    A relational account of objects

    Full text link
    A relational account of objects provides a single unifying data model for both object-oriented programming languages and relational databases. Type variables used to represent unknown fields in the programming language correspond to discriminators in relations. Copyright © 2006, Australian Computer Society, Inc

    A Trope Theoretical Analysis of Relational Inherence

    Get PDF
    The trope bundle theories of objects are capable of analyzing monadic inherence (objects having tropes), which is one of their main advantage. However, the best current trope theoretical account of relational tropes, namely, the relata specific view leaves relational inherence (a relational trope relating two or more entities) primitive. This article presents the first trope theoretical analysis of relational inherence by generalizing the trope theoretical analysis of inherence to relational tropes. The analysis reduces the holding of relational inherence to the obtaining of certain other facts about entities of the trope theoretical category system. Moreover, I show that the analysis can deal with asymmetric and non-symmetric relations by assuming that all relation-like tropes are quantities. Finally, I provide an account of the spatial location of tropes in the difficult case in which tropes contribute to determining of the location of other entities

    Leibniz, the Young Kant, and Boscovich on the Relationality of Space

    Leibniz’s main thesis regarding the nature of space is that space is relational. This means that space is not an independent object or existent in itself, but rather a set of relations between objects existing at the same time. The reality of space, therefore, is derived from objects and their relations. For Leibniz and his successors, this view of space was intimately connected with the understanding of the composite nature of material objects. The nature of the relation between space and matter was crucial to the conceptualization of both space and matter. In this paper, I discuss Leibniz’s account of relational space and examine its novel elaborations by two of his successors, namely, the young Immanuel Kant and the Croat natural philosopher Roger Boscovich. Kant’s and Boscovich’s studies of Leibniz’s account lead them to original versions of the relational view of space. Thus, Leibniz’s relational space proved to be a philosophically fruitful notion, as it yielded bold and intriguing attempts to decipher the nature of space and was a key part in innovative scientific ideas

    Naturalizing Qualia

    Hill (2014) argues that perceptual qualia, i.e. the ways in which things look from a viewpoint, are physical properties of objects. They are relational in nature, that is, they are functions of objects’ intrinsic properties, viewpoints, and observers. Hill also claims that his kind of representationalism is the only view capable of “naturalizing qualia”. After discussing a worry with Hill’s account, I put forward an alternative, which is just as “naturalization-friendly”. I build upon Chirimuuta’s color adverbialism (2015), and I argue that we would better serve the “naturalizing project” if we abandoned representationalism and preferred a broadly adverbialist view of perceptual qualia

    On Crane’s Psychologistic Account of Intentionality

    Get PDF
    The intuition that we can think about non-existent objects seems to be in tension with philosophical concerns about the relationality of intentionality. Tim Crane’s psychologism removes this tension by proposing a psychologistic account of intentionality according to which intentionality is a purely non-relational notion. I argue that his account has counterintuitive consequences regarding our thoughts about existing objects, and as such is insufficiently plausible to convince us to reject the relationality of intentionality

    Relational Spacetime Ontology

    In the aftermath of the rediscovery of Einstein’s hole argument by Earman and Norton (1987), we hear that the ontological relational/substantival debate over the status of spacetime seems to have reached stable grounds. Despite Einstein’s early intention to cast GR’s spacetime as a relational entity à la Leibniz-Mach, most philosophers of science feel comfortable with the now standard sophisticated substantivalist (SS) account of spacetime. Furthermore, most philosophers share the impression that although relational accounts of certain highly restricted models of GR are viable, at a deep down level, they require substantival spacetime structures. SS claims that although manifold spacetime points do not enjoy the sort of robust existence provided by primitive identity, it is still natural to be realistic about the existence of spacetime as an independent entity in its own right. It is argued that since the bare manifold lacks the basic spacetime structures –such as geometry and inertia- one should count as an independent spacetime the couple manifold +metric (M, g). The metric tensor field of GR encodes inertial and metrical structure so, in a way, it plays the explanatory role that Newtonian absolute space played in classical dynamics. In a nutshell, according to the SS account of spacetime, one should view the metric field of GR as the modern version of a realistically constructed spacetime since it has the properties –or contains the structures- that Newtonian space had. I will try to dismantle the widespread impression that a relational account of full GR is implausible. To do so, I will start by highlighting that when turning back to the original Leibniz-Newton dispute one sees that substantivalism turns out prima facie triumphant since Newton was able to successfully formulate dynamics. However, to give relationalism a fair chance, one can also put forward the following hypothetical questions: What if Leibniz –or some leibnizian- had had a good relational theory? What role would geometry play in this type of theory? Would it be natural to view geometry and inertia as intrinsic properties of substantival space –if not spacetime? Would it still seem natural to interpret the metric field of GR along substantival lines regardless of the fact that it also encodes important material properties such as energy-momentum? After bringing these questions out into the light I will cast some important doubts on the substantival (SS) interpretation of the metric field. Perhaps the metric turns out to be viewed as a relational matter field. Finally, to strengthen the relational account of spacetime I expect to remove the possible remaining interpretative tension by briefly discussing the relevance of two important facts: i) Dynamical variables are usually linked to material objects in physical theories. The metric field of GR is a dynamical object so, I claim, it should be viewed as a matter field. ii) Barbour and Bertotti (BB2, 1982) have provided and alternative formulation of classical dynamics. They provide a “genuinely relational interpretation of dynamics” (Pooley & Brown 2001). Geometry and inertia become –contra SS- relational structures in BB2

    C. S. Peirce on the dynamic object of a sign: From ontology to semiotics and back

    Get PDF
    That reality, and in particular the (dynamic) objects of signs, are independent of our thoughts or other representations is a crucial thesis of Peirce’s realism. On the other hand, his semiotics implies the claim that all reality and all real objects are real for us only because of the signs we use. Do these two claims contradict, even exclude, each other? I will argue that both Peirce’s metaphysics and his semiotics provide a natural via media: a structural account of the openness of processes, featuring transitive relations, connects process ontology implicit in his evolutionary metaphysics and the relational, quasi-inferential features embodied in interpretational sequences of signs. It is shown that Peirce’s notion of a sign, its normative role and his account of the directional force of objects implies a sort of logical causality that supports the unity of objects. In this way sign sequences are able to relate flexibly sign use with contextually specified independent objects. That is to say, relational properties of object-oriented chains of interpretations provide sign users with a flexible, fallibilistic instrument able to capture by contingent identity relations (teridentity) of the identity of objects in changing situations.Includes: Comment by Francesco Bellucci (pp. 433–437)

    Imagination and Inner Intuition

    Get PDF
    In this paper I return to the question of whether intuition is object-dependent. Kant’s account of the imagination appears to suggest that intuition is not object-dependent. On a recent proposal, however, the imagination is a faculty of merely inner intuition, the inner objects of which exist and are present in the way demanded by object-dependence views, such as Lucy Allais’s relational account. I argue against this proposal on both textual and philosophical grounds. It is inconsistent with what Kant says about how the imagination functions and is ultimately incompatible with the relational account it is supposed to support. Kant’s account of the imagination remains a serious obstacle for the view that intuition is object-dependent
