Starting with some illustrative examples, I develop a systematic account of a specific type of experimentation--an experimentation which is not, as in the "standard view", driven by specific theories. It is typically practiced in periods in which no theory or--even more fundamentally--no conceptual framework is readily available. I call it exploratory experimentation and I explicate its systematic guidelines. From the historical examples I argue furthermore that exploratory experimentation may have an immense, but hitherto widely neglected, epistemic significance.

: The increasing attention on experiment in the last two decades has led to important insights into its material, cultural and social dimensions. However, the role of experiment as a tool for generating knowledge has been comparatively poorly studied. What questions are asked in experimental research? How are they treated and eventually resolved? And how do questions, epistemic situations, and experimental activity cohere and shape each other? In my paper, I treat these problems on the basis of detailed studies of (...) research practice. After presenting several cases from the history of electricity—Dufay, Ampère, and Faraday—I discuss a specific type of experiment—the "exploratory experiment"—and analyze how it works in concept formation. I argue that a fuller understanding of experiment can only be achieved by intertwining historical and philosophical perspectives in such a way that the very separation of the two become questioable.

This article examines the nineteenth-century debate about scientific method between John Stuart Mill and William Whewell. Contrary to standard interpretations (given, for example, by Achinstein, Buchdahl, Butts, and Laudan), I argue that their debate was not over whether to endorse an inductive methodology but rather over the nature of inductive reasoning in science and the types of conclusions yielded by it. Whewell endorses, while Mill rejects, a type of inductive reasoning in which inference is employed to find a property or (...) cause shared by the observed members of a class, which is generalized to all its members, including the unobserved ones. Because of this, Whewell’s inductivism, unlike Mill’s, is able to yield theoretical hypotheses referring to unob-servables such as molecules and light waves. This is contrary to the claims of some critics of inductivism who argue that inductivism is unable to yield such hypotheses. Moreover, I suggest that Whewell’s view of induction conforms more closely than Mill’s view to the practice of scientists such as Kepler, Newton, and Fresnel, who do attempt to discover laws involving unobservables.

In this paper I demonstrate that, contrary to the standard interpretations, William Whewell's view of scientific method is neither that of the hypothetico-deductivist nor that of the retroductivist. Rather, he offers a unique inductive methodology, which he calls "discoverers' induction." After explicating this methodology, I show that Kepler's discovery of his first law of planetary motion conforms to it, as Whewell claims it does. In explaining Whewell's famous phrase about "happy guesses" in science, I suggest that Whewell intended a distinction (...) between "inductions," which can be empirically verified, and "mere hypotheses"--or guesses--which cannot. Finally, I argue that Whewell's discoverers' induction is a view worthy of our attention today, because it avoids a number of problems faced by prominent alternative methodologies. (shrink)

This book consists of a collection of essays written between 1965 and 1981. Some have been published elsewhere; others appear here for the first time. Although dealing with different figures and different periods, they have a common theme: all are concerned with examining how the method of hy pothesis came to be the ruling orthodoxy in the philosophy of science and the quasi-official methodology of the scientific community. It might have been otherwise. Barely three centuries ago, hypothetico deduction was in (...) both disfavor and disarray. Numerous rival methods for scientific inquiry - including eliminative and enumerative induction, analogy and derivation from first principles - were widely touted. The method of hypothesis, known since antiquity, found few proponents between 1700 and 1850. During the last century, of course, that ordering has been inverted and - despite an almost universal acknowledgement of its weaknesses - the method of hypothesis (usually under such descriptions as 'hypothetico deduction' or 'conjectures and refutations') has become the orthodoxy of the 20th century. Behind the waxing and waning of the method of hypothesis, embedded within the vicissitudes of its fortunes, there is a fascinating story to be told. It is a story that forms an integral part of modern science and its philosophy. (shrink)

The aim of this work is to elucidate John F. W. Herschel’s distinctive contribution to nineteenth-century British inductivism by exploring his understanding of experimental methods. Drawing on both his explicit discussion of experiment in his Preliminary Discourse on Natural Philosophy and his published account of experiments he conducted in the domain of electromagnetism, I argue that the most basic principle underlying Herschel’s epistemology of experiment is that experiment enables a particular kind of lower-level experimental understanding of phenomena. Experimental practices provide (...) knowledge of a particular phenomenon as a genuine effect produced under precise material conditions whose connections with other phenomena can be traced by variations in experimental parameters. The orienting concern of experimental inquiry seems to be the production of a secure understanding of phenomena even if it has no direct theoretical significance. Insofar as one can generate this lower-level understanding, it can function both as a fertile source for explanatory principles about phenomena and as a body of evidence against which one can test the adequacy of an explanatory hypothesis. This project provides evidence of Herschel’s inductivism not merely as a philosophical approach to understanding the sciences but as a methodological commitment in scientific practice. (shrink)

This volume brings together eleven essays by the distinguished philosopher of science, Peter Achinstein. The unifying theme is the nature of the philosophical problems surrounding the postulation of unobservable entities such as light waves, molecules, and electrons. How, if at all, is it possible to confirm scientific hypotheses about "unobservables"? Achinstein examines this question as it arose in actual scientific practice in three nineteenth-century episodes: the debate between particle and wave theorists of light, Maxwell's kinetic theory of gases, and J.J. (...) Thomson's discovery of the electron. The book contains three parts, each devoted to one of these topics, beginning with an essay presenting the historical background of the episode and an introduction to the philosophical issues. There is an illuminating evaluation of various scientific methodologies, including hypothetico-deductivism, inductivism, and the method of independent warrant which combines features of the first two. Achinstein assesses the philosophical validity of both nineteenth-century and modern answers to questions about unobservables, and presents and defends his own solutions. (shrink)

