Here we challenge the orthodoxy according to which abduction is an a posteriori mode of inference. We start by providing a case study illustrating how abduction can justify a philosophical claim not justifiable by empirical evidence alone. While many grant abduction's epistemic value, nearly all assume that abductive justification is a posteriori, on grounds that our belief in abduction's epistemic value depends on empirical evidence about how the world contingently is. Contra this assumption, we argue, first, that our belief in (...) abduction’s epistemic value is not and could not be justified a posteriori, and second, that attention to the roles experience plays in abductive justification supports taking abduction to be an a priori mode of inference. We close by highlighting how our strategy for establishing the a priority of abduction positively contrasts with strategies in Bonjour (1998), Swinburne (2001), and Peacocke (2004) aiming to establish the a priority of certain ampliative modes of inference or abductive principles.

Despite numerous and increasing attempts to define what life is, there is no consensus on necessary and sufficient conditions for life. Accordingly, some scholars have questioned the value of definitions of life and encouraged scientists and philosophers alike to discard the project. As an alternative to this pessimistic conclusion, we argue that critically rethinking the nature and uses of definitions can provide new insights into the epistemic roles of definitions of life for different research practices. This paper examines the possible (...) contributions of definitions of life in scientific domains where such definitions are used most (e.g., Synthetic Biology, Origins of Life, Alife, and Astrobiology). Rather than as classificatory tools for demarcation of natural kinds, we highlight the pragmatic utility of what we call operational definitions that serve as theoretical and epistemic tools in scientific practice. In particular, we examine contexts where definitions integrate criteria for life into theoretical models that involve or enable observable operations. We show how these definitions of life play important roles in influencing research agendas and evaluating results, and we argue that to discard the project of defining life is neither sufficiently motivated, nor possible without dismissing important theoretical and practical research.

Since Saul Kripke’s and Hilary Putnam’s groundbreaking work in the Seventies, the idea has emerged that natural kind terms are semantically special among common nouns. Stephen P. Schwartz, for example, has argued that an artifactual kind term like “pencil” functions very differently from a natural kind term like “tiger.” This, however, blatantly violates a principle that I call Semantic Uniformity. In this paper, I defend the principle. In particular, I outline a picture of how natural kind terms function based on (...) Kripke’s and Putnam’s considerations, and I use it to rebut Schwartz’s arguments, showing that if it works for natural kind terms, it can work for artifactual kind terms too, or at least that Schwartz did not provide good enough reasons to the contrary.

In this paper, I try to outline what I take to be Naming and Necessity’s fundamental legacy to my generation and those that follow, and the new perspectives it has opened up for twenty-first century philosophy. The discussion is subdivided into three sections, concerning respectively philosophy of language, metaphysics, and metaphilosophy. The general unifying theme is that Naming and Necessity is helping philosophy to recover a Golden Age, by freeing it from the strictures coming from the empiricist and Kantian traditions (...) and reconnecting it to the world and the objects that populate it. Because of this, in the concluding paragraph I tentatively suggest that Kripke’s philosophy may be seen as a sui generis form of naturalism. (shrink)

The aim of this paper is to show what sorts of logics are required by externalist and internalist accounts of the meanings of natural kind nouns. These logics give us a new perspective from which to evaluate the respective positions in the externalist-internalist debate about the meanings of such nouns. The two main claims of the paper are the following: first, that adequate logics for internalism and externalism about natural kind nouns are second-order logics; second, that an internalist second-order logic (...) is a free logic—a second order logic free of existential commitments for natural kind nouns, while an externalist second-order logic is not free of existential commitments for natural kind nouns—it is existentially committed.

In Direct Belief I argue for the Theory of Direct Belief, which treats having a belief about an individual as an unmediated relation between the believer and the individual the belief is about. After a critical review of alternative positions, I use Grice’s theory of conversational implicature to provide a detailed pragmatic account of substitution failure in belief ascriptions and go on to defend this view against objections, including those based on an unwarranted “Inner Speech” Picture of Thought. The work (...) serves as a case study in pragmatic explanation, dealing also with methodological issues about context-sensitivity in language and the relation between semantics and pragmatics.

