The letter sent by the Royal Society to the London optician, John Marshall, in 1694, commending his new method of grinding, has been reprinted, and referred to, in recent years. However, there has been no comprehensive analysis of the method itself, the letter and the circumstances in which it was written, nor the consequences for trade practices. The significance of the approval by the Royal Society of this innovation and the use of that approbation by John Marshall and other practitioners (...) are examined. Gaps in existing accounts of Marshall's method are partly remedied by supplementing surviving written materials with accounts of contemporary, and present-day, trade practices based on his method. The reasons why Marshall and his contemporaries failed to record his method and specify his improvements are discussed. The reactions of the Spectacle Makers' Company and its more prominent members, both to the innovation itself and to the Royal Society's letter, are analysed. The impact of the new technique on contemporary and later opticians is described. (shrink)

The paper examines the structure of the mathematical instrument making trade in London from the mid-sixteenth century to the opening of the Hanoverian era. This analysis of the trade is primarily based on evidence drawn from contemporary advertising. A distinction between informal editorial recommendations and advertising per se is made. It is concluded that up to the mid-seventeenth century mathematical instrument makers worked in either wood or metal. After that date a growing number of workshops advertised that they manufactured in (...) all media. Advertising was aimed at informing professional users from whom particular instruments could be purchased, but not on informing customers in specific terms of the range of instruments manufactured. It is concluded that until the early eighteenth century most mathematical instruments were commissioned. Only towards the end of the period is there evidence of over-the-counter sales, and advertising aimed at encouraging the growing consumer market to buy mathematical instruments for the practice of science as a social or recreational activity.

SummaryRecent studies have confirmed the traditional attribution of the invention of the balance barometer to Sir Samuel Morland. Two contemporary references to a 1678 printed pamphlet describing the invention are known but no copy has been located. This paper prints a seventeenth century manuscript copy of Morland's description of his balance barometer. The commentary outlines Robert Hooke's role in the invention. Morland's analysis of the mode of action of the instrument is considered in the light of contemporary comprehension of the (...) barometric phenomennon. (shrink)

In 1736 Colin MacLaurin, Professor of Mathematics in the University of Edinburgh petitioned the Town Council for permission to erect an astronomical observatory in the College to broaden the research and teaching base of the University. After MacLaurin's death, the Town Council and University Senate, more concerned with the promotion of the Infirmary and associated medical teaching, took no further action. The funds raised by MacLaurin were lent to his successor, and largely dissipated. In 1776 the balance was transferred to (...) the proposed Calton Hill Observatory. This private scheme was to be financially self-sufficient, generating income from the casual visitor and fees charged to students. It too failed. Funds were wasted on unnecessary architectural elaboration, the Town Council failed to meet their financial obligations, the University acquiesced in the total inactivity of the Regius Professor of Astronomy, whilst the commercial management-base of the Observatory vitiated any serious scientific activity.

In this article the perspective shifts to the “upstream” end of the agricultural knowledge and information system (AKIS). Because knowledge policy and strategic decision-making are not the prerogative of the public sector, organizations such as cooperative unions and multinational companies are included. After considering the influence of the changing environment on the nature of the AKIS, the role of knowledge management and policy in the emerging knowledge and information market is examined. Special attention is given to public and private R&D. (...) The article then looks where information technology (IT) fits in and what considerations determine strategic investment in IT projects and sustained services. Some of the European experiences with this strategic investment are evaluated. (shrink)

" Waldie speculates on the meanings and implications of the snapshots in this book and of snapshots generally, which he sees as expressions of "the hunger of memory.".

