binomial numbers.Letε=(0,1, (...) ...),ℱ 1−1 the family of all one-to-one functions from a subset ofε intoε andℳ 1−1 the family of all p.r. (i.e., partial recursive) one-to-one functions from a subset ofε intoε. A subsetα of ε is finite, ifα is not equivalent to a proper subset under a function inℱ 1−1. The setα is calledisolated, if it is not equivalent to a proper subset under a function inℳ 1−1. An isolated set can also be defined as a subset ofε which has no infinite r.e. (i.e., recursively enumerable) subset. While every finite set is isolated, there are $c = 2^{\aleph _0 }$ infinite sets which are isolated; these sets are calledimmune. It is the purpose of this paper to generalize (H) to a principle (H*) for isolated sets and to show how (H*) can be used to prove generalizations of Fermat's little theorem and Cauchy's theorem for finite groups. We have been unable to generalize Lucas' theorem in a similar manner. (shrink)

It is traditionally believed that cerebral activation (the presence of low voltage fast electrical activity in the neocortex and rhythmical slow activity in the hippocampus) is correlated with arousal, while deactivation (the presence of large amplitude irregular slow waves or spindles in both the neocortex and the hippocampus) is correlated with sleep or coma. However, since there are many exceptions, these generalizations have only limited validity. Activated patterns occur in normal sleep (active or paradoxical sleep) and during states of anesthesia (...) and coma. Deactivated patterns occur, at times, during normal waking, or during behavior in awake animals treated with atropinic drugs. Also, the fact that patterns characteristic of sleep, arousal, and waking behavior continue in decorticate animals indicates that reticulo-cortical mechanisms are not essential for these aspects of behavior.

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)

It is a pleasure for me to give this opening address to the Royal Institute of Philosophy Conference on ‘Explanation’ for two reasons. The first is that it is succeeded by exciting symposia and other papers concerned with various special aspects of the topic of explanation. The second is that the conference is being held in my old alma mater, the University of Glasgow, where I did my first degree. Especially due to C. A. Campbell and George Brown there was (...) in the Logic Department a big emphasis on absolute idealism, especially F. H. Bradley. My inclinations were to oppose this line of thought and to espouse the empiricism and realism of Russell, Broad and the like. Empiricism was represented in the department by D. R. Cousin, a modest man who published relatively little, but who was of quite extraordinary philosophical acumen and lucidity, and by Miss M. J. Levett, whose translation of Plato's Theaetetus formed an important part of the philosophy syllabus. (shrink)

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.
