The thesis is concerned with the outline of an ontology which admits only particulars and with the persistence of particulars through time. In Chapter 1 it is argued that a neglected class of particulars--the cases--have to be employed in order to solve the problem of universals, i.e., to give a satisfactory account of properties and kinds. In Chapter 2, two ways in which particulars could persist though time are distinguished. Difficulties are raised for the view that everything perdures through time, (...) i.e., the view that each persisting thing is a sum of continuous and dependent temporal parts. Objections to the view that people perdure are presented in Chapter 3, objections to the effect that such a view cannot capture salient truths about the nature of experience and wrongly implies that our special concern for ourselves, our friends and our familiars is irrational. An alternative account of persisting particulars is provided in Chapter 4 by way of given a theory of substances. Finally, in Chapter 5, this alternative account is applied to the issue of personal identity and to the issue of the identity over time of living things in general. A Hylomorphic View of living things is sketched and briefly defended. ;Throughout, certain themes recur: essentialism is taken to be relatively unproblematic, various connections between time and modality are exploited, reductionism is regarded as bearing the onus of proof, characterless entities such as prime matter, substrata, bare particulars and haecceities are rejected and the differences between the animate and the inanimate are emphasized.

Comments on an early version of Johnston's "The Problem with the Content View" (in Berit Brogaard ed. *Does Perception Have Content?*, 2014) delivered at a workshop on perception at NYU in 2010.

These are some responses to an early version of Johnston's paper "The Personite Problem" (now published in Nous).

This is a review of Johnston's book Surviving Death.

Mark Johnston’s book, Saving God (Princeton University Press, 2010) has two main goals, one negative and the other positive: (1) to eliminate the gods of the major Western monotheisms (Judaism, Christianity, and Islam) as candidates for the role of “the Highest One”; (2) to introduce the real Highest One, a panentheistic deity worthy of devotion and capable of extending to us the grace needed to transform us from inwardly-turned sinners to practitioners of agape. In this review, we argue (...) that Johnston’s attack on traditional forms of monotheism has less force than his criticism of the “undergraduate atheists” (e.g., Hitchens, Harris, Dawkins); and that his candidate for Highest One is not the greatest possible being, and so could not play the role Johnston casts for it. -/- .

Michael Tye proposed a way of understanding the content of hallucinatory experiences. Somewhat independently, Mark Johnston provided us with elements to think about the content of hallucination. In this paper, their views are compared and evaluated. Both their theories present intricate combinations of conjunctivist and disjunctivist strategies to account for perceptual content. An alternative view, which develops a radically disjunctivist account, is considered and rejected. Finally, the paper raises some metaphysical difficulties that seem to threaten any conjunctivist theory (...) and to lead the debate to a dilemma: strong disjunctivists cannot explain the subjective indistinguishability between veridical and hallucinatory experiences, whereas conjunctivists cannot explain what veridical and hallucinatory experiences have in common. This dilemma is left here as an open challenge. (shrink)

I critically discuss both the particular doctrinal and general meta-philosophical or methodological tenets of Mark Johnston's paper "Human Beings", attending to several weaknesses in his argument. One of the most important amongst them is an apparent reliance on a substitution of identicals within an intensional context as he argues that continuity of functioning brain is essential to the persistence of "Human Beings" as allegedly singled out by his methodology; another equally important is a simple lacuna in place of (...) an argument that candidate entities for re-identification by means we take for granted in the case of persons cannot be what I call "mentalistically" individuated.

Do mountains exist? The answer to this question is surely: yes. In fact, ‘mountain’ is the example of a kind of geographic feature or thing most commonly cited by English speakers (Mark, et al., 1999; Smith and Mark 2001), and this result may hold across many languages and cultures. But whether they are considered as individuals (tokens) or as kinds (types), mountains do not exist in quite the same unequivocal sense as do such prototypical everyday objects as chairs (...) or people.

