  1. Vagueness: A Conceptual Spaces Approach.Igor Douven, Lieven Decock, Richard Dietz & Paul Égré - 2013 - Journal of Philosophical Logic 42 (1):137-160.
    The conceptual spaces approach has recently emerged as a novel account of concepts. Its guiding idea is that concepts can be represented geometrically, by means of metrical spaces. While it is generally recognized that many of our concepts are vague, the question of how to model vagueness in the conceptual spaces approach has not been addressed so far, even though the answer is far from straightforward. The present paper aims to fill this lacuna.

    What Verities May Be.Igor Douven & Lieven Decock - 2017 - Mind 126 (502):386-428.
    Edgington has proposed a solution to the sorites paradox in terms of ‘verities’, which she defines as degrees of closeness to clear truth. Central to her solution is the assumption that verities are formally probabilities. She is silent on what verities might derive from and on why they should be probabilities. This paper places Edgington’s solution in the framework of a spatial approach to conceptualization, arguing that verities may be conceived of as deriving from how our concepts relate to each (...)

    Measuring Graded Membership: The Case of Color.Igor Douven, Sylvia9 Wenmackers, Yasmina Jraissati & Lieven Decock - 2017 - Cognitive Science 41 (3):686-722.
    This paper considers Kamp and Partee's account of graded membership within a conceptual spaces framework and puts the account to the test in the domain of colors. Three experiments are reported that are meant to determine, on the one hand, the regions in color space where the typical instances of blue and green are located and, on the other hand, the degrees of blueness/greenness of various shades in the blue–green region as judged by human observers. From the locations of the (...)

    What Is Graded Membership?Lieven Decock & Igor Douven - 2014 - Noûs 48 (4):653-682.
    It has seemed natural to model phenomena related to vagueness in terms of graded membership. However, so far no satisfactory answer has been given to the question of what graded membership is nor has any attempt been made to describe in detail a procedure for determining degrees of membership. We seek to remedy these lacunae by building on recent work on typicality and graded membership in cognitive science and combining some of the results obtained there with a version of the (...)

  5. Similarity After Goodman.Lieven Decock & Igor Douven - 2011 - Review of Philosophy and Psychology 2 (1):61-75.
    In a famous critique, Goodman dismissed similarity as a slippery and both philosophically and scientifically useless notion. We revisit his critique in the light of important recent work on similarity in psychology and cognitive science. Specifically, we use Tversky’s influential set-theoretic account of similarity as well as Gärdenfors’s more recent resuscitation of the geometrical account to show that, while Goodman’s critique contained valuable insights, it does not warrant a dismissal of similarity.

  7. Identity and Similarity.Igor Douven & Lieven Decock - 2010 - Philosophical Studies 151 (1):59-78.
    The standard approach to the so-called paradoxes of identity has been to argue that these paradoxes do not essentially concern the notion of identity but rather betray misconceptions on our part regarding other metaphysical notions, like that of an object or a property. This paper proposes a different approach by pointing to an ambiguity in the identity predicate and arguing that the concept of identity that figures in many ordinary identity claims, including those that appear in the paradoxes, is not (...)

    Quine's Weak and Strong Indispensability Argument.Lieven Decock - 2002 - Journal for General Philosophy of Science / Zeitschrift für Allgemeine Wissenschaftstheorie 33 (2):231-250.
    Quine's views on indispensability arguments in mathematics are scrutinised. A weak indispensability argument is distinguished from a strong indispensability thesis. The weak argument is the combination of the criterion of ontological commitment, holism and a mild naturalism. It is used to refute nominalism. Quine's strong indispensability thesis claims that one should consider all and only the mathematical entities that are really indispensable. Quine has little support for this thesis. This is even clearer if one takes into account Maddy's critique of (...)

