In a 1993 paper, I argued that empirical treatments of the epistemologyused by scientists in experimental work are too abstract in practice tocounter relativist efforts to explain the outcome of scientificcontroversies by reference to sociological forces. This was because, atthe rarefied level at which the methodology of scientists is treated byphilosophers, multiple mutually inconsistent instantiations of theprinciples described by philosophers are employed by contestingscientists. These multiple construals change within a scientificcommunity over short time frames, and these different versions ofscientific methodology (...) can determine the outcome of a controversy. Iillustrated with a comparatively detailed analysis of the methodologyused by biologists debating the existence of an entity called thebacterial mesosome between the mid-1950s and the mid-1970s. This 1993piece has drawn several critiques in the philosophical literature. Inthis present piece I respond to these critiques and argue that they failto address the core argument of the original paper, and I reflectfurther on the methodologies of philosophers of science pursuingempirical or `naturalistic' epistemology.

Abstract The success of the pragmatic account of truth is often thought to founder on the principle of bivalence?the principle which holds that every genuine statement in the indicative mood is either true or false. For pragmatists must, it seems, claim that the principle does not hold for theoretical statements and observation statements about the past. That is, it seems that pragmatists must deny objective truth?values to these perfectly respectable sorts of hypotheses. In this paper, after examining three pragmatist attitudes (...) towards bivalence, I shall suggest that the pragmatist's proper stance is to treat bivalence as a regulative assumption of inquiry.

After delineating the distinguishing features of pragmatism, and noting the resources that pragmatists have available to respond effectively as pragmatists to the two major objections to pragmatism, I examine and critically evaluate the various proposals that pragmatists have offered as a solution to the problem of induction, followed by a discussion of the pragmatic positions on the status of theoretical entities. Thereafter I discuss the pragmatic posture toward the nature of explanation in science. I conclude that pragmatism has (a) a (...) generally compelling solution to Hume's problem of induction; (b) no specific position on the status of theoretical entities, although something like the non-realism of the sort developed by van Fraassen seems a defensible candidate for most pragmatists in general, even though there are non-trivial objections to van Fraassen's position; and (c) central to the pragmatic conception of scientific explanation is the abandonment of our common conception of truth as a necessary condition for sentences to provide adequate explanations, and a drift in the direction of a contextualist account of explanation.

The central terms of certain theories which were valued highly in the past, such as the phlogiston theory, are now believed by realists not to refer. Laudan and others have claimed that, in the light of the existence of such theories, scientific realism is untenable. This paper argues in response that realism is consistent with — and indeed is able to explain — such theories' having been highly valued and yet not being close to the truth. It follows that the (...) set of highly-valued past theories cited by Laudan, presumed to militate against realism, is in fact innocuous to the doctrine. The argument hinges largely on identifying the grounds on which theory-adoption is actually performed. (shrink)

RésuméJe me demande ici si les conceptions pragmatiques de la vérité peuvent être réconciliées avec les intuitions ordinaires quant à la portée de la bivalence. Je soutiens que les pragmatistes sont conduits à accepter une distinction du genre «type / occurrence» entre les formes d'une investigation et ses instanciations particulières, sous peine de banaliser leur vérificationnisme. Néanmoins, même la conception révisée que j'examine échoue à sauver les approches épistémiques de la vérité de certaines conséquences peu plausibles.

Abstract It is sometimes thought that Absolute Idealism was undermined by its inability to deal with science. Through a critical discussion of F. H. Bradley's philosophy of science, this idea is challenged. His views on science are divided into a positive and a negative part, and it is argued that, although he found the scientific world view to be essentially false, he was nonetheless able to develop a sympathetic and intelligent philosophy of science. This was basically pragmatic and instrumental in (...) tone, and gave to science a large measure of autonomy from philosophy. His doctrine is connected with certain contemporary ideas in the philosophy of science. (shrink)
