This book presents a critical analysis of the semantic incommensurability thesis of Thomas Kuhn and Paul Feyerabend. In putting forward the thesis of incommensurability, Kuhn and Feyerabend drew attention to complex issues concerning the phenomenon of conceptual change in science. They raised serious problems about the semantic and logical relations between the content of theories which deploy unlike systems of concepts. Yet few of the more extreme claims associated with incommensurability stand scrutiny. The argument of this book is as follows. (...) The terms of theories with different concepts diverge semantically and the vocabularies of such theories may not be fully intertranslatable. Given the possibility of referential overlap between the terms of conceptually divergent theories, it does not follow that the content of such theories is incomparable. Nor, given the distinction between understanding a language and translation from one language into another, does it follow that the proponents of mutually untranslatable theories are unable to communicate. Neither is it the case that the shift between conceptually divergent theories involves a discontinuous transition between theories which have no common reference or that refer to distinct worlds of their own making. The semantic differences resulting from conceptual variance may be embraced within a thoroughly realist framework on which they are construed as diverse linguistic relations to a fixed and independent reality. -/- The book, which was originally published in 1994, has now been re-issued in the Routledge Revivals series. -/- .

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.

This is a brief exploration of the notion of an objective fact. The form of objectivity at issue is distinct from epistemic objectivity or objectivity about truth. It is an ontological form of objectivity. Objective facts may obtain whether or not we know, believe or are aware of them. They depend upon objects, for example, on the properties that objects have or the relationships into which objects enter. Setting scepticism to one side, there is a perfectly mundane sense in which (...) we may come to have knowledge or fail to have knowledge of such facts. We must perceive objective facts from a perspective, but this does not enter into the facts. Nor does the fact that we must describe facts using language mean that facts are language-dependent.

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)

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)

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 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 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)

Some facts are objective. Some facts are subjective. Subjective facts are personal facts about individuals. It is the purpose of this short note to suggest that subjective facts are in fact objective facts about us. This applies not just to facts involving relations to entities that are independent of us, but to our tastes. It is an objective fact about us that we have the tastes that we do though there may be no objective matter of fact that our tastes (...) reflect or fail to reflect. (shrink)

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)

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)

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 book concentrates on three topics: the problem of the semantic incommensurability of theories; the non-algorithmic character of rational scientific theory choice and naturalised accounts of the rationality of methodological change. The underlying aim is to show how the phenomenon of extensive conceptual and methodological variation in science need not give rise to a thorough-going epistemic or conceptual relativism.

Truth in a correspondence sense is objective in two ways. It is objective because the relation of correspondence is objective and because the facts to which truths correspond are objective. Truth about artifacts is problematic because artifacts are intentionally designed to perform certain functions, and so are not entirely mind independent. Against this, it is argued in this paper that truth about artifacts is perfectly objective despite the role played by intention and purpose in the production of artifacts.

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)

This paper brings Sellars’ synoptic vision of philosophy into contact with elements of Quine’s naturalism. The implications of the synoptic view for the method of analysis are presented. Sellars’ metaphysical naturalism is supplemented with the meta-philosophical and epistemological naturalism of Quine. The issue of epistemic normativity is addressed within a naturalistic context. The possibility of a conflict between naturalism and realism is considered.

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.

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)

This paper reconsiders the challenge presented to scientific realism by the semantic incommensurability thesis. A twofold distinction is drawn between methodological and semantic incommensurability, and between semantic incommensurability due to variation of sense and due to discontinuity of reference. Only the latter presents a challenge to scientific realism. The realist may dispose of this challenge on the basis of a modified causal theory of reference, as argued in the author’s 1994 book, The incommensurability thesis. This referential response has been the (...) subject of a charge of meta-incommensurability by Hoyningen-Huene et al., who argue that the realist’s referential response begs the question against anti-realist advocates of incommensurability. In reply, it is noted that a tu quoque rejoinder is available to the realist. It is also argued that the dialectical situation favours the scientific realist, since the anti-realist defence of incommensurability depends on an incoherent distinction between phenomenal world and world-in-itself. In light of such incoherence, and a strong commonsense presumption in favour of realism, the referential response to semantic incommensurability may be justifiably based on realism. (shrink)

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)

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 criticisms of the concept of untranslatability which Davidson and Putnam have raised against the incommensurability thesis.

The aim of this paper is to bring the resources of virtue epistemology to bear on the issue of the epistemic objectivity of science. A distinction is made between theoretical virtues that may be possessed by scientific theories and epistemic virtues that may be exercised by individual scientists. A distinction is then made between ontological objectivity, objectivity of truth and epistemic objectivity, the latter being the principal focus of the paper. It is then noted that a role must be played (...) by deliberative judgement in determining how to apply the theoretical virtues. It is suggested that such judgement may be virtuous in light of the exercise of the epistemic virtues. It is argued that the primary location of epistemic objectivity is the theoretical virtues, whereas the epistemic virtues of scientists play a subordinate role. (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 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 addresses the issue of how it is possible to understand the language of an incommensurable theory. The aim is to defend the idea of translation failure against the objection that it incoherently precludes understanding.