This paper addresses the question whether introspection plus externalism about mental content warrant an a priori refutation of external-world skepticism and ontological solipsism. The suggestion is that if thought content is partly determined by affairs in the environment and if we can have non-empirical knowledge of our current thought contents, we can, just by reflection, know about the world around us -- we can know that our environment is populated with content-determining entities. After examining this type of transcendental argument and (...) discussing various objections found in the literature, I argue that the notion of privileged self-knowledge underlying this argument presupposes that we can learn, via introspection, that our so-called thoughts are propositional attitudes rather than contentless states. If, however, externalism is correct and thought content consists in the systematic dependency of internal states on relational properties, we cannot know non-empirically whether or not we have propositional attitudes. Self-knowledge (apropositional attitude) is consistent with us lacking the ability to rule out, via introspection, the possibility that we don't have any propositional attitudes. Self-knowledge provides us with knowledge of what is in our minds, but not that we have minds. Hence, the combination of externalism with the doctrine of privileged self-knowledge does not allow for an a priori refutation of skepticism and is therefore unproblematic. (shrink)

This paper explores Kornblith's proposal in "Knowledge and its Place in Nature" that knowledge is a natural kind that can be elucidated and understood in scientific terms. Central to Kornblith's development of this proposal is the claim that there is a single category of unreflective knowledge that is studied by cognitive ethologists and is the proper province of epistemology. This claim is challenged on the grounds that even unreflective knowledge in language-using humans reflects forms of logical reasoning that are in (...) principle unavailable to nonlinguistic animals.

Two-dimensional semantics aims to eliminate the puzzle of necessary a posteriori and contingent a priori truths. Recently many argue that even assuming two-dimensional semantics we are left with the puzzle of necessary and a posteriori propositions. Stephen Yablo (Pacific Philosophical Quarterly, 81, 98–122, 2000) and Penelope Mackie (Analysis, 62(3), 225–236, 2002) argue that a plausible sense of “knowing which” lets us know the object of such a proposition, and yet its necessity is “hidden” and thus a posteriori. This paper answers (...) this objection; I argue that given two-dimensional semantics you cannot know a necessary proposition without knowing that it is true. (shrink)

Whither the philosophy of intuition?Herman Cappelen’s Philosophy Without Intuitions (PWI) is a novel study in philosophical sociology—or, as Cappelen at one point suggests, “intellectual anthropology” (96).All undated references are to Cappelen (2012). Its target is the thesis that intuition is central, in the descriptive sense that contemporary analytic philosophers rely on intuitions for evidence—or, more generally, positive epistemic status. Cappelen labels the target thesis Centrality.If Centrality is true, then especially urgent are two questions in the rapidly growing field that is (...) the philosophy of intuition:[Q1] What are intuitions?[Q2] Can intuitions serve as evidence?There are of course others, but in chapter one Cappelen singles out these two as The Burning Questions about intuition. He then summarizes the overall upshot of PWI as follows:In this book I argue that Centrality, on any reasonable interpretation, is false. If you share that view, the Burning Questions will no lo ..

This paper focuses on the linguistic evidence base provided by proponents of conceptualism (e.g., Chomsky) and rational realism (e.g., Katz) and challenges some of the arguments alleging that the evidence allowed by conceptualists is superior to that of rational realists. Three points support this challenge. First, neither conceptualists nor realists are in a position to offer direct evidence. This challenges the conceptualists’ claim that their evidence is inherently superior. Differences between the kinds of available indirect evidence will be discussed. Second, (...) at least some of the empirical evidence provided by the conceptualist is flawed. It is not obtained independently of theoretical commitments, alternative interpretations have not been ruled out, and some of the thought experiments intended to extend the evidence base are conceptually flawed. Third, the widely held assumption that rational realism disallows empirical evidence relevant to linguistics is dubious. It will be shown that the limitation imposed by rational realism concerns strictly formal linguistics. The rationalist realist has no reason to impose any restriction on the evidence relevant to psycholinguistics. I conclude that it is a mistake to dismiss realism based on the assumption that it imposes undue restrictions on evidence that is relevant to linguistics. (shrink)

