Her concerns are not with the problems of skepticism, induction, or demarcation; she is concerned with how actual science achieves the suc- cesses it does, and what sort of metaphysical and epistemological presup- positions are needed to understand that success. Cartwright, like many working scientists themselves, takes a rather prag- matic/realist stance toward observations and interventions made by scien- tists and engineers and particularly toward their connections to causality: Scientists see impurities causing signal loss in a cable, and they stimulate an inverted population, causing it to lase. Given these starting points, there can be no question of a skeptical attitude toward causation, in either singular or generic form. The fundamental role (or better, roles) played by causation in scientific practice is undeniable; what Cartwright does, then, is reconfigure empiricism from the ground up based on this insight. In the reconfigura- tion process, many mainstays of the received view of science take a beating; especially, as we will see, the fundamentality of laws of nature. We will come back to this point, as well as Cartwright’s views on causation, below. Rather than claiming allegiance to some traditional philosophical stand- point, Cartwright likes to think of her work as an example of the practice of the Stanford School of history/philosophy of science. This school is formed by fortuitous spatiotemporal proximity and a family resemblance in phi- losophy styles; the best way to describe it is by listing its practitioners: Pat Suppes, John Dupré, Ian Hacking, Margaret Morrison, Peter Galison, and of course Nancy Cartwright. One thing that unites Stanford School practi- tioners is a strong respect for scientific practice—actual scientific practice, as displayed in the best examples of scientific discovery and creation. If science has delivered genuine knowledge about our world—as it surely has—then studying its actual practices is the surest guide to an understanding of how that knowledge is gained. Case studies are indispensable for philosophy of T&F Proofs: Not for Distribution 2 Carl Hoefer science. Though not an end in themselves, they are invaluable for keep- ing our metaphysical and methodological speculations on track with real science. Examples of this method are prominent in all three of Cartwright’s main books (HTLPL, NCATM, and DW).1 In the first book, Cartwright looks into the theory and engineering of lasers, finding that the fundamental, laws- driven “received view” of how such applied-physics items should relate to fundamental physics proves false at every turn. In the second book, econom- ics examples are brought to bear on the metaphysical issues of causation and capacities to show that economic practice can only make sense if read as presupposing the existence of stable causal capacities, over and above regu- larities and probabilities. In the third, the BCS model of superconductivity is examined with the aim of arguing that quantum mechanics is a theory with definite, built-inlimits in what it can pretend to cover—and hence no refuge for the beleaguered fundamentalist. Stanford School philosophers are usually “empiricists” in some broad use of the term but, unlike their teachers, do not shy away from metaphysics when it is built into, and hence justified by, successful scientific practice. In Cartwright’s work, metaphysics appears in some very specific guises con- cerning causation and related issues (natural kinds, properties, dispositions, counterfactuals . .). But more generally, Cartwright has a metaphysical Big Picture that emerges with increasing clarity, becoming explicit in DW. She does not make her chief objective that of defending this big-picture view overtly. Instead, she points out how it emerges from her studies of sci- ence as a natural and largely overlooked alternative to the more traditional Humean/empiricist and Rationalist big-pictures. The name of this alterna- tive view is, of course, the “Dappled World”. Cartwright is no theist of course, but it is nevertheless correct to say that for her, God is an Englishman rather than a Frenchman. This means that the world is more than a bit untidy and poorly organized; it has superficial rules rather than deep, necessary principles. Another useful contrast is this: Cartwright is more Aristotelian than Platonist. Universal, eternal forms, if they exist, are certainly no use to us in accounting for what actually happens in the world, whereas things’ natures and capacities certainly are.

