This article traces the life of Russian chemist Dmitri Mendeleev from childhood in Siberia, through education and training to become the first formulator of the Periodic Table, the logo of chemistry. His unique contribution is described and analysed; what factors helped him be the first formulator? What did he do after making his most famous discovery? In addition the article peeps into his personal life, his dealings with his family and the authorities. Finally we look at honours he received in (...) later life. (shrink)
It is shown, assuming the linear case of Schinzel's Hypothesis, that the first-order theory of the structure $\langle \omega; +, P\rangle$ , where P is the set of primes, is undecidable and, in fact, that multiplication of natural numbers is first-order definable in this structure. In the other direction, it is shown, from the same hypothesis, that the monadic second-order theory of $\langle\omega; S, P\rangle$ is decidable, where S is the successor function. The latter result is proved using a general (...) result of A. L. Semenov on decidability of monadic theories, and a proof of Semenov's result is presented. (shrink)
A possible worlds treatment of the normal alethic modalities was, after classical model theory, logic’s most significant semantic achievement in the century just past.[1] Kripke’s groundbreaking paper appeared in 1959 and, in the scant few succeeding years, its principal analytical tool, possible worlds, was adapted to serve a range of quite different-seeming purposes – from nonnormal logics,[2] to epistemic and doxastic logics[3], deontic[4] and temporal logics[5] and, not much later, the logic of counterfactual conditionals.[6] In short order, possible worlds acquired (...) a twofold reputation which has steadily enlarged to the present day. They were celebrated for both their mathematical power and their sheer versatility. This sets the stage for what I want to do here. I wish to explore the extent to which the supposed versatility of a possible worlds semantics is justified. In so doing, I shall confine my attention to its role in (1) logics of counterfactual conditionals, and (2) logics of belief. The question I pose is, why and on what grounds should we think that the device of possible worlds turns the semantic trick for these logics? My answer is that they do not turn the trick for them. Whereupon a further question presses for attention. If possible worlds semantics don’t work there, why does virtually everyone think that they do? Answering this second question is risky. Who am I to say why virtually everyone thinks that the possible worlds approach is more successful than I do? Who has vouchsafed me these powers? I shall try to mitigate the riskiness of my answer by contextualizing the evaluation of this approach in the following ways. First, the triumph of possible worlds occurred in the midst of a powerful general trend in logical theory, especially, in the past 60 years. In that period, logical theory became aggressively and widely pluralistic. Second, the versatility – the sheer ubiquity – of possible worlds as a tool of semantic and philosophical analysis, gives to possible worlds a kind of hegemonic standing.. (shrink)
An account of analogical characterization is developed in which the following things are claimed.(1) Analogical predications are irreflexive, asymmetrical, atransitive and non-inversive. (2) Analogies A and B share role-similarity descriptions sufficiently abstract to overcome the differences between A and B. Analogies pivot on the point of limited similarity and substantial, even radical, difference. (3) The semantical theory for sentences making analogical attributions requires a distinction between (sentential) meaning as truth conditions and (sentential) meaning as a functional compound of the meanings (...) of contained lexical items. Analogical sentences possess both kinds of meaning. They are true via their truth conditions and would be false via their lexical meanings. The distinctive feature of the lexical meaning of analogical sentences is the tightness of constraints on closure. The implications of analogical sentences, given their lexical meanings, though there, aren't drawn. It is in this sense that analogies are made and not found. (shrink)

What if a tree told a joke in the woods and there was no one there to hear it? Occasionally I watch The Ellen DeGeneres Show. I have appreciated Ellen as a comedian since she first came on the public scene, and one part of her talk show that I enjoy is the dancing in the opening segment, where Ellen dances to music played by a DJ, and she goes up into the audience and the overwhelmingly female audience dances (...) with her. I like to dance and I enjoy watching other people dance, but the Ellen dance segment also holds a special fascination for me, as there is a style of dancing I have observed over the last twenty-five years or so, a style that might as well be called “lesbian,” and which, if you don’t ..