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)

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)

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.

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.

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.

¿La ciencia otorga conocimiento de la realidad? En este artículo ofrezco una respuesta positiva a esta pregunta. Rechazo la pretensión anti-realista según la cual somos incapaces de adquirir conocimiento de la realidad; al contrario, apoyo la visión realista que afirma que la ciencia produce conocimiento del mundo externo. Pero: ¿cuál mundo es ese? Algunos sostienen que la ciencia conduce a la superación de nuestra visión del mundo dada por el sentido común. El sentido común es la “metafísica de la edad (...) de piedra” que debe rechazarse como la teoría falsa de nuestros primitivos ancestros. Contra tales eliminativistas acerca del sentido común, planteo que la ciencia conserva y explica la experiencia del mundo dada por el sentido común. Aunque la ciencia puede llevar a la superación de creencias profundamente arraigadas, el sentido común refleja un nivel de experiencia más básico y duradero. Las creencias del sentido común son creencias bien confirmadas que se justifican por su papel en la acción práctica exitosa de la vida diaria. El sentido común otorga una base sólida sobre la cual establecer el enfoque realista a la ciencia. -/- . (shrink)

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.

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.

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

The New Zealand philosopher, Robert Nola (1940-2022), has died. He was a kind man, a good friend, and a fine philosopher. Here is how I remember him.

The idea that science is objective, or able to achieve objectivity, is in large part responsible for the role that science plays within society. But what is objectivity? The idea of objectivity is ambiguous. This paper distinguishes between three basic forms of objectivity. The first form of objectivity is ontological objectivity: the world as it is in itself does not depend upon what we think about it; it is independent of human thought, language, conceptual activity or experience. The second form (...) of objectivity is the objectivity of truth: truth does not depend upon what we believe or justifiably believe; truth depends upon the way reality itself is. The third form of objectivity is epistemic objectivity: this form of objectivity resides in the scientific method which ensures that subjective factors are excluded, and only epistemically relevant factors play a role in scientific inquiry. The paper considers two problems that arise for the notion of epistemic objectivity: the theory-dependence of observation and the variability of the methods of science. It is argued that the use of shared standard procedures ensures the objectivity of observation despite theory-dependence. It is argued that the variability of methods need not lead to epistemic relativism about science. The paper concludes with the realist suggestion that the best explanation of the success of the sciences is that the methods employed in the sciences are highly reliable truth-conducive tools of inquiry. The objectivity of the methods of the sciences leads to the objective truth about the objective world. (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)

Truth about matters of fact is objective. This is not just because truth is objective. It is also because facts are objective. An objective fact makes an assertion of that fact true. The objectivity of the fact adds a further element of objectivity to the objective truth of the assertion. True assertions of fact are true because truth is objective and because the facts that make them true are objective. True assertions of fact are objective twice over. Their objectivity is (...) twofold. Or, at least, that is the point I seek to establish here. (shrink)

In this paper it is argued that the concept of translation failure involved in Kuhn's thesis of incommensurability is distinct from that of translational indeterminacy in Quine's sense. At most, Kuhnian incommensurability constitutes a weak form of indeterminacy, quite distinct from Quine's. There remains, however, a convergence between the two views of translation, namely, that there is no single adequate translation between languages.

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.

This is a collection of my essays in the philosophy of science which have been translated into Spanish.

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.

It has recently been argued that when one conducts an inquiry into some question one ought to suspend belief with respect to that question. But what about hunches? In this short note, a hunch about the cause of a phenomenon is described. The hunch plays a role in the inquiry into the cause of the phenomenon. It appears that the hunch constitutes a belief that need not be suspended during the inquiry even though belief about the precise cause of the (...) phenomenon is suspended. (shrink)

This paper considers the issue of translation failure between theories from the perspective of a modified causal theory of reference. It is argued that translation failure between theories is in fact a consequence of such a modified causal theory of reference. The paper attempts to show what is right about the incommensurability thesis from the perspective of such a theory of reference. Since relations of co-reference may obtain between theories in the absence of translation, incomparability of content does not follow (...) from failure of translation. (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)

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”.

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)

I distinguish three primary notions of objectivity that may be applied to the sciences. There is an ontological sense of objectivity which relates to the way in which the natural world exists independently of human thought. There is a semantic form of objectivity which relates to the nature of truth. There is an epistemic notion of objectivity which relates to the methodological norms and procedures which are employed in the sciences, and the epistemic justification of beliefs and theories which are (...) licensed by those norms and procedures. These three forms of objectivity may be brought into conjunction. It is because we employ methods of scientific inquiry which function to exclude subjective factors and to incorporate only genuinely epistemic factors that the results and theories of the sciences should be accepted. They should be accepted because by employing such methods we have the best chance of arriving at true beliefs about the nature of reality. In short, it is the epistemic objectivity of the methods of science that leads us to the objective truth about the objective world. (shrink)
