The paper presents a realist account of the epistemic objectivity of science. Epistemic objectivity is distinguished from ontological objectivity and the objectivity of truth. As background, T.S. Kuhn’s idea that scientific theory-choice is based on shared scientific values with a role for both objective and subjective factors is discussed. Kuhn’s values are epistemologically ungrounded, hence provide a minimal sense of objectivity. A robust account of epistemic objectivity on which methodological norms are reliable means of arriving at the truth is presented. (...) The problem remains that deliberative judgement is required to determine the relevance and relative significance of a range of methodological norms. A role is sketched for cognitive virtues which may be exercised in the course of the deliberative judgement. (shrink)

The contemporary debate between scientific realism and anti-realism is conditioned by a polarity between two opposing arguments: the realist’s success argument and the anti-realist’s pessimistic induction. This polarity has skewed the debate away from the problem that lies at the source of the debate. From a realist point of view, the historical approach to the philosophy of science which came to the fore in the 1960s gave rise to an unsatisfactory conception of scientific progress. One of the main motivations for (...) the scientific realist appeal to the success of science was the need to provide a substantive account of the progress of science as an increase of knowledge about the same entities as those referred to by earlier theories in the history of science. But the idea that a substantive conception of progress requires continuity of reference has faded from the contemporary debate. In this paper, I revisit the historical movement in the philosophy of science in an attempt to resuscitate the original agenda of the debate about scientific realism. I also briefly outline the way in which the realist should employ the theory of reference as the basis for a robust account of scientific progress which will satisfy realist requirements. (shrink)

Scientific realism is the position that the aim of science is to advance on truth and increase knowledge about observable and unobservable aspects of the mind-independent world which we inhabit. This book articulates and defends that position. In presenting a clear formulation and addressing the major arguments for scientific realism Sankey appeals to philosophers beyond the community of, typically Anglo-American, analytic philosophers of science to appreciate and understand the doctrine. The book emphasizes the epistemological aspects of scientific realism and contains (...) an original solution to the problem of induction that rests on an appeal to the principle of uniformity of nature. (shrink)

This reply provides further grounds to doubt Mizrahi’s argument for an infallibilist theory of knowledge. It is pointed out that the fact that knowledge requires both truth and justification does not entail that the level of justification required for knowledge be sufficient to guarantee truth. In addition, an argument presented by Mizrahi appears to equivocate with respect to the interpretation of the phrase “p cannot be false”.

The notion of objectivity is ambiguous. A distinction is made between three primary notions of objectivity: ontological objectivity, the objectivity of truth and epistemic objectivity. It is suggested that a realist may explain the relationship between the three notions by saying that use of epistemically objective methods stands the best chance of leading to the objective truth about the objective world.

It is argued that to believe is to believe true. That is, when one believes a proposition one thereby believes the proposition to be true. This is a point about what it is to believe rather than about the aim of belief or the standard of correctness for belief. The point that to believe is to believe true appears to be an analytic truth about the concept of belief. It also appears to be essential to the state of belief that (...) to believe is to believe true. This is not just a contingent fact about our ordinary psychology, since even a non-ordinary believer must believe a proposition that they believe to be true. Nor is the idea that one may accept a theory as empirically adequate rather than as true a counter-example, since such acceptance combines belief in the truth of the observational claims of a theory with suspension of belief with respect to the non-observational claims of a theory. Nor is the fact that to believe is to believe true to be explained in terms of an inference governed by the T-scheme from the belief that P to the belief that P is true, since there is no inference from the former to the latter. To believe that P just is to believe that P is true. (shrink)

Does science provide knowledge of reality? In this paper, I offer a positive response to this question. I reject the anti-realist claim that we are unable to acquire knowledge of reality in favour of the realist view that science yields knowledge of the external world. But what world is that? Some argue that science leads to the overthrow of our commonsense view of the world. Common sense is “stone-age metaphysics” to be rejected as the false theory of our primitive ancestors. (...) Against such eliminativists about common sense, I argue that science both preserves and explains commonsense experience of the world. Though science may lead to the overthrow of deeply held beliefs, common sense reflects a more basic and durable level of experience. Commonsense beliefs are well-confirmed beliefs which are vindicated by their role in successful practical action each and every day. Common sense provides a firm basis on which to establish the realist approach to science. (shrink)

This is a survey of theories of scientific method which opens the book "After Popper, Kuhn and Feyerabend: Recent Issues in Theories of Scientific Method".

