This comprehensive volume marks a new standard in scholarship in the still emerging field of the philosophy of chemistry. With selections drawn from a wide range of scholarly disciplines, philosophers, chemists, and historians of science here converge to ask some of the most fundamental questions about the relationship between philosophy and chemistry. What can chemistry teach us about longstanding disputes in the philosophy of science over such issues as reductionism, autonomy, and supervenience? And what new issues may chemistry bring to (...) the forefront now that it has joined physics and biology as a serious topic for philosophical reflection? This newest addition to the prestigious Boston Studies in the Philosophy of Science series marks the true arrival of philosophy of chemistry within the corpus of the philosophy of science. (shrink)

The direct reading emission spectrometer was developed during the1940s. By substituting photo-multiplier tubes and electronics forphotographic film spectrograms, the interpretation of special lineswith a densitometer was avoided. Instead, the instrument providedthe desired information concerning percentage concentration ofelements of interest directly on a dial. Such instruments `de-skill' the job of making such measurements. They do this by encapsulatingin the instrument the skills previously employed by the analyst,by `skilling' the instrument. This paper presents a history of thedevelopment of the Dow Chemical/Baird Associates (...) direct reader. Thishistory is used to argue for a materialist conception of knowledge.The instrument is a material form of knowledge, knowledge of aspectsof spectroscopy, analytical spectrochemistry, electronics, instrumentdesign and construction, and metal production industry economics.

: According to Peter Galison (1997), science has a highly fractionated structure with multiple sub-sub-disciplines, each with its own agenda. Cooperative trading between groups is necessary for most scientific work to move forward, and it is this trading that preserves the stability of science. We argue that it is not trading per se, but trading in a gift (as opposed to a commodity) economy that guarantees stability. We support our claims with an examination of contemporary work on magnetic resonance imaging (...) instrumentation. Specifically, we consider: (1) How a feature improvement, intended to reduce scan time, led to substantial medical mis-diagnosis; (2) How a technical error, when corrected, created a consumer crisis in which radiologists preferred technically flawed instruments; (3) How new magnetic resonance theory radically altered the physical interpretation of MRI images; (4) How the MRI instrument at first was financially supported by, and--ironically--ultimately invalidated, the accepted understanding of the nature, source and management of chronic back pain. Ultimately there are three reasons stability requires gifting. First, without a general sense of shared purpose traders will not be committed to mutual engagement; profit does not provide an adequate shared purpose for the MRI community. Second, stability requires trust, and profits are not an adequate foundation for trust. Finally, knowledge is a gift that will not keep on giving if treated simply as a source of profit. (shrink)

Recently we have learned how experiment can have a life of its own. However, experiment remains epistemologically disadvantaged. Scientific knowledge must have a theoretical/propositional form. To begin to redress this situation, I discuss three ways in which instruments carry meaning: 1. Scientific instruments can carry tremendous loads of meaning through association, analogy and metaphor. 2. Instrumental models of complicated phenomena work representationally in much the same way as theories. 3. Instruments which create new phenomena establish a new field of material (...) possibilities. I suggest that scientists employ a "visual/physical/material logic," analogous to propositional logic, which establishes relations between different material forms. (shrink)

In this paper we elucidate a particular type of instrument. Striking-phenomenon instruments assume their striking profile against the shifting backdrop of theoretical uncertainties. While technologically stable, the phenomena produced by these instruments are linguistically fuzzy, subject to a variety of conceptual representations. But in virtue of their technological stability alone, they can provide a foundation for further technological as well as conceptual development. Sometimes, as in the case of the pulse glass, the phenomenon is taken to confirm conflicting theoretical views; (...) sometimes, as in the case of the Lichtenberg-figures, it holds out the false promise of crucial theoretical importance; sometimes, as in the case of the airpump in the 18th century, it emphatically short-circuits theory and human ingenuity, giving a voice to nature herself; and sometimes, finally, as in the case of the quincunx, the phenomenon stands in for theoretical accounts. We propose and develop the salient features of these instruments demonstrating their importance to our understanding of science. (shrink)

I present five theses to characterize and argue for "Instrumental Realism," a realism wedded to what we do with instruments, and not what our theories say: The Independence Thesis: Questions about realism are independent of questions about meaning. The Intervening Thesis: Our ability to produce consistent effects with our instruments provides one guarantee that we are engaged with the real world. The Historical Thesis: If the descriptions of what we know and do are of something real, then it will be (...) possible to trace a history from earlier antiquated names and actions to current usages. The Instruments-Do-Not-Always-Work-Right Thesis: Since instruments do not always work right, a successful instrumental intervention cannot be a social construct. The Tinkering Thesis: Since instruments are created by tinkering, we should not take any claim that generalizes away from our instrumental practice realistically. (shrink)

The rule of implication, (+) If hypothesis H implies hypothesis I, then evidence sufficient to warrant the rejection of I, in turn warrants the rejection of H, is a very plausible principle of inductive inference. It is shown that significance tests violate this principle. Two ways to account for this violation are considered; neither account is fully satisfactory. First, a distinction might be made between the absolute degree of confirmation and the change in the degree of confirmation due to a (...) specific result. Measures of the change in the degree of confirmation need not obey the rule of implication. Unfortunately, it is difficult to interpret significance tests as a measure of the change in degree of confirmation of an hypothesis. Second, it might be observed that hypotheses are sought that are informative as well as faithful to observations. Amalgamating a measure of informativeness with a measure of faithfulness can result in violations of the rule of implication. Unfortunately, it is unclear why significance tests amalgamating measures of informativeness and faithfulness are desirable. (shrink)

In a recent article Ian Hacking argues that there can be cases where no probabilities may correctly be ascribed to individual members of a population, while probabilities are correctly ascribable to the population as a whole. In this paper a simple artificial coin-flipping model for such probabilities, not 'grounded from below' is constructed. The inferences licensed by this model and a consequence of the model for the theory of statistical tests is explored.
