‘Physics and fashion’: John Tyndall and his audiences in mid-Victorian Britain

This paper explores how the physicist John Tyndall transformed himself from humble surveyor and schoolmaster into an internationally applauded icon of science. Beginning with his appointment as Professor of Natural Philosophy at the Royal Institution in 1853, I show how Tyndall’s worries about his social class and Irish origins, his painstaking attention to his lecturing performance and skilled use of the material and architectural resources of the Royal Institution were vital to his eventual success as a popular expositor and ambassador for science. Secondly I explore the implications of Tyndall’s ‘popularity’ with respect to debates over the meaning and value of scientific ‘popularisation’. In support of recent work challenging diffusionist models of science communication, I show how Tyndall’s interactions with his audiences illustrate the symbiotic relationship between producer and consumer of ‘popular’ science. By examining the views of Tyndall’s critics—notably the ‘North British’ group of physicists—and his defenders and rivals in the domain of popular scientific lecturing, I show that disputes over Tyndall’s authority reflected anxieties about what constituted popular science and the transient boundaries between instruction and entertainment. The term ‘popularisation’ enjoyed many different uses in these debates, not least of all as a rheorical device with which to either exalt or destroy a scientist’s credibility.     

Instruments and rules: R. B. Woodward and the tools of twentieth-century organic chemistry

The paper illustrates how organic chemists dramatically altered their practices in the middle part of the twentieth century through the adoption of analytical instrumentation — such as ultraviolet and infrared absorption spectroscopy and nuclear magnetic resonance spectroscopy — through which the difficult process of structure determination for small molecules became routine. Changes in practice were manifested in two ways: in the use of these instruments in the development of ‘rule-based’ theories; and in an increased focus on synthesis, at the expense of chemical analysis. These rule-based theories took the form of generalizations relating structure to chemical and physical properties, as measured by instrumentation. This ‘Instrumental Revolution’ in organic chemistry was two-fold: encompassing an embrace of new tools that provided unprecedented access to structures, and a new way of thinking about molecules and their reactivity in terms of shape and structure. These practices suggest the possibility of a change in the ontological status of chemical structures, brought about by the regular use of instruments. The career of Robert Burns Woodward (1917–1979) provides the central historical examples for the paper. Woodward was an organic chemist at Harvard from 1937 until the time of his death. In 1965, he won the Nobel Prize in Chemistry.     

Rehabilitating theory: refusal of the ‘bottom-up’ construction of scientific phenomena

In this paper I inquire into Bogen and Woodward’s (1988) data/phenomena distinction, which in a similar way to Cartwright’s construal of the model of superconductivity (1995)—although in a different domain—argues for a ‘bottom-up’ construction of phenomena from data without the involvement of theory. I criticise Bogen and Woodward’s account by analysing their melting point of lead example in depth, which is usually cited in the literature to illustrate the data/phenomenon distinction. Yet, the main focus of this paper lies on Matthias Kaiser’s (1995) case study of the plate tectonic revolution, the most extensive case study that has been put forth to support the bottom-up construction of phenomena. On the basis of new historical evidence, which has been overlooked not only by Kaiser but also by the entire historical literature on the plate tectonic revolution, I demonstrate that phenomena are not constructed from the bottom-up but rather, admittedly counter-intuitively, from the top-down.     

Can the constructive empiricist be a nominalist? Quasi-truth, commitment and consistency

In this paper, I explore Rosen’s (1994) ‘transcendental’ objection to constructive empiricism—the argument that in order to be a constructive empiricist, one must be ontologically committed to just the sort of abstract, mathematical objects constructive empiricism seems committed to denying. In particular, I assess Bueno’s (1999) ‘partial structures’ response to Rosen, and argue that such a strategy cannot succeed, on the grounds that it cannot provide an adequate metalogic for our scientific discourse. I conclude by arguing that this result provides some interesting consequences in general for anti-realist programmes in the philosophy of science.     

Weyl’s ‘agens theory’ of matter and the Zurich Fichte

This paper investigates Hermann Weyl’s reception of philosophical concepts stemming from the German Idealist Johann Gottlieb Fichte. In particular, Weyl’s ‘agens theory’ of matter, which he held around 1925, will be looked at. In the extant literature, the—admittedly also important—influence of Husserl on Weyl has mainly been addressed. Thus, apart from investigating some detailed Fichtean inheritances in Weyl’s concepts of causality, chance and continuity, the general difference which Weyl saw between the philosophies of Fichte and Husserl will also be discussed. For Weyl this is above all a difference between an active constructivism and a rather passive phenomenological seeing (Schau). Further, the paper shows in some detail the way Weyl was drawn into a certain reading of Fichte by his Zurich colleague, the philosopher Fritz Medicus. The methodological frame of the paper is that of Konstellationsforschung, a historical and systematic approach which proves to be particularly fruitful when investigating a (broadly speaking) German Idealist context and which allows special attention to be given to the acting subjects within the constellation under investigation. Conversely, Weyl’s agens theory suggests amendments to this methodology.     