  • Reason and Representation in Scientific Simulation
    Reason and Representation in Scientific Simulation Matthew Spencer | PhD Thesis Centre for Cultural Studies, Goldsmiths, University of London Declaration The work presented in this thesis is the candidate's own. - 2 - Abstract This thesis is a study of scientific practice in computational physics. It is based on an 18 month period of ethnographic research at the Imperial College Applied Modelling and Computation Group. Using a theoretical framework drawn from practice theory, science studies, and historical epistemology, I study how simulations are developed and used in science. Emphasising modelling as a process, I explore how software provides a distinctive kind of material for doing science on computers and how images and writings of various kinds are folded into the research process. Through concrete examples the thesis charts how projects are devised and evolve and how they draw together materials and technologies into semi-stable configurations that crystallise around the objects of their concern, what Hans-Jorg Rheinberger dubbed “epistemic things”. The main pivot of the research, however, is the connection of practice-theoretical science studies with the philosophy of Gaston Bachelard, whose concept of “phenomenotechnique” facilitates a rationalist reading of scientific practice. Rather than treating reason as a singular logic or method, or as a faculty of the mind, Bachelard points us towards processes of change within actual scientific research, a dynamic reason immanent to processes of skilled engagement. Combining this study of reason with the more recent attention to things within research from materialist and semiotic traditions, I also revive a new sense for the term “representation”, tracing the multiple relationships and shifting identities and differences that are involved in representing.

McGuire ii Copyright c by Zvi Biener 2008 iii The Unity of Science in Early-Modern Philosophy: Subalternation, Metaphysics and the Geometrical Manner in Scholasticism, Galileo and Descartes Zvi Biener, PhD University of Pittsburgh, 2008 The project of constructing a complete system of knowledge—a system capable of integrating all that is and could possibly be known—was common to many early-modern philosophers and was championed with particular alacrity by Ren´eDescartes. The inspiration for this project often came from mathematics in general and from geometry in particular: Just as propositions were ordered in a geometrical demonstration, the argument went, so should propositions be ordered in an overall system of knowledge. Science, it was thought, had to proceed more geometrico. I offer a new interpretation of ‘science more geometrico’ based on an analysis of the explanatory forms used in certain branches of geometry. These branches were optics, as- tronomy, and mechanics; the so-called subalternate, subordinate, or mixed-mathematical sciences.

  • Let's Not Talk About Objectivity
    Chapter 2 Let’s Not Talk About Objectivity Ian Hacking The first landmark event in twenty-first-century thinking about objectivity was, as is well known, Lorraine Daston and Peter Galison’s Objectivity (2007). It is a magisterial historical study of an epistemological concept, namely “objectivity”. Hence I call it a contribution to what I call (if it wants a name) meta-epistemology, although other prefer the less apt but better sounding historical epistemology. You will find more food for thought, not to mention headaches, in their book, than in any other body of work about objectivity. It will seem that Objectivity rejects the injunction stated in my title, for what is the book about, but objectivity? The authors are talking about objectivity if anyone is! Analytic philosopherslike myself make what others regard as too many distinctions, and I shall illustrate that here. Objectivity is about the concept of objectivity, its past uses, and the practices associated with it. For me, a concept is a word in its sites (Hacking 1984). In this context, that means the sites in which words cognate with “objective” were used over the past three centuries, the practices within which they were deployed, who had authority when using them, the actual modes of inscription, which in this case is closely associated with the use of pictures and other types of images. For me, as for a builder, a site is a rich field of activity to be described from many points of view, almost innumerable perspectives. Objectivity is a triumph of that type of analysis; it is not talking about objectivity but about the concept of objectivity (a distinction we most clearly owe to Gottlob Frege writing about number).

  • The Two Cultures” and the Historical Perspective on Science As a Culture Francesca Rochberg, Professor of History, University of California, Riverside
    Forum on Public Policy “The Two Cultures” and the Historical Perspective on Science as a Culture Francesca Rochberg, Professor of History, University of California, Riverside Abstract In the Rede lecture of 1959, C.P.Snow speaks in terms of two cultures, one of science, the other of literary intellectuals. Snow’s discussion presupposes that science represents a culture of its own, independent of and superior to the arts and humanities, and unified within itself. At our present distance from this claim, Snow’s point of view can be seen as a product of the philosophical orientation to science as an embodiment of universal truths about nature as well as cold war pressures on the West to improve educational standards in science. As the terms in which science is discussed have changed in the last nearly half-century, so has our response to the terms of Snow’s “Two Cultures”altered with time. The fields of history and sociology of science have shown the degree to which science is both fully enmeshed in society and conditioned by history, making it more difficult to support the idea of a separate “culture” of science immune from the effects of society and history. That the viability of a culture of science as an independent entity is contested in contemporary academic circles furthermore affects the mode in which students of science and the humanities are inculcated. This paper discusses the historical perspective on science as a culture and considers the impact of changing views about the nature, aims, and methods of science on the teaching of science and its history.