This is a comment on Moti Mizrahi's paper ' You Can't Handle the Truth: Knowledge = Epistemic Certainty'. Mizrahi claims that the factivity of knowledge entails that knowledge requires epistemic certainty. But the argument that Mizrahi presents does not proceed from factivity to certainty. Instead, it proceeds from a premise about the relationship between grounds and knowledge to the conclusion about certainty.

This paper considers the relevance of the Duhem-Quine thesis in economics. In the introductory discussion which follows, the meaning of the thesis and a brief history of its development are detailed. The purpose of the paper is to discuss the effects of the thesis in four specific and diverse theories in economics, and to illustrate the dependence of testing the theories on a set of auxiliary hypotheses. A general taxonomy of auxiliary hypotheses is provided to demonstrate the confounding of auxiliary (...) hypotheses with the testing of economic theory. (shrink)

Relativism in the philosophy of science is widely associated with the work of Thomas Kuhn and Paul Feyerabend. Kuhn and Feyerabend espoused views about conceptual change and variation of scientific method that have apparent relativistic implications. Both held that scientific theories or paradigms may be incommensurable due to semantic variation. Two ways that truth may be relative because of semantic incommensurability will be distinguished. Davidson’s criticism of the idea of an untranslatable language will be discussed, as well as a response (...) to incommensurability based on the causal theory of reference of Kripke and Putnam. A form of relativism with respect to epistemic rationality may also be derived from the claims of Kuhn and Feyerabend about methodological variation. Kuhn’s initial suggestions about paradigm-dependent standards and absence of extra-paradigmatic standards give rise to a view on which rationality is relative to paradigm. Kuhn’s later view that there is a stable set of shared scientific values is less prone to relativistic interpretation. Feyerabend’s claim that “anything goes” suggests an extreme form of relativism, but should be understood instead as the view that all rules of method may be violated in some circumstances. The latter brings Feyerabend’s view into line with Kuhn’s later view. (shrink)

This is a reply to Alex Grzankowski’s comment on my paper, ‘To Believe is to Believe True’. I argue that one may believe a proposition to be true without possessing the concept of truth. I note that to believe the proposition P to be true is not the same as to believe the proposition ‘P is true’. This avoids the regress highlighted by Grzankowski in which the concept of truth is employed an infinite number of times in a single belief.

This paper describes the position of scientific realism and presents the basic lines of argument for the position. Simply put, scientific realism is the view that the aim of science is knowledge of the truth about observable and unobservable aspects of a mind-independent, objective reality. Scientific realism is supported by several distinct lines of argument. It derives from a non-anthropocentric conception of our place in the natural world, and it is grounded in the epistemology and metaphysics of common sense. Further, (...) the success of science entitles us to infer both the approximate truth of mature scientific theories and the truth-conduciveness of the methods of science. (shrink)

This is a book review of Bojana Mladenovic, Kuhn's Legacy: Epistemology, Metaphilosophy, and Pragmatism .

The incommensurability thesis is the thesis that the content of some alternative scientific theories is incomparable due to translation failure between the vocabulary the theories employ. This paper presents an overview of the main issues which have arisen in the debate about incommensurability. It also briefly outlines a response to the thesis based on a modified causal theory of reference which allows change of reference subsequent to initial baptism, as well as a role to description in the determination of reference. (...) On such a view. the content of theories may be compared on the basis of shared reference, despite failure of translation. Two recent developments involving the incomnensurability thesis are also examined: (i) the taxonomic version of the incomensurability thesis found in Kuhn’s later writings. (ii) Hoyningen-Huenc’s neo-Kantian interpretation of Kuhn’s metaphysics. (shrink)

Les tables, les chaises, les gens assis sur des chaises, à des tables sont des objets composés de matière. Selon la science, la matière se compose principalement d'atomes. Les atomes sont faits d'électrons, de neutrons et de protons. Les neutrons et les protons forment un noyau autour duquel orbitent les électrons. Outre ces particules, les physiciens en ont découvert un grand nombre d'autres, comme les photons, les quarks et les neutrinos.