Non-descriptivists in metaethics should say more about intuitions. For one popular theory has it that case-based intuitions are in the business of correctly categorizing or classifying merely by bringing to bear a semantic or conceptual competence. If so, then the fact that all normative predicates have case-based intuitions involving them shows that they too are in the business of categorizing or classifying things. This favors a descriptivist position in metaethics—normative predicates have descriptive content—and disfavors a purely non-descriptivist position, like pure (...) expressivism. However, we can say more. We can distinguish two different sorts of intuitional state, A-grade intuitions and B-grade intuitions, based on a cluster of properties that are distinctive of each. While a hypothesis about categorization best explains the cluster of properties enjoyed by A-grade intuitions, it does not best explain the cluster of properties enjoyed by B-grade intuitions. Indeed, a non-categorizational, attitude-expressive hypothesis about the relevant meanings best explains B-grade intuitions. And intuitions involving thin normative predicates are B-grade. So intuition theory supports non-descriptivism, not descriptivism, about thin normative predicates. (shrink)

This paper considers normative naturalism, understood as the view that (i) normative sentences are descriptive of the way things are, and (ii) their truth/falsity does not require ontology beyond the ontology of the natural world. Assuming (i) for the sake of argument, I here show that (ii) is false not only as applied to ethics, but more generally as applied to practical and epistemic normativity across the board. The argument is a descendant of Moore's Open Question Argument and Hume's Is-Ought (...) Gap. It goes roughly as follows: to ensure that natural ontology suffices for normative truth, there must be semantically grounded entailments from the natural truths to the normative truths. There are none. So natural ontology does not suffice for normative truth. (shrink)

Epiphenomenalism denies some or all putative cases of mental causation. The view is widely taken to be absurd: if a theory can be shown to entail epiphenomenalism, many see that as a reductio of that theory. Opponents take epiphenomenalism to be absurd because they regard the view as undermining the evident agency we have in action and precluding substantial self-knowledge. In this paper, I defend epiphenomenalism against these objections, and thus against the negative dialectical role that the view plays in (...) philosophy of mind. I argue that nearly in all cases where a theory implies one kind of epiphenomenalism, it is an epiphenomenalism of a non-problematic kind, at least as far as issues about agency and self-knowledge are concerned. There is indeed a problematic version of epiphenomenalism, but that version is not relevant to the debates where its apparent absurdity is invoked. (shrink)

The Physical Intentionality Thesis claims that dispositions share the marks of psychological intentionality; therefore, intentionality is not exclusively a mental phenomenon. Beyond the standard five marks, Alexander Bird introduces two additional marks of intentionality that he argues dispositions do not satisfy: first, thoughts are extrinsic; second, the direction of causation is that objects cause thoughts, not vice versa. In response, this paper identifies two relevant conceptions of extrinsicness, arguing that dispositions show deep parallels to thoughts on both conceptions. Then, it (...) shows that Bird’s discussion of direction of causation overlooks complexities of dispositionality and intentionality that problematize apparent differences between thoughts and dispositions. The paper ends with a discussion of why we find these parallels between thoughts and dispositions. (shrink)

In 1955, Goodman set out to 'dissolve' the problem of induction, that is, to argue that the old problem of induction is a mere pseudoproblem not worthy of serious philosophical attention. I will argue that, under naturalistic views of the reflective equilibrium method, it cannot provide a basis for a dissolution of the problem of induction. This is because naturalized reflective equilibrium is -- in a way to be explained -- itself an inductive method, and thus renders Goodman's dissolution viciously (...) circular. This paper, then, examines how the old problem of induction crept back in while nobody was looking. (shrink)

In 1955, Goodman set out to ‘dissolve’ the problem of induction, that is, to argue that the old problem of induction is a mere pseudo‐problem not worthy of serious philosophical attention. This dissolution, which has enjoyed tremendous acceptance, essentially involved an application of what has since been called the method of reflective equilibrium. Largely in connection with naturalism in epistemology, the reflective equilibrium method has lately been the subject of considerable attention. I will argue that, under naturalistic views of the (...) reflective equilibrium method, it cannot provide a basis for a dissolution of the problem of induction. This is because naturalized reflective equilibrium is – in a way to be explained – itself an inductive method, and thus renders Goodman's dissolution viciously circular.