Atomism, Poincaré and Planck

Planck's change in attitude to the question of whether atomic hypotheses were scientifically accessible, is discussed. It is argued contra Holton, that Planck's change in attitude to this question did not signal a methodological shift towards realism. The point of doing this is not just to investigate a significant episode in the history of quantum theory, but also to use the episode as a case study in support of a broader historical thesis. This thesis is that there was a widespread late-nineteenth century methodological tradition which motivated the change in status of certain ontological claims — e.g., that atoms exist — from ‘inaccessible to science’ to ‘scientifically acceptable’ even though those claims were not strictly ‘observable’. This methodological tradition is a hybrid of positivist and realist views. Thus, contrary to one popular view, the fin de siécle triumph of atomism is not to be seen as a triumph for a realist view of science Poincare's views are also used as an illustration.     

Revisiting Galison’s ‘Aufbau/Bauhaus’ in light of Neurath’s philosophical projects

In his article entitled ‘Aufbau/Bauhaus’ and related work, Peter Galison explores the connections between the Vienna Circle and the Dessau Bauhaus. Historically, these groups were related, with members of each group familiar with the ideas of the other. Galison argues that their projects are related as well, through shared political views and methodological approach. The two main figures that connect the Vienna Circle to the Bauhaus—and the figures upon which Galison focuses—are Rudolf Carnap and Otto Neurath. Yet, in our view, the connections that Galison develops do not properly capture the common themes between the Bauhaus and Neurath’s philosophical projects. In this paper, we will examine a few of the historical connections between the Dessau Bauhaus and the Vienna Circle, as well as the philosophical connections that Galison draws between these two groups. By examining in greater depth Neurath’s philosophical commitments, we aim to demonstrate that some of these philosophical connections fail to resonate with Neurath’s projects. And, finally, we develop different connections between Neurath’s projects and the Bauhaus. In our view, these new connections between Neurath and the Dessau Bauhaus are both substantive and philosophically interesting.     

History of Science through Koyré's Lenses

Alexandre Koyré was one of the most prominent historians of science of the twentieth century. The standard interpretation of Koyré is that he falls squarely within the internalist camp of historians of science—that he focuses on the history of the ideas themselves, eschewing cultural and sociological interpretations regarding the influence of ideologies and institutions on the development of science. When we read what Koyré has to say about his historical studies (and most of what others have said about them), we find him embracing and championing this Platonic view of his work. Ultimately I think this interpretation of Koyré's history of science is lopsided and in need of correction. I claim, rather, that a careful reading of Koyré's work suggests that a tension exists between internal and external methodological considerations. The external considerations stem from Koyré's commitment to the unity of human thought and the influence he admits that the ‘transscientifiques’ (philosophy, metaphysics, religion) have on the development of science. I suggest in conclusion then, that if we are to put a philosophical label on his work, rather than ‘Platonist’, as has been the custom, ‘Hegelian’ makes a better fit.     

Science, truth and history, Part I. Historiography, relativism and the Sociology of Scientific Knowledge

Recently, many historians of science have chosen to present their historical narratives from the ‘actors’-eye view’. Scientific knowledge not available within the actors’ culture is not permitted to do explanatory work. Proponents of the Sociology of Scientific Knowledge (SSK) purport to ground this historiography on epistemological relativism. I argue that they are making an unnecessary mistake: unnecessary because the historiographical genre in question can be defended on aesthetic and didactic grounds; and a mistake because the argument from relativism is in any case incoherent.The argument of the present article is self-contained, but steers clear of metaphysical debates in the philosophy of science. To allay fears of hidden assumptions, the sequel, to be published in the following issue, will consider SSK’s prospects of succour from scientific realism, instrumentalism, and a metaphysical system of Bruno Latour’s own devising.     

