This paper presents a response to the question of the relationship between science and reality. It rejects 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, it is argued 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 paper is a response to an objection that Markus Seidel has made to my analysis of epistemic relativism. Seidel argues that the epistemic relativist is unable to base a relativist account of justification on the sceptical problem of the criterion in the way that I have suggested in earlier work. In response to Seidel, I distinguish between weak and strong justification, and argue that all the relativist needs is weak justification. In addition, I explain my reasons for employing the (...) idiom of objectivity rather than that of absolutism which Seidel prefers. -/- . (shrink)

This paper revisits one of the key ideas developed in The Structure of Scientific Revolutions. In particular, it explores the methodological form of incommensurability which may be found in the original edition of Structure. It is argued that such methodological incommensurability leads to a form of epistemic relativism. In later work, Kuhn moved away from the original idea of methodological incommensurability with his idea of a set of epistemic values that provides a basis for rational theory choice, but do not (...) constitute an algorithm for such choice. The paper also explores the sceptical basis for the epistemic relativism of the original view that Kuhn proposes in Structure. It suggests that the main sceptical rationale for such relativism may be avoided by a particularist and naturalist conception of epistemic normativity. When this approach is combined with the appeal to external methodological standards endorsed by the later Kuhn and his critics, the epistemic relativism of Structure may be completely repudiated.

This article is a book review of Anastasios Brenner's book Raison Scientifique et Valeurs Humaines.

While the phrase "metaphysics of science" has been used from time to time, it has only recently begun to denote a specific research area where metaphysics meets philosophy of science—and the sciences themselves. The essays in this volume demonstrate that metaphysics of science is an innovative field of research in its own right. The principal areas covered are: (1) The modal metaphysics of properties: What is the essential nature of natural properties? Are all properties essentially categorical? Are they all essentially (...) dispositions, or are some categorical and others dispositional? (2) Realism in mathematics and its relation to science: What does a naturalistic commitment of scientific realism tell us about our commitments to mathematical entities? Can this question be framed in something other than a Quinean philosophy? (3) Dispositions and their relation to causation: Can we generate an account of causation that takes dispositionality as fundamental? And if we take dispositions as fundamental (and hence not having a categorical causal basis), what is the ontological ground of dispositions? (4) Pandispositionalism: Could all properties be dispositional in nature? (5) Natural kinds: Are there natural kinds, and if so what account of their nature should we give? For example, do they have essences? Here we consider how these issues may be illuminated by considering examples from reals science, in particular biochemistry and neurobiology. (shrink)

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.

This article is a review of Paul Feyerabend's book, The Tyranny of Science.

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.

This article explores the relationship between epistemic relativism and Pyrrhonian scepticism. It is argued that a fundamental argument for contemporary epistemic relativism derives from the Pyrrhonian problem of the criterion. Pyrrhonian scepticism is compared and contrasted with Cartesian scepticism about the external world and Humean scepticism about induction. Epistemic relativism is characterized as relativism due to the variation of epistemic norms, and is contrasted with other forms of cognitive relativism, such as truth relativism, conceptual relativism and ontological relativism. An argument (...) from the Pyrrhonian problem of the criterion to epistemic relativism is presented, and is contrasted with three other arguments for epistemic relativism. It is argued that the argument from the criterion is the most fundamental argument for epistemic relativism. Finally, it is noted how the argument of the present paper fits with the author’s previous suggestion that a particularist response to the Pyrrhonian sceptic may be combined with a naturalistic view of epistemic warrant to meet the challenge of epistemic relativism.

This paper explores the relationship between scepticism and epistemic relativism in the context of recent history and philosophy of science. More specifically, it seeks to show that significant treatments of epistemic relativism by influential figures in the history and philosophy of science draw upon the Pyrrhonian problem of the criterion. The paper begins with a presentation of the problem of the criterion as it occurs in the work of Sextus Empiricus. It is then shown that significant treatments of epistemic relativism (...) in recent history and philosophy of science (critical rationalism, historical philosophy of science and the strong programme) draw upon the problem of the criterion. It is briefly suggested that a particularist response to the problem of the criterion may be put to good use against epistemic relativism. (shrink)

At stake in the classical realism-debate is the clash between realist and anti-realist positions. In recent years, the classical form of this debate has undergone a double transformation. On the one hand, the champions of realism began to pay more attention to the interpretative dimensions of scientific research. On the other hand, anti-realists of various sorts realized that the rejection of the hypostatization of a “reality out there” does not imply the denial of working out a philosophically adequate concept of (...) reality. Against the background of this double transformation, new arguments in the realism-debate emerged. The present Introduction is an attempt at systematizing these arguments within the spectrum of doctrines between the poles of scientific realism (exposed and defended by Howard Sankey) and hermeneutic realism (advocated by Dimitri Ginev). The authors try also to demonstrate that after the classical debates the issue of scientism has to be addressed in new ways. (shrink)