Since it is only five years since the publication of our paper, "Geographical categories: An ontological investigation" (Smith and Mark 2001), it seems somewhat strange to be making retrospective comments on the piece. Nevertheless, the field is moving quickly, and much has happened since the article appeared. A large number of papers have already cited the work, which suggests that there is a seam here that people find worthy of being mined. In this short essay, we first review the (...) paper and attempt to assess its significance from the perspective of our current work. We then put the paper in the context of our individual and joint works, which led up to it, and summarize our research trajectories since the paper appeared, pointing out what some of this reveals about spatial ontology in general. We conclude with some remarks on the future of ontological research in geographical information science. (shrink)

The essay compares mark Johnston’s and Hilary Putnam’s approaches to the philosophy of religion in the framework of Charles Taylor’s claim that in modernity ”intermediate positions’ between theism and naturalism become increasingly attractive for a growing amount of people. both authors show that intermediate positions between naturalism and theism are conceptually plausible without having to deny that the conflicting worldviews are about a mind-independent reality. Johnston bridges the gap between naturalism and theism by developing a panentheistic worldview, (...) Putnam denies the necessity of bridging it by choosing an attitude toward the world that allows for the coexistence of at least partly incommensurable conceptualizations of what there is. In both cases the conceptual exploration of intermediate positions is fed by the authors’ commitment to intellectual integrity in coming to terms with the tension between scientific explanation and religious interpretation in the age of applied sciences.

This project continues our interdisciplinary research into computational and cognitive aspects of narrative comprehension. Our ultimate goal is the development of a computational theory of how humans understand narrative texts. The theory will be informed by joint research from the viewpoints of linguistics, cognitive psychology, the study of language acquisition, literary theory, geography, philosophy, and artificial intelligence. The linguists, literary theorists, and geographers in our group are developing theories of narrative language and spatial understanding that are being tested by the (...) cognitive psychologists and language researchers in our group, and a computational model of a reader of narrative text is being developed by the AI researchers, based in part on these theories and results and in part on research on knowledge representation and reasoning. This proposal describes the knowledge-representation and natural-language-processing issues involved in the computational implementation of the theory; discusses a contrast between communicative and narrative uses of language and of the relation of the narrative text to the story world it describes; investigates linguistic, literary, and hermeneutic dimensions of our research; presents a computational investigation of subjective sentences and reference in narrative; studies children’s acquisition of the ability to take third-person perspective in their own storytelling; describes the psychological validation of various linguistic devices; and examines how readers develop an understanding of the geographical space of a story.

The term “technological fix”, coined by technologist/administrator Alvin Weinberg in 1965, vaunted engineering innovation as a generic tool for circumventing problems commonly conceived as social, political or cultural. A longtime Director of Oak Ridge National Laboratory, government consultant and essayist, Weinberg also popularized the term “Big Science” to describe national goals and the competitive funding environment after the Second World War. Big Science reoriented towards Technological Fixes, he argued, could provide a new “Apollo project” to address social problems of the (...) future. His ideas – most recently echoed in “solutionism” – have channeled confidence and controversy ever since. This paper traces the genesis and promotion of the concept by Weinberg and his contemporaries. It argues that, through it, the marginal politics and technological confidences of interwar scientists and technocrats were repositioned as mainstream notions closer to the heart of Big Science policy.

This paper traces how media representations encouraged enthusiasts, youth and skilled volunteers to participate actively in science and technology during the twentieth century. It assesses how distinctive discourses about scientific amateurs positioned them with respect to professionals in shifting political and cultural environments. In particular, the account assesses the seminal role of a periodical, Scientific American magazine, in shaping and championing an enduring vision of autonomous scientific enthusiasms. Between the 1920s and 1970s, editors Albert G. Ingalls and Clair L. Stong (...) shepherded generations of adult ‘amateur scientists’. Their columns and books popularized a vision of independent nonprofessional research that celebrated the frugal ingenuity and skills of inveterate tinkerers. Some of these attributes have found more recent expression in present-day ‘maker culture’. The topic consequently is relevant to the historiography of scientific practice, science popularization and science education. Its focus on independent nonprofessionals highlights political dimensions of agency and autonomy that have often been implicit for such historical (and contemporary) actors. The paper argues that the Scientific American template of adult scientific amateurism contrasted with other representations: those promoted by earlier periodicals and by a science education organization, Science Service, and by the national demands for recruiting scientific labour during and after the Second World War. The evidence indicates that advocates of the alternative models had distinctive goals and adapted their narrative tactics to reach their intended audiences, which typically were conceived as young persons requiring instruction or mentoring. By contrast, the monthly Scientific American columns established a long-lived and stable image of the independent lay scientist. (shrink)

Cognitive categories in the geographic realm appear to manifest certain special features as contrasted with categories for objects at surveyable scales. We have argued that these features reflect specific ontological characteristics of geographic objects. This paper presents hypotheses as to the nature of the features mentioned, reviews previous empirical work on geographic categories, and presents the results of pilot experiments that used English-speaking subjects to test our hypotheses. Our experiments show geographic categories to be similar to their non-geographic counterparts in (...) the ways in which they generate instances of different relative frequencies at different levels. Other tests, however, provide preliminary evidence for the existence of important differences in subjects’ categorizations of geographic and non-geographic objects, and suggest further experimental work especially with regard to the role in cognitive categorization of different types of object-boundaries at different scales.