The Victorian period in Britain was an “age of reform.” It is therefore not surprising that two of the era’s most eminent intellects described themselves as reformers. Both William Whewell and John Stuart Mill believed that by reforming philosophy—including the philosophy of science—they could effect social and political change. But their divergent visions of this societal transformation led to a sustained and spirited controversy that covered morality, politics, science, and economics. Situating their debate within the larger context of Victorian society (...) and its concerns, _Reforming Philosophy_ shows how two very different men captured the intellectual spirit of the day and engaged the attention of other scientists and philosophers, including the young Charles Darwin. Mill—philosopher, political economist, and Parliamentarian—remains a canonical author of Anglo-American philosophy, while Whewell—Anglican cleric, scientist, and educator—is now often overlooked, though in his day he was renowned as an authority on science. Placing their teachings in their proper intellectual, cultural, and argumentative spheres, Laura Snyder revises the standard views of these two important Victorian figures, showing that both men’s concerns remain relevant today. A philosophically and historically sensitive account of the engagement of the major protagonists of Victorian British philosophy, _Reforming Philosophy_ is the first book-length examination of the dispute between Mill and Whewell in its entirety. A rich and nuanced understanding of the intellectual spirit of Victorian Britain, it will be welcomed by philosophers and historians of science, scholars of Victorian studies, and students of the history of philosophy and political economy.

Historians of science have long been intrigued by the impact of disparate cultural styles on the science of a given country and time period. Richard Olson’s book is a case study in the interaction between philosophy and science as well as an examination of a particular scientific movement. The author investigates the methodological arguments of the Common Sense philosophers Thomas Reid, Dugald Stewart, Thomas Brown, and William Hamilton and the possible transmission of their ideas to scientists from John Playfair to (...) James Clerk Maxwell. His findings point out the need for modifications to the Duhem-Poincaré interpretation of British scientific style and the reassessment of the extent of Kantian influence on British physics. Originally published in 1975. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These paperback editions preserve the original texts of these important books while presenting them in durable paperback editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

... the topic of 'meaning' is the one topic discussed in philosophy in which there is literally nothing but 'theory' - literally nothing that can be labelled or even ridiculed as the 'common sense view'. Putnam, 'The Meaning of Meaning' This book explores some truths behind the truism that experimentation is a hallmark of scientific activity. Scientists' descriptions of nature result from two sorts of encounter: they interact with each other and with nature. Philosophy of science has, by and large, (...) failed to give an account of either sort of interaction. Philosophers typically imagine that scientists observe, theorize and experiment in order to produce general knowledge of natural laws, knowledge which can be applied to generate new theories and technologies. This view bifurcates the scientist's world into an empirical world of pre-articulate experience and know how and another world of talk, thought and argument. Most received philosophies of science focus so exclusively on the literary world of representations that they cannot begin to address the philosophical problems arising from the interaction of these worlds: empirical access as a source of knowledge, meaning and reference, and of course, realism. This has placed the epistemological burden entirely on the predictive role of experiment because, it is argued, testing predictions is all that could show that scientists' theorizing is constrained by nature. Here a purely literary approach contributes to its own demise. The epistemological significance of experiment turns out to be a theoretical matter: cruciality depends on argument, not experiment.

Reviews the epistemological ideas that inspired the classical economists: themethodological principles of Bacon, Descartes, Hobbes, Newton, Locke, Hume, Stewart, Herschel, andWhewell.

Originally published in 1830, this book can be called the first modern work in the philosophy of science, covering an extraordinary range of philosophical, methodological, and scientific subjects. "Herschel's book . . . brilliantly analyzes both the history and nature of science."—Keith Stewart Thomson, American Scientist.

John Herschel's natural philosophy, as summarized in his Preliminary Discourse on the Study of Natural Philosophy , has long been considered a continuation of Francis Bacon's New Organon; commentators have frequently interpreted both as promoting a naive, inductivist methodology. I argue rather that Herschel promotes a more warranted and more sophisticated account. A careful reading of the Discourse, as well as of his more specialized essays, shows instead that Herschel explicitly encourages and defends the use of hypothetical reasoning. Such a (...) methodology also describes his own extensive investigations that range over much of the spectrum of the physical sciences in the early nineteenth century. In developing this methodology, Herschel also drew on textual resources of Bacon, Isaac Newton, Roger Boscovich, Dugald Stewart, and others; most importantly, he was especially indebted to the investigations, views, and methods of his astronomer father, William Herschel. In particular, John Herschel applied his synthesis of these ideas to the empirical confirmation of his father's wide-ranging and speculative theories. In both the Discourse and in his other works, such as the Treatise on Astronomy, John Herschel promotes the use of hypotheses and of deductive methods as the tools used by experts, portraying inductive methods as the means by which sciences begin or as the most appropriate approach employed by amateurs. I also show how events of his life, including the socio-political context of early-nineteenth-century Britain, shaped Herschel's expression of his natural philosophy. Herschel's central role in the rise of science and of the philosophy of science in the nineteenth century make it imperative that we obtain a more accurate understanding of the doctrines he disseminated to practitioners of science and to popular audiences of the Victorian era. This volume provides the beginning of this broader task. (shrink)

Faraday's view of the mutual relation of speculative theories and laws of nature implies that there should be a procedure, leading from speculative considerations to a system of facts and laws in which theories do no longer play any role. In order to make out the degree in which Faraday's claims correspond to his practice, the way in which he gains an explanation of Arago's effect is analyzed. The thesis is proposed that he indeed has a procedure of leaving theories (...) aside. It is intimately connected with certain methodological guidelines of his experimentation. (shrink)