Some philosophers (e.g. Descartes) argue that there is an evidential relationship between language and thought, such that presence of language is indicative of mind. Recent language acquisition research with apes such as chimpanzees and bonobos attempts to demonstrate the capacity of these primates to acquire at least rudimentary linguistic capacity. This paper presents a case study of the ape language research and explores the consequences of the research with respect to the argument that animals lack mind because they fail to (...) display linguistic capacity.

This paper presents a naturalistic response to the challenge of epistemic relativism. The case of the Azande poison oracle is employed as an example of an alternative epistemic norm which may be used to justify beliefs about everyday occurrences. While a distinction is made between scepticism and relativism, an argument in support of epistemic relativism is presented that is based on the sceptical problem of the criterion. A response to the resulting relativistic position is then provided on the basis of (...) a particularist response to scepticism combined with a naturalistic approach to the warrant of epistemic norms. It is argued that it is possible to comparatively assess the ability of epistemic norms to lead to epistemic aims. As against the epistemic relativist, it is possible to provide an objective basis for the choice between alternative epistemic norms. (shrink)

In this response, doubts are expressed relating to the treatment by Hoyningen-Huene and Oberheim of the relation between incommensurability and content comparison. A realist response is presented to their treatment of ontological replacement. Further questions are raised about the coherence of the neo-Kantian idea of the world-in-itself as well as the phenomenal worlds hypothesis. The notion of common sense is clarified. Meta-incommensurability is dismissed as a rhetorical device which obstructs productive discussion.

This paper reviews the situation with respect to the referential approach to the problem of semantic incommensurability. It argues that the thesis of semantic incommensurability does not pose a significant threat to scientific realism. However, there exists a "non-realist" defence of incommensurability, according to which the referential approach begs the question against advocates of the incommensurability thesis. This defence is criticized, and the basis for a realist response to incommensurability is presented.

This paper examines the question of whether scientific realism is committed to the inevitability of science or is consistent with claims of the contingency of science. In order to address this question, a general characterization of the position of scientific realism is presented. It is then argued that scientific realism has no evident implications with regard to the inevitability of science. A historical case study is presented in which contingency plays a significant role, and the appropriate realist response to this (...) case study is indicated. Finally, it is argued that, when conjoined with a reliabilist theory of method, realism does have implications for the inevitability of science. (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.

The volume is a collection of essays devoted to the analysis of scientific change and stability. It explores the balance and tension that exist between commensurability and continuity on the one hand, and incommensurability and discontinuity on the other. Moreover, it discusses some central epistemological consequences regarding the nature of scientific progress, rationality and realism. In relation to these topics, it investigates a number of new avenues, and revisits some familiar issues, with a focus on the history and philosophy of (...) physics, and an emphasis on developments in cognitive sciences as well as on the claims of “new experimentalists”.The book constitutes fully revised versions of papers which were originally presented at the international colloquium held at the University of Nancy, France, in June 2004. Each paper is followed by a critical commentary. The conference was a striking example of the sort of genuine dialogue that can take place between philosophers of science, historians of science and scientists who come from different traditions and endorse opposing commitments. This is one of the attractions of the volume. (shrink)

Alan Musgrave is one of the foremost contemporary defenders of scientific realism. He is also one of the leading exponents of Karl Popper’s critical rationalist philosophy. In this paper, my main focus will be on Musgrave’s realism. However, I will emphasize epistemological aspects of realism. This will lead me to address aspects of his critical rationalism as well.

According to scientific realism, the aim of science is to discover the truth about both observable and unobservable aspects of the mind-independent, objective reality, which we inhabit. It has been objected by Putnam and others that such a metaphysically realist position presupposes a God’s Eye point of view, of which no coherent sense can be made. In this paper, I will argue for two claims. First, scientific realism does not require the adoption of a God’s Eye point of view. Instead, (...) scientific realism is a hypothesis about the relationship between scientific theory and reality which may be proposed from within our human perspective. Second, even if scientific realism did require a God’s Eye point of view, this would not necessarily be to the detriment of realism. For it is possible to develop an intelligible external perspective on human epistemic relations to our environing reality. (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.