The philosophical study of irrationality can yield interesting insights into the human mind. One provocative issue is self-defeating behaviours, i.e. behaviours that result in failure to achieve one’s apparent goals and ambitions. In this paper I consider a self-defeating behaviour called choking under pressure, explain why it should be considered irrational, and how it is best understood with reference to skills. Then I describe how choking can be explained without appeal to a purely Freudian subconscious or ‘sub-agents’ view of mind. (...) Finally, I will recommend an alternative way to understand self-defeating behaviour which comes from a synthesis of Peter Strawson’'s explanation of ‘self-reactive attitudes’, Mark Johnston’'s notion of ‘mental tropisms’, and revised Freudian descriptions of the causes of self-defeating behaviour.

There has been a growing worry that perdurantism—and similarly ontologically abundant views—is morally untenable. For perdurantism posits that, coinciding with persons, are person-like objects, and giving them their moral due seems to require giving up prudentially driven self-sacrifice. One way to avoid this charge is to adopt consequentialism. But Mark Johnston has argued that the marriage of consequentialism and perdurantism is in moral trouble. For, depending on the nature of time, consequentialist perdurantists either are unable to do more (...) than one good act or they are morally obliged to adopt a repugnant form of ageism. I argue both that perdurantist consequentialism doesn’t have the latter implication, and that there’s at least one plausible form of consequentialism that perdurantists can adopt to avoid the former implication.

We propose as a UCGIS research priority the topic of “Ontological Foundations for Geographic Information.” Under this umbrella we unify several interrelated research subfields, each of which deals with different perspectives on geospatial ontologies and their roles in geographic information science. While each of these subfields could be addressed separately, we believe it is important to address ontological research in a unitary, systematic fashion, embracing conceptual issues concerning what would be required to establish an exhaustive ontology of the geospatial domain, (...) issues relating to the choice of appropriate methods for formalizing ontologies, and considerations regarding the design of ontology-driven information systems. This integrated approach is necessary, because there is a strong dependency between the methods used to specify an ontology, and the conceptual richness, robustness and tractability of the ontology itself. Likewise, information system implementations are needed as testbeds of the usefulness of every aspect of an exhaustive ontology of the geospatial domain. None of the current UCGIS research priorities provides such an integrative perspective, and therefore the topic of “Ontological Foundations for Geographic Information Science” is unique. (shrink)

On the historical origins of technological fixes and their wider social and political implications.

Analytic just war theorists often attempt to construct ideal theories of military justice on the basis of intuitions about imaginary and sometimes outlandish examples, often taken from non-military contexts. This article argues for a sharp curtailment of this method and defends, instead, an empirically and historically informed approach to the ethical scrutiny of armed conflicts. After critically reviewing general philosophical reasons for being sceptical of the moral-theoretic value of imaginary hypotheticals, the article turns to some of the special problems that (...) this method raises for appraisals of warfare. It examines some of the hypothetical examples employed in the construction of Jeff McMahan’s revisionist just war theory, and finds that they sometimes stipulate incompre- hensible conditions, lead to argumentative impasses of diverging yet uncertain intuitions, and distract attention away from the real problems of war as we empirically know it. In contrast, empirical and historical studies of warfare rein- force the deep connections between facts and values, and compel theorists to face uncomfortable moral ambiguities. Perhaps most importantly, the analytic method of focusing on imaginary hypothetical examples can not only be distracting, but it can also be genuinely dangerous. Hence, the article pays special attention to the way in which a seemingly innocuous fiction like the famous Ticking Time Bomb scenario can come to frame a new paradigm of inhumanity in the treatment of prisoners of war.