Abstract Objectives To conduct an independent evaluation of the first phase of the Health Foundation’s Safer Patients Initiative (SPI), and to identify the net additional effect of SPI and any differences in changes in participating and non-participating NHS hospitals. Design Mixed method evaluation involving five substudies, before and after design. Setting NHS hospitals in the United Kingdom. Participants Four hospitals (one in each country in the UK) participating in the first phase of the SPI (SPI1); 18 control hospitals. Intervention The (...) SPI1 was a compound (multi-component) organisational intervention delivered over 18 months that focused on improving the reliability of specific frontline care processes in designated clinical specialties and promoting organisational and cultural change. Results Senior staff members were knowledgeable and enthusiastic about SPI1. There was a small (0.08 points on a 5 point scale) but significant (P<0.01) effect in favour of the SPI1 hospitals in one of 11 dimensions of the staff questionnaire (organisational climate). Qualitative evidence showed only modest penetration of SPI1 at medical ward level. Although SPI1 was designed to engage staff from the bottom up, it did not usually feel like this to those working on the wards, and questions about legitimacy of some aspects of SPI1 were raised. Of the five components to identify patients at risk of deterioration—monitoring of vital signs (14 items); routine tests (three items); evidence based standards specific to certain diseases (three items); prescribing errors (multiple items from the British National Formulary); and medical history taking (11 items)—there was little net difference between control and SPI1 hospitals, except in relation to quality of monitoring of acute medical patients, which improved on average over time across all hospitals. Recording of respiratory rate increased to a greater degree in SPI1 than in control hospitals; in the second six hours after admission recording increased from 40% (93) to 69% (165) in control hospitals and from 37% (141) to 78% (296) in SPI1 hospitals (odds ratio for “difference in difference” 2.1, 99% confidence interval 1.0 to 4.3; P=0.008). Use of a formal scoring system for patients with pneumonia also increased over time (from 2% (102) to 23% (111) in control hospitals and from 2% (170) to 9% (189) in SPI1 hospitals), which favoured controls and was not significant (0.3, 0.02 to 3.4; P=0.173). There were no improvements in the proportion of prescription errors and no effects that could be attributed to SPI1 in non-targeted generic areas (such as enhanced safety culture). On some measures, the lack of effect could be because compliance was already high at baseline (such as use of steroids in over 85% of cases where indicated), but even when there was more room for improvement (such as in quality of medical history taking), there was no significant additional net effect of SPI1. There were no changes over time or between control and SPI1 hospitals in errors or rates of adverse events in patients in medical wards. Mortality increased from 11% (27) to 16% (39) among controls and decreased from 17% (63) to 13% (49) among SPI1 hospitals, but the risk adjusted difference was not significant (0.5, 0.2 to 1.4; P=0.085). Poor care was a contributing factor in four of the 178 deaths identified by review of case notes. The survey of patients showed no significant differences apart from an increase in perception of cleanliness in favour of SPI1 hospitals. Conclusions The introduction of SPI1 was associated with improvements in one of the types of clinical process studied (monitoring of vital signs) and one measure of staff perceptions of organisational climate. There was no additional effect of SPI1 on other targeted issues nor on other measures of generic organisational strengthening. (shrink)
On February 28, 2002, John Dominic Crossan gave a very well-organized and entertaining presentation for the Annual Mary Olive Woods Lecture and was well received by the large audience. His talk should spark continued interest in who is likely the most influential person ever to walk the earth. He condensed three lectures into one as he spoke of the materials, methods, and results of his historical research into the life of Jesus. The materials mentioned were the canonical Gospels of (...) Matthew, Mark, Luke and John. (Although throughout his research, Crossan relies very heavily on other texts such as the Gospel of Peter and the Gospel of Thomas, he did not mention these as material resources; see related comments below.) The bulk of his talk focused on the methods, in which he described an idealized version of what an anthropologist, an historian, and an archeologist would have to say about the early First Century Palestine, especially Galilee, if they knew nothing of the four gospels. The results are the ideas that Jesus taught primarily about the kingdom of God and used that as a basis for nonviolent resistance to the Roman Empire. The primary ministry of the historical Jesus is that of a social reformer, with political overtones. Pilate saw the threat that Jesus posed to the authority of the Romans, and had him executed because of that threat. Jesus brought “sociosomatic” healing to individuals, and encouraged his companions (not disciples) to do likewise. For an idea of what Crossan has in mind when he speaks of sociosomatic healing, think of the maturation of the main character in Good Will Hunting. With humor and a lively presentation, Crossan provided much useful and interesting information in his lecture and the discussion that followed. (shrink)