The history of so-called ‘linguistic relativity’ is an odd and multifaceted one. After knowing alternate fortunes and being treated by different academic branches, today there are some new ways of investigating the language-thought-reality problem that put into dialogue the latest trends in language-related disciplines generate room for philosophical themes previously overlooked, reassess the very idea of linguistic relativity, despite its popularized versions which have circulated for decades and which have led an otherwise fruitful debate to extremes. It is argued that (...) a multidisciplinary approach is desirable in order to broaden future research. In the last few years the opportunity to study this matter following a common trend in several disciplines has been created. Language, and cognition too, are now conceived as intrinsically social phenomena. It is argued that relativistic effects should be investigated in social realms, and that analytic philosophy could help with this task. (shrink)

A recent and growing discussion in philosophy addresses the construction of models and their use in scientific reasoning by comparison with fiction. This comparison helps to explore the problem of mediated observation and, hence, the lack of an unambiguous reference of representations. Examining the usefulness of the concept of fiction for a comparison with non-denoting elements in science, the aim of this paper is to present reasonable grounds for drawing a distinction between these two kinds of representation. In particular, my (...) account will suggest a demarcation between fictional and non-fictional discourse as involving two different ways of interpreting representations. This demarcation, leading me to distinguish between fictional and non-fictional forms of enquiry, will provide a useful tool to explore to what extent the descriptions given by a model can be justified as making claims about the world and to what degree they are a consequence of the model’s particular construction.

This essay examines the proposal that psychological essentialism results from a history of natural selection acting on human representation and inference systems. It has been argued that the features that distinguish essentialist representational systems are especially well suited for representing natural kinds. If the evolved function of essentialism is to exploit the rich inductive potential of such kinds, then it must be subserved by cognitive mechanisms that carry out at least three distinct functions: identifying these kinds in the environment, constructing (...) essentialized representations of them, and constraining inductive inferences about kinds. Moreover, there are different kinds of kinds, ranging from nonliving substances to biological taxa to within-species kinds such as sex, and the causal processes that render these categories coherent for the purposes of inductive generalization vary. If the evolved function of essentialism is to support inductive generalization under ignorance of true causes, and if kinds of kinds vary in the implicit assumptions that support valid inductive inferences about them, then we expect different, functionally incompatible modes of essentialist thinking for different kinds. In particular, there should be differences in how biological and nonbiological substances, biological taxa, and biological and social role kinds are essentialized. The functional differences between these kinds of essentialism are discussed. (shrink)

The classical view of the relationship between necessity and apriority, defended by Leibniz and Kant, is that all necessary truths are known a priori. The classical view is now almost universally rejected, ever since Saul Kripke and Hilary Putnam discovered that there are necessary truths that are known only a posteriori. However, in recent years a new debate has emerged over the epistemology of these necessary a posteriori truths. According to one view – call it the neo-classical view – knowledge (...) of a necessary truth always depends on at least one item of a priori knowledge. According to the rival view – call it the neoempiricist view – our knowledge of necessity is sometimes broadly empirical. In this paper I present and defend an argument against the neo-empiricist view. I argue that knowledge of the necessity of a necessary truth could not be broadly empirical. (shrink)

In this paper Modern Essentialism is used to solve a problem of individuation of spacetime points in General Relativity that has been raised by a New Leibnizian Argument against spacetime substantivalism, elaborated by Earman and Norton. An earlier essentialistic solution, proposed by Maudlin, is criticized as being against both the spirit of metrical essentialism and the fundamental principles of General Relativity. I argue for a modified essentialistic account of spacetime points that avoids those obstacles.