It is argued that in the absence of an algorithm of theory-choice, a role must be played by deliberative judgement in the process of choosing rationally between theories.

This is an introductory overview of theories of scientific method.

There are two chief tasks which confront the philosophy of scientific method. The first task is to specify the methodology which serves as the objective ground for scientific theory appraisal and acceptance. The second task is to explain how application of this methodology leads to advance toward the aim(s) of science. In other words, the goal of the theory of method is to provide an integrated explanation of both rational scientific theory choice and scientific progress.

The paper explores the relativistic implications of the thesis of incommensurability. A semantic form of incommensurability due to semantic variation between theories is distinguished from a methodological form due to variation in methodological standards between theories. Two responses to the thesis of semantic incommensurability are dealt with: the first challenges the idea of untranslatability to which semantic incommensurability gives rise; the second holds that relations of referential continuity eliminate semantic incommensurability. It is then argued that methodological incommensurability poses little risk (...) to the rationality or objectivity of science. For rational theory choice need neither be dictated by an algorithm nor governed by a binding set of rules. The upshot of the discussion is deflationary. There is little prospect for a relativistic conception of science based on inflated claims about the incommensurability of scientific theories. (shrink)

The aim of this chapter is to explore the relationship between Kuhn’s views about science and scientific realism. I present an overview of key features of Kuhn’s model of scientific change. The model suggests a relativistic approach to the methods of science. I bring out a conflict between this relativistic approach and a realist approach to the norms of method. I next consider the question of progress and truth. Kuhn’s model is a problem-solving model that proceeds by way of puzzles (...) and anomalies rather than progress toward truth. I explore Kuhn’s views about scientific progress in connection with scientific realist views about truth and progress. This leads to consideration of Kuhn’s views about the incommensurability of paradigms, as well as brief consideration of an anti-realist interpretation of his talk of world-change. I conclude by indicating that the scientific realist may endorse some aspects of Kuhn’s view. (shrink)

This paper considers the relationship between science and common sense. It takes as its point of departure, Eddington’s distinction between the table of physics and the table of common sense, as well as Eddington’s suggestion that science shows common sense to be false. Against the suggestion that science shows common sense to be false, it is argued that there is a form of common sense, basic common sense, which is not typically overthrown by scientific research. Such basic common sense is (...) strongly confirmed by our everyday experience and may itself serve as the basic for scientific realism. (shrink)

The paper discusses the version of entity realism presented by Ian Hacking in his book, Representing and Intervening. Hacking holds that an ontological form of scientific realism, entity realism, may be defended on the basis of experimental practices which involve the manipulation of unobservable entities. There is much to be said in favour of the entity realist position that Hacking defends, especially the pragmatist orientation of his approach to realism. But there are problems with the position. The paper explores two (...) issues that reflect negatively on Hacking’s version of the entity realist position. The first issue relates to the role of description in fixing the reference of theoretical terms. The second issue relates to Hacking’s claim that the argument for entity realism based on experiment is a different kind of argument from the standard argument for scientific realism based on the success of science. (shrink)

In this paper, I explore the purported conflict between science and common sense within the context of scientific realism. I argue for a version of scientific realism which retains commitment to realism about common sense rather than seeking to eliminate it.

As is well known, Putnam changed his philosophical position on a number of occasions throughout his career. In this paper, I reconsider the position of internal realism which Putnam defended from the mid-1970’s until around 1990. The paper opens with a discussion of the position that Putnam called “metaphysical realism”, since his internal realism emerged out of a critique of that position. The paper then briefly presents the internal realist view as one which involves an epistemic conception of truth, as (...) well as an anti-realist metaphysical outlook on which objects depend on conceptual scheme. The paper then provides a survey of the key objections to internal realism which emerged in the ensuing debate with defenders of realism. The paper concludes with a brief consideration of the relevance of Putnam’s later adoption of a direct realist theory of perception with respect to the issue of realism. (shrink)