In "How to Speak of the Colors", Mark Johnston’s claims that eliminativism would require us to jettison colour discourse. In this paper, I challenge Johnston’s claim. I argue that a particular version of eliminativism, i.e., prescriptive colour fictionalism, allows us to continue employing colour discourse as we have thus far in the absence of colours. In doing so, it employs statistical models in its base discourse to derive high-level statistical constructs that can be linked to the fiction (...) via bridge principles. (shrink)

It would be terrible for us if humanity ceased to exist after we all die. But of course, eventually humanity will go out of existence. Does this result in a vicious regress if our flourishing hangs on what happens after us? Mark Johnston thinks so. In this note, I explain how Johnston's objection can be avoided. Briefly, our activities have a meaning horizon that extends for some generations after us. What matters is that we make a positive (...) difference to the lives of those generations, not that they themselves necessarily flourish. (shrink)

The actual and potential uses of holograms in museum displays, and the philosophy of knowledge and progress that they represent. Magazine journalists, museum curators, and historians sometimes face similar challenges in making topics or technologies relevant to wider audiences. To varying degrees, they must justify the significance of their subjects of study by identifying a newsworthy slant, a pedagogical role, or an analytical purpose. This chasse au trésor may skew historical story telling itself. In science and technology studies, the problem (...) potentially is worst for those subjects that do not retain an enduring capacity for spectacle or do not readily conform to templates of progress or economic importance. The case of holography is an excellent illustration of these points. An unusually wide-ranging subject, holography has attracted competing interpretations of intellectual novelty, technological application, and cultural significance. This paper examines the history of museum collections and exhibits of holography from the explosion of interest in the technique in 1964 to the end of the twentieth century. I argue that holography presents a particular challenge to museum collections and to popular representations of the history of science and technology. (shrink)

Atomic energy developed from 1940 as a subject shrouded in secrecy. Identified successively as a crucial element in military strategy, national status and export aspirations, the research and development of atomic piles (nuclear chain-reactors) were nurtured at isolated installations. Like monastic orders, new national laboratories managed their specialist workers in occupational environments that were simultaneously cosseted and constrained, defining regional variants of a new state-managed discipline: reactor technology. This paper discusses the significance of security in defining the new subject in (...) the USA, UK and Canada – wartime allies with similar political traditions but distinct trajectories in this field during the Cold War. The intellectual borders and content of the subject developed differently in each country, shaped under the umbrella of secrecy by disparate clusters of expertise, industrial traditions, and national goals. The nascent cadre was contained until the mid 1950s by classified publications and state-sponsored specialist courses. The early context of high security filtered its members and capped enduringly both their professional aspirations and public engagement. (shrink)

The nuclear engineer emerged as a new form of recognised technical professional between 1940 and the early 1960s as nuclear fission, the chain reaction and their applications were explored. The institutionalization of nuclear engineering channelled into new national laboratories and corporate design offices during the decade after the war, and hurried into academic venues thereafter proved unusually dependent on government definition and support. This paper contrasts the distinct histories of the new discipline in the USA and UK (and, more briefly, (...) Canada). In the segregated and influential environments of institutional laboratories and factories, historical actors such as physicist Walter Zinn in the USA and industrial chemist Christopher Hinton in the UK proved influential in shaping the roles and perceptions of nuclear specialists. More broadly, I argue that the State-managed implantation of the new subject within further and higher education curricula was shaped strongly by distinct political and economic contexts in which secrecy, postwar prestige and differing industrial cultures were decisive factors.

I argue that there is a flaw in the way that response-dependence has been formulated in the literature, and this flawed formulation has been correctly attacked by Mark Johnston’s Missing Explanation Argument (1993, 1998). Moving to a better formulation, which is analogous to the move from behaviourism to functionalism, avoids the Missing Explanation Argument.

This paper traces the role of American technocrats in popularizing the notion later dubbed the “technological fix”. Channeled by their long-term “chief”, Howard Scott, their claim was that technology always provides the most effective solution to modern social, cultural and political problems. The account focuses on the expression of this technological faith, and how it was proselytized, from the era of high industrialism between the World Wars through, and beyond, the nuclear age. I argue that the packaging and promotion of (...) these ideas relied on allegorical technological tales and readily-absorbed graphic imagery. Combined with what Scott called “symbolization”, this seductive discourse preached beliefs about technology to broad audiences. The style and conviction of the messages were echoed by establishment figures such as National Lab director Alvin Weinberg, who employed the techniques to convert mainstream and elite audiences through the end of the twentieth century.