Scientific realism bit by bit: part I. Kitcher on reference

In this paper, I consider Kitcher’s (1993) account of reference for the expressions of past science. Kitcher’s case study is of Joseph Priestley and his expression ‘dephlogisticated air’. There is a strong intuitive case that ‘dephlogisticated air’ referred to oxygen, but it was underpinned by very mistaken phlogiston theory, so concluding either that dephlogisticated air referred straightforwardly or that it failed to refer both have unpalatable consequences. Kitcher argues that the reference of such terms is best considered relative to each token—some tokens refer, and others do not. His account thus relies crucially on how this distinction between tokens can be made good—a puzzle I call the discrimination problem. I argue that the discrimination problem cannot be solved. On any reading of Kitcher’s defence of the distinction, the grounds provided are either insufficient or illegitimate. On the first reading, Kitcher violates the principle of humanity by making Priestley’s referential success a matter of the mental contents of modern speakers. The second reading sidesteps the problem of beliefs by appealing to mind-independent facts, but I argue that these are insufficient to achieve reference because of the indeterminacy introduced by the qua problem. On the third and final reading, Priestley’s success is given by what he would say in counterfactual circumstances. I argue that even if there are facts about what Priestley would say, and there is reason for doubt, there is no motivation to think that such facts determine how Priestley referred in the actual world.     

François Viète: between analysis and cryptanalysis

François Viète is considered the father both of modern algebra and of modern cryptanalysis. The paper outlines Viète’s major contributions in these two mathematical fields and argues that, despite an obvious parallel between them, there is an essential difference. Viète’s ‘new algebra’ relies on his reform of the classical method of analysis and synthesis, in particular on a new conception of analysis and the introduction of a new formalism. The procedures he suggests to decrypt coded messages are particular forms of analysis based on the use of formal methods. However, Viète’s algebraic analysis is not an analysis in the same sense as his cryptanalysis is. In Aristotelian terms, the first is a form of ‘’, while the second is a form of . While the first is a top-down argument from the point of view of the human subject, since it is an argument going from what is not actual to what is actual for such a subject, the second one is a bottom-up argument from this same point of view, since it starts from what is first for us and proceed towards what is first by nature.     

Collecting airs and ideas: Priestley’s style of experimental reasoning

It has often been claimed that Priestley was a skilful experimenter who lacked the capacities to analyze his own experiments and bring them to a theoretical closure. In attempts to revise this view some scholars have alluded to Priestley’s ‘synoptic’ powers while others stressed the contextual role of British Enlightenment in understanding his chemical research. A careful analysis of his pneumatic reports, privileging the dynamics of his experimental practice, uncovers significant yet neglected aspects of Priestley’s science. By focusing on his early experimental conduct and writing on nitrous air, I demonstrate how his methodological and rhetorical devices, far from being consequences of compulsive writing or theoretical naïveté, were deeply entwined with his chemical research. I employ the notion of ‘style of experimental reasoning’ (SER)—derived from A. C. Crombie and I. Hacking—to shed light on the intersection at which Priestley’s unique method, literary style, and epistemology converged to generate scientific knowledge. Establishing Priestley’s SER advances a finer understanding of the interactive character of his pneumatic experimentalism, peculiar dimensions of which have evaded both traditional as well as revisionist scholarship, thus infusing the longstanding historiographic debate over his scientific merits.     

Primary source knowledge and technical decision-making: Mbeki and the AZT debate

Demands for public participation in technical decision-making are currently high on the agenda of Science & Technology Studies. It is assumed that the democratisation of technical decision-making processes generally leads to more socially desirable and acceptable outcomes. While this may be true in certain cases, this assumption cannot be generalised. I will discuss the case of the so-called ‘South African AZT debate’. The controversy started when President Thabo Mbeki, after reading some scientific papers on the toxicity of AZT, decided to bar the use of the drug in the public health sector as a means to reduce the transmission of HIV from mothers to children. While the scientific mainstream accepts the effectiveness of AZT in reducing the risk of vertical HIV transmission, a few maverick scientists reject the clinical evidence and argue that the risks of using AZT by far outweigh its benefits. Based on various textual sources and using the ‘Periodic Table of Expertises’ developed by Collins and Evans, Mbeki’s expertise at the time of his intervention into the technical question whether AZT is a medicine or a poison can be classified as primary source knowledge. It is shown that this type of expertise is insufficient for technical decision-making. Mbeki’s primary source knowledge legitimated his presentation of the claims of maverick scientists as a serious contribution to the debate—with tragic consequences for tens of thousands of babies.     

Trading zones and interactional expertise

The phrase ‘trading zone’ is often used to denote any kind of interdisciplinary partnership in which two or more perspectives are combined and a new, shared language develops. In this paper we distinguish between different types of trading zone by asking whether the collaboration is co-operative or coerced and whether the end-state is a heterogeneous or homogeneous culture. In so doing, we find that the voluntary development of a new language community—what we call an inter-language trading zone—represents only one of four possible configurations. In developing this argument we show how different modes of collaboration result in different kinds of trading zone, how different kinds of trading zone may be ‘nested’ inside each other and discuss how a single collaboration might move between different kinds of trading zone over time. One implication of our analysis is that interactional expertise is a central component of at least one class of trading zone.     