The paper takes off from the suggestion of Jouni-Matti Kuukkanen that Kuhn’s account of science may be understood in coherentist terms. There are coherentist themes in Kuhn’s philosophy of science. But one crucial element is lacking. Kuhn does not deny the existence of basic beliefs which have a non-doxastic source of justification. Nor does he assert that epistemic justification only derives from inferential relationships between non-basic beliefs. Despite this, the coherentist interpretation is promising and I develop it further in this (...) paper. I raise the question of whether Kuhn’s account of science can deal with the input objection to coherentism. I argue that the role played by problems in Kuhn’s theory of science ensures that there is input from the external world into scientists’ belief-systems. I follow Hoyningen-Huene in pointing to the causal role played by the external world in determining perceptual states. I next turn to the question of whether Kuhn’s rejection of foundationalism implies coherentism. I argue that Kuhn’s rejection of the one-to-one relation between object and experience is compatible with a foundationalist account of justification. Nor does Kuhn’s rejection of the given entail the same coherentist implications as Sellars’ critique of the myth of the given. (shrink)

In this paper, I explore the relationship between the subject and the object from the perspective of scientific realism.

In ‘Induction and Natural Kinds’, I proposed a solution to the problem of induction according to which our use of inductive inference is reliable because it is grounded in the natural kind structure of the world. When we infer that unobserved members of a kind will have the same properties as observed members of the kind, we are right because all members of the kind possess the same essential properties. The claim that the existence of natural kinds is what grounds (...) reliable use of induction is based on an inference to the best explanation of the success of our inductive practices. As such, the argument for the existence of natural kinds employs a form of ampliative inference. But induction is likewise a form of ampliative inference. Given both of these facts, my account of the reliability of induction is subject to the objection that it provides a circular justification of induction, since it employs an ampliative inference to justify an ampliative inference. In this paper, I respond to the objection of circularity by arguing that what justifies induction is not the inference to the best explanation of its reliability. The ground of induction is the natural kinds themselves. (shrink)

In this paper, I provide an interpretation of ontological aspects of Kuhn's theory of science.

This paper presents a particularist and naturalist response to epistemic relativism. The response is based on an analysis of the source of epistemic relativism, according to which epistemic relativism is closely related to Pyrrhonian scepticism. The paper starts with a characterization of epistemic relativism. Such relativism is explicitly distinguished from epistemological contextualism. Next the paper presents an argument for epistemic relativism that is based on the Pyrrhonian problem of the criterion. It then considers a response to the problem of the (...) criterion proposed by Roderick Chisholm, which is based on epistemological particularism. After sketching Chisholm’s approach, a response to epistemic relativism is presented which combines Chisholm’s particularism with epistemic naturalism and reliabilism. A number of objections to the position are then considered. The paper ends with remarks about the relationship between particularism and the naturalistic response proposed to epistemic relativism.

This is a co-authored dialogue which explores epistemological and metaphysical questions raised by a social constructivist approach to science.

This paper addresses the relationship between the history and philosophy of science by way of the issue of epistemic normativity. After brief discussion of the relationship between history and philosophy of science in Kuhn’s own thinking, the paper focuses on the implications of the history of science for epistemic normativity. There may be historical evidence for change of scientific methodology, which may seem to support a position of epistemic relativism. However, the fact that the methods of science undergo variation does (...) not entail that epistemic justification varies with the methods employed by scientists. In order to arrive at the relativist conclusion, an epistemological argument is required that justification depends upon operative methods. This raises the question of epistemic normativity. Kuhn himself attempted to deal with this question on a number of occasions, but without success. Following brief discussion of Kuhn on this topic, the paper then turns to the treatment of epistemic normativity in the work of Lakatos, Laudan and Worrall. Lakatos and Laudan proposed that particular episodes from the history of science might be employed to adjudicate between alternative theories of method. Such episodes are selected on the basis of value judgements or pre-analytic intuitions, but such value judgements and intuitions are themselves problematic. Laudan later proposed the normative naturalist view that a rule of method is to be evaluated empirically on the basis of its reliability in conducing to a desired cognitive aim. Against this attempt to naturalize meta-methodology, Worrall argued that the normative force of the appeal to past reliability requires an a priori inductive principle. In my view, the problem of epistemic normativity is solved by combining the particularist focus on specific episodes in the history of science with the naturalistic account of the reliability of method.

The paper briefly reviews the main formulations of the incommensurability thesis by Feyerabend and Kuhn, as well as the main criticisms leveled against it. The question is then raised of whether there is a "phenomenon" of incommensurability that has been "discovered". It is argued that there is no such phenomenon.