    Cognitive Metaphysics.Lieven Decock - 2018 - Frontiers in Psychology 11:1700.
    In recent years philosophers have been interested in the methodology of metaphysics. Most of these developments are related to formal work in logic or physics, often against the backdrop of the Carnap-Quine debate on ontology. Drawing on Quine’s later work, I argue that a psychological or cognitive perspective on metaphysical topics may be a valuable addition to contemporary metametaphysics. The method is illustrated by means of cognitive studies of the notions “identity,” “vagueness,” and “object” and is compared to other extant (...)

  11. Putnam’s Internal Realism: A Radical Restatement.Lieven Decock & Igor Douven - 2012 - Topoi 31 (1):111-120.
    Putnam’s internal realism is aimed at reconciling realist and antirealist intuitions about truth and the nature of reality. A common complaint about internal realism is that it has never been stated with due precision. This paper attempts to render the position precise by drawing on the literature on conceptual spaces as well as on earlier work of the authors on the notion of identity.

    A Physicalist Reinterpretion of 'Phenomenal' Spaces.Lieven Decock - 2006 - Phenomenology and the Cognitive Sciences 5 (2):197-225.
    This paper argues that phenomenal or internal metrical spaces are redundant posits. It is shown that we need not posit an internal space-time frame, as the physical space-time suffices to explain geometrical perception, memory and planning. More than the internal space-time frame, the idea of a phenomenal colour space has lent credibility to the idea of internal spaces. It is argued that there is no phenomenal colour space that underlies the various psychophysical colour spaces; it is parasitic upon physical and (...)

    The Conceptual Basis of Numerical Abilities: One-to-One Correspondence Versus the Successor Relation.Lieven Decock - 2008 - Philosophical Psychology 21 (4):459 – 473.
    In recent years, neologicists have demonstrated that Hume's principle, based on the one-to-one correspondence relation, suffices to construct the natural numbers. This formal work is shown to be relevant for empirical research on mathematical cognition. I give a hypothetical account of how nonnumerate societies may acquire arithmetical knowledge on the basis of the one-to-one correspondence relation only, whereby the acquisition of number concepts need not rely on enumeration (the stable-order principle). The existing empirical data on the role of the one-to-one (...)

    Constraints on Colour Category Formation.Yasmina Jraissati, Elley Wakui, Lieven Decock & Igor Douven - 2012 - International Studies in the Philosophy of Science 26 (2):171-196.
    This article addresses two questions related to colour categorization, to wit, the question what a colour category is, and the question how we identify colour categories. We reject both the relativist and universalist answers to these questions. Instead, we suggest that colour categories can be identified with the help of the criterion of psychological saliency, which can be operationalized by means of consistency and consensus measures. We further argue that colour categories can be defined as well-structured entities that optimally partition (...)

  19. Quine's "Strictly Vegetarian" Analyticity.Lieven Decock - 2017 - The Monist 100 (2):288-310.
    I analyze Quine’s later writings on analyticity from a linguistic point of view. In Word and Object Quine made room for a “strictly vegetarian” notion of analyticity. In later years, he developed this notion into two more precise notions, which I have coined “stimulus analyticity” and “behaviorist analyticity.” The latter characterization is in many respects similar to Carnap’s characterization of analyticity based on semantic rules and can be seamlessly incorporated in a Carnapian project of explication. I explain why Quine failed (...)

    Qualia Compression.Lieven Decock & Igor Douven - 2013 - Philosophy and Phenomenological Research 87 (1):129-150.
    Color qualia inversion scenarios have played a key role in various philosophical debates. Most notably perhaps, they have figured in skeptical arguments for the fundamental unknowability of other persons’ color experiences. For these arguments to succeed, it must be assumed that a person's having inverted color qualia may go forever unnoticed. This assumption is now generally deemed to be implausible. The present paper defines a variant of color qualia inversion—termed ‘‘color qualia compression’’—and argues that the possibility of undetectable color qualia (...)