Both academic thinking about monetary economics and the practice of monetary policy have changed dramatically since 1971?3, when the rational expectations revolution was beginning and the Bretton Woods system was crumbling. The present paper considers whether the various changes that have taken place were influenced primarily by economic theory or by empirical evidence - or by a combination of the two. Monetary economics, like macroeconomics more generally, passed through the rational expectations period into one dominated by real business cycle (...) (RBC) analysis, which denies monetary policy any significant role in the generation or the dampening of cyclical fluctuations in crucial real variables. Recently, however, the analysis of monetary policy by both academic and central bank economists has been increasingly conducted in small quantitative structural models that combine the optimizing aspect of RBC analysis with various assumptions implying real effects of monetary policy actions due to slow adjustment of nominal prices. These models therefore attempt to combine rather strict theoretical discipline with features that permit an enhanced degree of empirical veracity. It is apparent, accordingly, that both theoretical and empirical analysis have been essential in bringing about alterations in monetary policy analysis between 1971?3 and 1998. (shrink)
According to Allen Wood’s “procedural principle” we should believe only that which can be justified by evidence, and nothing more. He argues that holding beliefs which are not justified by evidence diminishes our self-respect and corrupts us, both individually and collectively. Wood’s normative and descriptive views as regards belief are of a piece with the received view which holds that beliefs aim at the truth. This view I refer to as the Truth-Tracking View (TTV). I first present a modest version (...) of TTV, one which is sensitive to standard criticisms and one which is fully consistent with the procedural principle. I then raise some doubts about TTV by considering both anecdotal cases and empirical studies. These studies suggest that certain types of belief are designed to aim away from truth, in limited, carefully calibrated ways. Moreover, it seems to be the case that selectively aiming away from the truth is important for human well-being and performance. Beliefs that are designed to aim away I dub “Tertullian” beliefs (t-beliefs). I then limn the distinguishing characteristics of t-belief and proceed to evaluate the procedural principle in light of the evidence which suggests that t-belief plays an important role in our cognitive economy. Next I argue that t-beliefs might be essential to the maintenance of self-respect and that they do not corrupt in the way that Wood claims. Finally, I argue that the fate of Wood’s procedural principle will be determined by the results of further empirical research— sociological, psychological, and neuroscientific. (shrink)
Objects have dispositions. As Nelson Goodman put it, “a thing is full of threats and promises” (Goodman 1954, p. 40). But sometimes those threats go unfulfilled, and the promises unkept. Sometimes the dispositions of objects fail to manifest themselves, even when their conditions of manifestation obtain. Pieces of wood, disposed to burn when heated, do not burn when heated in a vacuum chamber. And pastries, disposed to go bad when left lying around too long, won’t do so if coated with (...) lacquer and put on display in a baker’s window. Any account of what a disposition is, or of what it takes for an object to have a disposition, should be compatible with these commonplace observations. To date, I believe, no adequate account of dispositions has been given, and the aim of this paper is to defend one. (shrink)
Great knowledge, skill, and judgment have gone into Allen Wood’s extraction from Kant’s texts, and partial defence, of a certain theory of freedom (see preceding essay). I shall later mention one respect in which I am not sure he has got Kant right, but otherwise the interpretation is flawless. I shall argue, however, that although it is worthwhile to identify Kant’s theory of freedom as Wood has helped us to do, the theory itself is worthless. I shall not list the (...) reasons that Wood anticipates being brought against the theory. I do have those too, being unconvinced that the concepts of noumenon and of timeless agency are really intelligible. When Kant says of a noumenon that “nothing happens in it” and yet that it “of itself begins its effects in the sensible world” (B 569), he implies that there is a making-begin which is not a happening; and I cannot understand that as anything but a contradiction. Kant