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.

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

Según el realismo científico, el propósito de la ciencia es descubrir la verdad acerca de los aspectos observables e inobservables de la realidad objetiva e independiente de la mente, en la cual habitamos. Putnam y otros han objetado que tal posición realista metafísica presupone un punto de vista del Ojo de Dios, del cual no puede establecerse ningún sentido coherente. En este artículo defenderé dos posiciones: primera, que el realismo científico no requiere la adopción de un punto de vista del Ojo de Dios; en lugar de esto, plantearé que el realismo científico es una hipótesis acerca de la relación entre la teoría científica y la realidad que puede ser propuesta desde nuestra propia perspectiva humana. Segunda, incluso si el realismo científico requiriera un punto de vista del Ojo de Dios, no necesariamente estaría en detrimento del realismo, pues es posible desarrollar una perspectiva externa inteligible acerca de las relaciones epistémicas humanas que se entretejen con nuestra realidad circundante.

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.

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.

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.

Incommensurability and Related Matters draws together some of the most distinguished contributors to the critical literature on the problem of the incommensurability of scientific theories. It addresses all the various problems raised by the problem of incommensurability, such as meaning change, reference of theoretical terms, scientific realism and anti-realism, rationality of theory choice, cognitive aspects of conceptual change, as well as exploring the broader implications of incommensurability for cultural difference. While it offers new work, and new directions of discussion, on the topic of incommensurability, the book also recapitulates the history of the discussion of the topic that has taken place within the literature on incommensurability.

The aim of this paper is to make a distinction between a number of different varieties of cognitive relativism. The focus is cognitive relativism rather than relativism about morality or cultural practicies. I distinguish between five varieties of cognitive relativism: relativism about rationality; relativism about truth; relativism about knowledge; relativism about reality; conceptual relativism. The paper may also be found in my book, Rationality, Relativism and Incommensurability (chapter one).

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.

This volume of essays about Thomas Kuhn contains new work by key figures in the area of Kuhn-studies. The essays treat Kuhn primarily as a philosopher rather than historian of science. They analyze the background setting of Kuhn’s ideas, and cover such topics as his account of scientific practice, cognitive aspects of scientific reasoning and conceptual change, and Kuhn’s influence on feminist philosophy of science. While the volume is principally conceived as an introduction to Kuhn for the generalist, it contains much that will be of interest to specialists. The essays combine criticism with exposition. But the volume also has a prospective orientation. For it seeks to place Kuhn’s ideas within the frame of ongoing and future developments in the philosophy of science. The volume opens with an Introduction by the Editor, Thomas Nickles, and closes with a select bibliography of English-language literature relating to Kuhn.

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 principle areas covered are: 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? 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? 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? Pandispositionalism: Could all properties be dispositional in nature? 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.

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.

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.
