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 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 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)

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. -/- .

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.

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.

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 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)

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.

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 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)

Some comments on descriptive and normative aspects of Kuhn's account 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.

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. (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)

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.

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

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 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)

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)

¿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)

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

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

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.

Thomas S. Kuhn’s The structure of scientific revolutions is a classic text in the history and philosophy of science. It is one of the best known works in the field outside this area of academic specialization. One need only mention the term ‘paradigm’ to register the extent to which Kuhn’s ideas have entered the vernacular. Traditionally, philosophers of science have tended to focus on questions about the nature of scientific method. Kuhn brought a historical orientation to bear on such questions. (...) Structure opens with the words, ‘History, if viewed as a repository for more than anecdote or chron- ology could produce a decisive transformation in the image of science by which we are now possessed’ (p.1). Kuhn proposed a model of scientific change, that empha- sizes historical development. As Kuhn foresaw, reflection on its history has transformed our image of science. Science is now seen as a developing process, practised by humans in a variety of shifting historical and social circumstances. (shrink)

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 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)

El año 1962 vio la introducción, por parte de Kuhn y Feyerabend, de la tesis de la inconmensurabilidad de las teorías científicas . Desde entonces, la tesis ha sido debatida ampliamente y ha atraído muchos críticos. Su influencia aún es considerable, particularmente en las áreas de la historia y la filosofía de la ciencia interesadas en el cambio y la elección de teorías. Esta influencia se debe, en gran medida, a la inmensa popularidad de la obra maestra de Kuhn, La (...) Estructura de las revoluciones científicas, la cual asegura que la idea de la inconmensurabilidad continúe alcanzando un público amplio. Sin embargo, no es tan ampliamente apreciado que la versión de Kuhn de la inconmensurabilidad ha ido sufriendo, con el tiempo, un proceso continuo de revisión y clarificación. Como resultado de esto, la versión de la tesis por la que Kuhn es mejor conocido difiere notablemente de la versión que él asume en el presente. En este artículo presento un estudio del proceso de cambio, caracterizando las etapas principales por las que transcurre el concepto kuhniano de inconmensurabilidad. (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)

The paper examines the role played by the notion of truth in the version of scientific realism known as scientific entity realism. Scientific entity realism is the thesis that the unobservable entities postulated by scientific theories are real. As such, it is an ontological thesis about the existence of certain entities. By contrast, scientific realism is often characterised as a thesis primarily involving the truth of theories. Sometimes scientific realism is expressed as the thesis that theoretical statements are intended as (...) true descriptions of reality. Another favoured theme is that theoretical statements are objectively true or false in virtue of the way the world is independently of us. To such formulations it is usually added that the sense of 'true' required by scientific realism is the correspondence sense. To mark the contrast with scientific entity realism, I shall say that a formulation of scientific realism in terms of truth is a semantic version of scientific realism.

The year 2012 marks the fiftieth anniversary of the original publication of Thomas Kuhn’s famous book, The Structure of Scientific Revolutions. Kuhn, who taught at Berkeley, Princeton and MIT following studies in physics at Harvard, was a historian of science whose ideas have had a major impact on the philosophy of science. Now in its third edition, Structure has had a lasting influence on our thinking about science. After fifty years, Kuhn’s ideas show signs of wear. But they continue to (...) shape our “image of science”, to echo Kuhn’s own turn of phrase in the opening lines of Structure. The core idea of Structure is that scientific research is based on underlying theoretical structures which provide a framework for research in a field for a sustained period of time. Kuhn’s name for these structures was paradigm. It is Kuhn’s use of the word that inserted ‘paradigm’ into the popular lexicon. His original use of the word was flexible. But he had two key points in mind. First, there is a set of beliefs about a domain of study, including generalizations and a model of how the domain is constituted, that is adopted as the basis for scientific practice in a scientific field at a time. Second, there are a number of important examples of exemplary scientific research which later scientists look back to as guiding inspiration for their own research. Examples include Copernican heliocentric astronomy, Lavoisier’s oxygen-based chemistry and Darwin’s theory of evolution by natural selection. All of these constituted paradigms for scientists working in these areas for a significant period of time, both in the sense of providing an overarching set of beliefs about the world and in the sense of providing examples of exemplary research.

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.

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)

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.

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.

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.

Quelques remarques à propos du lien entre Chisholm et la réponse proposée au relativisme épistémique sont aussi offertes. (shrink)

Is there one univocal or generic notion of ground? Monists answer yes, while pluralists answer no. Pluralists argue that monism cannot meet plausible constraints on an adequate theory of ground. My aim in this paper is to articulate a monist theory of ground that can satisfy the pluralist constraints in a way that leaves the pluralists with no reasons not to endorse the monist picture of ground. I do this by adopting a tripartite conception of ground and then showing that (...) it has the resources to vindicate monism while satisfying the pluralist constraints on a theory of ground.

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.

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)

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)

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)

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)

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.

Mark Schroeder has argued that all reasonable forms of inconsistency of attitude consist of having the same attitude type towards a pair of inconsistent contents (A-type inconsistency). We suggest that he is mistaken in this, offering a number of intuitive examples of pairs of distinct attitudes types with consistent contents which are intuitively inconsistent (B-type inconsistency). We further argue that, despite the virtues of Schroeder's elegant A-type expressivist semantics, B-type inconsistency is in many ways the more natural choice in developing (...) an expressivist account of moral discourse. We close by showing how to adapt ordinary formality-based accounts of logicality to define a B-type account of logical inconsistency and distinguish it from both semantic and pragmatic inconsistency. In sum, we provide a roadmap of how to develop a successful B-type expressivism. (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)

For Kuhn, there are a number of values which provide scientists with a shared basis for theory-choice. These values include accuracy, breadth, consistency, simplicity and fruitfulness. Each of these values may be interpreted in different ways. Moreover, there may be conflict between the values in application to specific theories. In this short paper, Kuhn's idea of scientific values is extended to the value of academic freedom. The value of academic freedom may be interpreted in a number of different ways. Moreover, (...) there are other values which play a role in the functioning of our academic institutions. As with the possible conflict between scientific values, there may be conflict among the academic values. (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 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.

Early discussions of ?climate justice? have been dominated by economists rather than political philosophers. More recently, analytical liberal political philosophers have joined the debate. However, the philosophical discussion of climate justice remains in its early stages. This paper considers one promising approach based on human rights, which has been advocated recently by several theorists, including Simon Caney, Henry Shue and Tim Hayward. A basic argument supporting the claim that anthropogenic climate change violates human rights is presented. Four objections to this (...) argument are examined: the ?future persons? objection; the ?risk? objection; the ?collective causation? objection; and the ?demandingness? objection. This critical examination leads to a more detailed specification and defence of the claim that anthropogenic climate change violates human rights. (shrink)