himself has trouble relating timeless choices to the temporal world. On the one hand, “at the point in time when I act, I am never free” (KPV 94g 98e); on the other, “In the moment when he utters the lie, the guilt is entirely his” (B 585). Never mind. For present purpose I concede noumena, timeless agency, non-Humean causation - the lot. With all of that granted, the theory is still worthless. According to the theory, a free choice by my intelligible character causes me to have empirical character E. How can this be so, if there is also a deterministic causal explanation for my possession of E? How can a free choice cause this part of the natural causal chain without breaking the chain? Wood answers on Kant’s behalf that my intelligible choice causes not only my possession of E but also a complete natural causal history for my possession of E. Kant didn’t ever actually say this but Wood thinks that Kant’s theory “must” be construed in this way. I’m not sure that it must, but in the meantime I shall assume that it is. One significant fact about my character E is that I have beliefs about the Holocaust.. (shrink)
Three clusters of philosophically significant issues arise from Frege's discussions of definitions. First, Frege criticizes the definitions of mathematicians of his day, especially those of Weierstrass and Hilbert. Second, central to Frege's philosophical discussion and technical execution of logicism is the so-called Hume's Principle, considered in The Foundations of Arithmetic . Some varieties of neo-Fregean logicism are based on taking this principle as a contextual definition of the operator 'the number of …', and criticisms of such neo-Fregean programs sometimes appeal (...) to Frege's objections to contextual definitions in later writings. Finally, a critical question about the definitions on which Frege's proofs of the laws of arithmetic depend is whether the logical structures of the definientia reflect our pre-Fregean understanding of arithmetical terms. It seems that unless they do, it is unclear how Frege's proofs demonstrate the analyticity of the arithmetic in use before logicism. Yet, especially in late writings, Frege characterizes the definitions as arbitrary stipulations of the senses or references of expressions unrelated to pre-definitional understanding. One or more of these topics may be studied in a survey course in the philosophy of mathematics or a course on Frege's philosophy. The latter two topics are obviously central in a seminar in the philosophy of mathematics in general or more specialized seminars on logicism, or on mathematical definitions and concept formation. Author Recommends: 1. Kant, Immanuel. Critique of Pure Reason . Trans. P. Guyer and A. Wood. Cambridge: Cambridge University Press, 1999 [1781, 1787], A7-10/B11-14, A151/B190. In the first Critique , Kant appears to give four distinct accounts of analytic judgments. The initial famous account explains analyticity in terms of the predicate-concept belonging to the subject-concept (A6–7/B11). In this passage, we also find an account of establishing analytic judgments on the basis of conceptual containments and the principle of non-contradiction. (The other accounts are in terms of 'identity' (A7/B1l), in terms of the explicative–ampliative contrast (A7/B11), and by reference to the notion of 'cognizability in accordance with the principle of contradiction' (A151/B190).) 2. Frege, Gottlob. The Foundations of Arithmetic . Trans. J. L. Austin. 2nd ed. Evanston, IL: Northwestern University Press, 1980 [1884], especially sections 1–4, 87–91. Frege here criticizes and reformulates Kant's account of analyticity. Central to Frege's account is the provability of an analytic statement on the basis of (Frege's) logic and definitions that express analyses of (mathematical, especially arithmetical) concepts. 3. Frege, Gottlob. Review of E. G. Husserl. 'Philosophie der Arithmetik I [1894],' in Frege, Collected Papers . Ed. B. McGuinness. Trans. M. Black et al. Oxford: Blackwell, 1984. 195–209. In this review, Frege responds to Husserl's charge that Frege's definitions fail to capture our intuitive pre-analytic arithmetical concepts by claiming that the adequacy of mathematical definitions is measured, not by their expressing the same senses, but merely by their having the same references, as pre-definitional vocabulary. It follows not only that Husserl's criticism is unfounded, but also that there can be alternative, equally legitimate, definitions of mathematical terms. 4. Frege, 'Logic in Mathematics,' in Frege, Posthumous Writings . Trans. P. Long and R. White. Oxford: Blackwell, 1979 [1914]. 203–50. These are a set of lecture notes including, among other things, an account of proper definitions as mere abbreviation of complex signs by simple ones, in contrast to definitions which purport to express the analyses of existing concepts. Frege here claims that if there is any doubt whether a definition purporting to express an analysis succeeds in capturing the senses of the pre-definitional expressions, then the definition fails as an analysis, and should be regarded as the introduction of an entirely new expression abbreviating the definiens . 