Ontology, since Aristotle, has been conceived as a sort of highly general physics, a science of the types of entities in reality, of the objects, properties, categories and relations which make up the world. At the same time ontology has been for some two thousand years a speculative enterprise. It has rested methodologically on introspection and on the construction and analysis of elaborate world-models and of abstract formal-ontological theories. In the work of Quine and others this ontological theorizing in abstract (...) fashion about the world was supplemented by the study, based on the use of logical methods, of the ontological commitments or presuppositions embodied in scientific theories. In recent years both types of ontological study have found application in the world of information systems, for example in the construction of frameworks for knowledge representation and in database design and translation. As ontology is in this way drawn closer to the domain of real-world applications, the question arises as to whether it is possible to use empirical methods in studying ontological theories. More specifically: can we use empirical methods to test the ontological theories embodied in human cognition? We set forth the outlines of a framework for the formulation and testing of such theories as they relate to the specific domain of geographic objects and categories. (shrink)

This article explores the cultural contexts in which three-dimensional imaging has been developed, disseminated and used. It surveys the diverse technologies and intellectual domains that have contributed to spatial imaging, and argues that it is an important example of an interdisciplinary subject. Over the past century-and-a-half, specialists from distinct fields have devised explanations and systems for the experience of 3-D imagery. Successive audiences have found these visual experiences compelling, adapting quickly to new technical possibilities and seeking new ones. These complementary (...) interests, and their distinct perspectives, have co-evolved in lock-step. A driver for this evolution is visual culture, which has grown to value and demand the spectacular. As a result, professional and popular engagements with 3-D have had periods of both popularity and indifference, and cultural consensus has proven to be ephemeral. (shrink)

The emergence in Britain of chemical engineering, by mid‐century the fourth largest engineering specialism, was a hesitant and drawn out process. This article analyses the organisational politics behind the recognition of the technical occupation and profession from the First World War through to the end of the 1920s. The collective sense of professional identity among nascent ‘chemical engineers’ developed rapidly during this time owing to associations which promoted their cause among potential patrons. -/- .

In the large grey area between science and technology, specialisms emerge with associated specialists. But some specialisms remain ‘peripheral sciences’, never attaining the status of disciplines ensconced in universities, and their specialists do not become recognised professionals. A major social component of such side-lined sciences – one important grouping of techno-scientific workers – is the research-technology community. An important question concerning research-technology is to explain how the grouping survives without specialised disciplinary and professional affiliations. The case discussed illustrates the dynamics (...) of one such community. (shrink)

Holography, the three-dimensional imaging technology, was portrayed widely as a paradigm of progress during its decade of explosive expansion 1964–73, and during its subsequent consolidation for commercial and artistic uses up to the mid 1980s. An unusually seductive and prolific subject, holography successively spawned scientific insights, putative applications and new constituencies of practitioners and consumers. Waves of forecasts, associated with different sponsors and user communities, cast holography as a field on the verge of success—but with the dimensions of success repeatedly (...) refashioned. This retargeting of the subject represented a degree of cynical marketeering, but was underpinned by implicit confidence in philosophical positivism and faith in technological progressivism. Each of its communities defined success in terms of expansion, and anticipated continual progressive increase. This paper discusses the contrasting definitions of progress in holography, and how they were fashioned in changing contexts. Focusing equally on reputed ‘failures’ of some aspects of the subject, it explores the varied attributes by which success and failure were linked with progress by different technical communities. This important case illuminates the peculiar post-World War II environment that melded the military, commercial and popular engagement with scientific and technological subjects, and the competing criteria by which they assessed the products of science.

Canada, as one of the three Allied nations collaborating on atomic energy development during the Second World War, had an early start in applying its new knowledge and defining a new profession. Owing to postwar secrecy and distinct national aims for the field, nuclear engineering was shaped uniquely by the Canadian context. Alone among the postwar powers, Canadian exploration of atomic energy eschewed military applications; the occupation emerged within a governmental monopoly; the intellectual content of the discipline was influenced by (...) its early practitioners, administrators, scarce resources, and university niches; and a self-recognized profession coalesced later than did its American and British counterparts. This paper argues that the history of the emergence of Canadian nuclear engineers exemplifies unusually strong shaping of technical expertise by political and cultural context. (shrink)