Justin Fisher (2007) has presented a novel argument designed to prove that all forms of mental internalism are false. I aim to show that the argument fails with regard to internalism about phenomenal experiences. The argument tacitly assumes a certain view about the ontology of phenomenal experience, which (inspired by Alva Noe) I call the “snapshot conception of phenomenal experience.” After clarifying what the snapshot conception involves, I present Fisher with a dilemma. If he rejects the snapshot conception, then his (...) argument against phenomenal internalism collapses. But if he embraces the snapshot conception, then internalists may argue that in light of the snapshot conception, their view is not so implausible—and that if Fisher still disagrees, he owes us an argument that shows why phenomenal internalism is false even given the snapshot conception. I conclude the paper by showing that Fisher cannot escape my criticism by adjusting his argument so that it no longer depends on the snapshot conception. (shrink)

Careful scholarship is balanced by original analyses that lead the reader to recognize the limits of meaning, knowledge, and conceptual possibility. The work addresses a host of traditional philosophical problems, among them the nature of space, time, causality, consciousness, the self, other minds, ontology, free will and determinism, and others. The book culminates in a fascinating and profound new understanding of relativity physics and quantum theory.” – Gerhard Preyer, Professor of Philosophy, Goethe-University, Frankfurt am Main, Germany, author of many books including _Concepts of Meaning_, _Beyond Semantics and Pragmatics_, _Intention and Practical Thought_, and _Contextualism in Philosophy_. ●●●●● “[This work’s] goal is of a unique and difficult species: Dr. Bartlett seeks to develop a formal logical calculus on the basis of transcendental philosophical arguments; in fact, he hopes that this calculus will be the formal expression of the transcendental foundation of knowledge.... I consider Dr. Bartlett’s work soundly conceived and executed with great skill.” – C. F. von Weizsäcker, philosopher and physicist, former Director, Max-Planck-Institute, Starnberg, Germany. ●●●●● “Bartlett has written an American “Prolegomena to All Future Metaphysics.” He aims rigorously to eliminate meaningless assertions, reach bedrock, and place philosophy on a firm foundation that will enable it, like science and mathematics, to produce lasting results that generations to come can build on. This is a great book, the fruit of a lifetime of research and reflection, and it deserves serious attention.” — Martin X. Moleski, former Professor, Canisius College, Buffalo, NY, studies of scientific method, the presuppositions of thought, and the self-referential nature of epistemology. ●●●●● “Bartlett has written a book on what might be called the underpinnings of philosophy. It has fascinating depth and breadth, and is all the more striking due to its unifying perspective based on the concepts of reference and self-reference.” – Don Perlis, Professor of Computer Science, University of Maryland, author of numerous publications on self-adjusting autonomous systems and philosophical issues concerning self-reference, mind, and consciousness. ●●●●● ●●●●● The _Critique of Impure Reason: Horizons of Possibility and Meaning_ comprises a major and important contribution to philosophy. Thanks to the generosity of its publisher, this massive 885-page volume has been published as a free open access eBook (3.75MB) as well as an open access printed edition. It inaugurates a revolutionary paradigm shift in philosophical thought by providing compelling and long-sought-for solutions to a wide range of philosophical problems. In the process, the work fundamentally transforms the way in which the concepts of reference, meaning, and possibility are understood. The book includes a Foreword by the celebrated German philosopher and physicist Carl Friedrich von Weizsäcker. ●●●●● In Kant’s _Critique of Pure Reason_ we find an analysis of the preconditions of experience and of knowledge. In contrast, but yet in parallel, the new _Critique_ focuses upon the ways—unfortunately very widespread and often unselfconsciously habitual—in which many of the concepts that we employ _conflict_ with the very preconditions of meaning and of knowledge. ●●●●● This is a book about the boundaries of frameworks and about the unrecognized conceptual confusions in which we become entangled when we attempt to transgress beyond the limits of the possible