5. Picardi, Eva. 'Frege on Definition and Logical Proof,' Temi e Prospettive della Logica e della Filosofia della Scienza Contemporanee . i vol. Eds. C. Cellucci and G. Sambin. Bologna: Cooperativa Libraria Universitaria Editrice Bologna, 1988. 227–30. Picardi sets out forcefully the view that unless Frege's definitions capture the meanings of existing arithmetical terms, his logicism cannot have the epistemological significance he takes it to have. 6. Dummett, Michael. 'Frege and the Paradox of Analysis,' in Dummett, Frege and other Philosophers . Oxford: Oxford University Press, 1991. 17–52. Dummett agrees with Picardi's view and analyzes the philosophical pressures that led Frege to the account of definition in 'Logic in Mathematics.' Especially significant is Dummett's claim of the centrality of the transparency of sense – that if one grasps the senses of any two expressions, one must know whether they have the same sense – in Frege's account. 7. Benacerraf, Paul. 'Frege: The Last Logicist,' Midwest Studies in Philosophy . vol. 6. Eds. P. French, T. Uehling, and H. Wettstein. Minneapolis: University of Minnesota Press, 1981. 17–35. Frege's aims, on Benacerraf's reading, are primarily mathematical. Frege was interested in traditional philosophical issues such as the analyticity of arithmetic only to the extent that they can be exploited for the mathematical goal of proving previously unproven arithmetical statements. Hence, Frege never had any serious interest in or need for showing that his definitions of arithmetical terms reflect existing arithmetical conceptions. 8. Weiner, Joan. 'The Philosopher Behind the Last Logicist,' in Frege: Tradition and Influence . Ed. C. Wright. Oxford: Blackwell, 1984. 57–79. Weiner argues that on Frege's view, prior to his definitions of arithmetical terms the references of such expressions are in fact not known by those who use arithmetical vocabulary. Thus, in Foundations , Frege operated with a 'hidden agenda' (263) namely, replacing existing arithmetic with a new science based on stipulative definitions that assign new senses to key arithmetical terms. 9. Tappenden, Jamie. 'Extending Knowledge and 'Fruitful Concepts': Fregean Themes in the Foundations of Mathematics.' Noûs 29 (1995): 427–67. Tappenden argues that Frege takes his crucial innovation over previous practices and accounts of mathematical concept formation to be the role of quantificational structure made possible by his logical discoveries. 10.

To what extent is Frege's account of analyticity in Foundations a rejection, and to what extent an updating, of Kant's view of analyticity? 2. According to Picardi it 'would be incomprehensible' how Frege's proofs tells us anything about the arithmetic we already have unless his 'definitions [are] somehow responsible to the meaning of [arithmetical] sentences as these are understood' (228). Why does she hold this? Why does Dummett agree with her? Do you think Frege's logicism needs to address this worry? 3. What are the major differences and continuities in Frege's discussions of definition in mathematics in Foundations , the review of Husserl and 'Logic in Mathematics'? 4. Frege writes that definitions must prove their worth by being fruitful. He also says that nothing can be proven using a proper definition that cannot be proven without it. Are these claims consistent? Why or why not? 5. Weiner held that in Foundations Frege had 'hidden agenda.' What, according to her, is this agenda? How does this fit with Frege's later views of definition? 6. What are Frege's main complaints about Weierstrass's definitions in 'Logic in Mathematics'? Are these criticisms consistent with Frege's account of 'definition proper' in the same text?

Europeans seeking to understand tribal arts face obvious problems of comprehending the histories, values, and ideas of vastly remote cultures. In this respect the issues faced in understanding tribal art (or folk art, primitive art, traditional art, third or fourth-world art — none of these designations is ideal) are not much different from those encountered in trying to comprehend the distant art of “our own” culture, for instance, the art of medieval Europe. But in the case of tribal or so-called (...) primitive art, there are special complications. First, objects of tribal art are sometimes so strange to us that we cannot tell immediately whether they are intended to be works of art (or some local analogue of what we would call art) at all.1An African head-rest I once came across had an odd, extravagant extrusion which made the whole piece reminiscent of Arp. It seemed to my baffled, ignorant eyes to be much more than a mere head-rest, but I couldn’t tell what more it was supposed to be. Maybe that extension on the side of the object had some purely utilitarian function, acting as a handle, or perhaps it was a natural part of the original block of wood, left there merely because it looked nice to the eye of the carver. Though the head-rest seemed beautiful, I still don’t know if I was admiring as an essentially expressive object some simple item of practical use, or something that combined expression and utility.

