The use of multiple means of determination to “triangulate” on the existence and character of a common phenomenon, object, or result has had a long tradition in science but has seldom been a matter of primary focus. As with many traditions, it is traceable to Aristotle, who valued having multiple explanations of a phenomenon, and it may also be involved in his distinction between special objects of sense and common sensibles. It is implicit though not emphasized in the distinction between (...) primary and secondary qualities from Galileo onward. It is arguably one of several conceptions involved in Whewell’s method of the “consilience of inductions” (Laudan 1971) and is to be found in several places in Peirce. (From M. Brewer and B. Collins, eds., (1981); Scientific Inquiry in the Social Sciences (a festschrift for Donald T. Campbell), San Francisco: Jossey-Bass, pp. 123–162.). (shrink)

Laudan constructs a fresh approach to a longtime problem for the philosopher of science: how to explain the simultaneous and widespread presence of both agreement and disagreement in science. Laudan critiques the logical empiricists and the post-positivists as he stresses the need for centrality and values and the interdependence of values, methods, and facts as prerequisites to solving the problems of consensus and dissent in science.

This essay contains a partial exploration of some key concepts associated with the epistemology of realist philosophies of science. It shows that neither reference nor approximate truth will do the explanatory jobs that realists expect of them. Equally, several widely-held realist theses about the nature of inter-theoretic relations and scientific progress are scrutinized and found wanting. Finally, it is argued that the history of science, far from confirming scientific realism, decisively confutes several extant versions of avowedly 'naturalistic' forms of scientific (...) realism.

By targeting and critiquing these assumptions, he lays the groundwork for a post-positivist philosophy of science that does not provide aid and comfort to the enemies of reason. This book consists of thirteen essays.

Intuitionistic meta-methodologies, which abound in recent philosophy of science, take the criterion of success for theories of scientific rationality to be whether those theories adequately explicate our intuitive judgments of rationality in exemplary cases. Garber's (1985) critique of Laudan's (1977) intuitionistic meta-methodology, correct as far as it goes, does not go far enough. Indeed, Garber himself advocates a form of intuitionistic meta-methodology; he merely denies any special role for historical (as opposed to contemporary or imaginary) test cases. What all (...) such positions lack is a base from which to inform, criticize, or restructure our core methodological intuitions. To acquiesce in this is to deny that exemplary cases can serve the sort of warranting role required for intuitionism. This point is reinforced by a series of reasons for denying the warranting role of pre-analytic judgments of rationality. These reasons point the way toward an improved approach to meta-methodology.

For more than a half-century, evidence scholars have been exploring whether the criminal standard of proof can be grounded in decision theory. Such grounding would require the emergence of a social consensus about the utilities to be assigned to the four outcomes at trial. Significant disagreement remains, even among legal scholars, about the relative desirability of those outcomes and even about the formalisms for manipulating their respective utilities. We attempt to diagnose the principal reasons for this dissensus and to suggest (...) ways in which a broadly shared evaluation might be forged, both with respect to the appropriate equations for defining the standard of proof and with respect to the appropriate utilities to associate with the various trial outcomes. Where consensus cannot be forged, we hold that remaining differences can probably be finessed. We also suggest ways to elicit the utilities of individuals on these matters so as to avoid the usual flaws of such surveys. Along the way, we note a). the disproportionate role that the Blackstone ratio of errors continues to play in appraisals of the utilities of trial outcomes (despite its unintelligibility in the context of utilities) and b). the persisting belief -for which there is no theoretical basis-that every plausible assignment of utilities will inevitably result in a very high standard of proof. Finally, we examine some of the technical features associated with a proposed rank ordering of the utilities of trial outcomes. (shrink)

"A rich historical pastiche of 17th- and 18th-century philosophy, science, and religion."—G. Y. Craig, New Scientist "This book, by a distinguished Italian historian of philosophy, is a worthy successor to the author's important works on Francis Bacon and on technology and the arts. First published in Italian (in 1979), it now makes available to English readers some subtly wrought arguments about the ways in which geology and anthropology challenged biblical chronology and forced changes in the philosophy of history in the (...) early modern era.... [Rossi] shows that the search for new answers about human origins spanned many disciplines and involved many fascinating intellects—Bacon, Bayle, Buffon, Burnet, Descartes, Hobbes, Holbach, Hooke, Hume, Hutton, Leibniz, de Maillet, Newton, Pufendorf, Spinoza, Toland, and, most especially, Vico, whose works are impressively and freshly reevaluated here."—Nina Gelbart, American Scientist.

One of the ironies of our time is the sparsity of useful analytic tools for understanding change and development within technology itself. For all the diatribes about the disastrous effects of technology on modern life, for all the equally uncritical paeans to technology as the panacea for human ills, the vociferous pro- and anti-technology movements have failed to illuminate the nature of technology. On a more scholarly level, in the midst of claims by Marxists and non-Marxists alike about the technological (...) underpinnings of the major social and economic changes of the last couple of centuries, and despite advice given to government and industry about managing science and technology by a small army of consultants and policy analysts, technology itself remains locked inside an impenetrable black box, a deus ex machina to be invoked when all other explanations of puzzling social and economic pheoomena fail. The discipline that has probably done most to penetrate that black box in recent years by studying the 1 internal development of technology is history. Historians of technology and certain economic historians have carried out careful and detailed studies on the genesis and impact of technological innovations, and the structu-re of the social systems associated with those innovations. Within the past few decades tentative consensus about the periodization and the major traditions within the history of technology has begun to emerge, at least as far as Britain and America in the eighteenth and nineteenth century are concerned.

This paper seeks to show that Achinstein's recent attempt to establish that both parties to the wave-particle debate in 19th-century optics were Bayesian conditionalizers forces us to ignore several of the key conceptual issues in that controversy-not least the role of the vera causa principle and, more important still, the role of positive evidence in securing acceptance for the wave theory of light.

This paper argues that it has been widely assumed by philosophers of science that the cumulative retention of explanatory success is a "sine qua non" for making judgements about the progress or rational preferability of one theory over another. It has also been assumed that it is impossible to make objective, Comparative judgements of the acceptability of rival theories unless all the statements of both theories could be translated into a common language. This paper seeks to show that both these (...) dogmas are mistaken; that progress without cumulativity and comparability without commensurability are both viable. (shrink)

Beginning with the premise that the principal function of a criminal trial is to find out the truth about a crime, Larry Laudan examines the rules of evidence and procedure that would be appropriate if the discovery of the truth were, as higher courts routinely claim, the overriding aim of the criminal justice system. Laudan mounts a systematic critique of existing rules and procedures that are obstacles to that quest. He also examines issues of error distribution by offering (...) the first integrated analysis of the various mechanisms - the standard of proof, the benefit of the doubt, the presumption of innocence and the burden of proof - for implementing society's view about the relative importance of the errors that can occur in a trial.

This paper surveys recent trends in the history of science, using quotations from works published in the last decade. It suggests that philosophers of science have not yet come to terms with those changes, indicates which might or might not lead to productive interchange, and concludes that history and philosophy of science are now further apart than at any time since the early 1960's.

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)

Normative naturalism is a view about the status of epistemology and philosophy of science; it is a meta-epistemology. It maintains that epistemology can both discharge its traditional normative role and nonetheless claim a sensitivity to empirical evidence. The first sections of this essay set out the central tenets of normative naturalism, both in its epistemic and its axiological dimensions; later sections respond to criticisms of that species of naturalism from Gerald Doppelt, Jarrett Leplin and Alex Rosenberg.