Multiple -conclusion logic extends formal logic by allowing arguments to have a set of conclusions instead of a single one, the truth lying somewhere among the conclusions if all the premises are true. The extension opens up interesting possibilities based on the symmetry between premises and conclusions, and can also be used to throw fresh light on the conventional logic and its limitations. This is a sustained study of the subject and is certain to stimulate further research. Part I reworks (...) the fundamental ideas of logic to take account of multiple conclusions, and investigates the connections between multiple - and single - conclusion calculi. Part II draws on graph theory to discuss the form and validity of arguments independently of particular logical systems. Part III contrasts the multiple - and the single - conclusion treatment of one and the same subject, using many-valued logic as the example; and Part IV shows how the methods of 'natural deduction' can be matched by direct proofs using multiple conclusions.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Transcendental Phenomenology as Human Possibility: Husserl and Fink on the Phenomenologizing Subject by Denis DŽANIĆD. J. HobbsDŽANIĆ, Denis. Transcendental Phenomenology as Human Possibility: Husserl and Fink on the Phenomenologizing Subject. Cham: Springer, 2023. x + 236 pp. Cloth, $119.99Denis Džanić’s Transcendental Phenomenology as Human Possibility, despite its superficially historical focus on a specific period of collaboration between Edmund Husserl and his somewhat wayward protégé Eugen Fink, addresses key (...) systematic issues in transcendental phenomenology, namely, how the act of phenomenologizing should be understood in connection with the specific human beings who aim to become phenomenologists, and what the answer to this question tells us about both the genuine subject of phenomenology and the motivation for phenomenologizing. These questions are important for our understanding of not only the historical development of phenomenology but also the practice and goals of phenomenology—specifically, for a conception of phenomenologizing as a project in which we, as particular, historical, empirical figures, might want to engage.Much of the book focuses on laying the groundwork for understanding these complicated issues both historically and systematically. Džanić does an admirable job of tracing the rapidly evolving interactions between Husserl and Fink, both as intellectual collaborators on this philosophical project and as a pair of very human figures who ultimately found themselves pursuing quite different solutions to the problems of the subject and origin of phenomenology. He focuses particularly on the Sixth Cartesian Meditation, Fink’s attempt to extend Husserl’s famous text to include a phenomenology of the act of phenomenologizing itself (including Husserl’s marginal comments on the text), although he draws on a number of other significant texts and manuscripts (mostly Husserl’s, albeit with an extended aside on Heidegger) wherever they are helpful for explicating the complex evolution of Husserl’s thought on the subject. Admittedly, the book thus takes on a challenging task—both because of the difficult nature of this topic and because of the obscurity of the technical terms required to discuss it. However, despite the necessarily enigmatic character of the relevant language, Džanić’s attempts to explore the main outlines of this issue are worthwhile, particularly due to his ability to resist the temptation to view Husserl’s thought here as monolithic.In the early chapters, Džanić explicates in detail the rather complicated solution that Fink proposed to this difficulty, namely, the abandonment (to some extent) of the ultimately human origin of phenomenology in favor of a fundamentally nonhuman (and eventually meontic) conception of the transcendental ego, which generated a great deal of elaborate and (at least in the Sixth Meditation) inadequately supported speculation. For Fink, both the motivation to phenomenologize and the act of phenomenologizing itself ultimately stem from a source that is fundamentally prior to—in a(n onto)logical rather than temporal sense—any empirical ego or empirical act of phenomenologizing, a source that merely “enworlds” itself (in various complicated senses that Džanić does [End Page 145] an admirable job of clarifying) in the apparently anthropologistic, everyday world of individual phenomenologists. Džanić calls this interpretation of phenomenology Fink’s “epistemological anti-humanism,” and it serves as the basis for one potential (radically anti-Heideggerian but nevertheless somewhat disappointing) solution to the question of why we should phenomenologize at all. As Džanić notes, this solution was at least briefly taken up by Fink’s mentor Husserl himself, although the degree to which Husserl actually endorsed this path beyond the level of a fleeting flirtation remains questionable. Ultimately, as Džanić rightly highlights and as becomes abundantly clear in Husserl’s (often rather scathing) notes on Fink’s Sixth Cartesian Meditation, he abandoned this interpretation.Accordingly, in the later chapters of the book, Džanić traces Husserl’s ultimate development of a quite different solution to the problems of the origin and motivation of phenomenology—a solution that, unlike his brief foray into Finkian grandeur, views the act of phenomenologizing as essentially rooted in human possibility (that is, as part of the famous lifeworld that features so prominently in Husserl’s work, especially in the Crisis and other late texts). After his collaboration with and... (shrink)