In this quite modestly ambitious essay, I'll generally just assume that, for the most part, our "scientifically informed" commonsense view of the world is true. Just as it is with such unthinking things as planets, plates and, I suppose, plants, too, so it also is with all earthly thinking beings, from people to pigs and pigeons; each occupies a region of space, however large or small, in which all are spatially related to each other. Or, at least, so it is (...) with the bodies of these beings. And, even as each of these ordinary entities extends through some space, so, also, each endures through some time. In line with that, each ordinary entity is at least very largely, and is perhaps entirely, an enduring physical entity (which allows that many might have certain properties that aren't purely physical properties.) Further, each ordinary enduring entity is a physically complex entity: Not only is each composed of parts, but many of these parts, whether or not absolutely all of them, are themselves enduring physical entities, and many of them also are such physically complex continuing entities. When an ordinary entity undergoes a significant change, then, at least generally, this change will involve changes concerning that entity's constituting physical parts, whether it be a rearrangement of (some of) these parts, or a loss of parts, or a gain of parts, or whatever. Often, the entity will still exist even after the change occurs. As we may well suppose, this happens when, from two strokes of an ax, an ordinary log loses just a chip of wood. As we may then say, such a change conforms with the log's "persistence conditions." Somewhat less often, such an ordinary entity undergoes a change that means an end to it: When a bomb's explosion makes our log become just so many widely scattered motes of dust, the log will no longer exist. Such a momentous change doesn't conform with the log's persistence conditions. (shrink)

STILLWATER, MINNESOTA—Two men sit at a long table, oblivious to the breakfast-time commotion. One moves a coffee cup from one side of a water glass to the other. “If I look here and don’t see the cup,” he says to the other, “then I know it must be there.” It sounds like a “deep” exchange between swotty young philosophy majors. But the fellow moving the cup has gray hair— and a Nobel Prize in physics. Sliding the porcelain, Anthony Leggett of (...) the University of Illinois, Urbana-Champaign, explains how scientists might try to see past the strictures of quantum mechanics, the bizarre theory that governs the behavior of tiny objects and clashes with our everyday notions of reality. “None of the existing interpretations of quantum mechanics as a theory of the entire world is satisfactory,” Leggett says to John Preskill, a physicist at the California Institute of Technology in Pasadena. Leggett, Preskill, and 22 other physicists, philosophers, and historians have gathered here for the Seven Pines Symposium.* Packed into a slightly ramshackle lodge in a wooded state park, the scholars—all of them men—will share their insights, suites of rooms without telephones, and meals of roast quail and pheasant at a long communal table. Perhaps not since the famous Solvay Conferences of the early 20th century, at which Niels Bohr and Albert Einstein debated the meaning of quantum theory in their free time, has physics seemed so genteel. Each year, the symposium tackles another of physics’ enduring puzzles: the nature of the vacuum, the concept of a f ield, the meaning of time. The aim is not to resolve the mysteries but to seed new lines of inquiry, says Roger Stuewer, a historian at the University of Minnesota, Twin Cities, and chair of the symposium’s advisory board. “When we get the best people together,” he says, “ideas are planted that in some intangible way will influence what they do in the future.” Those germinating ideas are watered with a mellow Zinfandel and nourished with succulent steak. This year, attendees spent 5 days grappling with the implications of quantum mechanics, which have perplexed physi.. (shrink)
Philosophers on Education provides the most comprehensive history of philosphers' views and impacts on the direction of education, from Plato to Dewey. As Amelie Oksenberg Rorty explains in describing a history of education, we are essentially describing and gaining the clearest understanding of the issues that presently concern and divide us. Philosophical reflection on education has usually been directed to the education of rulers, to those who are presumed to preserve and transmit--or to redirect and transform--the culture of sociey, its (...) knowledge and values. Every historical era is marked by a struggle among claimants to that power. It is only late in the history of liberal democracies that educational policy was formulated for and directed toward autonomous individuals who structure their own lives. The contributors to this collection recognize that history remains actively embedded and expressed in society's beliefs and practices, and that the study of the history of philosophy mandates reflection on its implications for education. The all new essays are written by some of the finest contemporary philosophers: Elizabeth Anderson, Annette C. Baier, Frederick B. Beiser, Eva T. H. Brann, M.F.