and meaningful. We tend either not to recognize or not to accept that we all-too-often attempt to trespass beyond the boundaries of the frameworks that make knowledge possible and the world meaningful. ●●●●● The _Critique of Impure Reason_ proposes a bold, ground-breaking, and startling thesis: that a great many of the major philosophical problems of the past can be solved through the recognition of a viciously deceptive form of thinking to which philosophers as well as non-philosophers commonly fall victim. For the first time, the book advances and justifies the criticism that a substantial number of the questions that have occupied philosophers fall into the category of “impure reason,” violating the very conditions of their possible meaningfulness. ●●●●● The purpose of the study is twofold: first, to enable us to recognize the boundaries of what is referentially forbidden—the limits beyond which reference becomes meaningless—and second, to avoid falling victims to a certain broad class of conceptual confusions that lie at the heart of many major philosophical problems. As a consequence, the boundaries of _possible meaning_ are determined. ●●●●● Bartlett, the author or editor of more than 20 books, is responsible for identifying this widespread and delusion-inducing variety of error, _metalogical projection_. It is a previously unrecognized and insidious form of erroneous thinking that undermines its own possibility of meaning. It comes about as a result of the pervasive human compulsion to seek to transcend the limits of possible reference and meaning. ●●●●● Based on original research and rigorous analysis combined with extensive scholarship, the _Critique of Impure Reason_ develops a self-validating method that makes it possible to recognize, correct, and eliminate this major and pervasive form of fallacious thinking. In so doing, the book provides at last provable and constructive solutions to a wide range of major philosophical problems. ●●●●● CONTENTS AT A GLANCE ▪▪▪▪▪ Preface ▪▪▪▪▪ Foreword by Carl Friedrich von Weizsäcker ▪▪▪▪▪ Acknowledgments ▪▪▪▪▪ Avant-propos: A philosopher’s rallying call ▪▪▪▪▪ Introduction ▪▪▪▪▪ A note to the reader ▪▪▪▪▪ A note on conventions ▪▪▪▪▪ ▪▪▪▪▪ ▪▪▪▪▪ PART I ▪▪▪▪▪ ▪▪▪▪▪ WHY PHILOSOPHY HAS MADE NO PROGRESS AND HOW IT CAN ▪▪▪▪▪ 1 Philosophical-psychological prelude ▪▪▪▪▪ 2 Putting belief in its place: Its psychology and a needed polemic ▪▪▪▪▪ 3 Turning away from the linguistic turn: From theory of reference to metalogic of reference ▪▪▪▪▪ 4 The stepladder to maximum theoretical generality ▪▪▪▪▪ ▪▪▪▪▪ ▪▪▪▪▪ PART II ▪▪▪▪▪ THE METALOGIC OF REFERENCE ▪▪▪▪▪ A New Approach to Deductive, Transcendental Philosophy ▪▪▪▪▪ 5 Reference, identity, and identification ▪▪▪▪▪ 6 Self-referential argument and the metalogic of reference ▪▪▪▪▪ 7 Possibility theory ▪▪▪▪▪ 8 Presupposition logic, reference, and identification ▪▪▪▪▪ 9 Transcendental argumentation and the metalogic of reference ▪▪▪▪▪ 10 Framework relativity ▪▪▪▪▪ 11 The metalogic of meaning ▪▪▪▪▪ 12 The problem of putative meaning and the logic of meaninglessness ▪▪▪▪▪ 13 Projection ▪▪▪▪▪ 14 Horizons ▪▪▪▪▪ 15 De-projection ▪▪▪▪▪ 16 Self-validation ▪▪▪▪▪ 17 Rationality: Rules of admissibility ▪▪▪▪▪ ▪▪▪▪▪ ▪▪▪▪▪ PART III ▪▪▪▪▪ PHILOSOPHICAL APPLICATIONS OF THE METALOGIC OF REFERENCE ▪▪▪▪▪ Major Problems and Questions of Philosophy and the Philosophy of Science ▪▪▪▪▪ 18 Ontology and the metalogic of reference ▪▪▪▪▪ 19 Discovery or invention in general problem-solving, mathematics, and physics ▪▪▪▪▪ 20 The conceptually unreachable: “The far side” ▪▪▪▪▪ 21 The projections of the external world, things-in-themselves, other minds, realism, and idealism ▪▪▪▪▪ 22 The projections of time, space, and space-time ▪▪▪▪▪ 23 The projections of causality, determinism, and free will ▪▪▪▪▪ 24 Projections of the self and of solipsism ▪▪▪▪▪ 25 Non-relational, agentless reference and referential fields ▪▪▪▪▪ 26 Relativity physics as seen through the lens of the metalogic of reference ▪▪▪▪▪ 27 Quantum theory as seen through the lens of the metalogic of reference ▪▪▪▪▪ 28 Epistemological lessons learned from and applicable to relativity physics and quantum theory ▪▪▪▪▪ ▪▪▪▪▪ PART IV ▪▪▪▪▪ HORIZONS ▪▪▪▪▪ 29 Beyond belief ▪▪▪▪▪ 30 _Critique of Impure Reason_: Its results in retrospect ▪▪▪▪▪ ▪▪▪▪▪ SUPPLEMENT ▪▪▪▪▪ The Formal Structure of the Metalogic of Reference ▪▪▪▪▪ APPENDIX I ▪▪▪▪▪ The Concept of Horizon in the Work of Other Philosophers ▪▪▪▪▪ APPENDIX II ▪▪▪▪▪ Epistemological Intelligence ▪▪▪▪▪ References ▪▪▪▪▪ Index ▪▪▪▪▪ About the author.