This is a short introductory discussion of the idea of incommensurability as it is used in the philosophy of science.

In previous work, I have sought to show that the basic argument for epistemic relativism derives from the problem of the criterion that stems from ancient Pyrrhonian scepticism. Because epistemic relativism depends upon a sceptical strategy, it is possible to respond to relativism on the basis of an anti-sceptical strategy. I argue that the particularist response to scepticism proposed by Roderick Chisholm may be combined with a naturalistic and reliabilist conception of epistemic warrant as the basis for a satisfactory response (...) to epistemic relativism. In this paper, I outline this particularist response to relativism, and provide further commentary on the relationship between naturalism and particularism. In addition, I set the approach in contrast with reflective equilibrium approaches in epistemology. I also briefly explore the connection between the particularist response to relativism and G. E. Moore’s defense of an external world. (shrink)

The problem of rational theory-choice is the problem of whether choice of theory by a scientist may be objectively rational in the absence of an invariant scientific method. In this paper I offer a solution to the problem, but the solution I propose may come as something of a surprise. For I wish to argue that the work of the very authors who have put the rationality of such choice in question, Thomas Kuhn and Paul Feyerabend, contains all that is (...) needed to solve the problem.

This is an introduction to the position of scientific realism, which outlines a number of core doctrines of scientific realism, and indicates a number of optional and non-core doctrine. It also sketches the basic argument for scientific realism, known as the success argument.

This note poses a dilemma for scientific realism which stems from the apparent conflict between science and common sense. On the one hand, we may accept scientific realism and agree that there is a conflict between science and common sense. If we do this, we remove the evidential basis for science and have no reason to accept science in the first place. On the other hand, we may accept scientific realism and endorse common sense. If we do this, we must (...) reject the conflict between science and common sense. The dilemma is to be resolved by distinguishing between basic common sense and widely held beliefs. Basic common sense survives the advance of science and may serve as the evidential basis for science. (shrink)

Opening remarks delivered at "Incommensurability (and related matters)" conference, Hanover, June 1999.

What is the relation between method and truth? Are we justified in accepting a theory that satisfies the rules of scientific method as true? Such questions divide realism from anti-realism in the philosophy of science. Scientific realists take the methods of science to promote the realist aim of correspondence truth. Anti-realists either claim that the methods of science promote lesser epistemic goals than realist truth, or else they reject the realist conception of truth altogether. In this paper, I propose a (...) realist theory of the relation between method and truth. The theory consists of three basic elements: (a) a naturalistic treatment of epistemic normativity, (b) an instrumentalist conception of the nature of methodological rules, and (c) an abductive argument for the truth-conduciveness of the rules of scientific method.

This is a sequel to my paper, ‘What is Scientific Realism?’, which appeared in an earlier issue of this journal (Sankey, 2000a). A number of papers by other authors on topics relating to scientific realism have followed in subsequent issues. In this paper I revisit some of the themes developed in my earlier paper in the light of these later papers. I begin by restating the key ideas of the earlier paper. Next, I mention a number of afterthoughts which I (...) have had since the appearance of the paper. I then offer some comments on three of these subsequent papers. I hope these comments advance the discussion by clarifying and developing a number of key points. (shrink)

Cet article esquisse une réponse particulariste et naturaliste au relativisme épistémique. La réponse est basée sur une analyse spécifique de la source de relativisme épistémique. Selon cette analyse, le relativisme épistémique doit être considérée en lien proche avec le scepticisme pyrrhonien, car le relativisme est basée sur le problème du critère qui a été propose par les ces anciens sceptiques. L’article commence avec une caractérisation du relativisme épistémique. Puis il présente un argument pour le relativisme épistémique sur la base du (...) problème du critère. La réponse au problème du critère proposée par Roderick Chisholm est ensuite considérée. La réponse de Chisholm est fondée sur un particularisme épistémique. Apres avoir présenté l’approche de Chisholm, l’article propose une réponse au relativisme épistémique qui combine le particularisme de Chisholm avec une approche naturaliste et fiabiliste aux questions épistémiques. Quelques remarques à propos du lien entre Chisholm et la réponse proposée au relativisme épistémique sont aussi offertes. (shrink)