    Knowledge and Approximate Knowledge.Lieven Decock, Igor Douven, Christoph9 Kelp & Sylvia9 Wenmackers - 2014 - Erkenntnis 79 (S6):1129-1150.
    Traditionally, epistemologists have held that only truth-related factors matter in the question of whether a subject can be said to know a proposition. Various philosophers have recently departed from this doctrine by claiming that the answer to this question also depends on practical concerns. They take this move to be warranted by the fact that people’s knowledge attributions appear sensitive to contextual variation, in particular variation due to differing stakes. This paper proposes an alternative explanation of the aforementioned fact, one (...)

    Neo-Fregeanism Naturalized: The Role of One-to-One Correspondence in Numerical Cognition.Lieven Decock - 2008 - Behavioral and Brain Sciences 31 (6):648-649.
    Rips et al. argue that the construction of math schemas roughly similar to the Dedekind/Peano axioms may be necessary for arriving at arithmetical skills. However, they neglect the neo-Fregean alternative axiomatization of arithmetic, based on Hume's principle. Frege arithmetic is arguably a more plausible start for a top-down approach in the psychological study of mathematical cognition than Peano arithmetic.

    The volume assembles thirteen essays on logic, language and meaning, and is preceded by an introduction by Paul Gochet. Most of the papers were published between 1981 and 2000 in European journals such as Dialectica, Logique et Analyse, and Erkenntnis. The papers stand alone, yet throughout the book an overarching view of the relationship between pragmatics and semantics transpires clearly. Callaway defends a midway position between American analytic philosophy and American pragmatism. The result is a blend of Quine's scientific philosophy (...)

  24. Carnap and Quine on Some Analytic-Synthetic Distinctions.Lieven Decock - unknown
    I want to analyse the Quine-Carnap discussion on analyticity with regard to logical, mathematical and set-theoretical statements. In recent years, the renewed interest in Carnap’s work has shed a new light on the analytic-synthetic debate. If one fully appreciates Carnap’s conventionalism, one sees that there was not a metaphysical debate on whether there is an analytic-synthetic distinction, but rather a controversy on the expedience of drawing such a distinction. However, on this view, there can be no longer a single analytic-synthetic (...)

    Inception of Quine's Ontology.Lieven Decock - 2004 - History and Philosophy of Logic 25 (2):111-129.
    This paper traces the development of Quine's ontological ideas throughout his early logical work in the period before 1948. It shows that his ontological criterion critically depends on this work in logic. The use of quantifiers as logical primitives and the introduction of general variables in 1936, the search for adequate comprehension axioms, and problems with proper classes, all forced Quine to consider ontological questions. I also show that Quine's rejection of intensional entities goes back to his generalisation of Principia (...)

    In two papers in the mid-seventies, Quine has discussed an ontological deba-cle, the reduction of ontology to an ontology of pure sets only. This debacle, which weakened Quine’s interest in ontology, is the natural outcome of on-tological relativity, or, more precisely, the proxy-function argument. It is ex-plained how Quine unavoidably came to this conclusion. Moreover, it is ar-gued that the result is even more damaging for Quine’s philosophy than has hitherto been assumed. It is shown that in addition to an (...)

    Reflectance physicalism only provides a partial picture of the ontology of color. Byrne & Hilbert’ account is unsatisfactory because the replacement of reflectance functions by productance functions is ad hoc, unclear, and only leads to new problems. Furthermore, the effects of color contrast and differences in illumination are not really taken seriously: Too many “real” colors are tacitly dismissed as illusory, and this for arbitrary reasons. We claim that there cannot be an all-embracing ontology for color.

    The development and changes in Quine's ideas on universais are analysed, and especially the interplay of the notions of attribute, set and predicate is highlighted. In a first logico-mathematical part it is shown how Quine banned attributes as a result of extensionalism, and how set-theoretic solutions for Russell's paradox disturbed the easy view of each predicate determining a class. Quine even tried to formulate nominalistic theories without universais (sets). It is further shown how linguistic considerations played a role in Quine's (...)