This article argues for a different outlook on the concept of extension, especially for the reference of general terms in scientific practice. Scientific realist interpretations of the two predominant theories of meaning, namely Descriptivism and Causal Theory, contend that a stable cluster of descriptions or an initial baptism fixes the extension of a general term such as a natural kind term. This view in which the meaning of general terms is presented as monosemantic and the referents as stable, homogeneous, and (...) unchangeable, however, does not reflect the various practices involved in the investigation of research materials and the related application of general terms in scientific practice. By drawing on the taxonomic diversity, particularly of structure-based classifications in chemical databases, this article illustrates the limited utility of such a concept of extension. Research materials often exhibit a plurality of material dimensions that, within different research contexts, allow for various and often equally significant taxonomic demarcations. In light of this, the extension of a general term cannot be uniquely determined by a supposedly independent nature of the referent but is relative to the model context under which the materials are investigated. This significance and plurality of the model context, I claim, needs to be mirrored in an account of meaning that is supposed to reflect scientific reality. On this account, the aim of this article is to present an alternative perspective on the concept of extension to accommodate the diverse material practices that determine the application of general terms in science.

A posteriori Moral Naturalism posits a posteriorimoral/naturalistic identities. Versions of this view thatposit necessary identities purport to rely on theKripke/Putnam doctrine of scientific essentialism.Versions that posit only contingent identities requirethat moral terms are non-rigid designators. I argue thatmetaethics does not fall within the scope of scientificessentialism and that moral terms are not non-rigid designators.

The rapid development of natural language processing in the last three decades has drastically changed the way professional translators do their work. Nowadays most of them use computer-assisted translation or translation memory tools whose evolution has been overshadowed by the much more sensational development of machine translation systems, with which TM tools are sometimes confused. These two language technologies now interact in mutually enhancing ways, and their increasing role in human translation has become a subject of behavioral studies. Philosophers and (...) linguists, however, have been slow in coming to grips with these important developments. The present paper seeks to fill in this lacuna. I focus on the semantic aspects of the highly distributed human–computer interaction in the CAT process which presents an interesting case of an extended cognitive system involving a human translator, a TM tool, an MT engine, and sometimes other human translators or editors. Considered as a whole, such a system is engaged in representing the linguistic meaning of the source document in the target language. But the roles played by its various components, natural as well as artificial, are far from trivial, and the division of linguistic labor between them throws new light on the familiar notions that were initially inspired by rather different phenomena in the philosophy of language, mind, and cognitive science.

It is widely believed that Twin-Earth-style thought experiments show that the contents of a person's thoughts fail to supervene on her intrinsic properties. Several recent philosophers have made the further claim that Twin-Earth-style thought experiments produce metaphysically necessary conditions for the possession of certain concepts. I argue that the latter view is false, and produce counterexamples to several proposed conditions. My thesis is of particular interest because it undermines some attempts to show that externalism is incompatible with privileged access.