Albert Abraham Michelson (1852-1931), the American optical physicist best known for his precise determination of the velocity of light and for his experiments concerning aether drift, is less often acknowledged as the creator of new spectroscopic instrumentation and new spectroscopies. He devised a new method of light analysis relying upon his favourite instrument – a particular configuration of optical interferometer – and published investigations of spectral line separation, Doppler-broadening and simple high-resolution spectra (1887-1898). Contemporaries did not pursue his method. Michelson (...) himself discarded the technique by the end of the decade, promoting a new device, the ‘echelon spectroscope’, as a superior instrument. High-resolution spectroscopy was taken up by others at the turn of the century using the echelon, Fabry-Pérot etalon and similar instruments. Michelson’s ‘Light Wave Analysis’ was largely forgotten, but was rediscovered c1950 and developed over the following three decades into a technique rechristened ‘Fourier transform spectroscopy’. This paper presents Michelson’s interferometric work as a continuum of personal interests and historical context as an example of 'research technology' and 'peripheral science'. (shrink)

On the origins of British chemical engineering,.

This paper explores the confrontation of physical and contextual factors involved in the emergence of the subject of color measurement, which stabilized in essentially its present form during the interwar period. The contentions surrounding the specialty had both a national and a disciplinary dimension. German dominance was curtailed by American and British contributions after World War I. Particularly in America, communities of physicists and psychologists had different commitments to divergent views of nature and human perception. They therefore had to negotiate (...) a compromise between their desire for a quantitative system of description and the perceived complexity and human-centeredness of color judgement. These debates were played out not in the laboratory but rather in institutionalized encounters on standards committees. Groups such as this constitute a relatively unexplored historiographic and social site of investigation. The heterogeneity of such committees, and their products, highlight the problems of identifying and following such ephemeral historical 'actors'. (shrink)

Two hundred and sixty-three subjects each gave examples for one of five geographic categories: geographic features, geographic objects, geographic concepts, something geographic, and something that could be portrayed on a map. The frequencies of various responses were significantly different, indicating that the basic ontological terms feature, object, etc., are not interchangeable but carry different meanings when combined with adjectives indicating geographic or mappable. For all of the test phrases involving geographic, responses were predominantly natural features such as mountain, river, lake, (...) ocean, hill. Artificial geographic features such as town and city were listed hardly at all for geographic categories, an outcome that contrasts sharply with the disciplinary self-understanding of academic geography. However, geographic artifacts and fiat objects, such as roads, cities, boundaries, countries, and states, were frequently listed by the subjects responding to the phrase something that could be portrayed on a map. In this paper, we present the results of these experiments in visual form, and provide interpretations and implications for further research. (shrink)

Between 1942 and the late 1950s, atomic piles (nuclear chain-reactors) were industrialized, initially to generate plutonium for the first atomic weapons and later to serve as copious sources of neutrons, radioisotopes and electrical power. These facilities entrained a new breed of engineering specialist adept at designing, operating and maintaining them. From the beginning, large companies supplied the engineering labor for this new technology, and played an important role in defining the nature of their nuclear expertise. In the USA, the most (...) influential company of the period was DuPont, which assumed responsibility for the first plutonium production reactors at Oak Ridge TN and Hanford WA between 1942-6, and of the postwar production facilities at Savannah River SC 1950-87. This paper explores the transition of authority from so-called “atomic scientists” to nuclear engineers at these sites, and the role played by DuPont in consolidating this new technical profession.

Dennis Gabor devised a new concept for optical imaging in 1947 that went by a variety of names over the following decade: holoscopy, wavefront reconstruction, interference microscopy, diffraction microscopy and Gaboroscopy. A well-connected and creative research engineer, Gabor worked actively to publicize and exploit his concept, but the scheme failed to capture the interest of many researchers. Gabor’s theory was repeatedly deemed unintuitive and baffling; the technique was appraised by his contemporaries to be of dubious practicality and, at best, constrained (...) to a narrow branch of science. By the late 1950s, Gabor’s subject had been assessed by its handful of practitioners to be a white elephant. Nevertheless, the concept was later rehabilitated by the research of Emmett Leith and Juris Upatnieks at the University of Michigan, and Yury Denisyuk at the Vavilov Institute in Leningrad. What had been judged a failure was recast as a success: evaluations of Gabor’s work were transformed during the 1960s, when it was represented as the foundation on which to construct the new and distinctly different subject of holography, a re-evaluation that gained the Nobel Prize for Physics for Gabor alone in 1971. This paper focuses on the difficulties experienced in constructing a meaningful subject, a practical application and a viable technical community from Gabor’s ideas during the decade 1947-1957.