Description: Washington, DC: National Aeronautics and Space Administration, Office of Communications, NASA History Division, [2020] | Series: NASA history series ; sp-2020-4237 | Includes bibliographical references and index. | Summary: “Dr. Christopher Gainor’s Not Yet Imagined documents the history of NASA’s Hubble Space Telescope (HST) from launch in 1990 through 2020. This is considered a follow-on book to Robert W. Smith’s The Space Telescope: A Study of NASA, Science, Technology, and Politics, which recorded the development history of HST. Dr. Gainor’s book will be suitable for a general audience, while also being scholarly. Highly visible interactions among the general public, astronomers, engineers, govern- ment officials, and members of Congress about HST’s servicing missions by Space Shuttle crews is a central theme of this history book. Beyond the glare of public attention, the evolution of HST becoming a model of supranational cooperation amongst scientists is a second central theme. Third, the decision-making behind the changes in Hubble’s instrument packages on servicing missions is chronicled, along with HST’s contributions to our knowledge about our solar system, our galaxy, and our universe.

  • Establishing Commensurability: Intercalation, Global Meaning and the Unity of Science
    Establishing Commensurability: Intercalation, Global Meaning and the Unity of Science Alfred Nordmann University of South Carolina In the face of disuniªcation and incommensurability, how can the scientiªc community maintain itself and (re-)establish commensurability? According to Peter Galison’s investigations of twentieth-century microphysics, commen- surability is achieved through local coordination even in the absence of global meaning: The “strength and coherence” of science is due to diverse, yet coordi- nated action in trading zones between theorists and experimenters, experiment- ers and instrument builders, etc. Galison’s claim is confronted with Georg Christoph Lichtenberg’s establishment of commensurability between unitarians and dualists in the eighteenth century dispute about electrical ºuids. The contrast of cases suggests an alternative account: Commensurability may be established through the global coordination of local meaning. And where Galison reiªes the disuniªcation of science, this account suggests a dynamic interplay between de facto disuniªcation and an intended unity. This interplay is manifested in the pervasive and ongoing practical concern for the conditions of successful communication in a science that is constantly in-the-making. I In recent years, much of History, Philosophy, even Sociology of Science consisted in attempts to balance two competing historical intuitions: • Incommensurability arises as a matter of course from the under- determination of theories by the evidence, i.e., whenever even agreement on the facts allows for disagreements concerning the adoption or abandonment of a theory or research programme. To the extent that each research programme provides evaluative standards which inform judgements concerning its advance- ment, no research programme provides an internal standard for its abandonment or the surrender of those standards themselves.

  • Ten Problems in History and Philosophy of Science
    F O C U S Ten Problems in History and Philosophy of Science By Peter Galison* ABSTRACT In surveying the field of history and philosophy of science (HPS), it may be more useful just now to pose some key questions than it would be to lay out the sundry competing attempts to unify H and P. The ten problems this essay presents are grounded in a range of work of enormous interest—historical and philosophical work that has made use of productive categories of analysis: context, historicism, purity, and microhistory, to name but a few. What kind of account are we after—historically and philosophically—when we attempt to address science not as a vacuous generality but in its specific, local formation? N 8 AUGUST 1900, David Hilbert took the podium at the Sorbonne to address the O International Congress of Mathematicians. Rather than a presentation of the usual sort—summing up the speaker’s own work or conducting a high-altitude overview of the field—he presented ten problems from across the discipline’s map. While it would be foolish to belabor parallels between the history and philosophy of science (HPS) and mathematics, or between 2008 and 1900, or (worst of all) between this author and that one, perhaps this is a propitious moment to ask rather than tell. That odd conjunction, “HPS,” covers a multitude of sins, only some of which offer genuine temptation. True, some history of science in the 1930s through the 1950s aimed to use short historical accounts to bolster broad ambitions of a unification of scientific knowledge based on observation statements.