But while it is evident that there is a close relation between method and rational justification, substantive questions remain about the relation between method and truth. For example, are scientists whom method licenses in accepting a theory or experimental result thereby licensed in accepting the theory or result as true? Does use of scientific method lead scientists to discover the truth about the world? Questions such as these are questions about the truth-conduciveness of method. While they relate directly to the (...) epistemic status of method, they bear indirectly on the nature of rational justification. For if use of method conduces to truth, then, given the relation between method and justification, the warrant provided by method is warrant with respect to truth. (shrink)

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)

Some think that issues to do with scientific method are last century's stale debate; Popper was an advocate of methodology, but Kuhn, Feyerabend, and others are alleged to have brought the debate about its status to an end. The papers in this volume show that issues in methodology are still very much alive. Some of the papers reinvestigate issues in the debate over methodology, while others set out new ways in which the debate has developed in the last decade. The (...) book will be of interest to philosophers and scientists alike in the reassessment it provides of earlier debates about method and current directions of research. (shrink)

This paper addresses the question of whether it is rational for scientists to pursue the realist aim of truth. The point of departure is a pair of objections to the aim of truth due to the anti-realist author, Larry Laudan: first, it is not rational to pursue an aim such as truth which we cannot know we have reached; second, truth is not a legitimate aim for science because it cannot be shown to be attained. Against Laudan, it is argued (...) not only that it is possible to achieve theoretical knowledge, but that we may have evidence of an indirect, fallible nature that the methods employed in science do indeed lead to the truth.

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 gives an overview of key themes of twentieth century philosophical treatment of the language of science, with special emphasis on the meaning variance of scientific terms and the comparison of alternative theories. These themes are dealt with via discussion of the topics of: (a) the logical positivist principle of verifiability and the problem of the meaning of theoretical terms, (b) the postpositivist thesis of semantic incommensurability, and (c) the scientific realist response to incommensurability based on the causal theory (...) of reference.

In a shift of position that has gone largely unnoticed by the great majority of commentators, Thomas Kuhn's version of the incommensurability thesis underwent a major transformation over the last decade and a half of his life. In his later work, Kuhn argued that incommensurability is a relation of translation failure between local subsets of interdefined theoretical terms, which encapsulate the taxonomic structure of a theory. Incommensurability arises because it is impossible to transfer the natural categories employed within one taxonomic (...) structure into the categorial system of another such structure. Apparently on the basis of such taxonomic incommensurability, Kuhn asserted a number of antirealist theses about truth, reference and reality. In this paper, it will be argued, however, that, far from leading to antirealist consequences about the relationship between theory and reality, the taxonomic incommensurability thesis may be incorporated unproblematically within a reasonably robust scientific realist framework.

The paper sketches an ontological solution to an epistemological problem in the philosophy of science. Taking the work of Hilary Kornblith and Brian Ellis as a point of departure, it presents a realist solution to the Humean problem of induction, which is based on a scientific essentialist interpretation of the principle of the uniformity of nature. More specifically, it is argued that use of inductive inference in science is rationally justified because of the existence of real, natural kinds of things, (...) which are characterized as such by the essential properties which all members of a kind necessarily possess in common. The proposed response to inductive scepticism combines the insights of epistemic naturalism with a metaphysical outlook that is due to scientific realism. (shrink)

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)

In a recent exchange, John Worrall and Larry Laudan have debated the merits of the model of rational scientific change proposed by Laudan in his book Science and Values. On the model advocated by Laudan, rational change may take place at the level of scientific theory and methodology, as well as at the level of the epistemic aims of science. Moreover, the rationality of a change which occurs at any one of these three levels may be dependent on considerations at (...) the remaining levels. Yet, in spite of the avowedly anti-relativistic motivation of Laudan's model, Worrall criticizes Laudan for irrevocably relativizing scientific rationality to historically variant methodological standards.

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.

Since 1962 Kuhn's concept of incommensurability has undergone a process of transformation. His current account of incommensurability has little in common with his original account of it. Originally, incommensurability was a relation of methodological, observational and conceptual disparity between paradigms. Later Kuhn restricted the notion to the semantical sphere and assimilated it to the indeterminacy of translation. Recently he has developed an account of it as localized translation failure between subsets of terms employed by theories.

In his early work Feyerabend argues that certain theories are incommensurable due to semantic variance. In this paper it is argued that Feyerabend relies on a description theory of reference in the course of his argument for incommensurability and in his analysis of the relevant kind of semantic variance. Against this it is objected that such reliance on the description theory eliminates ostensive reference determination and obscures the presence of theoretical conflict.