Holography, the technology of three-dimensional imaging, has repeatedly been reconceptualised by new communities. Conceived in 1947 as a means of improving electron microscopy, holography was revitalized in the early 1960s by engineer-scientists at classified laboratories. The invention promoted the transformation of a would-be discipline (optical engineering) and spawned limited artist-scientist collaborations. However, a separate artisanal community promoted a distinct countercultural form of holography via a revolutionary technology: the sandbox optical table. Their tools, sponsorship, products, literature and engagement with wider culture (...) differentiated the communities, which instituted a limited ‘technological trade’. The subject strikingly illustrates the co-evolution of new technology along with highly dissimilar user groups, neither of which fostered the secure establishment of a profession or discipline. The case generalises the concept of 'research-technologists' and 'peripheral science', and extends the ideas of Langdon Winner by demonstrating how the political dimensions of a technology can be important but evanescent in the growth of technical communities.

Many naive realists endorse a negative disjunctivist strategy in order to deal with the challenge presented by the possibility of phenomenologically indistinguishable halucination. In the first part of this paper I argue that this approach is methodologically inconsistent because it undercuts the phenomenological motivation that underlies the the appeal of naive realism. In the second part of the paper I develop an alternative to the negative disjunctivist account along broadly Meinongian lines. In the last section of this paper I consider (...) and evaluate a somewhat similar but rival view of hallucination developed by Mark Johnston. (shrink)

On intellectual foundations that distinguished chemical engineering from other disciplines.

I discuss the early history of holography and explore how perceptions, applications, and forecasts of the subject were shaped by prior experience. I focus on the work of Dennis Gabor (1900–1979) in England,Yury N. Denisyuk (1927-2005) in the Soviet Union, and Emmett N. Leith (1927–2005) and Juris Upatnieks (b. 1936) in the United States. I show that the evolution of holography was simultaneously promoted and constrained by its identification as an analog of photography, an association that influenced its assessment by (...) successive audiences of practitioners, entrepreneurs, and consumers. One consequence is that holography can be seen as an example of a modern technical subject that has been shaped by cultural influences more powerfully than generally appreciated. Conversely, the understanding of this new science and technology in terms of an older one helps to explain why the cultural effects of holography have been more muted than anticipated by forecasters between the 1960s and 1990s.

The history of holography, the technology of three-dimensional imaging that grew rapidly during the 1960s, has been written primarily by its historical actors and, like many new inventions, its concepts and activities became surrounded by myths and myth-making. The first historical account was disseminated by the central character of this paper, George W. Stroke, while a professor of Electrical Engineering at the University of Michigan. His claims embroiled several workers active in the field of holography and information processing during the (...) 1960s, but transcended personality conflicts: they influenced the early historiography of holography and the awarding of the Nobel Prize for Physics to Dennis Gabor in 1971. An extended discussion of these episodes, based on archival research, publications analysis and interviews with participants, reveals the importance and extraordinary allure of intellectual priority for practicing scientists, and how its history and explanations are woven from multiple accounts and contemporary interpretations.

Holograms reached popular consciousness during the 1960s and have since left audiences alternately fascinated, bemused or inspired. Their impact was conditioned by earlier cultural associations and successive reimaginings by wider publics. Attaining peak public visibility during the 1980s, holograms have been found more in our pockets (as identity documents) and in our minds (as video-gaming fantasies and “faux hologram” performers) than in front of our eyes. The most enduring, popular interpretations of the word “hologram” evoke the traditional allure of magic (...) and galvanize hopeful technological dreams. This article explores the mutating cultural uses of the term “hologram” as marker of magic, modernity and optimism. (shrink)

The aesthetic skeptic maintains that it is futile to dispute about taste. One and the same work of art might appear beautiful to one person but repellent to another, and we have no reason to prefer one or another of these conflicting verdicts. Hume argues that the skeptic, however, moves too quickly. The crucial question is whether qualified critics will agree on their evaluations. And the skeptic fails to provide sufficient evidence that their verdicts will diverge. We have reason to (...) expect that a consensus will emerge over time, moreover, since aesthetic values are grounded on universal principles of human nature.