This article seeks to present Vygotsky's theoretical perspective as an integral whole as an antidote to the desire to plunder his work for isolated insights. The first part of the paper treats Vygotsky's views on method: his critique of the prevailing psychological orthodoxies; his recommendation that the higher mental functions be seen as standing in interfunctional relations of mutual determination; his technique of 'unit analysis'. The second part discusses the method in action: Vygotsky's genetic account of the development of consciousness, (...) on which the key point in ontogenesis is taken to be the convergence of two intitially independently developing faculties: thought and speech; the notion of internalisation and its defence; the critique of Piaget; the concept of 'inner speech' and developed thought. The author hopes this article will serve as an aid to reading the limited sources of Vygotsky's writings presently available in English. (shrink)

In his 1922/1923 articles for the Japanese magazine _Kaizō_, Edmund Husserl identifies a particular “humanity” or human culture by the purposeful idea [_Zweckidee_] consciously embraced by the community. This purposeful idea is attained through rational self-formation on the part of the community in a manner analogous to the rational self-formation of the individual human being. Thereafter, it can be referenced to distinguish different cultures (or stages of cultural development) from one another through its objective manifestation in communal groups and cultural (...) products, as Husserl retraces in a historical account of the development of Western history. This paper explores the essential character of this conception of the purposeful idea from both an exegetical and a systematic perspective, examining in particular the relationship between such an idea and the values experienced by individual subjects within a culture (which are, according to Husserl, also available at the level of objective culture in relation to a communal subject). The paper argues that Husserl’s basic conception of the purposeful idea is a good model for understanding certain essential characteristics of cultural constitution in general, although some of his fundamental assumptions—especially the strict identity he attempts to establish between a purposeful idea as such and the specific goal of universal, rational self-understanding—turn out to be somewhat more questionable in light of the connection between the purposeful idea and the genuinely felt values underlying it.

Artificial insemination using the husband's semen (AIH) has always seemed more acceptable than the same procedure using donor semen. However, the layman may not even have thought of the legal problems or the moral dilemma if in fact a woman is inseminated using her husband's frozen semen after his death. In the USA there are already sperm banks set up by private individuals, generally for the use of those marriage partners when the husband has had a vasectomy and afterwards a (...) child is desired. If such private sperm banks were set up in Britain complex legal problems would follow, quite apart from the moral issue as to whether it was desirable to bring a child into the world deliberately having deprived him of a father from the start. These are the issues which Mr Cusine thinks should be carefully considered before doctors, lawyers and the women potentially concerned are confronted with a new dilemma. (shrink)

ABSTRACTOne long-running conundrum in Husserlian phenomenology revolves around the question of the identity of what Husserl calls the transcendental ego, a mysterious figure that he identifies as the subject of a genuinely transcendental phenomenology. In dialogue with both Husserl and his assistant and collaborator Eugen Fink, I attempt in this article to give a solid account of the identity of this transcendental ego, and in particular to explain the connection between this figure and the empirical ego of the individual phenomenologist. (...) I make particular reference to Fink's depiction of a "personal union" between these two egos in his Sixth Cartesian Meditation and to certain unclear hints in Husserl's 1923/1924 lectures on First Philosophy. Ultimately, I develop my own account of such a union, which explains the transcendental ego as a certain mode in which the phenomenologist might investigate his own experiences. On this basis, I argue, the status of phenomenology as a transcendental discipline can be understood without subjecting that discipline to certain criticisms that have been levelled against it.

This paper is written in an analytic style, but it is meant to deprive analysis of an important prop. The title needs a short introduction. The mistake is to take ‘real’ as governed in its separate uses by criteria; and this paper is meant to show that this is a mistake and that Ausin makes it. In the course of the argument I try to develop my own account and, although I am not altogether satisfied with it, the result gives (...) something to build upon. I believe the mistake is by no means confined to Austin, but that it is connected with a particular conception of philosophy. (shrink)

Recent studies using functional magnetic resonance imaging of patients in a vegetative state have raised the possibility that such patients retain some degree of consciousness. In this paper, the ethical implications of such findings are outlined, in particular in relation to decisions about withdrawing life-sustaining treatment. It is sometimes assumed that if there is evidence of consciousness, treatment should not be withdrawn. But, paradoxically, the discovery of consciousness in very severely brain-damaged patients may provide more reason to let them die. (...) Although functional neuroimaging is likely to play an increasing role in the assessment of patients in a vegetative state, caution is needed in the interpretation of neuroimaging findings. (shrink)