Thomas Reid and the problem of induction: from common experience to common sense

By the middle of the eighteenth century the new science had challenged the intellectual primacy of common experience in favor of recondite, expert and even counter-intuitive knowledge increasingly mediated by specialized instruments. Meanwhile modern philosophy had also problematized the perceptions of common experience — in the case of David Hume this included our perception of causal relations in nature, a fundamental precondition of scientific endeavor.In this article I argue that, in responding to the ‘problem of induction’ as advanced by Hume, Reid reformulated Aristotelian foundationalism in distinctly modern terms. An educator and mathematician self-consciously working within the framework of the new science, Reid articulated a philosophical foundation for natural knowledge anchored in the human constitution and in processes of adjudication in an emerging modern public sphere of enlightened discourse. Reid thereby transformed one of the bases of Aristotelian science — common experience — into a philosophically and socially justified notion of ‘common sense’. Reid's intellectual concerns had as much to do with the philosophy of science as they did with moral philosophy or epistemology proper, and were bound up with wider social and scientific changes taking place in the early modern period.     

The development of the Neurath principle: unearthing the Romantic link

Otto Neurath’s thoroughgoing anti-foundationalism is connected to the recognition that protocol sentences are not inviolable, that is they are fallible and their choice cannot be determined: ‘Poincaré, Duhem and others have adequately shown that even if we have agreed on the protocol statements, there is a not limited number of equally applicable, possible systems of hypotheses. We have extended this tenet of the uncertainty of systems of hypotheses to all statements, including protocol statements that are alterable in principle’ (Neurath, 1983, p. 105). Later historiography has called Neurath’s extension of Duhemian holism the Neurath principle. Based on a study of Neurath’s early works on the history of optics, the paper investigates a previously unnoticed influence on the development of this principle, Neurath’s reading of Goethe’s Theory of colours. The historical and polemical parts of Goethe’s tripartite book provided Neurath with ideal examples for the vertical extension of Duhem’s thesis to observation statements. Moreover, Goethe’s critique of the language of science and his views on the theory-ladenness of observation, as well as on the history of science show strong parallels to many of Neurath’s ideas. These demonstrate the existence of surprisingly direct textual links between Romantic views on science and the development of twentieth-century philosophy of science. Neurath’s usage of Goethe’s examples also indicates that the birth of the Neurath principle is more tightly connected to actual scientific practice than to theory-testing, and that by admitting the theory-ladenness of observation reports and fallibility of protocol statements Neurath does not throw empiricism overboard.     

Legend naturalism and scientific progress: An essay on Philip Kitcher's : The advancement of science

Philip Kitcher's The Advancement of Science sets out, programmatically, a new naturalistic view of science as a process of building consensus practices. Detailed historical case studies—centrally, the Darwinian revolutio—are intended to support this view. I argue that Kitcher's expositions in fact support a more conservative view, that I dub ‘Legend Naturalism’. Using four historical examples which increasingly challenge Kitcher's discussions, I show that neither Legend Naturalism, nor the less conservative programmatic view, gives an adequate account of scientific progress. I argue for a naturalism that is more informed by psychology and a normative account that is both more social and less realist than the views articulated in The Advancement of Science.     

On the continuity of reference of the elements: a response to Hendry

Robin Hendry has recently argued that although the term ‘element’ has traditionally been used in two different senses (basic substance and simple substance), there has nonetheless been a continuity of reference. The present article examines this author’s historical and philosophical claims and suggests that he has misdiagnosed the situation in several respects. In particular it is claimed that Hendry’s arguments for the nature of one particular element, oxygen, do not generalize to all elements as he implies. The second main objection is to Hendry’s view that the qua problem can be illuminated by appeal to the intention of scientists.     

Comment on ‘Stapp's theorem without counterfactual commitment’

Michael Dickson has examined the ‘could’ version of my nonlocality theorem, and claims to have found a flaw. Several errors in his argument are pointed out. The main problem is that he replaces my locality criterion by a substitute that is too weak to do the job. His justification for making this change is critically flawed by a failure to differentiate my sufficient condition from the converse necessary condition. Nevertheless, Dickson succeeds in deriving all but the final step of my argument. My justification for this final crucial step is discussed here in some detail.