This paper develops and critiques the two-dimensionalist account of mental content developed by David Chalmers. I first explain Chalmers's account and show that it resists some popular criticisms. I then argue that the main interest of two-dimensionalism lies in its accounts of cognitive significance and of the connection between conceivability and possibility. These accounts hinge on the claim that some thoughts have a primary intension that is necessarily true. In this respect, they are Carnapian, and subject to broadly Quinean attack. (...) The remainder of the paper advances such an attack. I argue that there are possible thinkers who are willing to revise their beliefs in response to expert testimony, and that such thinkers will have no thoughts with necessary primary intensions. I even suggest that many actual humans may well be such thinkers. I go on to argue that these possible thinkers show that the two-dimensionalist accounts fail. (shrink)

Millians about proper names typically claim that it is knowable apriori that Hesperus is Phosphorus. We argue that they should claim instead that it is knowable only aposteriori that Hesperus is Hesperus, since the Kripke-Putnam epistemic arguments against descriptivism are special cases of Quinean arguments that nothing is knowable apriori, and Millians have no resources to resist the more general Quinean arguments.

Ecological developmental biology considers the phenotype as actively produced through an environmentally informed process of individual development, rather than predetermined by the genotype. Accordingly, the genotype is viewed as one among many interactants that contribute formative elements; it is understood to do so no differently from the way other organism-internal and environmental resources do. Although the EcoDevo approach is evidently particularly apt to inform approaches to human development, which mostly takes shape in rich cultural environments, it is remarkable that, at (...) least within some highly influential circles of the linguistic sciences, the study of many distinctive human cognitive traits including language remains strongly anchored to a preformationist stance. This article brings an EcoDevo approach to the biologically focused study of language to argue that an aspect of language design commonly assumed to be “blueprinted,” namely, the lexicon-syntax interface, may instead be explained as a plastic effect of ongoing developmental processes in the mind of the child, in which designated aspects of the environment fulfill a key constructive role.

Wir stellen ein präzises Modell der wissenschaftlichen Begriffs-theorie vor, in dem die Beschreibungs-, die Wirklichkeits- und die mengentheoretische Ebene verknüpft werden. Einerseits wird ein allgemeiner Rahmen für die Gesamtheit der Begriffe, andererseits die „lokale” Struktur eines Begriffs beschrieben. Wir spezialisieren diesen Rahmen auf wissenschaftliche Begriffe, wissenschaftliche Theorien, und auf die zugehörigen strukturalistischen, wissenschaftstheoretischen Konstruktionen. We introduce a precise model for the theory of concepts in philosophy of science. In this model we connect the level of description, the level of reality (...) and the level of set theoretic systems. On the one hand we describe a general frame for the collection of concepts, and on the other hand the „local” structure of a concept. We specialize this frame to scientific concepts, scientific theories, and to the appertaining structuralist constructions from philosophy of science. (shrink)

This paper does two things. First, it argues for a metaphilosophical view of conceptual analysis questions; in particular, it argues that the facts that settle conceptual-analysis questions are facts about the linguistic intentions of ordinary folk. The second thing this paper does is argue that if this metaphilosophical view is correct, then experimental philosophy is a legitimate methodology to use in trying to answer conceptual-analysis questions.

The purpose of this paper is to present and discuss a puzzle involving accommodation. The puzzle is based on three assumptions. The first assumption is that accommodation takes place after an utterance. The second assumption is that accommodation can make a difference to the truth-value of an utterance even if the utterance is not about the future. The third assumption is that something that takes place after an utterance cannot make a difference to the truth-value of the utterance unless the (...) utterance is about the future. Since these assumptions are jointly inconsistent, one of them must be false. The question is which one we ought to reject. The majority of the discussion is devoted to discussing each of the options, and the tentative conclusion is that the most plausible strategy is to reject the third thesis. That amounts to saying that something that takes place after an utterance can make a difference to the truth-value of the utterance even if the utterance is not about the future. (shrink)
